Ultra‐thin 2D materials have great potential as electrodes for micro‐supercapacitors (MSCs) because of their facile ion transport channels. Here, a high‐precision controllable photonic‐synthesis strategy that provided 1 inch wafer‐scale ultra‐thin film arrays of alloyed WxMo2xSy with sulfur vacancies and expanded interlayer (13.2 Å, twice of 2H MoS2) is reported. This strategy regulates the nucleation and growth of transition metal dichalcogenides (TMDs) on the picosecond or even femtosecond scale, which induces Mo–W alloying, interlayer expansion, and sulfur loss. Therefore, the diffusion barrier of WxMo2xSy is reduced, with charge transfer and ion diffusion enhancing. The as‐prepared symmetric MSCs with the size of 100 × 100 µm2 achieve ultrahigh specific capacitance (242.57 mF cm−2 and 242567.83 F cm−3), and energy density (21.56 Wh cm−3 with power density of 485.13 W cm3). The established synthesis strategy fits numerous materials, which provides a universal method for the flexible synthesis of electrodes in microenergy devices. [ABSTRACT FROM AUTHOR]

Bailing capsule (BLC), a drug that is clinically administered to modulate the autoimmune system, exhibits promising therapeutic potential in the treatment of thyroiditis. This study elucidates the chemical profile of BLC and its potential therapeutic mechanism in thyroiditis, leveraging network pharmacology and molecular docking techniques. Utilizing ultra‐high‐performance liquid chromatography coupled with linear trap‐Orbitrap mass spectrometry (UHPLC‐LTQ‐Orbitrap MS), 58 compounds were identified, the majority of which were nucleosides and amino acids. Utilizing the ultra‐high‐performance liquid chromatography coupled with triple quadrupole tandem mass spectrometry (UHPLC QqQ MS/MS) strategy, 16 representative active components from six batches of BLCs were simultaneously determined. Network pharmacology analysis further revealed that the active components included 5′‐adenylate, guanosine, adenosine, cordycepin, inosine, 5′‐guanylic acid, and l‐lysine. Targets with higher connectivity included AKT1, MAPK3, RAC1, and PIK3CA. The signaling pathways primarily focused on thyroid hormone regulation and the Ras, PI3K/AKT, and MAPK pathways, all of which were intricately linked to inflammatory immunity and hormonal regulation. Molecular docking analysis corroborated the findings from network pharmacology, revealing that adenosine, guanosine, and cordycepin exhibited strong affinity toward AKT1, MAPK3, PIK3CA, and RAC1. Overall, this study successfully elucidated the material basis and preliminary mechanism underlying BLC's intervention in thyroiditis, thus laying a solid basis for further exploration of its in‐depth mechanisms.

Under the policy of cultural tourism integration, the huge economic and social benefits brought by night tourism are gradually recognized. Based on the compatibility, in response to the needs of cultural heritage protection and night tourism development in the Southwest Dong area, a driving mechanism for night tourism and cultural heritage live protection with the spirit of place as the core is proposed. Taking the Huangdu Dong Village in Hunan as an example, the research explored the traditional night culture of Dong Village, analysed the development status of night tourism, and proposed interactive development strategies for Dong Village night tourism and cultural heritage protection, which will help the destination resource allocation shift from space expansion to time expansion and accelerate its innovative development on the basis of the protection of the authenticity of cultural heritage. The research has certain reference significance for the survival of traditional culture and the innovative development of tourism in ethnic minority villages.

Healthy living space is the guarantee of high quality of life, dong Village is one of the few minority living space environment adaptation wisdom of the living carrier. By virtue of its healthy ecosystem and the smart wisdom of residents, it is connected with or adapted to the natural environment to create a healthy and livable living space under low-technology conditions. Taking The Gaoxiu Dong Village as the research object, this paper analyzes the environmental adaptation wisdom of the spatial elements such as road system, drum tower space and residential building in Gaoxiu Dong Village, so as to show the spatial form beauty, functional practical beauty and national characteristic beauty of Dong Village. From the perspective of health, it analyzes the adaptive form and mode of human living space, and inherits the wisdom of building with respect to nature and environment.

Molybdenum disulfide (MoS2)-based nanostructures are highly desirable for applications such as chemical and biological sensing, photo/electrochemical catalysis, and energy storage due to their unique physical and chemical properties. In this work, MoS2 core-shell nanoparticles were first prepared through the liquid-phase processing of bulk MoS2 by a femtosecond laser. The core of prepared nanoparticles was incompletely and weakly crystalline MoS2; the shell of prepared nanoparticles was highly crystalline MoS2, which wrapped around the core layer by layer. The femtosecond laser simultaneously achieved liquid-phase ablation and light exfoliation. The formation mechanism of the core-shell nanoparticles is to prepare the nanonuclei first by laser liquid-phase ablation and then the nanosheets by light exfoliation; the nanosheets will wrap the nanonuclei layer by layer through van der Waals forces to form core-shell nanoparticles. The MoS2 core-shell nanoparticles, because of Mo−S bond breakage and recombination, have high chemical activity for chemical catalysis. Afterward, the nanoparticles were used as a reducing agent to directly prepare three-dimensional (3D) Au-MoS2 micro/nanostructures, which were applied as surface-enhanced Raman spectroscopy (SERS) substrates to explore chemical sensing activity. The ultrahigh enhancement factor (1.06×1011), ultralow detection limit (10−13 M), and good SERS adaptability demonstrate highly sensitive SERS activity, great ability of ultralow concentration detection, and ability to detect diverse analytes, respectively. This work reveals the tremendous potential of 3D Au-MoS2 composite structures as excellent SERS substrates for chemical and biological sensing. [ABSTRACT FROM AUTHOR]

Component engineering and quantum confinement engineering approaches are commonly used to prepare blue perovskite quantum dots (PQDs). From a component engineering perspective, the hybrid halide (Br and Cl) perovskites can adequately perform bandgaptailoring and the as-obtained spectra could cover the entire blue light range. However, the mixed halide PQDs are prone to lattice mismatch and phase separation. In addition, the low formation energy of Cl vacancies in perovskites tends to form Cl vacancies within the band gap, leading to deeper defect energy levels and significantly nonradiative recombination. Small size PQDs with single halide (Br), such as CsPbBr3 with a size of ≈ 4 nm, exhibit pure blue emission due to quantum confinement effects, which can avoid the phase separation and the issue of Cl vacancies. However, current methods are difficult to form small quantum dots of uniform size, which results in a very wide linewidth. In this paper, a strategy is designed to accurately and controllably reduce the size of CsPbBr3 PQDs. With the post-treatment of the CsPbBr3 PQDs, the emitting color gradually changed from green to blue, and the QDs sizes are reduced from 12 nm to 3 nm. Finally, the PQDs exhibit the stable spectra with a range of 520 nm to 450 nm and highly reproducible PLQY of 60%. Correspondingly, the full width at half maximum （FWHM） is reduced from 27 nm to 15 nm. This strategy provides a new idea for the synthesis of blue-emitting PQDs and provides a research basis for further realization of efficient and stable PQDs and subsequent devices.
