River ecosystem metabolism and carbon biogeochemistry in a changing world

Tom Ian Battin, Enrico Bertuzzo, Luis Gómez Gener

River networks represent the largest biogeochemical nexus between the continents, ocean and atmosphere. Our current understanding of the role of rivers in the global carbon cycle remains limited, which makes it difficult to predict how global change may al ...

Polar oceans and sea ice in a changing climate

Julia Schmale, Hélène Paule Angot, Jenny Thomas

Polar oceans and sea ice cover 15% of the Earth’s ocean surface, and the environment is changing rapidly at both poles. Improving knowledge on the interactions between the atmospheric and oceanic realms in the polar regions, a Surface Ocean–Lower Atmospher ...

Reuse of concrete components in new construction projects: Critical review of 77 circular precedents

Corentin Jean Dominique Fivet, Maléna Bastien Masse, Célia Marine Küpfer

Extracting pieces of concrete from obsolete buildings and reusing them, as is, in new assemblies is today rarely considered a strategy for improving the sustainability of the construction sector. By delaying the crushing of concrete into aggregates and avo ...

Novel low-temperature fiber sensing technique using Brillouin scattering in gas

Luc Thévenaz, Yuting Yang, Marcelo Alfonso Soto Hernandez

Brillouin scattering in gases shows the unique property to offer an enhanced temperature sensitivity at very low temperatures. This attractive solution for cryogenic systems is justified theoretically and validated experimentally. ...

Climatic and Ecological Impact of Greenlandic Glacial Outwash Plains

Devis Tuia, Julia Schmale, Nora Bergner, Ianina Altshuler, Gaston Jean Lenczner, Grace Emma Marsh

Warming in the Arctic is occurring at an accelerated rate compared to the rest of the world which is partially driven by ecological and climatic feedback loops. Accelerated glacial and ice sheet retreat in Greenland drives increased development of glacial ...

Low-tech methods for the reuse of reinforced concrete structural elements

Corentin Jean Dominique Fivet, Maléna Bastien Masse, Nicole Widmer, Julie Rachel Devènes

Most of existing buildings are made of concrete, new buildings are being built with it and others are demolished when still in good structural condition. This drives increased demands for raw materials, greenhouse gas emissions, and an accumulation of demo ...

Photovoltaics at multi-terawatt scale: Waiting is not an option

Sophia Haussener, Stefaan De Wolf

A major renewable-energy milestone occurred in 2022: Photovoltaics (PV) exceeded a global installed capacity of 1 TWdc. But despite considerable growth and cost reduction over time, PV is still a small part of global electricity generation (4 to 5% for 202 ...

Decision support methodology for waste-to-value process integration

Rafael Amorim Leandro De Castro Amoedo

Waste treatment is a complex procedure that comprises multidimensional aspects. The challenges posed by the energy transition and international protocols emphasize the role of waste in its material and energy dimension. With an increasing population and li ...

Low ozone dry deposition rates to sea ice during the MOSAiC field campaign: Implications for the Arctic boundary layer ozone budget

Julia Schmale, Ivo Fabio Beck, Hélène Paule Angot

Dry deposition to the surface is one of the main removal pathways of tropospheric ozone (O3). We quantified for the first time the impact of O3 deposition to the Arctic sea ice on the planetary boundary layer (PBL) O3 concentration and budget using year-ro ...

Divertor detachment and reattachment with mixed impurity seeding on ASDEX Upgrade

Using newly developed spectroscopic models to measure the divertor concentration of Ne and Ar, it is shown that the experimental detachment threshold on ASDEX Upgrade with Ar-only and mixtures of Ar+N or Ne+N scales as expected in comparison with an analyt ...
