Localization Phenomena in Mistuned Assemblies with Cyclic Symmetry Part II: Forced Vibrations [PDF]
, 1988 The effects of disorder on the forced response of nearly periodic structures with cyclic symmetry are investigated. The force model adopted here is relevant to blade assemblies.

Wood Cellulosic Membrane With Abundant Nanochannels for Stabilizing Aqueous Zn‐Ion Batteries
Advanced Functional Materials, EarlyView.A wood‐derived cellulosic membrane separator is developed to suppress dendrite growth in aqueous zinc‐ion batteries. Its aligned nanochannels and hydroxyl‐rich surfaces enable uniform Zn2+ flux, water immobilization, and interfacial stabilization. Zn||Zn cells achieve 1920 h of cycling, Zn||Cu cells maintain 99.5% Coulombic efficiency over 1000 cycles,

Dynamics of a Vertical Unbalanced Gas Centrifuge Supported by Magnetic Bearings
Engineered ScienceThe gas centrifuge is modeled as a rigid rotor supported by two magnetic bearings with eight-pole structures. To describe the system dynamics, the coupled nonlinear ordinary differential equations (ODE) of the second order are derived, to solve which the

Advanced Functional Materials, EarlyView.This study addresses silicon anode degradation using an engineered nSi/Gr/C dual‐carbon matrix. By restricting SEI infiltration, the architecture redirects silicon agglomeration into a beneficial structural self‐adaptive activation. During cycling, silicon nanoparticles self‐organize into a resilient nanoporous sponge. This dynamic network accommodates

Free and Forced Vibrations of Elastically Connected Structures
Advances in Acoustics and Vibration, 2010 A general theory for the free and forced responses of n elastically connected parallel structures is developed. It is shown that if the stiffness operator for an individual structure is self‐adjoint with respect to an inner product defined for Ck[0, 1], then the stiffness operator for the set of elastically connected structures is self‐adjoint with ...

Advanced Functional Materials, EarlyView.A Ti3C2@TiO2 heterostructure has been successfully fabricated by an in situ oxidation approach. The as‐fabricated Ti3C2@TiO2‐based photodetector exhibits narrow‐spectrum response with excellent stability. It also realizes sensitive Cr(VI) detection in a large concentration range of 10−12–10−6 M with an ultra‐low detection limit of 7.6 × 10−12 M ...
