Functionalized Graphene Films: Graphene, a 2 dimensional carbon material, has garnered much acclaim as a promising material for anything from touch screens to electronics. However, the lack of a band gap remains a barrier to its implementation in practical semiconductor applications. Functionalization of the material promises a route towards graphene semiconductor. Fluorine and hydrogen functionalization will be discussed, including routes, verification, and electronic properties of the functionalized materials.

How Mass Spectrometry is Used for Forensic and Clinical Analysis of Drugs of Abuse and the Team Behind the Analysis: An overview of forensic and clinical analysis of drugs of abuse including explanation of the principles, practices, and technology. We will also discuss the various methodologies, instrumentation and regulatory requirements involved. We will look at the different clients, markets and sample types that make up the bulk of biological analysis for drugs of abuse. Finally, we will talk about the team that is behind all of the work.

Drug Metabolites in Cord Blood: Tools for Predicting Neonatal Abstinence Syndrome: Buprenorphine is a semi-synthetic opioid used for the treatment of opioid dependence. Opioid use, including buprenorphine, has been increasing in recent years, in the general population and in pregnant women. Consequently, there has been a rise in frequency of neonatal abstinence syndrome (NAS), associated with buprenorphine use during pregnancy. The purpose of this study was to investigate correlations between buprenorphine and buprenorphine-metabolite concentrations in cord blood and onset of NAS in buprenorphine exposed newborns. Liquid chromatography–tandem mass spectrometry (LC–MS/MS) analysis of cord blood concentrations of buprenorphine and metabolites is an effective way to examine drug and metabolite levels in the infant at birth. Cord blood concentrations of the active norbuprenorphine metabolite and the inactive buprenorphine-glucuronide metabolite show promise in predicting necessity of treatment of NAS. These finding have implications in improving patient care and reducing healthcare costs if confirmed in a larger sample.

Using chemical insight to design and understand materials with unusual properties: metal fluorides that shrink on heating: Thermal expansion is a phenomenon that chemists do not often consider, and yet it is an important material’s characteristic for many applications. For example, Pyrex is used for laboratory glassware because it has a close to zero thermal coefficient. This makes the glassware resistant to failure when subject to rapid temperature changes. While most materials expand on heating, there are materials that shrink when heated and this unusual property can have value.
The origin of thermal expansion will be explained in terms of the structure, bonding and vibrational motion of solids. The use of this atomistic picture for the design and synthesis of metal fluorides that combine negative thermal expansion (shrinking on heating) with other unusual characteristics such as optical transparency over a wide range of wavelengths, molecular sieving and temperature dependent porosity will be presented.

Graduate School Opportunities and Current Research in the Kennemur Group
The Graduate School: With 32 collaborative research faculty, Florida State University offers doctoral degrees with an interdisciplinary approach to analytical, biological, inorganic, materials, organic, and physical chemistry. Students are offered cutting‐edge facilities to explore research needed to solve some of science’s most challenging demands in health, energy, and the environment and leave the department as competitive scholars in the current job market. A portion of this seminar will discuss these opportunities and also offer a glimpse into the life and demands of a doctoral candidate. Following the seminar, I am very happy to answer any questions you may have about FSU or graduate school in general.
Precision Polymer Chemistry Research: The ability for medium ring sized (5 ‐ 7 carbon) cycloalkenes to undergo ring‐opening metathesis polymerization (ROMP) is highly dependent upon the ring strain of the monomer to drive the thermodynamics of carbene exhange on the catalyst. To this extent, a majority of the research performedin the field of precision polyolefins with a linear, acyclic, hydrocarbon backbone has been withthermodynamically favorable cyclooctene monomers or the acyclic diene metathesis polymerization(ADMET) of linear dienes. Taking advantage of the chain‐growth mechanism opportunities provided by ROMP requires further investigation on the ability to polymerize monomers with much less ring strain (i.e. cyclopentenes). Utilizing temperatures lower than typically associated with ROMP (< 0 °C) drives conversion of low strain monomers and reduces chain transfer at the expense of reduced initiation and propagation activity. We recently reported the ability to achieve high molar mass (> 100 kg mol‐1) and moderate dispersity (~1.6) precision ethylene‐styrene copolymers with high styrene content in a repeatable fashion by ROMP of 4‐phenylcyclopentene at cold temperatures (‐20 °C). The ability to obtain polymers from substituted cyclopentenes opens a unique 5‐carbon topology spacing of precision branches along the backbone. Offering new materials with potentially advantageous properties and new segments to explore for block polymer and bottlebrush polymer analogs.
