MXenes, first discovered just over a decade ago in 2011, represent a versatile family of inorganic two-dimensional materials comprising layers of transition metals combined with carbon or nitrogen atoms. What sets MXenes apart are the atoms, known as surface terminations, that cap the outermost layers. These terminations critically influence the material’s behavior—controlling electron transport, stability, and interactions with light and heat. Until now, however, MXenes have been limited by the uncontrolled, heterogeneous distribution of these surface groups, discovered through conventional chemical etching techniques.

Traditional MXene synthesis leverages chemical etching methods involving harsh acids or reactive chemicals that produce a patchwork of oxygen, fluorine, chlorine, and sometimes other terminations scattered randomly on the surface. This disorder leads to electron scattering akin to potholes on a highway, severely impeding charge mobility and undermining the potential of MXene-based devices. Recognizing these bottlenecks, a collaborative research team led by scientists at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and TU Dresden pioneered an alternative strategy, deftly circumventing these constraints.

Their new method—termed the GLS synthesis route—eschews harmful chemicals altogether, instead deploying a triphasic system that involves solid MAX phases, molten salts, and iodine vapor in a carefully orchestrated reaction environment. This triphasic setup allows the researchers to dictate exactly which halogen atoms terminate the MXene surfaces, such as chlorine, bromine, or iodine, creating well-ordered, homogeneous surface configurations and dramatically lowering impurities. This level of control, unparalleled in the field, fundamentally alters MXene performance.

Demonstrating the robustness of this synthesis, the team synthesized MXenes from eight distinct MAX phases, underscoring the method’s versatility and broad applicability across the MXene family. To complement their experimental efforts, density functional theory (DFT) calculations provided deep theoretical insight into how these precisely engineered terminations stabilize the structure and govern electronic properties. The fusion of empirical and computational approaches guided the development of MXenes with tailored functional characteristics and enhanced stability.

One compelling example illustrating the leap in performance is the titanium carbide MXene Ti₃C₂. In conventional chemical etching, Ti₃C₂ terminates with a mixture of chlorine and oxygen—a combination that muddles its intrinsic electronic properties. However, when synthesized via the GLS method, Ti₃C₂Cl₂ exhibited a perfectly chlorine-terminated surface, meticulously ordered with no detectable contaminants. The performance improvements were staggering: macroscopic conductivity surged by a factor of 160, terahertz-frequency conductivity increased thirteenfold, and electron charge carrier mobility skyrocketed nearly four times higher.

These phenomena stem directly from the ordered surface halogens acting as a smooth highway for electron travel, free of the impediments that plagued previous MXenes. Quantum transport simulations reinforced these experimental outcomes, revealing that the uniform chlorine termination dramatically minimized electron trapping and scattering events at the atomic scale. This clear microscopic understanding validates the technique’s power to unlock the intrinsic potential of MXenes.

The implications extend far beyond electrical conductivity. By varying the halogen type, researchers observed altered absorption profiles of electromagnetic radiation across different frequency bands. Chlorine-terminated MXenes strongly absorb waves in the 14-18 GHz range, while bromine- and iodine-terminated variants interact uniquely with other regions of the electromagnetic spectrum. This tunable absorption makes MXenes viable candidates for tailor-made radar-absorbing coatings, electromagnetic interference shielding, and emerging high-frequency wireless communication components.

Even more striking is the ability to “dial in” mixed halogen terminations by blending halide salts, yielding dual or triple surface terminations with precise compositional control. This strategy unlocks an unprecedented material design space where electronic, catalytic, energy storage, and photonic properties can be finely tuned for specific target applications. The method transforms MXene surface chemistry from an uncontrolled inevitability into a deliberate design parameter, laying the groundwork for highly customized two-dimensional materials.

Crucially, the GLS synthesis method stands out for its gentleness and environmental friendliness compared to traditional aggressive chemical approaches. By eliminating toxic reagents and facilitating synthesis under moderate conditions, the process not only produces superior materials, but also aligns with sustainable manufacturing principles—a key consideration for future scalability in industrial settings.

