Based on theoretical studies, the authors of this paper propose use cosmetic organosilicon polymers (commonly called silicones) for extraction a complex biologically active substances contained in vegetable raw materials. It is important to note that biological molecules do not interact with organosilicones and, therefore, their properties are altered after extraction. In work, we investigate e...

This paper discusses the state of art in application self-healing silicone-based materials for outdoor high-voltage insulation. Both dynamic behavior dimethyl side groups silicone rubber and diffusion a bulk siloxane to maintain low surface energy are respectively reported as intrinsic mechanisms responsible rubber. Localization, temporality, mobility, type synthesis aspects defining efficiency...

Background: There are several elastic impression materials available for dental use. The present study evaluated accuracy of different used in impressions fixed partial dentures.Materials & Methods: A master model partially edentulous mandibular left hemi-arch segment was used. Custom trays were prepared with auto-polymerizing acrylic resin and taken using alginate elastomeric stone casts forme...
