Gaseous mediators (H2S, NO and CO) a new approach in gastrointestinal protection

open access: yesMexican Journal of Medical Research ICSA, 2023
Gastrointestinal damage is generated by a wide range of harmful agents, and is the result of the activation of inflammatory, oxidant and cytotoxic mechanisms, that together overwhelm the “mucosa defense” of the gastrointestinal (GI) tract.

The Influence of Ni Content in NixCoy‐BDC Metal‐Organic Frameworks on Catalytic Activity for Hydrogen Generation from Sodium Borohydride

open access: yesChemCatChem, Volume 18, Issue 11, 15 June 2026.
ABSTRACT Mono‐ and bimetallic Ni/Co‐based metal–organic frameworks (MOFs) coordinated with 1,4‐benzenedicarboxylate were successfully synthesized via a solvothermal approach and characterized by PXRD, FTIR, TGA, SEM–EDS, TEM, BET, and XPS. Fine control over the Ni:Co molar ratio enabled systematic modulation of the structural and electronic properties ...

Hyperbaric treatment for acute carbon monoxide poisoning in a patient with beta-thalassemia. [PDF]

open access: yesPediatric Anesthesia and Critical Care Journal (PACCJ)
Carbon monoxide (CO) poisoning is a rare but potentially devastating event and remains the most common cause of poisoning in developed countries. Diagnosis is often missed or delayed, as the clinical presentation can be highly variable and characterized ...

Magnetic Nanoparticles: Co@SiO2, Co@Au and Co@Pt

open access: yesEclética Química Journal, 2017
Nanotechnology is the understanding and control f matter at dimensions of roughly 1 – 100 nm. At the nanoscale, the properties like electrical conductivity and mechanical strength are not the same as the materials with particles in dimensions much more than 100 nm. The electronic structure changes dramatically too.

Electrochemical Corrosion Resistance of Ni and Co Bonded Near-Nano and Nanostructured Cemented Carbides

open access: yesMetals, 2020
The advantages of nanostructured cemented carbides are a uniform, homogenous microstructure and superior, high uniform mechanical properties, which makes them the best choice for wear-resistant applications.

Ceria‐Zirconia Supported Gold Nanoparticles for CO and Soot Oxidation

open access: yesChemCatChem, Volume 18, Issue 9, 14 May 2026.
ABSTRACT This study introduces a gold nanoparticles catalyst (AuNPs) supported on ceria‐zirconia oxide, prepared by deposition‐precipitation (Au/CZ‐dep) and chemical reduction (Au/CZ‐red). The as‐prepared catalysts were tested in CO oxidation by O2 and soot oxidation under different oxidizing atmospheres (O2, NO2+NO+O2).
