Visualizing biological cells under a microscope was just made clearer, thanks to a nanoparticle 'switch' that fluoresces to sharpen the resolution of microscopic images that depict small cellular structures.
Results reported this week confirm, for the first time, giant charge reversal for a surface in contact with a trivalent electrolyte solution. In contrast to previous observations, this did not require a highly charged surface.
Researchers describe the design and fabrication of fully biodegradable temperature sensors whose layout and ultrathin format confer a dynamic response of 10 ms and high mechanical stability, which is preserved even upon application of high strain load.
Researchers investigated why hafnium oxide based devices are so promising for memory applications and how the material can be tuned to perform at the desired level. This knowledge could be the base for future mass application in all kind of electronic devices.
