Effects of Polyvalent Cations on FTIR Spectra of Organic Matter–Cation Associations

Journal of Plant Nutrition and Soil Science, Volume 189, Issue 2, Page 230-242, April 2026.
ABSTRACT Background The composition of soil organic matter (SOM) can be characterized by functional groups in the organic matter (OM). The carboxylic acid and carboxylate groups of OM show specific absorption bands in Fourier‐transform infrared (FTIR) spectra. However, cation–OM interactions may affect absorption bands and limit spectral interpretation

Chromosome 1 Open Reading Frame 35 Drives Colorectal Cancer Progression by Enhancing Tumor‐Intrinsic Proliferation and CD8+ T Cell Suppression

MedComm, Volume 7, Issue 4, April 2026.
This study identifies C1orf35 as a key driver of colorectal cancer progression through a dual mechanism. It promotes tumor‐intrinsic cell proliferation and migration via the c‐Myc/PYCR2 axis, and suppresses anti‐tumor immunity by impairing CD8+ T‐cell immune surveillance, nominating it as a novel therapeutic target in colorectal cancer.

Structure–Property–Performance Relationship of Graphene Oxide Modified Composite Membranes for Anion Exchange Membrane Electrolyzers

SPE Polymers, Volume 7, Issue 2, April 2026.
The integration of graphene oxide into anion exchange membranes enhances ion conductivity, leading to improved hydrogen production efficiency. ABSTRACT In this study, graphene oxide (GO)‐modified poly (phenylene oxide, PPO) anion exchange membranes (F/GO) were developed for application in anion exchange membrane electrolyzers (AEMELs).

Identifying the Extent of River‐Influenced Waters of the Transpolar Drift With In Situ Measurements of Dissolved Organic Matter Fluorescence and Seawater Density

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract The oceanic component of the Transpolar Drift (TPD) is a key component of Arctic Ocean surface circulation. However, our understanding of its spatial extent and influence on the underlying water column remains limited. This study leverages a unique high spatial resolution oceanographic transect from August 2022 (late summer), first to identify
