Oxygen defect engineering enables efficient sulfone production using molecular oxygen at low temperature Sulfones, a class of sulfur-containing compounds, are chemically derived from the selective oxidation of sulfides. While these compounds form the core of the pharmaceuticals, solvents and polymer industries, their chemical synthesis is often hindered by high reaction temperatures and extreme reaction conditions. Additionally, these also require costly additives and harsh solvents for production. Against this backdrop, a team of researchers from Japan introduced a new catalyst design,…
TUM researchers develop new material for solid-state batteries The team led by Prof. Thomas F. Fässler from the Chair of Inorganic Chemistry with a Focus on Novel Materials partially replaced lithium in a lithium antimonide compound with the metal scandium. This creates specific gaps, so-called vacancies, in the crystal lattice of the conductor material. These gaps help the lithium ions to move more easily and faster, resulting in a new world record for ion conductivity. Since the measured conductivity far…
Iron-based magnetic nanomaterials have emerged as candidates in biomedicine due to their unique physicochemical properties. Beyond their established role as clinical MRI contrast agents, they have shown potential in drug delivery, magnetic hyperthermia, and the treatment of iron deficiency. Macrophages are also primary targets for these nanomaterials in vivo. The biological effects of iron-based nanomaterials are closely linked to the plasticity and phenotypic shifts of macrophages. However, the underlying mechanisms by which these materials influence macrophage-mediated immune regulation remain unclear….
Iron-rich hematite, commonly found in rocks and soil, turns out to have magnetic properties that make it a promising material for ultrafast next-generation computing In 2023, EPFL researchers succeeded in sending and storing data using charge-free magnetic waves called spin waves, rather than traditional electron flows. The team from the Lab of Nanoscale Magnetic Materials and Magnonics, led by Dirk Grundler, in the School of Engineering used radiofrequency signals to excite spin waves enough to reverse the magnetization state of…
Queensland University of Technology QUT researchers have identified a new material which could be used as a flexible semiconductor in wearable devices by using a technique that focuses on the manipulation of spaces between atoms in crystals. In a study published in the prestigious journal Nature Communication, the researchers used “vacancy engineering” to enhance the ability of an AgCu(Te, Se, S) semiconductor, which is an alloy made up of silver, copper, tellurium, selenium and sulphur, to convert body heat into…
The EFRE project G.O.A.L. (1.6-14) “Gallium Oxide Application Laboratory for Power Electronics”, which was launched in September 2024, completes the value chain created at the IKZ in the field of gallium oxide technology development. In addition to the existing Cz volume crystal growing and wafering sections, the epitaxy module in the form of a 3×2” MOVPE from AIXTRON has now been added. This expansion creates the prerequisite for establishing IKZ in the EU as the only supplier of 2 inch…
Imagine if phones never got hot no matter how many apps were running. Picture a future where supercomputers use less energy, electric cars charge faster, and life-saving medical devices stay cooler and last longer. In a study published in Nature Materials, a team of engineers at the University of Virginia and their collaborators revealed a radical new way to move heat, faster than ever before. Using a special kind of crystal called hexagonal boron nitride (hBN), they found a way…
To ensure the quality of recyclates, the Fraunhofer Institute for Structural Durability and System Reliability LBF is planning a new joint research project with partners from industry to optimize polyolefin recyclates for sustainable solutions. New analytical methods and user-friendly evaluation strategies should enable cost-efficient quality control and improvement of recycling processes. The project promotes the transformation to a circular economy and invites partners to collaborate. More information will be provided in a free online seminar on May 6, 2025. National…
Researchers have discovered antiferromagnetism in a real icosahedral quasicrystal, reinvigorating the search for antiferromagnetic quasicrystals Quasicrystals (QCs) are fascinating solid materials that exhibit an intriguing atomic arrangement. Unlike regular crystals, in which atomic arrangements have an ordered repeating pattern, QCs display long-range atomic order that is not periodic. Due to this ‘quasiperiodic’ nature, QCs have unconventional symmetries that are absent in conventional crystals. Since their Nobel Prize-winning discovery, condensed matter physics researchers have dedicated immense attention towards QCs, attempting to…
Lacquers, paint, concrete—and even ketchup or orange juice: Suspensions are widespread in industry and everyday life. By a suspension, materials scientists mean a liquid in which tiny, insoluble solid particles are evenly distributed. If the concentration of particles in such a mixture is very high, phenomena can be observed that contradict our everyday understanding of a liquid. For example, these so-called non-Newtonian fluids suddenly become more viscous when a strong force acts upon them. For a brief moment, the liquid…
Andrew Iams saw something strange while looking through his electron microscope. He was examining a sliver of a new aluminum alloy at the atomic scale, searching for the key to its strength, when he noticed that the atoms were arranged in an extremely unusual pattern. “That’s when I started to get excited,” said Iams, a materials research engineer, “because I thought I might be looking at a quasicrystal.” Not only did he find quasicrystals in this aluminum alloy, but he…

This…
Researchers can pull carbon directly from the air using changes in humidity, now with materials at a fraction of the cost EVANSTON, Ill. — Researchers at Northwestern University have expanded the potential of carbon capture technology that plucks CO2 directly from the air by demonstrating that there are multiple suitable and abundant materials that can facilitate direct air capture. In a paper to be published on Thursday (April 3) in the journal Environmental Science & Technology, the Northwestern researchers present…
Bilayer device can control many forms of polarized light Almost a decade ago, Harvard engineers unveiled the world’s first visible-spectrum metasurfaces – ultra-thin, flat devices patterned with nanoscale structures that could precisely control the behavior of light. A powerful alternative to traditional, bulky optical components, metasurfaces today enable compact, lightweight, multifunctional applications ranging from imaging systems and augmented reality to spectroscopy and communications. Now, researchers in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) are doubling down, literally, on metasurface…
Researchers have discovered an unexpected superconducting transition in extremely thin films of niobium diselenide (NbSe₂). Published in Nature Communications, they found that when these films become thinner than six atomic layers, superconductivity no longer spreads evenly throughout the material, but instead becomes confined to its surface. This discovery challenges previous assumptions and could have important implications for understanding superconductivity and developing advanced quantum technologies. Researchers at the Hebrew University of Jerusalem have made a surprising discovery about how superconductivity behaves…
A metamaterial with potential applications in sensor technology A flower-shaped structure only a few micrometres in size made of a nickel-iron alloy can concentrate and locally enhance magnetic fields. The size of the effect can be controlled by varying the geometry and number of ‘petals’. This magnetic metamaterial developed by Dr Anna Palau’s group at the Institut de Ciencia de Materials de Barcelona (ICMAB) in collaboration with her partners of the CHIST-ERA MetaMagIC project, has now been studied at BESSY…
