The Society of Physics Students
To the left, students are working on our Tesla coil. The Tesla coil is in the final stages, students are just tuning the number of coils. The Society of Physics Students has many interesting projects.
Undergraduate Physics Program
Right now is a great time to study physics at Saint Louis University! Our faculty are friendly and we love working with undergraduate students! Our students work closely with professors on a senior research project over the course of three semesters. Undergraduate students are enouraged to get involved in research with our faculty as soon as possible. Faculty at Saint Louis University do research in a wide range of areas including nanotechnology, superconductivity, quantum information, relativity, and biophysics. We have something for young minds curious about physics!
Integrated and Applied Sciences Graduate Program
The Saint Louis University Department of Physics is now accepting applications for the Integrated and Applied Sciences (IAS) Ph.D. program in Nanomaterials and Condensed Matter Physics track. Please contact Dr. Kuljanishvili, Dr. Solenov, or Dr. Wisbey for more information. Faculty are willing to work with students to apply for funding with National Science Foundation through the Graduate Research Fellowship Program (GRFP).
A Two-Step Method for Transferring Single-Walled Carbon Nanotubes onto a Hydrogel Substrate

Carbon nanotube (CNT)-hydrogel nanocomposites are beneficial for various biomedical applications, such as nerve regeneration, tissue engineering, sensing, or implant coatings. Still, there are impediments to developing nanocomposites, including attaining a homogeneous CNT-polymer dispersion or patterning CNTs on hydrogels. While few approaches have been reported for patterning CNTs on polymeric substrates, these methods include high temperature, high vacuum or utilize a sacrificial layer and, hence, are incompatible with hydrogels as they lead to irreversible collapse in hydrogel structure. In this study, a novel two-step method is designed to transfer CNTs onto hydrogels. First, dense CNTs are grown on quartz substrates. Subsequently, hydrogel solutions are deposited on the quartz-grown CNTs. Upon gelation, the hydrogel with transferred CNTs is peeled from the quartz. Successful transfer is confirmed by scanning electron microscopy and indirectly by cell attachment. The efficient transfer is attributed to p-interactions pregelation between the polymers in solution and the CNTs.

The ability to construct heterostructures that consist of layered transition metal dichalcogenides materials (MX2) in a controlled fashion provides an attractive solution for materials design and device applications. For nanotechnology applications it is important to control the shape, geometry and precise position of the grown heterostructure assemblies on a variety of substrates. In this study, we developed a "direct writing" technique to fabricate arrays of WS2/MoS2 and MoS2/WS2/MoS2 heterostructures at predefined locations on a silicon substrate in a controlled fashion. Water based precursor inks were implemented to ensure the formation of quality heterostructure surfaces which are free of residual polymer contaminants. With this technique we demonstrate an attractive and scalable technology with unique capabilities for precise growth of dissimilar MX2 materials, layered either in a vertical or lateral arrangement.
