Platinum-gold mix becomes world's most durable metal alloy

Michael Irving August 16, 2018

Sandia engineers have developed the most durable metal alloy ever created. Made up of a combination of platinum and gold, the new material is 100 times more wear-resistant than high-strength steel, and the first metal alloy to join the same class as diamond. It also produces its own lubricant.

Sandia Labs completes nuclear triathlon to test spent fuel safety

David Szondy March 13, 2018

To ensure that moving spent radioactive fuel is being carried out with the minimum of risks, Sandia National Laboratories recently completed a nuclear "triathlon" of a simulated cargo of spent fuel rods over 14,500 mi to record the stress and jolts that fuel undergoes in transit.

Fractal design boosts efficiency of concentrating solar power receivers

Michael Irving October 25, 2017

Concentrating solar power (CSP) plants can be a key part of a renewable energy strategy, but progress is often focused on larger facilities. Now, engineers from Sandia National Laboratories are improving the efficiency of smaller plants, designing a new receiver that can absorb much more sunlight.

Giant gas gun replaces explosives in rocket part testing

Michael Franco August 31, 2017

Sandia National Laboratories is up to big things. After having recently replicated the energy found around black holes, the facility has just delivered proof of concept for a method of testing rocket parts using a 60-foot-long (18 m) compressed nitrogen gun that makes the process greener and safer.

Monster x-ray machine blasts apart black hole theory

Michael Franco August 30, 2017

Using the most powerful X-ray-generating machine on the planet, researchers have reproduced what happens to matter just before it is devoured by a black hole. Their findings show that a long-standing theory regarding the giant gravitational sinkholes may be completely wrong.

Sandia Labs turns to tritium in quest for fusion power

David Szondy November 10, 2016

Sandia National Laboratories is raising the stakes in its quest to develop fusion power by introducing tritium into its experiments with its Z machine. Tritium, the heaviest of the three hydrogen isotopes promises to boost energy output by a factor of 500.

Two fast neutron radiation-effects cassettes aim toward the center of the containment system for tritium within ...

Bubble-like "Memzyme" increases speed and efficiency of carbon capture

Michael Irving September 4, 2016

Capturing carbon emissions at the source is an important weapon in the fight against climate change. Now scientists have developed an efficient low-cost technique that makes use of an ultra-thin membrane, like a bubble, to filter CO2 out of flue gas.
