Bacterial aerobic methane cycling by the marine sponge-associated microbiome

Microbiome, 2023
Background Methanotrophy by the sponge-hosted microbiome has been mainly reported in the ecological context of deep-sea hydrocarbon seep niches where methane is either produced geothermically or via anaerobic methanogenic archaea inhabiting the sulfate ...

Multiscale Perspectives on Perovskite Instability: From Atomistic Deformation to Device Degradation in Perovskite Solar Cells

Advanced Energy Materials, EarlyView.
Multiscale perspectives on how excess charges in soft lead halide perovskites induce operational instability in photovoltaic devices are presented. Localized carriers formed under thermodynamic non‐equilibrium states modify atomistic interactions and drive lattice distortions, accelerating device degradation.

Measurement of methylamines in seawater using solid phase microextraction and gas chromatography

, 2018
The methylamines form part of the marine organic nitrogen pool. Although they are ubiquitous in marine systems, little is known about their distribution, production and fate in the marine environment.

Trimethylamine N-oxide abolishes the chaperone activity of α-casein: an intrinsically disordered protein

Scientific Reports, 2017
Osmolytes (small molecules that help in circumventing stresses) are known to promote protein folding and prevent aggregation in the case of globular proteins. However, the effect of such osmolytes on the structure and function of intrinsically disordered

The effect of 3-nitrooxypropanol, a potent methane inhibitor, on ruminal microbial gene expression profiles in dairy cows

Microbiome, 2022
Background Enteric methane emissions from dairy cows are an environmental problem as well as a gross feed energy loss to the animal. Methane is generated in the rumen by methanogenic archaea from hydrogen (H2) + carbon dioxide and from H2 + methanol or ...

Symposium review: Understanding the role of the rumen microbiome in enteric methane mitigation and productivity in dairy cows

Journal of Dairy Science, 2022
: Ruminants are one of the largest sources of global CH4 emissions. This enteric CH4 is exclusively produced by methanogenic archaea as a natural product during microbial fermentation in the reticulorumen.

Sputtering Mechanism of an Unsintered Organic–Inorganic Sputtering Target for Perovskite Solar Cells

Advanced Energy Materials, EarlyView.
An unsintered MAPbI3 sputtering target fabricated via a mechanochemical route enables large‐area vacuum deposition of perovskite absorber layers, while revealing an ion–photon coupled decomposition mechanism that governs target erosion and film composition under RF plasma exposure.

Emissions of methylamines from cattle husbandry

, 2021
Gaseous amines play an important role in atmospheric chemistry, affecting both climate and human health. They act as precursors to particles and break down to form potentially toxic products.

One-pot two-step reduction of CO2 with amines and NaBH4 to N-substituted compounds at atmospheric pressure

Journal of CO2 Utilization
In this paper, the reductive N-formylation, methylation and cyclization of amines with carbon dioxide (CO2) using sodium borohydride (NaBH4) at atmospheric pressure, via a one-pot two-step procedure, is presented. Formato borohydride (NaBHn(OCHO)4-n), in

Characterization of Methanosarcina mazei JL01 Isolated from Holocene Arctic Permafrost and Study of the Archaeon Cooperation with Bacterium Sphaerochaeta associata GLS2^T

Proceedings, 2020
A mesophilic methanogenic culture, designated JL01, was isolated from Holocene permafrost in the Russian Arctic. After long-term extensive cultivation at 15 °C, it turned out to be a tied binary culture of archaeal (JL01) and bacterial (Sphaerochaeta ...
