RESEARCH HIGHLIGHTS

We develop comprehensive in situ/operando methodologies for the characterization of nanomaterials fabrication such as the chemical vapor deposition (CVD) of carbon nanotubes (CNTs).  Using environmental transmission electron microscopy (E-TEM), and small angle X-ray scattering (SAXS), we elucidate thin-film dewetting, catalytic activation/deactivation, and population growth dynamics until termination.

OUR TEAM

We are a diverse team of researchers led by Dr. Mostafa Bedewy. We collaborate with on campus groups at Pitt (both within Engineering and in other Pitt schools). Further, we have off-campus collaborations at other universities, including MIT, Harvard, and Cornell, as well as at national labs, including Brookhaven.  We are always looking for talented individuals to join our team.  If you are interested, contact Dr. Bedewy ([email protected])

The NanoProduct Lab, also known as the Bedewy Research Group, at the University of Pittsburgh was established by Dr. Mostafa Bedewy in fall 2016.  We are located in Benedum Hall in the Swanson School of Engineering (SSoE).  We are part of the Department of Industrial Engineering (IE), and we are also affiliated/associated with the Department of Chemical and Petroleum Engineering, the Department of Mechanical Engineering and Materials Science, the University of Pittsburgh Center for Advanced Manufacturing (UPCAM),  the Center for Energy,  the Mascaro Center for Sustainable Innovation (MCSI), the Petersen Institute of NanoScience and Engineering (PINSE), Pittsburgh Quantum Institute, and the Institute for Cyber Law, Policy and Security (Pitt Cyber).

Our group focuses on fundamental experimental research at the interface between nanoscience, biotechnology, and manufacturing engineering. We make basic scientific discoveries and applied technological developments in the broad area of advanced manufacturing at multiple length scales.

We design novel solutions that impact major societal challenges in areas related to  energy, healthcare, and the environment.
