Detailed Information

About Me: 

The main thrust of Dr. Mosleh′s research is surface engineering, surface treatment, wear mechanisms, and lubrication. The role of surface texturing, near surface and bulk characteristics, and mechanics of surface interactions at nano, micro and macro scales are investigated. Other research activities include development of novel nanolubricants and nanofluids for thermal and lubrication management, study of the role of surface defects and topography of ceramics such as silicon nitride on fatigue failure, development of metal and ceramic matrix composites for improved mechanical and thermal properties.

Surface Engineering and Nanofluids Laboratory (SENL)

Dr. Mosleh is the founder of Surface Engineering and Nanofluids Laboratory (SENL) in the Department of Mechanical Engineering.
Research in SENL focuses on understanding the interactions of contacting surfaces in different scales and devising innovative engineering solutions to reduce/eliminate their degradation over time. Surface engineering techniques are being used in a variety of applications including automotive, aerospace, power, electronic, biomedical, textile, petroleum, chemical, machine tools and construction industries. The main thrusts of research include cutting nanofluids for manufacturing processes, nanofluids for thermal and lubrication management, nanolubricants for energy efficiency in engines and transmissions, vehicle tribology, rolling contact fatigue, hybrid bearings, surface texturing, contact mechanics, and nanotribology.

During the past several years, numerous master and doctoral graduates have conducted their research in this laboratory under the PI’s supervision. Some of the major equipment/instrumentations are:

  • Koehler TR-30H four-ball tester (10,000 rpm and 10,000 N) for ASTM standards D-2783, D-2266, D-
    2596, D-4172 and D-5183 and IP-300 standard tests
  • Nano DeBEE High Pressure Homogenizer with 3 lt/hr capacity and pressure of 45,000 psi
  • Malvern Zetasizer Nano ZS with particle size range of 0.3 nm -10,000 nm
  • ThermTest TPS 500 for thermal conductivity & diffusivity of solids, fluids, pastes, and particles
  • Cambridge Viscosity VISCOlab 3000 for measurement of viscosity up to 175 C
  • Retsch Planetary Ball Mill PM200
  • Other equipment such as polishing machines, microbalances, rotary and back and forth tribotesters, a planetary ball mill and computers for data acquisition and computational needs
