Seeking an electrochemical catalyst to accelerate the liquid‐to‐solid conversion of soluble lithium polysulfides to insoluble products is crucial to inhibit the shuttle effect in lithium–sulfur (Li–S) batteries and thus increase their practical energy density. Mn‐based mullite (SmMn2O5) is used as a model catalyst for the sulfur redox reaction to show how the design rules involving lattice matching...
The next generation of RFID will be governed by developments which have occurred in the production of printed semiconductors and in the manufacturing techniques by which RFID tags can be produced using these new materials. The paper considers all of these matters as well as protocols that are appropriate for printed tags.
With continuous development of the visual presentation technology on stage, special effect devices have occupied an important place already. In contrast to traditional mutually independent control method, we propose and realize, in this paper, an integrated-control system of stage effect devices. This system ultimately achieve the effect of unified and cooperative control. In addition, we also further...
In order to meet the requirement of cultural performance on stage design, people always make a comprehensive plan for the character or some specific scene according to the proceeding of the story line. Therefore, we should make full use of various kinds of visual elements such as stage lighting and special effect devices. In this paper, the current control method for different kinds of visual effect...
This stage manage system is designed specifically for the integrated-control console of visual-effect equipment. System architecture, functional implementation and technical solution are proposed detailedly in this paper. This system is established based on C/S framework. Data transmission between the stage management console of visual-effect equipment and the integrated-control system is implemented...
The feasibility of identifying a large number of DVD devices in stack using a UHF RFID system is investigated in this paper. The physical and electrical parameters of packaged DVD devices are introduced, and three tag labeling methods for DVD cases together with the corresponding interrogating wave patterns, named as testing schemes “1”, “2”, “3” are explored through comprehensive experiments on a...
Recently, an electromagnetic radiation decoupler with significant advantages (low profile and simple structure) was proposed for metallic item detection in UHF RFID systems. In this paper the decoupler is investigated by simulation and experiment. Based on the simulation, some new design principles, different from the original principles of the inventors, aimed at optimizing the performance of the...
Meander line dipole antennas (MDA) are useful as radio frequency identification (RFID) tag antennas because of their relatively high radiation efficiency and small size. A method has been proposed recently to obtain the resonant frequency of an MDA by calculating its inductance. According to this method, the resonant characteristics of MDA are related to their physical dimensions such as meander height,...
