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 ...
Hydrides of Laves type Ti–Zr alloys with enhanced H storage capacity as advanced metal hydride battery anodes
(Elsevier, 2020)
The present work was focused on the studies of the effect of variation of stoichiometric composition of Ti–Zr based AB2±x Laves phase alloys by changing the ratio between A (Ti + Zr) and B (Mn + V + Fe + Ni) components ...
Metal hydride hydrogen storage tank for fuel cell utility vehicles
(Elsevier, 2020)
The “low-temperature” intermetallic hydrides with hydrogen storage capacities below 2 wt% can provide compact H2 storage simultaneously serving as a ballast. Thus, their low weight capacity, which is usually considered as ...
Microalgae as a biocathode and feedstock in anode chamber for a self-sustainable microbial fuel cell technology: A review
(Elsevier, 2020)
Microbial fuel cell (MFC) technology has been investigated for over a decade now and it has been deemed as a preferred technique for energy generation since it is environmentally benign and does not produce toxic by/end ...
Development of FeCux/FeS/Graphite composite electrode materials for iron-based Alkaline batteries
(Electrochemical Science Group, University of Belgrade, 2020)
In an attempt to enhance the electrochemical performance of the iron-based electrode, an iron-core copper-shell nano-structured material was synthesized and incorporated with ferrous sulphide, and graphite additives. An ...
A comprehensive review on hydrogen absorption behaviour of metal alloys prepared through mechanical alloying
(MDPI, 2020)
Hydride-forming alloys are currently considered reliable and suitable hydrogen storage materials because of their relatively high volumetric densities, and reversible H2 absorption/desorption kinetics, with high storage ...
Hollow-structured NiCoP nanorods as high-performance electrodes for asymmetric supercapacitors
(Elsevier, 2020)
One-dimensional hollow-structured NiCoP nanorods are synthesized via Kirkendall effect resulting from different diffusion rates of Ni and Co ions at 350 °C, using NaH2PO2 as a phosphorization agent. Various techniques were ...
Optimal design of combined two-tank latent and metal hydrides-based thermochemical heat storage systems for high-temperature waste heat recovery
(Multidisciplinary Digital Publishing Institute (MDPI), 2020)
The integration of thermal energy storage systems (TES) in waste-heat recovery applications
