Biomass‐based energy storage devices (BESDs) have drawn much attention to substitute traditional electronic devices based on petroleum or synthetic chemical materials for the advantages of biodegradability, biocompatibility, and low cost. However, most of the BESDs are almost made of reconstructed plant materials and exogenous chemical additives which constrain the autonomous and widespread advantages...
Heparin is a commonly applied blood anticoagulant agent in clinical use. After treatment, excess heparin needs to be removed to circumvent side effects and recover the blood‐clotting cascade. Most existing heparin antidotes rely on direct heparin binding and complexation, yet selective compartmentalization and sequestration of heparin would be beneficial for safety and efficiency. However, such systems...
Drop‐casting manganese oxide (MnO2) hollow nanospheres synthesized via a simple surface‐initiated redox route produces thin films exhibiting angle‐independent structural colors. The colors can rapidly change in response to high‐humidity dynamic water vapor (relative humidity > 90%) with excellent reversibility. When the film is triggered by dynamic water vapor with a relative humidity of ≈100%,...
Solar‐to‐Hydrogen Conversion
In article number 2202109, Chao Gu, Shi‐Kui Han, and co‐workers demonstrate an all‐in‐one strategy for the selective‐epitaxial hybridization of unique tripartite semiconducting sulfides, denoted as CuInS2–Cd(In) S–MoS2. The integrated architectures exhibit superior solar‐to‐hydrogen conversion performance due to their enhanced capabilities for solar absorption and charge...
The design and synthesis of advanced semiconductors is crucial for the full utilization of solar energy. Herein, colloidal selective‐epitaxial hybrid of tripartite semiconducting sulfides CuInS2Cd(In)SMoS2 heteronanostructures (HNs) via lateral‐ and vertical‐epitaxial growths, followed by cation exchange reactions, are reported. The lateral‐epitaxial CuInS2 and Cd(In)S enable effective visible to...
Inspired by the 2D bilayer lipid membranes in nature, a unique supramolecular “push–pull” synergetic strategy toward self‐assembled 2D organic crystals (2DOCs) is proposed in this work, which can effectively suppress the interlayer 3D stacking while maintaining the assembly of the intralayer for 2D growth. For this purpose, a model molecule PF‐Py consisting of a planar supramolecular “attractor” and...
2D semiconductors have attracted tremendous attention as an atomically thin channel for transistors with superior immunity to short‐channel effects. However, with atomic thin structure, the delicate 2D lattice is not fully compatible with conventional lithography processes that typically involve high‐energy photon/electron radiation and unavoidable polymer residues, posing a key limitation for high...
Interfacial engineering and heterostructures designing are two efficient routes to improve photoelectric characteristics of a photodetector. Herein, a Ti3C2 MXene/Si heterojunction photodetector with ultrahigh specific detectivity (2.03 × 1013 Jones) and remarkable responsivity (402 mA W−1) at zero external bias without decline as with increasing the light power is reported. This is achieved by chemically...
Heavy metal ions (HMIs) are one of the major environmental pollution problems currently faced. To monitor and control HMIs, rapid and reliable detection is required. Electrochemical analysis is one of the promising methods for on‐site detection and monitoring due to high sensitivity, short response time, etc. Recently, nanometal oxides with special surface physicochemical properties have been widely...
Combined with the synchrotron radiation X‐ray absorption fine structure (XAFS) spectrum, density functional theory (DFT) calculations, theoretical electrochemical numerical simulations, etc., Chu‐Hong Lin, Xing‐Jiu Huang, Wen‐Qing Liu, and co‐workers summarize and discuss the effect of crystal facet and crystal phase, defects and oxygen vacancies, and oxidation states cycle of nano‐metal oxides in...
Metal hydroxide nanomaterials are widely applied in the energy and environment fields. The electrochemical performance of such materials is strongly dependent on their crystal phases. However, as there are always multiple factors relating to the phase‐dependent electrochemistry, it is still difficult to identify the determining one. The well‐defined crystal phases of α‐ and β‐FeOOH nanorods are characterized...
Graphyne (GY) is a new type of carbon allotrope, which is viewed as a rapidly rising star in the carbon family referred to as 2D carbon allotropes due to its extraordinary properties. Considering the dynamic nature of the alkyne metathesis reaction, a hydrogen‐substituted graphyne (HsGY) film is successfully synthesized on a gas/liquid interface using 1,3,5‐tripynylbenzene (TPB) as the precursor....
Over the last decades, water‐based lyotropic liquid crystals of nucleic acids have been extensively investigated because of their important role in biology. Alongside, solvent‐free thermotropic liquid crystals (TLCs) from DNA are gaining great interest, owing to their relevance to DNA‐inspired optoelectronic applications. Up to now, however, only the smectic phase of DNA TLCs has been reported. The...
Rational design and development of new‐generation photocatalysts with high hydrogen evolution activity is recognized as an effective strategy to settle energy crisis. To this regard, hybrid photocatalysts of Au quantum dots embedded in rimous cadmium sulfide nanospheres are synthesized by using a simple hydrothermal process followed by photoreduction. The rimous cadmium sulfide nanospheres with rough...
