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 fabrication of periodic macroporous (PM) in Nb2O5 via morphological control is crucial for improving the photocatalytic hydrogen evolution efficiency. In this study, Nb2O5 with PM is synthesized using a straightforward colloidal crystal templating approach. This material features an open, interconnected macroporous architecture with nanoscale walls, high crystallinity, and substantial porosity...
DNA nanostructures with diverse biological functions have made significant advancements in biomedical applications. However, a universal strategy for the efficient production of DNA nanostructures is still lacking. In this work, a facile and mild method is presented for self‐assembling polyethylenimine‐modified carbon dots (PEI‐CDs) and DNA into nanospheres called CANs at room temperature. This makes...
Using solid nanoparticles (NPs) as catalysts is the most effective method to achieve catalytic growth of single‐walled carbon nanotubes (SWCNTs) with ultrapure chirality. Until now, SWCNTs with a suitable chirality purity have not been prepared in experiments. That is, the evolution of solid NPs during the catalytic growth of SWCNTs is in contradiction with the original concept of a changeless structure...
At present, poor stability and carrier transfer efficiency are the main problems that limit the development of perovskite‐based photoelectric technologies. In this work, hydrogen‐bonded cocrystal‐coated perovskite composite (PeNCs@NHS‐M) is easily obtained by inducing rapid crystallization of melamine (M) and N‐hydroxysuccinimide (NHS) with PeNCs as the nuclei. The outer NHS‐M cocrystal passivates...
The safety, low cost, and high power density of aqueous Zn‐based devices (AZDs) appeal to large‐scale energy storage. Yet, the presence of hydrogen evolution reaction (HER) and chemical corrosion in the AZDs leads to local OH− concentration increasement and the formation of ZnxSOy(OH)z•nH2O (ZHS) by‐products at the Zn/electrolyte interface, causing instability and irreversibility of the Zn‐anodes...
Knee replacement surgery confronts challenges including patient dissatisfaction and the necessity for secondary procedures. A key requirement lies in dual‐modal measurement of force and temperature of artificial joints during postoperative monitoring. Here, a novel non‐toxic near‐infrared (NIR) phosphor Sr3Sn2O7:Nd, Yb, is designed to realize the dual‐modal measurement. The strategy is to entail phonon‐assisted...
Porous substrate electroporation (PSEP) is a promising new method for intracellular delivery, yet fundamentals of PSEP are not well understood, especially the intermediate processes leading to delivery. PSEP is an electrical method, yet the relationship between PSEP and electrical impedance remains underexplored. In this study, a device capable of measuring impedance and performing PSEP is developed...
Electrocatalytic nitrogen reduction reaction (NRR) paves a sustainable way to produce NH3 but suffering from the relatively low NH3 yield and poor selectivity. High‐performance NRR catalysts and a deep insight into the structure‐performance relationship are higher desired. Herein, a molten‐salt approach is developed to synthesize tiny CeO2 nanoparticles anchored by ultra‐thin MoN nanosheets as advanced...
Ferroptosis is a new form of regulated cell death featuring iron‐dependent lipid peroxides accumulation to kill tumor cells. A growing body of evidence has shown the potential of ferroptosis‐based cancer therapy in eradicating refractory malignancies that are resistant to apoptosis‐based conventional therapies. In recent years, studies have reported a number of ferroptosis inducers that can increase...
The interfacial carrier non‐radiative recombination caused by buried defects in electron transport layer (ETL) material and the energy barrier severely hinders further improvement in efficiency and stability of perovskite solar cells (PSCs).

Single‐atom metal‐doped M–N–C (M═Fe, Co, Mn, or Ni) catalysts exhibit excellent catalytic activity toward oxygen reduction reactions (ORR). However, their performance still has a large gap considering the demand for their practical applications. This study reports a high‐performance dual single‐atom doped carbon catalyst (HfCo–N–C), which is prepared by pyrolyzing Co and Hf co‐doped ZIF‐8 . Co and...
Oxygen evolution reaction (OER) plays a critical role in energy conversion technologies. Significant progress has been made in alkaline conditions. In contrast, it remains a challenge to develop stable OER electrocatalysts in acidic conditions. Herein, a new strategy is reported to stabilize single atoms integrated into cobalt oxide spinel structure with interstitial carbon (Ru0.27Co2.73O4), where...
Supported noble metal nanoparticles (NMNPs) are appealing for energy and environment catalysis. To facilitate the loading of NMNPs, in situ reduction of Mn+ on the support with extra reductants/surfactants is adopted, but typically results in aggregated NMNPs with uneven size distributions or blocked active sites of the NMNPs. Herein, the use of cobalt layered double hydroxide (Co‐LDH) is proposed...
Perovskite solar cells (PSCs) have achieved revolutionary progress during the past decades with a rapidly boosting rate in power conversion efficiencies from 3.8% to 26.1%. However, high‐efficiency PSCs with organic hole‐transporting materials (HTMs) suffer from inferior long‐term stability and high costs. The replacement of organic HTMs with inorganic counterparts such as metal oxides can solve the...
The growth state of tumor cells is strictly affected by the specific abnormal redox status of the tumor microenvironment (TME). Moreover, redox reactions at the biological level are also central and fundamental to essential energy metabolism reactions in tumors. Accordingly, anti‐tumor nanodrugs targeting the disruption of this abnormal redox homeostasis have become one of the hot spots in the field...

The integration of one‐selector‐one‐resistor crossbar arrays requires the selectors featured with high nonlinearity and bipolarity to prevent leakage currents and any crosstalk among distinct cells. However, a selector with sufficient nonlinearity especially in the frame of device miniaturization remains scarce, restricting the advance of high‐density storage devices. Herein, a high‐performance memory...
