Mesoporous Hollow Carbon Spheres/Nanofibers Anchored With Conductive Bimetallic for Efficient Microwave Absorption

open access: yesRare Metals, EarlyView.
ABSTRACT To break electromagnetic wave absorption (EMA) tech's single‐attenuation bottleneck, enhancing multi‐wave absorption synergy in composites is key for microstructure design. This study uses mesoporous hollow carbon spheres to make metal nanospheres with cobalt, iron, and nickel nanoparticles, then encapsulates them via electrospinning into a ...

Benzochromanone and Benzochromene Natural Products: Synthetic Strategies and Total Syntheses

open access: yesThe Chemical Record, EarlyView.
This work outlines synthetic strategies for natural products with benzochromanone and benzochromene cores. Key achievements include total syntheses of xanthones, blennolide C, gonytolide C, and teretifolione B. Spirochromanone intermediates, benzyne–furan Diels–Alder reactions, and enzymatic resolution enabled efficient and enantioselective access to ...

Response of Fecal Bacteria and Fungi to Tannin‐Rich Diets in Sika Deer (Cervus nippon): Evidence from Both Feeding Experiments and Field Investigations

open access: yesIntegrative Zoology, EarlyView.
Feeding with tannin‐rich diets altered the fecal microbial composition and increased the relative abundance of tannin‐degrading microbes. We hypothesize that fecal bacteria and fungi may play important roles in helping herbivores adapt to tannin‐rich diets but respond to different tannin concentrations varies.

Contact Allergy to Ingredients of Hair Cosmetics Associated with Occupational and Non‐Occupational Exposure—Trends from 1995 to 2020 in Central Europe, with or without Regulation

open access: yesContact Dermatitis, EarlyView.
Among 2678 female hairdressers and 6244 female consumers with contact dermatitis suspected to be related to use of hair cosmetics, including dyes, patch tested in the IVDK between 1995 and 2020, diverging contact allergy trends were observed. In the case of toluene‐2,5‐diamine (PTD) shown in the figure, sensitization was at a stable, high level in ...

Importance of interaction between the matrix effect and microbial metabolism in the bioavailability of lignans

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 4, Page 2180-2189, 15 March 2026.
Abstract BACKGROUND Plant‐lignans are polyphenols with low bioavailability and bioactivity that are transformed by the intestinal microbiota into enterolignans. Our hypotheses are: (i) the way in which plant‐lignans are ingested in the diet affects, in a decisive way, the microbial metabolism of these compounds and (ii) an increase in lignan ...

A Para‐Selective Kolbe–Schmitt Reaction

open access: yesAngewandte Chemie, Volume 138, Issue 4, 22 January 2026.
Discovered over 150 years ago, the Kolbe–Schmitt carboxylation has established itself as one of the most well‐known chemical reactions. However, the process often requires extreme pressures and high temperatures. Here, we present a unique para‐selective Kolbe–Schmitt‐type carboxylation that proceeds at relatively low temperatures and uses near ...
