Chemical Engineering

Research

Faculty research involves a broad range of activities that are at the frontiers of chemical engineering fundamentals and have application to relevant industrial problems. The faculty possess a broad range of experience and are routinely in contact with industrial counterparts. This contact enables them to convey a practical experience and perspective on many of the fundamental concepts that are presented in our programs.

Surface and Materials Studies Laboratory

The goals of the Surface and Materials Studies Laboratory are the development of advanced thin film materials and novel ultrahigh (UHV) vacuum synthesis processes as well as the improvement of existing process technologies. The materials of greatest interest are the wide bandgap semiconductors such as diamond, silicon carbide, and gallium nitride because of their numerous electronic and electrooptic applications. Research on these materials accounts for approximately 90% of the lab's funding. The lab also provides support for other material related programs at WVU. These include the synthesis of ferric sulfide catalysts for coal liquefaction, chemical vapor deposition of oxidant resistant silicon nitride coatings for silicon carbide fibers, and stress induced failure mechanisms for super alloys. As a service, primarily to industrial clients, the lab occasionally provides surface analyses to aid in failure analysis.

The basic philosophy of the lab is that an understanding of the surface chemistry associated with thin film nucleation and growth is essential to the development of novel synthesis processes and the improvement of existing processes. Consequently, the approach adopted by the lab is highly interdisciplinary and spans the range from basic to applied materials science and engineering.
