Scientists announce the quest for high-index materials

An antenna is a device capable of effectively transmitting, picking up, and redirecting electromagnetic radiation. Typically, antennas are macroscopic devices operating in the radio and microwave range. However, there are ...

NASA study finds solar storms could spark soils at moon's poles

Powerful solar storms can charge up the soil in frigid, permanently shadowed regions near the lunar poles, and may possibly produce "sparks" that could vaporize and melt the soil, perhaps as much as meteoroid impacts, according ...

Modeling the fluorescence enhancing capabilities of materials

The capacity of various noble metals and dielectrics to enhance fluorescence has been compared by A*STAR researchers, with a view for more sensitive technologies to create new applications in biology and medicine.

Engineers discover a high-speed nano-avalanche

Charles McLaren, a doctoral student in materials science and engineering at Lehigh University, arrived last fall for his semester of research at the University of Marburg in Germany with his language skills significantly ...

'Ideal' energy storage material for electric vehicles developed

The energy-storage goal of a polymer dielectric material with high energy density, high power density and excellent charge-discharge efficiency for electric and hybrid vehicle use has been achieved by a team of Penn State ...

Artificial muscle for soft robotics: Low voltage, high hopes

Soft robots do a lot of things well but they're not exactly known for their speed. The artificial muscles that move soft robots, called actuators, tend to rely on hydraulics or pneumatics, which are slow to respond and difficult ...
