Photothermal therapy (PTT) is demonstrated to be an effective methodology for cancer treatment. However, the relatively low photothermal conversion efficiency, limited tumor accumulation, and penetration still remain to be challenging issues that hinder the clinical application of PTT. Herein, the core–shell hierarchical nanostructures induced by host–guest interaction between water‐soluble pillar[5]arene...
The interface plays a pivotal role in stabilizing metal anode. Extensive studies have been made but systematic research is lacking. In this study, preliminary studies are conducted to explore the prime conditions of interfacial modification to approach the practical requirements. Critical factors including reaction kinetics, transport rate, and modulus are identified to affect the Zn anode morphology...
The morphology regulation of covalent triazine frameworks (CTFs) is a great challenge, which may be due to the difficulty in controlling its morphology by traditional synthesis methods. Herein, a general approach to fabricate morphology controllable CTFs by a mild polycondensation reaction in mixed solvents without any templating agents is reported. As a proof of concept, a type of crystalline CTFs...
2D lamellar materials can offer high surface area and abundant reactive sites, thus showing an appealing prospect in photocatalytic hydrogen evolution. However, it is still difficult to build cost‐efficient photocatalytic hydrogen evolution systems based on 2D materials. Herein, an in situ growth method is employed to build 2D/2D heterojunctions, with which 2D Ni‐based metal–organic layers (Ni‐MOLs)...
A ferromagnetic metal nanolayer with a large perpendicular magnetic anisotropy, small saturation magnetization, and small magnetic damping constant is a crucial requirement for high‐speed spintronic devices. Fabrication of these devices on Si/SiO2 amorphous substrates with polycrystalline structure is also strongly desired for the mass production industry. This study involves the investigation of...
Hydrazine‐assisted hybrid water electrolysis is an energy‐saving approach to produce high‐purity hydrogen, whereas the development of pH‐universal bifunctional catalysts encounters a grand challenge. Herein, a phase‐selective synthesis of ruthenium phosphide compounds hybrid with carbon forming pancake‐like particles (denoted as RuxP/C‐PAN, x = 1 or 2) is presented. The obtained RuP/C‐PAN exhibits...
Genome engineering of cells using CRISPR/Cas systems has opened new avenues for pharmacological screening and investigating the molecular mechanisms of disease. A critical step in many such studies is the intracellular delivery of the gene editing machinery and the subsequent manipulation of cells. However, these workflows often involve processes such as bulk electroporation for intracellular delivery...
In response to the application requirements of secondary batteries at low temperature, an all‐organic dual‐ion battery with calcium perchlorate contained acetonitrile as the electrolyte (CAN‐ODIB) is fabricated in this work. The electrochemical energy is stored in CAN‐ODIB via the association and disassociation of calcium and perchlorate ions in perylene diimide‐ethylene diamine/carbon black composite...
Trained immunity is a recently described phenomenon whereby cells of the innate immune system undergo long‐term epigenetic and/or metabolic reprogramming following a short‐term interaction with microbes or microbial products. Here, it is shown that 2D transition metal dichalcogenides (TMDs) trigger trained immunity in primary human monocyte‐derived macrophages. First, aqueous dispersions of 2D crystal...
Many materials with nanofluidic channels are exploited to achieve salinity gradient energy conversion. However, most materials are fragile, difficult to process, or only prepared into a limited size, which greatly restricts their practical application in the future. Herein, a covalent organic polymers membrane with high mechanical property and stability is fabricated, which can keep integrity in harsh...
