The design of the facade is of great importance in every building, because it is the first part of the building to be exposed, and it will be very effective in creating the initial mentality of someone who enters the building. The use of special designs and colors in interior and exterior decoration is welcomed by manufacturers and buyers. One of the more recent designs is the use of golden elements made of stainless steel with TiN golden coatings. These ceramic coatings, in addition to the strength and mechanical properties, provide good corrosion resistance. There are different methods to apply TiN coatings on substrates. Arc-PVD is a kind of physical vapor deposition technique in which an electric arc is used to vaporize material from a cathode target. The vaporized material then condenses on a substrate and forms a thin film.
Interior and exterior facade of buildings, elevators and other decorative applications.
Creating nanostructured coatings on the substrate will improve the abrasion, erosion and corrosion properties of the substrate.

Proper air filtration is critical to the overall performance and reliability of gas turbines. The latest evolution in the filtration industry is the use of nanotechnology in this field. With this technique, the surface of large cellulosic or synthetic textiles (usually 10 to 30 micrometers in diameter) is covered with a layer of ultra-fine textiles (typically 50 to 400 nanometers in diameter). There are two different methods for separating particles in the filter paper structure.
In-depth filtration, in which particles are separated in different layers of paper according to their size; and surface filtration, in which all particles are separated on the surface of paper. In Behran Co. before pleating process, the filter paper is covered with a layer of Polyamide textiles with diameter of less than 100 nanometer by using electrospinning process.
Ceramic tiles due to having excellent chemical stability, as well as good appearance are widely used in different places such as hospitals and buildings. normally, the microorganisms reproduce easily on the ceramic tile surface, especially in wet environment. The silver-titanium nanocomposite particles have an antibacterial effect which can kill more than 650 different types of bacteria and they are not harmful to the environment and the human body. The silver-titanium nanocomposite particles along with silver ions in the ceramic glaze, penetrate the cell walls of bacteria and microorganisms and prevent their growth and reproduction. These nanoparticles can be mixed with ceramic glaze as an additive.
Catalytic reforming is a major conversion process in petroleum refinery which converts low octane naphthas into higher octane reformate products for gasoline blending and aromatic rich reformate for aromatic production. To perform the process correctly and efficiently, as well as to prevent coke making, the process structure and catalyst must be selected optimally. The efficient structure of the reforming reactors is continues catalytic reforming (CCR). In this process the catalyst is key component. The γ–alumina based catalyst is amongst the catalysts that has a long history in catalytic reforming. In naphtha reforming, γ–alumina is responsible for acidic interactions; moreover, the dehydrogenation reactions are performed by some metals which are impregnated to the catalyst. Therefore, alumina-based catalyst is a very suitable candidate for catalytic reforming.
Concrete is unique in construction and it is only an exclusive product for trading; so it involves a significant share of research and development, and income in the industry to itself. Concrete, a multi-phase, complex and nanostructured material, is a composite structure mainly composed of cement and water. Nanoscience and nanoengineering of concrete are phrases which describe two essential approaches regarding the application of nanotechnology in concrete. Up to now, concrete has been primarily known as a structural material. Nanotechnology is capable of making a multi-functional material from concrete. Concrete can be nanoengineered by incorporating nanoscale building blocks, nanoparticles, nanotubes, etc.
