Natural environments and suicide mortality in the Netherlands: a cross-sectional, ecological study [PDF]

open access: yes, 2018
Background: Natural outdoor environments, such as green spaces (ie, grass, forests, or parks), blue spaces (ie, visible bodies of fresh or salt water), and coastal proximity, have been increasingly shown to promote mental health.

Engineering Relative Spatial Structure of Dual Atomic Sites with Asymmetric Coordination for High‐Performance Hydrogen Evolution Activity

open access: yesAdvanced Functional Materials, EarlyView.
Dual‐atom catalysts featuring varying spatial configurations of metal sites (Pt1Fe1 DACs) are employed to systematically investigate the influence of spatial arrangements on the electronic structure and catalytic activity of active sites. Notably, the 3D asymmetric Pt1Fe1‐TAC dimer, featuring strong interatomic interactions, demonstrates superior ...

The dawn of urbanity

open access: yesCity, Territory and Architecture
Contemporary urban transformations are increasingly challenging the traditional categories through which the urban has been conceptualized, highlighting the need for a critical reinterpretation of its origins.

Trends in the Payoff to Academic and Occupation-Specific Skills: the Short and Medium Run Returns to Academic and Vocational High School Courses for Non-College Bound Students [PDF]

open access: yes, 1998
Using data from three longitudinal surveys of American high school students, I show that vocational courses helped non-college-bound-students to start their work life more successfully, in terms of steadier employment, higher wages and higher earnings. A

Upcycling of Disposable Face Masks into Water‐Resistant and Flame Retardant Foams

open access: yesAdvanced Functional Materials, EarlyView.
Disposable mask waste is upcycled into lightweight polypropylene‐based foams with tunable porosity and composite architectures reinforced by ear‐loop fibers. The sustainable solvent‐based process enables upcycling rates of 91% and solvent recovery of >90%.

MIGRATION, URBANIZATION AND SENSE OF URBANITY: THE SAMPLE OF KIRIKKALE

open access: yesZeitschrift für die Welt der Türken, 2016
Sense of urbanity is a concept that expresses how much do people living in a particular urban geography care about or internalize the culture of the city, whether, in this respect, they adopted the specific attitudes and behaviours of the city they live

Rural Urbanity and Rural Metropolises as Emerging Patterns of Urban Growth [PDF]

open access: yes
The processes of metropolitanization must explain if and how they concern some specific areas, how and if they primarily concern networks, hubs and nodes, pushing into the background the immediate territories of the metropolis. We assume that small-sized

Is compact urbanity more connected? [PDF]

open access: yes, 2016
The concept of urban compactness is widely accepted as an approach in modern architectural and urban design fields, this belief may vary relative to the density and connectivity of various neighborhoods working within cities of developing countries ...

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

open access: yesAdvanced 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 ...
