House windows that double as solar panels?

Quantum dots are embedded plastic and capture sunlight to improve solar panel efficiency. LANL illustration.

A house window that doubles as a solar panel could be on the horizon, thanks to recent quantum-dot work. Scientists have demonstrated that superior light-emitting properties of quantum dots can be applied in solar energy by helping more efficiently harvest sunlight.

"The key accomplishment is the demonstration of large-area luminescent solar concentrators that use a new generation of specially engineered quantum dots," said lead researcher Victor Klimov." (Full Story)

The $1.5m golden nugget: World’s largest single crystal of gold discovered

Researchers at Los Alamos National Laboratory have determined that this is the world's largest single crystal of gold. LANL photo.

Government experts have confirmed the world’s largest single crystal of gold. Researchers at Los Alamos National Laboratory used a neutron scanner to effectively look inside the 217.78-gram piece of gold.

The team at Los Alamos National Laboratory used the Lujan Neutron Scattering Center to look deep inside the mineral using neutron diffractometry. Neutrons, different from other probes such as X-rays and electrons, are able to penetrate many centimeters deep into most materials. (Full Story)



World’s largest gold crystal found

It's the size of a golf ball, but a lot more valuable: Scientists at Los Alamos National Laboratory's Lujan Neutron Scattering Center have verified that a heavy piece of gold, found years ago in Venezuela, is, in fact, a single crystal of the valuable element — and it's worth an estimated $1.5 million.

The lump of gold, which weighs 217.78 grams (about 7.7 ounces), was brought to Los Alamos to confirm whether it was a single crystal of gold, or a more common multiple-crystal structure. (Full Story)