This breakthrough heralds a new era for MXene chemistry and engineering. As the field transitions from MXene discovery to application, the ability to fabricate materials with atomically precise surface configurations empowers researchers to exploit their full range of electrical, optical, and chemical functionalities. The method promises to accelerate innovation in flexible electronics, rapid data transmission technologies, and next-generation optoelectronics.

Looking forward, the research community anticipates that the GLS synthesis approach will serve as a foundational platform upon which even more complex and multifunctional MXene architectures can be built. By marrying theoretical predictions with experimental precision, scientists are poised to explore the vast combinatorial landscape of MXene surface chemistries, optimizing materials for an array of cutting-edge technologies.

In sum, the triphasic GLS method represents a paradigm shift in MXene fabrication, yielding materials with highly ordered, impurity-free halogen terminations tailored to specific properties. The dramatic enhancement of electrical transport, along with the ability to customize electromagnetic response, promises to expand the applications of MXenes far beyond their current scope. As researchers continue to unlock the secrets of these surfaces, the stage is set for MXenes to become cornerstone materials of the next technological revolution.

The investigative team, spearheaded by Liao, Sha, O’Leary, and collaborators, has deployed Atomic Electron Tomography (AET)—a sophisticated imaging technique capable of mapping atomic positions in 3D—to tackle the intricacies inherent in non-crystalline structures. Their rigorous study, published in Nature in early 2026, details a robust, multi-step analytical framework that overcomes prior limitations by integrating advanced image preprocessing, denoising algorithms, and meticulous projection alignment and normalization. This comprehensive workflow ensures the extraction of accurate and reliable 3D atomic coordinates along with elemental identification, a crucial leap in characterizing amorphous solids beyond traditional means.

Central to their approach is the optimization of AET data handling. The researchers emphasize how pre-processing steps, including thorough noise reduction and normalization, significantly enhance the quality of the tomographic reconstructions. By employing advanced reconstruction algorithms tailored to mitigate artifacts typical in amorphous material imaging, the team achieves stringent positional precision, enabling visualization of atoms with sub-angstrom accuracy. This level of precision is pivotal in differentiating subtle atomic arrangements that define properties unique to amorphous phases.

The study makes a comparative evaluation against earlier methodologies, demonstrating superior performance across multiple parameters. Utilizing multislice simulations on amorphous nanoparticles composed of silicon, silicon-germanium-tin (SiGeSn), and cobalt-palladium-platinum (CoPdPt), their workflow exhibits enhanced positional precision and elemental classification accuracy at various noise thresholds. This comparative analysis not only validates the methodological rigor but also establishes quantitative benchmarks that future investigations can adopt to guarantee reliability in amorphous structure determination.

Intriguingly, for the ternary alloy CoPdPt, the method achieved remarkable elemental identification rates: detecting 95.1% of cobalt atoms, 99.0% of palladium, and a flawless 100% of platinum atoms. Even more impressive was the pinpoint positional accuracy, measured at 29 pm for cobalt, 12 pm for palladium, and an extraordinary 6 pm for platinum atoms. These values are unprecedented for amorphous materials, particularly given the realistic electron dose conditions under which the reconstructions were obtained. Such precision heralds new possibilities for linking atomic arrangement to macroscopic properties directly, providing insights that have eluded materials science for decades.

Beyond elemental mapping, the research highlights the broader implications of this breakthrough. The refined ability to resolve local atomic packing, short- to medium-range order, and heterogeneity in amorphous systems paves the way for optimizing material functionalities across several domains. This has immediate relevance for applications reliant on thin-film semiconductors, amorphous magnetic components, and emerging quantum devices, where atomic-level understanding could translate into enhanced performance, stability, and longevity.

The rigorous computational underpinning of the proposed framework merits attention. By combining physics-based simulation models with machine learning-driven classification techniques, the researchers circumvent common pitfalls such as atom misidentification or inaccurate position refinement. The use of multislice simulations to generate synthetic datasets ensures the method’s applicability across different compositions and experimental conditions, showcasing its versatility and robustness. Importantly, this hybrid approach harmonizes experimental data with theoretical constructs to push the boundaries of what is experimentally achievable.

