Cycloazulenylen

open access: yesAngewandte Chemie, EarlyView.
Ein ausschließlich aus Azulen‐Untereinheiten aufgebauter gespannter Makrocyclus mit der Bezeichnung [6]Cycloparaazulenylen ([6]CPA) wird vorgestellt. Der Makrocyclus weist für ein Azulensystem eine bemerkenswert kleine HOMO–LUMO‐Energielücke, eine durch die Ringspannung hervorgerufene bathochrome Verschiebung der Absorption sowie ein ungewöhnliches ...

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 ...

Minute‐Scale Repeated Metabolic Probing of Living Cells Enabled by Rapid Parahydrogen‐Based Hyperpolarization

open access: yesAngewandte Chemie International Edition, EarlyView.
Rapid parahydrogen hyperpolarization combined with simple dilution enables biocompatible delivery of hyperpolarized pyruvate to immobilized living cells within ≈1 min. Repeated substrate injections reveal frequency‐dependent metabolic dynamics, introducing a new temporal dimension for hyperpolarized NMR studies of cellular metabolism and enabling rapid

Scalable ω‐Substituted α‐Olefins via Living Chain Transfer Telomerization: A Platform for Next Generation Polyolefins

open access: yesAngewandte Chemie International Edition, EarlyView.
A highly versatile and general strategy is presented for the scalable production of practical quantities of ω‐substituted α‐olefins using tris(ω‐substituted alkyl)aluminum telogens that are readily available through a “green” synthesis from commodity triisobutylaluminum and ethene as the taxogen. These new α‐olefins can be designed and used as monomers

Granular Bed Filtration of Coal Pyrolysis Gas: Effects of Media Reactivity on Dust Removal and Products

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Granular bed filtration is a promising technology for removing dust from high‐temperature coal pyrolysis gas. In this work, the reactivity of coal pyrolysis products over ceramsite, char, ultrastable Y‐type (USY) zeolite, and quartz particles was compared.

Higher Complement C4 Gene Copy Number Constitutes a Shared Genetic Risk Factor for Giant Cell Arteritis and IgA Vasculitis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Low copy number (CN) of complement C4 isoforms and high CN of retroviral HERV‐K elements are known risk factors for many immune‐mediated inflammatory diseases (IMIDs), often showing sex‐biased effects. Here, we assessed whether CN variation within the C4 gene contributes to giant cell arteritis (GCA) and IgA vasculitis (IgAV), two complex ...

Charlotte Pommer: Resistance fighter and female pioneer of German anatomy

open access: yesAnatomical Sciences Education, EarlyView.
Abstract This article examines the biography and unique case of Charlotte Pommer (1914–2004), the only anatomist documented to have left the field during the Nazi period after encountering the regime's victims on the dissection table. While she is known for her resistance activities, newly presented documentation reveals her role as the provisional ...

Feasibility Study for Application of Digitized Henize Mt. Wilson Michigan Southern Sky Hα$$ \boldsymbol{\alpha} $$ Survey Low‐Dispersive Spectral Plates for Searches for Anomalous and Highly Redshifted Objects

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT The goal of this study is to confirm the feasibility of the use of digitized low dispersive MtWilson Michigan Southern Sky Hα$$ \alpha $$ survey astronomical photographic plates for modern astrophysical research. The detection of highly redshifted objects, such as early galaxies and quasars, is fundamental to understanding the universe's ...
