Lab-on-chip  is an integrated miniaturized device  that  allows researchers to perform all the operations  from sample collection to final analysis onto the same chip. Theoretically, LOC technology has the potential to carry out almost any laboratory procedure on a miniaturized scale. This could range from DNA sequencing and biochemical detection …

Tungsten is one of the hardest metals on the earth, and many scientists compare it to diamond. Tungsten is a dull silver-colored metal with the highest melting point of any pure metal. Pure tungsten melts at a whopping 6,192 degrees F (3,422 degrees C) and won’t boil until temperatures reach …

Optical communications make use of light waves, very high frequency (100 terahertz) electromagnetic waves, for information transmission. Modern optical communications were begun in the 1960s, when lasers were invented as a coherent light source. Since then, the rapid development of photonic technologies has made possible optical communication links with a …
