Evaluation of High Temperature Ripening Ability using the Temperature Gradient Chamber

Temperature gradient chamber for relative growth rate analysis of yeast.

Relative growth is often used as a phenotypic measure to distinguish mutant and wild-type yeast or bacterial strains. Differential growth as a function of temperature is a convenient and accurate means of analyzing differences between strains. Slight differences in the genotypes of two strains frequently result in differential growth of the two strains as a function of temperature. We have deve...

High temperature-gradient refractive index liquid crystals.

We have analyzed the physical origins of the temperature gradient of the ordinary refractive index ( dn(o) /dT) of liquid crystals. To achieve a large dn(o) /dT , high birefringence and low clearing temperature play crucial roles. Based on these simple guidelines, we formulated two exemplary liquid crystal mixtures, designated as UCF-1 and UCF-2, and compared their physical properties with a co...

Evaluation of Barium Sulfate (Barite) Solubility Using Different Chelating Agents at a High Temperature

Barium sulfate (barite) is one of the widely used weighting materials in the preparation of drilling fluid for deep oil and gas wells. Barite is not soluble in the regular solvents; such as, hydrochloric acid (HCl) and other acids. Therefore, in this study, we focused on evaluating the dissolution of the industrial barite particles in different chelating agents. Chelating agents; such as, dieth...

Effect of firing temperature on the properties of inorganic high temperature phosphate adhesive

High-temperature adhesives are considered for high-temperature applications such as the refractory industry. In this research, inorganic high-temperature phosphate-based adhesive was prepared using alumina and micro silica as the main raw materials and monoaluminum phosphate as a binder. The effect of firing temperature on the properties of the adhesive including phases, microstructure, compres...
