Study on the complex relationship of tourism-economy-ecological environment in arid zones: the case of Xinjiang, China

The synergistic integration of tourism, the economy, and the ecological environment within a region is crucial for promoting its sustainable development. Tourism acts as a catalyst for green economic growth, yet varying levels of tourism development can intensify the strain on the ecological environment. Thus, achieving a Pareto optimal balance among the benefits of these three entities holds significant theoretical and practical relevance. This research utilizes statistical data spanning from 2000 to 2021 to devise a tourism-economy-ecological environment (TEE) indicator system for Xinjiang. The study employs a coupled coordination model to analyze the spatial and temporal coupling dynamics between subsystems and to classify the types of coupled coordination. The analysis also identifies obstacles that impede the degree of coordination. The findings indicate that during the period under investigation, the TEE system in Xinjiang experienced consistent growth. However, the tourism subsystem exhibited disparate development and pronounced resource monopolization, which stimulated the economic subsystem’s growth, albeit with noticeable developmental lags in the latter stages. Spatially, economic performance demonstrated a declining trend from core urban centers like Urumqi City and Karamay City towards peripheral areas. From an ecological perspective, the distribution of resources exhibited a heterogeneous “M-V-W” pattern, characterized by significant disparities in the availability of natural resources and the occurrence of localized ecological deterioration. There is a notable and increasing degree of coupled coordination in regional synergistic development, which is primarily manifested in the delayed development of tourism. The combined development of the three subsystems is influenced by some factors, including environmental pollution, resources, economic quality, and industrial structure. Soot emissions, green space per capita in parks, and sulfur dioxide emissions are identified as key constraints. This study provides theoretical backing and empirical evidence for economic growth, the optimization of industrial structure, and the preservation of the ecological environment in arid and semi-arid regions globally.

Tripartite synergy: Photodegradation of congo red and bromothymol blue with concurrent bacterial photoinhibition using ZnCe/Bi2Mn2O6/rGO nanocomposites

The present research studies show the multidimensional characteristics of ZnCe/Bi2Mn2O6/rGO nanostructures for photocatalytic degradation of bromothymol blue (BTB), Congo red (CR) and photoinhibition of E. coli and S. aureus. A new solvothermal protocol was applied for the synthesis of ZnCe/Bi2Mn2O6/rGO nanomaterial. Important analytical techniques were applied for the characterization of the said nanomaterials. When allowed to visible light, the said nanostructure demonstrated excellent photocatalytic degradation of both the said dyes. The findings revealed that almost 99 % of both dyes were eliminated in just 30 min. In the absence of light, there was less than 60 % decline in both dyes even after 100 min. The ZnCe/Bi2Mn2O6/rGO was tested multiple times against the said dyes, and after seven cycles, its efficiency was reduced by only 15 %. Moreover, the nanostructures exhibited promising antibacterial properties by inducing photoinhibition of both E. coli and S. aureus bacteria. The inhibition zones of ZnCe/Bi2Mn2O6/rGO under visible light irradiation were measured to be approximately 17 ± 0.2 mm against E. coli and 19 ± 0.3 mm against S. aureus. These nanostructures effectively impeded bacterial growth and viability, underscoring their potential for applications in water disinfection and as antibacterial coatings. They are promising options for a variety of applications, especially as catalysts in many industries, due to their non-toxic nature and thermal stability. This work presents fascinating avenues for further investigation into the application of nanocomposites in healthcare and environmental preservation.

Visual and Gravimetric CO2 Sensing at High Humidity Levels Enabled by MOF‐804 Cofunctionalized with Ionic Liquid and m‐Cresol Purple

AbstractReal‐time monitoring of carbon dioxide (CO2) is imperative for medical diagnosis and effective environmental preservation. Despite the formidable challenge posed by the inherent chemical inertness of CO₂ molecules, a pioneering CO2 sensor based on MOF‐804 cofunctionalized with ionic liquid (IL) and m‐cresol purple (mCP) is successfully developed. By ingeniously integrating hydrogen bonding, electrostatic interactions, and hydrophobic properties within the sensitive layer, the sensor achieves a state‐of‐the‐art sensitivity (Δf = 384 Hz), an exceptionally vast detection range spanning 400–80 000 ppm, and remarkable stability with minimal sensitivity drift even at relative humidity (RH) levels exceeding 80%. Furthermore, the inherent gasochromic property, stemming from the zwitterionic mechanism, paves the way for innovative self‐sustaining CO2 test strips and groundbreaking applications, including CO2 tracking and CO2‐encrypted security labeling technology. Collectively, the realization of this ultra‐sensitive and robust CO2 monitoring approach, coupled with its CO2‐triggered visual and multifunctional capabilities, opens up novel avenues for dynamic CO2 detection, advanced military encryption strategies, and enhanced health management systems.

