This idea has accumulated a consensus in the last 10 years, but no one has been able to measure vacuum friction. Enter the micro-scale silica gravitron, where the spinning particles could move fast enough to generate measurable vacuum friction for the first time. “Torque sensors are also widely used in studying small-scale magnetism ...
Nanoscale photocatalysts are small, man-made particles that harvest energy from sunlight to produce liquid fuels and other useful chemicals. But even within the same batch, the particles tend to vary widely in size, shape and surface composition. That makes it hard for researchers to tell what's really doing the work. A real-time imaging ...
Based on the coupling between near-field thermal radiation and MEMS thermal actuation, we presented the design and modeling of NanoThermoMechanical AND, OR, and NOT logic gates as an alternative, and showed their ability to be combined into a full thermal adder to perform complex operations. In this work, we introduce the fabrication and ...
By depositing two layers of platinum (SEM followed by FIB), the surface of the copper sample was protected from ion beam damage during FIB micromachining. The TEM foil was cut in the middle of the wear track, perpendicular to the sliding surface and parallel to the sliding direction. TEM foil preparation followed the procedure described by ...
After finding a new type of MEMS (microelectromechanical system) that allows better control, the researchers have used that knowledge to build an air-pressure sensor that could improve many everyday devices. "This is the same mechanism as devices we've designed in the past, but it's a different application," said principal investigator Shahrzad ...
