The research team, comprised of knowledgeable scientists and educators, including doctoral student Hokuto Nagatakiya, Assistant Professor Shunsuke Kobayashi, Professor Ryuichi Tarumi, and Associate Professor Naoyuki Sakumichi, has turned that mystery into clarity. The team has successfully derived mathematical equations that provide a rigorous description of both the shape of the crack and the material’s deformation during this instigative process. This mathematical advancement advances our understanding of how viscoelastic properties influence crack dynamics significantly.

At the heart of their research lies the recognition that the sharpening of crack tips in polymer materials, like rubber, is not just a byproduct of external forces, but a fundamental characteristic directly tied to the material’s viscoelastic nature. This profound assertion challenges long-standing beliefs and opens new avenues for material design and failure prevention. The team confirmed the “viscoelastic trumpet theory,” proposed nearly three decades ago by Nobel Laureate Pierre-Gilles de Gennes, which states that crack propagation is a dynamic process characterized by distinct regions of deformation.

Viscoelasticity is a material property that elegantly combines elements of both elasticity and viscosity, allowing materials to behave differently under varying rates of deformation. Depending on how quickly a material is stretched or compressed, viscoelastic materials can exhibit rubber-like softness or glass-like rigidity. This adaptability is particularly crucial in applications where material performance can dictate safety and longevity, such as in the automotive and medical industries.

The implications of this finding extend far beyond academic interest; they set the groundwork for enhancing the durability of many viscoelastic materials. By controlling crack propagation and sharpening behavior, researchers may be able to innovate new products that are not only safer but also more environmentally sustainable by extending their useful life. Efforts aimed at improving the integrity of tires or other rubber products may lead to fewer accidents and reduced waste through more robust manufacturing processes.

This research was made possible through funding from Japan’s Science and Technology Agency (JST), highlighting a commitment to addressing urgent challenges through scientific inquiry. With support from initiatives like the Strategic Basic Research Programs, including ERATO, PRESTO, and the FOREST Program, the scientists have been able to push the boundaries of what we know about material science while innovating toward more effective solutions in the field.

Moreover, the study emphasizes the necessity of tackling complex phenomena in soft materials through a combination of computational simulations and mathematical modeling. Such interdisciplinary work signifies a methodological shift in how scientists understand and manipulate material behavior.

As the field of material science continues to evolve, understanding the nuanced interplay of properties within polymers remains critical. This study’s exploration of viscoelasticity and its connection to crack propagation not only illuminates fundamental physical principles but also paves the way for practical applications. Through ongoing research and innovation, we can anticipate developments that will greatly enhance our material culture and technological capabilities.

The collective efforts of the research team push the boundaries of what is known, providing a comprehensive framework for understanding dynamic crack behavior in viscoelastic materials. Future endeavors could very well tip the balance away from traditional materials toward new compounds that exhibit superior characteristics based on this newfound understanding. The quest for tougher polymers might soon yield exciting new possibilities that further influence sectors ranging from consumer goods to high-stakes industrial applications.

Overall, the exploration of crack dynamics in viscoelastic materials symbolizes a crucial chapter in material science, demonstrating how focused research efforts can result in significant advancements. The meticulous approach taken by these researchers contributes valuable insights that can lead to enduring improvements in various industries while enhancing safety and sustainability.

In conclusion, the synergy of rigorous mathematical modeling and practical insights garnered from this comprehensive study stands poised to influence the future of material development profoundly. As we move towards a more complex and interconnected world, the necessity for resilient materials becomes increasingly pertinent, and this pioneering work lays a solid foundation for addressing that challenge head-on.

Kim’s pottery experience provided her with an unexpected perspective on her scientific work. She noted the value of stepping outside of traditional scientific frameworks, allowing her to perceive her research through a different lens. “When you are immersed in the science, there are parts of your projects that you cannot see,” Kim reflected, emphasizing how engaging in creative activities can catalyze new ideas and solutions. This profound insight stems from her experience with pottery, where she meticulously applies wax to create intricate designs before layering them with paint. This technique of using wax as a stencil parallels the innovative methods she later adapted to manipulate nanoparticles in her research.

At the heart of Kim’s study lies the challenge of guiding nanoparticles to form desired structures. Her laboratory, led by Qian Chen, a professor and expert in nanomaterial engineering, focused on developing techniques that control the arrangement of these particles. The ultimate goal is to manipulate the fundamental properties of materials from the very start, eliminating previous limitations in nanoparticle assembly. This ambitious undertaking reflects a significant advancement in materials science, transcending beyond existing methodologies.

