Rapid Identification of New Psychoactive Substances in Letters by LA‐APCI‐MS
Drug Testing and Analysis, EarlyView.Laser ablation coupled to molecular mass spectrometry utilizing a modified atmospheric pressure chemical ionization source was used for the detection of synthetic cannabinoid receptor agonists in infused prison mail samples. ABSTRACT New psychoactive substances (NPS), especially synthetic cannabinoid receptor agonists (SCRA), are increasingly smuggled ...

Geological Journal, EarlyView.Carbonates from Santos Basin revealed U–Pb ages correlated with basalt ages (A), suggesting that they were formed during magmatic events. These events placed hot CO2 in the reservoir, which, when mixed with carbonate‐rich cold water (B), led to thermal convection, enabling the formation of the U contained in the carbonates.

Weathering microenvironments on feldspar surfaces: implications for understanding fluid-mineral reactions in soils [PDF]
, 2008 The mechanisms by which coatings develop on weathered grain surfaces, and their potential impact on rates of fluid-mineral interaction, have been investigated by examining feldspars from a 1.1 ky old soil in the Glen Feshie chronosequence, Scottish ...

Unveiling the Crystal Structure of Sanidine: A Polarized Raman and Ab Initio Simulation Exploration
Journal of Raman Spectroscopy, EarlyView.This study combines polarized Raman spectroscopy and ab initio calculations to assign theoretical vibrational modes to observed spectra. Polarized Raman spectra were collected in six geometries (40–1200 cm−1). Theoretical predictions via DFT show good agreement with experiments, though some discrepancies point to influences like trace elements and ...

International Journal of Osteoarchaeology, EarlyView.ABSTRACT Sharp force trauma (SFT) is the main criterion used to identify chop mark butchery in zooarchaeology, yet its reliability as a diagnostic feature has not been systematically tested. Chop marks reflect both cutting and fracturing processes and exhibit characteristics of both sharp and blunt trauma.

Floating zone growth of high‐purity MgO substrate single crystals
Acta Crystallographica Section B, EarlyView.High‐purity MgO substrate crystals grown by the optical floating zone technique are demonstrated, which can serve as a foundation for the development of novel device concepts based on epitaxially grown thin films.MgO single crystals with diameters between 3.5 and 5 mm and lengths up to 40 mm were grown by the optical floating zone technique (OFZ ...
