Thermoplastic sugar beet pulp (thermo-mechanical processing was discussed in previous studies) was formed into film strips by extrusion. Film tensile properties are discussed according to the molecular structure of external plasticizer. Sorbitol, fructose and adipic acid have a marked antiplasticizing effect, while urea and xylitol gave higher ultimate tensile stress than glycerol for a compara...

practically all important properties of the agricultural products, the foods and the biological objects. Among the properties, the important role is played bymechanical properties including the viscoelastic ones. These properties are influenced mainly by temperature and the strain rate but water plays the role of the main plasticizer in the controlling mechanisms. The relative simple models wer...

A renewable resource, epoxidized jatropha oil (EJO), was used as a green plasticizer and added to poly(lactic acid) (PLA). EJO was compounded into PLA at different contents. The addition of 3 wt % EJO to the PLA demonstrates significant improvement in flexibility, which leads to a percentage increase of about 7000% in elongation at break. This tensile result was confirmed by surface morphology ...

The aim of this work was to develop a pulsatile release system with metoprolol for chronotherapeutical use by coating swellable mini-tablets with Eudragit RS. To study the influence of the formulation factors (amount of coating polymer, plasticizer percentage in film coating and swelling agent percentage in mini-tablets), a Box-Behnken design of experiment (DoE) was used. To evaluate the influe...

A lipase from Thermomyces lanuginosus and cutinases from Thermobifida fusca and Fusarium solani hydrolysed poly(ethylene terephthalate) (PET) fabrics and films and bis(benzoyloxyethyl) terephthalate (3PET) endo-wise as shown by MALDI-Tof-MS, LC-UVD/MS, cationic dyeing and XPS analysis. Due to interfacial activation of the lipase in the presence of Triton X-100, a seven-fold increase of hydrolys...

The purpose of this research is to study the effect methods preliminary preparation thermally activated clay, which a pozzolanic component in water-resistant composite gypsum binders, as well mechanochemical activation joint grinding clay with addition plasticizer on activity and change required number composition binders. It was found that amount gypsum-cement-pozzolan when ground specific sur...

Concrete is the second-most-used substance after water, and more than six billion tons of cement are produced each year. As part current investigation for new innovations in concrete as well to decrease aggregate waste, an experimental assessment on self-compacting with varied percentages coarse recycled was conducted. The major objective investigate use effects next generation concretes. envir...

Antioxidant biocomposites have been successfully developed from cellulose acetate, eco-friendly triethyl citrate plasticizer and onion extract as a source of natural antioxidants. First, an onion extraction process was optimized to obtain the extract with highest antioxidant power. Extracts under absolute ethanol and ethanol 85% were the extracts with the highest antioxidant activity, which wer...

The subject of this study is the synthesis glycolysates from recycled poly (ethylene terephthalate) (PET) by depolymerization using diethylene glycol (DEG) in presence catalyst FASCAT 4100. resulting glycolysate was then treated with maleic anhydride and finally 2-octanol to obtain a 2-EtHex/MA/DEG/PET/EG/MA/2-EtHex plasticizer. characterization obtained plasticizer performed infrared spectrosc...

The most common and reliable material without which modern construction is indispensable concrete. development of production pushing for new solutions to improve the quality concrete mix demanded significant indicators a mixture are compressive strength mobility mixture. Every year, volume research on nanomaterials as modifying components significantly increasing, results indicate prospects the...
