Shape-shifting material could transform future of implantable and ingestible medical devices
Researchers led by Rice University's Yong Lin Kong have developed a soft but strong metamaterial that can be controlled remotely to rapidly transform its size and shape.

A Deep Learning Model of Lightning Stroke Density
Lightning plays a crucial role in the Earth's climate system, yet existing parameterizations for use in forecasting and earth system models show room for improvement in capturing spatial and temporal variations in its frequency. This study develops deep learning-based parameterizations of lightning stroke density using meteorological variables from the ERA and IMERG datasets. Convolutional neural networks (CNNs) with U-Net architectures are trained using World Wide Lightning Location Network (W…

Self-organized adaptive branching in frangible matter
Soft and frangible materials that remodel under flow can give rise to branched patterns shaped by material properties, boundary conditions, and the time scales of forcing. We present a general theoretical framework for emergent branching in these frangible (or threshold) materials that switch abruptly from resisting flow to permitting flow once local stresses exceed a threshold, relevant for ex- amples as varied as dielectric breakdown of insulators and the erosion of soft materials. Simulation…

Structural Phase Separation and Enhanced Superconductivity in La1.875Ba0.125CuO4 under Uniaxial Strain
Strain engineering has attracted significant attention in recent years due to its capability in tuning lattice and electronic structures of quantum materials. Using moderate uniaxial compressive strain, we induce structural phase separation in the low-temperature phase of x=1/8 La2-xBaxCuO4 (LBCO) single crystals. These structures are low temperature tetragonal (LTT), low temperature less orthorhombic (LTLO), and a plastically deformed nano-domain structure (PDNS), comprised of few-nanometer-si…

The problem of sharp notch in microstructured solids governed by dipolar gradient elasticity
In this paper, we deal with the asymptotic problem of a body of infinite extent with a notch (re-entrant corner) under remotely applied plane-strain or anti-plane shear loadings. The problem is formulated within the framework of the Toupin-Mindlin theory of dipolar gradient elasticity. This generalized continuum theory is appropriate to model the response of materials with microstructure. A linear version of the theory results by considering a linear isotropic expression for the strain-energy d…

Exploring the functional properties of diamond-like quaternary compound Li$_2$ZnGeS$_4$ for potential energy applications: A theoretical approach
It is anticipated that wide-bandgap semiconductors (WBGSs) would be useful materials for energy production and storage. A well-synthesized, yet, scarcely explored diamond-like quaternary semiconductor-Li$_2$ZnGeS$_4$ has been considered for this work. Herein, we have employed two well-known functionals GGA and mGGA within a frame-work of density functional theory (DFT). We have explored the electronic, optical, mechanical, and piezo-electromechanical properties. Our results are in qualitative a…
