Capacidade máxima de adsorção de fósforo relacionada a formas de ferro e alumínio em solos subtropicais Maximum phosphorus adsorption capacity as related to iron and aluminum forms in subtropical soils

Revista Brasileira de Ciência do Solo, 2010
O P é um dos macronutrientes primários essenciais para a produção vegetal. Apesar de ser o menos absorvido pelas plantas, é o mais utilizado nas adubações nos solos das regiões tropicais e subtropicais úmidas.

Moderate Fire Temperatures Affect the Structure of Clayey Oxisol Aggregates

Land Degradation &Development, Volume 37, Issue 8, Page 3169-3181, 15 May 2026.
ABSTRACT Wildfires have become increasingly frequent and intense worldwide, raising concerns about their impacts on soil systems. However, the thermal responses of clay‐rich Oxisols, dominated by Fe and Al oxides, remain poorly understood. In this study, samples from the 0 to 5 cm layer of six Oxisols were subjected to controlled heating at ...

Real‐time fault detection in multicomponent nuclear‐waste slurries through data fusion of spectroscopic sensors

AIChE Journal, Volume 72, Issue 5, May 2026.
Abstract Three instruments–Raman spectroscopy, attenuated total reflectance–Fourier transform infrared spectroscopy, and focused beam reflectance measurement–were used to detect sensor faults, mixing faults, and unanticipated chemistry in a system of multicomponent slurries.

An Integrated Chemicals‐Free Circular Model for Lithium Recovery From Spent Batteries to Direct Lithium Extraction From Brines

Battery Energy, Volume 5, Issue 3, May 2026.
A simple, chemical‐free method based on a 5‐min microwave treatment and using only water enables the synthesis of Li/Al layered double hydroxides (LDHs) from waste lithium‐ion batteries. These Li/Al LDHs can then be used for lithium extraction from primary resources, supporting a truly sustainable circular economy for lithium.

Lateritic Contribution to Enhancing the Grade of Iron Ore from Serra Leste Deposit in Carajás Mineral Province, Brazil

Mining
The Carajás Province, located in the southeastern Amazon, hosts some of the world’s largest high-grade iron deposits. Despite their economic importance, the processes linking lateritic weathering and iron enrichment remain incompletely understood.

Acid Leaching Performance of Gibbsite-type Bauxite with High Iron Content

Kuangchan zonghe liyong, 2022
High-iron bauxite with low A/S ratio cannot be extracted economically by Bayer process. Taking a low-grade gibbsite ore abroad as the research object, the acid leaching performance of gibbsite was studied by using hydrochloric acid as leaching medium ...

The master molecule that built biology: How water shaped the chemistry of life

Protein Science, Volume 35, Issue 5, May 2026.
Abstract The deep entanglement of biomolecular structure and function with aqueous systems supports the view that water actively sculpted both molecules and processes during the origins of life and continues to constrain evolution today. Nature's rules of biochemistry and biophysics have survived for nearly 4 billion years.

A soil sensing mechanism to reach carbon flux at a country scale

Soil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract Soil is the largest terrestrial carbon reservoir and can be a source or sink of CO2 for the atmosphere, depending on management practices. CO2 emissions from the soil surface (FCO2) are directly related to the biological and physicochemical soil properties. Our objective was to estimate and spatialize the net ecosystem production (NEP) for the
