A larger molecule is more polarizable, which is an attraction that keeps the molecules together. They need more energy to escape to the gas phase, so the larger molecule has the higher boiling point. Compare sodium nitrate and rubidium nitrate in terms of molecular weight and boiling point: Fa...
It is interesting to note a particular point represented by a maximum ofRTlnVn. In the case of n-alkanes adsorbed on the catalysts it takes place for a percentage of rhodium %Rh/H-β-Z = 0.75% (Fig.7). However, this maximum of the surface free enthalpy shifts to a percentage %...
The bonding is covalent; however, Oxygen has a much higher electronegativity than Hydrogen. The difference in electronegativity leads to polar covalent bonding between oxygen and hydrogen. The oxygen has a partial negative charge, and the hydrogen atoms are partially positively charged. When you draw...
Analysis of DNA damage by the alkaline comet assay confirmed that under basal conditions p63 þ / À ;p73 þ / À neurosphere cells had accumulated significantly higher levels of DNA damage (Figure 7f). To find if this was due to chromosomal instability, we karyotyped adult SVZ ...
Xfect reagent (cod. 631317; Clontech) and 250 ng of puromycin linear selection marker (cod. 631626; Clontech) according to the manufacturer’s instructions to generate a double-stable cell line expressing both Tet-On 3G transactivator and higher levels of progerin in response to doxycycline (...
