Carbon dioxide concentration in Mediterranean greenhouses : how much lost production? [PDF]

, 2007
In the absence of artificial supply of carbon dioxide in the greenhouse environment, the CO2 absorbed in the process of photosynthesis must ultimately come from the external ambient through the ventilation openings.

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 ...

Photocatalytic Versus Stoichiometric Hydrogen Generation Using Mesoporous Silicon Catalysts: The Complex Role of Sacrificial Reagents

Advanced Functional Materials, EarlyView.
This study highlights the importance of accounting for stoichiometric hydrogen produced when utilizing Si photocatalysts. The stoichiometric contribution is sacrificial reagent dependent and decreases with increasing sterics around the catalyst surface.

Effect of Ga doping on the catalytic performance of Zn-ZSM-5 for CO2-assisted oxidative dehydrogenation of C2H6

Journal of CO2 Utilization
Using a low silica-to-alumina ratio NaZSM-5 zeolite as the support, a bimetallic modified catalyst, GaxZnZ5, was prepared through ion-exchange method for CO2-mediated oxidative dehydrogenation of C2H6 (CO2-ODH).
