Flow Control Using Traveling Waves [PDF]
, 2022 Flow separation is the detachment of boundary layer from a surface, which is associated with aerodynamic loss. In this work, the feasibility of controlling flow separation by backward (toward downstream) traveling waves is studied using large-eddy ...

Nonlinear Waves in Rods and Beams of Power-Law Materials
Journal of Applied Mathematics, 2017 Some novel traveling waves and special solutions to the 1D nonlinear dynamic equations of rod and beam of power-law materials are found in closed forms. The traveling solutions represent waves of high elevation that propagates without change of forms in ...

Red‐Sensitive Photopolymerizable Glass for Fabrication of Holographic Optical Elements
Advanced Optical Materials, EarlyView.This study presents a novel photopolymerizable glass capable of optical patterning using red‐wavelength laser exposure. Red‐light sensitivity was achieved through the incorporation of a photoinitiating system composed of methylene blue (MB) and N‐phenylglycine (NPG).

Advanced Optical Materials, EarlyView.The particle with high surface hydrophilicity exhibits strong thermophoretic attraction, as its dense hydration layer enhances the role of interfacial water molecules in determining thermophoretic mobility over other ionic effects. This finding elucidates the mechanism underlying the robust thermophoretic accumulation of Escherichia coli in high ...

On–Off Switchable Micromotors for Use in Steerable Microvehicles
Advanced Robotics Research, EarlyView.Electrically controllable micromotors and microvehicles are developed by tuning the diffusion of the fuel. Self‐propelled micromotors using bubble propulsion show great promise for miniaturized devices with multiuse purposes such as cargo delivery and sensing. However, there is currently no method to electrically switch the micromotors on or off. Here,

Traveling waves and shock waves
Discrete and Continuous Dynamical Systems, 2004 Traveling waves and shock waves are physically important solutions of partial differential equations. Papers in this special issue address two aspects of the theory of traveling waves and shock waves: (1) the linearized stability of traveling waves and (2) the Dafermos regularization of a system of conservation laws.
