New technology can help vessels glide quickly over water in less time and with fewer emissions than their diesel counterparts ...

A material that emits less energy than it absorbs has the potential to save some of the sunlight wasted by solar collectors.

It is possible to make a material emit more radiation than it absorbs, violating the laws of physics in a way that could make ...

Town officials call say a power surge an "Act of God." But lost home appliances and municipal financial documents suggest ...

A new material developed at Penn State defies a fundamental law of physics, opening doors to highly efficient solar cells.

Why do some changes in nature unfold gradually, while others occur in the blink of an eye? Rust forming on metal is a slow, ...

You may think you know static electricity, but its true nature has long eluded scientists. We’ve now made a huge leap towards ...

Wind energy conversion systems (WECS) nowadays offer an extremely wide range of topologies, including various different types of electrical generators and power converters. Wind energy is also an ...

A considerable part of the energy dissipation in CMOS buffers is due to short-circuit currents. In this paper, an accurate, analytical and compact model for this part of energy, i.e. the short-circuit ...

Fluorescent dyes rhodamine 6G (R6G) and rhodamine B (RhB) were simultaneously introduced to mesoporous MCM-41, SBA-15, and MCM-48 molecular sieves. XRD, N2 adsorption−desorption isotherm, atomic ...
