Where is mineral ballast important for surface export of particulate organic carbon in the ocean? [PDF]

, 2014
Correlations between particulate organic carbon (POC) and mineral fluxes in the deep ocean have inspired the inclusion of ‘ballast effect’ parameterizations in carbon cycle models. A recent study demonstrated regional variability in the effect of ballast

Spectrally Coordinated Plasmonic–Photothermal Photocatalysts for Mineralization of Mixed Indoor VOCs Under White LED Illumination

Advanced Materials, EarlyView.
A plasmonic–photothermal–photocatalytic hybrid comprising Cu(II)‐grafted TiO2, yolk–shell Au@SiO2, and reduced graphene oxide sheets (CuT/AuSi‐GS) harvests full‐spectrum white light‐emitting diode (LED) light via complementary photocatalytic oxidation, localized surface‐plasmon‐resonance‐induced electric‐field enhancement, and photothermal acceleration.

Sources of nitrogen for winter wheat in organic cropping systems [PDF]

, 2013
In organic cropping systems, legumes, cover crops, residue incorporation, and manure application are used to maintain soil fertility, but the contributions of these management practices to soil nitrogen (N) supply remain obscure.

Multi‐Biomimetic Structural Colors Inspired by Pearls and Bird Feathers

Advanced Materials, EarlyView.
A dual‐biomimetic strategy mimicking pearls and bird feathers is proposed to construct full‐gamut structural colors. By integrating a non‐strictly periodic inorganic multilayer architecture with tunable light absorbers, this facile approach circumvents the complex fabrication of traditional 1D photonic crystals, offering immense potential for cosmetics,

A Thermoreversible Gelation Pathway to Plant Cuticle‐Inspired Biopolymer Aerogel Monoliths Based on Network‐Spherulitic Crystal Assemblies

Advanced Materials, EarlyView.
To address functionality limitations in plant‐based and industrially compostable polymer aerogels, this work introduces bio‐inspired aerogels with broadened functionality. Inspired by functional plant tissues, lightweight biopolymer aerogels based on exclusively stereocomplex crystals are fabricated, featuring hierarchically macro‐/meso‐porous ...

Forest soil organic carbon responses to nitrogen addition are pH dependent

Geoderma
Organo–mineral associations are central to the persistence of soil organic carbon (SOC) in forest mineral soils, yet how nitrogen (N) enrichment affects mineral-associated stabilization across contrasting soil chemistries remains unclear.

Defect‐Driven Charge Separation in Ba‐Doped SrTiO3: Correlating Photoelectrochemical Performance With Dye‐Selective Photocatalysis

Advanced Materials Interfaces, EarlyView.
Ba‐doped SrTiO3 perovskites establish a direct correlation between photoelectrochemical activity and photocatalytic performance. Optimized Ba0.5Sr0.5TiO3 exhibits enhanced charge separation, photocurrent generation, and visible‐light‐driven dye degradation through defect‐induced oxygen vacancies and lattice distortion.

Dissolved Inorganic Carbon Destabilizes Mineral-associated Organic Matter

Abstract Mineral-associated organic matter (MAOM) constitutes a major fraction of soil organic carbon and plays a critical role in long-term carbon sequestration. While factors like phosphate are known to destabilize MAOM, the role of dissolved inorganic carbon dominated by carbonate and bicarbonate remains underexplored.
