A coating system integrating three distinct chemistries was developed to protect materials used in monuments and construction. Initial curing is achieved using a UV-initiated thiol-ene reaction form non-impressionable/non-sticky surface. Second, amine/epoxy reactions firm surface adhesion give mechanical strength through consolidation. Third, alkoxysilane sol-gel integrates the siloxane network...

Sol-gel technology is increasingly being used in coatings for corrosion protection and adhesion improvement. So far, the self-healing concept in sol-gel coatings has only been approached from extrinsic healing perspective (i.e. use of nano and micro carriers of corrosion inhibitors) [1]. Despite the benefits of this approach, the damaged area remains open to ambient environment. The implementat...

Oil and Gas pipelines are protected by various types of external coatings in conjunction with CP systems. Polyethylene is commonly used as the top coat in two or three layer systems. The existing two layer system found in the North American and Australian markets uses an adhesive that is mastic-based. It provides excellent corrosion resistant properties and has relatively low shear resistance i...

This study characterized the electrical and optical properties of single-junction GaAs solar cells coated with antireflective layers of silicon dioxide (SiO₂), indium tin oxide (ITO), and a hybrid layer of SiO₂/ITO applied using Radio frequency (RF) sputtering. The conductivity and transparency of the ITO film were characterized prior to application on GaAs cells. Reverse saturation-current and...

Bone tissue engineering has emerged as a promising alternative approach in the treatment of bone injuries and defects arising from malformation, osteoporosis, and tumours. In this approach, a temporary scaffold possessing mechanical properties resembling those of natural bone is needed to serve as a substrate enhancing cell adhesion and growth, and a physical support to guide the formation of t...

Fabric flammability is a surface-confined phenomenon: in fact, the fabric surface represents the most critical region, through which the mass and heat transfers, responsible for fueling the flame, are controlled and exchanged with the surroundings. More specifically, the heat the fabric surface is exposed to is transferred to the bulk, from which volatile products of thermal degradation diffuse...

Possibilities of the development new anti-erosion coatings for wind turbine blade surface protection on basis nanoengineered polymers are explored. Coatings with graphene and hybrid nanoreinforcements tested their performance, using single point impact fatigue testing (SPIFT) methodology. It is demonstrated that (graphene/silica) reinforced polymer can provide better erosion lifetimes up to 13 ...
