Nickel-titanium-oxide (Ni-Ti-O) nanotube arrays (NTAs) prepared on nearly equiatomic NiTi alloy shall have broad application potential such as for energy storage and biomedicine, but their precise structure control is a great challenge because of the high content of alloying element of Ni, a non-valve metal that cannot form a compact electronic insulating passive layer when anodized. In the pre...

A Fluidized Bed Metal–Organic Chemical Vapor Deposition (FB-MOCVD) process was developed for the growth of tin oxide thin films on large hollow Ni particles. Tetraethyl tin was used as tin source and dry air both as fluidization gas and oxidant reagent. The SnO2 films were grown in a FBCVD reactor under reduced pressure (13.3 kPa) in the temperature range of 633–663 K. A series of specific expe...

A novel selective and sensitive electrochemical sensor for insulin detection has been fabricated and investigated. The electrochemical sensor was made from a mixture of silica gel, chitosan and nickel hydroxide (Ni(OH)2) nanoparticles, which was mounted on a silver wire and covered by a glass tube (silica gel/chitosan/Ni(OH)2 nanoparticles paste electrode). The sensor was characterized using cy...

Mixed ionic electronic conductors (MIECs) have attracted increasing attention as anode materials for solid oxide fuel cells (SOFCs) and they hold great promise lowering the operation temperature of SOFCs. However, there has been a lack understanding performance-limiting factors guidelines rational design composite metal-MIEC electrodes. Using newly-developed approach based on 3D-tomography elec...

An experimental analysis was performed to optimize the structure of Ni–Ni(OH)2/NiO core-shell nanowire electrodes for improving their application in pseudocapacitors. Thickness and composition active phase shell were compared after thermal treatments at 40, 70 300 °C. A Ni(0) core found by XPS electrode treated 40 °C, it still present a temperature increase °C but with lower Ni(OH)2/NiO ratio s...
