Microarchitecture sculpting via phase separation programs hydrogel mechanics by creating globular, inverse globular, and spinodal structures. Spinodal architectures deliver superior toughness and energy dissipation, while ionic modulation through single polymer phase separation offers a simple, scalable route to tune mechanical properties ...

A Variational Formulation of Dissipative Quasicontinuum Methods [PDF]
Lattice systems and discrete networks with dissipative interactions are successfully employed as meso-scale models of heterogeneous solids. As the application scale generally is much larger than that of the discrete links, physically relevant simulations

De Rerum Natura: How Do Halide Perovskites Self‐Heal From Damage?
How can lead‐halide‐perovskites self‐heal after damage from light, heat, mechanical strain, or radiation? We show that reversible chemical defects underly performance losses and recovery, highlighting the roles of halide and proton migration, redox‐driven reactions, and acid‐base equilibria.

Permanent indentation characterization for low-velocity impact modelling using three-point bending test [PDF]
This paper deals with the origin of permanent indentation in composite laminates subjected to low-velocity impact. The three-point bending test is used to exhibit a non-closure of matrix crack which is assumed as a cause of permanent indentation ...

Self‐Regulating Sodium‐Ion Battery Materials: From Phase Reconstruction to Functional Activation
Self‐regulating sodium‐ion batteries hinge on programmable phase behavior in layered oxides, interphases that renew without growth, and electrolytes that steer solvation and chemistry. This review distills mechanisms into design rules that span composition, site and entropy tuning, and self‐buffering anodes, linking operando evidence to choices and ...

AI–Guided 4D Printing of Carnivorous Plants–Inspired Microneedles for Accelerated Wound Healing
This work presents an artificial intelligence (AI)‐guided 4D‐printed microneedle platform inspired by carnivorous plants for wound healing. A thermo‐responsive shape memory polymer enables body temperature–triggered self‐coiling for autonomous wound closure.

Interphase Self‐Optimization Enables Stable Magnesium Anode in Hydrogel Electrolyte
Based on a MgCl2 hydrogel electrolyte, we identify a tridentate chelant additive to construct a magnesium oxychloride interphase on Mg metal anodes. This self‐optimized interphase enables low‐resistance Mg2+ stripping/plating, resulting in much elongated cycling life of 600 h with 0.24 V nucleation overpotential.

Solitonic State in Microscopic Dynamic Failures
Onset of permanent deformation in crystalline materials under a sharp indenter tip is accompanied by nucleation and propagation of defects. By measuring the spatio-temporal strain field nearthe indenter tip during indentation tests, we demonstrate that ...

Crack Repair in Hydroxyapatite Bioceramics Using an Ultraviolet Ultrafast Laser
The study proposes an ultrafast ultraviolet laser approach to repair hidden tooth cracks, which has been preliminarily validated on HAP. Moreover, this technique aims to strengthen the native enamel structure rather than introducing a foreign filling material.
