The design and synthesis of novel two‐dimensional (2D) materials that possess robust structural stability and unusual physical properties may open up enormous opportunities for device and engineering applications. Herein, a 2D sumanene lattice that can be regarded as a derivative of the conventional Kagome lattice is proposed. The tight‐binding analysis demonstrates sumanene lattice contains two sets...
A compact, stable, sustainable, and high‐energy density power supply system is crucial for the engineering deployment of mobile electromechanical devices/systems either at the small‐ or large‐scale. This work proposes a spiral‐based mechanical energy storage scheme utilizing the newly synthesized 2D diamane. Atomistic simulations show that diamane spiral can achieve a high theoretical gravimetric...
Energy Storage
In article number 2203887, Haifei Zhan, Gang Zhang, Chaofeng Lü, and co‐workers propose a 2D diamane‐based planar spiral as an alternative low‐carbon footage energy supplier for micro‐/nano‐scale devices/systems based on its mechanical deformation. Supported by the theoretical analysis, atomistic investigations reveal that its gravimetric energy density can reach 2.03 MJ kg−1 or 564...
Edge Reconstruction
An unprecedented U‐edge reconstruction with the lowest energy is revealed to occur easily in the bilayer phosphorene. Such U‐edge reconstruction exhibits unexpectedly ultrafast electronic and thermal transport, nearly without edgeless scattering. More information can be found in article number 2105130 by Junfeng Gao, Gang Zhang, and co‐workers.
Edge termination plays a vital role in determining the properties of 2D materials. By performing compelling ab initio simulations, a lowest‐energy U‐edge [ZZ(U)] reconstruction is revealed in the bilayer phosphorene. Such reconstruction reduces 60% edge energy compared with the pristine one and occurs almost without an energy barrier, implying it should be the dominating edge in reality. The electronic...
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.
High‐performance black phosphorus n‐type field‐effect transistors are realized using Al adatoms as effective electron donors, which achieved a record high mobility of >1495 cm2 V−1 s−1 at 260 K. The electron mobility is corroborated to charged‐impurity scattering at low temperature, whilst metallic‐like conduction is observed at high gate bias with increased carrier density due to enhanced electron–phonon...
