CONTACT MECHANICS AND FRICTION: PHYSICAL PRINCIPLES AND APPLICATIONS

Review of "Contact Mechanics and Friction: Physical Principles and Applications" by Valentin L. Popov

The book “Contact Mechanics and Friction: Physical Principles and Applications” is written by a theoretical physicist but from the point of view of an engineer. It covers an amazingly broad spectrum of topics ranging from atomic scale friction, continuum and structural mechanics, materials science, lubrication, adhesion, capillarity and system dynamics. It provides conceptual and computational ...

Quantum Mechanics: Fundamental Principles and Applications

Small interfering RNA; principles, applications and challenges--

Gene silencing using RNAi (RNA interference), has recently been used as a successful laboratory technique in determining the function and control of gene expression and provides a wide range of applications in molecular biology and gene therapy. RNAi is a method of suppressing gene expression. In this direction, a single-stranded RNA molecule of about 21–23 nucleotides, called siRNA (small inte...

Canonical dual approach for contact mechanics problems with friction

This paper presents an application of canonical duality theory to the solution of contact problems with Coulomb friction. The contact problem is formulated as a quasi-variational inequality whose solution is found by solving its Karush– Kuhn–Tucker system of equations. The complementarity conditions are reformulated by using the Fischer–Burmeister complementarity function, obtaining a non-conve...

The Principles and Recent Applications of Bioelectrocatalysis

Bioelectrocatalysis is a phenomenon concerned with biological catalysts, which accelerate the electrochemical reactions. Bioelectrocatalysis has been widely explored by the research community in various directions. Enzymes can catalyze different chemical reactions in living organisms by enzymes as the most important biological catalysts. These enzymatic biocatalysts are commercially available a...
