Abstract In rural areas of Romania and other developing countries wounds and dermal affections represent one of the five most common reasons for people seeking medical care. The use of traditional medicines to treat many of these conditions has received little research or policy attention. The present work addresses the discovery of non-toxic treatments for dermal affections, and aims to prepare – based an environmentally friendly technology, and characterize hydrogels based on gelatin...

This research offers a novel approach for potato wastewater (PW) bioconversion to alcohol by microwaves gelatinization, liquefaction and simultaneous saccharification and fermentation (SSF). Concentrated PW from potato processing to obtain fries was treated by gelatinization, enzymatic hydrolysis through liquefaction and saccharification, and fermentation; a mini-bioreactor was used, with low oxygen, temperature, pH and mixing control. The yeast Saccharomyces cerevisiae and a commercial mix of l...

Novel systems based on modified azo-polysiloxanes and gelatin with potential biological applications were prepared and characterized. Simultaneous rheological and UV irradiation studies allowed evidencing structural modification inside the gelatin matrix. For all analyzed samples a shift in the temperature corresponding to the physical network destructuration, from 30˚C (corresponding to gelatin) to 40˚C (for the composite) was noticed. The experimental results proved the existence of ...

The main goal of this work was to develop a cheap and easy method for the synthesis of the porous metallosilicate macrospheres. Zirconium silicate macrospheres with diameters in the range 1.5 – 1.6 mm were obtained by the spray gelling technique, using the multi templating method. Tetraethyl orthosilicate was used as silica source. The chitosan played a dual role (pore and shape generating agent), while other inexpensive and easily accessible biomaterials including yeast, sugar and gelatin...
