Some Important Contributions:
In tribology and mechanical properties of metals; theory of crystal defects, crystal plasticity,
and electric contacts.
Invented metal-fiber brushes as contacts for electric motor
which have, for example, applications for high-speed (300 mph) magnetically levitated trains.
