From Reactive Remediation to Predictive Prevention: A Systems Synthesis of Global Soil Salinization and Sodicity

Global Change Biology, Volume 32, Issue 10, October 2026.
Salty soils are spreading across the world's farmland, often building up unnoticed for years before crop yields fall sharply and repair becomes slow and costly. Our review shows that this damage comes from linked problems in soil chemistry, water management, and policy, so fixing any one of them alone rarely works.

1,4-Butanediol as a Reducing Agent in Transfer Hydrogenation Reactions

, 2010
1,4-Butanediol is able to deliver two equivalents of H(2) in hydrogen-transfer reactions to ketones, imines, and alkenes. Unlike simple alcohols, which establish equilibrium in the reduction of ketones, 1,4-butanediol acts essentially irreversibly owing ...

Microbial volatile compounds enhance drought resilience and productivity in CAM and C3 crops

Plant Biology, Volume 28, Issue 6, Page 1820-1833, October 2026.
Microbial volatiles EV and CAMP, derived from Bacillus spp. and Beauveria pseudobassiana associated with agaves and cacti, respectively, enhance drought resilience and productivity in Agave tequilana and tomato. Abstract Plants interact with their associated microbiota through diverse chemical cues, including microbial volatile organic compounds (mVOCs)

2,3-butanediol in experimental myocardial ischaemia in pigs.

, 1991
To investigate the role of 2,3-butanediol in myocardial ischaemia we analysed this compound in pig's myocardium and blood. Ischaemia was induced by ligation of a coronary artery.

Piperazine and Morpholine Protoporphyrin IX Derivatives Intensify Biomolecules Oxidation and Phototoxicity in Triple‐Negative Breast Cancer

ChemMedChem, Volume 21, Issue 17, 14 September 2026.
Protoporphyrin IX derivatives bearing piperazine or morpholine substituents exhibit enhanced cellular retention and photodynamic activity in triple‐negative breast cancer cells. Structural modification promotes oxidative stress, alters mitochondrial membrane potential, and increases caspase‐3 activity, providing new structure–activity relationship ...

Inactivation of hydrogenase-3 leads to enhancement of 1,3-propanediol and 2,3-butanediol production by Klebsiella pneumoniae [PDF]

Klebsiella pneumoniae can use glucose or glycerol as carbon sources to produce 1,3-propanediol or 2,3-butanediol, respectively. In the metabolism of Klebsiella pneumoniae, hydrogenase-3 is responsible for H2 production from formic acid, but it is not ...

Hydroformylation of Olefins With Paraformaldehyde Catalyzed by a Rhodium(I)/Diphosphine/Diphosphoramidite System

European Journal of Organic Chemistry, Volume 29, Issue 34, 11 September 2026.
A new dual‐ligand rhodium catalytic system based on [RhCl(cod)]2, BINAP or BIPHEP, and a diphosphoramidite ligand enables the hydroformylation of olefins using paraformaldehyde as a syngas surrogate. The system efficiently converts vinyl arenes, alkyl olefins, cyclopentene, and allyl acetate with high activity and regioselectivity.
