4D imaging of a porous carbonate rock under triaxial loading: quantitative correlation between local porosity and strain

Journal of Synchrotron Radiation, Volume 33, Issue 5, Page 1509-1521, September 2026.
A 4D X‐ray computed tomography experimental campaign was carried out on a porous carbonate rock to investigate the link between initial porosity and deformation modes. This paper presents the experiment and the methods used to explore this relationship.The study of the mechanical behaviour of carbonate rocks has benefited from the evolution of ...

Impact of Human Melanopsin Gene (OPN4) Polymorphisms (I394T, P10L) on Nocturnal Melatonin and Daily Rhythms in Young Adults

Journal of Pineal Research, Volume 78, Issue 5, September 2026.
ABSTRACT The present study investigates the impact of two missense SNPs in the human melanopsin gene OPN4 ‐I394T (rs1079610) and P10L (rs2675703)‐ on non‐image‐forming (NIF) physiological and behavioural outputs in healthy young adults under real‐world conditions.

Time‐dependent (Creep) Compaction in Volcanic Rocks

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Porous volcanic rocks form volcanic edifices and host key geothermal reservoirs worldwide. When subjected to constant stress above dilatancy in the brittle regime, these materials undergo time‐dependent failure known as brittle creep. In the ductile regime, where deformation is compactive, time‐dependent compaction—compaction creep—has been ...

Extrusion‐Based Additive Manufacturing of Advanced Ceramics: Strengthening Mechanisms and Process Optimization Review

Advanced Engineering Materials, Volume 28, Issue 16, 19 August 2026.
This review comprehensively evaluates extrusion‐based additive manufacturing for advanced ceramics, detailing feedstock options and key process parameters. By critically addressing defect mechanisms like porosity and cracking, the work highlights optimization strategies through machine learning and advanced postprocessing.
