Oxygen-Assisted Supercapacitive Swing Adsorption of Carbon Dioxide.

We report on the supercapacitive swing adsorption (SSA) of carbon dioxide at different voltage windows in the presence of oxygen using activated carbon electrodes, and deliquescent, aqueous electrolytes. The presence of O in the CO/N gas mixture results in an up to 11 times higher CO adsorption capacity with 3 M MgBr (at 0.6 V) and up to 4-5 times higher adsorption capacity with 3 M MgCl (at 1 V).

Pollutant Abatement of Nitrogen-Based Fuel Effluents over Mono- and Bimetallic Pt/Ru Catalysts.

Mono- and bimetallic alloy Pt and Ru catalysts supported on γ-AlO have been investigated for the reduction of pollutants (NO , NH, and CO) generated during the continuous combustion of an aqueous urea ammonium nitrate fuel. A Pt/Ru alloy with a Pt25/Ru75 atomic ratio has been found to have higher activity and selectivity than those of a 50/50 alloy and monometallic catalysts. Among monometallic catalysts, Ru was more selective toward N formation, whereas Pt showed a higher selectivity toward NH formation.

Host-dependent differences in abundance, composition and host range of cyanophages from the Red Sea.

Cyanobacteria coexist in the oceans with a wealth of phages that infect them. While numerous studies have investigated Synechococcus phages, much less data are available for Prochlorococcus phages. Furthermore, little is known about cyanophage composition.
