Multielectrocatalysis by layer-by-layer films based on pararosaniline and vanadium-substituted phosphomolybdate.

Langmuir : the ACS journal of surfaces and colloids

Fernandes DM, Teixeira A, Freire C.
PMID: 25603457
Langmuir. 2015 Feb 10;31(5):1855-65. doi: 10.1021/la5043266. Epub 2015 Jan 29.

Hybrid multilayer films based on the two molecular species pararosaniline (PR) and Keggin-type polyoxometalate K5[PMo11VO40)] (PMo11V) were prepared on different substrates using the electrostatic layer-by-layer (LbL) self-assembly method. The film buildup, monitored by electronic spectroscopy, showed a regular stepwise...

Biochemical and structural characterisation of the second oxidative crosslinking step during the biosynthesis of the glycopeptide antibiotic A47934.

Beilstein journal of organic chemistry

Ulrich V, Brieke C, Cryle MJ.
PMID: 28144358
Beilstein J Org Chem. 2016 Dec 27;12:2849-2864. doi: 10.3762/bjoc.12.284. eCollection 2016.

The chemical complexity and biological activity of the glycopeptide antibiotics (GPAs) stems from their unique crosslinked structure, which is generated by the actions of cytochrome P450 (Oxy) enzymes that affect the crosslinking of aromatic side chains of amino acid...

C-banding patterns were analysed in 19 different accessions of Aegilops caudata (= Ae. markgrafii, = Triticum dichasians) (2n = 14, genomically CC) from Turkey, Greece and the USSR, and a generalized C-banded karyotype was established. Chromosome specific C-bands are...

Functional characterization of a yellow laccase from Leucoagaricus gongylophorus.

Springerplus. 2015 Oct 30;4:654. doi: 10.1186/s40064-015-1464-y. eCollection 2015.

In this work we have identified, using mass spectrometry, two laccases produced by Leucoagaricus gongylophorus. One of them, Lac1Lg, was isolated, purified and characterized. Lac1Lg, a monomeric enzyme, was studied using ABTS and syringaldazine substrates. Lac1Lg presented kcat/Km almost...

Comparative Study of MIL-96(Al) as Continuous Metal-Organic Frameworks Layer and Mixed-Matrix Membrane.

ACS Appl Mater Interfaces. 2016 Mar 23;8(11):7536-44. doi: 10.1021/acsami.5b12541. Epub 2016 Mar 08.

MIL-96(Al) layers were prepared as supported metal-organic frameworks membrane via reactive seeding using the α-alumina support as the Al source for the formation of the MIL-96(Al) seeds. Depending on the solvent mixture employed during seed formation, two different crystal...

A combined electrochemical quartz-crystal microbalance probe beam deflection (EQCM-PBD) study of solvent and ion transfers at a poly.

Chemistry (Weinheim an der Bergstrasse, Germany)

Vilas-Boas M, Henderson MJ, Freire C, Hillman AR, Vieil E.
PMID: 10785801
Chemistry. 2000 Apr 03;6(7):1160-7. doi: 10.1002/(sici)1521-3765(20000403)6:7<1160::aid-chem1160>3.3.co;2-u.

The oxidative polymerisation of the complex2,3-dimethyl-N,N'-bis-(salicylidene)butane-2,3-diaminatonick-el(II), [Ni(saltMe)], was monitored by the electrochemical quartz microbalance (EQCM) and crystal impedance techniques. Polymerisation efficiency was maintained throughout deposition of a film, which behaved rigidly, on the electrode. A combined EQCM-PBD (probe beam...

Sesquiterpene constituents of the liverwort Calypogeia muelleriana.

Phytochemistry

Warmers U, Wihstutz K, Bülow N, Fricke C, König WA.
PMID: 11711089
Phytochemistry. 1998 Nov 20;49(6):1723-1731. doi: 10.1016/s0031-9422(98)00283-0.

The lipophilic constituents of the liverwort Calypogeia muelleriana were investigated. A new sesquiterpene hydrocarbon, maali-1,3-diene, and two sesquiterpene alcohols with an aromadendrane skeleton, 3-hydroxyledene and 4,5-dehydroviridiflorol, were isolated and identified. The structure elucidation was carried out mainly by NMR...

Older Motherhood and the Changing Life Course in the Era of Assisted Reproductive Technologies.

Journal of aging studies

Friese C, Becker G, Nachtigall RD.
PMID: 18443646
J Aging Stud. 2008 Jan;22(1):65-73. doi: 10.1016/j.jaging.2007.05.009.

Midlife, once a focus of particular interest to gerontologists because of its implications for later life, has recently received little attention. But as new reproductive technologies have expanded in the United States, motherhood is occurring at older ages. While...

Viscoelastic characterization of benzo-crown ether functionalized electroactive films.

Physical chemistry chemical physics : PCCP

Tedim J, Freire C, Hillman AR.
PMID: 19088982
Phys Chem Chem Phys. 2009 Jan 14;11(2):268-77. doi: 10.1039/b810562f. Epub 2008 Oct 20.

Electrochemical, acoustic wave and imaging (AFM) methods were used to characterize electroactive poly[Ni(3-Mesalophen-b15-c5)] films. The distinct physical principles of these techniques generate different responses to film characteristics, such that their simplistic correlation in the context of a single uniform...
