Auger Electron Spectroscopy of Free Argon Clusters
, 1996 Auger electron spectra and Auger yields of free argon clusm in the Ar(2p) excitation regime are reported. The Auger yield spectra show characteristic changes as a function of cluster size.

Optoelectronics of Single Mixed Dislocations in Van Der Waals Core‐Shell Nanowires
Small, EarlyView.Ge1‐xSnxS van der Waals core‐shell nanowires can host single helical dislocations whose character is tunable from a pure screw to a majority edge dislocation via the core‐shell lattice mismatch. Cathodoluminescence shows profound effects once an edge component is introduced, notably a lowering of the spontaneous emission quantum efficiency due to the ...

steel research international, EarlyView.This review explains how impurities from recycled scrap affect steel production and performance. Even small amounts (far below 1%) of these impurities can change how steel behaves during fabrication but also affect the properties of the end product. With better understanding and targeted countermeasures, these challenges can be managed, enabling wider ...

A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions
X-Ray Spectrometry, EarlyView.ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244Cm$$ {}^{244}\mathrm{Cm} $$ sources, and come with severe concerns on radiation safety and ...

X‐ray fluorescence microscopy exposure estimates using a single excitation energy
Journal of Synchrotron Radiation, EarlyView.We present calculations on the number of illuminating photons per pixel required for elemental detection using X‐ray fluorescence, even with far‐from‐threshold excitation.Scanning fluorescence X‐ray microscopy is widely used for quantitative mapping of elemental concentrations, including in studies of essential but low‐concentration metals in cells ...
