At short wavelengths, such as FUV, transparent, optically active materials are scarce. Reflection phase retardation by a multilayer thin film can be a good alternative in this wavelength region. We design a multilayer quarterwave retarder by calculating the electric fields at each boundary in the multilayer thin film. Using this method, we achieve designs of FUV multilayers which provide high, matched reflectances for both s- and p-polarization states, and at the same time a phase difference between ...

Alumina supported mono and bimetallic catalysts based on platinum and ruthenium were studied for the conversion of n-heptane at 400 and 500°C. The combustion of the 0.1 to 0.3 wt % of resulting carbonaceous deposits was followed by means of thermal programmed oxidation (TPO), that is by simultaneous quadrupole analysis of the oxygen consumption and the carbon dioxide evolution. No significant variation of the molecular ratio of oxygen consumed to carbon dioxide evolved was observed, either with the ...

ABSTRACT In the presence of trimethylamine N -oxide (TMAO), the TorS-TorR two-component regulatory system induces the torCAD operon, which encodes the TMAO respiratory system of Escherichia coli . The sensor protein TorS detects TMAO and transphosphorylates the response regulator TorR which, in turn, activates transcription of torCAD . The torR gene and the torCAD operon are divergently transcribed, and the short torR-torC intergenic region contains four direct repeats (the tor boxes) which proved to be ...

ABSTRACT Induction of the torCAD operon, encoding the trimethylamine N -oxide (TMAO) respiratory system, is tightly controlled by the TorS-TorR phosphorelay system in response to TMAO availability. TorS is an unorthodox sensor that contains three phosphorylation sites and transphosphorylates TorR via a four-step phosphorelay, His443→Asp723→His850→Asp(TorR). In this study, we provide genetic evidence that TorS can dephosphorylate phospho-TorR when TMAO is removed. Dephosphorylation probably occurs ...

We report the design and fabrication of multilayer reflective filters for the self-filtering cameras of a Ritchey-Chretien Lyman-a (Ly-a) telescope that uses reflecting multilayer mirrors, polarizers, and filters. The Ly-a telescope is designed to measure the linear polization of hydrogen Ly-a line (121.6 nm) emissions from the solar corona. A key element of the filter design includes the development of p multilayers optimized to provide maximum reflectance at 121.6 nm for the respective cameras without ...

New methods have been developed for the design of a far ultraviolet multilayer reflection polarizer and retarder. A MgF 2 /Al/MgF 2 three-layer structure deposited on a thick opaque Al film (substrate) is used for the design of polarizers and retarders. The induced transmission and absorption method is used for the design of a polarizer and layer-by-layer electric field calculation method is used for the design of a quarterwave retarder. In order to fabricate these designs in a conventional high vacuum ...
