Intrinsic Viscosity of Stud Plant Mucilage (Dicerocaryum Zanguebarium): Polymeric Studies at Infinite Dilution.
Abstract: AbstractStudies on stud plant mucilage (SpM) showed that it constitute of galactose, mannose and xylose and it has a molecular weight of 500kDa. However, the behaviour of the polymer using intrinsic viscosity, in dilute regime, has not been explored. The research investigated the intrinsic viscosity of SpM in water, salt and sugar solutions. Salt solutions has poor solvent properties and hence reduced the intrinsic viscosity of SpM as opposed to …

Analysis of the Intrinsic Viscosity Behavior in Polymer Mixtures of Stud Plant Mucilage (Dicerocaryum zanguebarium) with Carboxymethyl Cellulose and Guar Gum: Synergism at Infinite Dilution
Abstract: Compatibility studies of the stud plant mucilage (SpM) with guar gum (GG) and carboxymethyl cellulose (CMC) were elucidated using the following parameters: viscous synergy ( ), interaction index ( ) and enhancement index ( . These parameters were derived from the intrinsic viscosity ( ) obtained from the binary system of SpM–CMC and SpM–GG, measured at 0.05 g/dl. The effects of salt (NaCl) on the binary systems were also investigated …

Determination of Accurate Molecular Weights of Cationic Polyacrylamide Polymers through Advanced Gel Permeation Chromatography Triple Detection Technique
Abstract: AbstractGel permeation chromatography along with refractive index detector or UV detector provides relative molecular weight information along with PDI with respect to standard used. If standards are of different nature than sample such relative results just are used to compare polymers and co-polymers among themselves. These detectors fail to reveal information about other important polymer characters like size of polymer in solution (hydrodynamic volume), branching pattern and intrinsic viscosity which …

Effect of Electrochemically Synthesized Zno/CoO Nanocomposites on Optical, Electrical and Viscosity Properties of Polyvinyl Alcohol Films
Abstract: AbstractZnO/CoO nanocomposites doped poly vinyl alcohol films were prepared by casting method using water as a solvent. X-ray diffraction, IR spectroscopy UV-visible spectroscopy, and scanning electron microscopy techniques were used to characterize the synthesized nanocomposite films. Study of the structural changes and complexation of nanoparticles with polymer matrix were performed using X-ray and IR techniques. Optical characterization studies revealed a blue shift in the absorption edge with increasing nanoparticle concentration …

Free Radical Copolymerization of N-(4-chloro-2-methyl phenyl) Maleimide with Vinyl Monomers and Characterization of Polymers
Abstract: The free radical copolymerization of N-(4-chloro-2-methyl phenyl) maleimide (CMPM) with ethyl acrylate, methyl acrylate and vinyl acetate in THF at 65ºC using free radical initiator was described. The physical characteristics like solubility, intrinsic viscosity and molecular weight were determined and discuss the effect of vinyl monomer in properties of polymers. The structure was ascertained by spectral analysis. The thermal stability of copolymers was evaluated by TGA. Keywords: N-(4-chloro-2-methyl phenyl) maleimide, …

DNA Binding and Cleavage Studies of Cobalt Complexes Containing Bioactive Mixed Ligands
Abstract: The complexes containing bioactive ligand of the type [Co(L1L2)] (PF6)2 complex (1) (where L1=1,10-phenanthroline and L2 = N,N-dimethyl-2-{5-[(pyrrolidin-1-ylsulfonyl)methyl]-1H-indol-3-yl}ethanamine (almotriptan) in 1:1 molar ratio of ligands) and [Co(L1L3L4)] (PF6)2 complex (2) (where L3=4H-1,2,4-triazol-4-amine, L4=1H-benzimidazole-2-thiol and the ligands are in the ratio 1:1:1, were synthesized and characterized. The DNA binding property of the complexes with calf thymus DNA has been investigated using absorption spectra, viscosity measurements and thermal denaturation experiments. The intrinsic …

Advancing Conductive Ink Formulations for DIW with Graphene and Hybrid Nanostructures
Abstract: The development of solvent-based conductive inks for direct ink writing (DIW) has gained significant attention as a pathway toward flexible, wearable, and scalable electronic devices. This review critically examines conductive fillers, binders, solvent systems, and hybrid ink strategies reported in recent literature. Graphene and carbon nanotubes (CNTs) remain the most studied fillers due to their high intrinsic conductivity and unique dimensionality, but challenges such as restacking, bundling, and high viscosity …
