Current environmental scenarios demand an optimum balance between the amount of energy usage and associated CO2 emissions. CO2 can serve as a carbon source and can be utilized for producing a variety of value added chemicals. A novel concept of zero CO2 emission power generation is investigated. Possible options range from adopting alternative methane-based reactions that produce energy and...

A review of the hydrate based gas separation (HBGS) process for carbon dioxide pre-combustion capture
Hydrate based gas separation (HBGS) process has been considered as a promising new/novel approach for CO2 separation from fuel and flue gas mixtures. The basis for separation is the selective partition of the CO2 component of a fuel or flue gas mixture between the solid hydrate crystal phase and the gaseous phase upon hydrate crystal formation. The advantages of employing the HBGS process for...
Photoactivatable AIE Polymer for Light Controlled Gene Delivery: Concurrent Endo-/Lysosomal Escaping and DNA Unpacking
Endo-/lysosomal escaping of gene vectors and the subsequent unpacking of nucleic acid in cytosol are two major challenges for efficient gene delivery. Herein, we report a polymeric gene delivery vector, which consists of a photosensitizer (PS) with aggregation-induced emission (AIE) characteristics and oligoethylenimine (OEI) conjugated via a reactive oxygen species (ROS) cleavable...
Phosphorus is a pollutant but is also an important nonrenewable resource. A hybrid microfiltration-forward osmosis membrane bioreactor system was designed for direct phosphorus recovery from municipal wastewater. A forward osmosis (FO) membrane and a microfiltration (MF) membrane were operated in parallel in a bioreactor for wastewater treatment. FO membrane rejects the nutrients (e.g., PO43−,...
A new catalytic system to transform free fatty acids into transportation fuels, in the absence of hydrogen gas, and other auxiliary reagents, over cheap Ni based catalyst was developed. It holds to promise the convert waste grease to diesel, for which the current technology based on transesterification reactions could not handle. The work was selected as the Journal Front Cover in Green...
