Extended droplet theory for aging in short-ranged spin glasses and a numerical examination

, 2002
We analyze isothermal aging of a four dimensional Edwards-Anderson model in detail by Monte Carlo simulations. We analyze the data in the view of an extended version of the droplet theory proposed recently (cond-mat/0202110) which is based on the ...

Microscale Mapping of Fiber Strain and Damage in Composite Wrinkled Laminates Using Computed Tomography Assisted Wide‐Angle X‐Ray Scattering

Advanced Science, EarlyView.
This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

Semiconducting THO‐C3N Monolayers for Ultrahigh Anisotropic Carrier Mobility

Advanced Science, EarlyView.
A precise site‐specific N‐doping strategy that drives a secondary electronic transition in net W is proposed, enabling the electronic properties transition from metal to Dirac semimetal and ultimately to semiconductor. The obtained THO‐C3N‐2 and THO‐C3N‐3 semiconductors exhibit high carrier mobilities and pronounced mobility anisotropy, with THO‐C3N‐2 ...

Structural and Mechanical Dynamics of Polymer Membranes Across Multilength Scales

Advanced Science, EarlyView.
Distinct surface‐to‐bulk mechanical contrasts in polymer membranes were unveiled, highlighting the need to probe both regions to fully capture their functional behavior. By integrating in situ SAXS–WAXS with AFM‐based nanomechanics, nanodomain‐level heterogeneity and real‐time structural transformations induced by thermal and mechanical stimuli were ...

Two‐Dimensional La2CoO4 Perovskite Oxide Enabled by Phonon‐Resonance‐Driven Exfoliation for High‐Performance Gas Sensing

Advanced Science, EarlyView.
Few‐layer La2CoO4 nanosheets are produced via phonon‐resonance‐assisted cleavage of the rock‐salt layers in the Ruddlesden‐Popper structure under the 20 kHz resonance condition, enabling controlled exfoliation into ultrathin sheets. The nanosheets show improved gas‐sensing capability, delivering an 86.67% response to 1 ppm NO2 at room temperature ...

Excellent vibration isolation properties of a curved Euler beam QZS isolator: Simulation and experiment

Advances in Mechanical Engineering
In this study, a novel curved Euler beam quasi-zero stiffness (CE-QZS) isolator is proposed by limiting the displacement of the curved Euler beam to change its deformation mode, and the excellent vibration isolation properties are presented.

Rotary Electromechanical System Integrating Non‐Reciprocal Memory and Combinational Logic

Advanced Science, EarlyView.
Rotational bistability, interfaced through a conductive network with switchable contacts, unifies logic operations and mechanical memory within a rotary electromechanical system. The author demonstrates how serially coupled configurations of rotationally bistable modules enable reprogrammable sequential logic governed by mechanical state transition and
