In this work, a hydrothermal technique is employed to prepare titanium dioxide films on fluorine-doped tin oxide (FTO) substrates. A low-cost homemade autoclave was used fabricate iron-doped -TiO2 (1at. %Fe) at different reaction times from 1 4 hours. X-ray diffraction (XRD) patterns showed that the predominant phase rutile (R-TiO2) with peaks (101), (002), and (112). The XRD results increasing...

Branched Siloxane Brushes In article number 2301561, King Lun Yeung and co-workers develop a flexible hierarchically branched siloxane brushes by repeated grafting of on TiO2 nanorods. The facilitates water nucleation, while the structure promotes efficient droplet jumping. as-prepared surface displays significant improvement in harvesting at both high low humidity conditions, making it suitabl...

We propose a nano-scale current-direction-switching device(CDSD) that operates based on the novel phenomenon of geometrical asymmetry between two hot-electron generating plasmonic nanostructures. The proposed device is easy to fabricate and economical to develop compared to most other existing designs. It also has the ability to function without external wiring in nano or molecular circuitry si...

Narrow-band-gap semiconductor quantum dots (QDs) are considered as next-generation sensitizers for solar cells because of their extraordinary optical and electrical properties in terms of tuneable band gap, high molar extinction coefficient, and large intrinsic dipole moment, which may facilitate charge separation in solar cells. Moreover, theoretical photovoltaic conversion efficiency of QDs-s...

In the present work, we focused on geometrical (singleor double-tipped) and compositional (Pt or Au) variations of active metal components in a well-defined CdSe nanorod system. These colloidal nanostructures were employed for photocatalytic hydrogen generation from water under the identical reaction conditions with visible light irradiation. The catalysts exhibited significant dependency of th...

Coating titania shells onto sub-micron sized particles has been widely studied recently, with success mainly limited to objects with sizes above 50 nm. Direct coating on particles below this size has been difficult to attain especially with good control over properties such as thickness and crystallinity. Here we demonstrate that titanium-glycolate formed by reacting titanium alkoxide and ethyl...
