Abstract: A nanozyme material and a preparation method thereof are provided. In the preparation method, Prussian blue (PB) is used to regulate the peroxidase activity of Fe,NA/CDs, and then gold nanoparticles are synthesized with Fe,NA/CDs as a reducing agent and a stabilizing agent. The nanozyme material has both a peroxidase activity and a Raman enhancement effect, which can be used for nanozyme-based surface-enhanced Raman spectroscopy (SERS). An embodiment of the present disclosure also provides a method for rapidly detection of a Pb2+ ion, which is based on a color change or an additional Raman SERS signal generation caused by nanozyme oxidation. Such sensing signals (colorimetric and SERS analysis) are derived from a catalytic oxidation reaction of ABTS or TMB, while the presence of Pb2+ specifically inhibits the oxidation, such that the rapid detection of Pb2+ can be achieved.

Abstract: Various systems and methods are presented regarding monitoring and controlling operation of a process. A visual representation of the process can be created based on a supermodel comprising models (representing one or more devices) and nodes (representing respective device variables and constraints). Further, the process can be represented by levels, wherein devices at each level can be self-aware and have onboard artificial intelligence, such that a device at any level can auto-configure itself in accordance with a requirement placed upon it. Field-level devices (IFLDs) can be smart devices which auto-configure based upon a requirement from a higher-level device. Accordingly, system awareness can be incorporated across all levels of the process enabling overall and device-specific optimization of the process.

Abstract: Based on an aramid polymer prepared, the modified aramid dope is prepared through a combination of covalent crosslinking and non-covalent crosslinking. By adjusting the amounts of a crosslinking agent and a polar polymer, an aramid film is obtained that meets the following requirements simultaneously: superior heat resistance and mechanical strength, high toughness, a simple preparation process, high stretchability, and resistance to breakage. Furthermore, the aramid film can be directly laminated with aramid paper without use of an adhesive, so that a flexible composite material in compliance with insulation class F or H is prepared through direct lamination. This application is widely applicable to motors, generators, transformers, adhesive tape, and other fields.
