conclusions the present research demonstrated that the ultrasonic (us) process can be utilized as an effective and simple method for treatment of mg dye in an aqueous solution. moreover, the eeo is directly proportional to the mg concentration and power density and inversely proportional to temperature and mechanical agitation, which can be predicted by the obtained empirical kinetics model. co...
A new series of metal-free organic chromophores (TPA-TTAR-A (1), TPA-T-TTAR-A (2), TPA-TTAR-T-A (3), and TPA-T-TTAR-T-A (4)) are synthesized for application in dye-sensitized solar cells (DSSC) based on a donor-π-bridge-acceptor (D-π-A) design. Here a simple triphenylamine (TPA) moiety serves as the electron donor, a cyanoacrylic acid as the electron acceptor and anchoring group, and a novel te...
Mn doped ZnO nanocomposite thin film coated on glass by a simple spin-coating method was used to degrade an azo textile dye from aqueous environment. Mn doped ZnO nanocomposite thin film was characterized by means of X-ray diffraction (XRD) and scanning electron microscopy (SEM). The photo-reduction activity of photocatalyst was evaluated using an azo textile dye as organic contaminant irradiat...
Backgrounds and Objectives: A great part of organic compounds cause more pollution in natural waters meet, are chemical dye material. Azo dyes have more usage in different industries. Azo dyes not only give undesirable dye to the water but also have mutation potential and carcinogenesis effects in human and cause the production of toxic substances in water environments.The purpose of this stud...
Mangosteen peel is an inedible portion of a fruit. We are interested in using these residues as components of a dye sensitized solar cell (DSSC). Carbonized mangosteen peel was used with mangosteen peel dye as a natural counter electrode and a natural photosensitizer, respectively. A distinctive mesoporous honeycomb-like carbon structure with a rough nanoscale surface was found in carbonized ma...
Fluorescent dyes are getting popularity for last few decades due to their extraordinary applications in cell imaging. We have discovered organic Beet root extracted fluorescent (BREF) dye as an efficient pigment for effective cell imaging. By applying this dye to different types of human cells we obtained very good results in fluorescence cell imaging in case of all types of cells. We also have...
This study investigated the effect of temperature, different concentrations of sodium carbonate,and the dose of organic solvent on the desorption of Reactive Red 198 dye from dye-saturated activated carbon using batch and continuous systems. The results of the batch desorption test showed 60% acetone in water as the optimum amount. However, when the concentration of sodium carbonate was raised,...
Abstract A strong coupling regime with dressed states is formed when a propagating surface plasmon (PSP) mode coherently exchanges energy an ensemble of excitons at rate faster than the system’s losses. These are superpositions superradiance and PSP modes, accompanied by remaining subradiance or ‘dark’ exciton states. Dark-states ubiquitous, especially in disordered systems, they rise number as...
