Performance assessment of a potential underground thermal storage facility: Case study of the closed mine Prosper‐Haniel in the Ruhr coal mining area in Germany

open access: yesDeep Underground Science and Engineering, EarlyView.
This study demonstrates the feasibility of an underground closed‐loop thermal storage facility at a post‐mining site, intended for seasonal heat energy storage. Its principal design shows water flow directions in winter and summer (1, 2), heat pumps (3), an upper water reservoir (4), and connecting pipes (5).

Combining paleoecology and modeling to explore cascading disturbances in forest ecosystems

open access: yesEcography, EarlyView.
Climate‐induced cascading disturbance interactions pose a major challenge to the sustainable provision of forest ecosystem services to society. Developing a deeper understanding and enhanced capacity to simulate these interactions is essential for identifying disturbance‐induced tipping points in forest ecosystems, and for improving management in ...

The conceptual design changes triggered by timber boards [PDF]

open access: yes, 2011
After the introduction of timber boards as diaphragms in light-frame construction opened the way to modern timber construction, three major design changes would follow: the elements become multifunctional, they can work structurally in two directions ...

Bridging Policy Gaps in Transition Times: How Local Actors Navigate Low Policy Coherence for Advancing a Circular Built Environment

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT The construction sector is a major contributor to the climate crisis, accounting for over one‐third of global energy‐related CO2 emissions. In response, the European Commission identified the circular economy as a means of achieving green growth and prioritized the construction sector in its Circular Economy Action Plan.

Wood‐Derived 3D Conductive Cellular Bio‐C@YB2C2 Ceramics for Efficient Electromagnetic Shielding and Joule Heating

open access: yesElectron, EarlyView.
Herein, a biomimetic, anisotropic, robust wood‐derived 3D conductive Bio‐C@YB2C2 framework was synthesized by in situ boron/carbon thermal reduction reaction on the carbonized wood template. The as‐obtained Bio‐C@YB2C2 composites accurately inherit the specific microstructure of natural wood, providing pathways for terahertz wave dissipation.