Another remarkable aspect of the study is its holistic nature: it does not merely depend on single components of the imaging or processing pipeline but underscores the synergy among image denoising, alignment, tomographic reconstruction, atom tracing, elemental classification, and final atomic position refinement. Each step in the workflow incrementally enhances the fidelity of the final 3D atomic model, demonstrating that state-of-the-art results demand a comprehensive, well-integrated approach rather than piecemeal improvements.

The adoption of this refined AET methodology could revolutionize the way scientific communities approach the structural study of disordered systems. Historically, amorphous materials have often been characterized by indirect techniques such as X-ray diffraction pair distribution functions, neutron scattering, or reverse Monte Carlo simulations, which provide averaged or probabilistic atomic information. The ability to reconstruct individual atomic positions in three dimensions with elemental specificity constitutes a quantum leap from these averaged structural models.

Moreover, the implications extend beyond materials science. In biophysics, chemistry, and nanotechnology, where understanding non-periodic atomic structures is crucial, this imaging and analysis framework can inform the rational design of novel materials and molecular complexes. It has the potential to inspire advancements in phase-change memory devices, enhance the efficiency of photovoltaic materials, and contribute to the development of next-generation quantum sensors and detectors by delivering atomic-scale insights previously deemed unattainable.

While the presented advances are remarkable, the authors acknowledge ongoing challenges and future directions. Further refinement in dose efficiency, expansion to higher atomic number materials, and integration with in situ experimentation will be key to broadening the applicability of this technique. Nonetheless, the current findings lay a solid foundation, providing a meticulously validated protocol and performance metrics that can serve as a blueprint for subsequent studies aiming to elucidate the atomic landscape of amorphous solids.

In sum, this pioneering work establishes clear, practical guidelines to achieve accurate 3D atomic resolution in non-crystalline materials using Atomic Electron Tomography augmented by advanced computational processing. It convincingly demonstrates that the longstanding barriers to direct atomic mapping of amorphous materials can be overcome. This study is poised to influence material science profoundly, opening doors to innovations in material design, characterization, and application that hinge on detailed atomic-scale comprehension.

As the scientific community grapples with the complexity of amorphous matter’s structural mysteries, the integration of experimental prowess with computational ingenuity in this research provides a transformative toolkit. It challenges the notion that disorder equates to inscrutability at the atomic level and instead frames amorphous materials as accessible entities, whose secrets can be cracked with the right combination of technology and analytical sophistication.

Ultimately, this work not only illuminates the atomic structure of amorphous solids but also reshapes the methodological landscape of 3D structural analysis in materials science. It stands as a testament to the potential unlocked when experimental electron microscopy and computational modeling converge harmoniously, setting a new standard for atomic resolution imaging in the presence of disorder.

Triboluminescence, the emission of light resulting from the mechanical action of rubbing, striking, or fracturing materials, has traditionally been a niche area focused mostly on inorganic crystals and some organic compounds. This research thrusts metal halide perovskite films into the spotlight as promising candidates for this phenomenon, thereby expanding the understanding of their fundamental properties beyond photoluminescence and electroluminescence. The work bridges the gap between material science and optical physics by demonstrating that perovskite films can emit light when subjected to mechanical stimuli, illuminating new scientific possibilities.

Metal halide perovskites have been widely celebrated for their efficacy in solar cells, LEDs, and photodetectors due to their exceptional charge carrier mobility, tunable bandgap, and ease of fabrication. However, triboluminescence in these materials had not been adequately characterized prior to this study. The researchers utilized a meticulously designed experimental setup capable of applying controlled mechanical force to the perovskite films, capturing the resulting emission spectra with high temporal and spatial resolution. This rigorous methodology allowed them to observe and analyze subtle luminescent behaviors triggered by mechanical perturbations.

