The inventions in nanotechnologies as practical solutions. Part II

A brief review of patents is given. The research performed by scientists, engineers and specialists in the area of nanotechnologies and nanomaterials result in increased efficiency of construction, housing sector and adjacent fields of economy. For example, invention «Elastic conductive film on the basis of silver nanoparticles», according to experts, is of great interest for science and industry. This new type of electronics potentially can be applied in many fields, such as elastic sensor skin for robot devices, portable electronics for functional clothes, elastic sensors and flexible electronic displays. Elasticity of materials is highly needed in electronic devices that contact the human body or curved surfaces. Elastic conductive film contains many annealed nanoparticles of conductive metal, in particular silver, applied on substrate. Adhesion of silver film is of great quality: when abrasion test was finished, there were no defects or there were slight defects. The specialists can also be interested in the following inventions in the area of nanotechnologies: a method to introduce single-wall and/or two-wall and/or multi-wall carbon nanotubes in composition of adhesive additives for asphalt coating and application of single-wall and/or two-wall and/or multi-wall carbon nanotubes in composition of adhesive additives; welding wire with nanocomposite coating for welding of high-tensile steel; A method to produce nanocomposite material based on aluminium; sewage treatment system with nanomodified natural sorbents et al

Inventions of Scientists, Engineers and Specialists from Different Countries in the Area of Nanotechnologies. Part VI

Introduction. Advanced technologies impress people\u27s imagination demonstrating the latest achievements (materials, methods, systems, technologies, devices etc.) that dramatically change the world. This, first of all, concerns nanotechnological inventions designed by scientists, engineers and specialists from different countries. Main part. The article provides an abstract overview of inventions of scientists, engineers and specialists from different countries: Russia, USA, China, Kazakhstan, Sweden. The results of the creative activity of scientists, engineers and specialists, including inventions in the field of nanotechnology and nanomaterials allow, when introduced to industry, achieving a significant effect in construction, housing and communal services, and related sectors of the economy. For example, the invention \u27A method to obtain polymer-composite material and a composite reinforcement \u3e\u3e relates to construction materials and is designed to reinforce building structures, that allows obtaining strengthened stressed composite reinforcement with improved physical-mechanical characteristics, increased resistance to aggressive environments. A method to obtain polymer-composite material is a multi-stage production of colloid solution on the basis of epoxy resin with addition of carbon nanotubes and applying heat and ultrasound impact. Introduction of modifiers (fillers) in polymer matrix in a certain ratio and fillers orientation make it possible to create a polymer strengthened for mechanical loads and with increased resistance to aggressive media (acid-resistance and alkali-resistance). The following inventions in the field of nanotechnology can also be interesting for specialists: a method to obtain biocide suspension applied on wallpaper and wall finishings, a method of aerosol spraying of nanoparticles in constant electric field, a method to obtain amorphous nanostructured diamond-like coating, a polymer composite heat-conducting paste with nanofiber modifier, a plant to provide controlled electroimpulse obtaining of nanoparticles of current conducting materials, etc. Conclusion. One of the most challenging tasks the economy of every country faces is to increase industrial competitiveness through technological upgrade. From the side of the state and companies the principal object to control in this process are the people and enterprises dealing with introduction of inventions and new technologies
