Tag: siliconSilicon sheets self-assemble into spheres to capture more light. Long-lived nuclear batteries powered by hydrogen isotopes are in testing for military applications. Nanowire anodes could let lithium-ion batteries run twice as long. Nanopatterns Improve Thin-Film Solar Cells Thin-film silicon solar cells are more efficient with tiny holes in the back electrical contact. IBM scientists are developing microchips for genome sequencing. An energy-efficient silicon device compresses light to make ultrafast signals. Longer-Running Electric-Car Batteries Silicon-nanotube electrodes may enable lithium-ion batteries to store 10 times more charge. Nano Ink Boost for Silicon Solar Inkjet-printed silicon increases solar-cell efficiency. Nanowire Advance for Lithium Batteries Electrodes made of carbon-silicon nanowires could boost the life and performance of lithium-ion batteries. Silicon Chip Spots Blood Proteins A microfluidic chip that integrates a light sensor detects blood proteins. Realizing Lithium-Battery Potential Nanoporous silicon that soaks up ions without self-destructing can make better batteries. Making Graphene More Practical A novel process yields big pieces of single-ply graphene for smaller, faster electronics. A new type of silicon promises cheaper, more-sensitive light detectors. Thin but efficient solar cells use one-tenth the silicon of conventional cells. Photovoltaics made of nanowires could lead to cheaper solar panels. |
