Exploring the Structures and Properties of Strongly Bound Atomic Clusters

Thursday, April 15th @ 7:00 pm

Join Virtually via Zoom
(Meeting ID TBA)

Speaker: Dr. Jonathan T. Lyon, Murray State University

Abstract: Strongly bound atomic clusters are often used as ideal models for the active sites in bulk material. Despite the increased scientific interest in cluster sized particles, open questions remain about the structure, stability, and related properties of specific cluster systems. We present here recent investigations on clusters containing between 2 and 25 atoms. Theoretically, we utilize global optimization procedures to locate new local and global minima candidates. These structures are further optimized with different density functional and ab initio techniques and electronic, vibrational, and internal bonding properties are explored. Complementary experimental matrix isolation infrared experiments currently being assembled will also be discussed. Specific systems presented here include transition metal clusters, doped semiconductor clusters, and metal hydride clusters. Items of particular interest with these systems include novel cluster geometries, cluster size/stability relationships, exohedral to endoheral doped cluster transitions, and hydrogen adsorption energetics.

Chemists Celebrate Earth Week April 18-24th

“Reducing Our Footprint with Chemistry”

For years, chemists have promoted a better world through recyclable plastics, cleaner-burning fuels, phosphate-free detergents, environmental monitoring and green chemistry initiatives. Each year, the American Chemical Society highlights these initiatives and chooses a specific theme to help focus the observance of Chemists Celebrate Earth Week (CCEW). This year’s theme is, “Reducing Our Footprint Through Chemistry”.

January 2021 – Message from the Chair

Happy New Year KLS Family,

We certainly share our 2021 resolution contributing to end this pandemic and accomplish many exciting projects. Make 2021 the year YOU get involved! We have a range of volunteer and leadership opportunities available for you to engage with the KLS – from one-time events to programming to awards to executive committee positions, we invite your participation.

I would like to thank Dr. Kevin Miller’s leadership and all volunteers last year despite the global turmoil. I look forward to working with you all this year. The first KLS executive committee of this year met virtually on January 11th and discussed several agenda including tentative spring meetings, grant/report, budget, and committee members for the 2021 term. In January’s virtual meeting (scheduled for 25th), Dr. Grace Eder from Murray State will be presenting 1-3 dimensional polymer materials for sustainability applications. Please join us on 25th at 7:00 PM.

We are planning to have a panel on chemistry careers in the industry for current students and other recent graduates who may have an interest in joining the industry. This panel will be virtual (open to everyone) and involve several recent graduates from our area institutions who are currently in the chemical industry. The event is sponsored in part by an IPG (Innovative Project Grant) from the American Chemical Society. Please contact Dr. Miller or me to share any suggestions.

As part of the “Senior Chemists” project sponsored by the ACS Senior Chemists Committee 2020 Mini-Grant, our four Chemistry senior students interviewed Prof. Harris Fannin, Mrs. Erica Gray, and Dr. Fred Allen. Please visit our KLS webpage and feel free to publicize those amazing interviews!

September 2020 – Message from the Chair

Greetings KLS members!

Welcome to what will be the virtual/hybrid edition of our fall calendar. I hope everyone had a safe summer. While we weren’t able to have a welcome back picnic this year, we do have a few exciting events shaping up this fall. To start us off we will have a hybrid September presentation by Lyndi Strange, a recent graduate of Union University, on transition metal dichalcogenides. Many thanks to Prof. Randy Johnston for setting up this meeting. I know that many of us are either going to Zoom into the meeting or conduct virtual viewings at our respective locations, but you are also welcome to attend in person. In addition to the September meeting, we are planning on having a panel later on this fall for current students and other recent graduates who may have interest in attending graduate school. This panel will be virtual (open to everyone) and involve several recent graduates from our area institutions who are currently in graduate school. The event is sponsored in part by an IPG (Innovative Project Grant) from the American Chemical Society. A similar event is in the works for the spring that will focus on chemistry careers in industry. Finally, we are working on some creative programming for National Chemistry Week. So please tune in for the discussion at Union University and let us know if you have any questions, concerns or ideas!

Thanks!
Kevin Miller, 2020 KLS Chair

Program: Transition metal dichalcogenides for applications in hydrogen evolution reaction, CO2 reduction, and photoluminescence spectroelectrochemistry

Speaker: Lyndi Strange, 5th Year PhD Candidate at University of Alabama

Abstract:  Transition metal dichalcogenides (TMDs) are semiconductors of the form MX2, where M is a transition metal (Mo, W, etc.) and X is a chalcogen atom. They are typically structured in hexagonal layers of M atoms sandwiched between two layers of X atoms. Two-dimensional TMDs (2D-TMDs) consist of a single layer of atoms have the structure X-M-X and have electronic properties that differ from the bulk material. For instance, the bandgap of MoS2 changes from an indirect bandgap in the bulk to a direct bandgap as a monolayer. In the search for better catalysts for renewable energy, TMDs have emerged as an interesting and promising catalyst for several avenues of alternate energy such as photovoltaic water splitting anodes, hydrogen evolution reaction, CO2 reduction, photovoltaic absorber layers, and protective layers for photovoltaic devices. The structure of the TMDs can also be tuned at the monolayer level to increase catalytic activity by doping and introducing defects, which has been shown increase activity towards electrocatalytic hydrogen reduction. The highly tunable structure also leads to tunable optical properties that in useful in next generation optoelectronics such as light emitting diodes (LEDs), field effect transistors (FETs), and ultra-sensitive molecular sensing due to their unique surface-sensitive optical properties. Learning how the structure affects the catalytic and optical properties serves as an important area of research in order tune TMDs to produce more efficient catalysts and serve in various optical applications. This research presentation will cover the following projects: 1) the proton reduction activity of 2D and bulk MoS2 using scanning electrochemical cell microscopy (SECM) and other electroanalytical techniques such as rotating-ring disk electrode and Tafel slope analysis; 2) examining the redox properties of 2D MoS2 using photoluminescence spectroelectrochemistry and scanning electrochemical cell microscopy (SECCM); 3) using aqueous liquid-phase exfoliation technique to produce MoS2 thin films for use in CO2 reduction and the characterization of the reaction products.

Speaker Bio:  Lyndi Strange graduated from Union University in 2016 with a B.S. in chemistry. She did two years of summer research under Dr. Joshua Williams studying guest-host relationships in dye included crystals. She also did a summer REU program at the University of Oregon under Dr. Shannon Boettcher studying the electronic properties of GaAs microstructures grown using close-spaced vapor transport (CSVT), which inspired her to pursue electrochemistry as her focus in graduate school. She is currently a PhD candidate entering into her 5th year at the University of Alabama studying under Dr. Shanlin Pan. Her research focus at UA has focused on transition metal dichalcogenides for use in alternative energy and spectroelectrochemical applications. She has co-authored and authored articles in the ACS Energy Letters, the Journal of Physical Chemistry Letters, and has submitted a review article Journal of the Electrochemical Society. During her tenure at UA, she also participated in a summer internship at Sandia National Laboratories in Albuquerque, NM, which lead to a year-round position. She plans to graduate from the University of Alabama in Summer 2021 and hopefully continue her Sandia employment as a post-doctoral appointee.
