The Efficacy of New Liquid Laser Dye Material – Chalcone: 1-(4-methylsulfonyl phenyl)-3-(4-N,N-dimethyl (amino phenyl)-2-propen-1-one (MSPPP)

This paper includes the efficacy of synthesis and characterization of a new liquid laser dye material – chalcone of 1-(4-methylsulfonyl phenyl)-3-(4-N,N-dimethyl (amino phenyl)-2-propen-1-one (MSPPP) and its application as a new laser medium. The absorption and fluorescence spectra of MSPPP were investigated under different solvents and concentrations. The study investigated the pump pulse energies of Nd: YAG laser (355 nm) and the amplified spontaneous emission (ASE) performance of MSPPP under various concentrations, and organic solvents. At identical conditions, the amplified spontaneous emission spectra of MSPPP in solution were compared with a conventional laser dye of coumarin 503. The fluorescence quantum yield and the gain of MSPPP were determined. The features are: (I) MSPPP has stellar photochemical stabilization., (II) ASE from the MSPPP was setting in the wavelength range between 515 and 548 nm. The molecular geometry was optimized and their HOMO– LUMO energy values were determined by SCM Software for Chemistry & Materials using DFTB (GGA BLYP) [Density-Functional based Tight-Binding] method

Optical properties and efficiency studies for Beta Vulgarize, Curcuma Longa and Vulgaris var. cicla dye sensitized solar cell

The sun light, that gives the clean, fleckless and cheap energy which is an environmental friend; becomes the demand and on-call of the researchers in the last century.  In this paper, the three natural dyes, namely; (Beta Vulgarize, Curcuma Longa and Vulgaris var. cicla) were successfully and swimmingly synthesized by dissolved in acetone solvent. The optical properties; absorbance, transmission, reflection, absorption coefficient and energy band gap were carefully and solicitously studied using ultra violet visible spectrometer UV.vis. The vibration modes for the three samples were also determined and delimited using Fourier Transform Infra-red spectroscopy FTIR. The efficiency of dye sensitized solar cell DSSC was studied using and utilisation IV characteristic for three natural dyes  (Beta Vulgarize, Curcuma Longa and Vulgaris var. cicla), where the cell was fabricated and processed by coating a conducting proceeding substrate of (FTO) using titanium dioxide TiO2.  The power conversion efficiency was calculated and reckoned, which found to be [0.583, 0.539 and 0.285], respectively. The highest efficiency obtained from this DSSC sensitized by Beta Vulgarize which was 0.583%, and thus might be due to its concentrated, focussed dye and colour.&nbsp

Influence of Rice Concentration on the Physical Properties of Gum Arabic/Rice Composite Material

Abstract In this work, Gum Arabic (GA)/ Rice composite materials were prepared using solid state reaction method. Four samples of GA with different concentrations of Rice, (0.0, 0.1, 0.2 and 0.3g) were considered. Fourier Transform Infra Red Spectroscopy (FTIR) and Ultraviolet-Visible spectroscopy (UV-visible spectroscopy) were used as analytical techniques. The optical properties of the prepared samples were determined including Energy gap and Absorption. The FTIR spectra of GA showed a broad and strong absorption band in the range 500-3500 cm-1, and these absorptions were assigned to the different stretching vibrations. The wavelengths of the samples were found to decreased when Rice concentration was increased and found in the range 221.2 and 225.4 nm, while the absorptions were found in the range 2.74-3.39 a. u. The energy band gab was calculated and was found to be in range 5.08 -5.21 eV. The effect of doped with Rice was profound in the properties of GA as the absorption and energy band gap were found to increase with Rice concentration

Structural Characterization and Physical Properties of Syzygium cumini Flowering Plant

ABSTRACT: In this study, the flowering plant of syzygium cumini was used. X-ray fluorescence (XRF) and X-ray diffraction (XRD) were used to investigate the structure of the leaves and barks of syzygium cumini. The XRD results were indicated that the structures of both leaves and bark were amorphous. The XRF results indicated that both leaves and barks contained Potassium (K), Calcium (Ca), (Ti), and Magnesium (Mn), Iron (Fe), Copper (Cu), Zinc (Zn), Zernike (As), Lead (Pb), Barium (Br), Strontium (Sr). The optical properties of syzygium cumini were carried out using Fourier Transformation infrared spectroscopy (FTIR) and Ultra violet spectroscopy (UV). The FTIR spectra showed a broad and strong absorption band in the range (685-1638) cm -1 , and these absorptions were assigned to the different stretching vibrations. The absorption for bark and leave was found to be 2.45 and 2.52 a u, while the wave length was found to be 277.4 and 277.5 nm, respectively. The energy band gap is calculated and found to be 5.017 and 4.67 eV, for bark and leave, respectively

Development of new thiazolidine-2,4-dione hybrids as aldose reductase inhibitors endowed with antihyperglycaemic activity: design, synthesis, biological investigations, and in silico insights

This research study describes the development of new small molecules based on 2,4-thiazolidinedione (2,4-TZD) and their aldose reductase (AR) inhibitory activities. The synthesis of 17 new derivatives of 2,4-TZDs hybrids was feasible by incorporating two known bioactive scaffolds, benzothiazole heterocycle, and nitro phenacyl moiety. The most active hybrid (8b) was found to inhibit AR in a non-competitive manner (0.16 µM), as confirmed by kinetic studies and molecular docking simulations. Furthermore, the in vivo experiments demonstrated that compound 8b had a significant hypoglycaemic effect in mice with hyperglycaemia induced by streptozotocin. Fifty milligrams per kilogram dose of 8b produced a marked decrease in blood glucose concentration, and a lower dose of 5 mg/kg demonstrated a noticeable antihyperglycaemic effect. These outcomes suggested that compound 8b may be used as a promising therapeutic agent for the treatment of diabetic complications
