High efficiency solar conversion requires collection of a broad spectrum of wavelengths from the ultra-violet into the infrared. Solar collector mirrors must provide high reflection across this spectral band without degrading over time. This work pre

Interference filters have improved over the years. Sharp spectral edges (> 1 db/nm) reach high optical density (OD > 8) in a few nm. In-situ optical monitoring to within 0.1% error enables these levels of performance. Due to limitations related to f-

Alpha smooth muscle actin (alpha-SMA) was recently shown to be present in mouse subcutaneous tissue fibroblasts in the absence of tissue injury. In this study, we used a combination of immunohistochemistry and correlative confocal scanning laser and
