Chemo‐phototherapy has emerged as a promising approach to complement traditional cancer treatment and enhance therapeutic effects. However, it still faces the challenges of drug efflux transporter‐mediated chemoresistance and heat shock proteins (HSPs)‐mediated phototherapy tolerance, which both depend on an excessive supply of adenosine triphosphate. Therefore, manipulating energy metabolism to impair...
2D materials are now at the forefront of state‐of‐the‐art nanotechnologies due to their fascinating properties and unique structures. As expected, low‐cost, high‐volume, and high‐quality 2D materials play an important role in the applications of flexible devices. Although considerable progress has been achieved in the integration of a series of novel 2D materials beyond graphene into flexible devices,...
Literature reports have shown that in primary structures, single‐atom catalysts exhibit better performance than cluster and nanoparticles due to their maximum atom utilization and the fine‐tuning of the electronic structure of the active sites. Hierarchical structures have recently been extensively studied because of increased active sites and orderliness of channels significantly improves the catalytic...
Aqueous zinc‐ion batteries are a low‐cost and safe energy storage system, but suffer from detrimental side reactions and Zn dendrites due to the strong interactions between Zn2+ and water molecules in the electrolytes, and random Zn2+ deposition on the anode surface. Here, an electrolyte involving a dual‐functional additive of polyethylene glycol (PEG) to bypass these issues is reported. The electrolyte...
MnO2‐based material is one of the most promising cathode candidates of aqueous zinc‐ion batteries (ZIBs), but its commercialization is hindered by the sluggish reaction kinetics and poor structural stability. Herein, a hierarchical framework consisting of core–shell structured carbon nanotubes@K‐birnessite‐MnO2 enwrapped by graphene/carbon black bicomponent networks (CNT@KMO@GC) via a simple method...
Aqueous Zinc‐Ion Batteries
In article number 2104557, Lei Li and co‐workers develop a solution‐processed method to fabricate a hierarchical K‐birnessite‐MnO2‐carbon framework vividly depicted by the dragon flying in the clouds. The dragon with scales represents carbon nanotubes decorated by K‐birnessite‐MnO2 porous nanoflakes, the clouds stand for graphene, and the pearls in the dragon claws are carbon...
Colloidal all‐inorganic perovskites nanocrystals (NCs) have emerged as a promising material for display and lighting due to their excellent optical properties. However, blue emissive NCs usually suffer from low photoluminescence quantum yields (PLQYs) and poor stability, rendering them the bottleneck for full‐color all‐perovskite optoelectronic applications. Herein, a facile approach is reported to...
Aromatic imides are a class of attractive organic materials with inherently electroactive groups and large π electron‐deficient scaffolds, which hold potential as electrode materials for organic secondary batteries (OSBs). However, the undecorated aromatic imides are usually plagued by low capacity, high solubility in electrolyte, and poor electronic/ionic conductivity. Molecular engineering has been...
Memristor, processing data storage and logic operation all‐in‐one, is an advanced configuration for next generation computer. In this work, a bismuth doped tin oxide (Bi:SnO2) memristor with ITO/Bi:SnO2/TiN structure has been fabricated. Observing from transmission electron microscope (TEM) for the Bi:SnO2 device, it is found that the bismuth atoms surround the surface of SnO2 crystals to form the...
In article number 2003816, Lei Li and co‐workers implement a proof‐of‐concept solution‐processed all‐V2O5 battery with symmetrical electrode structure. The electrodes are prepared via the solution‐processed method, indicated by the river with the boat. V2O5 works as both cathode and anode. The storage/release charges via Li+ intercalation/de‐intercalation in V2O5 like the balanced mutual transformation...
Exploring new battery technologies will promote the advance of energy storage systems. Designing a symmetrical‐structured rechargeable battery with the same electrode materials is a meaningful exploration for battery technology. Here, a solution‐processed all‐V2O5 rechargeable battery with V2O5 as both anode and cathode is presented, in which the anionic/cationic redox reactions are decoupled by precisely...
Overproduced hydrogen sulfide (H2S) is of vital importance for the progress of colon cancer and promotes cancer cellular proliferation. Devising pharmacological nanomaterials for tumor‐specific H2S activation will be significant for precise colon cancer treatment. Herein, a biocompatible fusiform iron oxide‐hydroxide nanospindles (FeOOH NSs) nanosystem for magnetic resonance imaging (MRI), ferroptosis,...
In article number 1604077, by Ming Li, Yunbin He and co‐workers, demonstrate that hydrogen‐bonding (a weak and reversible interaction) can assemble conjugated polymer chains towards a free‐standing 2D material. The H‐bonding allows further splitting of the material into ribbons, which can re‐assemble, similar to a zipper, leading to the first example of a healable 2D material.
In many 2D materials reported thus far, the forces confining atoms in a 2D plane are often strong interactions, such as covalent bonding. Herein, the first demonstration that hydrogen (H)‐bonding can be utilized to assemble polydiacetylene (a conductive polymer) toward a 2D material, which is stable enough to be free‐standing, is shown. The 2D material is well characterized by a large number of techniques...
