Multi-notch holographic filters for atmospheric lines suppression

Near-infrared emission from atmospheric OH radicals is known to severely affect astronomical observations. Until now, only complex dispersive instruments were partially capable of removing this unwanted background, which is composed of hundreds of narrow e ...

Prediction of monochrome reflectance spectra with an extended Kubelka-Munk model

Roger Hersch, Patrick Emmel, Safer Mourad

We present a prediction model for digital printers and more specifically for electrophotographic devices. On the one hand, we propose an electrophotographic simulation model which estimates the microscopic structure of any printed toner layer based on its ...

Synchrotron radiation total reflection X-ray fluorescence and energy dispersive X-ray fluorescence analysis on AP1 (TM) films applied to the analysis of trace elements in metal alloys for the construction of nuclear reactor core components: a comparison

Synchrotron radiation induced total reflection X-ray fluorescence (TXRF) and conventional 45 degrees energy dispersive X-ray fluorescence analysis (EDXRF) using a 150-nm-thick AP1 (TM) film as sample carrier have been exploited for the elemental analysis o ...

An ultradense polymorph of rutile with seven-coordinated titanium from the Ries crater

Philippe Gillet

We report the discovery of an ultradense post-rutile polymorph of titanium dioxide in shocked gneisses of the Ries crater in Germany. The microscopic diagnostic feature is intense blue internal reflections in crossed polarizers in reflected light. X-ray di ...
