Wax Anti-Settling Additives
Wax anti-settling additives (WASA) are used to mitigate against the problems caused by the settling of n-alkane wax crystals, which crystallise from petroleum diesel. This can result in the blocking of fuel filters and hence vehicle failure. However, the mode of action for such additives is not …

Montan wax from California lignites
<p>Montan wax has been extracted from the lignite deposits of Germany since the early part of the twentieth century, The wax was named by von Boyen (1901), The word Montan is derived from the Latin term montanus meaning "of a mountain," The wax has found extensive uses in polishes, insulating …

Estimation of Wax Deposition in Subsea Pipelines
… multi-physics low dimensional model forecasting wax deposition rate within subsea production pipelines. This research employs experiments from 1-D and 2-D multiphase flow that have been successfully matched by a combined physics model on a closed-loop structure where the measuring length was 2.5m …

Wax distribution quantification using digital image analysis techniques
A wax distribution quantification procedure using digital image analysis and fluorescence microscopy techniques was developed. The procedure was evaluated by investigating the effect that variable application rates have on wax distribution. The effect of emulsion type and application on |B …

Characterization of xtcl mutant with reduced cuticular wax accumulation
Cuticular wax is a component of the plant cuticle, the lipid barrier which covers the surface of above ground primary plant organs and plays important protective roles. The isolation of wax deficient mutants from Arabidopsis and other plants resulted in identification and isolation of genes …

The urea adducts of the constituents of California montan wax
… in the chemical constitution of montan wax began with the work of Von Boyen, who in 1901 showed montanic acid to be a constituent of the wax. In the years that followed the literature has been rich with respect to investigations of montan wax. Most of the literature concerns itself with …

Assessing Hydrologic Connectivity using Water Temperature, Wax Lake Delta, Louisiana
… channel and interdistributary island on the Wax Lake Delta of coastal Louisiana. We deployed a relatively inexpensive, open-source data logging platform to collect high quality continuous water temperature, water depth, air temperature, and shortwave solar radiation from a portion of Wax Lake …

Composition of cuticular wax on the leaves of kalanchoe daigremontiana
Analysis of cuticular wax from Kalanchoe daigremontiana leaves was performed to identify the constituent components within the wax, determine how these changed during leaf ontogenesis, and discover how they were distributed within the cuticle. Analysis of extracted cuticular wax by gas …

Novel Carbopol-Wax Blends for Controlled Release Oral Dosage Forms
… free-flowing, directly compressible carbopol-wax blends. Evaluation of granular characteristics of carbopol-wax blends indicated that changes in the granular characteristics is dependent on process variables such as granulation temperature, granulation time and mixing speed. At higher …

Low-cost selective deposition of wax onto textured solar cells
… regions of a solar cell must be inoculated with wax, while leaving the metal fingers and bus bars bare, in preparation for the electroplating step of a new solar panel manufacturing process. Different methods to achieve the inoculation of the cell are discussed, along with their advantages and …

Wax extraction and characterization from full-fat and defatted rice bran
Rice bran oil (RBO) contains 3-4% waxes (rice bran wax, RBW), which are composed of wax esters (WE), hydrocarbons, and other minor constituents. Saponified rice bran wax esters (RBWE) generate fatty acids, long chain alcohols, and phytosterols. Phytosterols and long chain fatty alcohols …

A structural and thermodynamic study of non-aqueous solvent/wax systems
Non-aqueous wax/solvent systems of industrial relevance for the manufacture of paste polishes have been investigated. These mixtures have been modelled using a paraffin wax of Japanese origin (Nippon Seiro 140/145°F) in a solution of pure heptane to which dopant components are added.The stability …
