Abstract Metal oxides are the key ingredients for development of many advanced functional materials and smart devices. Nanostructuring has emerged as one best tools to unlock their full potential. Tungsten (WO x ) unique that have been rigorously studied chromism, photocatalysis, sensing capabilities. However, they exhibit further important properties functionalities received relatively little attention in past. This Feature Article presents a general review nanostructured WO , properties,...
The limitation of hot spot cooling in microchips represents an important hurdle for the electronics industry to overcome with coolers yet exceed efficiencies required. Nanotechnology‐enabled heat sinks that can be magnetophoretically formed onto spots within a microfluidic environment are presented. CrO 2 nanoparticles, which dynamically chained and docked spots, establish tuneable high‐aspect‐ratio nanofins exchange between these liquid coolant. These also grown released on demand,...
Expanding the world of 2D materials Two-dimensional (2D) have a wide variety potential applications in electronics industry. However, certain compositions are difficult to obtain owing challenges exfoliating thin sheets from bulk crystals. Zavabeti et al. exploited liquid metals synthesize Ga 2 O 3 , HfO Gd and Al .

Nitrogen dioxide (NO2) is a gas species that plays an important role in certain industrial, farming, and healthcare sectors. However, there are still significant challenges for NO2 sensing at low detection limits, especially the presence of other interfering gases. The selectivity current gas-sensing technologies significantly traded-off with their sensitivity reversibility as well fabrication operating costs. In this work, we present progress selective reversible by demonstrating economical...

We demonstrate that the energy bandgap of layered, high-dielectric α-MoO(3) can be reduced to values viable for fabrication 2D electronic devices. This is achieved through embedding Coulomb charges within high dielectric media, advantageously limiting charge scattering. As a result, devices with ∼11 nm thickness and carrier mobilities larger than 1100 cm(2) V(-1) s(-1) are obtained.

In research on alternative photoanode materials for dye-sensitized solar cells (DSCs), there is rarely any report WO(3), probably due to its acidic surface and more positive (vs NHE) conduction band edge position compared TiO(2) ZnO. For the first time, based porous WO(3) nanoparticle films were successfully fabricated with efficiency of up 0.75%. The multicrystalline structure was examined by Raman spectroscopy X-ray diffraction analysis. It found that significant performance enhancement...
