Metabolische Untersuchungen lebender Zellen im Minutentakt, ermöglicht durch schnelle Parawasserstoff‐basierte Hyperpolarisation

open access: yesAngewandte Chemie, EarlyView.
Die schnelle Parawasserstoff‐Hyperpolarisation in Kombination mit einfacher Verdünnung ermöglicht die Zufuhr von hyperpolarisiertem, biokompatiblen Pyruvats zu immobilisierten lebenden Zellen innerhalb von ≈1 min. Wiederholte Substratinjektionen offenbaren frequenzabhängige metabolische Dynamiken und eröffnen damit eine neue zeitliche Dimension für ...

Eine Interphase mit ortsfesten Ladungen synchronisiert den Ionentransport und unterdrückt raumladungsgetriebene Ineffizienz unter räumlicher Begrenzung auf Nanoliter‐Volumina

open access: yesAngewandte Chemie, EarlyView.
Die elektrochemische Energiespeicherung stößt bei extremer Miniaturisierung an fundamentale Grenzen, da Grenzflächen‐ und Raumladungseffekte dominieren. Hier stellen wir eine selektive Interphase mit ortsfesten Ladungen in einer Zwillingsrohr‐μ‐Swiss‐Roll‐Architektur vor.

Transportation and the Environment [PDF]

open access: yesAnnual Review of Environment and Resources, 2011
The growth of CO2-intensive transport, mobility and the impact of transport on the environment are reviewed. The recent global exponential growth in transport is unsustainable and must end unless the transport sector can decarbonize. The paper examines solutions for low-carbon transport systems; the behavioral options; possible demand reduction; the ...

Kooperative Redox‐Katalyse der N2O‐Zersetzung mittels auf Co3O4 geträgerten RhOx‐ und CeOx‐Spezies mit kurzreichweitiger Wechselwirkung

open access: yesAngewandte Chemie, EarlyView.
A short‐range Rh‐O‐Co‐O‐Ce interfacial moiety drives low‐temperature N2O decomposition via a cooperative redox cycle. Operando modulated‐excitation XAS with phase‐sensitive detection (ME‐XAS+PSD) tracks rapid, reversible Rh oxidation coupled to Co reduction. Combined kinetics and DFT rationalize the activity trends and identify the Rh‐O‐Co interface as

Two‐phase ammonia plume behavior in a still room: Jack Rabbit III chamber studies

open access: yesProcess Safety Progress, EarlyView.
Abstract This paper describes a new set of 45 laboratory experiments where about 180 g of ammonia was released from pressurized liquefied storage in a still 51.3 m3 chamber (i.e., a small room) and the variations of the ammonia gas concentrations and liquid deposition over a 60 min time period were investigated.

Quality indicators in interhospital transport: Multicentre project

open access: yesAnales de Pediatría (English Edition), 2021
Introduction: Interhospital transport is carried out by variable teams in different regions of our country, and this makes quality evaluation and benchmarking complicated. Project objective: Select and define a consensual list of quality measurement that

To Transport or Not to Transport: Post‐Growth Avenues for Transport Infrastructure Planning

open access: yesJournal of Critical Infrastructure Policy
AbstractPost‐growth literature has recently raised attention to the role of transport infrastructure planning in relation to global sustainability challenges and human wellbeing. Transport infrastructure can be a major obstacle to change, due to sunk costs, material intensity, and historical path dependencies.

Potencialidad reactiva de agregados para hormigón en Uruguay. Correlación entre la metodología de la barra de mortero y el prisma de hormigón (acelerada y tradicional)

open access: yesRevista ALCONPAT, 2022
Se analizó la correlación entre los criterios internacionales para definir el grado de reactividad en los ensayos de expansión de la barra de mortero y del prisma de hormigón (metodología acelerada y tradicional). Experimentalmente se aplicaron las tres

Cache‐Cache: Dans les souffles du Grand Fleuve…

open access: yesAnthropology of Consciousness, EarlyView.
ABSTRACT Between ventriloquism and divination, devotion and consecration, an old and sublime marine game unfolds each day, with living breaths shared in the waters of the great river. In Tadoussac, on the north shore of the St. Lawrence Estuary, at the mouth of the Saguenay, the rumor of whales has long resonated.
