The equivalent chain length (ECL) has been widely accepted as an identification tool for fatty acid methyl esters (FAMEs). In this study, FAMEs from the seed oil of Chinese mustard (Brassica juncea) analyzed on a 0.25-mm-i.d. capillary column coated with an SA-WAX are used as an example for the calculation of the ECL in single-, two-, three-, and four-step temperature-programmed gas chromatogra...

most reservoir fluids contain heavy paraffinic compounds that may precipitate as a solid or solid like material called wax if the fluid is cooled down. wax precipitation is a phenomenon of considerable importance in oil industry. an increase in aggregation results in enhanced oil viscosity. this however causes significant negative effects on production, transportation and processing of crude oi...

In this study, natural linseed oil, hard wax and wax, commonly used as finishes for wooden furniture parquet, were surface on Turkey oak wood (Quercus cerris L.), thermally modified at temperatures of 175 °C 195 4 h. Several resistance properties investigated. The mechanical all very much allied to interactions between the finish type substrate. adhesion strength impact decreased if higher temp...

BACKGROUND Wax esters are industrially relevant molecules exploited in several applications of oleochemistry and food industry. At the moment, the production processes mostly rely on chemical synthesis from rather expensive starting materials, and therefore solutions are sought from biotechnology. Bacterial wax esters are attractive alternatives, and especially the wax ester metabolism of Acine...

The impeding effect of plant surfaces covered with three-dimensional wax on attachment and locomotion of insects has been shown previously in numerous experimental studies. The aim of this study was to examine the effect of different parameters of crystalline wax coverage on insect attachment. We performed traction experiments with the beetle Coccinella septempunctata and pull-off force measure...
