Sandia and Atlas-Copco Secoroc Advance to Phase 2 in Their Geothermal Energy Project

In 2012, the partnership between Sandia and Atlas-Copco Secoroc was awarded a $3.4M DOE grant to develop a down-the-hole (DTH) hammer capable of low-cost, high-production drilling in the extreme heat of deep geothermal wells. The overall DOE goal is to increase the feasibility of geothermal energy production by lowering the cost and financial risk associated [...]

Coupling Local to Nonlocal Continuum Models

Nonlocality, incorporating a length scale within the equations of mechanics, is increasingly recognized as an essential aspect of high-fidelity modeling of the fracture and failure of solids. The nonlocal peridynamic model, while providing the key advantage of unguided, autonomous crack growth, is computationally slower than the local finite-element method, motivating the search for an accurate [...]

Three-Dimensional Graphene Architectures

The mechanical strength and electron mobility of graphene has made it a novel material for a new generation of electronic devices, batteries, and sensors. Currently graphene is predominately grown on 2-D substrates. We have recently reported on a method to make 3-D graphene from interferometric lithographically patterned porous carbon electrodes that have been coated with [...]

Jerry Simmons Is One of Three Researchers Named as Laboratory Fellows

This status is reserved for those who are nationally or internationally recognized pioneers in their fields. It is considered a promotion to the highest level of R&D staff, equivalent to the level of management immediately below Sandia’s vice presidents. “The three new fellows have histories of sustained and equally distinguished accomplishments in their fields,” said [...]

SWiFT Commissioned to Study Wind Farm Optimization

The DOE, Sandia, and Texas Tech University (TTU) commissioned the DOE/Sandia Scaled Wind Farm Technology (SWiFT) facility on Tuesday, July 9th at the Reese Technology Center in Lubbock, Texas. SWiFT is the first public facility of its kind to use multiple wind turbines to measure how wind turbines interact with one another in a wind [...]
