Negative effect of clay fillers on the polyvinyl alcohol biodegradation: technical note

This work focuses on polyvinyl alcohol (PVA) biodegradation in the presence of mineral clays in an aqueous aerobic environment. PVA with a degree of hydrolysis of 88% and 72% was used for the experiments. The selected group of mineral clays (nanofillers for polymers) of montmorillonite (MMT) Cloisite (R) Na+; organo-modified montmorillonite (OMMT) Cloisite (R) 20A, Cloisite (R) 30B; waste kaolin; kaolin; and zeolites were prepared by synthesis of the aforementioned kaolins. The level of biodegradation was measured using a respirometer, Micro-Oxymax, and evaluated according to CO2 production. Results of this test indicate a negative effect on PVA biodegradability in the presence of MMT Cloisite (R) Na+ and Cloisite (R) 30B. It has been found that PVA biodegradability in the presence of no adapted inoculum was adversely affected by the biocidal effects of the organic modifier of Cloisite (R) 30B. In this case, PVA 88-8 biodegradation decreased by 71% and PVA 72-10 biodegradation dropped by 58%. Furthermore, the sorption of PVA on the Cloisite (R) Na+ in the range of 40%-45% was demonstrated in the following research.Tomas Bata University in Zlin [IGA/FT/2018/009]; Ministry of Education, Youth, and Sports of the Czech Republic [LO1504

PVP Based Materials: Biodegradation in Different Environments

The research deals with biodegradation of films prepared from polyvinylpyrrolidone and polylactic acid (PVP/PLA). Biodegradation of PVP/PLA films was supported by the following additives: 1-methyl-2-pyrrolidone, 1-octyl-2-pyrrolidone, acrylamide and N-acetyl-L-phenylalanine according to the previous study. The films were prepared by a solvent casting technique. Biodegradation was observed using the respirometric method in different environments. The films subjected to biodegradation were analyzed by scanning electron microscopy and Fourier transform infrared spectroscopy. It was found that the films are substantially degraded, but not in the biological way; PVP was quickly removed in presence of water because of its easy solubility. In contrast, this fact could support biodegradation of PLA, which becomes more available for microorganisms when PVP leaves PLA matrix. © 2017 by Marketa Julinova.Tomas Bata University in Zlin [IGA/FT/2017/003]; projects of Ministry of Education, Youth, and Sports of the Czech Republic within the NPU I program [LO1504

Modeling of the partial oxidation of glycerol by estimation of its transfer function

The reaction pathway for the conversion of glycerol into different products, namely glyceraldehyde, glyceric acid, glycolic acid, mesoxalic acid and tartronic acid was studied by means of electrochemistry. Multiple Pulse Amperometry technique was used to control the potential during the electrooxidation reaction. The estimation of the transfer function was realized on the basis of dynamic models for the oxidation reaction. The equations obtained in the s-domain were expressed in the time domain using Inverse Laplace transformation to describe the variation of glycerol and products concentration.Ministry of Education, Youth and Sports of the Czech Republic within the National Sustainability Programme [LO1303 (MSMT-7778/2014)]; European Regional Development Fund under the project CEBIA-Tech [CZ.1.05/2.1.00/03.0089

Hydration and barrier potential of cosmetic matrices with bee products

Honey, honey extracts, and bee products belong to traditionally used bioactive molecules in many areas. The aim of the study was primarily to evaluate the effect of cosmetic matrices containing honey and bee products on the skin. The study is complemented by a questionnaire survey on the knowledge and awareness of the effects and potential uses of bee products. The effect of bee molecules at various concentrations was observed by applying 12 formulations to the skin of the volar side of the forearm by non-invasive bioengineering methods on a set of 24 volunteers for 48 h. Very good moisturizing properties have been found in matrices with the glycerin extract of honey. Matrices containing forest honey had better moisturizing effects than those containing flower honey. Barrier properties were enhanced by gradual absorption, especially in formulations with both glycerin and aqueous honey extract. The observed organoleptic properties of the matrices assessed by sensory analysis through 12 evaluators did not show statistically significant differences except for color and spreadability. There are differences in the ability to hydrate the skin, reduce the loss of epidermal water, and affect the pH of the skin surface, including the organoleptic properties between honey and bee product matrices according to their type and concentration.Internal strategic project of Tomas Bata University in Zli

Electrooxidation of glycerin by potential sweep technique and controlled potential electrolysis

In this study, potential sweep technique and controlled potential electrolysis were used to analyze the electrochemical oxidation of glycerin in a three electrode system using platinum as a working electrode. Electrochemical experiments were performed at different concentrations of glycerin and manganese dioxide (0.015-0.124 M) to analyze the reaction order of reactant and oxidant. Voltammograms were studied at different positive and negative potential limits (-1.5 to 1.5 V vs Ag/AgCl), sweep rates (0.01 to 0.08 V/s) and temperatures (27 to 60 °C). The influence of each parameter on the voltammogram shape is discussed. Prolonged electrolysis at controlled potential yield glyceraldehyde, glyceric acid and glycolid acid as the main products.European Regional Development Fund under the Project CEBIA-Tech [CZ.1.05/2.1.00/03.0089]; Tomas Bata University Internal Grant [IGA/FAI/2014/011/]; National Council of Science and Technology (CONACYT) in Mexico [214734]; Tomas Bata University in Zli

Effect of hydrothermal treatment on the structure of an aluminosilicate polymer

The effect of hydrothermal treatment on the structure of an aluminosilicate polymer prepared by a polycondensation reaction between silicate and hydroxoaluminate in alkaline aqueous solution was studied. The structural changes were investigated using X-ray diffraction analysis, Fourier-transform infrared spectroscopy, scanning electron microscopy imaging and thermogravimetric analysis. The results indicated that the amorphous aluminosilicate polymer transformed into a crystalline product during the hydrothermal treatment at 145A degrees C. The crystalline phase was identified as a mineral of the zeolite group, most likely phillipsite. This transformation required an alkaline environment during the hydrothermal treatment
