Transmitting data from space to earth with laser filaments

Could light be used to transmit information between satellites and Earth? Atmospheric water vapor scatters and absorbs light energy, but overcome that obstacle, and light will carry far more information and move it faster ...

Chemists create the brightest-ever fluorescent materials

By formulating positively charged fluorescent dyes into a new class of materials called small-molecule ionic isolation lattices (SMILES), a compound's brilliant glow can be seamlessly transferred to a solid, crystalline state, ...

Biphilic surfaces reduce defrosting times in heat exchangers

Ice formation and accumulation are challenging concerns for several industrial applications including heating ventilation air conditioning and refrigeration (HVAC&R) systems, aircraft, energy transmission, and transportation ...

Graphene: It is all about the toppings

Graphene consists of a single layer of carbon atoms. Exceptional electronic, thermal, mechanical, and optical properties have made graphene one of the most studied materials at the moment. For many applications in electronics ...

Mid-infrared flare detected in a nearby active galaxy

Chinese astronomers have reported the discovery of a mid-infrared flare in a nearby star-forming galaxy known as MCG-02-04-026. The finding is detailed in a paper published June 22 on arXiv.org, in which the authors try to ...

Geometry of intricately fabricated glass makes light trap itself

Laser light traveling through ornately microfabricated glass has been shown to interact with itself to form self-sustaining wave patterns called solitons. The intricate design fabricated in the glass is a type of "photonic ...
