Recently, radiation-absorbing phase change material (PCM) for thermal storage that can discharge energy on demand when no radiation is present has been developed and tested indoors. Organic materials with limited conductivity slow down the response processes charging discharging. For various industrial applications, much research devoted to introduction of solar collectors best possible integra...

Mandarin hybrids were treated with wax and resin coatings having differing oxygen permeabilities. After storage for 7 days at 21 °C, fruit with coatings having O2 permeability 1.1×10 mol m s m Pa were rated by a sensory panel as markedly less fresh than fruit with higher permeability coatings. These low-permeability coatings were those composed mainly of shellac and wood resin. The flavor chang...

Several quality attributes of wax apple cider vinegar (WACV) were determined every 30 days for six months at ambient temperature. Acetic acid fermentation significantly increased the acetic content in WACV. The light-ness and yellowness gradually decreased, whereas redness during storage. Density, viscosity, pH WACV continuously retarded, total acidity, volatile electrical conductivity, nitroge...

Energy status was analyzed in glass eels captured during two early waves of arrival at the mouths of the Mersey River, Nova Scotia, Canada (MR), and Grande-Rivière-Blanche, Québec, Canada (GRB), and according to their salinity preference (freshwater, brackish, or saltwater). Glass eels captured in the GRB estuary were larger, more pigmented, and exhibited higher whole-body glycogen, phospholipi...

The objective of this study was to evaluate the internal quality and lipid oxidation eggs coated with a carnauba wax-based product at different concentrations stored for up 28 days under two temperatures. For analysis quality, were assigned completely randomized 3 x 4 factorial design (uncoated (control); wax 12% concentration (Aruá®); 15% four storage periods - 7, 14, 21, days). Fifteen from e...

To extend the shelf life of Aonla fruits and to regulate marketing for acceptability profit during distant transportation storage, can be coated with chemicals coating materials which are safe consumption packed in packaging materials. So, find out effect different on quality (Emblica officinalis L.); a lab experiment was conducted at Post Harvest Laboratory, Department Horticulture, Naini Agri...

Deposition of wax on a cold surface is a serious problem in oil production. Progress in developing more effective wax inhibitors has been impeded by the lack of an established mechanism connecting the molecular structure to inhibitor efficiency. Some comb-like polymers having long alkyl side chains are known to decrease the rate of wax formation. Among several possible mechanisms, we investigat...

A significant amount of heat is wasted in manufacturing process, electricity generation, chemical and industrial process. Recovery and reuse of this energy through storage can be useful in conservation of energy. In the present study, a double pipe type heat exchanger has been designed and fabricated for low temperature industrial waste heat recovery using phase change material (PCM) paraffin w...

Microencapsulated paraffin wax/polyaniline was prepared using a simple in situ polymerization technique, and its performance characteristics were investigated. Weight losses of samples were determined by Thermal Gravimetry Analysis (TGA). The microencapsulated samples with 23% and 49% paraffin showed less decomposition after 330 °C than with higher percentage of paraffin. These samples were the...
