Physicochemical and sweetness behavior of kosmotropic and chaotropic ions in aqueous solutions of polyhydroxy compound.

Hydrated ions have essential applications in biochemical processes. The objective of the present work is to study the behaviour of kosmotropic and chaotropic ions in aqueous solutions of polyhydroxy compounds in terms of sweetness response, volumetric and acoustic parameters such as apparent molar volume (∅), apparent specific volume (ASV), compressibility (∅) etc. at different temperatures 20 °C - 45 °C and 101 kPa.

Investigations to Explore Molecular Interactions and Sweetness Response of Polyhydroxy Compounds with Amino Acids in Aqueous Systems.

In conjunction with the development of people's living standards, the modern world demands good-quality food such as sweets, candies, chocolates, diet drinks, beverages, and so on, but because of obesity and other health issues people concentrate more on sugar-free or low-calorie products. Polyols are such a kind of food with desirable qualities, and they play a role in controlling the blood glucose level in diabetic patients. The density (ρ) and sound speed () of sugar alcohol in water and in (0.

Biosorption of metribuzin pesticide by Cucumber (Cucumis sativus) peels-zinc oxide nanoparticles composite.

Herein, a biosorbent was prepared from cucumber peels modified with ZnO nanoparticles (CPZiONp-composite) for the biosorption of metribuzin. Characterization of the composite was accomplished using FTIR, SEM, EDX, surface area pore size analyzer and pH of point of zero charge (pH). Biosorption study was executed in batch concerning the impact of pH, composite dose, contact time, initial metribuzin concentration and temperature.

Technetium-99m labeled Ibuprofen: Development and biological evaluation using sterile inflammation induced animal models.

In this study we are presenting the development of technetium-99m (Tc) labeled ibuprofen for the imaging of aseptic inflammation. Tc-Ibuprofen complex was developed by optimizing the radiolabeling conditions such as reaction time, ligand and reducing agent concentration, pH, reaction time and temperature. Following the addition of 600 µg of ibuprofen, 4 µg of stannous chloride as reducing agent and 300 MBq Tc radioactivity; the pH of reaction mixture was adjusted to 11 and allowed to react for 15 min at room temperature.

Synthesis, Spectral investigation (¹H, ¹³C) and Anti-microbial Screening of benzophenone imines.

New series of benzophenone imines with general formula Ph2-C=NR; R = Benzyl, 4-Fluorobenzyl, Naphthyl, Phenyl, 4-Nitrophenyl were synthesized by condensation of dichlorodiphenylmethane and different aromatic primary amines (1:1) Those imines were characterized by different physiochemical and spectroscopic techniques like melting point, elemental analysis, FT-IR, multinuclear NMR (¹H, ¹³C). After characterization, imines were subjected to anti-microbial activities. All compounds showed promising activity against different bacterial strains like Escherichia coli, Bacillussubtilis, Pasturellam ultocida and Staphylococcus aureus as well as fungal strains like Alternata alternaria, Ganoderma lucidium, Penicillium notatum and Trichoderma harzianum using Amoxicillin and Flucanazole as a standard drugs respectively.

Acoustical behavior of some amino acids in aqueous disodium citrate solutions over temperature range (298.15-313.15) K.

Sound velocity, U, and density, ρ of some amino acids viz. glycine, methionine, phenylalanine and tryptophan were determined in 0.1, 0.

Volumetric and acoustical behaviour of sodium saccharin in aqueous system over temperature range (20.0-45.0)°C.

Densities and ultrasonic velocity values for aqueous solutions of sodium saccharin (SS) has been measured as a function of concentration at 20.0-45.0 °C and atmospheric pressure using DSA-5000 M.

Solution behaviour and sweetness response of D-Mannitol at different temperatures.

The solution properties of d-Mannitol (DM) were studied to explore sweetness response and molecular interactions in aqueous solutions at different temperatures. The density (ρ) and ultrasonic velocity (μ) were measured at 20-45°C using density sound velocity metre (DSA 5000M). The results obtained were used to compute apparent and partial molar volume, apparent specific volumes, partial molar expansibility, apparent molar isentropic compressibility and compressibility hydration number.

Studies on molecular interactions of some sweeteners in water by volumetric and ultrasonic velocity measurements at T=(20.0-45.0°C).

Densities and ultrasonic velocity values for aqueous solutions of two sweeteners viz., maltose monohydrate and acesulfame-K have been measured as a function of concentration at 20.0-45.

Preparation of rich handles soft cellulosic fabric using amino silicone based softener. Part-I: Surface smoothness and softness properties.

A series of amino silicone based softeners with different emulsifiers were prepared and adsorbed onto the surfaces of cotton and blends of cotton/polyester fabrics. Factors affecting the performance properties of the finished substrate such as post-treatment with amino functional silicone based softener varying different emulsifiers in their formulations and its concentration on different processed fabrics were studied. Fixation of the amino-functional silicone softener onto/or within the cellulose structure is accompanied by the formation of semi-inter-penetrated network structure thereby enhancing both the extent of crosslinking and networking as well as providing very high softness.
