Preformulation studies regarding a physico-chemical evaluation of memantine, a non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist, are presented in this work. This characterization of memantine is pre-required for the formulation of a parenteral solution. The water solubility, the thermal behavior and the chemical stability in aqueous solution, depending on the pH, temperature, UV ...

Magnetic nanocomposites are an important class of advanced functional materials on the basis of a magnetic material and a matrix. To achieve unique mechanical, physical, chemical, and biomedical properties, one must be able to tailor only the surface structures of a nanoparticle. This requires the deposition of ultrathin and uniform films using the possibility offered by cold-plasma polymerisat...

Geographical and botanical origin of honeys can be characterized on the basis physico-chemical composition, sensory properties melissopalynological analysis. No comprehensive description characteristics Czech honey has been published so far. This study provides insights that are important for correct classification. The analysed 317 samples authentic from randomly selected localities. Due to di...

Biomagnetic nano and microparticles platforms have attracted considerable interest in the field of biological sensors due to their interesting physico-chemical properties, high specific surface area, good mechanical stability and opportunities for generating magneto-switchable devices. This review discusses recent advances in the development and characterization of active biomagnetic nanoassemb...

Hydrothermal features in Portugal have been used since ancient times for therapeutic purposes that are mainly distributed in north and central region, being Beira Interior, located in central region, is characterized by eight spas. As for Portuguese thermo-mineral waters there are scarce studies about the characterization of its relation with the beneficial effects on human health. In last deca...

Preparation of silver immobilized TiO2-Hectorite and its application in phenol photooxidation and Eschericia coli bacteria desinfection has been conducted. Material was obtained by two steps of synthesis: preparation of TiO2-Hectorite and silver immobilization into TiO2-Hectorite. Physico-chemical characterization to the prepared material compared to raw hectorite was conducted by X-ray Diffrac...
