Six new azo–azomethine dyes, H 2 L n (n= 1–6), with N 2 S 2 O 2 donor set of atoms have
been prepared via condensation reaction of 1, 10-diaza-4, 7-dithiadecane, I, with substituted …

This paper proposes a method for enhancing diffraction efficiency in an existing grating by re-
illumination of the sample with a secondary pump beam. Though this single-armed pump …

Infrared and Raman spectroscopic analyses were carried out on 1-(4-methoxyphenyl)-4-
methylanthraquinone (1). The interpretation of the spectra was aided by DFT calculations of …

Vibrational intensities are both experimentally measured and theoretically estimated
important physical quantities which are directly related to distributions of the electric charges …

In this paper, we realized two objectives. Firstly, birefringence of azo and anthraquinone dye-
doped nematic liquid crystal (NLC) molecules was investigated by applied electric field …

A indústria têxtil é uma das grandes responsáveis por gerar efluentes, e o tingimento de
poliéster, a fibra mais utilizada atualmente a nível mundial, é um dos principais …

This paper proposes a method for enhancing diffraction efficiency in an existing grating by re-
illumination of the sample with a secondary pump beam. Though this singlearmed pump …

Scientific studies about laser engineering specifically, generation and applications of stable
optical frequency combs, have gained great interest of the scientists due to their intrinsic …
