Dimethyl sulfide (DMS) is produced by plankton in oceans and constitutes the largest natural emission of sulfur to atmosphere. In this work, we examine new particle formation from primary pathway oxidation gas-phase DMS OH radicals. We particularly focus on growth mass yield as studied experimentally under dry conditions using atmospheric simulation chamber AURA. Experimentally, show that aeros...

Cl- efflux induces depolarization and contraction of smooth muscle cells. This study was undertaken to explore the role of Cl- channels in endothelin-1 (ET-1)-induced contraction in rabbit basilar artery. Male New Zealand White rabbits (n = 26), weighing 1.8-2.5 kg, were euthanized by an overdose of pentobarbital. The basilar arteries were removed for isometric tension recording. ET-1 produced ...

A novel serine pathway methylotroph, strain M2, capable of utilizing methanesulfonic acid (MSA) as a sole source of carbon and energy was investigated. The initial step in the biodegradative pathway of MSA in strain M2 involved an inducible NADH-specific monooxygenase enzyme (MSAMO). Fractionation of MSAMO active cell extracts by ion-exchange chromatography led to the loss of MSAMO activity. Ac...

During summer, the Southern Ocean is largely unaffected by anthropogenic emissions, which makes this region an ideal place to investigate marine natural aerosol sources and processes. A better understanding of key constrain preindustrial state reduce radiative forcing uncertainty in global climate models. We report concentrations gaseous sulfuric acid, iodic methanesulfonic acid (MSA) together ...

Herein, we report a convenient one-pot synthesis of 1,2,4-triazinyl derivatives benzocoumarins. The proposed approach consists in the nucleophilic addition tetrahydrobenzo annulated dimethoxycoumarin to 1,2,4-triazines followed by double oxidation both dihydrotriazine and groups with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ). was carried out presence three-fold excess methanesulfonic acid...
