Hydrogen transfer in hydrogen bonded solid state materials
The investigation of strongly hydrogen bonded solid state materials and the hydrogen transfer processes therein are the subject of the present work. Strong hydrogen bonds are found whenever the hydrogen bonded species compete for the hydrogen atom, and are thereby on the verge of showing hydrogen …

Development of a Hydrogen Producing Thermal Control for Chemical Hydrogen Storage
… thesis investigated a potential improvement to hydrogen storage for fuel cells using a thermally efficient hydrogen storage method. The efficiency of the storage system was improved using a metal hydride system to act as a thermal control unit for an exothermic chemical hydrogen storage system. …

Calculation involving hydrogen-hydrogen(2) collisional cooling processes for use in astrophysics
… The most abundant element in the universe is hydrogen, and cooling processes involving hydrogen are important in several contexts. To calculate the cooling, the cross section for collisional excitation at constant energy were integrated over a Maxwellian velocity distribution to determine a …

Production of uniform micropellets of hydrogen and hydrogen pellet injection on ORMAK
… was undertaken to determine the interaction of a hydrogen pellet with a high temperature plasma. An apparatus was developed which produced 70 micrometer diameter droplets of hydrogen by the acoustic disintegration of a liquid jet. The liquid drops were frozen and injected into vacuum at a speed of …

Hydrogen overvoltage on titanium
<p>"The hydrogen overvoltage has been defined as the difference between the potential of the working electrode (cathode) and the theoretical reversible value for the same solution. This definition brings out the difficulty involved in the measurement of the "theoretical reversible potential for the …

Exotic Species of Hydrogen
… triatomic molecule H3 and the negative ion of Hydrogen H-. These 'exotic' systems of Hydrogen are known to have a rather instable character due to their strong internal coupling and correlation phenomena. Their astrophysical significance and their role as exemplary cases in fundamental research …

Hydrogen Transport and Hydrogen Embrittlement in Stainless Steels (Diffusion, Permeation, Solubility, Slow Crack Growth)
In order to understand the kinetics of gaseous hydrogen-induced slow crack growth (SCG) in metastable austenitic stainless steels, hydrogen permeation and/or cracking velocity were measured and compared for three types of stainless steels. These included austenitic, ferritic, and duplex …

Studies of carbon-hydrogen and silicon-hydrogen bond activation by early transition metal complexes
Compounds that contain early transition metals particularly titanium, vanadium, and chromium, are used as catalysts for olefin polymerization in the Ziegler-Natta and Phillips processes. The key intermediates in these catalysts are thought to be six-coordinate metal alkyl/olefin complexes. The …
