Thermal desorption spectroscopy studies of hydrogen desorption from rare earth metal trihydrides REH3 (RE¼Dy, Ho, Er)
(Journal of Alloys and Compounds, 2020)
Rare earth (RE) metals form two stoichiometric hydrides, REH2 and REH3, and for the yttrium group of RE transformation of a FCC (REH2) into an HCP (REH3) lattice takes place during the second step of hydrogenation REH2 þ ...
A review on crucibles for induction melting of titanium alloys
(Elsevier, 2020)
This review highlights the state of art progress in crucible designs which have been identified as showing potential for induction melting three groups of titanium alloys based on the systems; Ti–Al, Ti–Ni, as well as ...
Thermal conductivity and temperature profiles of the micro porous layers used for the polymer electrolyte membrane fuel cell
(Elsevier, 2013)
The thermal conductivity and the thickness change with pressure of several different
micro porous layers (MPL) used for the polymer electrolyte membrane fuel cell (PEMFC)
were measured. The MPL were made with different ...
Peroxide-based route for the synthesis of zinc titanate powder
(Elsevier, 2016)
In this work the thermodynamical solubility diagrams of zinc and titanium hydroxides
were reviewed in order to determine the conditions for maximum degree of phase composition
homogenization of precipitates. Experimental ...
Catalytic cracking of naphtha: The effect of Fe and Cr impregnated ZSM-5 on olefin selectivity
(Springer Nature, 2018)
This study focuses on the modification of ZSM-5 in order to enhance the catalytic cracking of refinery naphtha to produce
light olefins. ZSM-5 was metal modified using different loadings (0.5–5 wt%) of Fe and Cr via the ...
Preparation of iron molybdate catalysts for methanol to formaldehyde oxidation based on ammonium molybdoferrate(II) precursor
(Elsevier, 2016)
It was demonstrated that iron molybdate catalysts for methanol oxidation can be prepared
using Fe(II) as a precursor instead of Fe(III). This would allow for reduction of acidity of
preparation solutions as well as ...
The use of metal hydrides in fuel cell applications
(Elsevier B.V., 2017)
This paper reviews state-of-the-art developments in hydrogen energy systems which integrate fuel cells with metal hydride-based hydrogen storage. The 187 reference papers included in this review provide an overview of all ...
Characterization and activity test of commercial Ni/Al2O3, Cu/ZnO/Al2O3 and prepared NieCu/Al2O3 catalysts for hydrogen production from methane and methanol fuels
(Elsevier, 2013)
In this study, methane and methanol steam reforming reactions over commercial Ni/Al2O3, commercial Cu/ZnO/Al2O3 and prepared NieCu/Al2O3 catalysts were investigated. Methane and methanol steam reforming reactions catalysts ...
Beef-derived mesoporous carbon as highly efficient support for PtRuIr electrocatalysts and their high activity for CO and methanol oxidation
(SACI, 2014)
In this work, a low-cost and nitrogen-containing carbon with mesoporous pores and high surface area was synthesized by
carbonizing a natural biomass precursor, i.e. beef. It is found that the prepared material has excellent ...
Study of hydrogen storage properties of oxygen modified Ti- based AB2 type metal hydride alloy
(Elsevier, 2021)
A multi component AB2 type hydrogen storage intermetallic alloy (A = Ti0.85Zr0.15, B2 = Mn1.22Ni0.22Cr0.2V0.3Fe0.06; was investigated in this work. The intermetallic specified above was modified by oxygen to yield the ...
