Nanoparticle-Filled Liquid Fuels for Efficient Energy Conversion

Nanofuels exhibit great potential for increasing the combustion efficiency of liquid-fueled engines, because of their enhanced thermal and mass transport properties, their higher volumetric heating value relative to pure liquid fuels, and the extremely high surface-area-to-volume ratio of the energetic nanoparticles. Nanofuels, or nanoparticle-filled liquid fuels, are one type of nanofluid, i.e., a nanoscale colloidal […]

Solar-Powered Adsorption Cooling

Solar-powered cooling is an attractive concept in that one utilizes solar energy, which is the largest component of a building’s cooling load, to drive a heat-activated air-conditioning system, thus reducing or eliminating the need for conventional, electric-powered air conditioning. Most solar-powered air-conditioning systems to date have been based on well-known absorption refrigeration, which requires difficult-to-handle […]