Experiential value and environmentally responsible behavioral intention in rock-climbing tourism: The role of place attachment and biospheric value

With increasing emphasis on environmental issues in outdoor leisure tourism, understanding the environmentally responsible behavioral intention (ERBI) of tourists is crucial to sustainable development. We explored the novel chain-mediating effect of experiential value on ERBI through place attachment and biospheric value among 300 recreational climbers in Yangshuo County, Guilin City. Using confirmatory factor analysis (CFA) and structural equation modeling (SEM), we found that the experiential value of climbing resorts had a direct effect on place attachment and biospheric value. Experiential value and place attachment had a moderate effect on ERBI, while biospheric value had a positive effect on ERBI. However, experiential value and place attachment indirectly influenced ERBI through the mediating effect of biospheric value. Finally, experiential value indirectly affected ERBI via the chain-mediating effects of place attachment and biospheric value. These findings extend existing theoretical frameworks by elucidating previously underexplored chain-mediation relationships. Practical insights derived from this study include strategies for enhancing the management and environmental protection of rock-climbing resorts. These strategies should focus on deepening the emotional connection between recreational climbers and the environment through innovative marketing approaches that emphasize tailored environmental protection activities, community involvement, and sustainable tourism practices. Management implicationsThe findings suggest three innovative strategies, building on existing practices, to foster sustainable tourism in rock-climbing resorts by connecting tourists with the environment. First, immersive programs such as ecotourism, wildlife observation, and multimedia experiences would enhance experiential value. These programs can promote environmentally responsible behavior by actively engaging tourists in environmental education and encouraging deeper interactions with nature, fostering place attachment and biospheric values.

ANÁLISE DO COMPORTAMENTO EROSIVO E CARACTERIZAÇÃO SEDIMENTOLÓGICA DA BARRA ARENOSA NA FOZ DO RIO ITABAPOANA, PRESIDENTE KENNEDY-ES

The state of Espírito Santo, despite being the smallest in the Southeast region, presents a significant diversity in the variations between the effects of retrogradation and coastal progradation. This dynamic is influenced by a complex interplay of variable factors, such as coastal geomorphology, hydrodynamics, and geology, which directly affect coastal cities and their development. The objectives of this study are to understand the phenomenon of coastal erosion and to analyze the morphological behavior of the sandy bar at the mouth of the Itabapoana River and at Praia das Neves, generating relevant information for the preservation of the coastal environment and minimizing material losses in urban areas adjacent to the sea. This work used tools such as the Ground Penetrating Radar (GPR) for the interpretation of radarfacies, as well as remote sensing and satellite image geoprocessing methodologies, combined with sedimentological characterization studies applied to Environmental Geology. The integration of GPR data revealed a complex sedimentary dynamic, with reflectors that indicate the progradation of beach deposits, as well as eolian, fluvial and marine influences, observing the presence of filled paleochannels and fluvial deposits. The analysis of satellite images allowed us to identify variations in the morphology of the beach and the location of the sandy bar at the mouth of the Itabapoana River, which shows migration patterns in a north-south direction. The compilation of the results suggests that coastal erosion in the region is cyclical, alternating between moments of progradation and retrogradation throughout the analyzed period, reflecting a complex coastal environment that involves climatic factors and marine and fluvial dynamics. The sediments analyzed were well selected, ranging from fine to medium fraction, with heavy fine sediments from the Araçuaí-Ribeira Orogen, showing low textural maturity.

Proposals for Next-Generation Eco-Friendly Non-Flammable Refrigerants for a −100 °C Semiconductor Etching Chiller Based on 4E (Energy, Exergy, Environmental, and Exergoeconomic) Analysis

Recent advancements in cryogenic etching, characterized by high aspect ratios and etching rates, address the growing demand for enhanced performance and reduced power consumption in electronics. To precisely maintain the temperature under high loads, the cascade mixed-refrigerant cycle (CMRC) is predominantly used. However, most refrigerants currently used in semiconductor cryogenic etching have high global warming potential (GWP). This study introduces a −100 °C chiller using a mixed refrigerant (MR) with a GWP of 150 or less, aiming to comply with stricter environmental standards and contribute to environmental preservation. The optimal configuration for the CMRC was determined based on a previously established methodology for selecting the best MR configuration. Comprehensive analyses—energy, exergy, environmental, and exergoeconomic—were conducted on the data obtained using Matlab simulations to evaluate the feasibility of replacing conventional refrigerants. The results reveal that using eco-friendly MRs increases the coefficient of performance by 52%, enabling a reduction in compressor size due to significantly decreased discharge volumes. The exergy analysis indicated a 16.41% improvement in efficiency and a substantial decrease in exergy destruction. The environmental analysis demonstrated that eco-friendly MRs could reduce carbon emissions by 60%. Economically, the evaporator and condenser accounted for over 70% of the total exergy costs in all cases, with a 52.44% reduction in exergy costs when using eco-friendly MRs. This study highlights the potential for eco-friendly refrigerants to be integrated into semiconductor cryogenic etching processes, responding effectively to environmental regulations in the cryogenic sector.

This study presents a facile approach to develop a recyclable and thermally-induced healing polyurea (PU)/graphene platelet (GNP) nanocomposites with high mechanical properties. A straightforward synthesis method was employed using isophorone diamine (IPDA) as chain extender with rigid cyclic structure. GNPs were modified with IPDA before adding into PU, showing remarkable enhancements in mechanical performance. At 0.10 wt.% GNPs, PU nanocomposites exhibited the maximum mechanical properties, with modified GNPs (M-GNPs) significantly outperforming pristine GNPs. Specifically, the tensile strength of PU increased by 41.3 % with M-GNPs, compared to only 12 % with pristine GNPs, underscoring the critical role of modifying the reinforcing phase. Furthermore, the nanocomposites demonstrated outstanding healing capabilities, achieving 89 % healing efficiency after 24 h at 120 °C. In addition, PU/M-GNP nanocomposites showed exceptional resistance to acidic and alkaline environments in comparison to neat PU. The study not only exemplifies developing high-strength and environmentally friendly materials but also holds promise for diverse applications, including aerospace, vibration damping, and protective coatings.