Kim’s artistic inspiration directly influenced her approach to nanoparticle synthesis. Partnering with her labmate, Chansong Kim, they devised a method to selectively coat specific regions of nanoparticles with molecular patches that project outward like microscopic hairs. This modification allows the particles to interact in predetermined ways, enhancing their assembly into larger, more complex structures. Achieving this precision was made possible through the use of iodide, which functions similarly to the wax stencils she employed in her pottery technique. The chemical’s selective binding capability prevents the hairs from attaching to designated spots, offering a newfound control over particle design.

This breakthrough opens doors to creating open-structured crystals that facilitate more complex material properties. Scientific experts, such as Sharon Glotzer from the University of Michigan, highlight the significance of this study as a substantial leap in the control of nanoparticle design. Glotzer articulated the transformative implications of this stenciling methodology, noting its potential to revolutionize the development of sophisticated materials that were previously unattainable. With such control over how nanoparticles adhere to each other, the boundaries of materials science are constantly being expanded.

The arrangements of these nanoparticles predominantly dictate their properties, especially in their interactions with light. Future applications could see nanomaterials adept at changing colors with structural modifications or empowering advanced imaging techniques that visualize entities smaller than the visible spectrum. These advancements could even pave the way for cutting-edge technologies, such as cloaking devices, fundamentally altering our interaction with the physical world.

To synthesize materials with these engineered nanoparticles, scientists suspend them in liquid environments where they self-assemble into crystal lattices driven by chemical and physical principles. By manipulating the characteristics of the surrounding liquid or altering the shapes of the particles themselves, researchers can influence their organization. However, the approach of modifying the surfaces of nanoparticles has proven to be a more effective strategy for yielding complex structures, as demonstrated in previous research highlighting the use of molecular patches to facilitate unique arrangements that were not achievable through conventional methods.

Despite previous efforts, controlling the exact placement of such surface modifications posed a significant hurdle for researchers. Kim’s earlier work successful in achieving hair-like molecular placement on the corners of triangular gold nanoparticles, yet the challenge persisted with diversifying nanoparticle shapes. Through meticulous review of prior studies, she identified the chemical iodide as a promising stencil material, traditionally used in the shaping of gold nanoparticles. The breakthrough moment arrived when Kim realized the potential of applying iodide in a strategic manner to achieve the precision required for her nanoparticle designs.

To further this endeavor, Kim collaborated with Kristen Fichthorn, a chemical engineer at Penn State University, renowned for her expertise in quantum-mechanical modeling. Fichthorn’s simulations provided valuable insights into how the surface atoms of Kim’s nanomaterials interact with various chemicals. These theoretical frameworks suggested that rigorous control of iodide and its relationship with linking molecules was essential to establish consistent stenciling patterns, setting the stage for more reliable fabrication techniques.

In tandem, simulations conducted by Tommy Waltmann, a physicist specializing in computational science, added another layer of validation to Kim’s experimental approach. Waltmann’s computer models elucidated the attachment of hair-like molecules to the linkers on nanoparticles and elucidated how these patchy structures assemble into crystal lattices. The synergy between the theoretical predictions and experimental observations marked a significant milestone in the study, offering researchers tangible pathways to manipulate nanoparticles for future applications.

The collaborative effort presented in this study could signify a transformative juncture in the field of materials science, where artistic innovation meets scientific inquiry to produce breakthrough technology. The implications of this research extend well beyond the confines of the laboratory, hinting at a future rich in advanced nanomaterials that could redefine industries ranging from electronics to biotechnology. As funding from esteemed organizations such as the U.S. Department of Energy and the National Science Foundation supports this groundbreaking work, the horizon of possibilities continues to expand, promising a new era of designer materials engineered from the nanoscale up.

In reflecting on her journey—from pottery artist to pioneering materials scientist—Kim encapsulates the heart of innovation. Her story serves as a beacon, revealing how seemingly unrelated fields can foster rich collaboration and spur advances in technology, ultimately leading to solutions that could reshape our understanding of materials and their potential.

In conclusion, this study not only showcases the innovative capabilities inherent in emerging nanotechnology but also emphasizes the significance of interdisciplinary approaches in scientific research.

