Thermoelectric Power and Electrical Resistance of Hydrogenated Nickel Alloyed with Transition Metals (V, Fe, Co) between 80 and 300 K

An infrared imaging method for high-throughput combinatorial investigation of hydrogenation-dehydrogenation and new phase formation of thin films

“…The absorption of hydrogen in metals and alloys results in new scattering centers and eventually leads to a modified density of states, which is often accompanied by a rise in the Fermi energy E f . [33][34][35][36] The shift in E f to an energy with a lower density of states leads to a less metallic character and there-fore an increase in the electrical resistance or change in conductivity from metallic to insulating. Thus IR emissivity is expected to increase with the increase in hydrogen in a material.…”

Influence of hydrogen on electron transport of palladium alloyed with silver

“…Thermoelectric power, S, and electrical resistance, r, of one-and two-phase samples, as received after hydrogen loading (labeled "1" on figures) and after successive partial hydrogen desorptions (labeled "2", "3", etc), have been measured simultaneously in the temperature range between 80 and 300 K. The lowest hydrogen contents have been achieved by heating the samples up to 340 K. More experimental details can be found in [5] and [8].…”

Parallel Simulations of Relaxation in Electron Transport in Crossed Electric and Magnetic Fields

“…c-values lower than about 0.6 correspond to the two-phase composition, α-(PdMe)H c α + β-(PdMe)H c β , where c α ≈ 0.03-0.05 and c β ≈ 0.5-0.6. More experimental details can be found in [7] and [9]. Separate measurements of electrical resistance of the hydrogenated alloys have been performed in the low-temperature region (1.5-300 K).…”

“…In this paper we check the influence of additions of Ru and Rh, elements standing to the left of palladium, on the TEP of β-phase palladium hydride (PdH c , 0.6 c 1). Recently a marked influence of the additions of metals standing in the table of elements to the left of nickel (V, Cr, Fe, Co) on the TEP of nickel hydride, an analogue of the noble metal copper, was reported [7,8].…”
