In vivo X-ray microtomography locally affects stem radial growth with no immediate physiological impact

Pascal Turberg, Charlotte Grossiord, Laura Mekarni, Hervé Cochard

Microcomputed tomography (mu CT) is a nondestructive X-ray imaging method used in plant physiology to visualize in situ plant tissues that enables assessments of embolized xylem vessels. Whereas evidence for X-ray-induced cellular damage has been reported, ...

In situ nanoscale studies of copper-based catalysts for carbon dioxide electroreduction

Karla Banjac

The urgency of climate change demands the simultaneous removal of carbon dioxide from the atmosphere and the transition to renewable energy sources. This aim is realizable through electrochemical reduction of carbon dioxide (CO2RR), which is a promising ro ...

Developing a high capacity axis translation apparatus for gas shale testing

Lyesse Laloui, Alessio Ferrari, Jinwoo Kim

Gas shales are usually partially saturated due to hydrocarbon generation and often have a low in-situ degree of saturation less than 40 %. During stimulation, substantial fluid imbibition into the formation occurs due to high suction. Recent research on th ...

Earth and field observations underpin metapopulation dynamics in complex landscapes: Near-term study on carabids

Andrea Rinaldo, Damiano Pasetto, Francisco Javier Perez Saez, Jonathan Giezendanner

Understanding risks to biodiversity requires predictions of the spatial distribution of species adapting to changing ecosystems and, to that end, Earth observations integrating field surveys prove essential as they provide key numbers for assessing landsca ...

Palladium-Catalyzed Carbo-Oxygenation of Propargylic Amines using in Situ Tether Formation

Jérôme Waser, Phillip Gulliver Dominic Greenwood, Erwann Stefan Grenet

1,2-Amino alcohols and -aminocarbonyls are frequently found in natural products, drugs, chiral auxiliaries, and catalysts. This work reports a new method for the palladium-catalyzed oxyalkynylation and oxyarylation of propargylic amines. The reaction is pe ...

Strain-induced network chains damage in carbon black filled EPDM

Nicolas Candau, Oguzhan Oguz

This paper presents an experimental method to follow in-situ the chains network alteration of filled vulcanized rubbers induced by deformation. Macroscopic damage is first investigated on a series of EPDM by quantifying void fraction via Digital Image Corr ...

From observations to 3D forecasts: Data assimilation for high resolution lakes monitoring

Theo Baracchini

Lake mesoscale processes have no secrets for artists, they have some for scientists and policy-makers. In the introduction to this dissertation, we saw that poets and painters depict the lake with rich variability. This vision conflicts with conventional a ...

Fast Potentiometric CO2 Sensor for High-Resolution in Situ Measurements in Fresh Water Systems

Nadezda Pankratova, Bernhard Wehrli

We present a new potentiometric sensor principle and a calibration protocol for in situ profiling of dissolved CO2 with high temporal and spatial resolution in fresh water lakes. The sensor system is based on the measurement of EMF between two solid-contac ...

The Demographic and Adaptive History of the African Green Monkey

Susanne Petra Pfeifer

Relatively little is known about the evolutionary history of the African green monkey (genus Chlorocebus) due to the lack of sampled polymorphism data fromwild populations. Yet, this characterization of genetic diversity is not only critical for a better u ...

Mitochondrial DNA Analyses Indicate High Diversity, Expansive Population Growth and High Genetic Connectivity of Vent Copepods (Dirivultidae) across Different Oceans

Stefan Jean Laurent

Communities in spatially fragmented deep-sea hydrothermal vents rich in polymetallic sulfides could soon face major disturbance events due to deep-sea mineral mining, such that unraveling patterns of gene flow between hydrothermal vent populations will be ...
