This video from CBS New York showcases a self-moving Nitinol robot that could one day be used inside a human body.
Into another dimension: Nanoscale trilayer exhibits ultrafast charge transfer in semiconductor materials
Advancements in optoelectronic semiconductor technology are heavily reliant on the controlled movement of charges and excitons—pairs of electrons and holes—towards specific directions to generate fuel or electricity. Mirroring the mechanism of photosynthesis, where pigments capture solar energy and funnel it to a reaction center for conversion and utilization, photons in this process create electron-hole pairs. […]
Single-crystal cathodes for faster-charging, longer-lasting EVs
A team at Pohang University of Science and Technology has unveiled a groundbreaking single-crystal synthesis technique. This innovation significantly boosts the resilience of cathode materials, a key component in electric vehicle batteries. Professor Kyu-Young Park from the Graduate Institute of Ferrous & Eco Materials Technology and the Department of Materials Science and Engineering, along with PhD […]
A Dune-inspired spacesuit turns astronaut pee into drinking water
In the iconic sci-fi saga Dune, the inhabitants of the parched world of Arrakis don unique garments known as stillsuits to reclaim their body’s water. Drawing inspiration from this concept, engineers have developed an innovative prototype spacesuit that transforms astronauts’ urine into potable water. Presently, astronauts don a maximum absorbency garment, akin to a sophisticated […]
New technique enables ultrafast imaging of light-matter interactions
Scientists at the SLAC National Accelerator Laboratory, part of the Department of Energy, have uncovered novel properties in an ultrathin material that could revolutionize the way we handle light. This breakthrough is anticipated to benefit optoelectronic devices—those that sense, modulate, or produce light—as well as advance our understanding of light polarization within substances. These insights […]
