Argonne principal mechanical engineer Sibendu Som (left) and computational scientist Raymond Bair discuss combustion engine simulations conducted by the Virtual Engine Research Institute and Fuels Initiative (VERIFI). The initiative will be running massive simulations on Argonne’s Mira supercomputer to gain further insight into the inner workings of combustion engines. (Click image to view larger.)
Argonne pushing boundaries of computing in engine simulations

Researchers at Argonne will be testing the limits of computing horsepower this year with a new simulation project from the Virtual Engine Research Institute and Fuels Initiative that will harness 60 million computer core hours to dispel uncertainties and pave the way to more effective engine simulations.

Argonne researchers Osman Eryilmaz (left) and Gerald Jeka (right) recover industrial parts from the large-scale ultra-fast boriding furnace after a successful boriding treatment. This process for extending the lifetime of mechanical parts, which just received its U.S. patent, saves time, money and energy compared to conventional technique, and even alleviates environmental concerns.

Erdemir receives patent for ultra-fast surface hardening technology

A newly patented technology by Distinguished Fellow Ali Erdemir and his team at Argonne National Laboratory could greatly extend the lifetime of mechanical parts. The team designed a device for ultra-fast boriding, which compared to conventional boriding techniques saves time, money and energy, and even alleviates environmental concerns.

A copper tetramer catalyst created by researchers at Argonne National Laboratory may help capture and convert carbon dioxide in a way that ultimately saves energy. It consists of small clusters of four copper atoms each, supported on a thin film of aluminum oxide. These catalysts work by binding to carbon dioxide molecules, orienting them in a way that is ideal for chemical reactions. The structure of the copper tetramer is such that most of its binding sites are open, which means it can attach more strongly to carbon dioxide and can better accelerate the conversion.

Copper clusters capture and convert carbon dioxide to make fuel

The chemical reactions that make methanol from carbon dioxide rely on a catalyst to speed up the conversion, and Argonne scientists identified a new material that could fill this role. With its unique structure, this catalyst can capture and convert carbon dioxide in a way that ultimately saves energy.
