The preservation and accessibility of pores are prerequisites to the application of metal–organic frameworks (MOFs). Activation is a key step to eliciting rich features of pores, but it needs a repeated solvent‐exchange process which is tedious and time/cost‐consuming. Herein, a facile strategy for highly‐efficient activation of MOFs utilizing rotating packed bed is proposed. With the tremendous enhancement...
Bioinspired smart superwetting surfaces with special wettability have aroused great attention from fundamental research to technological applications including self‐cleaning, oil–water separation, anti‐icing/corrosion/fogging, drag reduction, cell engineering, liquid manipulation, and so on. However, most of the reported smart superwetting surfaces switch their wettability by reversibly changing surface...
Thin‐film lithium niobate platform, namely lithium‐niobate‐on‐insulator (LNOI), brings new opportunities for integrated photonics, taking advantages from both outstanding crystalline properties and special structural features. The excellent properties of LNOI have triggered development of a variety of on‐chip photonic devices for light generation and manipulation. However, as an indispensable component...
LNOI‐Based Photodetectors
In article number 2203532, Yuechen Jia, Feng Chen, and co‐workers propose a subtle framework to realize self‐powered lithium niobite photodetectors by encapsulating both Ag nanoparticles and ions into LNOI thin film. The Ag ion implantation not only leads to the encapsulated Ag nanoparticles in the LNOI to enhance the photoelectric response of photovoltaic material, but also...
The high capacity of Li‐rich and Mn‐based (LRM) cathode materials is originally due to the unique hybrid anion‐ and cation redox, which also induces detrimental oxygen escape. Furthermore, the counter diffusion of released oxygen (into electrolyte) and induced oxygen vacancies (into the interior bulk phase) that occurs at the interface will cause uncontrolled phase collapse and other issues. Therefore,...
The surface Fermi level pinning effect promotes the formation of metal‐independent Ohmic contacts for the high‐speed GaSb nanowires (NWs) electronic devices, however, it limits next‐generation optoelectronic devices. In this work, lead‐free all‐inorganic perovskites with broad bandgaps and low work functions are adopted to decorate the surfaces of GaSb NWs, demonstrating the success in the construction...
Specific recognition and strong affinities of bacteria receptors with the host cell glycoconjugates pave the way to control the bacteria aggregation and kill bacteria.

The 2D layered materials are promising candidates for broadband, low‐cost photodetectors. One deficiency of 2D materials is the relatively low absorbance of light, limiting the applications of the 2D photodetectors. Doping of plasmonic nanoparticles into 2D materials may enhance the optical absorbance owing to the localized surface plasmonic resonance (LSPR) effect; however, considerable defects may...

The sulfur vacancies generated by the ion irradiation result in the one‐way electron transport from the...

Under excitation of a femtosecond laser, the ultrafast dynamic response of the nanostructure is tailored through the scattering mechanism at the interface between Cu and Ag nanoparticle layers...
Traditional liquid marbles (LMs), liquid droplets encapsulated by hydrophobic particles at the liquid–gas interface, are restricted by their short lifetime and low heat transfer efficiency. Herein, a new paradigm for LMs immersed in various liquid mediums with massive enhanced heat transfer and spatial recognition is designed; without compromising the structural integrity, the lifetime of the liquid...
In vivo mineralization is a multistep process involving mineral‐protein complexes and various metastable compounds in vertebrates.

While electroporation has been widely used as a physical method for gene transfection in vitro and in vivo, its application in gene therapy of cardiovascular cells remains challenging. Due to the high concentration of ion‐transport proteins in the sarcolemma, conventional electroporation of primary cardiomyocytes tends to cause ion‐channel activation and abnormal ion flux, resulting in low transfection...
