Chemical mechanical polishing (CMP) offers a promising pathway to smooth third‐generation semiconductors. However, it is still a challenge to reduce the use of additional oxidants or/and energy in current CMP processes. Here, a new and green atomically smoothing method: Piezocatalytic‐CMP (Piezo‐CMP) is reported. Investigation shows that the Piezo‐CMP based on tetragonal BaTiO3 (t‐BT) can polish the...
Nanozymes with peroxidase‐mimic activity have recently emerged as effective strategies for eliminating infections. However, challenges in enhancing catalytic activities and the ability to target bacteria have hindered the broader application of nanozymes in bacterial infections. Herein, a novel nanozyme based on mesoporous CeO2 nanosphere and meso‐tetra(4‐carboxyphenyl)porphine (TCPP) encapsulated...
It has been well‐established that light‐matter interactions, as manifested by diverse linear and nonlinear optical (NLO) processes, are mediated by real and virtual particles, such as electrons, phonons, and excitons. Polarons, often regarded as electrons dressed by phonons, are known to contribute to exotic behaviors of solids, from superconductivity to photocatalysis, while their role in materials’...
Shelter forests (or shelter‐belts), while crucial for climate regulation, lack monitoring systems, e.g., Internet of Things (IoT) devices, but their abundant wind energy can potentially power these devices using the trees as mounting points. To harness wind energy, an omnidirectional fluid‐induced vibration triboelectric nanogenerator (OFIV‐TENG) has been developed. The device is installed on shelter...
Chronic diabetic wounds remain a worldwide challenge for both the clinic and research. Given the vicious circle of oxidative stress and inflammatory response as well as the impaired angiogenesis of the diabetic wound tissues, the wound healing process is disturbed and poorly responds to the current treatments. In this work, a nickel‐based metal‐organic framework (MOF, Ni‐HHTP) with excellent antioxidant...
Tailoring nanoparticles’ composition and morphology is of particular interest for improving their performance for catalysis. A challenge of this approach is that the nanoparticles’ optimized initial structure often changes during use. Visualizing the three dimensional (3D) structural transformation in situ is therefore critical, but often prohibitively difficult experimentally. Although electron tomography...
The patient‐centered healthcare requires timely disease diagnosis and prognostic assessment, calling for individualized physiological monitoring. To assess the postoperative hemodynamic status of patients, implantable blood flow monitoring devices are highly expected to deliver real time, long‐term, sensitive, and reliable hemodynamic signals, which can accurately reflect multiple physiological conditions...
Robust, ultrathin, and environmental‐friendliness papers that synergize high‐efficiency electromagnetic interference (EMI) shielding, personal thermal management, and wearable heaters are essential for next‐generation smart wearable devices.

In particular, 2D SbI3 is first experimentally...
Nature provides a successful evolutionary direction for single‐celled organisms to solve complex problems and complete survival tasks – pseudopodium. Amoeba, a unicellular protozoan, can produce temporary pseudopods in any direction by controlling the directional flow of protoplasm to perform important life activities such as environmental sensing, motility, predation, and excretion. However, creating...
The pathological aggregation of some proteins is claimed to be highly related to several human diseases, such as β‐amyloid 1–42 (Aβ42) to Alzheimer's disease (AD), islet amyloid polypeptide, and insulin to type 2 diabetes mellitus. Therefore, it is in desperate need to develop effective methods for detection of protein aggregates and inhibition of abnormal aggregation. Herein, to construct all‐in‐one...
