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...

zno plays an important role in many semiconductors technological aspects.  here,  direct  precipitation  method  was  employed  for  the synthesis of nano-sized hexagonal zno particles, which is based on chemical  reactions between  raw materials used  in  the  experiment. zno  nanoparticles  were  synthesized  by  calcinations  of  the  zno precursor precipitates  at 250  ˚c  for 3hours. the p...

The supramolecular coordination of zinc (II) phthalocyanine (Zn-Pc) with V-shaped bi-pyridine in a nano-reactor is probed by scanning tunneling microscopy (STM) at liquid/solid interface. Combined with density functional theory (DFT) calculations, our STM results show that the V-shaped bi-pyridine and Zn-Pc can generate stable "odd-even" patterned architectures in the TCDB network through a two...

in this research, acute toxicity (lc) of zinc oxide nanoparticle on beluga (huso huso) andcommon carp (cyprinus carpio) was studied. the experiment was conducted using theorganization for economic co-operation and development (no. 202) method. for bothspecies, 96hlc10 was determined to be more than 200 mg/l. to assess the effects of zinc oxidenanoparticles on blood factors, leukocyte index coun...

This study was conducted to determine the effects of various doses and particle sizes (micro or nano) of dietary zinc and zinc oxide on growth performance, serum enzyme activities, carcass characteristics, and zinc requirements in Japanese quails. A total of 576 day-old Japanese quails (both sexes) were housed in 36 deep litter floor pens. Birds received a basal corn–soybean meal diet that was ...

This study focused on the effects of zinc oxide nanoparticles (nano-ZnO) on spatial learning and memory and synaptic plasticity in the hippocampus of young rats, and tried to interpret the underlying mechanism. Rats were randomly divided into four groups. Nano-ZnO and phosphate-buffered saline were administered in 4-week-old rats for 8 weeks. Subsequently, performance in Morris water maze (MWM)...

in the present work, we report the synthesis of binary nano metal oxides such as zinc /copper oxide via novel dry synthetic methods such as thermal decomposition of oxalate precursor. the synthesis route involves facile solid-phase mechanochemical activation of a physical mixture of simple copper/zinc salts and oxalic acid, followed by calcination of the as-ground oxalate precursors at 450◦c. x...

unsubstituted phthalocyanines of co, fe and mn supported on zinc oxide nanoparticles were prepared and were well characterized with x-ray diffraction (xrd) and scanning electron microscopy (sem). the oxidation of alcohols with tert-butylhydroperoxide (tbhp), in the presence of metallophthalocyanines (mpc) supported on zinc oxide nanoparticles was investigated. these mpc/zno nanocomposites were ...

Improving human health is the considered major concern in area of medical and agricultural sciences. It achieved by providing good supplements with balanced diet to people forms cost effective safe nano-biofortified or nano-bioengineered vegetable crop plants fight against malnutrition other various diseases. And these nano-based methodologies are involved use nanoparticles essential nutrients ...

introduction: today nano-medicine tries to produce new drugs to reduce the dosage and side effects of their conventional forms. according to the interaction between zinc and opioidergic system activity, this study has investigated the effect of new kind of zinc supplement, nano zinc oxide (nzno), in compared to its conventional form (czno), in presence and absence of opioidergic system activity...
