Abstract Today gold is used as contact material on electric contacts for low current applications. Gold, however, has low wear resistance, is expensive and environmentally stressful to produce. An alternative contact material to gold is nano composite Ti-Si-C-Ag deposited with DC-magnetron sputtering. Nano composite Ti-Si-C-Ag has so far been deposited by a compound Ti-Si-C sputter target with ...
A method has been proposed for developing structure-property relationships of nano-structured materials. This method serves as a link between computational chemistry and solid mechanics by substituting discrete molecular structures with equivalent-continuum models. It has been shown that this substitution may be accomplished by equating the molecular potential energy of a nano-structured materi...
Control contact systems represent controlled (or open) irreversible processes which allow to represent simultaneously the energy conservation and the irreversible creation of entropy. Such systems systematically arise in models established in Chemical Engineering. The differential-geometric of these systems is a contact form in the same manner as the symplectic 2-form is associated to Hamiltoni...
Atomic force microscopy (AFM) is capable of solid surface characterization at the microscopic and submicroscopic scales. It can also be used for the determination of surface tension of solids (gamma) from pull-off force (F) measurements, followed by analysis of the measured F values using contact mechanics theoretical models. Although a majority of the literature gamma results was obtained usin...
Superior first-cycle Coulomb efficiency (above 80%) is displayed by filter paper-derived micro-nano structure hard carbon, and it delivers a high reversible capacity of 286 mAh g-1 after 100 cycles as the anode for Na-ion battery at 20 mA g-1. These advantageous performance characteristics are attributed to the unique micro-nano structure, which reduced the first irreversible capacity loss by l...

Orthopaedic and dental implants have become a staple of the medical industry and with an ageing population and growing culture for active lifestyles, this trend is forecast to continue. In accordance with the increased demand for implants, failure rates, particularly those caused by bacterial infection, need to be reduced. The past two decades have led to developments in antibiotics and antibac...
