Pharmaceutical grade bentonite, containing a high amount of montmorillonite, enriched with zinc (Zn) or copper (Cu) (ZnBent and CuBent, respectively) was used as the main component for creation formulations cutaneous use tested their antimicrobial capacity. Bentonite (Bent) added phenoxyethanol (PH) preservative unmodified bentonite were control groups. The mineralogical composition, structural state, physical chemical properties, before after modification samples, characterized utilizing...
The main objective of this work was to synthesize composites polyurethane (PU) with organoclays (OC) exhibiting antimicrobial properties. Layered silicate (saponite) modified octadecyltrimethylammonium cations (ODTMA) and functionalized phloxine B (PhB) used as a filler in the composites. A unique property composite materials is increased concentration modifier particles on surface membranes. Materials different compositions were tested investigated using physico-chemical methods, such...
Six pharmaceutical pastes were prepared using chemically modified kaolin and talc powders. Tests conducted to determine their structural chemical characteristics as well antimicrobial protection, thus rendering them suitable for cosmetic uses. Kaolin treated via the cation exchange method load clay particles with copper zinc ions, two cations known properties. Mineralogical analyses by X-ray diffraction (XRD) before after modification, confirming mineralogical purity of samples. Scanning...
The development of bioactive ceramics still poses challenges in finding a good compromise between bioactivity and mechanical robustness. Moreover, facile, low-cost energy-saving synthesis technique is needed. This study concerns the material by growing Na-Ca-Mg-Si-based ceramic matrix produced using alkali-activation method on silicon nitride (Si
Poly(2-oxazoline)s (POxs) are nonionic polymers suitable for different bioapplications. Composites of montmorillonite (Mnt) and poly(2-methyl-2-oxazoline) (PMeOx), poly(2-ethyl-2-oxazoline) (PEtOx), poly(2-propyl-2-oxazoline) (PPrOx) were prepared the first time, effect polymer loadings side chain length on adsorption structural characteristics was examined. Adsorption isotherms revealed a sharp increase in at low loadings. When surface Mnt saturated with POxs, plateau not changing loading...
Polymer/layered silicate composites have gained huge attention in terms of research and industrial applications. Traditional nanocomposites contain particles regularly dispersed a polymer matrix. In this work, strategy for the formation composite thin film on surface polycaprolactone (PCL) matrix was developed. addition to polymer, layer composed saponite (Sap) modified with alkylammonium cations functionalized methylene blue. The connection between phases Sap achieved by fusing chains...
NaSICON fast-ionic conductors have been largely considered as a viable solution for the development of energy storage units. Chemical doping is popular technique to improve their electrochemical performance, and widely accepted criterion an aliovalent substitution, increase cationic density, and/or isovalent susbtituion with larger species, enlarge bottleneck, speculated LATP series. However, this study demonstrates through impedance spectroscopy that ionic conductivity Na3Fe2(PO4)3...
