Preparation and characterization of oxidized wheat starch with hydrogen peroxide as an environmentally friendly oxidant
(7th Conference of the Young Chemists of Serbia, 2019)
The starch oxidation involves oxidation of primary or secondary hydroxyl to carbonyl
or carboxyl groups, whereas the number of these groups indicates the level of oxidation.
Oxidized starch is used as surface sizing agent ...
Hybrid denture acrylic composites with nanozirconia and electrospun polystyrene fibers
(Public Library Science, San Francisco, 2019)
