Effects of χ-selenocarrageenan on superoxide dismutase(SOD) activity and protein components (high molecular polymers,HMP)of erythrocyte membranes were studied after rats were given ig χ-selenocarrageenan(140,70 and 35 mg·kg-1.d-1×30d).
Inorganic high polymer flocculant poly-aluminum-ferric-chloride was prepared by mixing treated wastewater 50 mL, HCl (1∶1) 67 mL, NaAlO2 30 g, and FeCl3·6H2O 4 g through refluxing 2 h, with a basicity 68%, Al2O3 9.93% and Fe2O3 0.75%, with suitable pH7~9.
The results show that: under the condition of 1mg/L cation type high polymer floccutant CPAM and pH=8.5,the precipitation rate is quicker and it can precipitate 87.9% in one minute. The density of SS can be controlled in 40mg/L,which reaches the discharge standard of SS.
An operational calculus for the euclidean motion group with applications in robotics and polymer science
We demonstrate these tools in the context of applications in robotics and polymer science.
A partial differential equation from polymer science is shown to be solvable using the operational properties of the Euclidean-group Fourier transform.
At that time, the polymer and plastic industry was in its nascent stage but the industry quickly grew, providing the materials for a large portion of manufactured goods.
Based on the polymer and plastic analogy, the annual market for products that carry nano-components, including all computer chips, half of pharmaceuticals and half of chemical catalysts, will reach $1 trillion by 2015.
Both metalation reaction with n-butyllithium and hydrochlorination reaction with dry hydrogen chloride selectively and quantitatively occurred at the pendant reactive sites, generating polymeric benzyllithium and 1-chloroethylbenzene species.
New approaches to stimuli-responsive polymeric micelles and hollow spheres
This article briefly describes some new approaches to stimuli-sensitive polymeric micelles and hollow spheres, which were developed in the authors' laboratory in recent years.
Generalization of in-situ polymerization method for preparing core-shell polymeric nanospheres and hollow spheres
They were crosslinked in situ via the radical polymerization of the vinyl group initiated by BPO after doping with lithium trifluoromethanesulfonimide (LiTFSI) to give rise to tough polymeric electrolyte films.
