In recent years, tremendous research efforts have been made towards developing graphene (GR)-based nanocomposites for photocatalytic applications. In this work, surface-coarsened TiO2 nanobelts (SC-TNBs) closely enwrapped with monodispersed Ag nanoparticles (NPs) and GR nanosheets (i.e. Ag/GR/SC-TNBs) were fabricated using a facile self-assembly strategy followed by photoreduction. It was found...

Understanding the salinity stress mechanisms is essential for crop improvement and sustainable agriculture. Salinity prepotent abiotic compared with other stresses that decrease growth development, reducing production creating food security-related threats. Therefore, input of metal oxide nanoparticles (NPs) such as zinc (ZnO-NPs) can improve salt tolerance in plants, especially early stage gro...

The glucocorticoid steroid hormone cortisol is released by the adrenal glands in response to stress and serves as a messenger in circadian rhythms. Transcriptional responses to this hormonal signal are mediated by the glucocorticoid receptor (GR). We determined GR binding throughout the human genome by using chromatin immunoprecipitation followed by next-generation DNA sequencing, and measured ...

The Moldavian dragonhead (Dracocephalum moldavica L., Lamiaceae) is an annual medicinal plant with beneficial nutritional sources that plays important roles in human and animal feed. Nanoparticles and cold atmospheric plasma increase biochemical compounds in plants. In this study, the effects of copper nanoparticles and cold atmospheric plasma on biochemical indices of the medicinal plant Draco...

background: therapeutic and diagnosis properties of radioactive gold nanoparticle (198-aunps) cause them to be suitable for detection and treatment of tumors. objective: electrical and optical properties of peg-198aunps were examined in this paper. polyethylene glycol (peg)-198 aunps can be used for treatment and diagnosis of small intestine tumors. methods: wireless fluorescence capsule endosc...

The present study prepares alkali lignin (AL) via acidification of black liquor, obtained from a pulp and paper factory. The average molecular weight of AL (equal to 2,530 g/mol) has been determined with gel permeation chromatography. AL has been modified by ethylene glycol, while lignin nanoparticles (LN) has been prepared through acid precipitation technology, their size being assessed by mea...

Objective: Oxidative stress is a leading factor in the development of silver nanoparticle-induced toxicity. This study evaluated the effects of oral prescription of different doses of silver nanoparticles and propolis on lipid peroxidation in male Wistar rats. Materials and Methods: The male wistar rats were randomly divided into four groups. Control group and three different treatment groups ...

In this study chemical method of dissolution-Precipitation was applied to produce amorphous silica nanoparticles from rice straw ash (RSA), the waste material of rice cultivation. The morphology, particle size, structure and area of specific surface of synthesized amorphous silica nanoparticles were evaluated using transmission electron microscopy (TEM), X-ray diffraction analysis (XRD) and BET...
