Harnessing Phase Separation for the Development of High‐Performance Hydrogels

Advanced Science, EarlyView.
ABSTRACT Hydrogels are indispensable for the development of next‐generation bioelectronics, soft robotics, and biomedical devices, where their mechanical properties determine performance and reliability. Among strategies to enhance hydrogel mechanics, phase separation enables controlled heterogeneity resulting in gel networks that are reinforced by ...

Structure of unsteady stably stratified turbulence with mean shear.

, 2004
The statistics of unsteady turbulence with uniform stratification N (Brunt–Väisälä frequency) and shear α(=dU1/dx3) are analysed over the entire time range (00 and \it Ri>0.25 respectively, oscillatory momentum and positive and negative density fluxes ...

A Stretchable, Mechanically‐Interlocked Polyrotaxane Hydrogel for Wearable Motion and Electrophysiological Monitoring

Advanced Science, EarlyView.
A mechanically interlocked polyrotaxane hydrogel integrates sliding macrocycles within a covalent network, yielding skin‑like softness, high stretchability, robust adhesion, and stable ionic conductivity. This multifunctional interface enables simultaneous high‑fidelity monitoring of human motion and epidermal electrophysiological signals (ECG/EMG ...

Shear-wave velocity prediction in organic-rich rocks incorporating kerogen morphology and pore geometry

Frontiers in Earth Science
Conventional rock-physics models often neglect the coupled effects of kerogen morphology and pore geometry on elastic-wave propagation when estimating shear-wave velocity in organic-rich rocks. To address this limitation, this study proposes a shear-wave

Analysis of the Multicollinearity of Regression Equations of Shear Wave Velocities

Soils and Foundations, 1992
ABSTRACT The multiple regression model with parameters of N-value and depth implies a form of shear wave velocity with a specific physical meaning, but these two parameters are not independent of each other. The research introduced statistical analysis techniques of the stepwise selection, the “rule of thumb” test, and the “RSM” test to overcome the ...

The formation of shear and density layers in stably stratified trubulent flows: linear processes

, 2002
The initial evolution of the momentum and buoyancy fluxes in a freely decaying, stably stratified homogeneous turbulent flow with r.m.s. velocity u′0 and integral lengthscale l0 is calculated using a weakly inhomogeneous and unsteady form of the rapid ...

Impedance‐Matched High‐Overtone Thickness‐Shear Bulk Acoustic Resonators With Scalable Mode Volume

Advanced Science, EarlyView.
A bottom‐electrode‐free high‐overtone bulk acoustic resonator is achieved by lateral excitation of antisymmetric thickness‐shear modes on a lithium‐niobate‐on‐silicon platform. Planar electrode geometry eliminates conventional loading along the resonance path and confines acoustic energy within the electrode gap.

Prediction of Shear Wave velocity for carbonate rocks

Iraqi Journal of Chemical and Petroleum Engineering, 2015
In many oil fields only the BHC logs (borehole compensated sonic tool) are available to provide interval transit time (Δtp), the reciprocal of compressional wave velocity VP.

Experimental validation of efficient impact simulation methodologies of sandwich structures

, 2007
Aircraft design calls for weight efficient shell constructions. Composite sandwich structures satisfy this demand by the combination of two thin, stiff face sheets and an intermediate lightweight core.
