For over 100 years, diamonds have been categorized as non-piezoelectric due to their symmetrical crystalline structure, which was assumed to lack the inherent ability to generate electric charge under mechanical stress. Despite diamond’s exceptional mechanical robustness, ultra-high thermal conductivity, and large electronic bandgap, its role has been relegated primarily to that of a passive substrate in MEMS devices, supporting layers of genuinely piezoelectric materials. The intrinsic piezoelectric activity, or the ability to convert mechanical strain into an electrical signal, was considered absent in diamond, thereby limiting its utility in electromechanical applications.

The research overcomes this limitation by exploiting an innovative edge-exfoliation technique to fabricate polycrystalline diamond membranes that are not only ultrathin but also remarkably flexible. This mechanical pliability enables the otherwise rigid and brittle diamond to experience significant bending and deformation without fracture. When these membranes undergo controlled flexural strain, the team detected stable and reproducible voltage signals, a clear indication of piezoelectric behavior. This finding is unprecedented and points to previously untapped functionalities in diamond structures.

To rigorously rule out artefacts from environmental noise and other electrostatic effects such as triboelectricity, the experimental procedures included systematic mechanical cycling tests within carefully controlled environments. The results were consistently repeatable, affirming that the voltage signals arose from an intrinsic response within the diamond membrane rather than external interference. This level of scientific rigor strengthens the credibility of their claims and paves the way for new theoretical and practical explorations of diamond’s electromechanical properties.

At the atomic scale, first-principle computational modeling reveals that the piezoelectricity primarily originates at grain boundaries within the polycrystalline diamond. Unlike monocrystalline diamond, polycrystalline forms harbor asymmetries and defects at grain boundaries, which appear to accumulate charge polarization when mechanical stresses are applied. This localized charge imbalance generates an electric potential difference across the upper and lower surfaces of the membrane, effectively realizing a piezoelectric effect. It’s a profound insight that grain boundary engineering can unlock functionalities forbidden in perfect diamond lattices.

The implications of this discovery transcend fundamental materials science. Diamonds’ exceptional biocompatibility, chemical inertness, and mechanical durability make them ideal for medical and energy technologies. Piezoelectric diamond membranes could revolutionize implantable medical devices by providing self-sustaining power sources or highly sensitive deformation sensors capable of monitoring physiological signals in real-time without the need for external batteries. This represents a paradigm shift towards autonomous biomedical devices that harness body movement or biological forces for power generation.

Moreover, the exceptional thermal and mechanical properties of diamond membranes mean they could power next-generation energy harvesting systems with unprecedented stability and longevity. Devices built from piezoelectric diamond could operate reliably under harsh environmental conditions, opening applications in aerospace, industrial sensing, and remote infrastructure monitoring where durability and performance are paramount. This discovery heralds a new era of ultra-reliable micro-energy systems that utilize diamond’s robust nature alongside its newfound piezoelectric capabilities.

The research also introduces a compelling new avenue for material functionalization by manipulating microstructural features such as grain boundaries. This strategic structural engineering could be extended to other materials traditionally considered non-piezoelectric, potentially expanding the library of piezoelectric materials by harnessing microstructural asymmetries rather than relying solely on bulk crystal symmetry. It challenges conventional wisdom and may inspire a re-examination of other hard, inert materials that were previously overlooked for electromechanical applications.

Diamond’s integration into MEMS has typically focused on leveraging its mechanical and thermal attributes, but this discovery significantly broadens its application scope. The ability to generate electrical signals directly from a pure diamond membrane without additional piezoelectric layers simplifies device architecture, reduces fabrication complexity, and enhances device longevity. Future MEMS devices could be more compact, efficient, and resilient, with diamond serving as both substrate and active piezoelectric element.

Professor Zhiqin Chu’s team demonstrated a methodical blend of experimental precision and theoretical insight to validate this phenomenon. Their multidisciplinary approach combined advanced fabrication techniques with rigorous electrical characterization and comprehensive quantum mechanical modeling. Such integrative research exemplifies cutting-edge innovation at the intersection of physics, materials science, and engineering, setting a new benchmark for what is possible with carbon-based materials.

