Recent Advances in Catalytic Conversion of Bioethanol to 1,3‐Butadiene: Reaction Mechanism, Catalyst Design, and Process Scalability

ChemSusChem, Volume 19, Issue 1, January 2026.
Catalytic conversion of ethanol to 1,3‐butadiene (BD) can proceed via one‐step and two‐step routes. In the one‐step process, pure and metal‐modified MgO–SiO2 catalysts enable direct ethanol transformation to BD, while ZrO2‐based catalysts drive the two‐step pathway.

Unravelling the Microstructural Parameters to Optical Property Relations in Carbon Quantum Dots Coalesced From Two Organic Waste Precursors

Nano Select, Volume 7, Issue 1, January 2026.
Carbon quantum dots synthesized from two different biomass precursors via same route of hydrothermal bottom's up approach displays microstructural variations and corresponding optical property and function dependence. Variation in crystallite size, micro‐strain, crystallinity and Urbach band edge subsequently regulates the photoluminescence emission ...

Physiology of nitrogen: A life or death matter

Experimental Physiology, Volume 111, Issue 1, Page 270-282, 1 January 2026.
Abstract With each breath, four out of every five molecules we inspire are nitrogen (N2), since this gas constitutes ∼80% of the atmospheric air that surrounds us. Despite its abundance and unlike molecular oxygen, N2 has traditionally held less appeal among physiologists given its lack of reactivity and corresponding inability to support combustion or

Chronic and Acute Toxicity Effects of Cypermethrin on Growth, Enzyme Activity, and Biochemical Nutrients in Carp Fish (Cirrhinus mrigala)

Aquaculture Research, Volume 2026, Issue 1, 2026.
Pesticide pollution in aquatic ecosystems poses a prevalent and pressing concern, with a particular emphasis on developing nations. The effect of cypermethrin (CP), a synthetic type II pyrethroid pesticide, on phenotypic traits, enzyme activities, and biochemical nutrients in freshwater, mrigal fish (Cirrhinus mrigala) was investigated in this study ...

Quantitative Treatments for Explaining the Mechanism and Kinetics of Catalytic Electron Transfers in Murburn Processes, Particularly Involving Heme Enzymes Like (Per)oxidases and P450s

BioMed Research International, Volume 2026, Issue 1, 2026.
The seminal Michaelis–Menten theorization for biological catalysis was based on “transition state” (TS), involving the formation of a topologically complementary substrate (S) and enzyme (E) complex (ES) at the “active site” of the latter. Rudolph Marcus put forth the theory of outer sphere electron transfer (ET) in a “donor–acceptor” TS complex, which

Transfer Hydrogenation: Advances in Manganese and Nickel Metal Catalysis

Journal of Chemistry, Volume 2026, Issue 1, 2026.
Transfer hydrogenation (TH) of ketones, catalyzed by transition–metal complexes, produces alcohols, which are important building blocks in the pharmaceutical and fine chemical industries. For a long time, catalysts based on noble metals such as ruthenium, rhodium, and iridium have dominated the TH of ketones.
