Abstract 1D metal‐oxide nanostructures have attracted much attention because metal
oxides are the most fascinating functional materials. The 1D morphologies can easily …

We report the fabrication of vertically aligned NiO nanowalls on nickel foils using a plasma
assisted oxidation method. Electrochemical properties of as-synthesized NiO nanowalls …

Many-body GW calculations have emerged as a standard for the prediction of band gaps,
band structures, and optical properties for main-group semiconductors and insulators, but it …

The doping response of the prototypical transparent oxides NiO (p-type), ZnO (n-type), and
MgO (insulating) is caused by spontaneous formation of compensating centers, leading to …

This paper deals with a significant family of compounds predicted by simplistic electronic
structure theory to be metals but are, in fact, insulators. This false metallic state has been …

Vanadium dioxide (VO2) is a well-known semiconductor material with a band gap of 0.7 eV,
and is seldom used as a photocatalyst. We report here a new crystal structure for …

Nickel oxide (NiO) thin films were deposited onto quartz substrates by the electron beam
deposition technique, and obtained high crystal quality after annealing at 1173 K. The …

An improved corona discharge ignited by oxide cathodes (MgO/NiO/Ni cathode and NiO/Ni
cathode) with high secondary electron emission is proposed for toluene degradation. The …

Miniaturized, wearable and self-powered sensors are crucial for applications in artificial
intelligence, robotics, healthcare, and communication devices. In particular, piezoelectric …

When heated in a rapid thermal processor at 350 C in air, cobalt thin (50 nm thick) films were
transformed into Co 3 O 4 nanorods in minutes. The nanorods are single-crystalline and are …
