Liquid desiccants such as glycols are used in dehydration process, among which Triethylene Glycol (TEG) is considered as a common choice. The addition of nanoparticles to TEG as the base fluid is one of the prevalent method to improve thermal properties of TEG. In this study, an experimental investigation was performed on thermal conductivity of TEG-based nanofluids with 20 and 40 nm diameter c...

Nano structured materials have wide range of applications due to their interesting size-dependent chemical and physical properties compared to particles of size in the range of micrometer. Copper oxide nano materials are of interest on account of their potential uses in many technological fields. In this study  CuO nanoparticles were synthesized via simple sol gel method using basic CuSO4<...

Two stable nanofluids comprising of mixed valent copper(I,II) oxide clusters (<1 nm) suspended in 1-butyl-3-methylimidazolium acetate, [C(4)mim][OAc], and copper(II) oxide nanoparticles (<50 nm) suspended in trioctyl(dodecyl)phosphonium acetate, [P(8 8 8 12)][OAc], were synthesised in a facile one-pot reaction from solutions of copper(II) acetate hydrate in the corresponding ionic liquids. Form...

background: antibiotic resistant bacteria can be considered as a main problem in infection management. zinc oxide nanoparticles (zno nps), individually or in combination with antibiotics, can be considered as good candidates for struggling against drug resistant bacteria. methods: in this study, zinc oxide nanoparticles were synthesized using sol-gel method in low temperature as a cost effectiv...

Glasses containing metallic nanoparticles are promising materials for technological applications in optics and photonics. Although several methods are available to generate nanoparticles in glass, only femtosecond lasers allow controlling it three-dimensionally. In this direction, the present work investigates the generation of copper nanoparticles on the surface and in the bulk of a borosilica...

The study included 70 Surface swabs collected from patients in different ages of both genders suffering burns infections. All the specimens were diagnosed by subculturing differential and selective media, microscopically following biochemical tests to confirm identifications. Antibiotic susceptibility test was done all bacterial isolates.The identification clinical isolates showed that 16(22.9%...

Wear is the progressive loss of the material from the operating surface of machine due to relative motion between surfaces. The successful design of machine elements depends upon essentially on the understanding tribological principles like wear and friction. The lubricating oils are the blood of the machine’s operation, and the service life and economic effectiveness of the machine are relativ...

Increasing use of engineered nanoparticles (NPs) is likely to result in release of these particles to the aquatic environment where the NPs may eventually accumulate in sediment. However, little is known about the potential ecotoxicity of sediment-associated engineered NPs. We here consider the case of metal oxide NPs using CuO to understand if the effects of NPs differ from micron-sized partic...

This study aims to provide an updated survey of the main synthesis methods of copper oxide (CuO) nanoparticles in order to obtain tailored nanosystems for various biomedical applications. The synthesis approach significantly impacts the properties of such nanoparticles and these properties in turn have a significant impact on their biomedical applications. Although not widely investigated as an...
