Inkjet-printed structural color patterns have attracted great attention in recent years because of their broadly promising applications. However, the are usually fabricated on pretreated plastic substrates. Herein a convenient inkjet printing method was developed to fabricate large-scale computer-designed photo paper without any treatment using inks containing monodisperse CdS spheres. By this strategy, not only were single-color and multicolor successfully obtained, but also invisible...
This work reports an efficient melt compression method for fabricating robust CdS composite photonic crystal films with vivid and mechanically responsive structural colors that can be tailored recombined into multicolor patterns facilely.
Photonic crystals (PCs) have long been considered effective for tuning upconversion luminescence due to their photonic band gap (PBG) and the redistribution of density optical states (DOS). Although emission intensity can be changed obviously by PC effect, rarely an obvious lifetime change consistent with theory is observed low refractive index PS or SiO2 spheres in commonly used PCs. Herein, CdS/NaYF4:Yb3+,Er3+ composite PCs a high contrast are fabricated one step nanoparticles filled...
Supramolecular co-assembly can modulate the architecture of molecular assemblies, thereby influencing their electromechanical properties. However, relationship between supramolecular packing and response co-assemblies remains largely unexplored, posing a challenge in designing high-performance bioinspired piezoelectric materials. Herein, we combined experiments theoretical calculations to systematically explore regulation properties cyclic l-aspartyl-l-aspartyl (cyclo-DD (LL))-based...

Abstract Transition metal chalcogenides (TMCs) belongs to the most promising class of materials with unique properties and widespread applications. Coupling carbon allows further enhancement specific performance TMCs by mitigating their intrinsic deficiencies. However, synthesis a wide variety TMCs/carbon composites universal strategy especially in scalable manner remains challenging. In this work, utilizing gas‐liquid interfaces viscous gel precursors, an “all‐in‐one” blowing is proposed...

Reactive oxygen species (ROS) - induced oxidative stress damage of dopaminergic neurons is the principal etiology Parkinson's disease (PD). While most nanoenzymes can catalyze breakdown ROS present in brain, they cannot eradicate source production attributed to damaged mitochondria. Herein, we introduce a Co-doped Prussian blue (PB/Co) nanozyme that demonstrates multi-enzyme-like coordinated activity for scavenging and triggers mitophagy remove To further augment brain entry efficiency PB/Co...
