Advanced Functional Materials, EarlyView.Resonant standing waves generate large‐area lattices of liquid‐crystal topological defects that are permanently encoded into polymer coatings by photopolymerization. The preserved director architecture produces thermally reconfigurable surface topographies while maintaining programmable optical functionality, demonstrating a scalable strategy for ...

Acoustic impulse responses for nonuniform media [PDF]
, 1992 The acoustic impulse responses of a family of nonuniform lossless one-dimensional media are determined. The nonuniform portions of the media are confined to layers of either finite or infinite thicknesses. The acoustic impedances of the nonuniform layers

Advanced Functional Materials, EarlyView.A trimodal anode architecture spatially regulates silicon clusters within confined interstitial environments formed by graphite and contorted hexabenzocoronene. This confinement suppresses silicon aggregation and localized stress while enabling efficient Li‐ion transport, achieving high‐capacity, stable lithium‐ion batteries.

Algorithms for Spectral Analysis of Irregularly Sampled Time Series [PDF]
In this paper, we present a spectral analysis method based upon least square approximation. Our method deals with nonuniform sampling. It provides meaningful phase information that varies in a predictable way as the samples are shifted in time.
