Chitin‐Derived Carbon‐Metal Functional Materials

Advanced Functional Materials, EarlyView.
Functional carbon materials are synthesized from combination of biopolymer (chitin) and iron precursors. The resultant material exhibits superior surface area and adsorptive properties compared to carbon materials synthesized directly from pure chitin.

Chronic pain relief after the exposure of nitrous oxide during dental treatment: longitudinal retrospective study

Arquivos de Neuro-Psiquiatria, 2015
The objective was to investigate the effect of nitrous/oxygen in chronic pain. Seventy-seven chronic pain patients referred to dental treatment with conscious sedation with nitrous oxide/oxygen had their records included in this research.

Uptake of nitrous oxide by man [PDF]

Canadian Anaesthetists’ Society Journal, 1982
Because of discrepancy in reports concerning the rate of uptake of nitrous oxide by man, it seemed desirable to measure this factor when automatic control of concentrations and rapid computer measurement of breath to breath uptake became available. Six subjects inhaled 25 per cent nitrous oxide for two hours.

Nitrous oxide: No laughing matter?

, 2020
Nitrous oxide (N2O) is a colourless gas discovered by Joseph Priestly in 1772. In human and veterinary medicine, it is used with oxygen as an anaesthesia due to its pain-relieving effects.

CO2‐to‐CO Conversion in a Gas‐Fed, Zero‐Gap, PEM Electrolyzer Enabled by Polycations and Nitrogen‐Doped Carbon‐Supported Cobalt Nanoparticles

Advanced Functional Materials, EarlyView.
A gas‐fed, zero‐gap, PEM CO2 electrolyzer is realized by incorporating PDDA+ ions onto the carbonaceous Co/N‐C electrocatalyst, with gaseous H2 and CO2 fed into the anode and cathode, respectively. Operating without an aqueous electrolyte, the system sustains a peak FECO of 65.1% at 100 mA cm−2. ABSTRACT Electrochemical carbon dioxide reduction (ECO2R)

Low-pressure storms drive nitrous oxide emissions in the Southern Ocean

Nature Communications
Nitrous oxide is a potent greenhouse gas and the primary ozone-depleting agent of the 21st century, but marine emissions of nitrous oxide remain difficult to constrain due to their spatiotemporal variability.

Covalent Functionalization of 2D Semiconductors: A Roadmap to Advanced Electronic Devices

Advanced Functional Materials, EarlyView.
This Review presents recent advances in the covalent functionalization strategies for two‐dimensional semiconductors and their implementation in modern technologies. Layered materials are modified through diverse molecular chemistries (e.g., thiols, diazonium salts, alkyl halides, and electron‐deficient species) to tailor their surface properties ...

Investigation of non-target gas interferences on a multi-gas cavity ring-down spectrometer

Atmospheric Environment: X
Emissions from agriculture are a worldwide problem as it is the major anthropogenic source of ammonia, methane, and nitrous oxide. Several efforts have been made to mitigate emissions.

Warming and redistribution of nitrogen inputs drive an increase in terrestrial nitrous oxide emission factor

Nature Communications, 2022
Soil nitrogen isotopic composition is used to drive the IsoTONE model, which is constrained with measurements of tropospheric nitrous oxide isotopic composition. The model results reveal causes of rising mean global nitrous oxide emission factor.
