Advances in modelling and analysis of nano structures: a review

Abstract

<jats:title>Abstract</jats:title><jats:p>Nanostructures are widely used in nano and micro-sized systems and devices such as biosensors, nano actuators, nano-probes, and nano-electro-mechanical systems. The complete understanding of the mechanical behavior of nanostructures is crucial for the design of nanodevices and systems. Therefore, the flexural, stability and vibration analysis of various nanostructures such as nanowires, nanotubes, nanobeams, nanoplates, graphene sheets and nanoshells has received a great attention in recent years. The focus has been made, to present the structural analysis of nanostructures under thermo-magneto-electro-mechanical loadings under various boundary and environmental conditions. This paper also provides an overview of analytical modeling methods, fabrication procedures, key challenges and future scopes of development in the direction of analysis of such structures, which will be helpful for appropriate design and analysis of nanodevices for the application in the various fields of nanotechnology.</jats:p>

Synthesis of functionalized carbon nanotubes for fluorescent biosensors

“…CNTs were synthesized by catalytic-chemical vapor deposition (CCVD) [4,9,10]. The apparatus used in the synthesis process was a three-zone horizontal furnace, allowing temperature control of each zone.…”

“…CNTs also find a number of medical applications [4,5]. After proper functionalization (surface modification), it is possible to give them new biocompatibility properties.…”

“…Initially, the possibility of using such carriers in cancer therapy and treatment of viral infections was studied. Currently, the possibility of using CNTs as carriers in immunotherapy or gene therapy has been also proven [1,3,4].…”

Beam Theory of Thermal–Electro-Mechanical Coupling for Single-Wall Carbon Nanotubes

“…There is p lenty of research on the small-scale effect, but these studies simultaneously introduce many controversies [ 4 , 9 , 12 , 13 , 14 ]. In most existing research, the classical beam model is modified through non-local theories to consider the small-scale effect [ 4 , 14 , 15 ]. These theories mainly include the stress gradient theory, , and the strain gradient theory, .…”

Surface hydrophobicity and oleophilicity of hierarchical metal structures fabricated using ink-based selective laser melting of micro/nanoparticles

“…The surface properties of such components are critical to their performance. Nanostructures fabricated using nanowires, nanotubes, nanobeams, nanoplates, graphene sheets, and nanoshells could provide unique capabilities for nano-sensors, probes, and surface functionalities [1]. Surface functionalities such as super-hydrophobicity is an interfacial property with a water contact angle (CA) greater than 150°, enabling many applications in industrial and biomedical processes [2][3][4][5][6].…”
