Journal of the American Oil Chemists' Society, EarlyView.ABSTRACT This work examines the crystallization, polymorphism, and mechanical properties of the stearin fraction of shea butter (Butyrospermum parkii) blended with two liquid diluents: rapeseed oil and octyldodecanol. Differential scanning calorimetry (DSC), X‐ray diffraction (XRD), texture analysis, and polarized light microscopy were used to assess ...

Journal of the American Oil Chemists' Society, EarlyView.ABSTRACT Fatty acid analysis is required in a wide range of industries, and conversion to fatty acid methyl esters followed by gas chromatography is by far the most common method of analysis. However, despite widespread use, there is no consensus on which derivatization method should be used or how the methods compare.

On the Post‐Curing Thermal Treatment of Silicone Rubbers: A Study on Electrical Performance
Journal of Applied Polymer Science, EarlyView.ABSTRACT Silicone rubbers, particularly poly(dimethylsiloxane) (PDMS), are popular across various industrial applications; however, notable issues arise from volatile cyclic siloxanes and their tendency to compromise performance. This study investigates the electrical performance (DC conductivity, dielectric spectroscopy, DC breakdown) of two ...

Journal of Applied Polymer Science, EarlyView.The graphical abstract presents a visual representation of the sequence of processes involved in the transformation of three distinct waste streams into recyclates. This is followed by a detailed examination of the granulate properties resulting from these processes.

Biodegradable Polyesteramide Films for Pervaporative Dehydration of Isopropanol–Water
Journal of Applied Polymer Science, EarlyView.ABSTRACT Polyesteramides are biodegradable polymers possessing good mechanical properties with potential applicability in membrane separations. In this work, polymer films from ε‐caprolactam and ε‐caprolactone‐based polyesteramides were prepared at a ratio of monomer units set so that the resulting copolymer had a low crystalline phase content.

Animal Research and One Health, EarlyView.Dietary selenium (Se) deficiency is recognized as a global problem, and exogenous Se supplementation can effectively enrich its levels in animal bodies. Offal tissues are equally important as meat in Se enrichment. Varying properties among Se species require information beyond total Se concentration to fully evaluate health risk/benefits.
