Microbial Strategies for the Degradation of Spent Lubricating Oil: A Comparative Study of Isolate Bacterium and Consortium Cultures

open access: yesWater and Environment Journal, EarlyView.
This show the biodegradation of spent lubricating oil by Bacillus sp. and a marine bacterial consortium. The consortium showed higher growth, biosurfactant production and oil removal efficiency than the isolated strain, highlighting its potential for bioremediation ABSTRACT Spent automotive lubricating oil contains complex hydrocarbons and heavy metals,

Demonstration of beat‐to‐beat, on‐demand ATP synthesis in ventricular myocytes reveals sex‐specific mitochondrial and cytosolic dynamics

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Beat‐locked mitochondrial ATP transients reveal modular, sex‐specific bioenergetic control during excitation–contraction coupling. A, each action potential activates L‐type CaV1.2 channels, producing a Ca2+ influx that triggers ryanodine receptors (RyR2) and elicits SR Ca2+ release.

Environmentally Friendly Lubricants: The Role of Biopolymers in Modern Tribology

open access: yesSPE Polymers, Volume 7, Issue 3, July 2026.
Biomass‐derived biopolymers modified for green tribology applications with reduced friction, wear, and environmental footprint. ABSTRACT Energy losses due to friction and wear are a major challenge for the energy efficiency and sustainability of mechanical systems, motivating the development of green tribology strategies.

Processability and Crosslink Density: Role of Peptizers in Natural Rubber and Chlorobutyl Rubber

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 22, June 10, 2026.
This work evaluates how chemical and physical peptizers affect mastication, vulcanization behavior, and network formation in natural rubber and chlorobutyl rubber. Size‐exclusion chromatography, rheometry, DSC, and swelling analyses demonstrate improved processability but reduced crosslink density with peptizer addition.

Mass Transport of a Two Phase Flow Through a Converging Gap With One Moving Wall

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Mechanical seals are designed to separate two fluid phases from each other, exemplified by the separation of ambient air and hydraulic oil in hydraulic cylinder applications. These seals necessarily include a converging gap, even at a microscopic level.
