Histidine-containing peptides self-assemble on the surface of monolayer protected gold nanoparticles to form a catalytic system for transesterification reactions. Self-assembly is a prerequisite for catalysis, since the isolated peptides do not display catalytic activity by themselves. A series of catalytic peptides and substrates are studied in order to understand the structural parameters tha...
an oriented perfect path double cover (oppdc) of a graph $g$ is a collection of directed paths in the symmetric orientation $g_s$ of $g$ such that each arc of $g_s$ lies in exactly one of the paths and each vertex of $g$ appears just once as a beginning and just once as an end of a path. maxov{'a} and ne{v{s}}et{v{r}}il (discrete math. 276 (2004) 287-294) conjectured that ...
Infected Tissue Regeneration In article number 2205941, Xibo Pei, Jian Wang, and co-workers report a silver nanoparticle (AgNPs) modified metal-organic-framework nanosystem ([email protected]) with enhanced photodynamic efficiency chemotherapy ability for infected tissue regeneration. The performance under visible light disrupts bacteria translation process. process causes destructive effect on...
We begin with an introduction of superconductivity by giving a brief history of the phenomenon. The phenomenological Ginzburg–Landau theory and the microscopic theory of Bardeen, Cooper and Schrieffer are outlined. In view of recently available multi-band superconductors, relevant theories of both types are discussed. Unlike the traditional GL theory an extended GL theory is developed relevant ...
We present a model describing the dynamics of a thermally activated nanoelectromechanical device. The nanosystem consisted of two coaxial carbon nanotubes of disparate lengths. The presence of strong thermal inhomogeneities induced motion of the shorter nanotube along the track of the longer nanotube. A model combining the actions of frictional, van der Waals, and thermal forces and the effects...
We predict and quantitatively evaluate the unique possibility of concentrating the energy of an ultra-fast excitation of a nanosystem in a small part of the whole system by means of coherent control (phase modulation of the exciting ultra-short pulse). Such concentration is due to dynamic properties of surface plasmons and leads to local fields enhanced by orders of magnitude. This effect exist...
