Defects in ferroelectric materials have many implications on the material properties which, in most cases, are detrimental. However, engineering these defects can also create opportunities for property enhancement as well as for tailoring novel functionalities. To purposely manipulate these defects, a thorough knowledge of their spatial atomic arrangement, as well as elastic and electrostatic interactions...

Metal selenides (MSex) with high theoretical capacity and diverse species have aroused extensive interests. In article number 2206194, Yu Li, Ying Bai, Chuan Wu, and co‐workers comprehensively review the synthesis methods, modification strategies, sodium storage mechanism and recent research progress of various MSex. The effective utilization of MSex anodes will be beneficial...
In lithium ion batteries (LIBs), the layered cathode materials of composition LiNi1−x−yCoxMnyO2 are critical for achieving high energy densities. A high nickel content (>80%) provides an attractive balance between high energy density, long lifetime, and low cost. Consequently, Ni‐rich layered oxides cathode active materials (CAMs) are in high demand, and the importance of LiNiO2 (LNO) as limiting...
The acquired resistance to Osimertinib (AZD9291) greatly limits the clinical benefit of patients with non‐small cell lung cancer (NSCLC), whereas AZD9291‐resistant NSCLCs are prone to metastasis. It's challenging to overcome AZD9291 resistance and suppress metastasis of NSCLC simultaneously. Here, a nanocatalytic sensitizer (VF/S/A@CaP) is proposed to deliver Vitamin c (Vc)–Fe(II), si‐OTUB2, ASO‐MALAT1,...
The powerful and rapid development of lithium‐ion batteries (LIBs) in secondary batteries field makes lithium resources in short supply, leading to rising battery costs. Under the circumstances, sodium‐ion batteries (SIBs) with low cost, inexhaustible sodium reserves, and analogous work principle to LIBs, have evolved as one of the most anticipated candidates for large‐scale energy storage devices...
Atomic heating on single atoms (SAs) to maximize the catalytic efficiency of each active site would be a fascinating solution to break the bottleneck for the performance improvement of single‐atom catalysts (SACs) but highly challenging task. Here, based on the Gd@MoS2 SACs synthesized by a facile laser molecular beam epitaxy method, high‐frequency alternating magnetic field (AMF) technology is employed...
Electricity generation triggered by the ubiquitous water evaporation process provides an intriguing way to harvest energy from water. Meanwhile, natural water evaporation is also a fundamental way to obtain fresh water for human beings. Here, a wafer‐scale nanostructured silicon‐based device that takes advantage of its well‐aligned configuration that simultaneously realizes solar steam generation...
Immunotherapy aims to activate the cancer patient's immune system for cancer therapy. The whole process of the immune system against cancer referred to as the “cancer immunity cycle”, gives insight into how drugs can be designed to affect every step of the anticancer immune response. Cancer immunotherapy such as immune checkpoint inhibitor (ICI) therapy, cancer vaccines, as well as small molecule...
Exquisite design of RuO2‐based catalysts to simultaneously improve activity and stability under harsh conditions and reduce the Ru dosage is crucial for advancing energy conversion involving oxygen evolution reaction (OER). Herein, a distinctive cobalt‐doped RuOx framework is constructed on Co3O4 nanocones (Co3O4@CoRuOx) as a promising strategy to realize above urgent desires. Extensive experimental...
Lithium–sulfur (Li–S) batteries have attracted considerable attention owing to their extremely high energy densities. However, the application of Li–S batteries has been limited by low sulfur utilization, poor cycle stability, and low rate capability. Accelerating the rapid transformation of polysulfides is an effective approach for addressing these obstacles. In this study, a defect‐rich single‐atom...
Fibrous hydrogels are a key component of soft animal tissues. They support cellular functions and facilitate efficient mechanical communication between cells. Due to their nonlinear mechanical properties, fibrous materials display non‐trivial force propagation at the microscale, that is enhanced compared to that of linear‐elastic materials. In the body, tissues are constantly subjected to external...
Artificial assembly of organic–inorganic heterostructures for electrochemical energy storage at the molecular level is promising, but remains a great challenge.

Systematic characterizations reveal that PANI...
The interaction between platelets and circulating tumor cells (CTCs) contributes to distal tumor metastasis by protecting CTCs from immunological assault and shear stress, which can be disrupted by nitric oxide (NO) through inhibiting platelet‐mediated adhesion. To eradicate primitive tumors and inhibit CTC‐based pulmonary metastasis, a novel biomimetic nanomedicine (mCuMNO) is designed by encapsulating...
The construction of hollow metallic microspheres with rationally designed building blocks of the metal shell is a promising way to achieve low density and functionality control, but the microengineering of the metallic structures on a micrometer spherical surface is a great challenge. In the present work, a novel and simple calcination‐induced aggregation strategy is developed to realize the distribution...
The practical application of Li‐S batteries is seriously hindered due to its shuttle effect and sluggish redox reaction, which requires a better functional separator to solve the problems.

Micro‐sized silicon (µSi) anode features fewer interfacial side reactions and lower costs compared to nanosized silicon, and has higher commercial value when applied as a lithium‐ion battery (LIB) anode. However, the high localized stress generated during (de)lithiation causes electrode breakdown and performance deterioration of the µSi anode. In this work, hollow graphitic carbons with tailored dual...
Thrombotic diseases have a high rate of mortality and disability, and pose a serious threat to global public health.
