Abstract: Nanofluids, in which nano-sized particles (typically less than 100 nanometers) suspended in liquids, have emerged as a potential candidate for the design of heat transfer fluids. The main goal of nanofluids is to achieve the highest possible thermal properties at the smallest possible concentrations by uniform dispersion and stable suspension of nanoparticles in host fluids. This paper also includes diverse applications of nanofluids. Along with the cooling applications, there are tribological and medical applications for nanofluids. Nanofluids could be utilized for a wide variety of applications in day today life. The problem of laminar fluid flow which results from an inclined stretching flat surface in nanofluid has been investigated numerically in this paper. The model used here for the considers the effects of Brownian motion and thermophoresis. A similarity solution is presented which depends on the Prandtl number Pr, Lewis number Le, Brownian number Nb and thermophoresis number

Abstract: Recently, attention has been given to an innovative class of biochar derived from solar pyrolysis because of its potential to provide an efficient, environmentally acceptable, and cost-effective method for the exploitation of a totally renewable energy source to obtain pyrolyzation, such as solar irradiation. A simple and innovative prototype for biomass pyrolysis is presented, together with some experimental results. The setup allows only the thermal solar energy provided by a system of reflecting mirrors (Linear Mirror II) to heat a selected and local agro-waste biomass. Characterization and effects of biomass which was thermally treated using the Linear Mirror II to perform pyrolysis only through solar energy and without any help from other thermal auxiliary sources is discussed too.
