Item type:Publication, Characterization of Nanoscaled TiO2 Produced by Simplified Sol–Gel Method Using Organometallic Precursor(ASME International, 2015-04-01); ; Gentile, Gennaro<jats:p>This work is concerned with development of sol–gel method for preparation of nanoscaled TiO2 using organometallic precursor—titanium tetraisopropoxide (TTIP) and determination of the present crystalline phases depending on the temperature of further thermal treatment. The characteristic processes and transformations during the thermal treatment were determined by means of thermal gravimetric analysis and/or differential thermal analysis (TGA/DTA) method. The crystalline structure and size of the TiO2 crystallites were analyzed by means of Raman spectroscopy and X-ray powder diffraction (XRPD) method. At 250 °C, cryptocrystalline structure was detected, where amorphous TiO2 is accompanied with crystalline anatase. The anatase crystallite phase is stable up to 650 °C, whereas at higher temperature rutile transformation begins. It was observed that at 800 °C, almost the whole TiO2 is transformed to rutile phase. According to XRPD analysis, the increase of the temperature influences on the increase of the size of the crystalline particles ranging from 6 nm at 250 °C to less than 100 nm at 800 °C. The size and shape of the TiO2 crystalline particles were observed by transmission electron microscopy (TEM). The shape of the studied samples changes from nanospheres (250, 380, and 550 °C) to nanorods (650 and 800 °C). Morphology of the formed TiO2 aggregates was observed by scanning electron microscopy (SEM).</jats:p> - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Hydrofluoric Acid: Burns and Systemic Toxicity, Protective Measures, Immediate and Hospital Medical Treatment(ID Design 2012/DOOEL Skopje, 2018-11-25); Bajraktarova-Misevska, CvetankaHydrofluoric acid is a commonly used chemical in many industrial branches, but it can also be found as an ingredient in household products such as cleaning agents. Possessing high corrosive potential, HF acid causes burns and tissue necrosis, while when absorbed and distributed through the bloodstream, its extremely high toxic potential is expressed. Acute symptoms are often followed by pain, particularly in the case of skin burns, which intensiveness does not often correlate with the expressiveness of the clinical findings. Even exposure to low-concentrated solutions or gasses, or low-doses of high-concentrated acid, may provoke delayed systemic disorder which may eventually have a lethal outcome. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, From optimization of synbiotic microparticles prepared by spray-drying to development of new functional carrot juice(National Library of Serbia, 2014); ; Hadjieva, Jasmina<jats:p>Lactobacillus casei loaded chitosan-Ca-alginate microparticles enriched with the prebiotic fructooligosaccharide were prepared using spray-drying method associated with the polymers complexation and cross-linking with calcium. The concentrations of the formulation factors of alginate, chitosan and CaCl2 were optimized using 23 full factorial design. Experiments showed that microparticles with favorable physicochemical properties and high probiotic viability during preparation and storage could be obtained when 40 mg/g sodium alginate, 5 mg/g chitosan and 50 mg/g CaCl2 is used. Stability of L. casei during microencapsulation was identified by FTIR spectroscopy. The viability of the probiotic in the optimal formulation of synbiotic microparticles remained above the therapeutic minimum during incubation of 24 hours in simulated gastrointestinal conditions (7.67?0.4 log cfu/g) as well as after 3 months of cold storage (8.1?0.6 log cfu/g). High viability of L. casei was maintained during 6 weeks of cold storage when carrot juice was enriched with encapsulated cells. The effective preservation of L. casei into synbiotic microparticles provided production of new non-dairy functional food as an alternative of the population who is at risk of lactose intolerance.</jats:p> - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Effect of prebiotic content on functional and physicochemical properties of Lactobacillus casei loaded chitosan-Ca-alginate microparticles(Macedonian Pharmaceutical Association, 2012-10); ; ; <jats:p>This study aims to evaluate the influence of different concentrations of fructooligosaccharide (FOS) as prebiotic on functional and physicochemical properties of Lactobacillus casei loaded chitosan-Ca-alginate microparticles prepared by spray-drying method, after preparation and 6-month storage at 4 °C. Prebiotic compound positively influenced the viability of L. casei during preparation of the microparticles and in storage conditions, while no significant difference of the probiotic viability was observed when different concentrations of FOS in a range of 1.5 - 5% w/w were applied. Having in regard that non-significant improvement in the functional and physicochemical properties of the microparticles with increased content of the FOS was observed, the concentration of 1.5% w/w was recommended as an optimal for preparation of synbiotic loaded microparticles.</jats:p> - Some of the metrics are blocked by yourconsent settings
