Three-dimensional bitwise optical recording with a density of 500 Gb/cm3 in fused silica using a Ti:sapphire femtosecond laser modulated by binary digits is dem
In natural gabbro, the natural nonlinear oscillation of medi-scopic scale can be observed under the normal temperature and pressure. A process of complex form c
An active cooling solution based on close-looped micro impinging jet is proposed for high power light emitting diodes (LEDs). In this system, a micro pump is ut
