Fluoro‐substituted aromatic alkylammonium spacer cations are found effective to improve the performance of quasi‐2D perovskite light‐emitting diodes (PeLEDs). The fluorine substitution is generally attributed to the defect passivation, quantum well width control, and energy level adjustments. However, the substituted cations can also affect the crystallization process but is not thoroughly studied...
Femtosecond lasers enable flexible and thermal‐damage‐free ablation of solid materials and are expected to play a critical role in high‐precision cutting, drilling, and shaping of electronic chips, display panels, and industrial parts. Although the potential applications are theoretically predicted, true 3D nano‐sculpturing of solids such as glasses and crystals, has not yet been demonstrated, owing...
As an important multiferroic material, pure and low‐dimensional phase‐stable bismuth ferrite has wide applications. Herein, one‐pot hydrothermal method was used to synthesize bismuth ferrite. Almost pure Bi2Fe4O9, BiFeO3, and their mixture were successfully obtained by controlling the KOH concentration in the hydrothermal solutions. The as‐prepared Bi2Fe4O9 products were crystalline with Pbam space...
Hepatotoxicity is a key concern in the clinical translation of nanotherapeutics because preclinical studies have consistently shown that nanotherapeutics accumulates extensively in the liver. However, clinical‐stage nanotherapeutics have not shown increased hepatotoxicity. Factors that can contribute to the hepatotoxicity of nanotherapeutics beyond the intrinsic hepatotoxicity of nanoparticles (NPs)...
The relevance of personalized medicine has inspired research for individually concerted diagnosis and therapy. Numerous efforts are devoted to designing drug particulates with capabilities of tumor penetrating and subcellular trafficking to concurrently discharge theranostics in response to multistimulations. In this study, a bioinspired particulate, formulated with whole components of native high‐density...
In article number 1703110, Jianping Zhou, Yang Ding, and co‐workers introduce a bioinspired particulate formulated with whole components of native HDLs and decorated with tumor‐penetrating peptide iRGD. This proposal of penetrated HDLs (pHDLs) shares artificially endowed functions, leading to higher tumor accumulation and enhanced cellular uptake, burst intracellular drug release, and precision chemo‐phototherapy...
Transparent and flexible materials are desired for the construction of photoelectric multifunctional integrated devices and portable electronics. Herein, 2H‐SiC nanowires are assembled into a flexible, transparent, self‐standing nanowire fabric (FTS‐NWsF). The as‐synthesized ultralong nanowires form high‐quality crystals with a few stacking faults. The optical transmission spectra reveal that FTS‐NWsF...
