As a potent antibacterial, antifungal or antiviral material, synthesis of quaternarized epoxidized soybean oil was demonstrated in this work. The first step the is reaction (ESO) with 2-chloroethyl maleic acid (Cl-MA-ESO). last quaternarization condensate triethylamine (Q-MA-ESO). All synthesized monomers were characterized by FTIR and 1H NMR techniques. Homopolymer derivative (Q-MA-ESO) not ob...

The complete sequence-specific assignment of the 15N and 1H backbone resonances of the NMR spectrum of recombinant human interleukin 1 beta (153 residues, Mr = 17,400) has been obtained by using primarily 15N-1H heteronuclear three-dimensional (3D) NMR techniques in combination with 15N-1H heteronuclear and 1H homonuclear two-dimensional NMR. The fingerprint region of the spectrum was analyzed ...

The biodegradation and hydrolysis rates of an aliphatic aromatic copolyester were measured in manure, food, and yard compost environments and in phosphate buffer solution (pH 1⁄4 8.0) and vermiculite at 58 C. Mineralization, molecular weight reduction, and structural changes determined by DSC, FTIR, and 1H NMR were used as indicators of the biodegradation and hydrolysis rates. Poly(butylene adi...

In this research a chemical modification of kraft lignin was carried out using basic nucleophilic substitution reaction (NSA) in order to functionalize it as novel crosslinking agent for the synthesis active hydrogels. The success synthesized crosslinker demonstrated by several techniques such volumetry probes, FTIR, 1H-NMR and DSC. Thus, obtained materials were employed during acrylic acid-bas...

The 1:1 cocrystal of 2-amino-4-chloro-6methylpyrimidine (2A4C6MP) with 4-methylbenzoic acid (4MBA) (I) has been prepared by slow evaporation method in methanol, which was crystallized in monoclinic C2/c space group, Z = 8, and a = 28.431 (2) Å, b = 7.3098 (5) Å, c = 14.2622 (10) Å and β = 109.618 (3)°. The presence of unionized –COOH functional group in cocrystal I was identified both by spectr...

Segmented linear polyurethanes (PUs) containing Diels-Alder (DA) adduct were synthesized in toluene solution from poly("-caprolactone) (PCL, Mn = 10, 25 and 50 kg/mol), diisocyanate (methylene diphenyl diisocyanate (MDI), 2,4toluene diisocyanate (TDI), 1,6-hexamethylenediisocyanate, (HDI)), furfurylamine (FA) and bismaleimide (BMI). The order of the segments in the PUs was -PCL-MDI-FA-BMI-. The...
