Periodic operation in chemical reactors involves the intentional modulation of operating conditions, such as reactant concentrations, flow rates or temperatures, rather than relying on a constant ...

The nonlinear susceptibility is a measure of a material's nonlinear response to an applied electric field. It determines the strength of the nonlinear effects and is related to the crystal's symmetry ...

What do engineers see when they look at a real system or conceive a new design? They will look past the hardware and visualize the flow of energy, where it is stored, and where it is dissipated. They ...
