Research
Areas: Fluid transport at micro- and nanoscales;
materials processing and manufacturing (crystal
growth, chemical vapor deposition, laser processing and manufacturing,
charge transport and related issues in semi-conductors, photon
generation, control and transport in optical fibers); integrating
advanced materials into the design of micro and nanoscale mechanical
systems (utilizing and integrating smart materials into MEMS);
coupling of phenomena
at nanoscale with those at larger scales (multi-scale simulations),
such as multiscale modeling of radiation damage and degradation processes in
materials exposed to nuclear reactor environments; visualization of phenomena
at small length scales; multi-phase
flows in microscale systems; nuclear
techniques for atomic scale materials characterization.

View of Sub-Micron thick Thermopile Assembly Embedded
in Polymer Electrolyte
Working
in collaboration with Prof. S Tadigadapa of Electrical
Engineering, Dr. Mench is developing sub-micron sized
temperature sensors with shadow masking, an e-beam
evaporator and electro discharge machining (EDM)
techniques.
These
sensor arrays are embedded within the 50 micron thick
polymer electrolyte at precise locations inside a fuel
cell, revealing temperature distribution data, as well
as enabling calculating thermal transport parameters
in the thin-film media.

Nanotensilometer
- Dr. Aman Haque
The
nanotensilometer can perform tensile tests on freestanding
specimens that are 30-100 nanometer thick. The specimen
is integrated with force and displacement sensors
so that the test can be performed in-situ in a transmission
electron microscope. Thus, one can observe nanoscale
deformation and failure processes in the specimen
as well as measure the stress-strain states, which
has not been possible before.
