Hydrogel surfaces are of great interest in applications ranging from cell scaffolds and transdermal drug-delivery patches to catheter coatings and contact lenses. In this work, we propose a method to control the surface structure of hydrogels, thereby tailoring their frictional properties. The method is based on oxygen inhibition of the free-radica...

We synthesized two resorcin[4]arene scaffolds with four phosphate binding groups. The superior binding affinity to nanocrystal surfaces is demonstrated using solution NMR spectroscopy and exceeds that of single phosphonates.

The present study investigated a hybrid electrical discharge machining (h-EDM) process for producing functionally graded titanium surface. Herein, a stream of hydroxyapatite/titanium oxide abrasive slurry jet has been supplied, through a specially designed tool, to the ionized zone created by the EDM process, and the abrasive particles were finally...

Iron oxide-silica nanocomposites were prepared by sol-gel method using ammonia (NH3), acetic acid (CH3COOH) and hydrochloric acid (HCl) catalysts to generate different pH values for the reaction conditions. As starting precursors, for the silica, respectively, for the iron oxide, tetraethylorthosilicate (TEOS) and iron-III-acetylacetonate were used...

Polarization of electromagnetic waves plays an extremely important role in interaction of radiation with matter. In particular, interaction of polarized waves with ordered matter strongly depends on orientation and symmetry of vibrations of chemical bonds in crystals. In quantum technologies, the polarization of photons is considered as a “degree o...
The ion exchange processes and phase formation were studied by varying the properties of 1D barium titanate nanostructures. Temperature-, timeand alkalinity-dependent experiments were performed to study the BaTiO3 formation mechanism involving the generation of chemical sites which induced in situ transformation and dissolution-precipitation reacti...
The surface texturing of ceramics is generally performed through acid-based etching and machining; however, laser texturing may be considered as a more precise, reproducible and eco-friendly process. Furthermore, laser ablation may be used to produce complex patterns on ceramic surfaces, thus offering new surface engineering opportunities. The stud...
