Background: Based on the increase in antibiotic-resistant pathogens, it is necessary to have various effective compounds, so as to prevent the proliferation of these pathogens. For this purpose, nano-materials such as bismuth oxide nanoparticles can be used.Objectives: The aim of this study was to produce bismuth oxide nanoparticles by Bacillus lichenifor...
Limited control over charge recombination between photogenerated charge carriers largely hinders the progress in photocatalysis. Here, we introduce metal nanoparticles (Cr, Ag) to the surface of MoS2 nanosheets by simple synthetic means creating a hybrid metal-MoS2 nanosheet system with well-defined metal/semiconductor interfaces. We demonstrate that this hybrid nanosheet structure is capable o...
In this research, the inhibitory effects of silver nanoparticles and zinc oxide nanoparticles, in vitro, on disease stone fruits bacterial canker caused by Pseudomonas syrigae pv. Syringae and disease bacterial blight caused by Xanthomonas arboricola pv. juglandis, were studied. Different concentrations of nanoparticles were prepared on Mueller Hinton agar medium in two different ways in a com...
Copper oxide nanoparticles (CuO-NPs) synthesized by an implicitly environmentally benign process using Acanthospermum hispidum L. aqueous plant extract as an effective bio-oxidizing/bio-reducing agent. Phytochemical screening of the fresh aqueous leaves extract showed the presence of coumarins, tannins, saponins, phenols, flavonoids, sterols and volatile oils. Fourier transform infrared spectro...
Background and Aims: Iron oxide nanoparticles are among the most effective tools which can replace current medical techniques for diagnosis and treatment of various diseases. Hepatitis C infection is one of the main health problems in the world, affecting around 3% of the world's population. This infection can develop into liver cirrhosis and liver cancer over the time in 80% of patients. In t...
The splitting of water into hydrogen and oxygen molecules using sunlight is an attractive method for solar energy storage. Until now, photoelectrochemical hydrogen evolution is mostly studied in acidic solutions, in which the hydrogen evolution is more facile than in alkaline solutions. Herein, we report photoelectrochemical hydrogen production in alkaline solutions, which are more favorable th...
Ammonia (NH3) is produced from atmospheric nitrogen and hydrogen from a hydrocarbon source. Natural gas is the most commonly used hydrocarbon feedstock for new plants; other feedstocks that have been used include naphtha, oil, and gasified coal. Natural gas is favored over the other feedstocks from an environmental perspective. Ammonia production from natural gas includes the following processe...
The study investigates the effect of aluminium oxide nanoparticles as an additive to Madhuca Indica (mahua) methyl ester blends on performance, emission analysis of a single-cylinder direct injection diesel engine operated at a constant speed at different operating conditions. The test fuels are indicated as B10A0.2, B10A0.4, B20A0.2, B20A0.4 and diesel respectively. The results indica...
The antimicrobial effect of metal nanoparticles such as zinc oxide and silver nanoparticles has been taken into great consideration separately during recent years. The useful application of these nanoparticles in the areas of medicine, biotechnology, and professional prevention of microbes motivated us. The aim of this study was to evaluate antibacterial activity properties of silver doped zinc...
in this report, magnetic iron oxide nanoparticles were synthesized via coprecipitation of fe2+ and fe3+ with ammonium hydroxide, and the surface of synthesized nanoparticles was organically functionalized by commercially available amine coupling agent namely, 3-aminopropyl trimethoxysilane (apts) by using well-known sol–gel method. further reaction of the synthesized fe3o4@apts core-shell magne...
