Screening parameters for the relativistic hydrogenic model
(Elsevier, 2015-08)
We present a Relativistic Screened Hydrogenic Model (RSHM) where the screening parameters depend on the variables ( ) nl j, and the parameters ( ) Z N. These screening parameters were derived theoretically in a neat form ...
The combined use of screening and quantum defect parameters in the study of ionized atoms
(Elsevier, 2015-03)
The screened hydrogenic model (SHM) is one of the atomic models commonly used in plasma physics, especially in the high energy density range. However, for low-ionization degrees, the radial hydrogenic wavefunctions of the ...
Experimental and theoretical study of the behavior of hydrogen in rare earths
(Pergamon-Elsevier Science Ltd, 2005-05-13)
In this work, we study the behavior of hydrogen in some rare earths lanthanum (La), cerium (Ce), lutetium (Lu), and in two of its chemical precursors, scandium (Sc) and ytrium (Y). In the experimental aspect, samples of ...
Design of high entropy alloys for hydrogen storage: study of the Mg-V-Al-Cr-Ni, Mg-Al-Ti-Mn-Nb and Ti-V-Nb-Cr systems
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2021-05-21)
The advent of high entropy alloys (HEA) has brought new opportunities and challenges to metallurgy. Due to extensive compositional field of HEAs, the possibility of controlling properties in a composition-driven approach ...
Thermodynamic Stabillity of Hydrogen-Bonded Systems in Polar and Nonpolar Environments
(JOHN WILEY & SONS INC, 2010)
The thermodynamic properties of a selected set of benchmark hydrogen-bonded systems (acetic acid dimer and the complexes of acetic acid with acetamide and methanol) was studied with the goal of obtaining detailed information ...
Screening Brazilian commercial gasoline quality by hydrogen nuclear magnetic resonance spectroscopic fingerprintings and pattern-recognition multivariate chemometric analysis
(Elsevier B.V., 2010-06-30)
The identification of gasoline adulteration by organic solvents is not an easy task, because compounds that constitute the solvents are already in gasoline composition. In this work, the combination of Hydrogen Nuclear ...
Simulation and response surface analysis for the optimization of a three-phase catalytic slurry reactor
(Elsevier Science SaLausanneSuíça, 2005)
Ligand and structure-based modeling of passive diffusion through the blood-brain barrier

Voltammetric and Scanning Electrochemical Microscopy Investigations of the Hydrogen Evolution Reaction in Acid at Nanostructured Ensembles of Ultramicroelectrode Dimensions: Theory and Experiment
(American Chemical Society, 2018-01)
Mechanistic studies of the hydrogen evolution reaction (HER) on nanoelectrode ensembles of ultramicroelectrode dimensions (UME-NEEs) are demonstrated using addressable nanoelectrode membrane arrays (ANEMAs). A kinetic model ...
