Welcome to the Patrick Group website.

Here you will find information about our research program and members of the group, past and present.  Our research spans a range of topics centered in the emerging field of nanoscience, which is the study of objects and phenomena at nanometer length scales - i.e. at the scale of atoms and molecules. 

Our main interest is in developing new ways to manipulate and organize matter at nanometer scales using liquid crystals.  The systems we study include organic semiconductors for applications as inexpensive, flexible solar cells and displays; carbon nanotubes and other nanoparticles for applications in molecular electronics; and organic thin films.  

Almost all of our research involves liquid crystals. These fascinating materials combine properties of both liquids and crystals: they flow like ordinary liquids, but are ordered similar to crystals.  Chances are you're looking at a liquid crystal film right now - in your computer screen.  More information about liquid crystals can be found here.

Our group is well equipped with a variety of specialized instrumentation, including including scanning tunneling, atomic force, fourier-transform infrared, and polarizing microscopes.  A short description of these techniques is given here.

Nanoscience is an interdisciplinary subject, and this is reflected in our work, which encompasses areas ranging from materials science to analytical chemistry.  Group members have had backgrounds in chemistry, biochemistry, computer science, engineering and physics.  Past members have gone on to careers in many fields, from the semiconductor industry, to biological sciences and high school teaching.  If you are interested in joining the Patrick Group, more information for prospective members is available here.
