The battery performance declines significantly in severely cold areas, especially discharge capacity and cycle life, which is the most significant pain point for new energy consumers. To address this issue and improve the low‐temperature characteristic of aluminum‐ion batteries, in this work, polydopamine‐derived N‐doped carbon nanospheres are utilized to modify the most promising graphite material...
The dendrite growth and parasitic reactions that occur on Zn metal anode (ZMA)/electrolyte interface hinder the development of aqueous zinc ion batteries (AZIBs) in next‐generation renewable energy storage systems. Fortunately, reconstructing the inner Helmholtz layer (IHL) by introducing an electrolyte additive, is viewed as one of the most promising strategies to harvest the stable ZMA. Herein,...
The electrochemical dinitrogen (N2) reduction reaction (NRR) under ambient conditions has gained significant interest as an environmentally friendly alternative to the traditional Haber–Bosch process for the synthesis of ammonia (NH3). However, up to now, most of the reported NRR electrocatalysts with satisfactory catalytic activities have been hindered by the large overpotential in N2 activation...
Creating single‐molecule junctions with a long‐lived lifetime at room temperature is an open challenge. Finding simple and efficient approaches to increase the durability of single‐molecule junction is also of practical value in molecular electronics. Here it is shown that a flexible gold‐coated nanopipette electrode can be utilized in scanning tunneling microscope (STM) break‐junction measurements...
Organic–inorganic hybrid perovskites have been considered as promising gain materials for lasing. Despite previous reports of lasing from nanocrystals, thin films and single crystals, the stability of perovskite lasers has been a challenge for its practical applications. Herein, a scalable strategy to prepare ultrastable perovskite@polymer hybrid fibers by employing a facile emulsion electrospinning...
Sustainable and cascade anticancer strategies have attracted great attention due to their excellent therapeutic performance. In article number 2000897, Fu‐Gen Wu and co‐workers present a self‐amplified nanoreactor for cancer treatment. The nanoreactor can convert oxygen into HO• for chemodynamic therapy, consume glucose for starvation therapy, and provide a hypoxic environment for hypoxia‐activated...
Fenton reaction‐mediated chemodynamic therapy (CDT) can kill cancer cells via the conversion of H2O2 to highly toxic HO•. However, problems such as insufficient H2O2 levels in the tumor tissue and low Fenton reaction efficiency severely limit the performance of CDT. Here, the prodrug tirapazamine (TPZ)‐loaded human serum albumin (HSA)–glucose oxidase (GOx) mixture is prepared and modified with a metal–polyphenol...
Flexible energy storage electronics have gained increasing attention in recent years, but the simultaneous acquiring of high volumetric and high areal capacities as well as excellent flexibility in order to truly implement wearable and portable electronics in practice remains challenging. Here, a conductive and highly deformable freestanding all‐pseudocapacitive paper electrode (Ti3C2Tx/MnO2 NWs)...
To guarantee the normal operation of next generation portable electronics and wearable devices, together with avoiding electromagnetic wave pollution, it is urgent to find a material possessing flexibility, ultrahigh conductive, and superb electromagnetic interference shielding effectiveness (EMI SE) simultaneously. In this work, inspired by a building bricks toy with the interlock system, we design...
Aligning PbZr0.52Ti0.48O3 (PZT) nanowires in polydimethylsiloxane introduces dielectrophoresis, improving the electromechanical properties of nanogenerators, and the light transmittance of composite films. A novel transparent and antipeep piezoelectric nanogenerator is developed that can be used for harvesting the energy from the light tapping of a finger on a cell phone, with an output current of...
