“…The oxides of transition metals are an important class of semiconductors, which have applications in magnetic storage media, solar energy transformation, electronics, gas sensors and catalysis (Ramgir et al 2013;Jani et al 2013;Shalana et al 2013;Montferrand et al 2013;Ahmadi et al 2011). Although various physical and chemical methods have been extensively used to produce nanocrystalline copper oxide such as microemulsion method (Nassar and Husein 2007), arc-submerged nanoparticle synthesis system (Kao et al 2007), flame-based aerosol methods (Chiang et al 2012), sonochemical (Vijayakumar et al 2001), hydrothermal (Zhang et al 2006) and solid-state techniques (Wang et al 2004), the stability and the use of toxic chemicals are subjects of paramount concern. The use of toxic chemicals on the surface of nanoparticles and non-polar solvents in the synthesis procedure limits their applications in clinical fields.…”

Recently, biosynthesis of nanoparticles has attracted scientists' attention because of the necessity to develop new clean, cost-effective and efficient synthesis techniques. In particular, metal oxide nanoparticles are receiving increasing attention in a large variety of applications. However, up to now, the reports on the biopreparation and characterization of nanocrystalline copper oxide are relatively few compared to some other metal oxides. In this paper, we report for the first time the use of brown alga (Bifurcaria bifurcata) in the biosynthesis of copper oxide nanoparticles of dimensions 5-45 nm. The synthesized nanomaterial is characterized by UV-visible absorption spectroscopy and Fourier transform infrared spectrum analysis. X-ray diffraction confirms the formation and the crystalline nature of copper oxide nanomaterial. Further, these nanoparticles were found to exhibit high antibacterial activity against two different strains of bacteria Enterobacter aerogenes (Gram negative) and Staphylococcus aureus (Gram positive).

“…Many researches have elucidated that nanofluid has extremely good performance in heat conduction and heat convection. There would be breakthrough development of nanofluid towards the improvement of heat transfer performance of traditional working fluid [5][6][7][8][9][10][11][12][13][14][15][16]. Nevertheless, the related references about the application of nanofluid to heat pipe were not published until 2004.…”

“…Possible mechanisms are catalytic processes at the nanoparticle surface as well as increased evaporation rates due to radiation absorption by the particles [83][84][85][86][87][88][89][90][91][92][93][94]. Kao et al as well as Sarkar and Hirani suggested the addition of nanoparticles to brake fluids to improve thermal transport of dissipated braking energy and increase the boiling point to avoid vapor lock [95,96]. Another part of the car that could improve by nanofluids is the damping system: Magnetorheological fluids allows for continuous adjustment of dampers by electromagnets.…”

h i g h l i g h t s Thermophysical properties bring nanofluids into various engineering applications. Quantity of variable parameters hinder comprehensive equations, e.g. for viscosity. Coordinated research can help to overcome debates about thermophysical properties. Missing experience for nanofluids in large scale plants. Lack of studies about high pressure/temperature applications and long term behavior. a b s t r a c tIn the roughly two decades from the first publication until today, nanofluids have found their way into various research fields. To-date published documents range from basic research to high-tech applications. This contribution aims at outlining current fields of research regarding nanofluid research. These range from fundamental property data studies presented in the first section to a listing of numerous applications of different fields of engineering. It is shown that nanofluid science pushes increasingly into the scientific world providing plenty of new questions and challenges.