The triboluminescent light emission in metal halide perovskite films was found to be strongly dependent on the structural integrity and phase of the crystals. The material’s crystalline lattice and its defect states emerged as critical determinants for the intensity and wavelength distribution of the emitted light. Crucially, the team demonstrated that altering processing conditions to modulate the film’s morphology could fine-tune the triboluminescent properties. This insight has profound implications for designing mechanically responsive optoelectronic devices.

An intriguing finding reported by the authors is the role of lattice distortions induced by mechanical stress in activating specific electronic transitions that produce visible light. They provide theoretical and experimental evidence linking strain-induced changes in the perovskite crystal field with light emission. These observations suggest a new mechanism of mechanoluminescence distinct from conventional photophysical processes. The discovery opens avenues to engineer perovskite materials with tailored triboluminescent capabilities through strain engineering.

In addition to fundamental insights, the study explores potential applications of triboluminescent perovskite films. The ability to emit light under mechanical triggers could be exploited in stress sensors, mechanical damage detectors, and interactive optoelectronic devices that respond physically to external forces. For example, wearable technologies might integrate these films to provide real-time visual feedback on pressure or deformation, enabling new modes of human-machine interaction.

The research team also addresses key challenges related to the stability and longevity of triboluminescent perovskite films. Given that metal halide perovskites often suffer from environmental degradation and ion migration under operational stresses, the study investigates encapsulation strategies and compositional engineering that enhance material robustness without compromising triboluminescent performance. These findings emphasize the importance of developing durable triboluminescent materials for practical deployment.

Methodologically, the authors employed advanced microscopy techniques and spectroscopy coupled with mechanical testing to dissect the spatial distribution of luminescence within the films. This comprehensive approach revealed localized sites of intense emission correlating with microcracks and grain boundaries, implicating nanoscale heterogeneities as essential contributors to triboluminescence. The integration of imaging and mechanical characterization thus presents a powerful toolkit for future mechanoluminescence research.

Moreover, the theoretical framework underpinning the study incorporates quantum mechanical modeling combined with continuum mechanics to elucidate the coupling between mechanical deformation and electronic excitations in perovskites. This interdisciplinary modeling sheds light on the energy transfer pathways and provides predictive capability for optimizing triboluminescent responses through material design. The synergy of experiment and theory showcases the maturation of triboluminescence as a field.

The implications of this research transcend laboratory curiosities. As perovskite optoelectronics continue to advance, integrating triboluminescent properties promises multifunctional platforms that combine energy harvesting, sensing, and display capabilities. This multifaceted functionality aligns perfectly with the modern demand for smart, adaptive materials in consumer electronics, health monitoring, and structural health diagnostics. The work stands at the frontier of sustainable, responsive materials development.

Importantly, the authors highlight the environmental impact considerations of deploying perovskite films in triboluminescent devices. By linking material innovation with green chemistry principles, they advocate for lead-free or low-toxicity alternatives and scalable fabrication processes that minimize ecological footprint. This conscious approach situates triboluminescent perovskites within the broader context of responsible materials science and circular economy models.

Future research directions outlined include exploring triboluminescence under varying mechanical modes such as tension, bending, and shear, to fully map the emission profiles. Investigating temperature dependence and long-term cycling stability remains critical for practical application. Additionally, expanding material compositions to incorporate mixed halides and organic-inorganic frameworks may reveal novel triboluminescent behaviors and enhance tunability.

The study also points to interdisciplinary collaborations between physicists, chemists, and engineers as vital for translating triboluminescent metal halide perovskites from experimental novelties to commercial realities. Developing integrated devices that harness light emission under mechanical cues requires advances in circuitry design, flexible substrates, and system-level optimization. This holistic approach will likely catalyze a new era of smart, light-emitting sensors.

In sum, Tian and colleagues’ investigation into the triboluminescence of metal halide perovskite films represents a seminal contribution that expands the functional landscape of perovskite materials. Their findings not only deepen fundamental understanding but also chart a promising course for innovative optomechanical devices. As this dynamic field unfolds, the blend of mechanical action and photonic response embodied by these films is poised to inspire new scientific discovery and technological breakthroughs.

