Engineered Protein‐Based Ionic Conductors for Sustainable Energy Storage Applications

Advanced Materials, EarlyView.
Rational incorporation of charged residues into an engineered, self‐assembling protein scaffold yields solid‐state protein films with outstanding ionic conductivity. Salt‐doping further enhances conductivity, an effect amplified in the engineered variants. These properties enable the material integration into an efficient supercapacitor.

Physiological concentrations of bile acids down-regulate agonist induced secretion in colonic epithelial cells [PDF]

, 2009
In patients with bile acid malabsorption, high concentrations of bile acids enter the colon and stimulate Cl− and fluid secretion, thereby causing diarrhoea. However, deoxycholic acid (DCA), the predominant colonic bile acid, is normally present at lower

Combining Electrochemical Reduction with Biosynthesis for Directed Conversion of CO2 into a Library of C3 Chemicals

Advanced Science, EarlyView.
In the H‐type electrolytic cell, carbon dioxide is reduced to acetic acid via electro‐microbial catalysis. The simply processed acetic acid is further converted through biological fermentation into high‐value‐added products, including acrylic acid, L‐lactic acid, and β‐alanine.

A Single‐Enzyme Activated CRISPR‐Cas12a Nano System via Subtly Balanced dsDNA for Kinetic‐Gated UDG Detection and Spatiotemporal Cellular Imaging

Advanced Science, EarlyView.
Kinetic‐gated CRISPR–Cas12a activation enables single‐enzyme detection and spatiotemporal imaging of UDG ABSTRACT Uracil‐DNA glycosylase (UDG) is a key enzyme in base excision repair and an important biomarker for genomic stability and disease. In many reported sensing systems, uracil excision is coupled to signal generation through additional ...
