Molecular interactions studies of methyl cellulose-water solutions using dielectric spectroscopy Phys. Chem. Liq. (IF 1.2) Pub Date : 2023-03-10 Shankar H. Saknure, Nitin P. Garad, Ashwini G. Gubre, Yogesh S. Joshi, Ashok C. Kumbharkhane
ABSTRACT Time Domain Reflectometry (TDR) and frequency domain techniques have been used for the dielectric measurement of methyl cellulose (MC) with water for different concentrations and frequency ranges from 20 Hz to 2 MHz and 10 MHz to 30 GHz at 25°C. The dielectric relaxation in these mixtures can be represented by the Debye relaxation behaviour. The dielectric parameters such as complex permittivity

Elaboration, synthesis and characterisation by conductometric study of chitosan materials in water Phys. Chem. Liq. (IF 1.2) Pub Date : 2023-01-30 Afef Ben Yahya, Emna Cherif
ABSTRACT Biopolymers are common ingredients in medical, technological, and industrial products. This paper presents the experimental analysis of conductometric properties of polysaccharides of chitosan (CH) in solutions in water W. The electrical conductivity was measured under the influence of increasing concentration of (0.5 to 10) g/l and increasing temperature of (288.15 to 318.15) K. The reduced

Characterization and synthesis of materials sodium carboxymethylcellulose (CMC) in water (W) by conductometric study Phys. Chem. Liq. (IF 1.2) Pub Date : 2023-01-29 Hamida Moumni, Emna Cherif
ABSTRACT This paper presents the experimental analysis of conductometric properties of polysaccharide Sodium carboxymethyl cellulose (CMC) in solutions in water W. For the conductometric study of solutions of CMC + W, the electrical conductivity was measured under the influence of increasing concentration of (0.5 g/l to 10 g/l) and increasing temperature of (288.15 to 318.15) K. The reduced electrical
