Boron availability and fertilizer response of maize in soils from sub‐Saharan Africa

Journal of Plant Nutrition and Soil Science, EarlyView.
Abstract Background and aims Low boron (B) availability is associated with strongly weathered, coarse‐textured, and low organic matter soils, widespread in sub‐Saharan Africa (SSA). It is unknown to what extent B fertilization can increase maize yields in SSA.

Natural Colloids in Soil: Effect of Storage and Extraction Conditions on Colloid Amount and Composition

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Natural soil colloids (1–1000 nm) play a crucial role in the mobility and cycling of nutrients. In many studies, colloids are analyzed mainly as so‐called water‐dispersible colloids (WDCs), with varying storage and extraction steps.

Thermally Optimised Raman Spectroscopy for Safe Analysis of Wall Paintings and Application to Lorenzetti's Masterpiece

Journal of Raman Spectroscopy, EarlyView.
A portable dual‐wavelength Raman system (exc. 785 and 1064 nm) based on a four‐channel innovative probe for safe characterisation of artworks is presented. This instrument enables non‐contact real‐time monitoring of the temperature rise and laser power modulation to prevent overheating during Raman spectroscopy, through direct emissivity and ...

Improving the Raman Model for Dravite and Schorl Tourmalines by μXANES Analysis of Iron Oxidation States

Journal of Raman Spectroscopy, EarlyView.
By integrating μRaman and μXANES techniques, one can acquire insights into the oxidation state of iron in tourmalines from the dravite–schorl series, thereby enhancing the accuracy of the Mg/(Mg + Fe2+) ratio. The observed linear correlations for P2 peak position, P1/P2 relative intensities, and WOH(3) peak position in the Raman spectrum enable the ...

Raman Study of the Slobodka Ordinary Chondrite

Journal of Raman Spectroscopy, EarlyView.
The texture and mineral chemistry of Slobodka are most consistent with L4 chondrites, exhibiting strong shock metamorphism characteristic of shock stage S4, including irregular and planar fractures, undulatory extinction, and mosaicism in olivine, pyroxene, and plagioclase.

Soil carbon dioxide levels control salt marsh alkalinity generation

Limnology and Oceanography, EarlyView.
Abstract Recent studies have highlighted salt marshes as hotspots for alkalinity generation and export to coastal waters. Several studies emphasize the critical role of anaerobic microbial metabolism as a major source of total alkalinity (TA) generation in marsh soils. However, the contribution of mineral dissolution to salt marsh TA generation has yet

Pteropods as early‐warning indicators of ocean acidification

Limnology and Oceanography, EarlyView.
Abstract Aragonite undersaturation (Ωar$$ {\Omega}_{\mathrm{ar}} $$ <$$ < $$ 1) events are projected to rapidly increase in frequency and duration in the Antarctic Weddell Sea by 2050. Thecosome pteropods (pelagic snails) are bioindicators of ocean acidification (OA) because their aragonite shell dissolves easily at low Ωar$$ {\Omega}_{\mathrm{ar ...

In Vitro Behavior of Boron‐Doped Baghdadite/Poly(vinylidene fluoride) Membrane Scaffolds Produced via Non‐Solvent Induced Phase Separation

Macromolecular Bioscience, EarlyView.
Boron‐doped baghdadite (BAG)‐loaded polyvinylidene fluoride (PVDF) membrane scaffolds produced by non‐solvent induced phase separation (NIPS) show higher hydrophilicity, bioactivity and cancellous‐bone‐like mechanics. The scalable BAG/PVDF composites offer a versatile alternative to traditional bone grafts for regenerative medicine. Abstract This study

Biodegradable Polymers for Plant Nutrient Delivery and Recovery

Macromolecular Bioscience, EarlyView.
This review article discusses the use of biodegradable polymers to address several grand challenges in agriculture: to improve the delivery of nitrogen and phosphorous to crops, to optimize plant uptake, and to enhance the recovery of these nutrients from wastewater, to recycle them and reduce water pollution. Abstract The current use of fertilizers is