Looking ahead, this discovery invites intensified research into optimizing diamond membrane fabrication, tuning grain boundary characteristics, and tailoring their piezoelectric response. Scaling up production while maintaining membrane flexibility and piezoelectric efficiency will be key to commercial applications. The research community will also explore the integration of piezoelectric diamond membranes into complex device architectures, aiming to realize fully autonomous sensors, actuators, and energy harvesters with superior performance and durability.

The University of Hong Kong’s pioneering work fundamentally transforms our understanding of diamond’s properties and broadens the horizon for its practical applications. By uncovering an unexpected piezoelectric effect in a traditionally non-piezoelectric material, this research disrupts established paradigms and sparks a promising new chapter in advanced materials science and engineering.

High-entropy alloys challenge traditional paradigms of alloy composition. Historically, alloys have been optimized around one dominant element with a secondary component enhancing properties, such as strength or corrosion resistance. By contrast, HEAs leverage a complex cocktail of multiple elements, which intermix in a solid solution phase, generating materials with remarkable mechanical strength, corrosion resistance, and thermal stability. Yet, the atomic-scale arrangement of these elements, especially on surfaces where catalytic and mechanical properties are often governed, has remained an intractable puzzle.

The key to untangling this puzzle lies in understanding the concept of local chemical ordering—or the subtle, non-random arrangement of atoms within the otherwise disordered crystalline lattice. Although prior assumptions suggested some degree of local ordering, direct experimental evidence, especially at surfaces, has been conspicuously absent. This knowledge gap has thwarted efforts to precisely tailor surface properties, hampering innovations in sectors requiring materials that endure extreme environments, such as jet engines, nuclear reactors, and energy storage devices.

Kim’s research, conducted under the guidance of Professor TeYu Chien and in collaboration with a multidisciplinary team spanning several universities, sets a new standard for probing the atomic-scale surface chemistry of HEAs. Their focus centered on the well-studied CoCrFeMnNi system—a canonical high-entropy alloy known for its mechanical robustness and stability. The team employed an integrative approach combining surface-sensitive scanning tunneling microscopy (STM) with advanced computational density functional theory (DFT) simulations.

Scanning tunneling microscopy, renowned for its exceptional resolution, enabled the visualization of atomic arrangements on the alloy’s surface with quasi-long-range ordering. This means that while perfect periodicity was absent, discernible patterns in atomic distribution could be detected, challenging the prevailing notion of wholly random element placement. To refine these observations, Kim and colleagues applied DFT calculations, a quantum mechanical modeling method, which provided insights into the energetics and stability of specific atomic configurations within these quasi-ordered domains.

This dual-experimental and theoretical framework culminated in the first unequivocal observation and characterization of surface local chemical ordering in a high-entropy alloy. The implications are multifold: by correlating surface atomic organization with physical and chemical properties, scientists can now envisage engineering HEAs with tailor-made functionalities, be it enhancing catalytic activity for chemical processing or improving corrosion resistance for harsh operating environments.

“The revelation that surface local chemical ordering exists fundamentally shifts our understanding of HEAs,” explains Professor Chien. “It means that by manipulating this order, we gain a powerful lever to control surface properties—a breakthrough that had previously been out of reach due to limitations in detection technologies.”

This advancement is not only a triumph of instrumental innovation but also of international collaboration. The project synergized expertise from the University of Wyoming, University of New Haven, University of Tennessee-Knoxville, and Taiwanese institutions National Yang Ming Chiao Tung University and National Tsing Hua University. Among the notable contributors is Jien-Wei Yeh, a pioneer who first demonstrated the stability of high-entropy alloys over two decades ago, signifying the lineage and evolution of HEA research.

Beyond academic merit, the practical applications of this insight could be transformative. With precise control over atomic-scale surface arrangements, materials scientists can devise alloys that do not just meet but exceed the rigors of future technologies. Imagine turbine blades in jet engines that maintain integrity at higher temperatures, or battery components with enhanced durability and efficiency due to optimized surface catalytic reactions.

