Scientists explore the strategies of defects and nanostructure fabrication for promoting piezocatalytic activity
As an important chemical raw material, hydrogen peroxide (H2O2) is widely applied in various aspects of industry and life. The industrial anthraquinone method for H2O2 production has the serious flaws, such as high pollution and energy consumption. B.....»»
Bots dominate internet activity, account for nearly half of all traffic
49.6% of all internet traffic came from bots in 2023, a 2% increase over the previous year, and the highest level Imperva has reported since it began monitoring automated traffic in 2013. For the fifth consecutive year, the proportion of web traffic.....»»
NASA to hoist its sail: Solar sail mission gets ready for launch
A NASA mission testing a new way of navigating our solar system is ready to hoist its sail into space—not to catch the wind, but the propulsive power of sunlight. The Advanced Composite Solar Sail System is targeting launch on Tuesday, April 23 (We.....»»
Saturn"s ocean moon Enceladus could support life—researchers are working out how to detect extraterrestrial cells there
Saturn has 146 confirmed moons—more than any other planet in the solar system—but one called Enceladus stands out. It appears to have the ingredients for life......»»
NASA observations find what helps heat roots of "moss" on sun
Did you know the sun has moss? Due to its resemblance to the earthly plants, scientists have named a small-scale, bright, patchy structure made of plasma in the solar atmosphere "moss." This moss, which was first identified in 1999 by NASA's TRACE mi.....»»
