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 , ...

Spontaneous deposition of Pt on a Ru(0001) single crystal surface has been demonstrated by in situ scanning tunneling microscopy and linear sweep voltammetry techniques. The immersion of a ultra-high vacuum (UHV) prepared Ru single crystal in a platinum-ion-containing solution results in the formation of monolayer-to-multilayer Pt deposits without application of an external potential. The cover...

NiFe/NiFeOx core/shell electrocatalysts show excellent OER activity by taking advantage of the synergetic effect between the metal core and the oxide/hydroxide shell, i.e. the metal core provides good bulk electron conduction and thus extends the OER active sites to the whole oxide/hydroxide shell, and the shell catalyzes the OER and protects the metal core from oxidation.

There are numerous potential uses as nanoparticles produced from green methods in the medicinal and environmental sciences with a reduction of harmful chemicals solvents. To synthesize use safe organic resources like plants, microorganisms producing for applications such catalysis, sensing, electronics, photonics medicine. Aiming to minimize or prevent waste generated reactions while maintainin...

Carbon graphitic structures that differ in morphology, graphiticity and specific surface area were used as support for platinum for Oxygen Reduction Reaction (ORR) in low temperature fuel cells. Graphitic supports were first non-covalently functionalized with pyrene carboxylic acid (PCA) and, subsequently, platinum nanoparticles were nucleated on the surface following procedures found in previo...

Searching for novel electrocatalysts that can replace precious platinum oxygen reduction reaction (ORR) is important developing fuel cells. Recently, nitrogen (N) doped graphdiyne (GDY) has been synthesized and...

optical modeling was applied for obtaining absorbance spectra and band gap values for different morphology of zno semiconductor. in optical modeling, the relative permittivity scalars of zinc oxide coral like nanorods were calculated using the bruggeman homogenization formalism. zno nano rods (zonrs) as a nucleus layer were fabricated on the indium tin oxide (ito) by chronoamperometry (ca) in a...
