The poor efficiency and low immunogenicity of photodynamic therapy (PDT), and the immunosuppressive tumor microenvironment (ITM) lead to tumor recurrence and metastasis. In this work, TCPP‐TER‐Zn@RSV nanosheets (TZR NSs) that co‐assembled from the endoplasmic reticulum (ER)‐targeting photosensitizer TCPP‐TER‐Zn nanosheets (TZ NSs for short) and the autophagy promoting and indoleamine‐(2, 3)‐dioxygenase...
The interaction between catalyst and support plays an important role in electrocatalytic hydrogen evolution (HER), which may explain the improvement in performance by phase transition or structural remodeling. However, the intrinsic behavior of these catalysts (dynamic evolution of the interface under bias, structural/morphological transformation, stability) has not been clearly monitored, while the...
Constructing heterogeneous nanostructures is an efficient strategy to improve the electrical and ionic conductivity of metal chalcogenide‐based anodes. Herein, ZnS/SnO2 quantum dots (QDs) as p‐n heterojunctions that are uniformly anchored to reduced graphene oxides (ZnS‐SnO2@rGO) are designed and engineered. Combining the merits of fast electron transport via the internal electric field and a greatly...
Disordered crystallization and poor phase stability of mixed halide perovskite films are still the main factors that compromise the performance of inverted wide bandgap (WBG; 1.77 eV) perovskite solar cells (PSCs). Great difficulties are evidenced due to the very different crystallization rates between I‐ and Br‐based perovskite components through DMSO‐alone assisted anti‐solvent process. Here, a...
Combination therapies involving metabolic regulation and immune checkpoint blockade are considered an encouraging new strategy for cancer therapy. However, the effective utilization of combination therapies for activating tumor‐associated macrophages (TAMs) remains challenging. Herein, a lactate‐catalyzed chemodynamic approach to activate the therapeutic genome editing of signal‐regulatory protein...
Although photodynamic immunotherapy has been promoted in the clinical practice of cholangiocarcinoma, the insensitivity to photodynamic immunotherapy remains to be a great problem. This can be largely attributed to an immune‐suppressive tumor microenvironment (TME) manifested as immature myeloid cells and exhausted cytotoxic T lymphocytes. Here, a three‐in‐one oncolytic adenovirus system PEG‐PEI‐Adv‐Catalase‐KillerRed...
137Cs and 90Sr are hazardous to ecological environment and human health due to their strong radioactivity, long half‐life, and high mobility. However, effective adsorption and separation of Cs+ and Sr2+ from acidic radioactive wastewater is challenging due to stability issues of material and the strong competition of protons. Herein, a K+‐activated niobium germanate (K‐NGH‐1) presents efficient Cs...
Spinal cord injury (SCI) can lead to devastating autonomic dysfunction. One of the most challenging issues for functional repair in SCI is the secondary damage caused by the increased release of glutamate and free Ca2+ from injured cells. Here, an in situ assembled trapping gel (PF‐SA‐GAD) is developed to sweep glutamate and Ca2+, promoting SCI repair. The hydrogel solution is a mixture of recombinant...
Inverted‐structure perovskite solar cells (PSCs) are known for their superior device stability. However, based on nickel‐oxide (NiOx) substrate, disordered crystallization and bottom interface instability of perovskite film are still the main factors that compromise the power conversion efficiency (PCE) of PSCs. Here, 2D perovskite of thiomorpholine 1,1‐dioxide lead iodide (Td2PbI4) is introduced...
In contrast to the 2D organic‐inorganic hybrid Ruddlesden–Popper halide perovskites (RPP), a new class of 2D all inorganic RPP (IRPP) has been recently proposed by substituting the organic spacers with an optimal inorganic alternative of cesium cations (Cs+). Nevertheless, the synthesis of high‐membered 2D IRPPs (n > 1) has been a very challenging task because the Cs+ need to act as both spacers...
A promising anode material consisting of bimetallic thiophosphate ZnxCo1−xPS3 and CoS2 with 2D/3D heterostructure is designed and prepared by an effective chemical transformation. Density functional theory calculations illustrate that the Zn2+ can effectively modulate the electrical ordering of ZnxCo1−xPS3 on the nanoscale: the reduced charge distribution emerging around the Zn ions can enhance the...
The inevitable bleeding during tumor resection greatly increases the risk of tumor recurrence caused by metastasis of cancer cells with blood, and hemostasis and prevention of post‐operation tumor recurrence is still a challenge. However, a biomaterials approach for rapid hemostasis during tumor resection and simultaneous prevention of tumor recurrence is rarely reported. Here, zeolitic imidazolate...
In article number 2100637, Vinayak P. Dravid, Jinsong Wu, and co‐workers perform a systematic study of WS2 nanoflakes as the anode for lithium‐ion and sodium‐ion batteries. It is found that compared to LIBs, SIBs exhibit a higher reversible sodium storage capacity and superior cyclability. The results show a direct correlation between the reaction dynamics of lithiated/sodiated WS2 nanoflakes and...
WS2 nanoflakes have great potential as electrode materials of lithium‐ion batteries (LIBs) and sodium‐ion batteries (SIBs) because of their unique 2D structure, which facilitates the reversible intercalation and extraction of alkali metal ions. However, a fundamental understanding of the electrochemical lithiation/sodiation dynamics of WS2 nanoflakes especially at the nanoscale level, remains elusive...
Multinary layered 2D nanomaterials can exhibit distinct physicochemical properties and innovative applications as compared to binary 2D nanomaterials due to their unique crystal structures. However, it still remains a challenge for the high‐yield preparation of high‐quality multinary 2D nanosheets. Here, the high‐yield and large‐scale production of two quaternary metal thiophosphate nanosheets are...
The deterioration of water resources due to oil pollution, arising from oil spills, industrial oily wastewater discharge, etc., urgently requires the development of novel functional materials for highly efficient water remediation. Recently, superhydrophilic and underwater superoleophobic materials have drawn significant attention due to their low oil adhesion and selective oil/water separation. However,...
The novel application of two‐dimensional (2D) single‐layer ternary chalcogenide nanosheets as “capture‐release” fluorescence‐based biomolecular nanosensors is demonstrated. Fluorescently labeled biomolecular probe is first captured by the ultrathin Ta2NiS5 nanosheets and then released upon adding analyte containing a target biomolecule due to the higher probe‐target affinity. Here, the authors use...
A facile in situ synthetic method is developed to synthesize metal sulfide nanoparticles based on 2D M‐TCPP (M = Cu, Cd, or Co, TCPP = tetrakis(4‐carboxyphenyl)porphyrin)) metal‐organic framework nanosheets. The obtained CuS/Cu‐TCPP composite nanosheet is used as the active material in photoelectrochemical cells, showing notably increased photocurrent due to the improved exciton separation and charge...
The high‐yield and scalable production of single‐layer ternary transition metal dichalcogenide nanosheets with ≈66% of metallic 1T phase, including MoS2xSe2(1–x) and MoxW1–xS2 is achieved via electrochemical Li‐intercalation and the exfoliation method. Thin film MoS2xSe2(1‐x) nanosheets drop‐cast on a fluorine‐doped tin oxide substrate are used as an efficient electrocatalyst on the counter electrode...
