A novel biosensor was developed by immobilizing hemoglobin (Hb) on a glassy carbon electrode (GCE) modified with a composite of ZnO nano-rods and carbon nanofiber (CNF), a strong reducer, hydrazine, was firstly used to evaluate the electrochemical behavior of Hb on Hb/ZnO/CNF/GCE. UV-vis and circular dichroism (CD) spectra indicated the conformational structure of Hb interaction with ZnO/CNF wa...

Sn–Ag–Cu composite solders reinforced with nano-sized, nonreacting, noncoarsening 1 wt% TiO2 particles were prepared by mechanically dispersing TiO2 nano-particles into Sn–Ag–Cu solder powder and the interfacial morphology of the solder and flexible BGA substrates were characterized metallographically. At their interfaces, different types of scallop-shaped intermetallic compound layers such as ...

OBJECTIVE Nano components are today's new wonder material. However, the safety or toxicity of these components in humans is not yet clear. In a previous study we indicated that nano ZnO (nZnO) has a stronger anxiolytic effect compared to the conventional ZnO (cZnO). The present study was designed to evaluate the intraperitoneal administration of an opioidergic receptor agonist and antagonist of...

Minimally processed pomegranate rapidly loses its overall quality because of high water loss and microbial contamination. Nano-ZnO in combination with carboxymethyl cellulose (CMC) coating was used on pomegranate arils. Arils were dipped for 4min in distilled water (control), 0.1 or 0.2% (w/v) nano-ZnO suspension and then ZnO treated arils were coated with 0.5% (w/v) CMC and stored for 12days a...

Composite coatings of Co–Ni–Al O were studied by electrolytic codeposition of Co–Ni alloys and Al O from a sulfamate 2 3 2 3 electrolyte containing Al O particles. The influence of plating parameters on the content of the co-deposited Al O particles in 2 3 2 3 Co–Ni alloys was investigated. The maximum value of co-deposited Al O can be achieved at a particle content of 80 g l in y1 2 3 bath, a ...

AbstractSputtered MoS2 coatings have been mostly used as a solid lubricant. In this investigation, MoSx/Ni composite coatings with Ni contents varying from 0 to 22 % were deposited onto steel substrate using a DC magnetron sputter process. The MoS2/Ni ratio in the coatings was controlled by sputtering the composite targets. The composition, microstructure, and mechanical properties of the...

The influence of different application methods on UV protective properties of white and dyed cotton functionalized with ZnO nanoparticles (nano-ZnO) was investigated. The methods differ in application procedure, time of treatment and auxiliaries used in the treating bath. The ultraviolet protection factor (UPF) was determined for untreated and functionalized samples. The presence of nano-ZnO on...

Nano ZnO/ montmorillonite composite were prepared by sol gel method under ultrasonic irradiation from directly mixing montmorillonite nano clay into Zinc gel. The Zn(CH3COO)2.2H2O and montmorillonite nano clay was used as precursor. The zinc acetate was dissolved in DI water and, NH3 (aq) solution was dropped into the zinc solution until pH 9 consequently the zinc gel was produced. The montmori...

The aim of this study was to compare the effect of dietary supplementation with low dose of porous and nano zinc oxide (ZnO) on weaning piglets, and to evaluate the possibility of using them as an alternative to high dose of regular ZnO. Piglets were randomly allocated into four treatment groups fed with four diets: (1) basal diet (NC), (2) NC+ 3000 mg/kg ZnO (PC), (3) NC + 500 mg/kg porous ZnO...