Light, a ubiquitous form of energy, has been shown to possess the capability to induce significant changes in the properties of materials, particularly magnetic metals. The research, led by Associate Professor Ryo Hanai and collaborators from various institutions, posits that by irradiating magnetic materials with light at specified frequencies, one can initiate a process that drives two magnetic layers into complex, synchronized motion, described as a “chase-and-run” dynamic. This revelation introduces a new paradigm in non-equilibrium materials science and opens avenues for innovative applications in areas such as spintronics and quantum computing.

In equilibrium, systems typically obey the laws of thermodynamics and mechanics, resulting in predictable interactions between components. Nevertheless, when we delve into non-equilibrium conditions—such as those encountered in biological systems or active matter—the interactions can display non-reciprocal characteristics. These interactions are evident in many natural occurrences, such as the behavior of neurons in the brain or interactions within ecosystems. The question arises: can we replicate these non-reciprocal characteristics within solid-state electronic systems, and the answer provided by this research is a resounding yes.

The researchers utilized a method, termed dissipation engineering, which involves manipulating how energy is dissipated within magnetic metals. By creating a scenario where certain spin states receive more energy than others, the researchers successfully initiated non-reciprocal interactions. The cornerstone of their findings is the Ruderman–Kittel–Kasuya–Yosida (RKKY) interaction, a well-known exchange interaction in magnetic systems. By targeting the interaction through light stimulation, they were able to introduce a non-reciprocal nature to a process traditionally governed by equilibrium and reciprocity.

As the team explored this idea further, they focused on bilayer ferromagnetic systems, which consist of two magnetic layers interacting with each other. When exposed to certain frequencies of light, these layers exhibited a non-reciprocal phase transition, an effect characterized by a dynamic where one layer tends to align while the other exhibits a tendency to anti-align. This creates a unique chiral phase, marked by continuous rotation of magnetization, defying the expected behavior according to Newton’s third law. The implications of such a finding are profound, hinting at the possibility of new materials and devices that leverage non-reciprocal interactions.

Furthermore, the research indicates that the light intensity required to induce these non-reciprocal phase transitions is not beyond current experimental capabilities. This aspect highlights an important transition from theoretical prediction to potential real-world application, as it opens the door for experimental validation and the discovery of new quantum materials that could enable advanced technologies.

The coupling between active matter phenomena and solid-state physics not only enriches the understanding of materials but may also contribute to the development of next-generation spintronic devices. These devices, leveraging the intrinsic spin of electrons, promise faster processing speeds and enhanced functionalities compared to their charge-based counterparts. As such, the pursuit of organized non-reciprocal dynamics could yield devices that are more efficient and represents a shift in how we manipulate information at the quantum level.

Moreover, the insights gained from these experiments could have beneficial impacts on various fields. For instance, exploring non-reciprocal interactions in Mott insulating phases of strongly correlated electrons could lead to the discovery of new superconducting mechanisms. Similarly, the interplay between light and magnetic states could facilitate the realization of frequency-tunable oscillators, thus enhancing communication technologies.

The quest to identify intrinsic topological superconductors has challenged physicists for decades. These unique materials exhibit exotic surface states that host Majorana fermions—quasi-particles theorized to encode quantum information in a manner inherently resistant to environmental disturbances. While many candidate materials have been proposed, none have conclusively satisfied all the strict criteria to be classified as intrinsic topological superconductors. Now, the team at UCC, leveraging an innovative experimental approach, has decisively evaluated one of the most promising candidates: Uranium ditelluride (UTe₂).

UTe₂, discovered in 2019, rapidly garnered scientific attention for its superconducting and possibly topological properties. Traditional experimental techniques were insufficient to unravel the complexities of this material’s electronic and quantum states. To address these limitations, Professor Séamus Davis of UCC, an expert in quantum physics, developed a novel “Andreev” scanning tunneling microscopy (STM) mode. This technology, available exclusively in three laboratories worldwide—including UCC, Oxford University, and Cornell University—enabled the team to peer beneath the electronic “noise” and directly observe the characteristics indicative of topological superconductivity.

