Ultrathin nanocomposite films were prepared on solid supports via adsorption of organic and inorganic molecules from solution. Coordination geometry for transition metal ions was preserved by embedding metal ligands into titanium oxide gel films, and porous titanium oxide films were prepared by selective removal of organic components from polymer/metal oxide composite films using oxygen plasma ...

Motivation It has been recognized by many within the energetic materials community that the use of nano-sized energetic particles can lead to substantial increases in overall performance and safety of energetic materials. Nano-sized energetic particles offer the potential of high heat release rates, increased combustion efficiencies, tailored burning rates, and reduced sensitivity. In order to ...

Ceramic dental materials have been considered as alternatives to metals for dental implants application. In this respect, zirconia tetragonal stabilized with %3 yttrium, is of great importance among the ceramic materials for endosseous dental implant application. Because of its good mechanical properties and color similar to tooth. The aim and novelty of this study was to design and prepare Y-T...

Bottom-up approaches have gained significant attention recently for the creation of nano-sized, ordered functional structures and materials. Stepwise coordination techniques, in which ligand molecules and metal sources are reacted alternatively, offer several advantages. Coordination bonds are stable, reversible, and self-assembling, and the resultant metal complex motifs may contain functional...

Polymer conjugates are nano-sized, multi-component constructs already in the clinic as anticancer compounds, both as single agents or as elements of combinations. They have the potential to improve pharmacological therapy of a variety of solid tumors. Polymer-drug conjugation promotes passive tumor targeting by the enhanced permeability and retention (EPR) effect and allows for lysosomotropic d...

Biodegradable polymers have been widely used as scaffolding materials to regenerate new tissues. To mimic natural extracellular matrix architecture, a novel highly porous structure, which is a three-dimensional interconnected fibrous network with a fiber diameter ranging from 50 to 500 nm, has been created from biodegradable aliphatic polyesters in this work. A porosity as high as 98.5% has bee...
