Biogenetic space-guided synthesis of rearranged terpenoids

Alekseychuk, Mykhaylo; Heretsch, Philipp (Cambridge : Soc., 2023)

Natural product chemistry is constantly challenged by newly discovered, complex molecules. Elements of complexity arise from unprecedented frameworks, with a large amount of densely packed stereogenic centres and different ...
Comparison of the photoelectrochemical oxidation of methanol on rutile TiO 2 (001) and (100) single crystal faces studied by intensity modulated photocurrent spectroscopy

Ahmed, Amira Y.; Oekermann, Torsten; Lindner, Patrick; Bahnemann, Detlef W. (Cambridge : Royal Society of Chemistry, 2012)

The photooxidation of methanol as a model substance for pollutants on rutile TiO 2 (001) and (100) surfaces was investigated using intensity modulated photocurrent spectroscopy (IMPS). The results are analyzed in view of ...
Downstream processing of high chain length polysialic acid using membrane adsorbers and clay minerals for application in tissue engineering

Bice, Ismet; Celik, Hilal; Wolff, Christopher; Beutel, Sascha; Zahid, Maria; Hitzmann, Bernd; Rinas, Ursula; Kasper, Cornelia; Gerardy-Schahn, Rita; Scheper, Thomas (Weinheim : Wiley-VCH Verlag, 2013)

Polysialic acid (polySia) is a carbohydrate polymer of varying chain length. It is a promising scaffold material for tissue engineering. In this work, high chain length polySia was produced by an Escherichia coli K1 strain ...
Dryopteris juxtapostia Root and Shoot: Determination of Phytochemicals; Antioxidant, Anti-Inflammatory, and Hepatoprotective Effects; and Toxicity Assessment

Rani, Abida; Uzair, Muhammad; Ali, Shehbaz; Qamar, Muhammad; Ahmad, Naveed; Abbas, Malik Waseem; Esatbeyoglu, Tuba (Basel : MDPI, 2022)

An estimated 450 species of Dryopteris in the Dryoperidaceae family grow in Japan, North and South Korea, China, Pakistan, and Kashmir. This genus has been reported to have biological capabilities; however, research has ...
Enzymes: The two roles of complex iii in plants

Braun, Hans-Peter (Cambridge : eLife Sciences Publications, 2021)

Atomic structures of mitochondrial enzyme complexes in plants are shedding light on their multiple functions.
Exchange interaction in chirally coupled quantum dots

Tutuc, Daniel; Heine, Alexander W.; Schuh, Dieter; Wegscheider, Werner; Haug, Rolf J. (Bristol : IOP Publishing Ltd., 2013)

We present transport measurements on a system of two lateral quantum dots in a perpendicular magnetic field. Due to edge channel formation in an open conducting region, the quantum dots are chirally coupled. When both ...
High spatial resolution analysis of the iron oxidation state in silicate glasses using the electron probe

Hughes, Ery C.; Buse, Ben; Kearns, Stuart L.; Blundy, Jon D.; Kilgour, Geoff; Mader, Heidy M.; Brooker, Richard A.; Balzer, Robert; Botcharnikov, Roman E.; Di Genova, Danilo; Almeev, Renat R.; Riker, Jenny M. (McLean, VA : GeoScienceWorld, 2018)

The iron oxidation state in silicate melts is important for understanding their physical properties, although it is most often used to estimate the oxygen fugacity of magmatic systems. Often high spatial resolution analyses ...
Immiscible hydrous Fe-Ca-P melt and the origin of iron oxide-apatite ore deposits

Hou, Tong; Charlier, Bernard; Holtz, Francois; Veksler, Ilya; Zhang, Zhaochong; Thomas, Rainer; Namur, Olivier (London : Springer Nature, 2018)

The origin of iron oxide-apatite deposits is controversial. Silicate liquid immiscibility and separation of an iron-rich melt has been invoked, but Fe-Ca-P-rich and Si-poor melts similar in composition to the ore have never ...
In-Situ Characterization of Microstructural Changes in Alloy 718 during High-Temperature Low-Cycle Fatigue

Barton, Sebastian; Weiss, Maximilian K.-B.; Maier, Hans Juergen (Basel : MDPI, 2022)

Components made of nickel-based alloys are typically used for high-temperature applications because of their high corrosion resistance and very good creep and fatigue strength, even at temperatures around 1000 °C. Corrosive ...
Interkingdom interaction: the soil isopod Porcellio scaber stimulates the methane-driven bacterial and fungal interaction

Heffner, Tanja; Brami, Semi A.; Mendes, Lucas W.; Kaupper, Thomas; Hannula, Emilia S.; Poehlein, Anja; Horn, Marcus A.; Ho, Adrian ([London] : Springer Nature, 2023)

Porcellio scaber (woodlice) are (sub-)surface-dwelling isopods, widely recognized as “soil bioengineers”, modifying the edaphic properties of their habitat, and affecting carbon and nitrogen mineralization that leads to ...
Lipoxygenase-catalysed co-oxidation for sustained production of oxyfunctionalized terpenoids

Nikolaiczyk, Vanessa; Kirschning, Andreas; Díaz, Edison (New York, NY [u.a.] : Wiley, 2022)

Lipoxygenases (LOX) catalyse allylic oxidations and epoxidations of a co-substrate in the presence of an unsaturated fatty acid containing a 1,4-pentadiene moiety. One- and two-step enzyme assays were established to verify ...
The nature of chlorine-inhibition of photocatalytic degradation of dichloroacetic acid in a TiO2-based microreactor

Krivec, M.; Dillert, Ralf; Bahnemann, Detlef W.; Mehle, A.; Strancar, J.; Drazic, G. (Cambridge : Royal Society of Chemistry, 2014)

Photocatalytic degradation of dichloroacetic acid (DCA) was studied in a continuous-flow set-up using a titanium microreactor with an immobilized double-layered TiO2 nanoparticle/nanotube film. Chloride ions, formed during ...
New cyclopentadienylethylphosphane chelate complexes with unsymmetrical phosphane substitution

Janssen, Karin; Butenschön, Holger (Cambridge : Royal Society of Chemistry, 2011)

The syntheses, characterization, and some reactions of (phosphanylethyl) cyclopentadienyl chelate complexes of cobalt, rhodium, iridium, nickel, and chromium with unsymmetrical substitution at the phosphorus atom are ...
Oxidising agents in sub-arc mantle melts link slab devolatilisation and arc magmas

Bénard, Antoine; Klimm, Kevin; Woodland, Alan B.; Arculus, Richard J.; Wilke, Max; Botcharnikov, Roman E.; Shimizu, Nobumichi; Nebel, Oliver; Rivard, Camille; Ionov, Dmitri A. (London : Nature Publishing Group, 2018)

Subduction zone magmas are more oxidised on eruption than those at mid-ocean ridges. This is attributed either to oxidising components, derived from subducted lithosphere (slab) and added to the mantle wedge, or to oxidation ...