The newly developed carbon membrane, named ultra-clean monolayer amorphous carbon (UC-MAC), is exceptional not only for its atomic thinness—just a single atom thick—but also for its unique amorphous structure. Unlike graphene, which is renowned for its perfectly ordered hexagonal carbon rings, UC-MAC is composed of a disordered network of five-, six-, and seven-membered carbon rings. This intrinsic atomic disorder is not a flaw; rather, it is a feature that imparts the membrane with angstrom-scale pores, with dimensions on the order of one ten-billionth of a meter. These pores can be precisely tuned to manipulate subatomic particles such as protons and molecular hydrogen ions (H₂⁺), enabling unprecedented control over particle behavior during filtration and splitting.

This novel pore structure fundamentally transforms how protons interact with the membrane, reducing scattering events that have long plagued proton therapy’s efficacy and safety. Proton therapy depends on the ability to deliver concentrated beams of protons to destroy cancerous tissues precisely while sparing surrounding healthy cells. However, current materials used in the ion source membranes cause considerable proton scattering, diminishing beam sharpness and control. UC-MAC addresses this issue by producing proton beams with twice the sharpness observed with graphene membranes and an astonishing 40-fold reduction in unwanted scattering compared to commercial carbon films, promising far safer and more effective cancer treatments.

A critical challenge in harnessing such advanced materials for practical use lies in their manufacturing. Traditional methods for producing ultra-thin carbon membranes are often lengthy, expensive, and susceptible to contamination by metal impurities, which degrade performance. The NUS research team devised a groundbreaking “disorder-to-disorder” (DTD) synthesis method, which fundamentally shifts the production paradigm. Utilizing inductively coupled plasma chemical vapor deposition (ICP-CVD), they can now fabricate an eight-inch UC-MAC sheet within seconds, free from detectable metal contamination. This industrially compatible, rapid process stands as a milestone in scalable production, bringing this sophisticated material closer to real-world application.

The research effort is notable for its cross-disciplinary collaboration, integrating expertise from synthetic chemistry, materials science, and theoretical physics. Key contributors include Professor Zeng Xiao Cheng from City University of Hong Kong, Assistant Professor Zhao Xiaoxu from Peking University, and Associate Professor Thomas Osipowicz from NUS’s Department of Physics. This diverse expertise was essential for addressing both the complex synthesis challenges and the fundamental understanding of the membrane’s atomic structure and particle filtration properties.

The scientific findings were detailed on July 28, 2025, in the peer-reviewed journal Nature Nanotechnology, cementing the research’s significance within the global scientific community. This high-impact publication signals not only academic recognition but also swells anticipation for practical breakthroughs enabled by UC-MAC.

Beyond the immediate promise in proton therapy, the researchers foresee UC-MAC’s porous, semiconducting structure as a versatile platform for future technologies. It offers compelling potential in energy solutions such as fuel cells and batteries where selective molecular separation and filtration are paramount. Catalysis processes, which depend heavily on precise molecular control, could also greatly benefit from the unique separation capabilities of the material’s angstrom-scale pores. Additionally, the semiconducting properties of UC-MAC might enable ultrathin electronic devices, potentially advancing the development of sub-2-nanometer integrated circuits — critical for sustaining the momentum of Moore’s Law in the coming decades.

This membrane’s extraordinary combination of thinness, cleanliness, and tunability is key to these applications. Its ultra-clean nature, achievable through the metal-free DTD synthesis route, ensures impurities do not interfere with functionality, improving reliability for sensitive uses in medicine and technology. Moreover, the ability to mass-produce large sheets rapidly paves the way for cost-effective fabrication of devices and components incorporating UC-MAC, contrary to the typical slow and costly lab-scale demonstrations of ultra-thin carbon films.

The improvement in proton beam quality demonstrated by UC-MAC is especially transformative for medical treatments. Proton therapy’s non-invasive nature makes it one of the most promising cancer treatment modalities, but its clinical effectiveness has been hampered by imprecise beam control, which can damage healthy tissue and limit radiation doses. The sharper proton beams enabled by UC-MAC membranes could allow clinicians unprecedented control over beam current and directionality, drastically mitigating side effects and enhancing treatment efficacy. This could translate into higher success rates, fewer complications, and better quality of life for cancer patients worldwide.

In conclusion, this innovative ultra-clean monolayer amorphous carbon membrane represents a landmark achievement in material engineering and medical technology. By combining atomic-level disorder with scalable clean manufacturing, the NUS-led team has created a material that not only surpasses graphene’s acclaimed properties but also opens new frontiers for quantum-scale particle manipulation. As subsequent studies and applications emerge, UC-MAC promises to be at the forefront of a new era in precision medicine, energy technology, and miniaturized electronics, embodying a rare fusion of fundamental science and practical impact.

