Although bioactive compounds (BCs) have many important functions, their applications are greatly limited due to their own defects. The development of nanocarriers (NCs) technology has gradually overcome the defects of BCs. NCs are equally important as BCs to some extent. Self‐assembly (SA) methods to build NCs have many advantages than chemical methods, and SA has significant impact on the structure...

The chemical inertness of CO2 molecules makes their adsorption and activation on a catalyst surface one of the key challenges in recycling CO2 into chemical fuels. However, the traditional template synthesis and chemical modification strategies used to tackle this problem face severe structural collapse and modifier deactivation issues during the often‐needed post‐processing procedure. Herein, a CO...
Iron oxide nanoparticles are a kind of important biomedical nanomaterials.

To change the binary structure of nanotube and nanotube array in vertically aligned carbon nanotube arrays, this work deposits regularly arranged amorphous alumina sheets on the classical array growth catalyst (10 nm‐thick alumina and 2 nm‐thick iron) and obtains an array similar to the Medusa head. Subsequent experiments revealed that these alumina sheets show both unstable and stable qualities during...
Terahertz Spectroscopy
In article number 2306200, Tao Zhao, Tianwu Wang, Guangyou Fang, and co‐workers generated broadband terahertz pulses by dual‐color laser‐induced air plasma. Subsequently, the interaction between terahertz waves and MXene reveals the localized charge carrier effects caused by electron‐phonon scattering. In the image, ‘e’ and ‘p’ represent electrons and phonons, respectively,...
The transport properties of charge carriers in MXene, a promising material, have been studied using terahertz time‐domain spectroscopy (THz‐TDS) to examine its potential applications in optical and electronic devices. However, previous studies have been limited by narrow frequency ranges, which have hindered the understanding of the intrinsic mechanisms of carrier transport in MXenes. To address this...
As an essential component of future full‐color displays, blue perovskite light‐emitting diodes (PeLEDs) still lag far behind the red and green counterparts in the device performances. In the mainstream quasi‐2D blue perovskite system, trap‐mediated nonradiative loss, low energy transfer efficiency, and interface fluorescence quenching remain significant challenges. Herein, guanidinium thiocyanate...
Interface engineering attracted tremendous attention owing to its remarkable ability to impede dendrite growth and side reactions in aqueous zinc‐ion batteries. Artificial interface layers composed of crystalline materials have been extensively employed to stabilize the Zn anode.

With the rapid development of performance and long‐term stability, bismuth vanadate (BiVO4) has emerged as the preferred photoanode in photoelectrochemical tandem devices. Although state‐of‐the‐art BiVO4 photoanodes realize a saturated photocurrent density approaching the theoretical maximum, the fill factor (FF) is still inferior, pulling down the half‐cell applied bias photon‐to‐current efficiency...
Layered manganese‐based oxides (LMOs) are promising cathode materials for sodium‐ion batteries (SIBs) due to their versatile structures. However, the Jahn–Teller effect of Mn3+ induces severe distortion of MnO6 octahedra, and the resultant low symmetry is responsible for the gliding of MnO2 layers and then inferior multiple‐phase transitions upon Na+ extraction/insertion. Here, hexagonal P2‐Na0.643...
