Nanoparticle‐Reinforced Ti‐6Al‐4V Metal Matrix Nanocomposites for Additive Manufacturing: Synthesis Methods, Process Optimization, and Performance Enhancements

open access: yesEngineering Reports, Volume 8, Issue 9, September 2026.
Reinforcing Ti‐6Al‐4V with nanoparticles to form metal matrix nanocomposites (MMNCs) offers a promising solution. This review explores current additive manufacturing approaches for producing Ti‐6Al‐4V metal matrix nanocomposites. Key fabrication parameters, synthesis strategies, and future directions for high‐quality MMNCs in metal additive ...

Radiation Dose Optimisation Through Artificial Intelligence (AI)‐based Auto‐Thorax Collimation

open access: yesJournal of Medical Radiation Sciences, Volume 73, Issue 3, Page 300-308, September 2026.
This study evaluated AI‐based Auto‐Thorax Collimation (ATC) for radiation dose optimisation in posteroanterior chest radiography compared with manual collimation. ATC demonstrated tighter lateral collimation and reduced inter‐operator variability while maintaining comparable repeat rates.

Human In Vivo Disc Mechanics in Flexion, Extension, and Diurnal Loading With Aging and Degeneration

open access: yesJOR SPINE, Volume 9, Issue 3, September 2026.
ABSTRACT Background The intervertebral disc serves a critical role in spine function, but with aging and degeneration the disc undergoes changes that alter disc mechanics, and degeneration is often implicated in low back pain. The objective of this study was to quantify and evaluate the impact of aging and degeneration on in vivo lumbar disc mechanics ...

A Review on Polymer Bonding Through Interdiffusion and Role of Deformation‐Acceleration

open access: yesMacromolecular Materials and Engineering, Volume 311, Issue 9, September 2026.
Polymer bonding is reframed through deformation‐induced bonding, an energy‐efficient route that joins polymer films without conventional heat‐intensive or adhesive‐based processing. By comparing established bonding methods with deformation‐induced bonding, this review highlights potential energy and cost savings while identifying opportunities across ...

Mazus dabieshanensis sp. nov. (Mazaceae) from eastern China

open access: yesNordic Journal of Botany, Volume 2026, Issue 9, September 2026.
Mazus dabieshanensis, a newly described species endemic to the Dabieshan Mountains in eastern China, is illustrated and described. Molecular phylogenetic analyses based on nuclear and chloroplast DNA sequences consistently demonstrate that this new species forms a stable clade with other Mazus species characterized by a pubescent ovary. Morphologically,

Range‐wide sampling reveals cryptic lineages but largely conserved mycorrhizal associations in the Japanese fairy lantern Thismia kobensis

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1407-1418, September 2026.
The jewel‐like flowers of Thismia are as rare as they are beautiful, often recorded from only a single site per species. Access to 15 populations of T. kobensis has enabled an uncommon, range‐wide assessment of morphology, genetics, and fungal partners. Our analyses showed that T.

Stress‐Adaptive Biomaterials With Tunable Yielding Architectures Regulate Organoid Morphogenesis

open access: yesSmall, Volume 22, Issue 50, 7 September 2026.
Granular hydrogels are developed to tune the yield stress levels at which 3D tissue culture matrices undergo plastic deformation. We use these materials to regulate growth‐induced stresses, with demonstrable effects on cancer spheroid invasion and brain organoid morphogenesis.
