Ion Beam Analysis of Microcrystalline Quartz Artifacts from the Reed Mound Site, Delaware County, Oklahoma

Description: This paper from the 23rd Conference on Application of Accelerators in Research and Industry conference proceedings evaluates the potential of particle induced X-ray emission spectrometry as a tool for future Ozarks chert provenance studies based on its ability to facilitate discrimination of Ozarks chert materials from different geological formations and identification of discrete groups of artifacts from the same geological formation.

Polymeric Coatings for Skutterudite-Based Thermoelectric Materials

Description: Article is a study with the main objective of mitigation of thermal degradation of skutterudite-based thermoelectric materials—so as to extend the service life of those materials and make them more attractive for industry from the economical perspective. Significant mitigation of oxidation and sublimation of thermoelectric (TE) materials was achieved.

Variability-Selected Low-Luminosity Active Galactic Nuclei in the 4 Ms Chandra Deep Field-South

Description: This article demonstrates that the observed variability cannot be explained by X-ray Binary populations or ultraluminous X-ray sources, so the variability is most likely caused by accretion onto a supermassive black hole.

Long-range current-induced spin accumulation in chiral crystals

Description: Article states that chiral materials, similarly to human hands, have distinguishable right-handed and left-handed enantiomers which may behave differently in response to external stimuli, so for the first time the authors use an approach based on the density functional theory (DFT)+PAOFLOW calculations to quantitatively estimate the so-called collinear Rashba–Edelstein effect (REE) that generates spin accumulation parallel to charge current and can manifest as chirality-dependent charge-to-spin… more
