Mar 26, 2026 Outgassing jets may have stopped the comet's spin and restarted it in the opposite direction. (Nanowerk News) Astronomers using NASA’s Hubble Space Telescope have found evidence that the spinning of a small comet slowed and then reversed its direction of rotation, offering a dramatic example of how...

Mar 26, 2026 Spray-coated carbon flower sensors on stretchable substrates detect six biomarkers at sub-nanomolar levels and distinguish them in multi-analyte mixtures for wearable monitoring. (Nanowerk Spotlight) Electrochemical sensors that detect biological molecules generally face a trade-off. Simple carbon electrodes are cheap, stable, and easy to fabricate, but they struggle...

Mar 26, 2026 A new programmable metasurface performs dynamic beamforming and radar cross-section reduction across five frequency bands in a design 87% thinner than conventional approaches. (Nanowerk News) Researchers at Xidian University have developed a programmable metasurface that performs dynamic beamforming for communication while simultaneously reducing radar cross-section (RCS) across...

Mar 26, 2026 Researchers use field-resolved techniques to study how light interacts with nanocrystals, revealing ultrafast optical switching behavior on femtosecond timescales. (Nanowerk News) Just as an antenna interacts with radio waves, light interacts with metallic nanostructures. Therefore, understanding how a structure influences field oscillations provides valuable insights into the...

Mar 26, 2026 New carbon capture materials regenerate below 60 Celsius, low enough to use industrial waste heat, cutting the energy cost of the CO2 capture cycle. (Nanowerk News) Researchers at Chiba University have synthesized a new class of nitrogen-doped carbon materials called viciazites that can release captured carbon dioxide...

Mar 26, 2026 Researchers developed an air-breakdown triboelectric nanogenerator that harvests skin static electricity to power ultrathin keyboards and remote controls without batteries. (Nanowerk News) A team of engineers has developed a triboelectric nanogenerator that harvests the static electricity naturally present on human skin, producing enough power to operate keyboards,...

Mar 26, 2026 A new study has developed an innovative biochar-based nanomaterial that can rapidly remove harmful herbicides from soil while simultaneously protecting crops from contamination. The research offers a promising solution to one of agriculture's most persistent challenges: balancing soil remediation with food safety. (Nanowerk News) “Traditional methods often...

Mar 26, 2026 Researchers identify why graphene oxide selectively destroys bacteria while remaining safe for human cells, with applications from toothbrushes to sportswear. (Nanowerk News) A graphene-coated toothbrush has sold more than 10 million units on the strength of its antibacterial properties, but until now the precise mechanism behind that...

Mar 24, 2026 Researchers have uncovered the origin of polarity inversion, a long-standing phenomenon in polymer semiconductors that occurs only in certain materials. (Nanowerk News) A research team led by Prof. Boseok Kang at Sungkyunkwan University has uncovered the origin of polarity inversion—a long-standing phenomenon in polymer semiconductors that occurs...
