This work focusses on developing a hybrid enzyme biofuel cell‐based self‐powered biosensor with appreciable stability and durability using murine leukemia fusion gene fragments (tDNA) as a model analyte. The cell consists of a Ti3C2Tx/multiwalled carbon nanotube/gold nanoparticle/glucose oxidase bioanode and a Zn/Co‐modified carbon nanotube cathode. The bioanode uniquely exhibits strong electron transfer...
As primary feedstocks in the petrochemical industry, light olefins such as ethylene and propylene are mainly obtained from steam cracking of naphtha and short chain alkanes (ethane and propane). Due to their similar physical properties, the separations of olefins and paraffins—pivotal processes to meet the olefin purity requirement of downstream processing—are typically performed by highly energy‐intensive...
In article number 1704169, Dan Zhao and co‐workers propose a method to prepare hierarchical interconnected carbon networks with ultrahigh pore volume from NaCl/ZIF‐8 composites. The carbon networks exhibit outstanding activity, kinetics, and stability towards catalyzing the oxygen reduction reaction. They can be further integrated into cathodes of Zn–air batteries to achieve a triple life‐hour compared...
The oxygen reduction reaction (ORR) is under intense research due to its significance in energy storage and conversion processes. Recent studies show that interconnected and hierarchically porous structures can further enhance ORR kinetics as well as catalyst durability, but their preparation can be quite time and/or chemical consuming. Here, a simple approach is reported to prepare such complex structures...
Electrochemical energy conversion and storage devices such as fuel cells and metal–air batteries have been extensively studied in recent decades for their excellent conversion efficiency, high energy capacity, and low environmental impact. However, sluggish kinetics of the oxygen‐related reactions at air cathodes, i.e., oxygen reduction reaction (ORR) and oxygen evolution reaction (OER), are still...
An efficient strategy to investigate the window pore size of the silica shell generated by the Stöber method is achieved by the unique aggregation‐induced emission (AIE) property of Au(I)‐thiolate complexes, as presented by J. Xie and co‐workers on page 6537. The window size of silica shell is determined by screening the hydrated diameters of the probing metal ions, which can permeate through the...
An efficient method to investigate the window size of the silica shell generated via the classical Stöber method is reported by making use of the unique aggregation‐induced emission property of Au(I)‐thiolate complexes, which can precisely probe the porosity of the silica shell in Au(I)‐thiolate@SiO2 nanoparticles.
