Metaverse tourism is blurring the boundaries between the virtual and physical worlds. Among the core technologies in the metaverse world (e.g., Avatar, Virtual reality, Augmented reality, NFTs, etc.), the avatar has the potential power to revolutionise customer experience. Destination management organisation (DMO) can boost customers’ immersion through effective avatar customer journey design (ACJD) in the metaverse world. Yet, there is a lack understanding of how practitioners view an effective ACJD in the metaverse world. This study aims to explore the role of avatars on customer journey design in a metaverse tourism program (e.g., Dunhuang) from practitioners’ perspectives through a qualitative study. This study advances theoretical understanding about metaverse tourism in the tourism literature, and provides important implications for tourism industry on how to design tourist experiences in metaverse tourism.

How to effectively deal with the polluted water by the pollutant of organic dyes is the world problem. It is of great significance if the organic dyes in the polluted water can be directly turned into the useful materials through a facile approach. Herein, the water which contains the common organic dye, Reactive red 2 (RR2), has been chosen to be the model to synthesize graphene quantum dots (GQDs) by a facile route. The comprehensive characterizations, including TEM (HRTEM), XPS, Raman, PL and UV–Vis. spectra, have been performed to confirm the structures and explore the properties of the synthesized GQDs. Meanwhile, the excellent PL properties and low biotoxicity of the GQDs confer them with the potential applications in the biological fields. When the GQDs are excited by the wavelength of 360 nm, the maximum emission is achieved at 428 nm. It is well demonstrated that the synthesized GQDs are able to detect the Al3+ which causes multiple diseases, such as Parkinson, Alzheimer, kidney disease, and even cancer. The detection range is from 90 to 800 μM, which is different from the reported kinds of the literature. Therefore, this work not only provides an economical and environmental route on solving the universal problem from organic dyes, but also facilitates to advancing the synthesis and application of GQDs.

RCEP will have a significant impact on ASEAN, China and other contracting parties, significantly enhancing the cooperative levels between ASEAN and other essential economies in the region. It can develop the manufacturing industry in ASEAN and China with higher quality. First of all, this study used the Strengths (S), Weaknesses (W), Opportunities (O) and Threats (T) (SWOT) model to analyze the specific impacts of China’s participation in RCEP on the development of ASEAN’s manufacturing industry. Subsequently, strategic recommendations were put forward for the high-quality development of ASEAN’s manufacturing industry under the RCEP cooperation mechanism from four aspects of SO,WO, ST and WT. As the signing of RCEP provides an excellent development opportunity, the ASEAN member countries should carry out deeper cooperation with China; create new strengths for high-quality development of the manufacturing industry; erect a closer regional industrial chain and the supply chain; and promote the realization of a higher level of regional economic integration between ASEAN and China.

Since the Western Zhou dynasty in China, the word 聖人began to have a special meaning, entered various social fields such as literature and history and medicine, and gradually integrated into Chinese traditional culture. As an important symbol of traditional Chinese medicine culture, 聖人 shows a basic category of the core concept and value system of traditional Chinese medical classics represented by the book of Huangdi Neijing(also named The Inner Canon of Huangdi) in the pre-Qin and Han dynasties. In Huangdi Neijing which is the foundation work of the theoretical system of traditional Chinese medicine, 聖人is not only a man with perfect personality under the traditional Chinese moral and ethical concepts, but also a regimen practitioner and a master of universe laws and the best model of physical and mental health. Based on the traditional Chinese medicine book Huangdi Neijing, this paper uses the knowledge of Chinese philology and traditional Chinese medicine culture to trace the origin meaning of the Chinese word 聖人 from the perspective of genesis, and examines the semantic evolution of 聖人 and its cultural characteristics in the development of the Chinese nation and the Traditional Chinese medicine

