Oligosaccharide analysis by graphitized carbon liquid chromatography–mass spectrometry

Clinical Glycomics Employing Graphitized Carbon Liquid Chromatography–Mass Spectrometry

Glycoconjugates and free glycan are involved in a variety of biological processes such as cell-cell interaction and cell trafficking. Alterations in the complex glycosylation machinery have been correlated with various pathological processes including cancer progression and metastasis. Mass Spectrometry (MS) has evolved as one of the most powerful tools in glycomics and glycoproteomics and in c...

Characterization of Polymer Carbon Sieves, Graphitized Polymer Carbons and Graphitized Carbon Blacks for Sample Preparation Applications

Self-assembled chains of graphitized carbon nanoparticles

We report a technique which allows self-assembly of conducting nanoparticles into long continuous chains. Transport properties of such chains have been studied at low temperatures. At low bias voltages, the charges are pinned and the chain resistance is exponentially high. Above a certain threshold VT , the system enters a conducting state. The threshold voltage is much bigger than the Coulomb ...

Organic compounds present in the natural Amazonian aerosol: Characterization by gas chromatographymass spectrometry

[1] As part of the Large-Scale Biosphere-Atmosphere Experiment in Amazonia (LBA)Cooperative LBA Airborne Regional Experiment (CLAIRE) 2001 campaign in July 2001, separate day and nighttime aerosol samples were collected at a ground-based site in Amazonia, Brazil, in order to examine the composition and temporal variability of the natural ‘‘background’’ aerosol. We used a high-volume sampler to ...
