Grease Film Behavior in Ball Bearings
LubricantsTo the film thicknesses of grease-lubricated ball bearings, the viscosity of the base oil is considered in the Elastohydrodynamic Lubrication (EHL) equations. For very low speeds, the grease film thickness is much larger than the calculated base oil film

Elasticity Improvement and Water Loss Prevention in Vulvar Skin by Topical Nonhormonal Moisturizer
JEADV Clinical Practice, EarlyView.ABSTRACT Background Postmenopausal vulvovaginal symptoms due to estrogen depletion are very common. Many women prefer over‐the‐counter (OTC), Nonhormonal products containing few or no additives. Objectives We investigated the effect of a topical Nonhormonal moisturizer containing just mineral oil, white beeswax, emollients, and water.

Macromolecular Materials and Engineering, EarlyView.This study explores the effects of DNOP plasticizer on P(VDF‐TrFE‐CFE) terpolymers, revealing a strong synergy between chemical structure and physical properties. High TrFE bringing natural flexibility and CFE enhancing the plasticizer retention through theorized halogen bonds, ultra‐soft, crack‐free films of high permittivity and softness are ...

Poly(sarcosine) Lipid Synthesis From CO2‐Based Sarcosine‐N‐Carboxyanhydride
Macromolecular Rapid Communications, EarlyView.In this work, we optimize and scale‐up a CO2‐based synthesis of sarcosine‐N‐carboxyanhydride (Sar‐NCA) to the gram scale. The low toxicity and simplicity of the approach make it an attractive alternative to current toxic phosgene‐based approaches. The CO2‐based Sar‐NCA has sufficient purity for controlled polymerization.

Movement Disorders, EarlyView.Variants in GBA1, the gene encoding the lysosomal enzyme glucocerebrosidase, cause Gaucher disease and confer an increased risk for parkinsonism. Strategies using small molecules can improve the function of glucocerebrosidase in lysosomes. A clear understanding of the mechanism‐of‐action of these compounds will facilitate development of GBA1‐modulating
