Chalcogenide glasses and glass-ceramics: Transparent

Indeed, monocrystalline germanium and polycrystalline ZnSe require shaping by polishing at the diamond tip, a long and expensive process. Moreover, the relatively easy synthesis of chalcogenide glasses allows a reduction in the production costs of IR optics. These strengths have recently led to various infrared optical applications such as night vision, detection of chemical and biological species,

Photosynthesis Lab Experiments , Sciencing

A simple lab experiment uses simple materials: scissors, glass jars, coffee filters, and acetone. Students cut up two or three large leaves (which need not be green). Mix the leaf pieces in acetone and let sit for a day. Cut the coffee filters into strips and dip one end into the acetone. As the plant chemicals released by the acetone move up the filter paper, a strip of green becomes visible, this is the chlorophyll.
