This work is inspired by oysters converting worthless sand into precious pearls. In article number 2000553, Chen Wang and co‐workers present the “trash into treasure” process, which efficiently promotes antibacterial therapy and wound healing. The confinement effect of 2D Al‐metal–organic frameworks (MOFs) maintains gold nanoparticles (AuNPs) as ultrasmall without gathering and makes them exhibit...
Aqueous rechargeable zinc‐based batteries have sparked a lot of enthusiasm in the energy storage field recently due to their inherent safety, low cost, and environmental friendliness. Although remarkable progress has been made in the exploration of performance so far, there are still many challenges such as low working voltage and dissolution of electrode materials at the material and system level...
Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest malignant tumors with extremely poor prognosis due to the later stage diagnosis when surgical resection is no longer applicable. Alternatively, the traditional gene therapy which drives pancreatic cancer cells into an inactive state and inhibiting the proliferation and metastasis, presents potentials to safely inhibit pancreatic cancer...
Hierarchical porous carbons (HPCs) are highly efficient supports for various remarkable catalytic systems. However, templates are commonly utilized for the preparation of HPCs, and the postremoval of the templates is uneconomical, time‐consuming, and harmful for the environment in most cases. Herein, a new humidity‐induced nontemplating strategy is developed to prepare 1D HPC with rich topologies...
In article number 2001721, Takeshi Sakamoto, Hiroyuki Katayama, Takashi Kato, and co‐workers achieve high virus removal for liquid‐crystalline water treatment membranes. The liquid crystal forms 2D lamellar nanochannels allowing superior virus removal while maintaining efficient water flux. The removal efficiency is 99.999994%. Self‐assembly of smectic liquid crystals and subsequent photopolymerization...
In article number 2000228, Luying Li, Tianyou Zhai, and co‐workers prepare large‐size BiOCl flakes with thickness down to a monolayer via salt‐assisted chemical vapor deposition. The 2D BiOCl photodetectors exhibit high responsivity throughout the solar‐blind range at room and high temperatures. The success in fabrication of atomically thin BiOCl photodetectors opens opportunities for their potential...
The high‐temperature molten‐salt method is an important inorganic synthetic route to a wide variety of morphological phenotypes. However, its utility is limited by the fact that it is typically incapable of producing ultrathin (<5 nm diameter) nanowires, which have a crucial role in novel nanotechnology applications. Herein, a rapid molten salt‐based synthesis of sub‐5‐nm‐sized nanowires of hexagonal...
Regulating the coordination environment of atomically dispersed catalysts is vital for catalytic reaction but still remains a challenge. Herein, an ionic exchange strategy is developed to fabricate atomically dispersed copper (Cu) catalysts with controllable coordination structure. In this process, the adsorbed Cu ions exchange with Zn nodes in ZIF‐8 under high temperature, resulting in the trapping...
Fabrication of hierarchical nanosheet arrays of 1T phase of transition‐metal dichalcogenides is indeed a critical task, but it holds immense potential for energy storage. A single‐step strategy is employed for the fabrication of stable 1T‐MnxMo1–xS2–ySey and MoFe2S4–zSez hierarchical nanosheet arrays on carbon cloth as positive and negative electrodes, respectively. The flexible asymmetric supercapacitor...
It is a significant challenge to achieve controllable self‐assembly of superstructures for biological applications in living cells. Here, a two‐layer core–satellite assembly is driven by a Y‐DNA, which is designed with three nucleotide chains that hybridized through complementary sequences. The two‐layer core–satellite nanostructure (C30S5S10 NS) is constructed using 30 nm gold nanoparticles (Au NPs)...
As a rising star in the family of graphene analogues, germanene shows great potential for electronic and optical device applications due to its unique structure and electronic properties. It is revealed that the hydrogen terminated germanene not only maintains a high carrier mobility similar to that of germanene, but also exhibits strong light–matter interaction with a direct band gap, exhibiting...
A magnetic urchin‐like microswimmer based on sunflower pollen grain (SPG) that can pierce the cancer cell membrane and actively deliver therapeutic drugs is reported. These drug loaded microperforators are fabricated on a large scale by sequentially treating the natural SPGs with acidolysis, sputtering, and vacuum loading. The microswimmers exhibit precise autonomous navigation and obstacle avoidance...
Mitochondria, which are important mediators for cancer initiation, growth, metastasis, and drug resistance, have been considered as a major target in cancer therapy. Herein, an acid‐activated mitochondria‐targeted drug nanocarrier is constructed for precise delivery of nitric oxide (NO) as an adenosine triphosphate (ATP) suppressor to amplify the therapeutic efficacy in cancer treatments. By combining...
The formation of a stable solid electrolyte interphase (SEI) is a prerogative for functional lithium metal batteries. Herein, the formation and evolution of such SEI in contact with glyme‐based electrolytes is investigated under open circuit voltage and several constant current cycles. An important conclusion of the study is that LixSy species are nonbeneficial SEI components, compared to the Li3N...
The development of high‐performance but low‐cost catalysts for the electrochemical oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) is of central importance for realizing the prevailing application of metal–air batteries. Herein a facile route is devised to synthesize S, N codoped carbon cubes embedding Co–Fe carbides by pyrolyzing the Co–Fe Prussian blue analogues (PBA) coated...
Metal sulfides have aroused considerable attention for efficient sodium storage because of their high capacity and decent redox reversibility. However, the poor rate capability and fast capacity decay greatly hinder their practical application in sodium‐ion batteries. Herein, a self‐template‐based strategy is designed to controllably synthesize hierarchical microoctahedra assembled with Cu2S/MoS2...
Hypoxia severely impedes photodynamic therapy (PDT) efficiency. Worse still, considerable tumor metastasis will occur after PDT. Herein, an organic superoxide radical (O2∙−) nano‐photogenerator as a highly effcient type I photosensitizer with robust vascular‐disrupting efficiency to combat these thorny issues is designed. Boron difluoride dipyrromethene (BODIPY)‐vadimezan conjugate (BDPVDA) is synthesized...
Proteins, like actors, play different roles in specific applications. In the past decade, significant achievements have been made in protein‐engineered biomedicine for cancer therapy. Certain proteins such as human serum albumin, working as carriers for drug/photosensitizer delivery, have entered clinical use due to their long half‐life, biocompatibility, biodegradability, and inherent nonimmunogenicity...
As one of the common reactive oxygen species, H2O2 has been widely used for combating pathogenic bacterial infections. However, the high dosage of H2O2 can induce undesired damages to normal tissues and delay wound healing. In this regard, peroxidase‐like nanomaterials serve as promising nanozymes, thanks to their positive promotion toward the antibacterial performance of H2O2, while avoiding the...
