Liquid Crystal Elastomers Filaments for Adaptive Textiles and Soft Robotics: A Processing‐Centric Review

open access: yesMacromolecular Rapid Communications, Volume 47, Issue 15, 4 August 2026.
Liquid crystal elastomer (LCE) filaments are fabricated through extrusion with in‐process UV curing, enabling controlled flow alignment and network locking of mesogens. The resulting structure responds to thermal or optical stimuli, inducing molecular reorientation and macroscopic contraction.

Traceability in Chemical Analysis – What Does that Mean?

open access: yesCHIMIA, 1999
Today, many results of chemical analyses show a poor comparability as can be shown by interlaboratory comparisons. This is partly due to the fact that a widely accepted metrological measurement basis is not yet existing for chemical analysis ...

A PLP‐SEC Investigation of Di(Ethylene Glycol) Methyl Ether Methacrylate Radical Polymerization Propagation Kinetics in Solution

open access: yesMacromolecular Reaction Engineering, Volume 20, Issue 4, August 2026.
The propagation rate coefficient of di(ethylene glycol) methyl ether methacrylate exhibits the same temperature dependency but is a factor of 12 higher in aqueous solution compared to bulk. Smaller increases are observed in ethanol and ethanol/water mixtures, with the value of the rate coefficient decreasing as the monomer concentration in solution is ...

Community Participation as a Pathway to Strengthen National Precipitation Isotope Products in New Zealand

open access: yesJournal of the Royal Society of New Zealand, Volume 56, Issue 4, August 2026.
Accurate environmental and climate modelling depends on the availability of large observational datasets, yet the generation of such data is often costly and logistically challenging for individual research groups. This limitation is particularly acute in New Zealand, where geographic isolation, complex topography, and strong climatic gradients require

First European Interlaboratory Ring Test Study to Detect DNA of Crayfish and the Crayfish Plague Pathogen From Water Samples

open access: yesEnvironmental DNA
In recent years, European countries have intensified efforts to control or limit the spread of invasive freshwater crayfish and the crayfish plague pathogen Aphanomyces astaci, while working to conserve native species such as the noble crayfish (Astacus ...

Supervised Machine Learning Approach to Iron Meteorite Classification Using Random Forest: A Predictive Model to Classify Ungrouped Irons

open access: yesEarth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Iron meteorites provide insight into the formation processes of planetary cores from the early Solar System. Through further classifying individual irons into specific groups, which are assumed to represent a common parent body, greater information can be yielded into the formation processes of those bodies.

Developing New Amphibole Thermobarometers to Constrain High P‐T Hydration Processes of Basic‐Ultrabasic Rocks

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract Amphibole compositions record high‐pressure‐temperature (P‐T) hydration processes during magmatism and metamorphism in the deep Earth. However, amphibole thermobarometers calibrated for basic–ultrabasic systems are scarce. To address this issue, we compiled Ca‐amphibole data from published equilibrium experiments and used machine‐learning ...

Three Decades of Soil N2O Research—Insights and Gaps

open access: yesGlobal Change Biology, Volume 32, Issue 8, August 2026.
Progress in N2O Research and Key Breakthroughs and Transitions from 1990 to 2025 across three domains: (A) process understanding, (B) microbial ecology, and (C) modelling of soil N2O emissions. ABSTRACT Nitrous oxide (N2O) is a potent greenhouse gas (GHG) whose atmospheric concentration continues to rise, largely driven by nitrogen (N) inputs to ...

Enduring autism‐like phenotypes and deregulated hypothalamic prosocial peptides after early‐life exposure to indoor flame retardants in male C57BL/6 mice

open access: yesJournal of Neuroendocrinology, Volume 38, Issue 8, August 2026.
Abstract Polybrominated diphenyl ethers (PBDEs) are neuroendocrine‐disrupting chemicals that produce adverse neurodevelopmental effects. PBDEs have been implicated as risk factors for autism spectrum disorder (ASD), which is characterized by abnormal psychosocial functioning and is commonly comorbid with cognitive deficits and sensory abnormalities ...
