TL;DR: In this article, the authors synthesized perpendicular SiOx nanowire arrays on Si substrates and investigated them using scanning electron microscopy and energy-dispersive spectroscopy.
Abstract: We have synthesized perpendicular SiOx nanowire (NW) arrays on Si substrates and investigated them using scanning electron microscopy. Transmission electron microscopy and energy-dispersive spectroscopy have been used to investigate the single NW structure. A near-infrared emission at 700 nm is observed. In/SiOx NW and In/SiOx thin film (TF) contacts exhibit Schottky behavior. The SiOx NW-based devices show six-fold improvements in photodetection efficiency in white-light illumination, compared to SiOx TF-based devices under reverse bias condition.

TL;DR: Progress in the research and development of carbon nanomaterials during the past twenty years or so for advanced energy conversion and storage is reviewed, along with some discussions on challenges and perspectives in this exciting field.
Abstract: It is estimated that the world will need to double its energy supply by 2050. Nanotechnology has opened up new frontiers in materials science and engineering to meet this challenge by creating new materials, particularly carbon nanomaterials, for efficient energy conversion and storage. Comparing to conventional energy materials, carbon nanomaterials possess unique size-/surface-dependent (e.g., morphological, electrical, optical, and mechanical) properties useful for enhancing the energy-conversion and storage performances. During the past 25 years or so, therefore, considerable efforts have been made to utilize the unique properties of carbon nanomaterials, including fullerenes, carbon nanotubes, and graphene, as energy materials, and tremendous progress has been achieved in developing high-performance energy conversion (e.g., solar cells and fuel cells) and storage (e.g., supercapacitors and batteries) devices. This article reviews progress in the research and development of carbon nanomaterials during the past twenty years or so for advanced energy conversion and storage, along with some discussions on challenges and perspectives in this exciting field.

TL;DR: A hierarchical architecture of the smart factory was proposed first, and then the key technologies were analyzed from the aspects of the physical resource layer, the network layer, and the data application layer, which showed that the overall equipment effectiveness of the equipment is significantly improved.
Abstract: Due to the current structure of digital factory, it is necessary to build the smart factory to upgrade the manufacturing industry. Smart factory adopts the combination of physical technology and cyber technology and deeply integrates previously independent discrete systems making the involved technologies more complex and precise than they are now. In this paper, a hierarchical architecture of the smart factory was proposed first, and then the key technologies were analyzed from the aspects of the physical resource layer, the network layer, and the data application layer. In addition, we discussed the major issues and potential solutions to key emerging technologies, such as Internet of Things (IoT), big data, and cloud computing, which are embedded in the manufacturing process. Finally, a candy packing line was used to verify the key technologies of smart factory, which showed that the overall equipment effectiveness of the equipment is significantly improved.
