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

open access: yesAdvanced 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 ...

Energy Sovereignty in Marine Spaces [PDF]

open access: yesThe International Journal of Marine and Coastal Law, 2014
The term “energy sovereignty” is used with differing emphases to describe a State’s rights or assertions over energy resources and supplies. Given the importance of offshore energy developments, particularly in the field of renewables, this article explores the meaning of energy sovereignty, arguing that more complex, cooperative approaches towards ...
