A theoretical model of a nonlinear hyperbolic metamaterial is presented in the form of a stack of subwavelength layers of linear plasmonic and nonlinear dielectric materials. A broad picture of the properties of evanescent waves(high-k modes) in this stack is investigated by plotting global transmission diagrams. The…
A nanocomposite coating was prepared with epoxy resin as film-forming agent,polysiloxane as coupling agent and with proper additives of pigments, fillers and nano silicon dioxide.The nanocomposite coating was applied on carbon steel Q235, and its corrosion performance, in comparison with a present used coating, was in…
The primary function of the peripheral nerves is to transmit signals from the spinal cord to the rest of the body,or to convey sensory information from the rest of the body to the spinal cord.In case of injury or a health disorder,this pathway can be partially or totally disrupted,resulting in pain,loss of sensation,r…
Numerical simulations of gas–liquid two-phase flow and alumina transport process in an aluminum reduction cell were conducted to investigate the effects of anode configurations on the bath flow, gas volume fraction and alumina content distributions. An Euler–Euler two-fluid model was employed coupled with a species tr…
Solidification characteristics of Ti–46Al–7Nb melts were studied by the electromagnetic levitation technique.A maximum melt undercooling up to 240 K has been achieved. When the undercooling is lower than the critical value DT* = 205 K, the alloy possesses typical hypoperitectic solidification characteristic which can…
Anisotropic CeC o4.325-xCu0.675Fex(x = 0.475-0.875) sintered magnets were prepared by traditional powder metallurgical method. Influence of ball-milling time and iron content on microstructure and magnetic properties of the CeC o4.325-xCu0.675 Fexsintered magnets were investigated. It is shown that the properties of t…
