This experiment was repeated for different nucleation temperatures and fit well with the theoretical predictions. An increase of 90% in the solidification duration was observed when the supercooling degree dropped from 35 to 8 K. Thanks to an original experimental bench, this temperature record has ...
For laboratory use, sodium acetate is very inexpensive, and is usually purchased instead of being synthesized. It is sometimes produced in a laboratory experiment by the reaction of acetic acid (ethanoic acid) with sodium carbonate, sodium bicarbonate, or sodium hydroxide. These reactions produce aqu...

1. Wear protective glasses, protective clothing and masks, gloves, and avoid contact with the skin during the experiment. 2. The waste generated after the experiment needs to be stored separately, and handed over to a professional biological waste gas treatment company to avoid environmental polluti...
Basically, semi-crystalline polymers have smaller processing ranges than amorphous polymers due to specific windows of melting and crystallization. Biopolymers are typically sensitive to thermo-mechanical stress during processing. They often exhibit a small processing range and significant loss of their ...
The log BCFs of triphenyltin in crucian carp obtained in a 7-day experiment were 1.70 (muscle), 1.70 (vertebra); 2.05 (liver); and 1.49 (kidney)(3). In studies in which the bioaccumulation and elimination of triphentyltin in Red Sea bream (Pagrus major) was by direct uptake from ...
For each experiment, normal distribution was tested by D'Agostino & Pearson omnibus test or evaluation of the residuals (when experimental sample numbers were o8). When comparing two groups, differences for paired samples were compared using the paired Student's t-test, and unpaired samples were...
