The Synthesis and Characterization of Homemade Explosives to Support Test and Evaluation Tyler Maxwell, Ph.D. Lead Chemist Tyndall Reactive Materials Group Applied Research Associates Inc. 430 West 5th Street, Suite 700 Panama City, FL 32401 The protection of transportation systems and freedom of movement for people and commerce is essential for a nation to function. The United States government is committed to preventing future terrorist attacks such as those that occurred on September 11th 2001. To support this mission, basic and applied research on homemade explosives (HME) is critical for the safety of the traveling public as HMEs have been used in attacks against the US and abroad. The Tyndall Reactive Materials Group (TRMG) has been working on behalf of the US government to synthesize, analyze, and produce large quantities of HME for testing and evaluation since 2005. The process for safely manufacturing and characterizing HMEs at TRMG is described as well as some of the working principles behind contraband detection technologies currently deployed and in development. Blast characterization methods are also described for evaluating the detonability and terminal performance of HMEs.
Come learn some interesting chemistry and socialize with your fellow chemists. We look forward to seeing you all there!

Orlando Section students traveled to the Spring Meeting in Orlando
The Orlando Section of the ACS sponsored four students with Student Travel Awards, thanks in part to a generous donation from Dr. Darlene Slattery, retired longâtime Orlando Section Councilor and the 2025 Gordon L. Nelson Award recipient.
Moses Mayonu (pictured right), PhD Candidate in Chemistry at the Florida Institute of Technology, stated that, âThis experience provided me with extensive networking opportunities with researchers across the United States and the broader international scientific community. Engaging with distinguished professors offered valuable academic perspectives, while connections with students from both academic and industrial backgrounds have since contributed meaningfully to my ongoing research. A key highlight was the metabolomics data analysis bootcamp on March 25, 2026, which equipped me with critical analytical skills that will enhance my research approach and support my career development.â
Macayla Marr Barnett, undergraduate researcher at UCF (pictured left with advisor Dr. Nicole Lapeyrouse), shared that âthe award allowed me to present at the 2026 Spring ACS Conference and share me and my research teamâs most recent updates on STEM Identity. I love sharing and learning more about chemistry research and am so privileged to be able to connect with others in the community.â
Allison Lloyd (pictured right), PhD candidate at UCF shared that, âThis year was the 150th anniversary of the conference, which resulted in keynote speakers Iâd never thought Iâd get the opportunity to hear from. I attended the keynote given by Dr. Jennifer Doudna, Nobel Prize-winner and co-inventor of CRISPR technology, which was the kickoff keynote for the conference. From that point forward, I presented a poster during the evening general poster session and the Sci-Mix poster session, in which I was approached by other researchers working on quantum dots. It was great to explain to them my own work on quantum dots, to have my work challenged and questioned by them, and to receive advice regarding experts in the field I could consult to continue with my work. Later in the week, I attended another keynote given by the Nobel Prize winner Dr. Moungi Bawendi for his contributions to quantum dots â the same field I had been presenting research in!â
Preeti Maiti (pictured left), a doctoral student at UCF, shared that, âI was selected to present a poster in the Biomaterials and Biointerfaces session under the Division of Colloid and Surface Chemistry. Presenting my poster provided an excellent opportunity for scientific exchange, allowing me to engage with researchers and gain valuable new ideas and perspectives.
In addition, I was selected to deliver an oral presentation in the Division of Biochemical Technology under the Product Formulation session. This experience offered significant insights and served as a valuable platform to effectively communicate my research to a broader scientific audience.â
Avogadro Award
In 2001, the Orlando Section established the Avogadro Award to be presented to an outstanding senior project at the State Science and Engineering Fair. Other Sections in Florida were encouraged to support the award and it is presented yearly as a joint effort.
The 2006 award winner is Nicholas R. Stan (pictured right), a student at Alexander W. Dreyfoos School of the Arts in West Palm Beach. Nicholasâ project was entitled âEnhancing the Oncotoxic Effects of Mitochondrial-targeting D-(KLAKLAK)2 Peptide by Improving Cell Membrane Permeability via Chemical Conjugation with Imidazopyidinium.â The judges in the senior chemistry section unanimously chose this project because of its strong chemistry content and the obvious knowledge of the student.
The Orlando Section extends its gratitude to Darlene Slattery and DK Weerasinghe for judging the fair and awarding the Avogadro Award along with thanks to the Pensacola Section and the South Florida Section of ACS for contributing to the monetary award for the prize.
Abstract
Prior research has indicated that the synthetic peptide D-(KLAKLAK)2 and its analogues (D-KLAKLAK and D-KLAK) exhibit potent cancer toxicity (oncotoxicity) and pro-apoptotic activity when internalized in mammalian cancer cells. The limitations of these peptides as therapeutic agents, however, are cancer specificity and membrane permeability. Research on tumor-homing peptides to attach to these kinds of peptides has had relative success in conferring specificity, but remain inefficient in promoting membrane permeability. Therefore, the only remaining problem is membrane permeability. The study conducted investigates chemical grafting of IP+ (imidazopyridinium) on to D-(KLAKLAK)2 and its analogues, and its effect on cellular permeability. IP+ is a heterocycle designed to facilitate the diffusion of large peptides across the cell membrane, and this study tested if grafting IP+ onto D-(KLAKLAK)2 and its analogues would improve its ability to diffuse across the cell membrane, which could aid in the development of a cancer therapeutic based on this peptide or others. Experimental methods included preparing D-(KLAKLAK)2 and its analogues, and grafting IP+ and a chloroalkane tag onto them. The effects of IP+ grafting were evaluated by running Chloroalkane Penetration Assays (CAQPA) on HEK293 cells in order to assess to what degree the peptides with or without IP+ could access the cytosol of the cells. Results indicated that IP+ significantly enhanced the intracellular localization of D-(KLAKLAK)2 and D-KLAK compared to controls lacking IP+. These results support the hypothesis and suggest that combining D-(KLAKLAK)2, a tumor-targeting peptide, and IP+ may provide a promising approach for developing broad-spectrum cancer therapeutics in the future.
