A novel multi-functional plate-like lamination that combines a thermal energy storage capability with a structural capability is described. The lamination consists of a paraffin impregnated porous graphitic core (the energy storage volume) encapsulated between rigid graphite/epoxy composite skins. Heat storage is via solid-liquid phase transition of the paraffin. Stacked laminations form a sand...

BACKGROUND/AIMS Detection of clonal immunoglobulin heavy chain (IgH) rearrangements by the polymerase chain reaction (PCR) is an attractive alternative to Southern blotting in lymphoma diagnostics. However, the advantages and limitations of PCR in clonality analysis are still not fully appreciated. In this study, clonality was analysed by means of PCR, focusing in particular on the sample size ...

abstract khuzestan province accommodates the largest oil-fields with huge petroleum production in iran. oil spills through transportations, oil pumping station and storage tanks are the cause of frequent contamination in land areas, including crop fields, imposing great damages to soil ecology. thus, oil removal from contaminated soil by advance technologies such as bioremediation seems to be o...

the potential indoor air impacts of burning candles have drawn increased attention in recent years.  burning paraffin waxes itself, regardless to wick and the essence, produce some allergens and even carcinogenic compounds. further biorefining of petroleum paraffin wax with proper bacteria is one of the proposed resolutions to decrease the health threat. therefore in this study iranian heavy cr...

Abstract The corrosion performance of phase change materials on stainless steel was studied using single fatty acid, acid/paraffin mixed and acid/paraffin/graphite composite as media. results show that the paraffin graphite to is very small; among them, stearic acid series are least corrosive can be used ideal energy storage medium for heat exchange devices.
