Ceres: Sulfur deposits and graphitized carbon

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 ...

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...

Effect of Gas Diffusion in Graphitized Carbon Rods on Their Gasification Rate with Carbon Dioxide'>'

At high temperatures, the experimental gasification rates of graphitized carbon rods are found to deviate progressively more from their intrinsic gasification rates, aa temperature is increased. This is shown to be caused by the increasing control of the reaction by the rate of transport of carbon dioxide through the internal pores of the carbon rod. The ditTusionalresistance concepts used to c...

Atmospheric sulfur in Archean komatiite-hosted nickel deposits.

Some of Earth's largest iron-nickel (Fe-Ni) sulfide ore deposits formed during the Archean and early Proterozoic. Establishing the origin of the metals and sulfur in these deposits is critical for understanding their genesis. Here, we present multiple sulfur isotope data implying that the sulfur in Archean komatiite-hosted Fe-Ni sulfide deposits was previously processed through the atmosphere a...
