Stamping Lithography on Arbitrary Surfaces based on Self‐Assembly of Colloidal Particles

Advanced Science, EarlyView.
A new method called Stamping Lithography for three‐dimensional (3D) circuits manufacturing is proposed, which comprises a resist mask stamping process based on self‐assembly of colloidal particles and a subsequent etching process. It replaces the photoresist with self‐assembled particles and the exposure process with stamping, making it feasible to ...

Lightweight and High‐Strength Carbon Bulk Preparation Via Low‐Temperature Pressureless Sintering of Sugar‐Derived Carbon

Advanced Science, EarlyView.
The synergistic effect between crosslinked polyacrylamide and glucose brings the precursor sintering activity with better thermostability, allowing its formation of a coherent carbon structure at lower temperatures (≤ 1200 °C) under ambient pressure.

Thermal‐Stable and High‐Performance Organic Nonlinear Optical Chromophores for Advanced Electro‐Optic Modulators

Advanced Science, EarlyView.
To address the challenge of high electro‐optic (EO) activity and thermal stability, four chromophores (BHG1–BHG4) are designed. These incorporate steric hindrance groups into the aniline donor, significantly raising their glass transition temperatures and enhancing alignment stability. The neat BHG2 film achieves an exceptional EO coefficient of 304 pm

High‐Entropy Ferroelectric‐Ferroelastic Hybrid for Ultrahigh and Temperature‐Insensitive Dielectric Energy Storage

Advanced Science, EarlyView.
A high‐entropy ferroelectric‐ferroelastic hybrid perovskite material is successfully developed, in which a unique hybrid architecture, ferroelastic microdomainsembedded with randomly dispersed polar nanoregions, endows the ceramic with polar heterogeneity as well as lowered polarization hysteresis, delayed saturation polarization and enhanced breakdown