At the core of this research is a novel approach to controlling the internal alignment of LCEs during the 3D printing process. Liquid crystal elastomers consist of molecular chains that include rigid building blocks known as mesogens. These mesogens can be aligned at the molecular scale, which significantly influences the macroscopic properties of the material. Achieving the right degree of alignment has historically involved a cumbersome process of trial and error, influencing the ability of researchers to manipulate material properties effectively and predictably.

The collaborative study led by researchers from prestigious institutions such as the Harvard John A. Paulson School of Engineering and Applied Sciences, Princeton University, and Lawrence Livermore National Laboratory, has laid down a comprehensive framework to produce liquid crystal elastomers with consistent and controllable alignment. This approach utilizes X-ray microbeam technology to allow for real-time measurement of mesogen alignment during the printing process, presenting a new paradigm in material science research.

The significance of this study cannot be overstated. By examining factors such as nozzle design and printing conditions, researchers were able to fine-tune parameters to achieve desired alignment in the material. The findings indicate that by adjusting parameters like nozzle shape, speed of ink extrusion, and temperature, teams could induce specific molecular-scale alignments that translate into desired behaviors at the macroscopic level, essentially producing tailored materials for specialized applications.

One of the transformative contributions of this work is the introduction of varying nozzle shapes to influence flow dynamics within the printing process. Tapered or hyperbolic nozzles, for instance, manipulate how the LCE ink exits the nozzle, directly affecting molecular orientation as the material is extruded. The researchers successfully demonstrated that altering the design not only improves the alignment of the mesogens but can also dramatically enhance the mechanical properties of the resulting printed structures.

The researchers employed wide-angle X-ray scattering measurements at specialized facilities to visualize the alignment of liquid crystal elastomers during the printing process. This in situ measurement capability provided unprecedented insights into how different fluid flow patterns and dye alignment interacted, allowing the team to refine their models of material behavior during the process of 3D printing. The ability to effectively see inside the printer itself offered critical data that can be crucial for future developments in both printing technology and material science.

Notably, the research revealed that the hyperbolic nozzle design produced a more uniform alignment of molecular chains compared to standard designs. This revelation has profound implications as it opens the door for creating LCE structures with optimized shape-morphing abilities, which could be harnessed for adaptive structures that can change shape and function according to varying environments or demands.

Moreover, the work conducted by the team signals a much-needed shift in the computational modeling of these complex materials. By integrating their empirical results into existing frameworks, the researchers proposed new methodologies for understanding flow-induced alignment in LCEs. Their findings provide invaluable data for the 3D printing community, which typically relies on a limited array of commercially available printheads and offers a clear call to action to explore the forgotten intricacies of nozzle geometry and flow to manipulate material responses innovatively.

The successful alignment of LCEs is crucial for their performance, as improved alignment correlates directly with the material’s actuation capabilities. The researchers found that when closely aligned, these liquid crystal chains exhibit significantly better responses to thermal stimuli, thus enhancing their applicability in soft robotics and adaptive systems. This work lays the groundwork not only for efficient material production but also for enhancing the intelligence and responsiveness of future soft actuators.

While soft robotics and responsive materials hold remarkable potential for various industries, the road to widespread adoption will necessitate continued refinement of printing techniques and materials development. This pioneering research underlines the importance of interdisciplinary collaboration between engineers, materials scientists, and physicists in endeavors aiming for the development of smart materials.

In conclusion, through their innovative research into the printing of liquid crystal elastomers, the team has not only advanced the field of 3D printing but has also set the stage for future explorations in responsive materials. Such initiatives promise to revolutionize not only the manufacturing sector but also significantly transform how adaptable technologies are conceived in medicine, robotics, and smart infrastructure. This research represents a significant leap toward harnessing the full potential of synthetic soft materials, bringing science fiction closer to reality.

Despite extensive research on a multitude of crystalline materials, most Weyl materials hitherto discovered have been overwhelmed by the influence of trivial electrons that obscure the presence of Weyl fermions. The successful synthesis of a material that supports a single pair of Weyl fermions without the interference of irrelevant electronic states represents not only a significant scientific breakthrough but also a culmination of years of theoretical predictions and experimental endeavors.

