The impacts of biological invasions

open access: yesBiological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Preliminary Numerical Evaluation of Directly Heated Structured Packings to be Used for Separation Processes

open access: yesChemie Ingenieur Technik, EarlyView.
In terms of electrification, directly heated structured packings are a viable option. They offer the advantage of providing energy where it is required, thereby positively impacting the separation process and helping to minimize heat loss. Using CO2 desorption from aqueous MEA solution as an exemplary process, different heating strategies are compared.

Numerical and experimental study on P‐wave propagation across a rock joint with different orientations

open access: yesDeep Underground Science and Engineering, EarlyView.
Joint orientation significantly affects P‐wave velocity, with the highest velocity at zero‐degree angles, decreasing to 30° as the angle increases. The velocity increases slightly from 30 to 45 degrees but sharply decreases from 45 to 90 degrees. Abstract Determination of the required parameters in different science contexts using the ultrasonic wave ...

Multi‐Dimensional Conductive Nanocomposites for Flexible Electronics

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Multi‐dimensional conductive nanocomposites integrate 0D, 1D, and 2D nanomaterials through spatial structure regulation and interface engineering, achieving “1 + 1 > 2” synergistic effects. By leveraging 0D filling to reduce contact resistance, 1D bridging to construct continuous conductive paths, and 2D supporting to enhance mechanical stability ...

Two Shades of Green? Gender Differences in Environmental Concern and Activism

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT This study examines gender differences in environmental concern and activism using data from the World Values Survey. The results indicate that women are more likely than men to be concerned about the environment, but are less likely to engage in environmental activism.

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.
