A team of researchers affiliated with several institutions in China has developed a new process to produce well-aligned carbon nanotube (CNT) arrays on a 10-centimeter silicon wafer. In their paper published in the journal ...
In the past several decades, physicists have conducted deep laboratory investigations into nonlinear optics, plasma physics and quantum science using advanced high-intensity, ultrashort-pulse lasers. Increased use of the ...
Researchers at the Swiss Federal Institute of Technology Lausanne (EPFL) and IBM Research Europe recently demonstrated the laser cooling of a nanomechanical oscillator down to its zero-point energy (i.e., the point at which ...
If you even bother to think about friction at all, you might think about rubbing your hands together to warm them up.
