Electric transport measurements across single grain boundaries in YBa2Cu3O7 films are summarized. These experiments demonstrate that YBa2Cu3O7 grain boundaries behave like SNS-type Josephson junctions. The implications of this weak link behavior for the critical currents of polycrystalline...

Presently out of the total energy consumption, a large share of energy is being used by refrigeration and air conditioning equipments. The present study is based on literature review on the refrigeration systems, currently used refrigerant–absorbent pairs and also on different sources of...

The impact of global warming and an increase in the indoor cooling equipments using energy sources other than conventional energy have become very attractive because they can reduce consumption of fossil fuels as well as harmful emissions in to the environment. The solar energy is one of the...
