The Science of Friction on Graphene

Sliding on flexible graphene surfaces has been uncharted territory until now, Graphene, a two-dimensional form of carbon sheets just one atom thick, has been the subject of widespread research, in large part because of its […]

Vanishing Friction

Illustration: Christine Daniloff/MIT and Alexei Bylinkskii A new technique tunes friction between two surfaces, to the point where friction can vanish. MIT researchers developed a frictional interface at the atomic level. The blue corrugated surface […]

Zeroing in on ZDDP tribofilm growth

Models for the stress-activated growth of tribofilms from ZDDP were modified to include wear. TWO RECENT CUTTING EDGE ARTICLES reported on work that showed the growth rates of tribofilms from ZDDP were accelerated by contact […]

Atomistic Tribology
Nanotechnology Flight Test

Mastering the intricacies of controlling matter at the nanoscale level is part of a revolutionary quest to apply nanotechnology to benefit industrial processes. A key element of that technology is the use of carbon nanotubes. […]

Say “modeling” not “simulation”

Richard M. Stallman, founder and president of the Free Software Foundation and founding father of the GNU Project, has a long been repeating “say GNU, not Linux” although he has not had much success. In the same sense, from this corner […]

Keeping the Wind in Your Sails

Just like any mechanical device, a wind energy system needs timely, appropriate lubrication in order to function reliably and predictably. Wind turbines routinely withstand extremely demanding conditions: vibration, high mechanical loads, contamination and moisture are […]
