Nikolay Goloshchapov, PhD, has more than 30 years of experience in the fields of physics, mechanical engineering, tribology, and materials science, particularly physics and mechanics of materials and polymers and elastomers. He is currently an independent private scientific consultant at NNG—Engineering & Physics Science Consultancy, London, UK. He is a specialist in applied physics and math-mechanics, tribology, and fatigue life (the wear out and erosion of materials under collision of solids, particularly in optimizing the basic dynamic and mechanical qualities of visco-elastic materials and elastomers [rubbers] for their exploitation in gas jet or flow abrasive solids and substances in different temperatures and velocities of loading and impact). He has acted as a reviewer of articles for international journals on such topics as scientific instruments and nonlinear dynamics.
