Here, we firstly demonstrate that the intramolecular electron transfer within signle enzyme molecule is an important alternative pathway which can be harnessed to generate electricity. By decoupling the redox reactions within a single type of enzyme (e.g., Trametes versicolor laccase), we harvested electricity efficiently from unconventional fuels...

The presence of the micro-pollutants in the aqueous environment has become a major environmental challenge. The enzymatic membrane reactor (EMR) provides a promising approach to tackle this problem through benign enzymatic biodegradation, and the fabrication of highly efficient enzymatic membrane is the key to this process. By using a facile carbon...

Enzymatic treatment can effectively degrade recalcitrant micro-pollutants in wastewater. However, its industrial application is constrained by the high cost of the purified enzyme preparations. This work introduces a novel technique to directly immobilize the in-house crude enzyme extracts (from P. ostreatus) onto the functionalized TiO2 nanopartic...

Understanding the impact of configuration selection of industrial-scale membrane distillation (MD) is critical for a productive and energy-efficient operation of this emerging process for desalination. However, it is rarely considered even as new high flux membranes and wider applications are developed. In this context, three open-source simulators...

The management of brackish groundwater concentrates remains as a problem from the desalination of brackish groundwater. This study accessed the feasibility of various fouling mitigation techniques during the treatment of brackish groundwater concentrates at a 4-fold concentration factor for the purpose further volume reduction of wastewater. The st...

Nitrate contamination of water resources due to excessive use of nitrogen-based fertilizers has become a global health issue. In this work, a recyclable and environmentally sensitive magnetic Fe2O3/PES (Polyethersulfone) nanocomposite asymmetric membrane like capsules (NAMCs) were prepared such that release nitrate in a controlled manner. Different...

Herein, we demonstrate that the intramolecular electron transfer within a single enzyme molecule is an important alternative pathway that can be harnessed to generate electricity. By decoupling the redox reactions within a single type of enzyme (for example, Trametes versicolor laccase), we harvested electricity efficiently from unconventional fuel...

High efficient enzyme immobilization on carbon based conductive supports could provide wide applications in energy and environmental science. Here, we synthesized a 3D flower-like structured self-assembly hybrid nanocomposite with copper phosphate, laccase, graphite oxide (GO) and carbon nanotubes (CNTs) via a facile one-pot strategy under mild con...

A novel hydrophilic-superhydrophobic biocatalytic membrane was developed for CO2 capture with a gas-liquid membrane contactor. This “Janus” membrane contains a layer of hydrophilic carbon nanotubes (CNTs) coated on a fluorosilane treated superhydrophobic membrane support. The carbonic anhydrase (CA) was then immobilized on the hydrophilic CNTs side...
