Molecular-Weight-Dependent Infiltration and Adsorption of Polymers into Nanochannels
, 2023 The mesoporous silica shell coating hydrogenolysis nano-catalysts alters the molecular weight distributions of cleaved polymer chains compared to catalysts without a shell. The shell, composed of radially aligned narrow cylindrical nanopores, reduces the

Molecular Weight Distribution of Proteins [PDF]
Nature, 1946 THE recent publication1 of an examination of Svedberg's theory of molecular weight distribution, in which the theory is considered to be invalid, suggests that a treatment, similar in some of its details, might be of interest. This was prepared in 19442, and the conclusions agree with those of Johnston, Longuet-Higgins and Ogston1, and with those of ...
