Numerical simulation on deposition evolution of natural gas hydrate in pipeline

You-qi chuyun, 2022
The traditional Euler-Euler fluid model is to predict the flow and deposition of two phases by approximating the hydrate particles as a fluid phase, but does not consider the effect of particle formation caused by phase change in the flow process. Herein,

Biodegradable and Recyclable Luminescent Mixed‐Matrix‐Membranes, Hydrogels, and Cryogels based on Nanoscale Metal‐Organic Frameworks and Biopolymers

Advanced Functional Materials, EarlyView.
The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...
