Liquid Crystal Structure of Supercooled Liquid Gallium and Eutectic Gallium–Indium

The existence of liquid crystal (LC) mesophase in metallic materials is counterintuitive. Typical LCs are made of covalently bonded organic molecules. This study reports on the observation of LC mesophases in supercooled liquid gallium and eutectic gallium–indium alloy. LC texture of the lamellar structure similar to that of the smectic phase is unveiled...

Increasing Accessible Subsurface to Improving Rate Capability and Cycling Stability of Sodium‐Ion Batteries

Heteroatom doping affects the interlayer spacing of subsurface region much more than bulk for carbonaceous nanoparticles. The increased accessible subsurface boosts the pseudocapacitive capacity and endows SRNDC-700 with excellent rate performance up to 50 A g−1. This varies from diffusion-controlled capacity determinism and provides a novel design...

Ultrastrong and Ductile Soft Magnetic High‐Entropy Alloys via Coherent Ordered Nanoprecipitates

Ultrastrong and ductile bulk high-entropy alloys with excellent soft magnetic properties are achieved by introducing a high volume fraction of coherent and ordered nanoprecipitates into the alloy matrix. The high lattice coherency between the homogeneously dispersed nanoprecipitates and the alloy matrix creates only negligible distortion fields on magnetic...

Crystallization by Amorphous Particle Attachment: On the Evolution of Texture

It is shown that biogenic minerals not only provide key in-sight into material morphogenesis during crystallization by amorphous particle attachment but also teach us fundamental new mechanisms that have a profound effect on textural evolution during non-classical crystal growth. A link between the emergence of texture and amorphous particle accretion...

A Universal Strategy toward the Precise Regulation of Initial Coulombic Efficiency of Li‐Rich Mn‐Based Cathode Materials

The introduced cation/anion double defects can reduce the interface charge transfer resistance and enhance the Li+ ions diffusion coefficient. The induced in situ surface reconstruction layer can increase the electronic conductivity and stabilize the surface lattice oxygen. As a result, the initial Coulombic efficiency of Li-rich Mn-based cathode material...

3D Laser Displays Based on Circularly Polarized Lasing from Cholesteric Liquid Crystal Arrays

Full-color 3D laser displays are demonstrated on cholesteric liquid crystal arrays, which comprise two sets of red–green–blue (RGB) pixels to present two images with orthogonal circularly polarized laser emissions. Stereoscopic images can be generated in a viewer's mind by fusing the two images acquired by the left and right eyes, respectively. ...
