Support‐Driven Hydrogen Migration Enhances Ammonia Decomposition in Direct Ammonia Protonic Ceramic Fuel Cells

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
Enhanced hydrogen species migration enabled by FN/BZY catalyst mitigates intermediate accumulation and improves DA‐PCFC performance during ammonia decomposition. Ammonia, with its high hydrogen density and carbon‐free nature, serves as ideal fuel for direct ammonia protonic ceramic fuel cells (DA‐PCFCs).

A Tale of Two Heterocycles: How Oxygen and Sulfur Shape Divergent Kemp Reactivity

Journal of Physical Organic Chemistry, Volume 39, Issue 11, November 2026.
Like benzisoxazoles, benzisothiazoles also undergo Kemp elimination, with rates accelerated by aprotic polar solvents and electron‐withdrawing groups. Oxygen‐containing heterocycles exhibit more localized negative charges than sulfur analogs, resulting in a more pronounced catalytic response to these environmental factors. ABSTRACT The Kemp elimination

Lachnospiraceae in the Food–Gut Axis: A Critical Review of Dietary Modulation, Immune Regulation, and Translational Barriers

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 6, November 2026.
ABSTRACT The interplay between diet, gut microbiota, and host immunity is central to food science. The Lachnospiraceae family ferments dietary fibers to produce short‐chain fatty acids (SCFAs), notably butyrate and propionate, with immunomodulatory potential. This critical review distinguishes established findings from hypotheses.

Rice Productivity in Saline–Alkaline Soils: Constraints, Microbiome‐Mediated Regulation and Management Strategies

Journal of Agronomy and Crop Science, Volume 212, Issue 6, November 2026.
ABSTRACT Saline–alkaline soils are widespread and represent a particularly restrictive environment for rice, especially in arid and semi‐arid regions. These soils commonly combine elevated salinity with high pH, sodium‐related soil constraints and bicarbonate/carbonate accumulation, resulting in severe physicochemical and nutritional limitations.
