Observations made during occultations cannot provide direct information about atmospheric composition, but they can allow determination of the ratio of mean molecular weight to temperature.
Size exclusion chromatography of deposited polymers is used to relate molecular weight to the monomer-to-initiator feed ratio.
We could not use the fluorescent dye which should be similar molecular weight to methanol, because molecule weight (32.04186 g/mol) of methanol was lower.
The retention volume of the recombinant EBOV NPcore protein in size-exclusion chromatography peaks at 16 mL (Fig. 1A), corresponding to a molecular weight to 35 kDa.
A possible impurity in this raw material which needs to be controlled is the bisfunctional maleimide-PEG, which has a similar average molecular weight to mono-mal-PEG.
The data suggest that our system is one of weak confinement with chain entropy scaling with molecular weight to the 1.1 power (i.e. ∼ N1.1).
It was found that one BCP had PEO blocks with not enough molecular weight to compatibilize the PPO block with the UP thermosetting precursor at room temperature.
By increasing the molecular weight to 9 million, there was a sharp downtrend in injectivity due to the effect of adsorption, and the decrease in permeability, especially near KRA-4430 and BUR-4330, was significant at the late injection phase.
HALS was developed from low-molecular-weight stabilizers to high molecular weight to counteract the effects of volatilization and extraction from the polymer matrix during outdoor application [25, 26].
The resulting biotin-PEG-RGD2 was purified by HPLC, but not using a size-exclusion column because of its similarity in molecular weight to the biotin-PEG-NHS ester.
The two-phase pressure loci at 23 °C and 40 °C are relatively flat and the cloud point pressures increase with PDMS molecular weight to a value of approximately 23 MPa for PDMS 9430.
