“…This indicated that the modified electrode has high selectivity as the peak current of AA and UA decreased noticeably after the addition of DA standard solution. 46,47 A recovery study was applied to verify the accuracy of the designed method by adding the DA standard solution to the urine sample. The AuNPs/PEDOT/rGO/GCE in human urine sample was investigated by standard addition technique.…”

In this research, the electrochemical method was used as a tool with the newly proposed electrode to detect dopamine (DA) in the urine sample. Gold/Poly3,4-ethylene-dioxythiophene/reduced-graphene oxide (AuNPs/PEDOT/rGO) nanocomposite material was synthesised via the facile one-pot method. The presence of Au/PEDOT on the rGO sheet was investigated by Fourier Transform Infrared (FTIR) spectrometer, Scanning Electron Microscope (SEM) and Ultraviolet-visible (UV–vis) spectroscopy. The synthesised nanocomposite material was then drop-casted on bare glassy carbon electrode (GCE) to improve the detection performance. The electrochemical behaviour of AuNPs/PEDOT/rGO/GCE was studied by Cyclic Voltammetry (CV) and Differential Pulse Voltammetry (DPV). Under optimum condition, the AuNPs/PEDOT/rGO/GCE showed linear voltammetric response in the concentration 20 to 200 nM for DA with the detection limit (LOD) and detection quantitation (LOQ) of 1.04 and 3.47 nM, respectively. This developed sensor was applied to human urine sample with good percentage recovery of 88.31%. It also exhibited good reproducibility and repeatability with relative standard error (RSD) of 9.58% and 2.7%, respectively. Hence, the proposed modified electrode offers an exceptional selectivity and high sensitivity towards the electrochemical sensing of dopamine in human samples.

The breakthrough of energy storage technology will enable energy distribution and adaptation across space‐time, which is revolutionary for the generation of energy. Optimizing the energy storage performance of polymer dielectrics remains challenging via the physical process of electrical breakdown in solid dielectrics is hard to be intuitively obtained. In this review article, the application of computational simulation technologies is summarized in energy‐storage polymer dielectrics and the effect of control variables and design structures on the material properties with an emphasis on dielectric breakdown and energy storage performance are highlighted. The prediction and evaluation of material properties by combining various data analysis methods are reviewed. Finally, the outlook and challenges are discussed based on their current developments. This article covers not only an overview of the state‐of‐the‐art advances of breakdown modeling in energy‐storage polymer dielectrics but also the prospects that provide a new knob to synthesize high energy‐storage polymer dielectrics via computational simulation and a new research paradigm.

In order to meet the requirements of practical applications, the comprehensive performance of thermally conductive high‐voltage insulating composites is worth evaluating. Guided by the particle packing theory, spherical alumina particles with different particle size distributions were compounded and filled into low‐density polyethylene (LDPE), and the thermal conductivity (TC) and mechanical breakdown of different compound systems were systematically investigated. The results show that the particle grading design of small‐particle filled composites has better comprehensive properties than that of single‐scale or large‐particle filled composites, which proves the superiority and feasibility of particle grading design. The 110–40 wt.% composite has a higher TC (0.47 W/(m K)) compared with LDPE, while maintaining excellent insulation properties (227 kV/mm) and mechanical properties (tensile strength of 10 MPa and elongation at break of 720%). Finally, studies on the application of composite materials in the field of thermal management and ice melting of steel‐core aluminum insulated wires were applied, and both studies show good prospects for the applications of Al2O3/LDPE thermal conductive high‐voltage insulation composites.
