Researchers have a new low-cost method to carve delicate features onto semiconductor wafers using light -- and watch as it happens. The technique can monitor a semiconductor's surface as it is etched, ...

This study examines the relationship between enamel acid etch pattern and bond strength. Bond strength and etch patterns vary between tooth type and between teeth within a tooth type. An 'ideal' ...

Researchers developed a novel tunable ultrasonic liquid crystal light diffuser that allows changing the diffusion direction It is no mystery that light is essential to human life. Since the discovery ...
