The availability of pure isomers of lactic acid is a key aspect of the fabrication of polymers based on poly-lactic acid with enhanced mechanical and thermal properties. The main problems presented in the fermentation process to d-Lactic acid production are the costs derived from the carbon and ...

Nitrogen-hydrogen (N-H) stretching vibration modes serve as key probes in the identification of the binding strength between amine and hydrogen chloride. Their assignments give us a theoretical viewpoint that could help us select the most suitable solvent for the regeneration of extractant tri-n...

CuFe2O4 samples have been successfully prepared by hydrothermal/solvothermal method under various solvents. The structural, morphological, optical and infrared radiation properties have been systemically investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission el...

In this paper, the measured solubility data and the discussion of thermodynamics for 1-naphthoic acid in common solvents are presented. The gravimetric method was utilized here for obtaining the solubility of 1-naphthoic acid under atmospheric pressure in nine pure and binary mixed solvents from...

Circular polarization of luminescence spectra of human plasminogen and of its derivatives were measured in solutions of ligand-free proteins and with saturating amounts of 6-aminohexanoic acid. Spectroscopic changes induced by the ligand reveal similar perturbations of the binding sites in all t...

An intercalated nanocomposite of the organically modified montmorillonite Cloisite C25A and a degradable poly(ester amide) based on glycolic acid and 6-aminohexanoic acid units (poly(glc-alt-amh)) was prepared using a twin-screw co-rotating extruder. The non-isothermal degradation kinetics was i...

In order to investigate the effect of branching and cyclization in the hydrophobic part of skin permeation enhancers, 17 novel branched-chain and cyclic 6-aminohexanoic acid esters were prepared. Their permeation enhancing activity was evaluated in vitro using human skin and theophylline as a mo...

The crystallization behavior of a new regular poly(ester amide) constituted by glycolic acid and 6-aminohexanoic acid units under both isothermal and non-isothermal conditions is studied. Differential scanning calorimetry (DSC) is used to monitor bulk crystallization, and subsequently Avrami and...

Because histidine-rich glycoprotein binds to the kringle 1-3 domain of plasminogen, it may affect fibrinolysis by reducing fibrin-dependent plasmin production, and in this way it could be mechanistically analogous to 6-aminohexanoic acid. We tested this hypothesis by comparing the effects of his...

In this study, we have synthesized magnetic nanocomposites of magnetite nanoparticles coated with 6-aminohexanoic acid and pectin (MAP). The size of the aqueous dispersion of the nanocomposites was 147 nm with a Polydispersity index (PDI) of 0.32, and the nanocomposites were stable in NaCl up to...

Two potential p-cresol degrading bacterial strains were isolated from petroleum refinery wastewater and identified as Stenotrophomonas sp. (MF004205) strain DBK3 and Bacillus sp. (MF004206) strain DBK4 based on 16S rDNA gene sequencing. While DBK4 was able to utilize p-cresol up to 500 mg L−1 in...

Microalgae is considered the most promising source of oils for biodiesel production. Beside microalgae contain proteins and pigments, which have large applications in the food and pharmaceutical industries. Combining the cultivation of microalgae for the production of these compounds with wastew...

Catalytic ozonation is one suitable method to efficiently remove pollutants from refractory wastewater which if treated improperly could cause the severe contamination of surface and underground water. In this study, nano-mesoporous β-molecular sieves were synthesized and employed as catalysts ...

p-Cresol is a protein-bound uremic retention solute that originates in the intestine through bacterial metabolism and accumulates throughout the body in case of kidney failure. To date, there has been no method to analyze unconjugated p-cresol concentration in the blood with a limit of detection...

In this work, the novel imprinted zeolite (IZ) was synthesized, and its properties and performance in terms of adsorption of p-Cresol, which represent the protein-bounded uremic toxins in aqueous phase under phosphate buffer saline, were studied and compared with the synthesized zeolite-Y (ZeoY-...

To investigate the potential application of Chlorella vulgaris in the treatment of coal gasification wastewater, the characteristics of phenol and p-cresol cometabolism by Chlorella vulgaris were studied, including phenol degradation, ammonia nitrogen removal, antioxidant enzyme activities, and ...

Isobaric vapour–liquid equilibrium (VLE) data for two binary systems of p-Cresol (PC) + diethanolamine (DEA) and m-Cresol (MC) + DEA were measured at 20.0 kPa. The Herington area method was used to check the binary VLE data, and the results showed good thermodynamic consistency. Meanwhile, the ...

Adsorption and reaction of m-cresol on Pt(111) and WOx-modified Pt(111) surfaces was characterized using temperature programmed desorption (TPD), high resolution electron energy loss spectroscopy (HREELS), and X-ray photoelectron spectroscopy (XPS). The results of this study show that on Pt(111)...

The conditions under which the fluorescent pyrazolopyrimidine nucleotide formycin A triphosphate (7-amino-3-(β-d-(5′-tripolyphosphate)ribofuranosyl)pyrazolo[4,3-d]pyrimidine, FTP) forms a 1:1 complex in solution with Tb3+ have been characterized. The complex has a dissociation constant of appr...
