the continuum based approaches don’t provide the correct physics in atomic scales. on the other hand, the molecular based approaches are limited by the length and simulated process time. as an attractive alternative, this paper proposes the fixed interfacial multiscale method (fimm) for computationally and mathematically efficient modeling of solid structures. the approach is applicable to mult...

The ability to manipulate biological cells and micrometer-scale particles plays an important role in many biological and colloidal science applications. However, conventional manipulation techniques, such as optical tweezers, electrokinetic forces (electrophoresis, dielectrophoresis (DEP), and traveling-wave dielectrophoresis), magnetic tweezers, acoustic traps, and hydrodynamic flows, cannot a...

We present a new approach using genetic algorithms, neural networks, and nano robotics concepts applied to the problem of control design for nanoassembly automation and its application in medicine. As a practical approach to validate the proposed design, we have elaborated and simulated a virtual Environment focused on control automation for nano robotics teams that exhibit collective behavior....

The surface morphology of micro- and nano- scale fiber determines its application to a great extent. At present, variety secondary microfibers nanofibers, such as porous, wrinkle, groove so on, have been prepared. Among them, grooved fibers are attracting more attention because their unique properties. In this paper, we review the literature on due void-based elongation, wrinkle-based collapsed...

Abstract Optical tweezers were developed in 1970 by Arthur Ashkin as a tool for the manipulation of micron‐sized particles. Ashkin's original design was then adapted variety purposes, such trapping and biological materials [1] laser cooling atoms. [2,3] More recent development has led to nano‐optical tweezers, particles on scale only few nanometers, holographic which allow dynamic control multi...

Theoretical analysis and Computer simulations have proven to be cost-effective and powerful tools in scientific studies of materials, particularly at nano-scale where synthesis of nano-structures, interpretation of their observed character and exploration of new structures are not always straight forward. We present here fundamental principles of techniques used today for computational simulati...

Conventional atomic force microscope nanomanipulation is inefficient because of the serial imaging/manipulation operation. We present here a parallel imaging/manipulation force microscope PIMM to improve manipulation efficiency. The PIMM is equipped with two individually actuated cantilevers with protrudent tips. One cantilever acts as an imaging sensor by scanning nano-objects and tip of the o...

A conventional atomic force microscope (AFM) has been successfully applied to manipulating nanoparticles (zero-dimensional), nanowires (one-dimensional) or nanotubes (one- or two-dimensional) by widely used pushing or pulling operations on a single surface. However, pick-and-place nanomanipulation in air is still a challenge. In this research, a modified AFM, called a three-dimensional (3D) man...

The definition of wear has been proposed as a progressive loss of materials due to mechanical action of two bodies while in contact. Several researchers have also suggested the definition of wear as the progressive loss of substance from the operating surface of a body occurring as a result of relative motion against a solid, liquid or gaseous counter body at the surface. Thus, it can be stated...
