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...
Vascular Electrical Stimulations
Hong Li, Liming Yang, and co‐workers used battery‐free implants and surgically mounted them on the abdominal aorta of high‐fat‐fed ApoE‐/‐ mice, which were electrically stimulated using a wireless electrical stimulation device for four weeks to observe changes in atherosclerotic plaques. Direct vascular electrical stimulation has emerged as a promising therapeutic...
Electrical stimulation (ES) is a safe and effective procedure in clinical rehabilitation with few adverse effects. However, studies on ES for atherosclerosis (AS) are scarce because ES does not provide a long‐term intervention for chronic disease processes. Battery‐free implants and surgically mounted them in the abdominal aorta of high‐fat‐fed Apolipoprotein E (ApoE−/−) mice are used, which are electrically...
The development of high‐efficiency enzyme mimics is of great significance in the field of biocatalysis. However, it remains challenging to design novel enzyme mimics with multiple enzyme‐like activities, excellent stability, and good reusability. Herein, a facile molecular assembly strategy to construct dialdehyde cellulose (DAC) templated Cu‐doped polydopamine (DAC@PDA/Cu) membrane with dual enzyme‐like...
In this work, Fe–Ni alloy nanoclusters (Fe–Ni ANCs) anchored on N, S co‐doped carbon aerogel (Fe–Ni ANC@NSCA catalysts) are successfully prepared by the optimal pyrolysis of polyaniline (PANI) aerogels derived from the freeze‐drying of PANI hydrogel obtained by the polymerization of aniline monomers in the co‐presence of tannic acid (TA), Fe3+, and Ni2+ ions. In addition, the optimal molar ratio of...
Phototherapy in the second near‐IR (1000–1700 nm, NIR‐II) window has achieved much progress because of its high efficiency and relatively minor side effects. In this paper, a new NIR‐II responsive hollow magnetite nanocluster (HMNC) for targeted and imaging‐guided cancer therapy is reported. The HMNC not only provides a hollow cavity for drug loading but also serves as a contrast agent for tumor‐targeted...
Herein, water‐dispersible carbon nano‐onion clusters (CNOCs) with an average hydrodynamic size of ≈90 nm are prepared by simply sonicating candle soot in a mixture of oxidizing acid. The obtained CNOCs have high photothermal conversion efficiency (57.5%), excellent aqueous dispersibility (stable in water for more than a year without precipitation), and benign biocompatibility. After polyethylenimine...
Combining photothermal therapy (PTT) with clinical technology to kill cancer via overcoming the low tumor targeting and poor therapy efficiency has great potential in basic and clinical researches. A brand‐new MoS2 nanostructure is designed and fabricated, i.e., layered MoS2 hollow spheres (LMHSs) with strong absorption in near‐infrared region (NIR) and high photothermal conversion efficiency via...
