The Course of Physical Geography of Immanuel Kant (1724-1804) : the contribution for the geographical science history and the epistemology

open access: yesRevista Raega: O Espaço Geográfico em Análise, 2009
There is a relative weakness about our knowledge concerning Kant philosophy and the constitution of the modern geography and, consequently, the scientific one.

High‐Temperature Oxidation of the CrFeNi Medium‐Entropy Alloy

open access: yesAdvanced Engineering Materials, EarlyView.
The oxidation behavior of equiatomic CrFeNi MEA is a key issue that determines this material's suitability for high‐temperature application. The understanding of long‐term behavior is even more crucial than short‐term corrosion effects. The alloy is exposed to synthetic air at 1000, 1050, and 1100 °C for 24, 100, and 1000 h and systematically compared ...

Coupling Interfacial Redox‐Reactions with In Situ Proton Generation for the Photoelectrochemical Separation of Rare‐Earth Elements

open access: yesAdvanced Functional Materials, EarlyView.
To enhance the sustainability of electrochemical separations for resource recovery, a photoelectrochemical ion recovery system is developed that utilizes renewable solar energy. A composite integrating titianium dioxide nanorods and a redox‐copolymer enables spontaneous cation adsorption and light‐activated redox reactions for regeneration, thus ...

Brand Agriculture and Economic Geography: A General Equilibrium Analysis [PDF]

open access: yes
This paper presents a general equilibrium model of NEG incorporating the brand agriculture which produces differentiated agricultural products. Focusing on the core-periphery space, we show that highly differentiated brand agriculture can be sustained in

Understanding the Chemical and Electronic Properties of Sub‐Monolayer TiO2 on High Surface Area Silica for Jet Fuel Synthesis Applications

open access: yesAdvanced Functional Materials, EarlyView.
Sub‐monolayer titania grafted onto mesoporous silica enables solvent‐free photocatalytic upgrading of furfural and cyclopentanone into jet fuel precursors. Advanced spectroscopic methods reveal tunable surface speciation, acidity, and bandgaps, enhancing catalytic efficiency.

Economic Linkages Across Space [PDF]

open access: yes
We develop a diagrammatic framework that can be used to study the economic linkages between regions or cities. Hitherto, such linkages have not been the primary focus of either the theoretical or empirical literatures.

Living apart, losing sympathy? How neighbourhood context affects attitudes to redistribution and to welfare recipients [PDF]

open access: yes, 2013
Rising levels of income inequality have been directly linked to rising levels of spatial segregation. In this paper, we explore whether rising segregation may in turn erode support for the redistributive policies of the welfare state, further increasing ...

Atlas use in teaching geography in higher education in the U.S. and Canada

open access: yesČasopis Socìalʹno-Ekonomìčnoï Geografìï. Часопис соціально-економічної географії, 2017
Skills in map use and interpretation are important in geography education. Atlases represent special collections of maps that can be beneficial for developing map use and interpretation and spatial analysis skills in geography students. In this study, we

Perfusable Brain Microvascular Network‐On‐Chip Model to Study Flavivirus NS1‐Induced Endothelial Dysfunction

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a microfluidic brain microvascular network‐on‐chip (BMVasChip) to investigate endothelial barrier dysfunction caused by flavivirus non‐structural protein 1 (NS1), including virus‐ and time‐dependent vascular damage, leakiness, and dysfunction.
