Summary: In this study, LPCVD was utilized to grow MWCNTs on a Si substrate. Different thicknesses of Fe nanoparticles were coated on the Si substrate, and the surface of MWCNTs was further coated with ZnO nanoparticles to enhance the field emission properties. Various characterization techniques confirmed the growth of MWCNTs and the attachment of ZnO nanoparticles. The ZnO attached MWCNTs exhibited higher current density, lower turn-on voltage, higher field enhancement factor, better repeatability, and good stability, making them superior field emitters compared to MWCNTs and ZnO-attached MWCNTs with thicker iron layers.

Summary: Thermal energy is widely distributed and generated in nature and society, and thermocells (TECs) have become a promising technology to convert thermal energy into electricity. However, the use of noble platinum electrodes in TECs limits their widespread applications due to the scarcity and rigidity of platinum. In this study, we propose a facile method to construct flexible electrodes with optimized nanostructures, using conducting polypyrrole nanospheres decorated on a single-walled carbon nanotube network. The resulting flexible composite electrode shows superior thermoelectrochemical performance compared to the noble platinum electrode.

Summary: In this study, a CO2 sensor capable of low-temperature operation was fabricated using an open-channel-type thin-film transistor structure with a polar surface of an oxide semiconductor. The sensor showed a sensitivity 2.9 times greater than that under an inert N2 atmosphere at an operating temperature of only 150 degrees C. The results suggest that TFTs fabricated with polar surfaces of oxide semiconductors are useful for gas-sensing applications.

Summary: In this study, a defective system of V-doped Fe2O3 with Pt as a cocatalyst was used for photoelectrochemical water oxidation. The defects in the VFPt-2.5 photoanode were characterized by XPS and EPR analyses. The SEM and TEM analyses revealed that the electrodeposited V-doped alpha-Fe2O3 had a nanosized morphology with an average diameter of 12 nm and a thickness of 300 nm. Under light irradiation, the VFPt-2.5 photoanode achieved a remarkable onset potential and photocurrent density. The stability test showed that Pt helped overcome the charge recombination caused by surface states.
