Metal–Organic Frameworks for Gaseous Pollutant Management: From Capture to Neutralization and Reutilization

Advanced Functional Materials, EarlyView.
This review maps how MOFs can manage hazardous gases by combining adsorption, neutralization, and reutilization, enabling sustainable air‐pollution control. Covering chemical warfare agent simulants, SO2, NOx, NH3, H2S, and volatile organic compounds, it highlights structure‐guided strategies that boost selectivity, water tolerance, and cycling ...

Experimental study on the extraction of niobium from crude niobium ore by KOH hydrothermal

矿业科学学报, 2017
Because the crude niobium ore is difficult to be used, according to the composition analysis and phase analysis of crude niobium ore, the KOH hydrothermal method was used to research the dissolution of crude niobium ore and the dissolution of crude ...

Seeps and Tectonic Structure of the Hydrothermal System of the Panarea Volcanic Complex (Aeolian Islands, Tyrrhenian Sea)

Geosciences
High-definition bathymetry mapping, combined with the measurement of dissolved benthic fluxes and water column biogeochemical properties, allows for a description of new biogeochemical processes around the Panarea Volcanic island.

A thermodynamic basis for prebiotic amino acid synthesis and the nature of the first genetic code

, 2009
Of the twenty amino acids used in proteins, ten were formed in Miller's atmospheric discharge experiments. The two other major proposed sources of prebiotic amino acid synthesis include formation in hydrothermal vents and delivery to Earth via meteorites.

Where Most Frameworks Degrade: Flexible Bimetallic Phosphonate Crystals as pH‐Universal Supercapacitor Electrodes

Advanced Functional Materials, EarlyView.
Plastically flexible single crystals of the bimetallic phosphonate framework [Cu(2,2′‐bpy)VO(O3PC6H5)2] combine mechanical adaptability with robust pseudocapacitive charge storage. The material delivers about 140 Fg−1 at pH 4 and pH 10 and remains stable across pH 2‐12, enabling energy storage under comparatively mild electrolyte conditions.

Estudo da Influência do Tempo de Síntese na Obtenção de Hidroxiapatita por Hidrotermal/micro-ondas

Orbital: The Electronic Journal of Chemistry, 2014
The hydrothermal system has been widely used in recent years for the synthesis of materials, especially in the synthesis of nanostructured materials. The present work aimed to synthesize hydroxyapatite, since it is characterized by being a biomaterial ...

Bone Healing Around Implants in Normal and Medically Compromised Conditions: Osteoporosis and Diabetes

Advanced Healthcare Materials, EarlyView.
xx xx. ABSTRACT Osseointegration of orthopedic and dental implants is influenced by local and systemic factors, including their physicochemical surface properties and the patient's overall health status. Titanium and its alloys have been a longstanding standard for bone implants due to their innate biocompatibility and mechanical properties.
