John Anthony and Chad Risko have joined forces in a recent publication in the ACS Journal Chemistry of Materials titled "Dynamics, Miscibility, and Morphology in Polymer:Molecule Blends: The Impact of Chemical Functionality.” Drs. Anthony and Risko are based in Lab 2 at UK CAER and also hold faculty appointments in the UK College of Arts & Sciences Department of Chemistry.
Based on a series of acceptors constructed from trialkylsilylethynyl-substituted pentacenes designed and synthesized in the Anthony laboratory, the study presents a computational chemistry investigation of polymer:molecule blends with the polymer donor poly(3-hexylthiophene) (P3HT). Essential connections are made between the chemical structure of the acene acceptor and the nanoscale properties of the polymer:molecule blend, which include polymer and molecular diffusivity, donor–acceptor packing and interfacial (contact) area, and miscibility. The results point to the very significant role that seemingly modest changes in chemical structure play during the formation of polymer:molecule blend morphologies, and how molecule design can be used to control critical aspects of thin-film morphology.

A special issue of the journal, Topics in Catalysis, has been published by Springer publisher. The issue includes a collection of papers authored by many of the speakers who attended a three-day awards symposium to honor Burtron H. Davis at the American Chemical Society (ACS) Spring National Meeting in New Orleans on April 8-10, 2013. Additionally, other authors who were unable to attend, but wanted to make a contribution are included.
"The presentations reflected an array of catalytic reactions for a wide range of energy applications ranging from traditional reactions in petroleum refining to alternative fuels research (including Fischer–Tropsch synthesis, methanol synthesis, hydrogen production and storage, and the upgrading of chemicals derived from biorenewable resources) to catalytic applications in rocket propulsion. The scope of the presentations and discussions reflects the far-reaching impact that Burt Davis has had on the catalysis and fuels research community".
Guest editors, Uschi Graham and Gary Jacobs, two scientists that work with Dr. Davis from the University of Kentucky Center for Applied Energy Research Clean Fuels & Chemicals research group, wrote the foreword for this special issue
Dr. Davis, Associate Director of the CFC group at the UK CAER, is the recipient of the prestigious 2013 American Chemical Society’s Distinguished Researcher Award in Petroleum Chemistry.
