A large stress-polishing machine and a large cryo-vacuum chamber have recently been built at the Laboratory of Astrophysics of Marseille to support major projects.
A photo-aligned, electrically-suppressed-helix ferroelectric liquid crystal enables high optical quality, shock stability, and low driving voltage, showing promise for application in future displays.
Microscopy curriculum stimulates STEM excitement
Success stories from teachers show that STEM curriculum using the scanning electron microscope excites their students and improves academic performance.
Novel combinations of polishing techniques on fused silica substrates produce super-polished mirrors with effective surface roughness of 0.25nm.
