Despite incorporation of organic groups into silica‐based aerogels to enhance their mechanical flexibility, the wide temperature reliability of the modified silicone aerogel is inevitably degraded. Therefore, facile synthesis of soft silicone aerogels with wide‐temperature stability remains challenging. Herein, novel silicone aerogels containing a high content of Si are reported by using polydimethylvinylsiloxane...
Achieving longitudinal doping of specific ions by surface treatment remains a challenge for perovskite solar cells, which are often limited by dopant and solvent compatibility. Here, with the flowing environment created by CsBr colloidal nanocrystals, ion exchange is induced on the surface of the perovskite film to enable the homogeneous distribution of Cs+ and gradient distribution of Br− simultaneously...

Silica nanofiber aerogels functionalized P(VDF‐HFP) membrane (SFP membrane), inspired by constructional engineering is constructed. As the host material for thermal comfort management and versatile protection, the SFP membrane features a large surface area, porous structure, and a robust skeleton that can render excellent mechanical properties. Additionally, the...
In recent years, growing concerns regarding energy efficiency and heat mitigation, along with the critical goal of carbon neutrality, have drawn human attention to the zero‐energy‐consumption cooling technique. Passive daytime radiative cooling (PDRC) can be an invaluable tool for combating climate change by dispersing ambient heat directly into outer space instead of just transferring it across the...
High‐capacity anode materials (e.g., Si) are highly needed for high energy density battery systems, but they usually suffer from low initial coulombic efficiency (CE), short cycle life, and low‐rate capability caused by large volume changes during the charge and discharge process. Here, a novel dendrimer‐based binder for boosting the electrochemical performance of Si anodes is developed. The polyamidoamine...
Defects, such as unsaturated coordination centers and vacancies, can fundamentally change materials’ inherent properties and growth habits. The development of defect engineering has promoted the application of many technologies, but it is still a great challenge to selectively manufacture defect sites in existing material systems. It is shown here that in situ site‐directed tailoring of metal sites...
It is a substantial challenge to construct electrocatalysts with high activity, good selectivity, and long‐term stability for electrocatalytic reduction of carbon dioxide to formic acid. Herein, bismuth and indium species are innovatively integrated into a uniform heterogeneous spherical structure by a neoteric quasi‐microemulsion method, and a novel C@In2O3@Bi50 core‐shell structure is constructed...
With the rapid development of artificial intelligence and neural network computing, the requirement for information storage in computing is gradually increasing. Floating gate memories based on 2D materials has outstanding characteristics such as non‐volatility, optical writing, and optical storage, suitable for application in photonic in‐memory computing chips. Notably, the optoelectronic memory...
For next‐generation Internet‐of‐Everything applications, for example, artificial‐neural‐network image sensors, artificial retina, visible light communication, on‐chip light interconnection, and flexible devices, etc., high‐performance microscale photodetectors are in urgent demands. 2D material (2DM) photodetectors have been researched and demonstrated impressive performances. However, they have not...
Rational engineering of the surface properties of perovskite nanocrystals (PeNCs) is critical to obtain light emitters with simultaneous high photoluminescence efficiency and excellent charge transport properties for light‐emitting diodes (LEDs). However, the commonly used lead halide sources make it hard to rationally optimize the surface compositions of the PeNCs. In addition, previously developed...
Semiconductor quantum dots (QDs) are among the most promising next‐generation optoelectronic materials. QDs are generally obtained through either epitaxial or colloidal growth and carry the promise for solution‐processed high‐performance optoelectronic devices such as light‐emitting diodes (LEDs), solar cells, etc. Herein, a straightforward approach to synthesize perovskite QDs and demonstrate their...
Transcription factor EB (TFEB) is a master regulator of autophagy and lysosomal biogenesis. Here, silver nanoparticles (Ag NPs)‐induced cytoprotective autophagy required TFEB is shown. Ag NPs‐induced nucleus translocation of TFEB through a well‐established mechanism involving dephosphorylation of TFEB at serine‐142 and serine‐211 but independent of both the mTORC1 and ERK1/2 pathways. TFEB nucleus...
