Tumor cells adapt to excessive oxidative stress by actuating reactive oxygen species (ROS)‐defensing system, leading to a resistance to oxidation therapy. In this work, self‐delivery photodynamic synergists (designated as PhotoSyn) are developed for oxidative damage amplified tumor therapy. Specifically, PhotoSyn are fabricated by the self‐assembly of chlorine e6 (Ce6) and TH588 through π–π stacking...
Nitrogen‐doped nanocarbons are widely used as supports for metal‐heterogeneous catalytic conversions. When nitrogen‐doped nanocarbon supports are used to disperse metallic nanoparticles (MNPs), the nitrogen dopant can enhance MNPs electron density to reach higher catalytic activity and promote MNPs stability through anchoring effects. However, the precise identification of active nitrogen species...
Molybdenum carbide (MoxC)‐based nanomaterials have shown competitive performances for energy conversion applications based on their unique physicochemical properties. A large surface area and proper surface atomic configuration are essential to explore potentiality of MoxC in electrochemical applications. Although considerable efforts are made on the development of advanced MoxC‐based catalysts for...
1D nanostructured photoelectrodes are promising for application as photoelectrochemical (PEC) devices for solar energy conversion into hydrogen (H2) owing to the optical, structural, and electronic advantages. Titanium dioxide (TiO2) is the most investigated candidate as a photoelectrode due to its good photostability, low production cost, and eco‐friendliness. The obstacle for TiO2's practical application...
Lithium‐ion batteries (LIBs) are widely used in electric vehicles and portable electronic devices due to their high energy density, long cycle life, environmental friendliness, and negligible memory effect, though they also suffer from low power density, safety issues, and an aging effect. Cobalt chalcogenides/phosphides as promising anode materials have attracted intensive interests due to their...
Developing cost‐effective and high‐efficiency electrocatalysts toward alkaline oxygen evolution reaction (OER) is crucial for water splitting. Amorphous bimetallic NiFe‐based (oxy)hydroxides have excellent OER activity under alkaline media, but their poorly electrical conductivity impedes the further improvement of their catalytic performance. Herein, a bimetallic NiFe‐based heterostructure electrocatalyst...
Considerable efforts have been exerted to understand the formation and properties of the solid electrolyte interphase (SEI) in sodium ion batteries. However, the puzzling existence and role of SEI behind the huge volume changes of the graphite electrodes need to be answered. Herein, the reason of how ether‐derived SEI maintains excellent reversibility despite the huge volume changes during cycling...
Doped 2,2′,7,7′‐tetrakis(N,N‐di‐p‐methoxyphenylamine)‐9,9′‐spirobifluorene (spiro‐MeOTAD), which acts as a hole‐transporting layer (HTL), endows perovskite solar cells (PSCs) with excellent performance. However, the intrinsically hygroscopic nature of lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) dopants also aggravates the moisture instability of PSCs. In this work, the origins of the moisture...
The performance of perovskite nanocrystals (NCs) in optoelectronics and photocatalysis is severely limited by the presence of large amounts of crystal boundaries in NCs film that greatly restricts energy transfer. Creating heterostructures based on perovskite NCs and 2D materials is a common approach to improve the energy transport at the perovskite/2D materials interface. Herein, methylamine lead...
Nucleic acid‐based macromolecules have paved new avenues for the development of therapeutic interventions against a spectrum of diseases; however, their clinical translation is limited by successful delivery to the target site and cells. Therefore, numerous systems have been developed to overcome delivery challenges to nucleic acids. From the viewpoint of clinical translation, it is highly desirable...
Cucurbit[8]uril (CB[8]) is unique and notable in the cucurbit[n]uril family, since it has a relatively large cavity and thus is able to simultaneously accommodate two guest molecules. Typically, an electron‐deficient first guest and an electron‐rich second guest can be bound by CB[8] to form a stable 1:1:1 heteroternary supramolecular complex. Additionally, two homo guests can also be strongly dimerized...
The degradation of intervertebral discs (IVD), a typical hierarchical structured tissue, causes serious neck and back pain. The current methods cannot fully reconstitute the unique structure and function of native IVD. In this study, by reverse reconstruction of the structure of native IVD and bioprinting bacterial cellulose (BC) nanofibers with a high‐throughput optimized micropattern screening microchip,...
Bacterial infections, especially multidrug‐resistant bacterial infections, are an increasingly serious problem in the field of wound healing. Herein, bacterial cellulose (BC) decorated by 4,6‐diamino‐2‐pyrimidinethiol (DAPT)‐modified gold nanoparticles (Au‐DAPT NPs) is presented as a dressing (BC‐Au‐DAPT nanocomposites) for treating bacterially infected wounds. BC‐Au‐DAPT nanocomposites have better...
Organic semiconductor micro‐/nanocrystals with regular shapes have been demonstrated for many applications, such as organic field‐effect transistors, organic waveguide devices, organic solid‐state lasers, and therefore are inherently ideal building blocks for the key circuits in the next generation of miniaturized optoelectronics. In the study, blue‐emissive organic molecules of 1,4‐bis(2‐methylstyryl)benzene...
The nanoplatform GNR‐ACPP‐PpIX (designated as GNR‐ACPI) is designed for dual image guided combined activatable photodynamic therapy (PDT) and photothermal therapy (PTT). In GNR‐ACPI, gold nanorods (GNRs) are modified with a protoporphyrin (PpIX, a PDT agent) conjugated activatable cell penetrating peptide (ACPP), which consists of the matrix metalloproteinases‐2 (MMP‐2) sensitive peptide sequence...
TiO2 has excellent electrochemical properties but limited solar photocatalytic performance in light of its large bandgap. One important class of visible‐wavelength sensitizers of TiO2 is based on ZnFe2O4, which has shown fully a doubling in performance relative to pure TiO2. Prior efforts on this important front have relied on presynthesized nanoparticles of ZnFe2O4 adsorbed on a TiO2 support; however,...
