STUDIES ON CONCENTRATED RUBBER SOLUTION I

Studies on Myoglobin I. the Solwility of Myoglobin in Concentrated Ammonium Sulfate Solutions

The crystallization by Theorell (8) of one of the hemoglobins of muscle, horse heart myoglobin, has made possible the more accurate study of this interesting protein, and opened the way for the investigation of other members of the series. Previously the question of the existence of a protein in the muscle resembling, but nevertheless distinct from, blood hemoglobin was in doubt. Theorell’s wor...

Concentrated Solution of Lecithin in Kahn

studies on properties of short fiber reinforced natural rubber composites

natural rubber/fiber composites were prepared in a laboratory mixer using new and waste short nylon fiber by a one-step mixing process. fiber loading and bonding agent effects on the microstructure and mechanical properties of the composites were studied. the cure characteristics of composites were investigated by using rheometer. cure and scorching times of the composites decreased while maxim...

Solution structural studies of the Ag(I)-DNA complex.

We report equilibrium dialysis and electric dichroism studies of the two strong complexes (I and II) of silver ion with DNA. Cooperative conversion of DNA to the stronger type I complex results in a 9% length decrease, and a structure in which intercalated ethidium is perpendicular to the helix axis. Upon addition of more Ag+ to form the type II complex, the DNA length reverts to its original v...

One-pot facile synthesis of a concentrated Si nanoparticle solution.

A silicon nanoparticle solution (size ≅ 50 nm) with the concentration of 100 mM, which is contamination free, was synthesized using a ball milling method and was stable for 4 months without aggregation. This stability was responsible for large negative zeta potential on the surface of Si-NPs, established by milling in 2-propanol solvent.
