Epoxy is one of the most important polymers preferred in various technological applications thanks to its good mechanical properties and lightness. However, their low thermal conductivity limits their usage areas. Inc...
Microwave absorption (MWA) materials such as graphene nanoplatelet (GNP)/epoxy are mostly used as coatings on existing structures without considering mechanical properties. In this work, we aim to enhance the mechanic...
3β-(p-iodobenzoyloxy)-16α,17α-epoxypregn-4-en-6,20-dione (7), C28H31O5I, was synthesized from the commercially available 16-dehydropregnenolone acetate. X-ray diffraction analysis of (1) demonstrated that it consis...
