Direct Observation of Topologically Enhanced Interfacial Miscibility in Ring–Linear Polymers

Abstract Cyclic polymers, lacking chain ends, exhibit unique behavior when blended with linear analogues. In such cyclic/linear mixtures, cyclic polymers permit chain threading, wherein linear chains penetrate the ring-like structure, increasing entropy and enhancing interfacial...

Vacuum-induced evaporation and heat transfer in a simulated single-assembly spent nuclear fuel canister

Vacuum drying is a critical process for the long-term integrity of spent nuclear fuel (SNF) storage. This study presents a systematic thermal-hydraulic evaluation comparing the conventional step-wise decompression method with a next-generation variable exhaust flow rate operation...
