Transparent Polymer Coatings for Energy-Efficient Daytime Window Cooling

Flexible transparent graphene/polymer multilayers for efficient electromagnetic field absorption

Thanks to its high electrical conductivity, a graphene plane presents a good shielding efficiency against GHz electromagnetic radiations. Several graphene planes separated by thin polymer spacers add their conductivities arithmetically, because each of them conserves the intrinsic properties of isolated graphene. Maximum absorption of radiations for frequency around 30 GHz is achieved with six ...

The Optical Properties of Black Coatings and Their Estimated Cooling Effect and Cooling Energy Savings Potential

The optical properties of coatings pigmented with different black colorants were systematically investigated and their surface temperatures and cooling energy savings were estimated. The black coatings pigmented with chromite iron nickel black and manganese ferrite black spinel colorants are not cool enough to be energy efficient cool black coatings. The cool black coatings pigmented with NIR-t...

Model Predictive Control for Energy Efficient Cooling and Dehumidification

Energy has become a primary concern in countries worldwide, and is a focus of debates on national security, climate change, global economy, and the developing world. With more people in developing countries adopting the lifestyle of western countries as rapidly as possible, limited only by economic means, a tremendous increase in world’s energy consumption in the next few decades seems difficul...

Energy Efficient Gas Cooling for Two -Stage Ammonia Refrigerating Plants

An Energy Efficient Instruction Window for Scalable Processor Architecture

Modern microprocessors achieve high application performance at the acceptable level of power dissipation. In terms of power to performance trade-off, the instruction window is particularly important. This is because enlarging the window size achieves high performance but naive scaling of the conventional instruction window can severely increase the complexity and power consumption. In this pape...
