Real-Time Dual-Probe Monitoring and Correlation of FBRM and PVM Measurements during PUF Microcapsule Formation Ozeroglu, Basak; Özkan, Necati (2026-01-19) Microencapsulation enables the protection and controlled release of reactive liquids, however most characterization methods capture only endpoint properties. To address this gap, a real-time dual-probe approach using Focus...
Influence of conventional and supramolecular gellants on the rheological properties of JP-10 gel fuels Ozyetis, Hatice; Koc, Ahmet; Esiyok, Haci; Özkan, Necati (2026-01-01) The effects of a conventional gellant and different types of supramolecular gellants on the rheological properties of JP-10 gel fuels are studied. Various concentrations of 1,2:5,6-di-O-isopropylidene-D-mannitol (IPM) and ...
Investigating the Multistep Polymerization Reactions of DCPD with Grubbs’ First-Generation Catalyst Özeroğlu, Başak; Özkan, Necati (2025-01-01) Self-healing polymer composites using Grubbs’ first-generation (G1) catalyst and dicyclopentadiene (DCPD) as the healing monomer are widely used in self-healing applications. In such systems, DCPD released from ruptured mi...
Enhancing the performance of HTPB-IPDI-based polyurethane composite liner through effective carbon black dispersion**

Aslan, Onurcan; Atalar, Taner; Atınç Yılmaz, Gürkan; Özkan, Necati (2023-01-01)

This study aims to improve the dispersion of Carbon Black (CB) filled Hydroxyl-Terminated Polybutadiene (HTPB)-Isophorone Diisocyanate (IPDI) based polyurethane liner by both adding a dispersant and developing a production...
