Performance of low temperature fuel cells depends critically on the nanostructures of the material components in the electrodes and membranes. Some studies are reported here for 1) mixed metal nanoparticles supported on mesoporous carbon and 2) modification of nanopores of Nafion via in-situ polymerization of furfuryl alcohol. The anodic oxidation of small organic molecules such as alcohols in ...

BACKGROUND Children with Down syndrome (DS) have increased risk for developing AML (DS-AMKL), and they usually experience severe therapy-related toxicities compared to non DS-AMKL. Refractory/relapsed disease has very poor outcome, and patients would benefit from novel, less toxic, therapeutic strategies that overcome resistance. Relapse/resistance are linked to cancer stem cells with high alde...

ordered mesoporous carbon cmk-3 (omc) have been synthesized using mesoporous sba-15 silica as template and modified with cobalt carbonate. morphologies and surface texturing of materials werecharacterized by x-ray diffraction (xrd), scanning electron microscopy (sem) and n2 adsorption-desorptionisotherms. the cobalt modified ordered mesoporous carbon were found to have a surface area of 490.06m...

Two twin series of carbon replicas were synthesized by the acid-catalyzed precipitation polycondensation various amounts furfuryl alcohol in SBA-15 suspensions using water and toluene as reaction media. The textural structural parameters, well morphology polymer/silica carbonizates corresponding replicas, investigated comprehensively. It was found that polarity medium plays an essential role sc...

The hydrolysis of cellulose over sulfonated carbons was promoted greatly by elevating the sulfonation temperature. With 250 degrees C-sulfonated CMK-3 as a catalyst, the cellulose was selectively hydrolyzed into glucose with the glucose yield as high as 74.5%, which is the highest level reported so far on solid acid catalysts.

A crucial step in the arenavirus life cycle is the biosynthesis of the viral envelope glycoprotein (GP) responsible for virus attachment and entry. Processing of the GP precursor (GPC) by the cellular proprotein convertase site 1 protease (S1P), also known as subtilisin-kexin-isozyme 1 (SKI-1), is crucial for cell-to-cell propagation of infection and production of infectious virus. Here, we sou...
