Cocrystals, solid mixtures of different molecules on molecular scale, are supposed to be tailor made materials with improved employability compared to their pristine individual components in domains such as medicine and explosives. In medicine, cocrystals are obtained by crystallization of active pharmaceutical ingredients with precisely chosen coformers to design medicaments that demonstrate e...

Current induced spin wave excitations in spin transfer torque nano-contacts are known as a promising way to generate exchange-dominated spin waves at the nano-scale. It has been shown that when these systems are magnetized in the film plane, broken spatial symmetry of the field around the nano-contact induced by the Oersted field opens the possibility for spin wave mode co-existence including a...

NANOTECHNOLOGY is an expanding field that involves the manipulation of materials practically on an atomic scale. The properties of materials at the nano (10-9 meter) scale are different than what has been traditionally documented; the laws of quantum physics take over. This technological revolution has created exciting new opportunities in fields such as medicine, dentistry, materials science, ...

Molecular combinatory computing makes use of a small set of chemical reactions that together have the ability to implement arbitrary computations. Therefore it provides a means of “programming” the synthesis of nanostructures and of controlling their behavior by programmatic means. We illustrate the approach by several simulated nano-assembly applications, and discuss a possible molecular imple...

Nano-structuring of the surface caused by adsorption of molecules or atoms and by the reaction of surface atoms with adsorbed species are reviewed from a chemistry viewpoint. Self-assembly of adsorbed species is markedly influenced by weak mutual interactions and the local strain of the surface induced by the adsorption. Nano-structuring taking place on the surface is well explained by the noti...

Smart power grid is the future transformation of the current power systems into controlled two-way power flow networks. Smart grid allows the interactive service between customers and grid operators and permits fully integration of distributed and renewable energy resources into the electrical power system. The main objectives of the smart grid are to increase the efficiency, reliability and op...

Atomistic simulations have now become commonplace in the study of the deformation and failure of materials. Increase in computing power in recent years has made large-scale simulations with billions, or even trillions, of atoms a possibility. Most simulations to-date, however, are still performed with quasi-2D geometries or rather simplistic 3D setups. Although controlled studies on such well-d...

Abstract The surface topography of a material can influence osteoclast activity. However, the structural factors that promote activity have not yet been investigated in detail. Therefore, we osteoclastogenesis by testing various defined patterns with different dimensions and shapes. systematic patterns, made cyclo-olefin polymer, were prepared at micron-, submicron-, nano-scale groove, hole, or...
