Abstract Imaging facilities underpin a growing share of modern life‐science research, yet the career conditions and scholarly recognition of the Imaging Scientists in core facilities who design, deliver, and interpret imaging research remain uneven. This mismatch has previously been shown to risk loss of expertise, reduced service quality, and weaken ...

Abstract Purpose To investigate the effects of the elemental composition and the manufacturing process of cobalt chromium–molybdenum (CoCr–Mo), cobalt chromium–tungsten (CoCr–W), and CoCr–Mo‐W alloys on metal–ceramic bond strength. Materials and Methods Six CoCr‐based alloys were included in this study, a were classified into three different groups ...

Abstract Purpose This study aims to evaluate the effects of adding titanium dioxide (TiO2) nanotubes (NTs) to three‐dimensional (3D) printed denture base resin on the thermal and thermomechanical properties, which have high clinical relevance. Materials and Methods TiO2 NTs with dimensions of 30–70 nm in diameter and 2–4 µm in length were added to the ...

Abstract We report new results from a study of shock‐related features in the L6 ordinary chondrites Northwest Africa (NWA) 4672 and NWA 12841. Our observations confirm the occurrence of eight high‐pressure (HP) minerals in each meteorite, namely, ringwoodite, majorite, akimotoite, wadsleyite, albitic jadeite, lingunite, tuite, and xieite.

Abstract The framework of the Impact Cratering Committee (ICC) of the Meteoritical Society was approved in 2020, with the first committee members appointed in 2023. The ICC has a mandate to (1) approve, maintain, and update a database of confirmed terrestrial meteorite impact structures, (2) define and regularly update the criteria used for ...

Could a complete solid solution between Aikinite and Bismuthinite exist?
During the study of polymetallic sulphide veins in Bulancak (Giresun, Turkey) the presence of aikinite (Cu Pb BiS3) was identified by means of x-ray diffraction, optical studies, and electron probe microanalysis methods.

Abstract Asteroid compositional analysis relies on comparing reflectance spectra with laboratory data from well‐characterized meteorites. To advance this comparison, we performed a comprehensive laboratory analysis on a slab of the Northwest Africa (NWA) 7317—CR6 carbonaceous chondrite.
