Hole‐transporting layers (HTLs) play a crucial role in the performance of inverted, p‐i‐n perovskite solar cells (PSCs). Chlorophylls (Chls) are naturally abundant organic photoconductors on earth, with good charge carrier mobility and appropriate Fermi energy levels that make them promising candidates for use in photovoltaic devices. However, Chls films prepared using the solution method exhibit...
Multifunctional electrocatalysts are crucial to cost‐effective electrochemical energy conversion and storage systems requiring mutual enhancement of disparate reactions. Embedding noble metal nanoparticles in 2D metal–organic frameworks (MOFs) are proposed as an effective strategy, however, the hybrids usually suffer from poor electrochemical performance and electrical conductivity in operating conditions...
Gossypol is a chemotherapeutic drug that can inhibit the anti‐apoptotic protein Bcl‐2, but the existing gossypol‐related nanocarriers cannot well solve the problem of chemotherapy resistance. Based on the observation that gossypol becomes black upon Fe3+ coordination, it is hypothesized that encasing gossypol in glyceryl monooleate (GMO) and making it coordinate cobalt ferrite will not only improve...
Effectively interfering energy metabolism in tumor cells and simultaneously activating the in vivo immune system to perform immune attacks are meaningful for tumor treatment. However, precisely targeted therapy is still a huge challenge. Herein, a mitochondrial‐targeting phototheranostic system, FE‐T nanoparticles (FE‐T NPs) are developed to damage mitochondria in tumor cells and change the tumor...
Surface‐enhanced Raman spectroscopy (SERS) is a promising technology for wearable sensors due to its fingerprint spectrum and high detection sensitivity. However, since SERS‐activity is sensitive to both the distribution of “hotspots” and excitation angle, it is profoundly challenging to develop a wearable SERS sensor with high stability under various deformations during movements. Herein, inspired...
Transparent glass with metal mesh is considered a promising strategy for high performance transparent glass heaters (TGHs). However, the realization of simple, low‐cost manufacture of high performance TGHs still faces great challenges. Here, a technique for the fabrication of high performance TGHs is proposed using liquid sacrificial substrate electric‐field‐driven (LS‐EFD) microscale 3D printing...
Transparent Glass Heaters
In article number 2107811, Xiaoyang Zhu, Xiaofeng Xu, Hongbo Lan, and co‐workers develop a fabrication method of silver mesh for transparent glass heaters (TGHs) via liquid sacrificial substrate electric‐field‐driven microscale 3D printing thick film silver paste. The fabricated TGHs exhibit excellent comprehensive performance. Furthermore, an interface evaporator is demonstrated...
NiCo2O4 nanowire array on carbon cloth (NiCo2O4/CC) is proposed as a highly active electrocatalyst for ambient nitrate (NO3−) reduction to ammonia (NH3). In 0.1 m NaOH solution with 0.1 m NaNO3, such NiCo2O4/CC achieves a high Faradic efficiency of 99.0% and a large NH3 yield up to 973.2 µmol h−1 cm−2. The superior catalytic activity of NiCo2O4 comes from its half‐metal feature and optimized adsorption...
Heterogeneous atoms substitution is an efficient method for promoting Li+ storage of transition metal oxides. Herein, a series of Fe‐substituted MnO solid solutions with different Fe contents are synthesized by a feasible solid‐phase method. The synergistic effects between heterogeneous atoms and rich vacancies are synchronously obtained, which hold distinctive electronic structures and substantial...
Native extracellular matrix (ECM) exhibits dynamic change in the ligand position. Herein, the ECM‐emulating control and real‐time monitoring of stem cell differentiation are demonstrated by ligand nanoassembly. The density of gold nanoassembly presenting cell‐adhesive Arg‐Gly‐Asp (RGD) ligand on Fe3O4 (magnetite) nanoparticle in nanostructures flexibly grafted to material is changed while keeping...
