Method for preparing an at least partially acetal-protected sugar
Jeremy Luterbacher, Songlan Sun, Lorenz Perry Manker, Anastasiia Komarova
The present invention relates to a method for preparing an at least partially acetal-protected sugar involving the step of reacting a sugar or a sugar derivative selected from the group consisting of an aldopentose, an aldohexose, an aldopentoside and an a ...
2024Mechanistic studies of DNP and applications of hyperpolarized probes to study renal physiology and metabolism
Dissolution dynamic nuclear polarization (dDNP) is a powerful technique that enhances the magnetic resonance signal of nuclear spins by several orders of magnitude. DNP relies on the principle of cross-relaxation by electron spins driven out of equilibrium ...
EPFL2021Dissolution-reprecipitation reaction of dolomite: investigation of self- and tracer-diffusion using SIMS mini-spot and NanoSIMS profiles
Anders Meibom, Stéphane Laurent Escrig, Lukas Baumgartner
Recrystallization of minerals due to fluid infiltration modifies their original chemical and isotopic signature. Such processes are sought after as they give access to timescales of geologic processes, which are commonly quantified using diffusion chronome ...
2019Spatial and temporal changes of primary production in a deep peri-alpine lake
Alfred Johny Wüest, Damien Bouffard, Tiit Kutser
Lake productivity is fundamental to biogeochemical budgets as well as estimating ecological state and predicting future development. Combining modelling with Earth Observation data facilitates a new perspective for studying lake primary production. In this ...
2019Probing renal pH using hyperpolarized [1-13C]alaninamide
Rolf Gruetter, Arnaud Comment, Hikari Ananda Infinity Yoshihara, Alice Radaelli
Hyperpolarized molecular probes can be effectively used as pH markers. To date, the only two probes reported in vivo as extracellular pH sensors are 13C-bicarbonate, and [1,5-13C2]zymonic acid. Alaninamide is a derivative of alanine which is found to be se ...
2018Monitoring Membrane Lipidome Turnover by Metabolic N-15 Labeling and Shotgun Ultra-High-Resolution Orbitrap Fourier Transform Mass Spectrometry
Yury Tsybin, Konstantin Nagornov, Kristina Srzentic
Lipidomes undergo permanent extensive remodeling, but how the turnover rate differs between lipid classes and molecular species is poorly understood. We employed metabolic N-15 labeling and shotgun ultra-high-resolution mass spectrometry (sUHR) to quantify ...
Amer Chemical Soc2017Exploring biochemical pathways for mono-ethylene glycol (MEG) synthesis from synthesis gas
Vassily Hatzimanikatis, Meriç Ataman, Noushin Hadadi
Mono-ethylene glycol (MEG) is an important petrochemical with widespread use in numerous consumer products. The current industrial MEG-production process relies on non-renewable fossil fuel-based feedstocks, such as petroleum, natural gas, and naphtha; hen ...
Academic Press Inc Elsevier Science2017Technical note: Relating functional group measurements to carbon types for improved model-measurement comparisons of organic aerosol composition
Satoshi Takahama, Giulia Ruggeri
Functional group (FG) analysis provides a means by which functionalization in organic aerosol can be attributed to the abundances of its underlying molecular structures. However, performing this attribution requires additional, unobserved details about the ...
Copernicus GmbH2017Photosymbiosis and the expansion of shallow-water corals
Anders Meibom, Jaroslaw Hubert Stolarski
Roughly 240 million years ago (Ma), scleractinian corals rapidly expanded and diversified across shallow marine environments. The main driver behind this evolution is uncertain, but the ecological success of modern reefbuilding corals is attributed to thei ...
Amer Assoc Advancement Science2016Feeding behaviour of a benthic species (Ammonia tepida) under oxic and anoxic conditions: TEM-NanoSIMS correlation
Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin
More and more marine areas are subjected to depleted-O2 concentration, mainly due to eutrophication induced by human activities. These phenomena affect benthic ecosystems, in particular continental shelves and coastal areas where the renewal of the bottom ...
