Purification of Waste-Generated Biogas Mixtures Using Covalent Organic Framework's High CO Selectivity.

Development of crystalline porous materials for selective CO adsorption and storage is in high demand to boost the carbon capture and storage (CCS) technology. In this regard, we have developed a β-keto enamine-based covalent organic framework () via the Schiff base polycondensation technique. The as-synthesized exhibited excellent thermal and chemical stability along with a very high surface area (1258 m g) and a high CO adsorption capacity (3.

Magnetite-Bacillus subtilis synergy on the metabolic selection of products in electrofermentation system.

The study examines the role of magnetite (1-150 mg/L) at the interface of Bacillus subtilis-electrode under poised-condition (-0.2 V) for product-formation and catalytic-conduct with the relative-gene-expression encoding lactate dehydrogenase (lctE), pyruvate dehydrogenase (pdhA), acetate kinase (ackA), pyruvate carboxylase (pycA), and NADH dehydrogenase (ndh). The magnetite load of 25 mg/L showed positive influence on acidogenesis resulting in H production of 264.

Metabolic flux of Bacillus subtilis under poised potential in electrofermentation system: Gene expression vs product formation.

The role of poised (negative/positive) potential (0.2/0.4/0.
