Nanomaterials‐Decorated Biomass‐Derived Carbon for Overall Water Splitting: Interfacial Engineering, Mechanistic Insights, and Device Translation

The Chemical Record, Volume 26, Issue 8, August 2026.
Biomass‐derived carbon provides a sustainable, porous, and conductive scaffold that stabilizes nanomaterials for bifunctional hydrogen evolution reaction/oxygen evolution reaction catalysis. This review summarizes design strategies (defects, heteroatom doping, heterostructures, single atoms), mechanistic/density functional theory insights, degradation ...

Hydrothermal Manganese‐Oxide Mineralization of a Carbonate Ooze, Samoan Hotspot Region, South Pacific Ocean

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract Low‐temperature hydrothermal manganese oxides occur throughout the global oceans. However, the hydrothermal replacement of a carbonate ooze by manganese oxides is described here for the first time. The 24 samples dredged from three locations around the Territory of American Samoa in the South Pacific Ocean include six samples with remnant ...

Iron Physiology and Its Impact on Atopic Diseases: An EAACI Taskforce Report

Allergy, Volume 81, Issue 8, Page 2675-2712, August 2026.
ABSTRACT Iron is essential for oxygen transport, energy metabolism, and immune regulation. Yet iron deficiency is the most common micronutrient disorder across all age groups, affecting nearly one quarter of the global population. Iron deficiency triggers nutritional immunity, a host defense mechanism that withholds and redistributes iron, contributing

Mercury removal from drinking water by single iron and binary iron-manganese oxyhydroxides

Desalination and Water Treatment, 2015
In this study, single iron oxyhydroxides (FeOOH) and binary iron/manganese (FeMnOOH) oxyhydroxides were used to serve as potential mercury adsorbents. The selection of the optimum adsorbent and the corresponding conditions of the synthesis was based not only on its maximum Hg(II) adsorption capacity but also on its ability to achieve the mercury health

Tracing the Persistence and Role of Deep‐Sea Iron Sources in the Pacific Ocean Over the Last 23 Million Years

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Iron (Fe) plays a critical role in marine productivity and the global carbon cycle. The relative contribution of different Fe sources such as atmospheric aerosols, sediment dissolution, and submarine hydrothermalism influences the distribution and biogeochemical cycling of Fe in the ocean. However, distinguishing these Fe sources over time has

Nanofibrous aluminum oxyhydroxide modified with manganese ions (II) - precursors of manganese{containing catalysts of methane deep oxidation

Известия Томского политехнического университета: Инжиниринг георесурсов, 2019
The one-step preparation of precursors for MnOx/Al2O3 catalytic systems for high*temperature incineration is a promising technology for the catalysts. The aim of the research is to establish the effect of manganese ions (II) concentration on catalytic properties of nanofibrous aluminum oxyhydroxide, modified with manganese ion (II) at methane complete ...
