5+ hour, 10+ min ago  (775+ words) Published online by Cambridge University Press: 07 May 2026 where $\gamma = k_\parallel ^2 - \kappa _1$, and $\kappa _i = \omega ^2/c^2 K_i$. The speed of light in vacuum is $c$, the parallel and perpendicular components of the wave vector are $k_\parallel$, $k_\perp$, respectively, and the $i$ th…...

3+ hour, 59+ min ago  (386+ words) Chemists at Brown University have shown the first experimental evidence that carbon buckyballs, which launched the nanotechnology revolution, have a cousin made from 80 atoms of the element boron. The nanoscale world appears to have a new ball to kick around....

6+ hour, 39+ min ago  (165+ words) Some examples include the one-of-a-kind high-performance flexible frisbee made with BioCir® X, engineered for durability from bacterially fermented bioplastic and designed to break down across compost, soil, and marine environments without leaving any trace behind. While some projects can be…...

14+ hour, 28+ min ago  (301+ words) Verra has launched a public consultation for a major revision to its VM0044 methodology for Biochar Use in Soil and Non-Soil Applications in its Verified Carbon Standard (VCS) Program. The consultation period will run from July 15 through August 17, 2026. The revised methodology…...

21+ hour, 27+ min ago  (187+ words) Hydrogel materials possess unique physicochemical properties, including high water absorption, strong moisture retention, biocompatibility, tunable mechanical properties, environmental responsiveness, biodegradability, and a three-dimensional network structure. These characteristics endow them with significant practical value and broad application prospects in fields such…...

22+ hour, 33+ min ago  (177+ words) Researchers have designed a new porous organic anode material for more efficient lithium-ion batteries with improved energy storage capacity. As demand for energy storage for electric vehicles, smartphones, laptops, and renewable energy continues to grow, there is an increasing need…...
