Japanese Research Team Uses LEDs to Oxidize Plastic

Using LED as a light source, researchers at Osaka University have now developed a convenient light-driven process for oxidizing polypropylene (PP) without harmful waste. The research team used radicals to make the plastic react. Scholars chose an LED lamp as the light source photo-chemically activate radicals for breaking down the chemical bonds which make plastic unreactive and hard to decompose. "In applications like printing and medical materials, plastics must be surface-modified," explained Tsuyoshi Inoue, co-author of the study. "Oxidizing C-H bo...

Japanese Researchers Find Cholesteric Liquid Crystals Open New Route to Planar Optical Elements

Researchers at Osaka University developed a technology to control the light wavefront reflected from a cholesteric liquid crystal - a liquid crystal phase with a helical structure. Although known for their ability to Bragg-reflect light, cholesteric liquid crystals could only be used as flat mirrors, reflecting light at the same angle as the incident angle. The new technology enables planar optical components to be made with functionality by design, contributing to the miniaturization of catoptrics devices.
