Organ Size and Metabolic Rate Co‐Vary with Dimensions of the Obstetric Pelvis: The Metabolic Coordination of Childbirth Hypothesis

American Journal of Biological Anthropology, Volume 191, Issue 1, September 2026.
Among South Asian women, those with larger organ mass and energy expenditure, indicating greater capacity to promote fetal growth, had larger pelvic dimensions, partly explained by linear growth patterns. However, body fat correlated with energy expenditure but not pelvic dimensions, helping explain why high adiposity increases risk of obstructed ...

Overview of Photochemical Reactions for the Synthesis of Aza and Oxa‐Spirocyclic Compounds Under Visible Light Irradiation

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
This review presents the visible‐light‐mediated photochemical reaction for the synthesis of aza, oxa, and aza–oxa spirocyclic compounds via photoinduced electron transfer (PET), hydrogen atom transfer (HAT), single‐electron transfer (SET), or energy transfer (EnT) pathways.

Effects of Wheat Bran‐Derived Arabinoxylan Oligosaccharides on Dough and Noodle‐Making Properties

Cereal Chemistry, Volume 103, Issue 5, Page 707-716, September/October 2026.
ABSTRACT Background and Objectives This study investigates the structural modifications of arabinoxylan (AX) through enzymatic hydrolysis and evaluates the potential application of arabinoxylan oligosaccharides (AXOS) as functional ingredients in wheat noodles, contrasting their effects with those of native AX.

Enhancing Selectivity of AuCu Electrocatalysts for CO2 Electroreduction in Chloride Electrolyte

ChemCatChem, Volume 18, Issue 17, 14 September 2026.
Synergistic effects of Au–Cu bimetallic electrocatalysts in chloride electrolytes were studied by combining experiments and computational modeling. Electrocatalysts were electrodeposited on GDEs and tested in KHCO3 and KCl electrolytes. AuCu and Au2Cu improved CO production in KCl, reaching up to 80% faradaic efficiency.

In‐situ asphaltene capture with iron oxide nanoparticles in steam‐assisted gravity drainage (SAGD) for improved recovery and partial upgrading of bitumen

The Canadian Journal of Chemical Engineering, Volume 104, Issue 9, Page 4787-4808, September 2026.
Key improvements obtained by incorporating nanoparticles into a lab‐scale SAGD process configuration. The bar plots show enhanced oil recovery, reduced viscosity, and increased asphaltene adsorption in nanoparticle‐assisted scenarios compared with conventional SAGD.
