3D micro-/nanofabrication holds the key to build a large variety of micro-/nanoscale materials, structures, devices, and systems with unique properties that do not manifest in their 2D planar counterparts. Recently, scientists have explored some very different 3D fabrication strategies such as kirigami and origami that make use of the science of cutting and folding 2D materials/structures to create versatile 3D shapes. • Email to a friend • Researchers have demonstrated a facile synthesis of hollow-structured photocatalysts with controllable spatial location of active metals, chemical compositions and tunable shell thickness. • Email to a friend • Researchers have found a way to impart durable antiviral and antibacterial properties to an aluminum alloy used in hospitals. • Email to a friend • Distinct from traditional spin valves with a sandwich structure consisting of two ferromagnetic metals decoupled by the insertion of a non-magnetic spacer, recently, a research team has demonstrated two-state and three-state spin-valve effects using Fe3GeTe2 vdW homo-junctions without any spacer layer. Realization of multi spin states using the vdW interfaces could be important for non-volatile spintronic applications. • Email to a friend • Researchers visualized the formation of a solid electrolyte interphase on battery-grade carbonaceous electrode materials using in situ atomic force microscopy (AFM). This will help researchers design and build batteries with higher performance and durability. • Email to a friend • An international team of researchers has proposed a new way to test the structural stability of predicted 2D materials. The testing revealed a number of materials erroneously proposed earlier. The scholars believe that the use of the new method will further help to avoid mistakes in the development of two-dimensional nanomaterials that are in high demand in the modern world. • Email to a friend • More than 25 years since the discovery of superconductivity in strontium ruthanate (SRO), understanding the properties of this material remains as challenging as ever. Researchers now demonstrated that a SRO sample can allow the two energetically degenerate condensates of Cooper-pairs with opposite momentum to segregate in domains, with a domain wall in between where chirality changes. To use the analogy to Moses parting the sea, here the Red Sea would spontaneously part into 'magenta' and 'yellow' seas on either side. • Email to a friend • Scientists have developed a self-cleaning metallic surface that is structured with a laser process in such a way that water droplets no longer adhere and dirt particles can be removed from the surface. • Email to a friend • Experiments find the sweet spot for surface area and bubbles to store energy. • Email to a friend • For the first time, scientists have added microscopic tracking devices into the interior of cells, giving a peek into how development starts. • Email to a friend • Scientists are unraveling the properties of electricity-conducting plastics so they can be used in future energy-harvesting devices. • Email to a friend • |
