Friction on biological-like micro-structured surfaces has been investigated. Using a bio-replication technique, complex surface morphologies found in plant leaves were transferred onto viscoelastic substrates. A nano-indenter was modified, permitting in-situ real contact junctions visualisation. Effects of applied normal load and sliding speed the friction response evaluated. All four demonstra...
The concept of soft sets, introduced by Molodtsov [20] is a mathematicaltool for dealing with uncertainties, that is free from the difficultiesthat have troubled the traditional theoretical approaches. In this paper, weapply the notion of the soft sets of Molodtsov to the theory of Hilbert algebras.The notion of soft Hilbert (abysmal and deductive) algebras, soft subalgebras,soft abysms and sof...
Many dental implants fail due to the infection and inflammation that walk hand in hand with poor healing and soft tissue integration. Titanium surfaces were nanocoated with quercitrin, a natural flavonoid, with the aim to improve soft tissue integration and increase dental implants success. Streptococcus mutans attachment and biofilm formation was analysed. Then, the anti-inflammatory propertie...
Deposition of wax on a cold surface is a serious problem in oil production. Progress in developing more effective wax inhibitors has been impeded by the lack of an established mechanism connecting the molecular structure to inhibitor efficiency. Some comb-like polymers having long alkyl side chains are known to decrease the rate of wax formation. Among several possible mechanisms, we investigat...
Abstract Interaction of foams with porous materials is frequently observed in industry and nature. An example the interaction foam a cleaning product sponge, which has been investigated previously Johnson et al., Colloids Surfaces A , 2019, 579, June, p. 123569 commercial dishwashing solution using compression device sponge saturated surfactant solution. The purpose this study to investigate sa...
