Dynamic Covalent Networks of Molecular Clusters for Hard and Impact‐Resistant Glass with Feasible Processability

Advanced Science, EarlyView.
Molecular granular material glass is fabricated by crosslinking sub‐nm POSS clusters with dynamic borate ester bonding while the materials combine high transparency, modulus, and hardness with superior impact resistance and (re)processability, offering a promising strategy for creating robust yet highly processable organic glasses.

Annealing‐Induced Plasticity and Strengthening in Metallic Glasses

Advanced Science, EarlyView.
This work challenges the dogma that annealing inevitably embrittles metallic glasses. We demonstrate that sub‐Tg annealing, guided by positive mixing enthalpy and constrained kinetics, can drive a self‐organized compositional fluctuation that creates an interface‐free heterogeneous structure.

Electrolyte‐Dependent Sodium Plating for Anode‐Free Na‐Ion Batteries Studied by Operando Optical Microscopy

Advanced Science, EarlyView.
Anode‐free sodium‐ion batteries are examined using carbonate‐, glyme‐, and localized high‐concentration electrolytes. Distinct sodium plating morphologies are identified by operando optical microscopy, revealing uniform crystalline deposition for glyme‐based systems.

Stimulus‐Induced Self‐Reinforcement in Supramolecular Bamboo Plastics toward Mechanical Robustness and Programmable Shapeability

Advanced Science, EarlyView.
A self‐reinforcement strategy is reported for the fabrication of bamboo plastics utilizing ethanol to induce the supramolecular network reconstruction of cellulose and polyacrylamide molecules. These bamboo plastics exhibit high mechanical strength, excellent thermal stability, resistance to low temperatures, and controllable shapeability.

Molecularly Bridged Heterointerface Engineering: Designing Transparent, Wear‐Resistant, Hard yet Flexible Optoelectronic Protective Film

Advanced Science, EarlyView.
A molecular‐bridging heterogeneous interface engineering strategy is introduced to combine a polyhedral oligomeric silsesquioxane (POSS)‐based hard coating with a colorless polyimide (CPI)‐based flexible layer. The robust heterogeneous interface endows the integrated system with the superior properties of both layers and their synergistic ...

The role of adhesion in contact mechanics

, 2018
Adhesive [e.g. van der Waals] forces were not generally taken into account in contact mechanics until 1971, when Johnson, Kendall and Roberts (JKR) generalized Hertz' solution for an elastic sphere using an energetic argument which we now recognize to be

In Situ Electrostatic Charge‐Assisted Wetting for Enhancing Interfacial Strength of Printed Electronics

Advanced Electronic Materials, EarlyView.
This study introduces an in situ electrostatic charge‐assisted wetting method to enhance the interfacial strength of aerosol jet printing. By depositing negative charges on the substrate, the technique improves ink wetting and interfacial properties, achieving up to 85.6% higher interfacial shear strength.

Unraveling Failure Mechanism of Indium Anodes in all‐Solid‐State Batteries

Advanced Energy Materials, EarlyView.
In anode has been widely used in labs due to its stability. However, it still suffers failure at high current density and areal capacity. This work demonstrates the failure mechanism of In anode and propose protective layer by atomic layer deposition could effectively enhance the performance.
