Dr. Hong Liang is an associate professor in the Mechanical Engineering
Department of the University of Alaska, Fairbanks. The primary focus of
her research is the study of nanostructured materials and nanotribology.
Of primary interest is the understanding of friction and wear at the
nanometer scale. In the fall of 2002 Dr. Liang needed to purchase an
AFM system for her research and for training students in the emerging
disciplines of Nanotechnology.
Dr. Liang and her colleagues at the University of Alaska, Fairbanks
initiated an exhaustive search of the commercially available atomic
force microscopes and decided to purchase the Nano-R™ AFM from
Pacific Nanotechnology. Their primary reason for purchasing the
Nano-R™ AFM included meeting their applications requirements
at a price that was within their budget.
After the installation of the Nano-R™ at University of Alaska,
Fairbanks, students began measuring useful images immediately. Both
graduate and postgraduate students enjoy operating the Nano-R™
AFM. During the first six months of ownership the University of Alaska
research groups have studied metals, semiconductors and nanoparticles
with their Nano-R™ AFM system.
