    Fundamental and Practical Aspects of Tribology
    (CRC Press, 2024) Berman, Diana; Rosenkranz, Andreas; Marian, Max
    © 2025 Diana Berman, Andreas Rosenkranz, and Max Marian.Fundamental and Practical Aspects of Tribology introduces the rudiments of engineering surfaces and teaches the basic phenomena of interacting surfaces in relative motion, major modes of friction and wear, and theories of contact evolution and lubrication. Fundamental topics include friction, wear, and lubrication; surface properties and surface topography; friction of surfaces in contact; wear and surface failures; biotribology; boundary lubrication; fluid properties; hydrodynamic lubrication; bearing selection; and introductory micro- and nanotribology. This book also considers the relationship between nano- and macrotribology, rolling contacts, tribological problems in magnetic recording and electrical contacts, and monitoring and diagnosis of friction and wear. • Offers a comprehensive review of the fundamentals, providing basic information for scientists and engineers just being introduced to the tribology field • Teaches tribological methods of measurements and characterization • Includes examples of real-life tribological problems and case studies of engineering problems and solutions • Gives an overview of current advancements in the field • Features end-of-chapter problems, solutions to exercises, and accompanying video content for reinforcement of material This textbook is written for students taking courses in tribology and lubrication, as well as surface engineering. It will also appeal to scientists and engineers who are new to tribology. The text also offers sample laboratory demonstrations available to qualifying adopting professors.

    Layered 2D Nanomaterials to Tailor Friction and Wear in Machine Elements—A Review
    (2022) Marian, Max; Berman, Diana; Rota, Alberto; Jackson, Robert L.; Rosenkranz, Andreas
    Recent advances in 2D nanomaterials, such as graphene, transition metal dichalcogenides, boron nitride, MXenes, allow not only to discover several new nanoscale phenomena but also to address the scientific and industrial challenges associated with the design of systems with desired physical properties. One of the great challenges for mechanical systems is associated with addressing friction and wear problems in machine elements. In this review, the beneficial properties of layered 2D materials that enable the control of their tribological behavior and make them excellent candidates for efficient friction and wear reduction in dry-running and boundary lubricated machine components are summarized. The recent studies highlighting the successful implementation of 2D structures when used as solid lubricant coatings or reinforcement phases in composites for various machine components including sliding and rolling bearings, gears, and seals are overviewed. The examples presented in the studies demonstrate the great potential for 2D materials to address the energy-saving needs by friction and wear reduction.

    Roadmap for 2D materials in biotribological/biomedical applications – A review
    (2022) Marian, Max; Berman, Diana; Nečas, David; Emami, Nazanin; Ruggiero, Alessandro; Rosenkranz, Andreas
    The human body involves a large number of systems subjected to contact stresses and thus experiencing wear and degradation. The limited efficacy of existing solutions constantly puts a significant financial burden on the healthcare system, more importantly, patients are suffering due to the complications following a partial or total system failure. More effective strategies are highly dependent on the availability of advanced functional materials demonstrating excellent tribological response and good biocompatibility. In this article, we review the recent progress in implementing two-dimensional (2D) materials into bio-applications involving tribological contacts. We further summarize the current challenges for future progress in the field.
