"Shear sound waves" provide the magic for linking ultrasound and magnetic waves
A team led by researchers from the RIKEN Center for Emergent Matter Science in Japan has succeeded in creating a strong coupling between two forms of waves—magnons and phonons—in a thin film. Importantly, they achieved this at room temperature, o.....»»
Atmospheric observations in China show rise in emissions of a potent greenhouse gas
To achieve the aspirational goal of the Paris Agreement on climate change—limiting the increase in global average surface temperature to 1.5 degrees Celsius above preindustrial levels—will require its 196 signatories to dramatically reduce their.....»»
Researchers find the more flood driving factors there are, the more extreme a flood is
There are several factors that play an important role in the development of floods: air temperature, soil moisture, snow depth, and the daily precipitation in the days before a flood. In order to better understand how individual factors contribute to.....»»
Team modulates electronic state of single-atom catalysts by CO molecular decoration for efficient methane conversion
Direct methane conversion has advantages such as low energy consumption, fewer processes, and better economics. However, it is difficult to activate methane at room temperature due to the high dissociation energy of C-H bonds of methane. Additionally.....»»
