Effects of UV-A Light Treatment on Ammonia, Hydrogen Sulfide, Greenhouse Gases, and Ozone in Simulated Poultry Barn Conditions

Atmosphere, 2020
Gaseous emissions, a side effect of livestock and poultry production, need to be mitigated to improve sustainability. Emissions of ammonia (NH3), hydrogen sulfide (H2S), greenhouse gases (GHGs), and odorous volatile organic compounds (VOCs) have a ...

A single cell death is disruptive to spontaneous Ca2+ activity in astrocytes

Frontiers in Cellular Neuroscience, 2022
Astrocytes in the brain are rapidly recruited to sites of injury where they phagocytose damaged material and take up neurotransmitters and ions to avoid the spreading of damaging molecules.

Diphenylcarbene Protected by Four ortho-Iodine Groups: An Unusually Persistent Triplet Carbene

Molecules, 2016
Diphenyldiazomethane with four iodine groups at the ortho positions and two tert-butyl groups at the para positions, i.e., bis(4-tert-butyl-2,6-diiodophenyl)diazomethane (1a-N2), was synthesized as a sterically hindered triplet carbene precursor ...

CO2‐to‐CO Electrochemical Conversion With an Fe(I) Porphyrin Complex in Water

Angewandte Chemie, EarlyView.
Using in situ UV–vis/IR spectroelectrochemistry, we track CO2 reduction by a water‐soluble iron porphyrin. Rather than the usual [Fe0] intermediate in organic solvents, CO2 binds the electrogenerated [FeI] species and undergoes reductive C─O cleavage to stable [FeII‐CO]. This previously unexplored reaction pathway is facilitated by an aqueous H‐bonding

Study on the Direct and Indirect Photolysis of Antibacterial Florfenicol in Water Using DFT/TDDFT Method and Comparison of Its Reactivity with Hydroxyl Radical under the Effect of Metal Ions

Toxics
Florfenicol (FLO) is a widely used antibacterial drug, which is often detected in the environment. In this paper, the photolysis mechanism of FLO in water was investigated using density functional theory (DFT) and time-dependent density functional theory
