A simple two-step aqueous method was employed to grow MgO nanostructures on ZnO/sapphire at low temperature. The obtained thin MgO nanostructures were uniformly distributed on the surface of ZnO layer and showed the sheet-like structures. Meanwhile, an ultraviolet (UV) photodetector based on ITO/MgO/ZnO structures was fabricated by simple way. The obtained UV detector showed excellent UV sensing properties. This novel method will greatly facilitate fabrication of large-scale metal-insulator-semiconductor with relatively low cost at remarkably low temperature.

Hybrid Aerogel

Carbon materials are generally employed as supercapacitor electrodes due to their low- cost, high-chemical stability and environmental friendliness. However, the design of carbon structures with large surface area and controllable porous structure remains a daunt challenge. In this work, a three-dimensional (3D) hybrid aerogel with different contents of MoS2 nanosheets in 3D graphene aerogel (MoS2-GA) was synthesized through a facial hydrothermal process. The influences of MoS2 content on microstructure and subsequently on electrochemical properties of MoS2-GA are systematically investigated and an optimized mass ratio with MoS2: GA of 1:2 is chosen to achieve high mechanical robustness and outstanding electrochemical performance in the hybrid structure. Due to the large specific surface area, porous structure and continuous charge transfer network, such MoS2-GA electrodes exhibit high specific capacitance, good rate capability and excellent cyclic stability, showing great potential in large-scale and low-cost fabrication of high-performance supercapacitors.

Iron oxide (Fe3O4) nanoparticles as one of the most important nanomaterials are suitable for many applications. Monodisperse magnetic Fe3O4 nanoparticles were synthesized by the thermal decomposition of the iron oleate precursor in octadecene (ODE). The iron oleate complex was prepared by reaction between sodium oleic and FeCl3·6H2O at low temperature. The Fe3O4 nanoparticles were transferred from organic solvent into water by amphiphilic copolymer. The aqueous dispersion of Fe3O4 nanoparticles was stable in water and physiological buffers. This method with low cost can be used to prepare large scale of aqueous dispersion of Fe3O4 nanoparticles.

Heating Technology

A novel method was developed to produce AlV55 alloy through reducing impurities content and component segregation with electrode assisted heating technology. This new process synergistically integrates a few low-cost process techniques, including granulation, mixing, and electro-heating to produce AlV55 alloy. During the heating process, the CaO is used as an additive in the raw materials. The uniform of AlV55 alloy composition and low impurities content are effectively controlled by this process. The analysis results show that Si (0.13 wt%), Fe (0.22 wt%), N (0.007 wt%), C (0.078 wt%), and O (0.051 wt%) impurities in the AlV55 products were reduced, which met the commercial standard (TS/T 579-2014), and V content ranged from 57.5 to 58.5 wt% when the Al/V2O5 mass ratio was 0.94:1. This method can realize the controllability of the reaction process and is suitable for large-scale industrial production.

AbstractThe elimination of conventional peripheral LSI (large-scale integration) drivers is considered essential to the development of future low-cost, energy-efficient, lightweight, and thin displays. System-on-glass (SOG) displays are a type of display with various functional circuits integrated on a glass substrate. Low-temperature polycrystalline silicon (LTPS) thin-film transistors (TFTs) make the integration of circuits possible because they can be assembled into complex, high-current driver circuits. Furthermore, LTPS TFTs are attracting attention for driving organic light-emitting devices (OLEDs). This article introduces present and future LTPS TFT technologies for SOG displays.

AbstractA gas-mediated fabrication of centimeter-scale two-dimensional (2D) semiconductors and ultraviolet photodetector by a liquid metal-based printing was reported. Various large-scale 2D materials (Ga2O3, In2O3, SnO) were demonstrated to be directly printed at ambient air on different substrates. Such printing represents a generic, fast, clean, and scalable technique to quickly manufacture 2D semiconductors. The electrical properties were explored to quantify the printed 2D films, which were somewhat deficient in previous studies. In particular, to explore and facilitate the advantages of this 2D semiconductor in functional electronic applications, strategies for realizing fully printed Ga2O3/Si heterojunction photodetector via low-temperature and low-cost processes were developed. The device exhibits excellent sensibility and rapid photoresponse times. This work offers feasible way to develop high-performance ultraviolet photodetector for mass production. It also suggests a promising direction for making large-scale 2D photoelectronic and electronic systems and is expected to be extensively useful in the coming time.
