Ultrathin lead-free piezoelectric films break the nanoscale thickness barrier

Mar 17, 2026 Engineered multilayer bismuth ferrite films achieve piezoelectric performance four times higher than conventional forms at just nanometers thick. (Nanowerk News) Researchers have engineered ultrathin films of bismuth ferrite (BiFeO3) that deliver a piezoelectric response more than four times greater than the material's conventional form, removing a critical...

Custom-made concrete from a 3D printer

Mar 17, 2026 Instead of using more and more concrete and steel, a research team is focusing on intelligent shapes, digital manufacturing, and alternative binders. The aim is to create a climate-friendly building material that is delicate yet stable and can be custom-made using 3D printing, dismantled, and reused. (Nanowerk...

New experiments reveal what makes metals transparent to visible light

Mar 16, 2026 Researchers experimentally confirm their 2021 hypothesis that electron-phonon coupling, not electron-electron interactions, explains why some metallic oxides are transparent. (Nanowerk News) Researchers from the Institute of Materials Science of Barcelona (ICMAB-CSIC) Gyanendra Singh and Josep Fontcuberta (MULFOX group) have experimentally confirmed a theory they proposed in 2021...

Single growth technique dopes atomically thin MoS2 with over 40 different elements

Mar 16, 2026 MoS2 monolayers doped across the periodic table show p-type, n-type, metallic, and magnetic behavior, providing building blocks for all-MoS2 device integration. (Nanowerk Spotlight) Among the many techniques that make modern processors possible, doping is one of the most fundamental. By introducing trace impurity atoms into a semiconductor,...