Applying this espionage-like tool, PhD researcher Joe Carroll and Marie Curie postdoctoral fellow Kuanysh Zhussupbekov spearheaded the investigations into UTe₂’s surface states. Unlike conventional STM, which uses metallic probes that inevitably mix signals from trivial surface electrons, the Andreev STM employs a superconducting tip. This methodology filters out the normal electron contributions, isolating the signature of Majorana fermions. The precision of this technique permitted an unprecedented, unequivocal assessment of whether UTe₂ embodies intrinsic topological superconductivity.

The findings revealed that UTe₂ indeed operates as an intrinsic topological superconductor. Yet, intriguingly, it does not conform precisely to the archetype physicists had long sought. Instead, the material’s superconducting and topological wave functions exhibit a more nuanced symmetry and complexity, expanding the conceptual landscape of what qualifies as an intrinsic topological superconductor. These insights deepen the understanding of superconductivity’s quantum mechanical foundations and open new avenues for material synthesis aimed at optimizing quantum information applications.

Professor Davis emphasized the novelty of the approach by explaining that previous techniques relied heavily on metallic probes that contributed extraneous electron signatures, complicating data interpretation. By contrast, this superconductor-based STM eradicates the confounding background electrons, enabling a “pure” visualization of the zero-energy surface states where Majorana modes reside. This purity is critical because these Majorana fermions are theorized to enable quantum bits (qubits) to maintain coherence far longer than conventional systems, a holy grail for quantum computing.

The implications for the quantum computing industry are profound. As global efforts intensify to build scalable quantum processors, the challenges of qubit decoherence and error correction remain formidable obstacles. Synthetic topological superconductors, composed of engineered stacks of conventional materials, have shown promise but introduce complexity and scalability concerns. The UCC team’s demonstration that a single, intrinsic material like UTe₂ can host the requisite topological states hints at the potential to simplify quantum processor architectures significantly.

This breakthrough aligns with initiatives such as Microsoft’s Majorana 1 chip, the world’s first quantum processing unit driven by a topological core using synthetic superconductors. The Davis Group’s methodology offers an alternative strategy—one that could replace engineered heterostructures with straightforward single-crystal materials, reducing fabrication complexity and enhancing qubit density on chips. The ability to incorporate more qubits without proportionally increasing error rates is vital for the realization of practical quantum algorithms capable of tackling classically intractable problems.

Moreover, the use of Andreev STM as a diagnostic instrument transcends the immediate focus on UTe₂. It equips researchers with a universal probe capable of validating other candidate superconductors’ topological nature. This technological leap empowers the scientific community to systematically filter and identify materials with intrinsic topological superconductivity from a vast chemical universe, accelerating discovery cycles and guiding theoretical modeling.

In addition to its technical contributions, this research exemplifies international collaboration’s role in advancing quantum materials science. Input from distinguished theoretical physicist Prof. Dung-Hai Lee (UC Berkeley) and materials synthesis experts from Washington University and the University of Maryland enriched the study’s multidisciplinary depth, ensuring a comprehensive approach bridging theory and experiment.

While UTe₂’s exact topological superconductor class may differ from classic expectations, its confirmation as an intrinsic platform hosting Majorana modes represents an essential puzzle piece in the quantum computing saga. The work sets a new standard for experimental rigor and innovation, marking a hopeful trajectory toward building quantum processors that transcend today’s limitations on coherence time, qubit number, and error rates.

In sum, the Davis Group’s pioneering use of Andreev STM to visualize zero-energy surface states in UTe₂ is more than a scientific milestone—it heralds a new era in material exploration tailored for quantum technologies. Their findings cast light on the subtle symmetries governing superconductivity’s quantum phases and unlock practical pathways toward scalable, fault-tolerant quantum computing hardware. As the quantum race accelerates, such breakthroughs bridge the gaps between fundamental physics, material engineering, and the computational revolutions of tomorrow.
