BACKGROUND Diarrhea in piglets is one of the main causes of animal death after weaning; zinc oxide (ZnO) has been used in high doses for the control of this sickness. The aim of this study was to determine the physicochemical properties of ZnO nanoparticles synthesized and immobilized on a chitosan/alginate (CH/SA) complex and investigate the antimicrobial activity and in vitro release profile ...

A stepwise surface functionalization methodology was applied to nanostructured ZnO films grown by metal organic chemical vapor deposition (MOCVD) having three different surface morphologies (i.e., nanorod layers (ZnO films-N), rough surface films (ZnO films-R), and planar surface films (ZnO films-P). The films were grown on glass substrates and on the sensing area of a quartz crystal microbalan...

here, in situ synthesis of nano zinc oxide, along with aminolysis of polyester fabric, has simultaneously been carried out by using triethanol amine (tea) and zinc acetate. the zno nano particles (nps) were formed and stabilized on the fabric surface by amine compound at 130 °c for 1 h. the synthesis of nano zno particles on the polyester fabric were confirmed by x-ray diffraction (xrd) pattern...

Antimicrobial active films based on poly (lactic acid) (PLA) were prepared with nano-silver (nano-Ag) and nano-zinc oxide (nano-ZnO) using a solvent volatilizing method. The films were characterized for mechanical, structural, thermal, physical and antimicrobial properties. Scanning electron microscopy (SEM) images characterized the fracture morphology of the films with different contents of na...

ZnO and Mn-ZnO nano powders were prepared by the sol-gel auto combustion method. The products were characterized by X-ray diffraction (XRD), energy dispersive analysis of X-ray (EDX) and scanning electron microscopy (SEM). Structural and morphological properties of nano particles were investigated and the average crystalline size of ZnO and Mn-doped ZnO was obtained 44 and 51 nm, respectively. ...

Zinc oxide (ZnO) is one of the light in ultraviolet (UV) region. In addition, ZnO nano attracting increasing research interest as buildin optoelectronic applications. We have succeede vertically-aligned ZnO nanostructures by laser inter which is catalyst-free and non-contact techniq vertically-aligned ZnO nanowall arrays were two-beam interference. The maximum height and a the ZnO nanowalls wer...

statement of the problem: during the orthodontic treatment, microbial plaques may accumulate around the brackets and cause caries, especially in high-risk patients. finding ways to eliminate this microbial plaque seems to be essential. purpose: the aim of this study was to compare the antibacterial effects of nano copper oxide (cuo) and nano zinc oxide (zno) coated brackets against streptococcu...

abstract increase in the use of nano zinc oxide in medicine, manufacturing cosmetic products and research, have raised the questions about their toxicity. zinc has direct role in growth, maturation and ovulation through influence on production of estradiol and progesterone. in this study the effects of nano zinc oxide on oogenesis of adult nmri mouse strain have been investigated. the adult fem...

ZnO nanowires are a promising nanomaterial for applications in the fields of photocatalysis, nano-optoelectronics, and reinforced composite materials. However, the challenge of producing large-scale ZnO nanowires has stunted the development and practical utilization of ZnO nanowires. In this study, a modified carbothermal reduction method for preparing large-scale ZnO nanowires in less than 5 m...
