Biodegradable and Recyclable Luminescent Mixed‐Matrix‐Membranes, Hydrogels, and Cryogels based on Nanoscale Metal‐Organic Frameworks and Biopolymers

Advanced Functional Materials, EarlyView.
The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...

A GloVe Model for Urban Functional Area Identification Considering Nonlinear Spatial Relationships between Points of Interest

ISPRS International Journal of Geo-Information, 2022
As cities continue to grow, the functions of urban areas change and problems arise from previously constructed urban planning schemes. Hence, the actual distribution of urban functional areas needs to be confirmed.

Social Cohesion of Functional Urban Areas (Example of Eastern Poland)

Social Indicators Research, 2023
AbstractThis paper is about studying social cohesion in functional urban areas (FUA). These territorial units become an important stakeholder and recipient of urban policy. Therefore, it is important to study problems of their development, including social cohesion. In the paper it is understood in spatial terms, i.e. it occurs when the differentiation

Bio‐Inspired Molecular Events in Poly(Ionic Liquids)

Advanced Functional Materials, EarlyView.
Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...

Spatial Differentiation of Warming Effects in Urban Functional Areas Based on Warming Sensitivity Indices

Redai dili
The POI data and Place2vec model within the third ring of Fuzhou City were used to identify the functional zones in the city, on the basis of which we were able to analyze the characteristics of the spatial differentiation of the thermal field levels in ...

Classification of Urban Functional Zones Based on Multiple Data Sources [PDF]

E3S Web of Conferences
With the rapid development of cities, more and more people are flocking to them. Therefore, cities require good planning to meet the needs of all urban residents. The first step in planning a city is to classify the functional areas of the city.

A stigmergy-based analysis of city hotspots to discover trends and anomalies in urban transportation usage

, 2018
A key aspect of a sustainable urban transportation system is the effectiveness of transportation policies. To be effective, a policy has to consider a broad range of elements, such as pollution emission, traffic flow, and human mobility.

Spin‐Dependent Generation of Surface‐Bound Radicals Toward Selective and Long‐Lasting Water Purification

Advanced Functional Materials, EarlyView.
This study develops a novel atomic engineering strategy to fine‐tune the spin state of α‐Fe2O3 catalysts toward a medium‐spin state, thereby modulating peroxymonosulfate activation and selectively yielding surface‐bound radicals. Compared with free radicals, surface‐bound radicals exhibit moderated oxidation potential, extended lifespan, surface ...

Urban heat island mitigation by green infrastructure in European Functional Urban Areas

Sustainable Cities and Society, 2022
The Urban Heat Island (UHI) effect is one of the most harmful environmental hazards for urban dwellers. Climate change is expected to increase the intensity of the UHI effect. In this context, the implementation of Urban Green Infrastructure (UGI) can partially reduce UHI intensity, promoting a resilient urban environment and contributing to climate ...
