The phase behaviors of carbon dioxide (CO2)/tetramethyl orthosilicate (TMOS)/poly(methyl methacrylate) (PMMA) and CO2/TMOS/poly(styrene) (PS) ternary systems were measured. The measurements were performed using a synthetic method involving observations of the bubble point and cloud point. The phase boundaries were measured at temperatures ranging from 313.2 K to 393.2 K and CO2 weight fractions ranging...
The phase behaviors of carbon dioxide (CO2)/trimethoxy(methyl)silane (MTMS) and CO2/Methylsilicate 51 (MS-51: methylsilicate tetramer) binary systems were determined. The experiments were performed using a synthetic method by observing the bubble point. The phase boundaries were determined at temperatures of 313.2 K–393.2 K and CO2 molar fractions of 0.2–0.9. The experimentally obtained bubble points...
The family A DNA polymerases from thermophilic bacteria are useful for PCR. The DNA polymerase from Thermus aquaticus (Taq polymerase) was the original enzyme used when practical PCR was developed, and it has remained the standard enzyme for PCR to date. Knowledge gained from structure-function relationship studies of Taq polymerase is applicable to create PCR enzymes with enhanced performance. We...
