Short‐wavelength infrared photodetectors play a significant role in various fields such as autonomous driving, military security, and biological medicine. However, state‐of‐the‐art short‐wavelength infrared photodetectors, such as InGaAs, require high‐temperature fabrication and heterogenous integration with complementary metal‐oxide‐semiconductor (CMOS) readout circuits (ROIC), resulting in a high...
Wide bandgap semiconductors, particularly In2O3:Sn (ITO), are widely used as transparent conductive electrodes in optoelectronic devices. Nevertheless, due to the strohave beenng scattering probability of high‐concentration oxygen vacancy (VO) defects, the mobility of ITO is always lower than 40 cm2 V−1 s−1. Recently, hydrogen‐doped In2O3 (In2O3:H) films have been proven to have high mobility (>100 cm...
The development of innovative and efficient Fe‐N‐C catalysts is crucial for the widespread application of zinc‐air batteries (ZABs), where the inherent oxygen reduction reaction (ORR) activity of Fe single‐atom sites needs to be optimized to meet the practical application. Herein, a three‐dimensional (3D) hollow hierarchical porous electrocatalyst (ZIF8@FePMPDA‐920) rich in asymmetric Fe‐N4‐OH moieties...
Disordered crystallization and poor phase stability of mixed halide perovskite films are still the main factors that compromise the performance of inverted wide bandgap (WBG; 1.77 eV) perovskite solar cells (PSCs). Great difficulties are evidenced due to the very different crystallization rates between I‐ and Br‐based perovskite components through DMSO‐alone assisted anti‐solvent process. Here, a...
Surface heterojunction has been regarded as an effective method to improve the device efficiency of perovskite solar cells. Nevertheless, the durability of different heterojunction under thermal stress is rarely investigated and compared. In this work, benzylammonium chloride and benzyltrimethylammonium chloride are utilized to construct 3D/2D and 3D/1D heterojunctions, respectively. A quaternized...
Garnet‐type solid electrolyte Li7La3Zr2O12 (LLZO) is widely considered as one of the most promising candidates for solid state batteries (SSBs) owing to its high ionic conductivity and good electrochemical stability. Since its discovery in 2007, great progress has been made in terms of crystal chemistry, chemical and electrochemical properties, and battery application. Nonetheless, reliable and controllable...
Two‐dimensional nanofluidic membranes offer great opportunities for developing efficient and robust devices for ionic/water‐nexus energy harvesting. However, low counterion concentration and long pathway through limited ionic flux restrict their output performance. Herein, it is demonstrated that rapid diffusion kinetics can be realized in two‐dimensional nanofluidic membranes by introducing in‐plane...
Biomimetic stimuli‐responsive structure colors (SCs) can improve the visualization and identification in the micro functional structure field such as information encryption/decryption and smart actuators. However, it is still challenging to develop the ability to 4D print arbitrary submerged colorful patterns with stimuli‐responsive materials at the microscale. Herein, a hydrogel photoresist with...
Lead selenide (PbSe) colloidal quantum dots (CQDs) are promising candidates for optoelectronic applications. To date, PbSe CQDs capped by halide ligands exhibit improved stability and solar cells using these CQDs as active layers have reported a remarkable power conversion efficiency (PCE) up to 10%. However, PbSe CQDs are more prone to oxidation, requiring delicate control over their processability...
As a promising therapeutic strategy against cancer, immunotherapy faces critical challenges, especially in solid tumors. Immune checkpoint blockade therapy, particularly blocking the interaction of the programmed cell death 1 (PD1)‐PD1 ligand 1 (PD‐L1) axis, can reverse the suppression of T cells so as to destroy tumor cells and exert antitumor effects. Here, a strategy of multiple activation of immune...
Infrared solar cells are regarded as candidates for expanding the solar spectrum of c‐Si cells, and the window electrodes are usually transparent conductive oxide (TCO) such as widely used indium tin oxide material. However, due to the low transmittance of the TCO in the near‐infrared region, most near‐infrared light cannot penetrate the electrode and be absorbed by the active layer. Here, the propose...
Inverted‐structure perovskite solar cells (PSCs) are known for their superior device stability. However, based on nickel‐oxide (NiOx) substrate, disordered crystallization and bottom interface instability of perovskite film are still the main factors that compromise the power conversion efficiency (PCE) of PSCs. Here, 2D perovskite of thiomorpholine 1,1‐dioxide lead iodide (Td2PbI4) is introduced...

In the tumor microenvironment (TME),...
Micromachines with high environmental adaptability have the potential to deliver targeted drugs in complex biological networks, such as digestive, neural, and vascular networks. However, the low processing efficiency and single processing material of current 4D printing methods often limit the development and application of shape‐morphing micromachines (SMMs). Here, two 4D printing strategies are...
Although incorporating multiple halogen (bromine) anions and alkali (rubidium) cations can improve the open‐circuit voltage (Voc) of perovskite solar cells (PSCs), severe voltage loss and poor stability have remained pivotal limitations to their further commercialization.
