The adhesion of Acidithiobacillus ferrooxidans bacterial cells have been assessed by following the thermodynamic and extended DLVO theoretical approaches. Surface potential, interfacial tension and contact angle parameters that are necessary for the calculation of free energy of adhesion have been determined experimentally. The Hamaker constant involved in the Lifshitz-van der Waals interaction...

Based on the size-dependent cohesive energy formula for two-dimensional materials, we investigate the gap openings in graphene layers regarding distinct interfacial interaction from substrates. Depending on the interfacial physicochemical nature, the gap is opened weakly induced by the van der Waals interaction but readily by the chemical bonding. Relative to the former, in essence, the distinc...

Studies of atomistic mechanisms, energetics and dynamics of surface and interfacial processes using computer-based molecular dynamics simulations employing realistic interaction potentials, open new avenues in investigations of basic and technological problems. Recent results of such studies are discussed for. surface processing via laser irradiation, superheating, melting, and annealing; stabi...

This work is concerned with the diffraction and scattering of plane electro-acoustic waves by an interfacial crack between two dissimilar piezoelectric half-spaces. An exact solution is obtained for the full scattering field around the tip of the interfacial crack that is loaded with both acoustic SH and electric incident waves. First, it has been found that the interfacial crack is not complet...

The electrodes of semiconductor gas sensors are important in characterizing sensors based on their sensitivity, selectivity, reversibility, response time, and long-term stability. The types and materials of electrodes used for semiconductor gas sensors are analyzed. In addition, the effect of interfacial zones and surface states of electrode-semiconductor interfaces on their characteristics is ...

Neuromorphic computing (NC) has been gaining attention as a potential candidate for artificial intelligence. The building blocks NC are neurons and synapses. Research studies have indicated that domain wall (DW) devices one of the most energy-efficient contenders realizing NC. Moreover, synaptic functions can be achieved by obtaining multi-resistance states in DW devices. However, with no pinni...
