This paper reviews the manufacturing difficulties of decimal quantum resistor arrays and their applications and prospects in electrical metrology standardization.By analyzing the core principles of the quantum Hall effect, the advantages and differences of gallium arsenide (GaAs) and graphene ION in quantum resistor arrays are discussed.This paper
With the advancement in imaging technologies for scanning and printing, production of copyright banknotes has become cheaper, easier, and more common.The proliferation of copyright banknotes causes loss to banks, traders, and individuals involved in financial transactions.Hence, it is inevitably needed Scene Setters that efficient and reliable tech
[Objectives] During the discharging of ship-used steam power,steam jet condensation was a common physical process.In order to fully grasp the fundamental physical phenomena within steam submerged jet and condensation under open space,CFD simulation with Mixture multiphase model was carried out.[Methods] With the experimental results,heat transfer m
Solutions of surfactants exhibit remarkable features, such as a tunable amphiphilic character, which can further be varied for ionic surfactants through variations in their Coulombic interactions.These properties are very useful in many industrial applications such as in extraction, purification, and formulation processes, as detergents, wetting ag
