Traditional villages, rich in historical and cultural value, hold a high level of preservation value. In the process urbanization, traditional villages face crisis decline, making it difficult to perpetuate carried heritage. The Ganjiang River Basin hosts numerous with research study their development this region significant topic. This paper, from perspective landscape ecology, employs geographic detectors analyze driving factors behind emergence Basin, summarizing spatial distribution...

Abstract The composition and configuration of landscapes are critical important to design effective approaches mitigate urban thermal environment in the urbanization process. In this research, land use maps surface temperature (LST) retrieval were derived Nanchang city central China based on product datasets infrared band Landsat. results showed that had become worse over past two decades, is, proportion area extremely low zone (ELTZ) decreased from 4.39 0.77% 2001 2020, medium (MTZ) reduced...

Hakka traditional villages are an important segment of Chinese villages. Analysis the process selection a site can deepen our knowledge culture. In this study, we selected in Fujian, Guangdong, and Jiangxi provinces as research sites. We extracted basic data for these using geographic information system coordinates, identified several potential influencing factors, analyzed correlations among factors R language. Finally, degree influence each factor on study area was determined probe to...

Abstract The assessment of landscape visual quality (LVQ) holds significant importance in the preservation and advancement traditional villages. One challenge measuring human perception lies establishing a connection between public preferences characteristics. This study conducted an analysis social media data from Anyi villages China to address this issue identified eight perceptions: naturalness, ancientness, colorfulness, variety, uniqueness, ingenuity, vividness, pleasantness. A total...

With the rapid development of artificial intelligence technology, an increasing number village-related modeling problems have been addressed. However, first, exploration watershed fine-grained classification problems, particularly multi-view problem, has hindered by dataset collection limitations; Second, networks typically employ convolutional modules for attentional to extract salient features, yet they lack global feature capabilities; Lastly, extensive parameters and significant...

Zeolitic membranes have been an active area of research for at least 25 years. Continuous and creative improvements in the materials chemistry membrane synthesis understanding predictability diffusion separations achieved. Activity continues unabated has increased with introduction new compositions such as metal-organic frameworks other to field. The economics implementing today's best zeolitic achievable systems are approaching commercial attractiveness, but many significant challenges...

Cellulose-based membrane materials allow for separations in both aqueous solutions and organic solvents. The addition of nanocomposites into cellulose structure is facilitated through steric interaction strong hydrogen bonding with the hydroxy groups present within cellulose. An ionic liquid, 1-ethyl-3-methylimidazolium acetate, was used as a solvent microcrystalline to incorporate graphene oxide quantum dots membranes. In this work, other composite such as, iron nanoparticles, polyacrylic...

Challenges associated with water separation technologies for per- and polyfluoroalkyl substances (PFASs) require efficient sustainable processes supported by a proper understanding of the mechanisms. The solute rejections nanofiltration (NF) at pH values near membrane isoelectric point were compared to size- mass-transfer-dependent modeled rejection rates these compounds in an ionized state. We find that low p

Ancient villages are a unique landscape of cultural heritage with both tangible and intangible culture, which provide rich ecosystem services for human beings. Assessment society’s perceptions on landscapes can improve the integration values into decision-making processes that affect landscapes, thereby contributing to maximizing benefits people receive from services. Based this premise, new sense-based hierarchical assessment framework ancient in China perspectives experts public was...

Metal−organic frameworks (MOFs) have been constructed from the reaction of Si(C6H4CO2H)4 and Ge(C6H4CO2H)4 with Zn(II). The two structures are quite different each other, both that known MOF C(C6H4CO2H)4 zinc portion carbon system is a dinuclear zinc-oxo cluster square-planar geometry, silicon consists chains containing atoms geometries, germanium linear clusters three geometries. For system, secondary building unit around distorted tetrahedron, whereas for bipyramid eight coordination....

A novel kind of soluble ladderlike poly(phenylsilsesquioxane) (LPPS) was prepared by stepwise coupling polymerization. Various techniques, such as fluorescence spectroscopy, X-ray diffraction (XRD), molecular simulation and calculation, were combined to indicate that the steric structure in LPPS predominantly cis-isotactic. It is anticipated polymerization a useful synthetic method for preparing poly(silsesquioxane)s with cis-isotactic structure, which have potential applications functional...

We have prepared a new family of periodic hybrid polymers containing microporous cavities provided by covalently bound organic hosts. Cyclodextrin (CD) or calixarene (CX) hosts are attached to four more trialkoxysilyl groups, which polymerized form polysilsesquioxane matrix. Structural integrity is copolymerization with tetraethoxysilane, produces polysilicate co-matrix. Periodic order created carrying out the polymerization in presence surfactant, cetyltrimethylammonium bromide. The...

Mesoporous titanium dioxide (TiO2) materials have been synthesized by a novel simple, template-free synthetic approach, which was carried out via nitric acid-catalyzed hydrolysis and polycondensation reactions of titanium(IV) n-butoxide. The as-prepared calcinated mesoporous TiO2 are characterized X-ray diffraction (XRD), transmission electron microscope (TEM), N2 adsorption/desorption measurements. amorphous possesses high BET surface area 470 m2 g−1 pore volume 0.28 cm3 g−1. After...
