Uncovering the Key Factors Influencing Phytochemical and Phytopharmacological Properties During Medicinal Plant Processing

eFood, Volume 7, Issue 1, February 2026.
From farm to pharma, this review details the engineering of quality in medicinal plants through a science‐driven approach: it first elucidates how genetic and environmental factors inscribe the plant's phytochemical and phytopharmacological profile before harvest, and then dissects the postharvest techniques and technologies—chemical and thermal pre ...

Diffusion Tensor MRI and Spherical‐Deconvolution‐Based Tractography on an Ultra‐Low Field Portable MRI System

Human Brain Mapping, Volume 47, Issue 2, February 1, 2026.
A Portable ULF scanner (1a) imaged a subject (1b) and phantom (1c) to give T2 (2a) and DW (2b) acquisitions alongside a regularised phantom fieldmap (2c). These were processed to give corrected DTI (3a) and CSD (3b) derivatives and were used for whole‐brain tractography (3c) in a feasible acquisition duration.

Impact of Growth Temperature and Al/N Ratio on AlN Films Grown by Radio‐Frequency Molecular Beam Epitaxy on GaN Templates

physica status solidi (b), Volume 263, Issue 2, February 2026.
The growth mechanism of AlN films for high electron mobility transistors passivation is systematically investigated via radio‐frequency molecular beam epitaxy. While high‐temperature growth (700 °C) utilizes excess aluminum as a surfactant forming surface droplets, low‐temperature growth (300 °C) traps excess aluminum as defective metallic interlayers.

Development of sprayed ceramic seal systems for turbine gas path sealing [PDF]

A ceramic seal system is reported that employs plasma-sprayed graded metal/ceramic yttria stabilized zirconium oxide (YSZ). The performance characteristics of several YSZ configurations were determined through rig testing for thermal shock resistance ...

Novel Wide‐Spectrum Virucidal Lipid Nanoparticles

Small, Volume 22, Issue 7, 2 February 2026.
POSTAN is a novel broad‐spectrum antiviral nanoparticle that combines safety with potent virucidal activity. Composed of biocompatible lipids, it mimics heparan sulfate proteoglycans and lipid rafts exploited by viruses, thereby dismantling viral envelopes and blocking replication.

Monitoring Interfacial Dynamics of a Zinc‐Ion Battery Cathode Using In Situ Grazing Incidence X‐Ray Absorption Spectroscopy: A Case Study of Manganese Dioxide

Small Methods, Volume 10, Issue 3, 9 February 2026.
This study demonstrates the first in situ application of grazing incidence X‐ray absorption spectroscopy (GI‐XAS) to probe interfacial degradation in MnO2 cathodes of zinc‐ion batteries. By varying the incidence angle, surface‐ and bulk‐specific redox changes are revealed, highlighting Mn dissolution and incomplete reoxidation as key factors driving ...

Numerical Modeling of Purely Active (Plume‐Produced) Continental Rifting and Break‐Up

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract In contrast to the traditional mechanism of passive continental rifting (driven by far‐field tectonic forces), the active rifting‐to‐break‐up processes (caused by rising mantle plumes) are still poorly understood. However, most episodes of fragmentation of the last supercontinent Pangea were relatively shortly preceded (within ∼10 Myr) by the ...
