As an emerging two‐dimensional semiconductor, rhenium disulfide (ReS2) is renowned for its strong in‐plane anisotropy in electrical, optical, and thermal properties. In contrast to the electrical, optical, optoelectrical, and thermal anisotropies that are extensively studied in ReS2, experimental characterization of mechanical properties has largely remained elusive. Here, it is demonstrated that...
Due to the rapid growth in the demand for high‐energy‐density Lithium (Li) batteries and insufficient global Li reserves, the anode‐free Li metal batteries are receiving increasing attention. Various strategies, such as surface modification and structural design of copper (Cu) current collectors, have been proposed to stabilize the anode‐free Li metal batteries. Unfortunately, the mechanism of Li...
Superhard Nanocrystalline Cubic Silicon Carbide
In article number 2201212, Guoying Gao, Bo Xu, and co‐workers successfully synthesize nanocrystalline β‐SiC bulks with asymptotic Vickers hardness over the superhard threshold of 40 GPa, broadening the family of superhard materials. The frontispiece emphasizes the superhardness of nanocrystalline SiC bulk by scratching the cBN single crystal.
Superhard materials other than diamond and cubic boron nitride have been actively pursued in the past two decades. Cubic silicon carbide, i.e., β‐SiC, is a well‐known hard material with typical hardness <30 GPa. Although nanostructuring has been proven to be effective in enhancing materials’ hardness by virtue of the Hall–Petch effect, it remains a significant challenge to improve hardness of β‐SiC...
2D organic crystals exhibit efficient charge transport and field‐effect characteristics, making them promising candidates for high‐performance nanoelectronics. However, the strong Fermi level pinning (FLP) effect and large Schottky barrier between organic semiconductors and metals largely limit device performance. Herein, by carrying out temperature‐dependent transport and Kelvin probe force microscopy...
Flexible microfluidic systems have potential in wearable and implantable medical applications. Directional liquid transportation in these systems typically requires mechanical pumps, gas tanks, and magnetic actuators. Herein, an alternative strategy is presented for light‐directed liquid manipulation in flexible bilayer microtubes, which are composed of a commercially available supporting layer and...
Water control has always been essential from ancient times to modern life. The Chinese mythical hero, Da Yu, established a flood control system for the Yellow River and successfully protected the Chinese civilization. In article number 1901847, Yanlei Yu and co‐workers develop a strategy for light‐directed liquid manipulation in a flexible photodeformable microchannel, offering a novel concept of...
