The cloud point, which generally occurs at a higher temperature than the pour point, is the temperature at which a liquid fatty material becomes cloudy due to the formation of crystals and solidification of saturates. Moreover, a fuel suitable for low ambient temperature must have lowest cold ...

crystals of the aromatic polycarboxylic acid by the impeller is suppressed. For this purpose, an inverter may be disposed in the pump and the speed of rotation of the impeller may be controlled. Fracture of the crystals can be suppressed also by expanding the gap between the impeller and the...
New insights into the role of calcium dioleate in selectively separating fluorite from calcite during cleaning process 2022, Colloids and Surfaces A: Physicochemical and Engineering Aspects Citation Excerpt : Numerous calcium ions are in the slurry of fluorite and calcite, and they can react with olei...
(Supplementary Figure1), which is suitable for single crystal X-ray diffraction data collection under synchrotron radiation, easy recovery of the material during the filtration process to collect the MOF after the synthesis and/or activation/cleaning in solution as well. On the contrary, reactions ...
Cellulose tailored semiconductors for advanced photocatalysis 2022, Renewable and Sustainable Energy Reviews Show abstract Flexible bacterial cellulose-based BC-SiO<inf>2</inf>-TiO<inf>2</inf>-Ag membranes with self-cleaning, photocatalytic, antibacterial and UV-shielding properties as a potential multifu...
According to Figure 1a, the pH(s) can thus be increased, either by decreasing this quantity of acid compared to the neutralization conditions (i.e., [HNO3]in = 125 mmol·L−1 for sample 05MgSiH1K0), or by adding variable quantities of KOH while keeping [HNO3]in constant at 125 ...
(pH = 12) and 0.2 mg /mL of Lipase in phosphate−buffered solution. All the samples were kept at 37 °C, the buffer solutions were replaced and the samples were taken every 7 days. After cleaning, the samples were dried at 60 °C for 24 h. The degradation behavior was evaluated ...
whereas intensities of the quartz peak increased. The hydro-separation process focused on the separation of heavy (e.g., native gold) and light (e.g., quartz) minerals from the insoluble residues. After the hydro-separation treatment process, the heavy minerals exhibited typical diffraction lines...
We tried to determine the best conditions for obtaining the uniform homeotropic alignment of fluorinated liquid crystal molecules by using Langmuir-Blodgett technique. 2. Materials and Methods The molecular structure of the compounds investigated is given in Figure 1. The liquid crystals were ...