A composite photocatalyst of zinc oxide (ZnO) nanoparticles decorated with different content of reduced graphene oxide (rGO) was prepared via a simple and facile one-step method in this paper. X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Raman spectra, and UV–Vis diffuse reflection spectroscopy (UV–Vis DRS) were used to characterize the crystal structure, morphology and optical properties of the rGO–ZnO composite photocatalyst. The photocatalytic properties of the composites were investigated using methyl orange (MO), a typical orange compound, as a test pollutant. The results showed that rGO–ZnO composites displayed significantly enhanced photocatalytic activity in MO degradation than pure ZnO, and the pseudo-first-order kinetic constant on the optimal rGO–ZnO composite was 14 times as great as that on pure ZnO. The enhanced photocatalytic ability of the rGO-ZnO composites was mainly benefited from the high specific surface area and high conductivity of rGO, which facilitated efficient charge separation in the rGO-ZnO nanocomposite.

Molybdenum disulfide ( MoS2) has been one of the most promising members of transition-metal dichalcogenides materials. Attributed to the excellent electrical performance and special physical properties, MoS2 has been broadly applied in semiconductor devices, such as field effect transistors (FETs). At present, the exploration of further improving the performance of MoS2- based FETs (such as increasing the carrier mobility and scaling) has encountered a bottleneck, and the application of high-κ gate dielectrics has become an effective approach to change this situation. Atomic layer deposition (ALD) enables high-quality integration of MoS2 and high-κ gate dielectrics at the atomic level. In this review, we summarize recent advances in the fabrication of two-dimensional MoS2 FETs using ALD high-κ materials as gate dielectrics. We first briefly discuss the research background of MoS2 FETs. Second, we expound the electrical and other essential properties of high-κ gate dielectrics, which are essential to the performance of MoS2 FETs. Finally, we focus on the advances in fabricating MoS2 FETs with ALD high-κ gate dielectrics on MoS2, as well as the optimized ALD processes. In addition, we also look forward to the development prospect of this field.

The hybridization of graphene with magnetic nanoparticles has endowed graphene with increasing interest as the adsorbent for wastewater treatment. However, its fabrication often involves a multi-stepped chemical synthesis process. In this work, we demonstrate a facile, one-step, and solvent-free approach to fabricate Fe3O4 nanoparticle-anchored Laser-Induced Graphene ( Fe3O4@LIG) as an efficient adsorbent by direct laser irradiation on a ferric acetylacetonate containing polybenzoxazine film. Raman and X-ray diffraction analysis confirm the graphene component in the adsorbent, and the morphology characterizations show that Fe3O4 nanoparticles are distributed uniformly on LIG with hierarchical meso- and macro-porous structures. Adsorption experiments indicate that Fe3O4@ LIG can adsorb methylene blue (MB) from aqueous solutions in a fast and effective manner, with a maximum adsorption capacity up to 350.9 mg/g. The adsorption kinetics and isotherms are also investigated, which are well-described by the pseudo-second-order model and Langmuir model, respectively. Additionally, Fe3O4@ LIG is also demonstrated with the efficient removal of a variety of organic solvents from water. The favorable adsorption behavior of Fe3O4@ LIG is attributed to its unique porous structure and the molecular interactions with adsorbates. On the other hand, Fe3O4@ LIG has high magnetic property, and therefore, it could be easily recovered from water and well regenerated for repeated use. With the efficient adsorption of organic pollutants, magnetic separability, and good

Besides, the adsorption capacity of tetracycline could reach 678.19 mg/g, the adsorption processes agreed well with the pseudo-second-order kinetic model and Langmuir isotherm model.

The intrinsic negative Poisson’s ratio effect at the level of molecule in two-dimensional nanomaterials, especially in the perfect planar nanostructures with a single atom thickness, is really rare and has attracted a lot of research interests because of its unique mechanical properties in the nanoscale and extensive applications in mechanical nanodevices. In this work, a novel ideal planar carbon nanostructure (PCNS) framework with a single atom thickness composed by carbon and hydrogen atoms is proposed and studied by means of first-principles density functional calculation. The results showed that the PCNS is, simultaneously, of excellent thermodynamic, molecular dynamic and mechanical stabilities. In addition, the electronic structure, mechanical characters, and optical-electronic characteristics of PCNS are also explored. Excitedly, it is found that the PCNS has a significant negative Poisson’s ratio effect in plane, and the maximum value of Poisson’s ratio is as high as − 2.094. Meanwhile, the material has a wide range of elastic mechanics. Moreover, the PCNS presents an ideal UV absorption performance. It is hoped that this work could be a useful structural design strategy for the development of the ideal 2D carbon-based nanomechanical devices with the intrinsic negative Poisson’s ratio effect and other electronic functions.

