3D‐Ridge Stocked Layers of Nitrogen‐Doped Mesoporous Carbon Nanosheets for Ultrasensitive Monitoring of Dopamine Released from PC12 Cells under K+ Stimulation

“…The electrochemical activity of the NMCS/GCE was investigated using cyclic voltammetry (CV) in 10 mL of 0.1 m KCl containing 1 × 10 −3 m [Fe(CN) 6 ] 3− in the potential range of −0.2 to 0.7 V (vs Ag/AgCl), and at a scan rate of 100 mV s −1 . The [Fe(CN) 6 ] 3− was used as a redox probe to check the key factors affecting the charge transfer along the designated electrode surfaces including charge transfer properties, electrocatalytic activity, and surface chemistry (Figure S2A, Supporting Information) . Results show that the efficient electron transfer activity of the NMCS/GCE is higher than that of bare GCE.…”

“…Several analytical techniques have been used for DA detection, such as chromatography, fluorimetry, rapid liquid chromatography/tandem mass spectrometry (LC‐MS/MS), chemiluminescence, and plasmonic probing . Although these techniques show high sensitivity and selectivity toward DA, but they associated with complex and time‐consuming protocol, specific procedures, and expensive tools for biosensing preparations . Thus, the development of simple and inexpensive analytical methods for selective and sensitive detection of DA is of particular interest.…”

“…Thus, the development of simple and inexpensive analytical methods for selective and sensitive detection of DA is of particular interest. The electrochemical method is a great approach for DA sensing because of its short time delay production, high sensitivity and selectivity, easy handling, and applicability in vitro/in vivo, and an inexpensive analytical technique . Selective detection of DA in biological and physiological fluids is an important issue because of the low concentration of DA compared with other coexisting molecules such as ascorbic acid (AA) and uric acid (UA) .…”

Theoretical and Experimental Sets of Choice Anode/Cathode Architectonics for High-Performance Full-Scale LIB Built-up Models

“…4e and S16. The equivalent circuit comprises an electrolyte resistance (Ohmic resistance R s , which refers to the intercept impedance on the real axis and corresponds to solution resistance), charge transfer resistance (R ct , which results from the electrochemical interaction at the electrode/electrolyte interface and particle/particle contact), constant phase element, and Warburg impedance of the Li + ion diffusion into the electrode (W f ; which is related to the low-frequency region of the straight line) [25,[44][45][46][47]. The semicircular arc at the highest frequency range is relative to the R ct value, which is approximately equal to the numerical value of the diameter of the semicircle on the Z real axis.…”

HMT-Controlled Synthesis of Mesoporous NiO Hierarchical Nanostructures and Their Catalytic Role towards the Thermal Decomposition of Ammonium Perchlorate

“…Accordingly, these materials are widely applied in many important fields. Among them, nickel oxide (NiO) is an important semiconductor functional material [2], which is widely used in lithium ion batteries [3], electrocatalysis [4], thermal catalysis [5], gas sensor [6], electrochemistry [7,8], optical sensor [9] and biosensors [10][11][12][13][14] fields. Therefore, the preparation of various mesoporous NiO nanomaterials has become a research hotspot.…”
