The design and performance of an ultrahigh vacuum compatible soft X-ray double crystal monochromator at the Photon Factory in operation is described. This is a compact version of the JUMBO at SSRL with some improved mechanisms. Ge(111), InSb(111), α-quartz (10 1 0), beryl (10 1 0 and GGG(211) were tested as monochromatizing elements with regard to the resolution, intensity and radiation damage.read more

TL;DR: In this article, surface structures and electronic properties of submonolayer sulfur dioxide, SO2, molecularly adsorbed on Ni(111) and Ni(100) at ∼ 170 K have been investigated by means of S K-edge surface extended X-ray-absorption fine structure (SEXAFS), near-edge Xray absorption fine structure(NEXAFS) and S 1s X-Ray photoelectron spectroscopy (XPS) measurements.

TL;DR: In this article, the surface structures of submonolayer alkanethiol CH3(CH2)n−1SH (n=6,12) adsorbed on Cu(111) at room temperature (0.3 ML) were investigated by means of S K-edge surface extended X-ray absorption fine structure (EXAFS) and S, C-edge near-edge X-rays spectroscopies.

Effects of K-shell X-ray absorption of intracellular phosphorus on yeast cells.
TL;DR: The results strongly suggest that K-shell X-ray absorption in the resonance mode by cellular phosphorus atoms causes significantly more cellular effects than the off-resonance mode of absorption, probably via some specific changes induced in the phosphates of the DNA strand.
