Normally, only noncentrosymmetric structure of the materials can potentially be piezoelectric. Thus, it is limited in the field of piezoelectricity for the centrosymmetric structure of the material. In this work, the performance of piezoelectricity is successfully achieved from centrosymmetric SrFeO3‐x by modulating oxygen vacancies, which have a surface piezoelectric potential up to 93 mV by using...
As a remarkable structure, 2D magnetic heterojunctions have attracted researchers’ attention owing to their controlled manipulation in the electronic device. However, successful fabrication as well as modulation of their structure and compound remain challenging. Herein, a novel method is designed to obtain a CoCl2/Co3O4 heterojunction on Si/SiO2 substrate with the assistance of supercritical CO2...
Age‐related macular degeneration (AMD), especially wet AMD with choroidal neovascularization (CNV), commonly causes blindness in older patients and disruption of the choroid followed by second‐wave injuries, including chronic inflammation, oxidative stress, and excessive matrix metalloproteinase 9 (MMP9) expression. Increased macrophage infiltrate in parallel with microglial activation and MMP9 overexpression...
Exploring antibacterial nanomaterials with excellent catalytic antibacterial properties has always been a hot research topic. However, the construction of nanomaterials with robust antibacterial activity at the atomic level remains a great challenge. Here a fully‐exposed Pd cluster atomically‐dispersed on nanodiamond‐graphene (Pdn/ND@G) with excellent catalytic antibacterial properties is reported...
T cell exhaustion caused by mitochondrial dysfunction is the major obstacle of T cells‐based cancer immunotherapy. Besides exhausted T cells, the insufficient major histocompatibility complex class I (MHC I) on tumor cells leads to inefficient T cell recognition of tumor cells, compromising therapeutic efficacy. Therapeutic platform to regulate T cell exhaustion and MHC I expression for boosting T...
Developing intrinsically stretchable organic solar cells (OSCs) with excellent mechanical robustness and long‐term operation stability is highly demanded for practical applications. Here, the representative PM6/Y6 active layer film, crosslinked by a photo‐crosslinkable small molecule 2,6‐bis(4‐azidobenzylidene)cyclohexanone (BAC) containing azide groups, exhibits a significantly enhanced stretchability...
Metallic zinc anodes in zinc‐ion batteries suffer from problematic Zn dendrite chemistry. Previous works have shown that preferred‐orientation crystal planes can help dendrite‐free metal anodes. This work reports a nanothickness (≈570 nm) AgZn3 coating to regulate the Zn growth. First, AgZn3@Zn anode avoids the problem, in Ag@Zn anode, that the rate of electrochemical Ag‐Zn alloying is slower than...
Photothermal therapy has gained widespread attention in cancer treatment, although its efficacy is suppressed due to the inflammatory response and immunosuppression, resulting in a discounted therapeutic effect. In this contribution, a high‐performance NIR absorption organic small chromophore is developed, which is encapsulated into Pluronic F‐127 to fabricate NIR absorption organic nanoparticles...
Pore‐structure design with increased ion‐diffusion ability is usually regarded as an effective strategy to improve K‐storage performance in hard carbon (HC). However, the relationship between porous structure and K+ migration behavior remains unclear and requires further exploration. Herein, a series of chemically activated hard carbon spheres (denoted as AHCSs) with controllable micro/mesopores structure...
The integration of highly luminescent CsPbBr3 quantum dots on nanowire waveguides has enormous potential applications in nanophotonics, optical sensing, and quantum communications. On the other hand, CsPb2Br5 nanowires have also attracted a lot of attention due to their unique water stability and controversial luminescent property. Here, the growth of CsPbBr3 nanocrystals on CsPb2Br5 nanowires is...
The electroreduction of CO2 to value‐added chemicals such as CO is a promising approach to realize carbon‐neutral energy cycle, but still remains big challenge including low current density. Covalent organic frameworks (COFs) with abundant accessible active single‐sites can offer a bridge between homogeneous and heterogeneous electrocatalysis, but the low electrical conductivity limits their application...
In article 1805308, Jiajun Gu and co‐workers assemble nanosized metal and semiconductor building blocks with various sizes and shapes into hierarchical structures in centimeter size, by introducing steric hindrance to compensate for environmentally sensitive hydrogen‐bonds and electrostatic interaction.
Assembling nanosized building blocks into macroscopic 3D complex structures is challenging. Here, nanosized metal and semiconductor building blocks with a variety of sizes and shapes (spheres, stars, and rods) are successfully assembled into a broad range of hierarchical (nanometer to micrometer) assemblies of functional materials in centimeter size using butterfly wings as templates. This is achieved...
Chiral properties of nanoscale materials are of importance as they dominate interactions with proteins in physiological environments; however, they have rarely been investigated. In this study, a systematic investigation is conducted for the adsorption behaviors of bovine serum albumin (BSA) onto the chiral surfaces of gold nanoparticles (AuNPs), involving multiple techniques and molecular dynamic...
Macroporous particles that combine the property features of spherical structures and porous materials are expected to find use over micro‐ and macroscopic length scales from miniaturized systems such as cell imaging, drug and gene delivery to industrial applications. However, the capacity for de novo design of such materials is still limited. Here, a spontaneous process to fabricate monodisperse multifunctional...
Carrier (electron and hole) transport layers (CTLs) are essential components for boosting the performance of various organic optoelectronic devices such as organic solar cells and organic light‐emitting diodes. Considering the drawbacks of conventional CTLs (easily oxidized/unstable, demanding/costly fabrication, etc.), transition metal oxides with good carrier transport/extraction and superior stability...
