Accelerated chemical degradation of polyacrylamide - Gao
The chemical degradation of polyacrylamide(PAM) at low temperature in aqueous medium was initiated by peroxides. The degradation degree of the polymer rose with the reaction time. The degradation degree of PAM depended not only on peroxide characteristic but also on the concentration of polyacrylamide and potassium persulfate, degradation

Enzymatic degradation of polyacrylamide in aqueous
The enzymatic degradation of konjac glucomannan (KGM) was conducted using β-mannanase from an alkalophilic Bacillus sp. in the aqueous medium (pH 9.0) at 30°C.

Degradation on polyacrylamides. Part II. Polyacrylamide
1. Introduction. Polyacrylamide (PAAm) gel networks are formed in an aqueous medium and are widely used in electrophoresis for protein separations or as membranes for protein isolations or blood purifications. Because these hydrogels are used in some applications where human contact is involved, the products are required to be either non-toxic and/or biocompatible.
In this work, we review the publicly available literature on the microbial degradation of polyacrylamide and its deamination product polyacrylate. To our knowledge, biotic polyacrylamide degradation has been described only very briefly in two recent reviews ( Guezennec et al., 2015 ; Joshi and Abed, 2017 ).
US5843763A - Dehalogenation of organohalogen-containing
Enzymatic dehalogenation of undesirable nitrogen-free organohalogen compounds is carried out by adding a dehalogenase to an aqueous composition comprising a nitrogen-free organohalogen compound and a nitrogen-containing cationic polymer. The enzymatic dehalogenation of the nitrogen-free organohalogen compound is achieved without any substantial effect upon the nitrogen-free organohalogen compound.

Mitochondrial Myopathy with a Defect of Mitochondrial
The clinical and biochemical heterogeneity of the mitochondrial myopathies is now well established.1 , 2 Recent work has focused on identifying the molecular basis of these disorders and has demons...
In this review, a comprehensive overview of advances in the supramolecular complexes of carbohydrates and poorly soluble drugs is presented. Through the complexation process, poorly soluble drugs could be efficiently delivered to their desired destinations. Carbohydrates, the most abundant biomolecules, have diverse physicochemical properties owing to their inherent three-dimensional
Discovery of 2-[5-(4-Fluorophenylcarbamoyl)pyridin-2
The G protein-coupled chemokine receptors CXCR1 and CXCR2 play key roles in inflammatory diseases and carcinogenesis. In inflammation, they activate and recruit polymorphonuclear cells (PMNs) through binding of the chemokines CXCL1 (CXCR1) and CXCL8 (CXCR1 and CXCR2). Structure–activity studies that examined the effect of a novel series of S-substituted 6-mercapto-N-phenyl-nicotinamides on
Although a large body of research has been devoted to biomaterial development for bone tissue engineering and related medical disciplines in the last few years, novel and optimized materials especially for bone fractures of critical sizes demand continued development. In this respect, polysaccharide-based hy
- What types of solvents are used as corrosion inhibitors?
- Examples of such types of solvents include water, ILs, polyethylene glycol (PEG) and supercritical CO2. In the literature, numerous chemicals derived from these solvents are widely used as environment-friendly corrosion inhibitors.
- Are thiopyrimidine derivatives effective corrosion inhibitors for mild steel in hydrochloric acid?

- Can irradiation be used as an alternative to toxic corrosion inhibitors?
- Currently, compounds derived through multicomponent reactions (MCRs), mechanochemical mixing (MCM), and solid supported syntheses (SSSs) and chemicals derived through microwave (MW) and ultrasound (US) irradiations are widely used as environment-friendly alternatives to traditional toxic corrosion inhibitors.
- Are mw/US irradiations a corrosion inhibitor?
- The literature study shows that numerous environment-friendly alternatives derived from MCRs and MW/US irradiations are tested as corrosion inhibitors; however, the implementation of such types of chemicals should be further enhanced.
