Triatomic Hydrogen and Doppler Effect in Hydrogen Positive Rays
Nature, 1947J. J. THOMSON1 discovered the triatomic molecule of hydrogen by the positive ray parabolic method. It was later confirmed by Dempster2, Duane and Wendt3, and several others. Its occurrence is very frequently noted in discharge tubes, but the optimum conditions are not well defined. While investigating the Doppler effect in hydrogen positive rays, using

Protective Effects of Hydrogen against Irradiation
Current Pharmaceutical Design, 2021Radiation-induced lung injury is characterized by an acute pneumonia phase followed by a fibrotic phase. At the time of irradiation, a rapid, short-lived burst of reactive oxygen species (ROS) such as hydroxyl radicals (•OH) occurs, but chronic radiation-induced lung injury may occur due to excess ROS such as H2O2, O2•−, ONOO−, and •OH.

Abstract The effect of hydrogen on the physical properties of copper is considered with emphasis on determining which form of hydrogen is responsible for the property change. Three situations in which the properties of copper are known to be affected by hydrogen are (1) thermal charging, (2) cathodic charging and (3) electroless copper plating. It is

Effect of Hydrogen Plant Structure on Hydrogen Diffusion
Volume 10: Risk Assessments and Management; Computer Code Verification and Validation; Nuclear Education and Public AcceptanceAbstract Nuclear energy is a primary energy source that is low in carbon and highly efficient. The hydrogen production process coupled with nuclear power produces clean, low-carbon, and highly efficient hydrogen. However, hydrogen leakage accidents may occur during the hydrogen production process, and the structural design of hydrogen ...

Journal of the American Chemical Society, 2007
A combined kinetic and DFT study of the uncatalyzed isomerization of cationic solvent complexes of the type cis-[Pt(R')(S)(PR3)2]+ (R' = linear and branched alkyls or aryls and S = solvents) to their trans isomers has shown that the reaction goes through the rate-determining dissociative loss of the weakly bonded molecule of the solvent and the ...

Hydrogenation of Magnesium Nanoblades: The Effect of Concentration Dependent Hydrogen Diffusion
Volume 4: Energy Systems Analysis, Thermodynamics and Sustainability; Combustion Science and Engineering; Nanoengineering for Energy, Parts A and B, 2011By assuming the H diffusion coefficient and H adsorption rate to be exponentially and linearly dependent on H concentration, a physical model is developed to predict the hydrogenation process of Mg nanoblades. The predicted H uptake curves agree well with the experimental data from V-coated Mg nanoblades.

Micellar effect on the photolysis of hydrogen peroxide
Water Research, 2001Photolysis experiments were performed to quantify the effect of three anionic surfactants on the photolysis of hydrogen peroxide (H2O2) at the ambient laboratory temperature of 22+/-1 degrees C. H2O2 photolysis in water, methanol, and surfactant monomeric solution was also conducted to compare the photochemical reactivity of H2O2 in different media ...

Hydrogen effects on a-SiO2: A photoemission study
Journal of Non-Crystalline Solids, 1991Negative bias stress experiments on a-Si:H/a-SiO 2 Thin Film Transistors show that the instability is predominantly related to charge injection in the gate insulator. We propose that charge injection is occurring in a defected region of the gate insulator adjacent to a-Si:H, caused by the effect of activated hydrogen on a-SiO 2 surface during ...

Hydrogen Effects on Plasticity
2000In this paper, we will focus on the influence of solute hydrogen on dislocation behavior and the manifestation of these effects on the plastic deformation of solids. The paper will review the literature and will present some mechanistic approaches that will allow the rationalization of the very diverse set of observations.

Hydrogen bonds are characterized by interaction energies in the range from 5 to 30 kJ/mol. The following energetic characteristics can be extracted from the literature: For the weakest C–H\(\cdot \)N and C–H\(\cdot \pi \) interactions, 6.28–10.47 kJ/mol; for N–H\(\cdot \)O, N–H\(\cdot \)N, O–H\(\cdot \)O, and O–H\(\cdot \)N, 12.57–29.33 kJ/mol.
