Hydrolysis of the lignocellulosic biomass results in release high-value chemicals that during industrial processing can be recovered with membrane technologies. To maintain an effective performance membranes used technological biomass, their regular cleaning is essential. Although several guidelines may found for cases organic fouling, data fouled by hydrolyzed limited. Current research aimed t...

El cultivo de anteras es una herramienta que permite la producción plantas homocigotas doble haploides y alternativa viable apropiada para el mejoramiento cultivos. Sin embargo, éxito su aplicación depende diversos factores afectan eficiencia. Por ello, objetivo del estudio fue determinar los estadios las microsporas asociadas con desarrollo botones florales, así como evaluar métodos esteriliza...

Asphalt rubber shows good road performance. However, the compatibility and aging problems of asphalt limit its application. The improvement solubility crumb in was investigated this research, mechanism effect on rheological properties activated studied. First, by using a sodium hypochlorite (NaClO) solution, pore characteristics microstructure were analyzed. Second, influence rubber’s activatio...

TEMPO/NaBr/NaClO-mediated surface oxidation of NCC, acid-extracted from aspen kraft pulp, was studied, and the properties of nanocellulose whiskers before and after oxidation were characterized by conductimetry, Fourier transform infrared spectroscopy, X-ray diffraction, and atomic force microscopy. The resulting products with varied oxidation degrees were then applied in the deinked pulp to ev...

The sulfonated tripodal polyaza-polycatechol-amine ligand tris(2,3-hydroxy-5-sulfobenzylamine) ethyl)amine (STRENCAT) was synthesized and its protonation constants determined by potentiometry at 25 degrees C and in 0.1 mol dm(-3) NaClO(4). In the adopted experimental conditions (2.5 < p[H(+)] < 11.5), six of the virtual thirteen protonation constants of STRENCAT were determined. The deprotonati...

We attached anti-human serum albumin (anti-HSA) affibody ligands on bacterial cellulose (BC) by EDC– NHS-mediated covalent conjugation and physical adsorption and demonstrate their application for tubular biofiltration of blood proteins. The BC fibrils were first modified by carboxymethyl cellulose (CMC) by incorporation of CMC in the BC culture medium, producing in situ a CMC–BC tubular networ...

In this study, granular activated carbon, GAC, was modified by oxidation with H2O2 and NaClO aqueous solutions and heat treatment at 900 °C. The N2 adsorption isotherms at −196 °C and SEM and FTIR results were used to characterize the properties of the prepared ACs. Textural parameters such as BET surface area and pore volumes were assessed by gas adsorption. The BET surface area values of soli...

The acid-base properties of N,N9-disubstituted dithiooxamides derived from alkyl-a-aminoacids or glycylglycine were studied in aqueous solutions of pH 2.5-10.8. For each dithiooxamide, protonation constants were obtained from potentiometric data for three dilute aqueous solutions [I50.15 M (NaClO ), 37.08C] using the program HYPERQUAD, and are reported as conventional pK values. For 4 a compoun...
