Comparison of classical chromatographic tests with a chromatographic test applied to stationary phases prepared by thermal immobilization of poly(methyloctylsiloxane) onto silica.

Analytical and bioanalytical chemistry

Borges EM, Euerby MR, Collins CH.
PMID: 22307179
Anal Bioanal Chem. 2012 Dec;404(10):2985-3002. doi: 10.1007/s00216-012-5752-x. Epub 2012 Feb 04.

Stationary-phase evaluation in reversed-phase liquid chromatography (RP-LC) is not a straightforward process. A number of tests to characterize and classify stationary phases have been suggested. The results of these various tests, however, do not always describe the real properties...

Strong Reduction of Thermal Conductivity and Enhanced Thermoelectric Properties in CoSbS.

Scientific reports

Chmielowski R, Bhattacharya S, Jacob S, Péré D, Jacob A, Moriya K, Delatouche B, Roussel P, Madsen G, Dennler G.
PMID: 28425457
Sci Rep. 2017 Apr 20;7:46630. doi: 10.1038/srep46630.

In order to reduce the thermal conductivity of CoSbS, a newly developed thermoelectric semiconductor, we have aimed at intentionally induce atomic disorder in its structure. This endeavor was guided by Density Functional Theory(DFT) calculations which indicated that substituting sulfur...

Annual sulfur cycle in a warm monomictic lake with sub-millimolar sulfate concentrations.

Geochem Trans. 2015 Jul 02;16:7. doi: 10.1186/s12932-015-0021-5. eCollection 2015.

BACKGROUND: We studied the annual variability of the concentration and isotopic composition of main sulfur species and sulfide oxidation intermediates in the water column of monomictic fresh-water Lake Kinneret. Sulfate concentrations in the lake are

How to select equivalent and complimentary reversed phase liquid chromatography columns from column characterization databases.

Analytica chimica acta

PMID: 24356231
Anal Chim Acta. 2014 Jan 07;807:143-52. doi: 10.1016/j.aca.2013.11.010. Epub 2013 Nov 15.

Three RP-LC column characterization protocols [Tanaka et al. (1989), Snyder et al. (PQRI, 2002), and NIST SRM 870 (2000)] were evaluated using both Euclidian distance and Principal Components Analysis to evaluate effectiveness at identifying equivalent columns. These databases utilize...

Decomposition of abnormal free locomotor behavior in a rat model of Parkinson's disease.

Frontiers in systems neuroscience

Grieb B, von Nicolai C, Engler G, Sharott A, Papageorgiou I, Hamel W, Engel AK, Moll CK.

Front Syst Neurosci. 2013 Nov 27;7:95. doi: 10.3389/fnsys.2013.00095. eCollection 2013.

Poverty of spontaneous movement, slowed execution and reduced amplitudes of movement (akinesia, brady- and hypokinesia) are cardinal motor manifestations of Parkinson's disease that can be modeled in experimental animals by brain lesions affecting midbrain dopaminergic neurons. Most behavioral investigations...

Intrinsic coupling modes reveal the functional architecture of cortico-tectal networks.

Science advances

Stitt I, Galindo-Leon E, Pieper F, Engler G, Fiedler E, Stieglitz T, Engel AK.
PMID: 26601226
Sci Adv. 2015 Aug 07;1(7):e1500229. doi: 10.1126/sciadv.1500229. eCollection 2015 Aug.

In the absence of sensory stimulation or motor output, the brain exhibits complex spatiotemporal patterns of intrinsically generated neural activity. Analysis of ongoing brain dynamics has identified the prevailing modes of cortico-cortical interaction; however, little is known about how...

Vitellogenin (Vg), a yolk protein precursor, is the primary egg nutrient source involved in insect reproduction and embryo development. The Cotton Boll weevil (CBW) Anthonomus grandis Boheman, the most important cotton pest in Americas, accumulates large amounts of Vg...

Surface second harmonic generation from silicon pillar arrays with strong geometrical dependence.

We present experimental demonstration and analysis of enhanced surface second harmonic generation (SHG) from hexagonal arrays of silicon pillars. Three sets of Si pillar samples with truncated cone-shaped pillar arrays having periods of 500, 1000, and 2000 nm, and...

Reaction of five-membered zirconacycloallenoids with the strong Lewis acid B(C6F5)3.

Dalton transactions (Cambridge, England : 2003)

Bender G, Daniliuc CG, Wibbeling B, Kehr G, Erker G.
PMID: 25010740
Dalton Trans. 2014 Aug 28;43(32):12210-3. doi: 10.1039/c4dt01137f.

Two alkyl and aryl substituted five-membered zirconacycloallenoids underwent a typical σ-alkyl metallocene reaction with B(C6F5)3, namely cleavage of the Zr-C(sp(3)) bond with formation of zwitterionic (η(2)-allenyl)zirconium/alkylborate products. Both products were characterized by X-ray crystal structural analyses.
