Static and Dynamic Analysis of Porous Gas Bearings Lubricated With Air, Refrigerant R‐134a, Helium and Hydrogen

Lubrication Science, Volume 38, Issue 5, Page 301-326, August 2026.
ABSTRACT Porous gas bearings (PGBs) enable high‐speed, oil‐free operation in modern rotating machinery. This study develops a coupled thermo‐hydrodynamic (THD) model for a cylindrical porous gas bearing lubricated with four working fluids—air, R‐134a, helium and hydrogen.

UV‐Assisted Direct Ink Writing of Fully Bio‐Derived Photopolymer Composites With High Cellulose Loadings

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
Fully bio‐based, cellulose‐reinforced inks are developed to 3D print structures via UV‐assisted extrusion. The inks flow easily during printing and solidify rapidly under light, enabling stable shapes and improved performance. Post‐print treatment allows tuning of strength and stiffness, demonstrating a sustainable route toward functional, plant‐based ...

SPH Modelling of Hydrodynamic Lubrication along Rough Surfaces

Lubricants, 2019
Rough and textured surfaces are of paramount importance for lubrication, both in nature and in technology. While surface roughness relevantly influences both friction and wear, artificial surface texturing improves the performance of slider bearings as ...

Microplastics Toxicity and Life‐Threatening Impact on the Arabian Gulf: A Critical Review

Environmental Quality Management, Volume 36, Issue 2, August 2026.
ABSTRACT Microplastics (MPs) have emerged as a pervasive pollutant in marine environments worldwide, yet the Arabian Gulf remains underrepresented in global assessments despite its ecological and economic significance. The estimated mass of MPs entering the water of the Gulf ranged from 155 to 413.4 kt per year.

Dynamic Evolution of Forearc Subsidence Controlled by Slab Geometry

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Several subduction zones worldwide present an enigmatic forearc topography and strain characterized by extension at a forearc ridge near the trench and shortening within a forearc valley located between the ridge and the magmatic arc. The development of this topography has been linked to progressive slab steepening, while strain patterns ...

Efficiency of Superplasticizers in Low‐carbon Alkali‐activated Slag–Silica Fume Binders Governed by Polymer Solubility

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
ABSTRACT Workability control of alkali‐activated binders (AABs) remains an obstacle to producing low‐carbon clinkerless ultra‐high‐performance concrete, as their formulation usually necessitates low water‐to‐binder (W/B) ratios, high binder content, and concentrated activator solutions. To address this challenge, a greener and more manageable composite

Distinct Temporal Mouthfeel in Dairy and Plant‐Based Milk Is Related to Their Rheological and Tribological Spectra

Journal of Texture Studies, Volume 57, Issue 4, August 2026.
Integrating microstructure, rheology, and tribology with sensory evaluation methods that capture dynamic changes in mouthfeel perception provides new insights into the gaps in sensory performance between plant‐based and conventional dairy products. ABSTRACT Despite an expanding market for plant‐based milks (PBMs), replicating the techno‐functional ...

Protein kinase Cδ and pharmacomechanical coupling: Re‐envisioning cerebral vascular control

The Journal of Physiology, Volume 604, Issue 15, Page 6324-6347, 1 August 2026.
Abstract figure legend Top, G‐protein coupled receptors trigger electromechanical and pharmacomechanical coupling, the latter via signal transduction pathways that inhibit myosin light chain phosphatase. Middle, the relative contribution of electromechanical and pharmacomechanical coupling varies with the concentration and the vessel area to which ...
