Phylogenomic Reconstruction and Metabolic Potential of the Genus Aminobacter

open access: yesMicroorganisms, 2021
Bacteria belonging to the genus Aminobacter are metabolically versatile organisms thriving in both natural and anthropized terrestrial environments. To date, the taxonomy of this genus is poorly defined due to the unavailability of the genomic sequence ...

Designed Lewis Acid–Base Passivation for High Performance Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Silicon's high cost and long energy payback time remain major barriers to the global expansion of solar power. In contrast, metal–halide perovskites offer abundant, solution‐processable absorbers, and have achieved efficiencies of 25%–30%, positioning them as strong competitors to silicon.

Urea and methylamines have similar effects on aldose reductase activity

open access: yes, 1997
The concentration of urea in renal medullary cells is sufficiently high to inhibit activity of many enzymes, yet the cells survive and function. The generally accepted explanation is the counteracting osmolytes hypothesis, which holds that methylamines ...

Capacity for Cellular Osmoregulation Defines Critical Salinity of Marine Invertebrates at Low Salinity

open access: yesFrontiers in Marine Science, 2022
Low-salinity stress can severely affect the fitness of marine organisms. As desalination has been predicted for many coastal areas with ongoing climate change, it is crucial to gain more insight in mechanisms that constrain salinity acclimation ability ...

Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

open access: yesAdvanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

A Cu‐Based Near‐IR Active MOF with an Ion‐Pair Guest Exhibiting Versatile and Selective Gas‐Solid Reactivity

open access: yesAdvanced Materials, EarlyView.
The new Cu‐containing MOF (Me2NH2)(CuICl2)@[Cu4(INA)4Cl2O]·1.5dmf (3) contains a cation and an anion as guests and shows UV‐near‐mid‐IR absorption and near‐IR emission. MOF 3 shows gas‐solid reactivity in the presence of NH3 and HCOOH to yield two new 3D MOF.

Thin Layer Chromatography of Methylamines in Fish and Marine Products. [PDF]

open access: yes, 1966
The technique of thin layer chromatography was studied as one of the methods to analyze methylamines and trimethylamine-N-oxide. Methylamines and trimethylamine oxide, which are difficult to separate in their free form or salt, were successfully ...

A Quantitative Method to Measure and Speciate Amines in Ambient Aerosol Samples

open access: yesAtmosphere, 2020
Ambient reactive nitrogen is a mix of nitrogen-containing organic and inorganic compounds. These various compounds are found in both aerosol- and gas-phases with oxidized and reduced forms of nitrogen.

Ideas and perspectives: on the emission of amines from terrestrial vegetation in the context of new atmospheric particle formation [PDF]

open access: yesBiogeosciences, 2015
In this article we summarise recent science which shows how airborne amines, specifically methylamines (MAs), play a key role in new atmospheric particle formation (NPF) by stabilising small molecule clusters.
