Acute psychotic and vitamin B12 deficiency in patient with nitrous oxide misuse: A case report

SAGE Open Medical Case Reports
Nitrous oxide, also called nitrous monoxide, or nitrous oxide, is a colorless and odorless gas, without toxicological effect, but it can be asphyxiating at high concentration, its misuse is increasing especially among young people.

Ammonium Salts as Curing Agents to Obtain Ionic Epoxy Resins With a Thermoplastic‐to‐Thermoset Transition

Advanced Materials, EarlyView.
Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.

A Nano‐Interception Strategy for Chronic Heart Failure: Prussian Blue Nanoparticles Disrupt Fibroblast‐Immune Communication via CCL2 Sequestration

Advanced Materials, Volume 38, Issue 31, 2 June 2026.
A nano‐interception strategy disrupts pathogenic fibroblast–macrophage crosstalk in chronic heart failure. Scalable Prussian blue nanoparticles selectively sequester CCL2 via ultrahigh‐affinity binding, preventing CCR2+ macrophage recruitment and breaking a key fibro‐inflammatory circuit. This approach demonstrates robust efficacy in murine and porcine

Laughing gas abuse causing subacute combined spinal cord degeneration with psychiatric manifestations [PDF]

Romanian Journal of Neurology
Background. Nitrous oxide, a nonirritating gas commonly used as an anesthetic, is increasingly abused by the young population for its euphoric effects due to its seemingly harmless nature.

Composition Restoration Enables Recycling of Mixed‐Cation, Mixed‐Halide Perovskites for Solar Cells

Advanced Materials, EarlyView.
Compositional drift during processing prevents the direct recycling of mixed‐cation, mixed‐halide perovskites. This work introduces a framework to quantitatively audit and restore recovered materials, enabling closed‐loop recycling with efficiencies comparable to virgin perovskites.

Characterization and Antimicrobial Activity of Hafnium Nanostructures Fabricated by Physical Vapor Deposition Through a Colloidal Mask

Advanced Materials Interfaces, EarlyView.
We generate hafnium nanostructures by first depositing polystyrene particles of varying diameter followed by physical vapour deposition of hafnium thin films. The resultant structure shows a kill‐on‐contact effect against both Gram‐negative Escherichia coli and Gram‐positive Staphylococcus aureus.

Generation of Nitrous Oxide by Aerobic Denitrifiers Isolated from an Urban Wetland in Bogotá, Colombia

Limnological Review
In this study, we evaluated the nitrous oxide production potential of denitrifying bacterial strains isolated from sediments of the urban wetland Santa María del Lago under anaerobic and aerobic conditions to determine their potential role in mitigating ...

Nitrous oxide emissions from organic farming: the importance of well-timed ley cultivation [PDF]

, 2006
The period after ploughing of grass-clover within a ley-arable rotation is when nitrogen accumulated during ley cropping is most vulnerable to loss. I investigated how date of ploughing and date of cessation of grazing before ploughing influenced losses ...

Impact of Oxygen Plasma Pre‐Treatment on Thermal Oxidation and Reliability of SiO2 on 4H‐SiC

Advanced Materials Interfaces, EarlyView.
We investigate how oxygen plasma pre‐treatment affects the thermal oxidation of silicon carbide. While plasma modification increases growth rates by 84%, it reduces dielectric breakdown strength by 18%. Our findings reveal that although plasma improves the interface state density, it introduces structural damage, highlighting a critical trade‐off ...
