Nanocrystalline ZnO particles were prepared from ethanolic solutions of zinc acetate by forced hydrolysis, at a low temperature. The fresh prepared ZnO nanoparticles were coated with gentamicin. The nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and thermal analysis (TG-DSC). The electronic (UV-Vis), infrared (FTIR) and photoluminescence (PL)...

Nanoparticles of zinc oxide (ZnO) were prepared by the precipitation method from zinc sulphate (ZnSO4.7H2O) and sodium bicarbonate (NaHCO3). Organization, stabilization of the ZnO nanoparticles from further growth and partially inhibiting the photodegradation was achieved by capping with poly vinyl pyrrolidone (PVP). Fourier transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRD)...

A method for the production of antibacterial ZnO nanoparticles has been developed. The technique combines passing an electric current with simultaneous application of ultrasonic waves. By using high-power ultrasound a cavitation zone is created between two zinc electrodes. This leads to the possibility to create a spatial electrical discharge in water. Creation of such discharge leads to the de...

Pd nanoparticles were well dispersed on a new triptycene-based microporous polymer support by the gas bubbling-assisted membrane reduction (GBMR) method. The stability of Pd nanoparticles is improved by the porous support, and the materials show excellent performance for CO oxidation.

Stearate@Cu/ZnO nanocomposite particles with molar ratios of ZnO : Cu = 2 and 5 are synthesized by reduction of the metal–organic Cu precursor [Cu{(OCH(CH3)CH2N(CH3)2)}2] in the presence of stearate@ZnO nanoparticles. In the case of ZnO : Cu = 5, high-angle annular dark field-scanning transmission electron microscopy (HAADF-STEM) combined with electronenergy-loss-spectroscopy (EELS) as well as ...

Considering the photocatalytic performance of CDs, ZnO, and unique porous nanostructure stability ZIF-8, we prepared ZnCDs/ZnO@ZIF-8 zeolite composites. The resultant material represented an enhanced ability for photodegradation TC compared with that ZnCDs ZnO. degradation efficiency reached over 85%. catalytic activity composites was maintained after four cycles. experimental result indicated ...

C-dopedZnOhierarchically porous nanoarchitectures were synthesized in situ on indium tin oxide (ITO) through a counter strategy. The PECperformance of the C-doped ZnOnanoarchitectures in the splitting of water without sacrificial reagents was systematically evaluated for the first time. In comparison to other ZnO-based photoanodes in the literature, C-doped ZnO nanoarchitectures exhibit a strik...

We propose a method for the synthesis of a colloidal ZnO solution with poly(N-vinylpyrrolidone) (PVP) as stabilizer. Stable colloidal solutions with good luminescence properties are obtained by using PVP as stabilizer in the synthesis of ZnO nanoparticles by a sol-gel method assisted by ultrasound. Nanoparticles with sizes of 30-40 nm in a PVP matrix are produced as a solid product. The colloid...

There has been a significant and growing concern over nosocomial medical device infections. Previous studies have demonstrated that embedding nanoparticles alone (specifically, zinc oxide [ZnO]) in conventional polymers (eg, polyvinyl chloride [PVC]) can decrease bacteria growth and may have the potential to prevent or disrupt bacterial processes that lead to infection. However, little to no st...
