Nano-cavities are made up of an orderly series of tiny, interconnected molecules that essentially reflect, or circulate, light. Gan already has shown that his nano-cavity structures increase the ...

Vertical cavity surface emitting lasers, or VCSELs, are among the most widely used laser sources today, powering applications from data communications to consumer products such as optical mice and ...

Raman and infrared spectroscopies are important tools for chemical analysis at the molecular level, providing key information such as the chemical bonding of a system to be measured. However, Raman ...

An international team of researchers has developed a completely new type of drug carrier for targeted delivery to the sick organ -- the gel nano-capsules with a double shell. By now, the research is ...
