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 ...

Multiobjective Operation of Ultra-Supercritical Boiler-Turbine Unit

IFAC-PapersOnLine, 2018
Abstract In order to optimize the economic objectives while regulating the ultra-supercritical boiler-turbine unit, an improved utopia tracking based multiobjective fuzzy model predictive control is proposed in this paper. This method uses a hierarchical structure, in which the quasi-infinite horizon fuzzy model predictive control is designed for the

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.
