Magnetically Stimulated Flow Patterns Offer Strategy for Heat-Transfer Problems

Sandia’s Jim Martin and Kyle Solis (both in the Nanoscale Sciences Dept.) have discovered how to harness magnetic fields to create vigorous, organized fluid flows in particle suspensions. The magnetically stimulated flows offer an alternative when heat transfer is difficult because they overcome natural convection limits. Martin and Solis even demonstrated a heat-transfer valve that […]

CRF Summer Undergraduate Internship Opportunities – Apply by January 10, 2014

The Combustion Research Facility (CRF) is seeking undergraduate and community college interns for 10-week appointments in summer 2014. Interns will be paired with a CRF scientist to conduct experimental, computational, or modeling research related to CRF programs. Applicants must be U.S. citizens majoring in math, physical science, or engineering, with a minimum GPA of 3.2/4.0. […]

Lignin-Feasting Microbe Holds Promise for Biofuels

Nature designed lignin, the tough woody polymer in the walls of plant cells, to bind and protect the cellulose sugars that plants use for energy. For this reason, lignin is a major challenge for those who would extract those same plant sugars and use them to make advanced biofuels. As part of their search for […]

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 […]
