A perovskite solar cell is produced using the scalable technique aerosol-assisted chemical vapour deposition for first time. This achieved by a 2-step process with lead acetate as source and methanol solvent.

Apple growers face new challenges to produce organic apples and now many cover orchards with high-density polyethylene (HDPE) nets to exclude insects, rather than spraying insecticides. However, rainwater- associated wetness favours the development of apple scabs, Venturia inaequalis, whose lesions accumulate on the leaves and fruit causing unsightly spots. Treating the nets with a superhydroph...

A ubiquitous goal in plasma-enhanced chemical vapour deposition (PECVD) is to describe the correlation between film properties and categorical and quantitative input variables. The correlations within the high-dimensional parameter space are described using a multivariate model. Bayesian group analysis is employed to assess the grouping structures of the set of data vectors. This allows to iden...

This article presents a review of recent research efforts and developments for the fabrication of metal-oxide gas sensors using chemical vapour deposition (CVD), presenting its potential advantages as a materials synthesis technique for gas sensors along with a discussion of their sensing performance. Thin films typically have poorer gas sensing performance compared to traditional screen printe...

The atmospheric pressure chemical vapour deposition (APCVD) reaction of VCl4 and VOCl3 with cyclohexylphosphine at substrate temperatures of 600 C deposits thin films of amorphous vanadium phosphide. The films are black/gold, hard, chemically resistant and conductive. The APCVD reaction of MCl5 (where M = Nb or Ta) with cyclohexylphosphine at 500 C – 600 C deposits films of crystalline -MP ...

This work reports on recent advances in the deposition of non-wettable coatings with high water contact angles (WCAs). We propose a simple and easily-controlled method for fabricating different types of nanoestructured films of Al2O3 with hydrophobic properties by Physical Vapour Deposition (PVD). The films have been deposited over three types of hydrophilic substrates with very different value...

Tin nitride (Sn(x)N(y)) nanowires have been grown for the first time by chemical vapour deposition on n-type Si(111) and in particular by nitridation of Sn containing NH(4)Cl at 450 degrees C under a steady flow of NH(3). The Sn(x)N(y) nanowires have an average diameter of 200 nm and lengths >/=5 mum and were grown on Si(111) coated with a few nm's of Au. Nitridation of Sn alone, under a flow o...

Chemical vapour deposition on a Cu substrate is becoming a very important approach to obtain high quality graphene samples. Previous studies of graphene growth on Cu mainly focus on surface processes. However, recent experiments suggest that gas-phase dynamics also plays an important role in graphene growth. In this article, gas-phase processes are systematically studied using computational flu...
