Xu T, Schwarz M, Werner K, Mohr S, Amende M, Libuda J.
PMID: 27030374
Phys Chem Chem Phys. 2016 Apr 21;18(15):10419-27. doi: 10.1039/c6cp00296j. Epub 2016 Mar 31.

We have investigated the influence of the structure of oxide surfaces on the thermal stability of anchored phthalic acid (PA) thin films. Specifically, we have performed temperature programmed infrared reflection absorption spectroscopy (TP-IRAS) of PA films deposited by physical...

Schistosoma haematobium affects more than 100 million people throughout Africa and is the causative agent of urogenital schistosomiasis. The parasite is strongly associated with urothelial cancer in infected individuals and as such is designated a group I carcinogen by...

Bloch Waves in Minimal Landau Gauge and the Infinite-Volume Limit of Lattice Gauge Theory.

Cucchieri A, Mendes T.
PMID: 28548507
Phys Rev Lett. 2017 May 12;118(19):192002. doi: 10.1103/PhysRevLett.118.192002. Epub 2017 May 09.

By exploiting the similarity between Bloch's theorem for electrons in crystalline solids and the problem of Landau gauge fixing in Yang-Mills theory on a "replicated" lattice, we show that large-volume results can be reproduced by simulations performed on much...

Coenzyme Q regulates the expression of essential genes of the pathogen- and xenobiotic-associated defense pathway in C. elegans.

Journal of clinical biochemistry and nutrition

Fischer A, Niklowitz P, Menke T, Döring F.
PMID: 26566301
J Clin Biochem Nutr. 2015 Nov;57(3):171-7. doi: 10.3164/jcbn.15-46. Epub 2015 Aug 29.

Coenzyme Q (CoQ) is necessary for mitochondrial energy production and modulates the expression of genes that are important for inflammatory processes, growth and detoxification reactions. A cellular surveillance-activated detoxification and defenses (cSADDs) pathway has been recently identified in C....

Photosynth Res. 1996 Sep;49(3):277-80. doi: 10.1007/BF00034789.

The light-induced oxidation of the accessory donor tyrosine-D (YD) has been studied by measurements of the EPR Signal IIslow at room temperature in the autotrophically and photoheterotrophically cultivated alga Chlamydobotrys stellata. After illumination and dark adaptation, YD Signal IIslow...

Functionalized Porphyrins on an Atomically Defined Oxide Surface: Anchoring and Coverage-Dependent Reorientation of MCTPP on Co3O4(111).

The journal of physical chemistry letters

Werner K, Mohr S, Schwarz M, Xu T, Amende M, Döpper T, Görling A, Libuda J.
PMID: 26785148
J Phys Chem Lett. 2016 Feb 04;7(3):555-60. doi: 10.1021/acs.jpclett.5b02784. Epub 2016 Jan 25.

We have studied the adsorption of tetraphenylporphyrin (2HTPP) and its carboxylated counterpart mono-para-carboxyphenyltriphenylporphyrin (MCTPP) on an atomically defined Co3O4(111) film under ultrahigh vacuum (UHV) conditions. Using time-resolved infrared reflection absorption spectroscopy (TR-IRAS), we show that 2HTPP adsorbs molecularly in...

Phthalide-based host-plant resistance toSpodoptera exigua andTrichoplusia ni inApium graveolens.

Journal of chemical ecology

Meade T, Daniel Hare J, Midland SL, Millar JG, Sims JJ.
PMID: 24242122
J Chem Ecol. 1994 Mar;20(3):709-26. doi: 10.1007/BF02059608.

A chemical basis for the difference in suitability between two celeriac (Apium graveolens var.rapaceum) cultivars for the survival and growth ofSpodoptera exigua (Hübner) andTrichoplusia ni (Hübner) was identified as sedanenolide (3-n-butyl-4,5-dihydro-isobenzofuranone). Sedanenolide was isolated using a bioassay-driven extraction and...

Interaction between a Solute Molecule and a Fluorocarbon Bonded Layer in Reversed-Phase High-Performance Liquid Chromatography.

Glassesand silica-gel packings modified with fluorocarbon and hydrocarbon silylation agents were prepared to investigate the separation mechanism of a fluorocarbon bonded layer in reversed-phase high-performance liquid chromatography (RP-HPLC). On the hydrocarbon layer the contact angles of benzene (Be) and...

Entanglement between an electron and a nuclear spin 1/2.
