Ion‐Reconfigurable “N”‐Shaped Antiambipolar Behavior in Organic Electrochemical Transistors

Advanced Materials, EarlyView.
A unique N‐shaped negative differential transconductance (NDT) characteristics is demonstrated in single‐polymer organic electrochemical transistors through a sequential doping–redox–doping process driven by iodide ions. This redox‐driven mechanism enables low‐voltage, ion‐controlled reconfigurability and tunable current modulation, allowing seamless ...

The cytoplasmic synthesis and coupled membrane translocation of eukaryotic polyphosphate by signal-activated VTC complex

Nature Communications, 2023
The VTC complex generate eukaryotic polyphosphate (polyP). Authors here reveal how the signal-activated VTC synthesize cytosolic polyP and transport polyP across vacuolar membrane into the lumen, by using cryo-EM, in-cell NMR, and smFRET analyses.

High‐Performance Ambipolar Organic Electrochemical Transistors Based on Diketopyrrolopyrrole‐Dialkoxybithiazole Conjugated Polymers for Single‐component Inverters

Advanced Science, EarlyView.
Two donor‐acceptor conjugated polymers, incorporating diketopyrrolopyrrole (DPP) and dialkoxybithiazole (2Tz) units with ethylene glycol (EG) side chains, exhibit relatively balanced ambipolar organic electrochemical transistor (OECT) performance. This ambipolarity enables the realization of single‐component complementary inverters capable of ternary ...

Synergistic Effects of Additive Engineering in Enhancing the Performance of Sn–Pb Perovskite Thin‐Film Transistors and Derived Logic Circuits

Advanced Science, EarlyView.
An additive engineering strategy employing 4,8‐dihydrobenzo[1,2‐b:4,5‐b′]dithiophen‐4,8‐dione (BDTD) is utilized to passivate bulk defects, regulate crystallization dynamics, and suppress Sn4+ formation in Sn–Pb perovskite thin‐film transistors. The incorporation of BDTD yields a substantial enhancement in electrical performance, increasing the hole ...
