Differentiation of Plant and Animal‐Derived Cholesterol Using irm‐13C NMR and IRMS

Magnetic Resonance in Chemistry, EarlyView.
Determining and certifying the origin of ingredients, starting materials, and excipients used in manufactured goods like cosmetics and medicines can be difficult. In this report, we describe a robust approach for identifying the origin of cholesterol, a component of myriad consumer products using irm‐13C NMR and IRMS to differentiate plant versus ...

Quantification of Homopolymer Impurities in Structured Acrylate Copolymers Produced by High‐Temperature Semi‐Batch Radical Polymerization

Macromolecular Reaction Engineering, EarlyView.
Isobornyl acrylate macromonomer solutions are synthesized via high‐temperature radical polymerization using a starved‐feed semi‐batch operating policy. Through sequential feeding, the macromonomer solution functions as an addition‐fragmentation agent, facilitating the production of blocky and comb acrylate copolymers.

On the Origin of the Brain Semi‐Heavy Water Deuterium MR Signal Following Administration of Deuterated Metabolic Substrate: A Cautionary Tale

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To evaluate the extent to which the appearance of HOD in the brain following systemic administration of a deuterated substrate is due to local brain metabolism versus body metabolism. Methods [6,6‐2H2]glucose, which is transported across the blood‐brain barrier (BBB), and [6,6‐2H2]fructose (Fruc), which does not cross the BBB, were ...

Matching habitat choice could be brightness‐based instead of hue‐based in green‐brown polymorphic grasshoppers

Oikos, EarlyView.
Some prey species have evolved background matching, that is they resemble their surrounding environment in terms of colour and/or brightness. When prey populations inhabit patchy environments, they may even have evolved specialised phenotypes: each phenotype matching a specific subset of patches.

Neue Einblicke in ein Schlüsselmaterial für Planetenphysik, Fusion und Materialforschung: Flüssiger Kohlenstoff

Physik in unserer Zeit, EarlyView.
Mit Hilfe der ultrahellen Röntgenpulse des European XFEL und einem speziellen Hochenergielaser konnte die Struktur von flüssigem Kohlenstoff bei Drücken von über einer Million Atmosphären und Temperaturen von etwa 7000 K bestimmt werden. Dieser Ansatz offenbarte eine komplexe Flüssigkeit mit einer wasserähnlichen Struktur und im Mittel vier ...
