3D Characterization of the Molecular Neighborhood of OH Radical in High Temperature Water by MD Simulation and Voronoi Polyhedra.

Understanding the properties of the OH radical in aqueous environments is essential for biochemistry, atmospheric chemistry, and the development of green chemistry technologies. In particular, the technological applications involve knowledge of microsolvation of the OH radical in high temperature water. In this study, the classical molecular dynamics (MD) simulation and the technique based on the construction of Voronoi polyhedra were used to provide 3D characteristics of the molecular vicinity of the aqueous hydroxyl radical (OH).

[Emergency care as a high-risk workplace-Measures to deal with violence against employees].

Background: Many employees in the field of emergency care experience verbal and physical violence caused by patients or visitors. The aim of this project is to gain insights into which measures are available to deal with violence in emergency care and how employees subjectively evaluate them.

Methods: A nationwide cross-sectional online survey was conducted in 2020.

Dynamics of Ion Pairing in Dilute Aqueous HCl Solutions by Spectroscopic Measurements of Hydroxyl Radical Conversion into Dichloride Radical Anions.

The rate of formation of dichloride anions (Cl) in dilute aqueous solutions of HCl (2-100 mmol·kg) was measured by the technique of pulse radiolysis over the temperature range of 288-373 K. The obtained Arrhenius dependence shows a concentration averaged activation energy of 7.3 ± 1.

Ergonomics in strabismus surgery.

Purpose Of Review: Although much has been written regarding ergonomics in ophthalmology, little information is available regarding the specific ergonomic concerns of pediatric ophthalmology and in particular, of strabismus surgery. This article will summarize current findings pertaining to musculoskeletal disorders in ophthalmology and review their implications for strabismus surgeons.

Recent Findings: Optical motion capture is a promising alternative to older qualitative and quantitative methods for evaluating ergonomic posture.

Ionic-Equilibrium-Based Mechanism of OH Conversion to Dichloride Radical Anion in Aqueous Acidic Solutions by Kinetic and Theoretical Studies.

A new mechanism for the dichloride radical anion (Cl) formation in diluted acidic chloride solutions is proposed on the grounds of pulse radiolysis measurements of the optical absorption growth at 340 nm and the density functional theory and Hartree-Fock computations. We show that the rate of OH conversion into Cl is determined by the equilibrium concentration of the ionic pair HO·Cl. According to the proposed mechanism, the diffusional encounter of OH and HO·Cl is followed by fast concerted charge/proton transfer ( k(25 °C) = 6.
