Understanding Degradation Mechanisms in Water‐In‐Salt Electrolyte. Part 2: Impact of the Electrochemical Parameters on the Cycling Behavior of LiFePO4 versus TiS2

open access: yesBatteries &Supercaps, EarlyView.
Cycling water‐in‐salt batteries involves complex degradation processes that require multiprobe analysis. Using online electrochemical mass spectrometry (OEMS), postmortem X‐ray photoemission spectroscopy (XPS) (including hard‐XPS), and scanning electron microscopy (SEM), the degradation mechanisms are examined in composite electrodes (TiS2 and LiFePO4)

Form flows function: Learner‐centered game Re‐design in a STEM classroom

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Re‐designing games facilitates interest‐driven learning and immerses learners in systems thinking. However, there are limited studies exploring how the form and function of tabletop games influence learners' design decisions and learning experiences. To address this gap, we conducted a mixed‐methods study in a STEM classroom in western Canada.

Subterranean environments contribute to three‐quarters of classified ecosystem services

open access: yesBiological Reviews, EarlyView.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Scale Interactions and Galaxy Evolution [PDF]

open access: yesAstrophysics and Space Science, 2003
To understand galaxies and their evolution, it is necessary to describe how the different scales interact: how the microscopic physics, such as star formation, or the large scale physics, such as galaxy interactions may modify the galaxy global shapes.

Chlorinated Paracyclophanes: Composition Analysis and Direct Metal‐Free Alkylation with n‐BuLi

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A transition‐metal‐free alkylation of pseudo‐para dichloro[2.2]paracyclophane (Cl2‐PCP) is reported, utilizing the purified pseudo‐para isomer and n‐butyllithium (BuLi). Optimization with the chelating agent TMEDA and refluxing n‐heptane significantly boosted selectivity and reaction rate, providing the dialkylated product in 22% isolated yield.

Akkermansia muciniphila enhances chicken resistance to infectious bronchitis virus by boosting GABA synthesis and suppressing the NF‐κB inflammatory pathway

open access: yesiMetaOmics, EarlyView.
Infectious bronchitis virus (IBV) represents a major threat to poultry production, with current control strategies offering limited protection. In this study, we demonstrate gut microbiome is a critical determinant of IBV resistance using fecal microbiota transplantation.

Chemo-dynamical Evolution of Galaxies

open access: yes, 2023
Stars are fossils that retain the history of their host galaxies. Elements heavier than helium are created inside stars and are ejected when they die. From the spatial distribution of elements in galaxies, it is therefore possible to constrain the physical processes during galaxy formation and evolution.

Arbuscular mycorrhizal fungal community abundance, functions, and symbiotic interactions revealed by root metatranscriptomes

open access: yesiMetaOmics, EarlyView.
Paradigm shift: PCR‐free methods reveal 6–15‐fold higher arbuscular mycorrhizal (AM) fungal abundance than metabarcoding, exposing systematic underestimation across decades of research. Predictive power: AM fungal abundance serves as a community‐level trait that predicts crop yield under drought conditions.

Ginseng polysaccharides prevent mastitis through Lactobacillus murinus‐derived deoxycholic acid and TGR5 signaling

open access: yesiMetaOmics, EarlyView.
Prebiotic Ginseng polysaccharides (GP) alleviate mastitis through selective enrichment of gut L. murinus, which elevates its anti‐inflammatory metabolite deoxycholic acid (DCA). Circulating DCA engages mammary epithelial TGR5 receptors, triggering the cAMP–PKA pathway to suppress NF‐κB/NLRP3‐mediated inflammation.
