Steric Coordination Modulated Iodine Chemistry With Four‐Electron Conversion for Zinc‐Iodine Batteries

Advanced Materials, EarlyView.
A dual‐additive electrolyte strategy is developed to address the hydrolysis of I+ in the aqueous electrolytes. The steric‐hindrance effect of TES− effectively shields I+ from nucleophilic attacks by hydroxyl groups, facilitating the reversible I−/I0/I+ conversion with four‐electron transfer.

Electrical Capacitance Tomography With Differential Sensor

IEEE Sensors Journal, 2015
In electrical capacitance tomography, capacitance changes are used to determine the permittivity distribution in the imaging area. However, the changes are small compared to the standing capacitances, e.g. usually in the order of 10~30%. For a single channel capacitance sensor, a differential configuration having a redundant pair of electrodes can be ...

Intimate Interaction Between Nucleic Acid and Conjugated Polymers in Organic Electrochemical Transistors Enables Ultrasensitive Biomarker Detection

Advanced Materials, EarlyView.
The intimate interaction between negatively charged RNA molecules and conjugated polymers in organic electrochemical transistors (OECTs) in aqueous electrolytes is investigated. It demonstrates that RNA binding reduces the volumetric capacitance of the polymer channel, enabling the development of an ultrasensitive biosensing platform capable of ...