This research was facilitated by funding from the U.S. National Science Foundation and the Air Force Office of Scientific Research, underscoring the strategic importance of materials innovation in national scientific agendas. The findings were recently published in the prestigious journal Nature Communications, signaling high recognition by the broader scientific community.

Kim’s methodology includes mapping surface atoms, detecting disparities in elemental distribution, and modeling their energetic preferences using DFT calculations. This hybrid approach overcomes prior technical hurdles, such as distinguishing neighboring atoms of similar atomic numbers, and surpasses earlier indirect inference techniques that could not definitively prove local chemical order.

Looking ahead, this breakthrough opens avenues for systematic exploration of surface phenomena across other HEAs, potentially unraveling new physical principles governing alloy behavior at the nanoscale. Moreover, it suggests that entropy, traditionally viewed as a measure of disorder, might be harnessed in a nuanced manner to design materials that balance order and randomness for exceptional performance.

In summary, the direct visualization of surface local chemical ordering in HEAs marks a pivotal moment in materials science. It bridges a critical knowledge gap, delivers a versatile analytical toolkit, and lays the groundwork for designing next-generation alloys tailored at the atomic level. As industries push the boundaries of performance and durability, these advances will doubtlessly play a central role in shaping the materials of the future.

Globally, PET is one of the most widely used plastics, with over 500 billion single-use beverage bottles produced annually. This mammoth production volume leads to a staggering accumulation of plastic waste, much of which ends up in landfills, exacerbating ecological degradation. The urgency to address this mounting environmental challenge has spurred researchers to rethink PET’s lifecycle, focusing on advanced recycling techniques that can reinvent its value beyond single-use applications. The research team, helmed by Yun Hang Hu, showcases a promising pathway by converting this vast reservoir of plastic waste into functional carbon-based components for supercapacitors.

Supercapacitors are vital energy storage devices, known for their ability to rapidly store and release energy through electrical double-layer capacitance, making them indispensable in a variety of fields such as transportation, consumer electronics, and industrial systems. Unlike batteries, supercapacitors rely on highly conductive carbon electrodes to deliver repeated quick bursts of high power. Key to their performance are the porous carbon electrodes and the separator films that modulate electrolyte flow and electrical isolation within the device. By leveraging PET waste, Hu and colleagues have crafted an all-plastic supercapacitor that rivals, and in some metrics surpasses, devices assembled using conventional glass fiber separators.

The team introduced two distinct heat-based fabrication methods to upcycle PET into supercapacitor components, effectively reimagining waste plastic at the molecular level. First, bottle fragments were finely chopped into couscous-sized grains and mixed with calcium hydroxide before being pyrolyzed at approximately 700 degrees Celsius under vacuum. This thermal treatment induced carbonization of PET, resulting in a porous, electrically conductive carbon powder ideal for supercapacitor electrode fabrication. The carbon powder was subsequently blended with carbon black and a polymer binder to produce uniform, thin electrode sheets through controlled drying.

For the separator film, a different physical transformation was employed. Small pieces of PET, comparable in size to postage stamps, were flattened and meticulously perforated with hot needles. This process created an optimized porous pattern enabling efficient ionic conduction through the electrolyte while preserving electrical insulation between electrodes. The perforated PET separator thus served as a resilient, lightweight alternative to traditional glass fiber membranes, contributing to a fully plastic-based device architecture.

In assembling the supercapacitor, researchers sandwiched two porous carbon electrodes, fabricated from upcycled PET, within a potassium hydroxide electrolyte medium. The perforated PET film was positioned between the electrodes to prevent short circuits while allowing ionic flow. Performance testing revealed that the upcycled supercapacitor retained an impressive 79% of its initial capacitance after cyclic operation. Intriguingly, this retention rate slightly surpassed that of a comparable device incorporating a glass fiber separator, which exhibited a 78% capacitance retention, underscoring the efficacy of the all-plastic design.

