In this paper, the authors define heat transfer and its applications: heat transfer by conduction principles of heat flow in fluids, heat transfer to fluids without phase change heat transfer in fluids with heat change radiation heat transfer heat-exchange equipment evaporation.Abstract:
Part 1 Introduction: definitions and principles. Part 2 Fluid mechanics: fluid statics and its applications fluid flow phenomena basic equations of fluid flow flow of incompressible fluids in conduits and thin layers flow of compressible fluids flow past immersed bodies transportation and metering of fluids agitation and mixing of liquids. Part 3 Heat transfer and its applications: heat transfer by conduction principles of heat flow in fluids heat transfer to fluids without phase change heat transfer to fluids with heat change radiation heat transfer heat-exchange equipment evaporation. Part 4 Mass transfer and its applications: equilibrium stage operations distillation introduction to multicomponent distillation leaching and extraction principles of diffusion and mass transfer between phases gas absorption humidification operations drying of solids adsorption membrane separation processes crystallization. Part 5 Operations involving particulate solids properties, handling and mixing of particulate solids size reduction mechanical separations.read more

A critical review on solvent extraction of rare earths from aqueous solutions
TL;DR: In this article, the chemistry of different solvent extractants and typical configurations for rare earth separations are reviewed. But the choice of extractants is influenced by both cost considerations and requirements of technical performance.
Journal ArticleDOI
Cerium and yttrium oxide nanoparticles are neuroprotective.
TL;DR: It is shown here that nanoparticles composed of cerium oxide or yttrium oxide protect nerve cells from oxidative stress and that the neuroprotection is independent of particle size.
