CHAMPAIGN, Ill. — Millions of years of evolution have enabled some marine animals to grow complex protective shells composed of multiple layers that work together to dissipate physical stress. In a new study, engineers have found a way to mimic the behavior of this type of layered material, such as seashell nacre, by programming individual layers of synthetic material to work collaboratively under stress. The new material design is poised to enhance energy-absorbing systems such as wearable bandages and car…

Triboelectric nanogenerators (TENGs) are a transformative class of next-generation devices for energy conversion and self-powered sensing. Selecting appropriate triboelectric and conductive materials is crucial for optimizing TENG performance. In recent years, MXenes, especially Ti3C2 MXene, have become highly promising candidates for both triboelectric and conductive materials in TENGs. Although many studies (including research and review articles) have focused on TENG construction and performance, there is a significant gap in the literature: a comprehensive summary of MXene applications from a materials…

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…
