Contested densification: Sustainability, place and expectations at the urban fringe

open access: yesFrontiers in Sustainable Cities, 2022
The discourse of sustainability-by-density is dominant in urban policies and climate-friendly urbanism today. Yet, with current failures and disparities in the regulation of dense development and land speculation, the effects of such policies are not ...

Systematic review and comparison of densification effects and planning motivations

open access: yesBuildings and Cities, 2021
Do higher urban densities contribute to more sustainable cities and communities? This paper examines the effectiveness of higher density (as a means) for achieving sustainable urban development (the goal) following three lines of enquiry.

Densification of agro-residues for sustainable energy generation: an overview

open access: yesBioresources and Bioprocessing, 2021
The global demand for sustainable energy is increasing due to urbanization, industrialization, population, and developmental growth. Transforming the large quantities of biomass resources such as agro-residues/wastes could raise the energy supply and ...

Modelling the transition from grain-boundary sliding to power-law creep in dry snow densification [PDF]

open access: yes, 2022
This paper presents a physics-based macroscale model for the densification of dry snow which provides for a smooth transition between densification by grain-boundary sliding (stage 1) and densification by power-law creep (stage 2).

D'une densification subie à une densification collaborative?: Vécus comparés de la densification douce, Allemagne et France [PDF]

open access: yes, 2016
Soft densification takes place in suburban fabrics that are in transition due to operations conducted by inhabitants such as plot division, house division or built volume addition.

Improving the Conventional Pelletization Process to Save Energy during Biomass Densification

open access: yesBioResources, 2015
A pellet mill is currently the most frequently used method for producing pellets using either a ring die or a flat die. In the densification process, a great amount of energy is required to avoid spring-back and to overcome the friction between the ...

Densification and preservation of ceramic nanocrystalline character by spark plasma sintering [PDF]

open access: yes, 2012
Spark plasma sintering is a hot pressing technique where rapid heating by dc electric pulses is used simultaneously with applied pressure. Thus, spark plasma sintering is highly suitable for rapid densification of ceramic nanoparticles and preservation ...
