The use of bone implants and prostheses has contributed to a revolution in modern medicine; however, the beginning, not much was asked from implant prosthetic materials per se. Therefore, next game-changer orthopedic research will come new material designs which for instance can aid prevention implant-associated infections. Here, we describe development sol-gel coating technique that deliver an efficient antimicrobial surface on implants. Gentamicin stocked novel nanocomposite xerogel made...
Dendritic polymers are artificial compounds with a unique, repeatedly branched structure inspired by the respective patterns, encountered in trees. They recognized as fourth major macromolecular architectural class next to linear, cross linked and polymers. Regarding formation of liquid crystalline phases, they follow same rules all other categories. Suitable chemical functionalization induces segregation. Secondary interactions, form hydrogen bonds particular, also play crucial role...
Silica-organic matrix-silver, nano-catalysts, were synthesized employing four different hyperbranched poly(ethylene imines) (MW 2000 to 750,000) reduce Ag+ metal nanoparticles and the formation of SiO2 shells. The latter is performed at pH 7,5 three regulating agents Hepes, Trizma, Phosphate Salts. Characterization resulting materials with spectroscopy (FTIR), thermogravimetry (TG), scanning electron microscopy (SEM), ζ-potential reported. Kinetic studies standard reactions, 4-nitrophenol...
A novel hybrid, water-based, sol-gel method was developed for the synthesis of functionalized silica with advanced adsorptive capacities towards heavy metal ions. The study employs hyperbranched poly(ethylene imine) (HBPEI) as a reactive template silica. reaction followed by FTIR, whereas material evaluated in terms its microstructure and properties. results revealed very potent adsorbent that can remove ions (namely, Pb, Cu, Zn) from water fast efficient way. Greater selectivity observed...
The effect of secondary hydrogen-bonding interactions on the crystalline and liquid phases quaternary ammonium salts functionalised with a carboxylic group attached at polar head through decyl spacer homologous series N-alkyl-N-carboxydecyl-N,N-dimethylammonium bromides was investigated by polarising optical microscopy, differential scanning calorimetry X-ray diffraction. low-temperature crystal were found to have lamellar structure in which bromide groups are arranged within layers two...
In recent years, research has revolved around materials with superior functionality. Despite the encouraging results, their commercial use is limited due to high production costs. The major drawback of nanomaterials tendency form aggregates that limit activity. order overcome barriers, synthesis advanced, composite proposed. These must exhibit mechanical strength, adhesion between substrate and coating, enhanced properties when compared or coating. present work, expanded perlite substrates...
Hip joint surgeries, including total hip replacement or resurfacing, have increased tremendously in the last decades. Number of patients all ages, replace their hip, due to severe injuries trauma problems, so as a better life. According these factors, new material and processes implants manufacturing are imported medicine, through research programs, every year. In scope one that has do with ceramic coatings on metallic resurfacing implants, 3axis simulator was designed manufactured...
In the current study, synthesis of hydroxyapatite-ceria (HAP-CeO2) scaffolds is attempted through a bioinspired chemical approach. The utilized colloidal CeO2 suspension presents antifungal activity against Aspergillus flavus and fumigatus species at concentrations higher than 86.1 ppm. Three different series composite HAP-CeO2 suspensions are produced, which differentiated based on precursor to added by whether this addition takes place before or after formation hydroxyapatite phase. Each...