The implications of this research extend beyond the laboratory, heralding opportunities for circular energy storage solutions that transform post-consumer plastic waste into valuable, high-performance components. Beyond environmental benefits, the cost efficiency of producing fully plastic supercapacitors is notable. PET-based devices are less expensive than those utilizing glass fiber separators, reducing manufacturing expenses while maintaining recyclability. This confluence of economic and ecological advantages signals a vital step toward sustainable energy storage technologies that align with global efforts to reduce plastic pollution.

Looking forward, the team envisions further optimization of the fabrication processes and material properties to unlock the full potential of PET-derived supercapacitors. Refinements in carbonization parameters, electrode architecture, and separator porosity could elevate device capacitance, cycling stability, and overall energy density. Hu optimistically forecasts that within five to ten years, these upcycled supercapacitors could transition from experimental prototypes to commercially viable energy storage solutions, particularly as demand for sustainable, recyclable technologies escalates worldwide.

The innovative use of calcium hydroxide during pyrolysis is especially noteworthy, as it facilitates the creation of a porous carbon structure essential for effective electrode performance. The porous morphology increases surface area accessible to ions, a critical factor for enhancing charge storage capacity. This strategy exemplifies how chemical additives during thermal conversion can tune the electrochemical characteristics of carbon materials derived from plastic waste, thereby bridging environmental remediation with cutting-edge materials engineering.

The research also underscores the versatility of PET as a precursor material for energy applications beyond its conventional uses. By manipulating its molecular backbone through controlled thermal and chemical processes, PET not only sheds its harmful waste identity but gains functional superiority in energy storage devices. This shift redefines the lifecycle of plastics, emphasizing resource efficiency and circular economy principles within the chemical and materials sciences.

Moreover, the mechanical robustness and recyclability of the perforated PET separator represent a tangible improvement over glass fiber alternatives. Traditional glass fiber separators, while effective, pose challenges in waste handling and cost. The all-plastic separator is not only lighter but also easier to recycle alongside the electrodes, further streamlining end-of-life processing. Such integration of material design and sustainability facilitates more eco-conscious manufacturing of energy devices.

In sum, this pioneering research opens transformative pathways where abundant plastic waste is harnessed to meet burgeoning energy storage needs. The confluence of environmental stewardship, material innovation, and functional performance outlined in this study exemplifies the future trajectory of green energy technologies. As society grapples with plastic pollution and the imperative for sustainable energy systems, PET-derived supercapacitors stand as a beacon of scientific ingenuity and hope.

Hexagonal diamond, also known as lonsdaleite after the pioneering scientist who first identified it in meteorite samples, differs fundamentally from cubic diamond in its crystal lattice structure. While cubic diamond exhibits a face-centered cubic lattice configuration, hexagonal diamond crystallizes in a hexagonal lattice, which theoretically imparts enhanced hardness, potentially greater thermal conductivity, and unique electronic properties. These distinctions make HD an ideal target for next-generation quantum materials and ultra-hard coatings, but challenges in synthesizing bulk, pure samples have constrained past investigations to nanometer-scale, defective, or heterogeneous composites.

Previous attempts to isolate hexagonal diamond have primarily encountered a persistent obstacle: the resulting samples have invariably been highly disordered and embedded within mixtures of graphite, cubic diamond, and other carbonaceous structures. Such contamination and structural heterogeneity have precluded definitive characterization of HD’s bulk properties and obstructed its recognition as a bona fide crystalline phase. This longstanding issue has relegated insights into HD’s potential largely to theoretical predictions and indirect observations, fostering a scientific mystery that has lingered for decades.

The breakthrough reported by Yang and colleagues fundamentally addresses this challenge. Utilizing pristine graphite single crystals as the precursor material, the researchers applied precisely controlled quasi-hydrostatic conditions combining compression and elevated temperatures. This carefully optimized high pressure–temperature (P–T) regime facilitated a phase transformation yielding large, three-dimensional HD crystals, ranging from 100 micrometers to millimeter scale. Such scale and crystallographic quality are unprecedented for synthetically derived hexagonal diamond, enabling detailed structural and physical analyses that have been previously unattainable.

