A 2025 Scientific Reports study turns peroxide-bearing products of fatty-acid autoxidation into macroinitiators for branched PHB–poly(fatty acid)–PMMA copolymers, then tests the resulting architecture using complementary spectroscopic, chromatographic, thermal, and microscopy measurements.

All-atom molecular-dynamics simulations compare pristine and functionalized graphene quantum dots in bisphenol-F epoxy, predicting chemistry-dependent shifts in glass-transition behavior while most CTE changes remain statistically insignificant.

I’m honored to have been invited by the American Society of Mechanical Engineers (ASME) as a Rising Star of Mechanical Engineering. I will be presenting at the ASME International Mechanical Engineering Congress and Exposition (IMECE) in Memphis, Tennessee, on November 18, 2025. I look forward to attending IMECE, sharing my research, and connecting with colleagues […]

Synthesis and Characterization of a Novel Membrane Based on Poly (2-Ethyl Oxazoline) and Poly (Propylene) Graft Copolymer for Potential Food Packaging and Medical Applications Baki Hazer, Zeynep Karahaliloglu, Özgür Keleş* Abstract Cost-effective olefin polymers have been producing several hundred million tons of olefins each year. They have material properties suitable for packaging and biomedical applications. […]

Optimizing Epoxy Nanocomposites with Oxidized Graphene Quantum Dots for Superior Mechanical Performance: A Molecular Dynamics ApproachPrathamesh P. Deshpande,* Robert Chan-Jobe, Josh Kemppainen, Gregory M. Odegard, and Ozgur Keles* ABSTRACT: Due to their excellent mechanical properties epoxy composites arewidely used in low-density applications. However the brittle epoxy matrix oftenserves as the principal failure point. Matrix enhancements […]

Comparison of the Macro Chain Transfer Agent and the Macro Azo Initiator Based on the Poly(3-hydroxy Butyrate) in the Polymerization Kinetics of Methyl MethacrylateBaki Hazer and Özgür Keleş You can access here link.Abstract: Poly(3-hydroxybutyrate) (PHB) derivatives are attractive for sustainable polymer production, yet their role in controlling radical polymerization kinetics remains underexplored. In this study, […]
