Extended Abstract Introduction and Objective: In recent years, studies have focused on the use of new compounds that can be synthesized inside the plant and increase the photosynthetic efficiency of the plant. Some of these compounds include micronutrients and alcohols. Alcohols such as methanol as a carbon source will increase photosynthetic efficiency and improve plant growth parameters. Tit...
Strawberry (Fragaria × ananassa Dutch) is a widely grown fruit crop in the world due to its high aroma, taste, and nutritional value. In this study, the effect of foliar application of titanium dioxide nanoparticles on phytochemical modifications of strawberry cv. Sabrina under deficit fertigation conditions was investigated. The interaction effect of titanium dioxide nanoparticles (0, 6 and 12...
Nanoparticles of titanium increase cell growth by improvement of photosynthetic and nitrogen metabolism and therefore, caused an increasing in weight of the plant. This re-search was conducted to evaluate seed yield and biochemical traits of bread wheat affected by different levels of titanium dioxide Nanoparticles in Ahvaz region, Khuzestan province, located at southwestern Iran by factorial e...
Extended Abstract Introduction: Drought stress, as abiotic and multidimensional stress, has severe effects on plant growth. One of the new approaches in the management of drought stress is the use of nanoparticles. Nanoparticles infilterate the seeds and increase nutrient and water uptake and ultimately, improve germination. The present research was conducted to evaluate the effects of titaniu...
backgrounds and objectives: photocatalyst titanium dioxide nanoparticles can oxidize organic and inorganic compounds of microorganisms in aqueous solutions after exposure to uv light. in the present study, the inhibitory effect of titanium dioxide and its photocatalyst type on aspergillus flavus , escherichia coli and staphylococcus aureus is investigated. materials and methods: toxicogenic s...
The potential health effects of inhaled engineered nanoparticles are almost unknown. To avoid and replace toxicity studies with animals, a triple cell co-culture system composed of epithelial cells, macrophages and dendritic cells was established, which simulates the most important barrier functions of the epithelial airway. Using this model, the toxic potential of titanium dioxide was assessed...
Nanoparticles synthesised by fungi have various applications and is much effective than the nanoparticles synthesised by other means. The present study is aimed to determine the antimicrobial potential of Titanium dioxide nanoparticles synthesised from the fungus, Aspergillus niger. The synthesised nanoparticles were characterised using UV spectrophotometer, SEM, and XRD. The antibacterial acti...
Dentistry and orthopedics are undergoing a revolution in order to provide more reliable, comfortable and long-lasting implants to patients. Titanium (Ti) and titanium alloys have been used in dental implants and total hip arthroplasty due to their excellent biocompatibility. However, Ti-based implants in human body suffer surface degradation (corrosion and wear) resulting in the release of meta...
A simple single-stage approach, based on the hydrothermal technique, has been introduced to synthesize reduced graphene oxide/titanium dioxide nanocomposites. The titanium dioxide nanoparticles are formed at the same time as the graphene oxide is reduced to graphene. The triethanolamine used in the process has two roles. It acts as a reducing agent for the graphene oxide as well as a capping ag...
Titanium dioxide and copper oxide nanoparticles are more and more widely used because of their catalytic properties, of their light absorbing properties (titanium dioxide) or of their biocidal properties (copper oxide), increasing the risk of adverse health effects. In this frame, the responses of mouse macrophages were studied. Both proteomic and targeted analyses were performed to investigate...
