A new phenomenon in flow birefringence of solutions of macromolecular substances

Journal of Polymer Science, 1953
AbstractMeasurements on flow birefringence of solutions of polyvinyl chloride in cyclohexanone revealed that the angle of orientation increases with decreasing concentration of the solution. That this surprising effect was not due to constructional or experimental errors was demonstrated by results obtained with polystyrene, which were in agreement ...

Chitosan based macromolecular hydrogel loaded total glycosides of paeony enhances diabetic wound healing by regulating oxidative stress microenvironment.

International Journal of Biological Macromolecules, 2023
Oxidative stress microenvironment caused by reactive oxygen species (ROS) accumulation seriously hinders wound healing in diabetes, which brings great burden to global health. Various wound dressings on the market focus on delivering active substances to

Relationships between Viscosity and the Contents of Macromolecular Substances from Milk with Different Storage Styles

Food Science and Technology (United States), 2016
Relationships between viscosity and the contents of macromolecular substances (milk protein, casein, whey protein and milk fat) from raw milk were studied at the temperature of 2-5 o C (a storage temperature in a household refrigerator), 10 o C and 20 o ...

Imaging of Humic Substance Macromolecular Structures in Water and Soils

Science, 1999
Humic substances (HSs) are the natural organic polyelectrolytes formed from the biochemical weathering of plant and animal remains. Their macromolecular structure and chemistry determine their role in biogeochemical processes. In situ spectromicroscopic evidence showed that the HS macromolecular structures (size and shape) vary as a function of HS ...
