ABSTRACT A systematic understanding of the non‐covalent interactions that influence the structures of the cis conformers and the equilibrium between the cis and the trans conformers, of the X‐Pro tertiary amide motifs, is presented based on analyses of 1H‐, 13C‐NMR and FT‐IR absorption ...

ABSTRACT A new approach in kinetic modeling of thermo‐oxidative degradation process of starch granules extracted from the Cassava roots was developed. Based on thermo‐analytical measurements, three reaction stages were detected. Using Weibull and Weibull‐derived (inverse) models, it was ...

Abstract Extension vs. twist data of Koster et al. (ref. 43) are analyzed to obtain C for the main chain segments and the twist energy parameter (ET) for the supercoiled pseudocircular (sp) domain(s), from which C is estimated via simulations. The torsional rigidity in the tension‐free sp ...

ABSTRACT The charged nanocomposite hydrogels (NC gels) were synthesized by copolymerization of positively or negatively chargeable monomer with N‐isopropylacrylamide (NIPAm) in the aqueous suspension of hectorite clay. The ionic NC gels preserved the thermo‐responsibility with the phase ...
