A 1D anionic lanthanide coordination polymer {[(CH(3))(2)NH(2)] [(H(2)abtc)(2)Ho(H(2)O)]}n () (H(4)abtc = 3,3',5,5'-azobenzene-tetracarboxylic acid) has been synthesized under hydrothermal reaction conditions. The protonated [(CH(3))(2)NH(2)](+) is generated from decomposed DMA during the reaction, and balances the negative charge of the framework. The as-obtained samples were characterized usi...

The presence of synthetic industrial dyes in the environment poses significant risks to aquatic ecosystems, human health, and economies. This study aims synthesize iron oxide nanoparticles (IONPs) using a green method, analyze them physicochemical techniques, examine effectiveness with which they photocatalytically degrade crystal violet dye sunlight. Fourier transform infrared spectroscopy (FT...

The study investigated the waste beet pulp shreds for use as a sorbent removing crystal violet dye from aqueous solutions and investigating antimicrobial properties of obtained material. During preparation BPSCV (beet with adsorbed violet) material, equilibrium kinetic studies (CV) sorption process on BPS were carried out. tests allowed selection best-fitted isotherm model determination capacit...

Ferula orientalis L. stalks were used as an agricultural solid biomass waste for preparation of activated carbon with zinc chloride activation using slow pyrolysis in a fixed-bed reactor. The chemical characteristics of the activated carbon obtained at 550 C were identified by elemental, fourier transform infrared spectroscopy, Brunauer–Emmett–Teller, scanning electron microscopy analyses and f...

In contemporary research, “Heterostructure” assemblies play an important role in energy conversion systems, wherein the composite assemblies facilitate faster charge carrier transport across the material interfaces. The improved/enhanced efficiency metrics in these systems (electro/photo-electrochemical processes/devices) is due to synergistic interaction and synchronized charge transport a...

The results 1 from measurements made with the glass electrode and spectrophotometer show that brilliant cresyl blue penetrates as free base into the vacuoles of living cells of Nitella. The present paper describes similar experiments with azure B, methylene blue, and crystal violet. Since the methods for the condition of cells, extraction of the sap, penetration experiments, extraction of free ...

Synthesis of zeolite from kaolinite clay is a very promising process, requiring thorough beneficiation and calcinations to obtain purer monomer. Kaolinite clay sourced from Kankara, Nigeria is associated with inherent impurities, making its transformation rather challenging. The addition of dye, though, assisted in inhibiting the negative effects of impure phases on the desired end products and...

Twenty four reference strains and 112 clinical isolates of coagulase negative staphylococci (CNS) were examined for their reactions in the crystal violet test. Some species gave a white reaction and others a purple reaction. Results were consistent and reproducible and each species gave only one pattern of crystal violet reaction. Within the limited variety of species represented in the clinica...
