A simple method to obtain homogeneous sub-monolayer coverage of metal oxide and chalcogenide nanocrystals onto porous oxide supports is described. Quantitative nanoparticle coverage was probed using photonic macroporous oxide supports. Composites of nanocrystals of TiO₂, Fe₃O₄ or CdS dispersed onto macroporous SiO₂ or ZrO₂ all show a predictable linear shift in the photonic stop band position.

Semiconductor nanocrystals are often proposed as a viable route to improve solar energy conversion in photovoltaics and photoelectrochemical systems. Embedding the in, e.g. transparent conducting electrode of cell will promote photon absorption subsequent transfer generated charge carriers from nanocrystal, thereby enhance function electrode. This can be accomplished by embedding semiconducting...

in this research, the inhibitory effects of silver nanoparticles and zinc oxide nanoparticles,  in vitro, on disease stone fruits bacterial canker caused by pseudomonas syrigae pv. syringae and disease bacterial blight caused by xanthomonas arboricola pv. juglandis, were studied. different concentrations of nanoparticles were prepared on mueller hinton agar medium in two different ways in a com...

This research was carried out to assessment agro physiological traits of bread wheat affected salinity stress, Nano zinc oxide and arbuscular mycorrhiza (AM) fungi under greenhouse condition via factorial experiment based on randomized complete blocks design with three replications. Experimental factors included salinity stress in three levels [no-salt (S0) or control, salinity 40 (S1), and 80 ...

Plant-mediated synthesis of metal oxide nanoparticles is a promising alternative to the traditional method of physical and chemical synthesis. In this paper, we report the green synthesis of zinc oxide nanoparticles (ZnONPs) by a biological method. During the study, Zinc oxide nanoparticles were synthesized by Allium sativum skin (garlic skin) extract. Formation of zinc oxide nanoparticles has ...

Hollow metal oxide nanocrystals were prepared by etching cuprous oxide with metal ions and were applied as photoelectrodes. As a hard template, polyvinylpyrrolidone stabilized cuprous oxide (PVP-Cu2O) and non-stabilized cuprous oxide (nPVP-Cu2O) were synthesized by a precipitation method. Hollow iron oxide and cobalt oxide nanocrystals with a truncated octahedral morphology were fabricated by a...

In order to compare the effects of different spraying of nano zinc oxide and zinc oxide, the arable irrigated wheat was conducted in two separate trials in 2011-2014 lands of Abadeh city.Experiments were conducted in a randomized complete block design, with five treatments and five replications.In the first experiment, treatments included the application of nano zinc oxide to five levels ( 0 , ...
