The imbalance of charge injection is considered to be a major factor that limits the device performance of cadmium‐free quantum‐dot light‐emitting diodes (QLEDs). In this work, high‐performance cadmium‐free Cu─In─Zn─S(CIZS)‐based QLEDs are designed and fabricated through tailoring interfacial energy level alignment and improving the balance of charge injection. This is achieved by introducing a bilayered...
Reducing non‐radiative recombination energy loss (ΔEnonrad) in organic solar cells (OSCs) has been considered an effective method to improve device efficiency. In this study, the backbone of PTBTT‐4F/4Cl is divided into D1‐D2‐D3 segments and reconstructed. The isomerized TPBTT‐4F/4Cl obtains stronger intramolecular charge transfer (ICT), thus leading to elevated highest occupied molecular orbital...
Polymer‐based solid electrolytes (PSEs) offer great promise in developing lithium metal batteries due to their attractive features such as safety, light weight, low cost, and high processability. However, a PSE‐based lithium battery usually requires a relatively high temperature (60 °C or above) to complete charge and discharge due to the poor ionic conductivity of PSEs. Herein, a gel polymer electrolytes...

In article number 2106352, Fei Chen, Ben Bin Xu, and co‐workers develop a gel polymer electrolyte (GPE) with a supramolecular crosslinked structure and quadruple hydrogen bonding to fulfill a GPE with high thermal stability, good mechanical property and a high ionic conductivity of 3.8 × 10−3 S cm−1 at 25 °C. This work encompasses a route to develop high performance electrolyte...
In vivo mineralization is a multistep process involving mineral‐protein complexes and various metastable compounds in vertebrates. In this complex process, the minerals produced in the mitochondrial matrix play a critical role in initiating extracellular mineralization. However, the functional mechanisms of the mitochondrial minerals are still a mystery. Herein, an in vitro enzymatic reaction strategy...
In article number 1804321, Ying‐Jie Zhu, Zheng‐Dong Cai, Feng Chen, and co‐workers report an enzymatic reaction strategy for the generation of biomimic nanominerals. The results provide in vitro evidence for the effect of ATP on the formation and stabilization of the biomineral, and demonstrate a potential strategy for the preparation of the biomimic mineral for treating bone related diseases.
Efficient utilization of abundant solar energy for clean water generation is considered a sustainable and environment friendly approach to mitigate the global water crisis. For this purpose, this study reports a flexible fire‐resistant photothermal paper by combining carbon nanotubes (CNTs) and fire‐resistant inorganic paper based on ultralong hydroxyapatite nanowires (HNs) for efficient solar energy‐driven...