A particularly striking aspect of the synthesis process is the observed orientation-dependent transformation between graphite and hexagonal diamond layers. The team demonstrated direct conversion of graphite oriented along the (10\bar{1}0) lattice planes into hexagonal diamond’s (0002) planes, as well as transformation in the reverse orientation, from graphite (0002) to HD (10\bar{1}0) planes. This controlled epitaxial relationship indicates a nuanced atomic reconfiguration mechanism where interlayer bonding in graphite is reorganized to produce the characteristic hexagonal diamond structure.

At the microscopic level, the hexagonal diamond bulk sample is composed of tightly intergrown nanocrystals approximately 100 nanometers in size, organized into a complex threefold intergrowth network. This microstructural architecture appears predominantly as hexagonal diamond, though trace amounts of cubic diamond imperfections are present. Such minor inclusions are unlikely to detract materially from the bulk properties of HD, and instead reflect the inevitable intricacies of solid-state transformations under extreme synthesis conditions.

Crucial insights were gained regarding the bonding characteristics within the hexagonal diamond lattice. The newly formed interlayer covalent bonds in HD are notably shortened relative to the intralayer bonds, leading to a more compact and optimized structural arrangement. This refined bonding framework undergirds many of the anticipated mechanical and electronic properties of HD, distinguishing it clearly from its cubic counterpart despite their shared carbon composition.

Contrary to long-standing assumptions that hexagonal diamond would exhibit dramatically superior hardness compared to cubic diamond, the researchers discovered that the hardness of HD is only marginally higher. This finding challenges prevailing theoretical models and underscores the importance of experimentally derived data in refining our understanding of carbon-based superhard materials. It suggests that other properties, such as thermal or electronic behavior, might offer more compelling advantages in future technological applications.

The implications of successfully producing bulk hexagonal diamond extend far beyond academic curiosity. The ability to generate high-quality HD crystals in macroscopic quantities will empower materials scientists to systematically investigate its physical, chemical, and mechanical properties, leading to potential applications in cutting-edge electronics, quantum computing substrates, and industrial-grade cutting or abrasion tools. Additionally, the insights garnered from the synthesis methodology itself provide a blueprint for fabricating other exotic carbon allotropes under controlled conditions.

Looking ahead, the research team emphasizes that further refinement of precursor graphite purity and fine-tuning of the high pressure–temperature parameters could yield hexagonal diamonds of even higher crystalline perfection. Such improvements could enhance the performance attributes and unlock a fuller suite of unique properties predicted for this elusive allotrope. The progress demonstrated suggests that the era of exploring hexagonal diamond’s true potential is finally within reach.

This landmark achievement underscores the importance of perseverance and innovation in materials science. After more than half a century of partial successes and ambiguous results, the clear identification and characterization of bulk hexagonal diamond crystallizes years of incremental progress and technical ingenuity. By bridging the gap between theoretical promise and practical realization, Yang, Lau, and their collaborators have reshaped the foundational understanding of carbon polymorphs.

As investigations proceed, a new chapter is opening in the quest to harness carbon’s versatile chemistry for transformative technologies. Beyond cubic diamond, the novel properties and applications enabled by bulk hexagonal diamond may well redefine standards of hardness, thermal management, and quantum coherence. Continued interdisciplinary collaboration among physicists, chemists, and engineers will be paramount in translating this discovery from the laboratory bench to real-world innovations.

Science Magazine readers can anticipate a surge of riveting research building upon this foundation, alongside intriguing discoveries about hexagonal diamond’s unique interactions with light, electrons, and phonons. Such knowledge will be critical in tailoring this material for specialized purposes in optoelectronics, spintronics, and nanoscale devices. The revelation of bulk hexagonal diamond invites a bold reexamination of carbon’s allotropes and a renewed enthusiasm for pushing the boundaries of what synthetic materials can achieve.

In conclusion, the synthesis of bulk hexagonal diamond marks a watershed moment in materials science with far-reaching implications. The work offers a tangible demonstration that decades-old scientific puzzles can be unraveled through meticulous experimental design and cutting-edge techniques. As the story of hexagonal diamond unfolds in unprecedented detail, the scientific community stands poised to unlock extraordinary functionalities from one of nature’s most versatile elements.
