Weakening Processes in Carbonate‐Hosted Faults: Phyllosilicate Microlayers and Injections Along the Mattinata Fault (Southern Italy)

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Micrometric phyllosilicate films along fault slip surfaces (SSs) can drastically reduce friction, yet they are unexpected in clay‐poor carbonate platforms. We inquire how a major carbonate‐hosted, seismogenic strike‐slip fault can develop weak slip interfaces and undergo dynamic weakening despite an intrinsically strong host rock.

Oil film measurement in polytetrafluoroethylene-faced thrust pad bearings for hydrogenerator applications [PDF]

, 2006
There is a growing trend in the replacement of the babbit facing in thrust pad bearings with a composite polytetrafluoroethylene (PTFE) surface layer. The PTFE-faced bearings have been shown to allow a greater specific pressure, reduce thermal crowning ...

Computational fluid dynamics analysis to improve hydrostatic thrust bearings: number of pockets and shape configuration analysis

Journal of Engineering and Applied Science
Hydrostatic bearings are expected to attract significant attention in the coming years due to their wide use in engineering applications, such as high-speed machine tool spindles, fast-moving machinery, and precision grinding tools.

High Temperature Friction and Strength of Felsite and Basalt: Implications for Supercritical EGS at Krafla, Iceland

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract One promising potential site for extracting supercritical geothermal fluids is the Krafla volcano, Iceland, into which a borehole was drilled very close to a shallow rhyolite magma chamber at about 2 km depth. Besides the technical challenge to drill in this setting, the extreme temperature conditions of T > 900°C close to the magma body may ...

Mechanobiology in Stem Cell‐Based Bioprinting

Cell Proliferation, Volume 59, Issue 5, May 2026.
Mechanobiology in stem cell‐based bioprinting is an emerging field that bridges the mechanical conditions of the bioprinting process with the regulation of stem cell behaviour for engineering living tissues. Stresses encountered during bioprinting, together with the mechanical properties of bioinks, play a critical role in regulating stem cell ...

Beyond the chaos: How architecture structures tumour biology

The FEBS Journal, Volume 293, Issue 9, Page 2519-2540, May 2026.
Tissue architecture shapes tumour initiation and progression through multiple interconnected layers continuously remodelled over time. This review outlines how physical forces, biochemical cues, cellular niches and systemic influences contribute to tumour evolution.
