Determination of heat capacity of carbon composites with application to carbon/phenolic ablators up to high temperatures...
In this work, nitrogen-doped carbon with hierarchical porous and hollow sphere structure has been synthesized through a simple and facile route of spray drying using glycine as the nitrogen-containing carbon source. After KOH activation, the prepared material (NHPCA) shows a large specific surface area of 962m(2)g(-1) with moderate N-doping of 5.74...
We synthesized ordered mesoporous Fe/N/C with highly active Fe-N-X/C sitesdenoted as m-FePhen-C as a non precious metal catalyst (NPMC) for the oxygen reduction reaction in fuel cells. This was the first study that incorporated a catalyst precursor with Fe-N coordination directly in a simple block co-polymer-assisted soft template method for the sy...

Tunable large pore soft templated mesoporous carbons (SMC) were obtained via the organic self-assembly of resorcinol/formaldehyde with the triblock copolymer F127 and by investigating the effect of carbon precursor to surfactant (p/s) ratio and carbonization temperature on the material characteristics. The p/s ratio and carbonization temperature we...
Polymer resins are used for ground reinforcement in coal mines. This is made necessary by the fracturing of the rock caused by the great depth of the mines, and the consequent problems of roof support. In France, following a number of incidents resulting from the use of polyurethane resins, these materials have been replaced by phenolic resins for ...
