The city, the urban, the place

GEOUSP: Espaço e Tempo (Online), 2006
Na Mesa Redonda "A Cidade, o Urbano, o Lugar", realizada no Encontro Internacional "O Mundo do Cidadão. Um Cidadão do Mundo" em homenagem ao professor Milton Santos, propus rever a utilização historicamente dada pelos autores que trabalharam com esses três conceitos que estão entre os mais importantes dentre os utilizados na geografia (embora não sejam

A Dual‐Functional Biohybrid Nanorobot to Synergistically Eradicate Biofilm and Degrade Antibiotic Resistance Genes

Advanced Science, EarlyView.
A biohybrid nanorobot integrating lytic bacteriophage N4 with Pd nanozymes is developed for targeted eradication of multidrug‐resistant E. coli biofilms. Synergistic bacterial lysis and ROS‐mediated oxidation enable simultaneous biofilm removal and antibiotic resistance genes degradation, maintaining high efficacy in complex wastewater environments ...

Random Walks Estimate Land Value

, 2010
Expected urban population doubling calls for a compelling theory of the city. Random walks and diffusions defined on spatial city graphs spot hidden areas of geographical isolation in the urban landscape going downhill.

Phase Fraction Modulation Enhances Li+/Na+ Diffusion Disparity in Spent LiFePO4 Cathodes for Efficient Lithium Extraction from Brine

Advanced Science, EarlyView.
A direct cascaded utilization strategy for spent LiFePO4 batteries efficiently extracts lithium from brine, embodying the “urban mining” concept. Phase fraction modulation revealed its significant impact on local bond lengths of crystal structure and the Li/Na diffusion energy barrier, identifying the best material (Li0.19FePO4) for lithium extraction.

African American male youth: An urban ethnography of race, space & place [PDF]

, 2013
Student migration within U.S. urban school districts is now a central feature of policies that promote school choice to access a quality education. Policymakers also support the value of diversity in public schools, even as educational policies and legal

Spatially Selective Solvation Chemistry by Local Charge Enrichment for Stable Potassium‐Metal Anodes

Advanced Science, EarlyView.
A MoC/NC functional intermediate medium preferentially interacts with KFSI to reconstruct the interfacial solvation structure and form a KF‐rich inorganic SEI. The synergistic integration of the electronically insulating SEI and MoC/NC suppresses electron tunneling, enables fast and balanced K+/electron transport, and promotes uniform K deposition for ...

Urban Design in Neighbourhood Commodification [PDF]

The intention to promote local economic development through place marketing and urban design based interventions is linked to the commodification of the city, a trend emerging parallel to a new milieu for intercity competition. The aim with this paper is

Bionic Solar‐Powered Heavy Metal Trap for Eco‐Friendly Sludge Drying and Simultaneous Electricity Generation

Advanced Science, EarlyView.
Herein, we propose a solar‐powered heavy metal trap (SPHT) for sludge disposal. The indoor experiments demonstrated that the sludge water content decreased from 90 % to 31 %, coupled with a decrease in heavy metal content to 6 % at most. Furthermore, the designed SPHT generated an initial potential of 0.10 V, and monitoring this hydrovoltaic potential ...

Giving urban policy its 'medical': assessing the place of health in area-based regeneration [PDF]

, 2006
How does regeneration affect health and how have successive urban policy evaluations sought to measure such impacts? This article draws on a systematic review of national-level evaluation documentation relating to government-funded, area-based ...

Metasurface‐Enabled Active‐Like Passive Radar

Advanced Science, EarlyView.
A programmable space‐time‐coding metasurface embeds distinct spatiotemporal tags into ambient wireless signals, allowing passive radar to operate in an active‐like manner. By enabling code‐correlated reconstruction under interference, the approach supports robust real‐time UAV tracking in complex environments and points to intelligent, low‐power ...
