Differentiating Test Frequency and Self‐Heating Effects on the Fatigue Behavior of Normalized SAE 1045 Steel by In Situ Multisensor Monitoring

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT In this research, the fatigue behavior of a normalized SAE 1045 (C45E, 1.1191) steel was investigated at test frequencies between 5 and 260 Hz. The focus was on differentiating between frequency‐induced lifetime extension and lifetime‐reducing self‐heating phenomena.

Dual asymmetric centrifugation to prepare cosmetic emulsions and creams: Physico‐chemical and energy considerations

International Journal of Cosmetic Science, EarlyView.
Dual asymmetric centrifugation (DAC) enables the preparation of stable cosmetic emulsions and structured creams with physicochemical, rheological and textural properties comparable to those of conventional processes. At larger scales, DAC also offers competitive energy efficiency by avoiding heating steps, supporting more sustainable cosmetic ...

Variably shock‐compacted chondrites: Deformation–thermal histories, large differences in mineral deformation response, and implications for lithification

Meteoritics &Planetary Science, EarlyView.
Abstract Eight different H, L, and LL chondrites with 11 lithologies were studied and show good evidence for progressive shock effects and compaction. In weakly shocked chondrites (Baszkόwka, Bjurböle, Saratov, NWA 7298 Lithology A and C), silicates were dominantly fractured, troilite and metal were more deformed than olivine and fluidized, and ...

Chondrule size averaging in two and three dimensions

Meteoritics &Planetary Science, EarlyView.
Abstract Chondrule sizes are an important discriminant of chondrite groups and chondrule formation theories. Yet most studies report 2‐D sizes without attempting the somewhat tedious corrections to 3‐D proposed in the past literature. I show here that 3‐D size averages can be simply calculated directly from 2‐D averages of appropriate powers of sizes ...

Distribution and rare earth element abundances of apatite in Bennu samples determined by synchrotron X‐ray fluorescence spectroscopy

Meteoritics &Planetary Science, EarlyView.
Abstract Apatite is often the most rare earth element (REE)‐enriched mineral in chondritic meteorites. REE enrichment and fractionation levels in apatite grains can give insight into the aqueous fluids in which they formed and the conditions prevailing within the host body. In this study, we applied synchrotron X‐ray fluorescence (SXRF) spectroscopy to
