Heat pumps decarbonize the building sector, yet their high capital costs relative to gas boilers remain a barrier to widespread adoption. This comment emphasizes that optimal heat pump system design ...

Capillary pumping is an attractive means of liquid actuation because it is a passive mechanism, i.e., it does not rely on an external energy supply during operation. The capillary flow rate generally ...

Insulin pumps provide a precisely controlled rate of insulin delivery to diabetic patients who would normally need multiple daily injections to regulate blood glucose levels. Insulin pumps improve ...

A British-Swedish research team has reviewed all models for designing and simulating solar-powered heat pumps systems of various complexities. Based on this work, the scientists proposed a new method ...
