Summary: In this study, the authors demonstrate how the fast reaction rate activates charge redistribution in manganese hexacyanomanganates, which helps alleviate the strong Jahn-Teller effect of high-spin Mn(III) by solving the unequal number of electrons in e(g) orbitals. As a result, the dissolution of Mn is effectively suppressed, leading to improved long-term cyclability in an aqueous electrolyte.

Summary: The solution mixing method was used to synthesize polymer semiconductor nanoparticles (NPs) of poly(9,9-dioctylflfluorene-co-benzothiadiazole) (F8BT), which were then mixed with poly(methyl methacrylate) (PMMA) to prepare an integrated floating-gate/tunneling layer. This layer was utilized to fabricate flexible floating-gate based organic field-effect transistor non-volatile memories (F-OFET-NVMs). The microstructure of the memory devices' floating-gate/tunneling layer was found to significantly affect the device performance.

Summary: Due to the time-consuming and laborious nature of conventional methods for detecting biological genetic information, it is crucial to study high-performance DNA biosensors. In this study, an aligned Gd-doped In2O3 nanofiber with favorable carrier transport was prepared using electrospinning. The resulting aligned In2O3 nanofiber field-effect transistors (FETs) demonstrated excellent mobility (mu = 8.7 cm2/Vs), suitable threshold voltage (VTH = 0.3 V), large on/off current ratio (Ion/Ioff= 4.1 x 107), and outstanding stability when the Gd doping concentration was 0.5 mol %. The FET biosensor based on one-dimensional nanofibers has a simple structure, fast response, high sensitivity, and great potential for biosensor applications. The current variation in the FET, caused by as low as 10 nM DNA immobilized in the active layer of the aligned In1.995Gd0.005O3 nanofiber FET, becomes more pronounced with higher concentrations of immobilized DNA. The current variation is mainly attributed to the oxidation of guanine nucleotides in the DNA molecular chain. The aligned Gd-doped In2O3 nanofiber FETs exhibit high sensitivity to DNA at room temperature, providing a solution for the development of novel DNA biosensors.