진정한 의미에서의 민간예술작품에서 구현하는 것은 겉면에 표출된 화려한 표상할 뿐만 아니라 그 내면을 탐구하는 것, 더욱 이런 예술 풍격을 단조해 낸 불굴의 민족의식과 정감이다. 예로부터 사회의 발전과 계급 분화로 원시 예술의 변천을 거쳐 분리되어 형성된 문인예술, 궁정예술, 종교예술, 민간예술에 이르기까지 이러한 다른 관념을 기반으로 한 예술 문화 종류가 역사의 흐름 속에서 갈등하고 또 끊임없이 서로 연계하며 기반으로 하고 모순, 연계와 융합에서 하나의 완전한 민족 문화를 육성하였다. 오늘에 이르기까지 민간예술문화에서의 순수한 예술 신념은 여전히 줄곧 이른바 고상하고 우아한 예술 문화에 대해 확고한 기초적 역할을 하고있다. 수암만족 민간 전지(剪紙)는 동북 백산흑수사이에 만족 노동 인민이 창조한 역사적 예술 문화의 완벽한 결정체일 뿐만아니라 또한 수암의 전통적 만족 민간 예술 특유한 민족 예술문화 표식이고 동북 지역의 만족 의향 및 옥도 특색의 전통 민간예술의 걸출한 대표이다. 이것은 동북 만족 인민의 지혜의 예술을 포함하고 있으며 중요한 역사적 가치와 문화적 가치가 있을 뿐만 아니라 또한 중요한 예술적 가치와 과학적 가치를 지니고 있으며 전통문화의 결정체이자 화하문명의 보물이다. 지금은 어떤 의미에서 이미 문화브랜드로 된 민간 전지예술이 점차 문화의 수요품으로 되고 있다. 특유의 가치와 방식으로 문화가 널리 전파되는 또 다른 경로로 되고 있다. 그러나 북방 만족 전지를 놓고 말할 때 기나긴 과정에서 아주 많은 문제도 나타났다. 이를테면 제작 형식과 예술 풍격의 혼동, 관련 문화자료내용의 귀납 정리와 발전 전승 등이다. 본 논문은 북방 만족 문화의 대표 특징을 지닌 수암만족 전지를 연구 대상으로 지역 역사, 문화 신앙 등등 방면에 대해 중국 북방 만족 종이 오림이 형성된 근원성 원인을 심도 있게 분석하였다. 이와 동시에 종이 오림 작품이 드러낸 예술 상태에 있어서 다른 지역의 동류 작품들과 전체적 및 개별적 비교를 하여 예술풍격상의 지역문화 차이를 분명히했다. 또 현재를 결부시켜 전지 예술이 사람들에게 대한 의의를 서술하고 전통문화를 발전시키고 전승할 것을 호소했다.

The Dispute Settlement Mechanism of the World Trade Organization (WTO) is facing serious crisis, which has impeded its normal function. To address this impasse, this article suggests a reform of the WTO’s dispute-settlement mechanism: the establishment of a new megamultilateral court to substitute for the Appellate Body. The first part of this paper addresses the reasons for considering this approach. The second part identifies how to establish a new mega-multilateral court within the WTO. The third part puts forward an idea of the function of the Dispute Settlement Body, which would serve as a forum for adjudicators and State Parties of the mega-multilateral court, in order to balance judicial independence, judicial accountability, and consistency. In discussing the reason for this reform, approaches to implementing it, and other examples of what form it might take, this article concludes that it is appropriate to establish a new mega-multilateral court within the WTO.
