Fe (II) forms a coloured ternary complex with SCR in presence of 1,10-Phen which have molar absorptivity of 3.56x104 mole-1 cm-1 at pH 5.0 and λmax 520 nm. The complex contains three molecules of 1,10-Phen coordinated to Fe (II) ion and one molecule of SCR through ion association giving the overall formula Fe (II) (SCR) (Phen)3. Beer’s law range is 0.0223-1.6084 ppm and Sandell’s sensitivity 0....

A Spectrophotometric investigation was applied on the complexation of 1,3-bis (3-(2-pyridyl) pyrazol-1-ylmethyl) benzene (1,3-PPB) and 1,4-bis (1,4-PPB) with Zn(II) Cd(II) ions in a mixed (1:1) solvent water ethanol. The mole ratio methodology used to calculate stoichiometry, molar absorptivity, stability constant values. Some experimental conditions have been investigated, including pH, ionic ...

The emissivity and absorptivity of radiation by matter are fundamental physical parameters required to adequately simulate inertial confinement fusion experiments. We present novel neural network models for predicting these interaction coefficients. This research extends the methods used Kluth et al. (2020) that made similar predictions a single chemical element, krypton. Our based on fully-con...

This study focuses on the influence of alloying elements (Si and Mg) process parameters laser powder bed fusion (LPBF) processability aluminum (Al). In this regard, pure Al, AlSi12, AlSi10Mg parts with without single tracks their top surface were fabricated using a wide range parameters. The oxidation tendency, absorptivity, attributes evaluated to justify densification level processing window ...

Introduction of S-ethyl groups in all four ortho positions of azobenzene prevents reduction of the azo group by intracellular glutathione, while enhancing the absorptivity to ~10,000 M(-1) cm(-1) in the blue and green regions of the visible spectrum. cis-to-trans isomerization occurs thermally on the minutes timescale. Further, this substitution pattern permits switching with red light, a color...
