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...
Nucleation and Growth of Bubbles
In article number 2103301, Yongming Hu, Chee Leung Mak, Linfeng Fei, and co‐workers present the nucleation and growth mechanisms of bubbles extracted in TEM by monitoring the decomposition of a solid precursor. Under electron‐beam irradiation, the 2D Ni(OH)2 flake emits gaseous species within the solid matrix, leading to nanoscale bubbling processes via a three‐step...
The nucleation and growth of bubbles within a solid matrix is a ubiquitous phenomenon that affects many natural and synthetic processes. However, such a bubbling process is almost “invisible” to common characterization methods because it has an intrinsically multiphased nature and occurs on very short time/length scales. Using in situ transmission electron microscopy to explore the decomposition of...
Optical encryption with easy operation, multichannel and high security has been one of the most significant technologies for information security. Stimuli‐responsive luminescent materials have emerged as an ideal candidate for optical encryption, owing to its smart responsive property and high security. Herein, a type of light‐responsive multicolor luminescent materials for high‐security information...
In aquatic environments, a large number of ecological macromolecules (e.g., natural organic matter (NOM), extracellular polymeric substances (EPS), and proteins) can adsorb onto the surface of engineered nanomaterials (ENMs) to form a unique environmental corona. The presence of environmental corona as an eco–nano interface can significantly alter the bioavailability, biocompatibility, and toxicity...
Developing high‐voltage cathode materials is critical for sodium‐ion batteries to boost energy density. NASICON (Na super‐ionic conductor)‐structured NaxMnM(PO4)3 materials (M represents transition metal) have drawn increasing attention due to their features of robust crystal framework, low cost, as well as high voltage based on Mn4+/Mn3+ and Mn3+/Mn2+ redox couples. However, full activation of Mn...
Massive volume change of active materials in lithium/sodium ion batteries (LIB/SIB) causes severe structural collapse of electrodes and fast capacity decay of batteries. Here, a coaxial composite of single‐wall carbon nanotube bundle (SWCNTB/SnO2) nanoparticles (NPs)/N‐doped carbon shell (SWCNTB@SnO2@C) is constructed, where SWCNTBs with exceptional elasticity are explored as a self‐adaptive substrate...