The research, published in the esteemed journal Nature, is the result of a four-year collaborative effort involving CEMS, the RIKEN Interdisciplinary Theoretical and Mathematical Sciences Program (iTHEMS), the Quantum-Phase Electronics Center (QPEC) at the University of Tokyo, the Institute for Materials Research at Tohoku University, and Nanyang Technological University in Singapore. The team ingeniously transformed a topological semiconductor into a Weyl semimetal, revisiting a strategy that had been theorized in 2011 but subsequently fell into relative obscurity within the scientific community.

Topological semiconductors, characterized by a small energy gap, can transition between insulating and conducting states. On the other hand, semimetals exist at the very brink of this transition, possessing a unique zero energy gap. This characteristic is exceedingly rare in natural materials, with graphene often cited as a prime example of a material featuring similar properties, particularly regarding its applications in flexible electronics and moiré physics.

The core material used in this groundbreaking study is bismuth telluride (Bi₂Te₃), a well-known topological semiconductor. Researchers carefully manipulated the chemical composition of the material by substituting chromium for bismuth, creating a compound denoted as (Cr,Bi)₂Te₃. This meticulous adjustment of the material’s properties allowed the team to unravel new physics beyond previously established topological semiconductor behavior, as evidenced by the observation of a large anomalous Hall effect (AHE).

The AHE observed in (Cr,Bi)₂Te₃ is particularly noteworthy, as it enables researchers to delve deeper into the material’s electronic structure. This uniquely simple electronic configuration has empowered the research team to quantitatively correlate their experimental results with theoretical predictions, thereby establishing a clear link between the large AHE and the emergent Weyl fermions. This connection signifies a pivotal moment in understanding quantum materials and their potential applications.

Leading author Ilya Belopolski expressed surprise at the discovery, noting that different research communities had already developed the necessary theoretical and experimental knowledge to synthesize this Weyl semimetal but had not effectively communicated. The success of this research illustrates the importance of collaboration across disciplines and highlights how missed opportunities can arise in the absence of dialogue between different scientific fields.

Belopolski attributed the emergence of this critical insight to the unique atmosphere fostered at RIKEN, where brilliant researchers come together in a creatively stimulating environment. The collaboration between talented research groups from various countries exemplifies the global pursuit of scientific knowledge and underlines how a collaborative approach can lead to significant breakthroughs that might otherwise remain unrealized.

One of the most exciting potential applications of this newly discovered Weyl semimetal lies in terahertz (THz) technology. Classical semiconductors are generally unable to absorb photons below certain energy thresholds dictated by their energy gaps. However, semimetals, with their zero energy gap, can effectively absorb light across the THz frequency range. This unique property positions Weyl semimetals as promising candidates for creating and detecting THz light, opening doors to potential advancements in communication technologies and sensor applications.

The implications of this discovery extend beyond just terahertz applications, as the research team anticipates exploration into high-performance sensors, low-power electronics, and innovative optoelectronic devices. The enthusiasm surrounding the prospects of this new quantum phase of matter embodies the dynamic research atmosphere at CEMS, where emerging technologies continuously push the boundaries of material science.

Lixuan Tai, a postdoctoral researcher who joined the Strong Correlation Quantum Transport Laboratory close to the publication of the findings, expressed exhilaration regarding the opportunities that this new Weyl semimetal presents for ongoing and future research. The team is poised to leverage the characteristics of this material to further explore its unique phases and properties, potentially sparking a wave of discoveries in quantum materials.

As researchers continue to delve into the properties of the ideal Weyl semimetal, they anticipate a rich landscape of inquiry that will lead to new methodologies and technological innovations. The intersection of theory and experimentation in this context illustrates the remarkable progress being made in the understanding of quantum materials, a field that will undoubtedly yield significant advancements in science and technology for years to come.

The synthesis of the ideal Weyl semimetal thus represents a transformative achievement in the realm of quantum transport and materials science. It paves the way for further exploration and understanding of Weyl fermions and their associated electromagnetic properties, signifying a potential turning point in how researchers approach the study of quantum materials and highlights the value of collaboration in unlocking the mysteries of the universe.

As the research community continues to build upon this foundation, the exciting prospects for the development of new devices, sensors, and methodologies driven by the unique properties of this Weyl semimetal will likely be a central theme in future scientific discourse. This breakthrough not only illustrates the potential of quantum materials but also serves as an exemplar of what can be achieved through sustained collaboration and innovative thinking in scientific research.
