Monte-Carlo simulation of biomolecules' fluid dynamics in a specially designed biosensor comprising plurality of nanowires is presented. It is found that an AC external field can substantially improve the performance of the biosensor; e.g., the capture efficiency by 4.5-times and the detection speed by 24.8-times.
Brownian motion had been a topic of interest since the last two centuries and researchers have investigated the motion considering size, environment and mass. Few attempts considering the non-rigidity had been published to establish correlation between variance and nanoparticle parameter like size, mass and non-rigidity (stiffness) [1] [2]. In continuation, the present work investigates the significance...
Resistive switching memory devices is a promising candidate for next generation data storage. The use of nontoxic and natural available biomaterials are prospective building block for environment friendly, biocompatible and biodegradable electronic devices. The fabrication and characterization of protein based Al/Azurin/ITO/PET flexible memory device is presented here. We observed significant bistable...
The paper describes an approach to fabricate large area Graphene (Gr)/MoS2 on paper using simple, cost effective solution processed hydrothermal method. Gr was deposited on paper using dip coating method followed by hydrothermal growth of 2D MoS2 on Gr. Raman analysis confirmed the growth of few layer MoS2. IV characteristic of MoS2, MoS2/Gr revealed higher conductivity for Gr/MoS2. Under illumination...
Recently the new class of two-dimensional (2D) layered materials with low-symmetry crystal structure has attracted much attention. Their unique electrical characteristics along different in-plane crystal directions provide novel prospects for developing electronic devices. In this paper, we will review the research from our group on studying basic properties of these low-symmetry 2D materials and...
Graphene has attracted great interest for application in spintronics due to its intrinsic low spin-orbital and hyperflne interaction. The graphene spin filter, which permits the transport of electrons with certain spin only, has been used to realize electron spin-based logic devices. The spin polarity of a spin filter has strong correlation with the parallel or anti-parallel magnetic alignment of...
The presence of nanoparticles within an ultrasonic field has been previously shown to cause ultrasound to preferentially destroy cancerous cells over corresponding normal cells. Such treatment, termed nanoparticle-assisted ultrasound therapy (NAUT), has now been applied to subcutaneously implanted tumors in mice. Xenografted tumors were exposed to therapeutic ultrasound, with and without intratumoral...
In this paper, we focus on the possibilities of using bionanomachines to treat neuronal (brain) disorders. Neuronal networks in the brain are an excellent example of nanonetworks that control all major functions of a human body, thereby offering a sound physical and mental health of a human being. In the brain, approximately one hundred billion neurons are connected three-dimensionally with other...
Memristors are passive elements that allow us to store information using a single element per bit. However, this is not the only utility of the memristor. Considering the physical chemical structure of the element used, the memristor can function at the same time as memory and as a communication unit. This paper presents a new approach to the use of the memristor and develops the concept of resistive...
This paper presented a method for multiwalled carbon nanotube(MWCNT) and graphene fusion by applying current to the electric circuit system inside scanning electron microscopy (SEM). The MWCNT was picked up from CNT bulk and the graphene flake was exfoliated from graphite by nanorobotics manipulation system. The current was applied to the two ends of carbon nanotube and graphene. The C-C bonds at...
Nanoparticles of several different compositions and lattice structures that have been characterized by transmission electron microscopy, scanning/transmission electron microscopy, X-ray spectroscopic (EDX) analysis, and diffraction patterns may be conjugated to biological targeting agents for use as labels that can localize and differentiate multiple targets at nanometer resolution in complex biological...
In this work, we develop and employ a multiscale-multiphysics simulator (based on coupled VFF molecular mechanics, 10-band sp3s∗-spin tight-binding formalism, many-body full configuration interaction, and a TCAD transport module) to study and compare the performance of realistically-sized multiple-quantum-well wurtzite InGaN LEDs in polar (c-plane) and nonpolar (a-plane) crystallographic directions...
A nanostructured disordered FeAlSn solid solution of Fe-26% Al-2% Sn composition was obtained from elemental Fe, Al and Sn powders using a high-energy ball mill. X-ray diffraction and electron microscopy supported by Mössbauer spectroscopy techniques have been applied to follow changes in the microstructure, phase composition and magnetic properties in dependence on milling time. The transformation...
In this work, we first calculate the effects of uniaxial strain on polar optical phonon (POP) scattering rates in monolayer M0S2. We then study the effects of strain on electron transport in a monolayer MoS2 based FET device employing a fully 3-D particle based quantum-corrected Monte Carlo device simulator. Our results show that, for both E+ and E Raman modes, the current first increases for up to...
The characteristics of nano-acoustic resonators are analyzed to assess their use in sensing the acoustic properties of the near-particle environment of nanoparticles embedded in various matrices. This type of information is critical to understanding the chemo-physical interactions between these matrices and particles in polymer matrix nanocomposites designed to provide specific optical and chemical...
Tea is very popular in the world owing to its numerous therapeutic effects in lowering blood pressure, decreasing blood coagulation, repairing oxidative damage among many others. Due to their promising biodegradability, biocompatibility and antimicrobial activity, tea nanoparticles isolated from tea leaves have a great potential for various biomedical applications. Small molecules like polyphenols...
We report a fabrication method of nanoscale quantum-dot (QD) organic light-emitting diode (OLED) structure suspended on a monolayer hexagonal boron nitride (h-BN) sheet on nano-hole-patterned SiO2/Si substrate. In our proposed OLED, the junction area is defined by a non-lithographically patterned oxide layer on Si substrate. We utilized self-organized gold nanoparticles to create nanoscale etch windows...
Atomic force microscope (AFM) is a useful apparatus for measuring interaction forces between an AFM tip and samples at nanoscale. These forces can be classified into a normal force and a lateral force based on the deformation of AFM cantilever. The reliability of the measurement result is influenced by calibrating the spring constant of the AFM probe directly. However, it is still a challenge to quantitative...
Ceramic nanomaterials are attractive due to the functional properties such as optical, electronic, thermal behaviors as well biocompatibility. In this work three kinds of functional ceramic nanocrystals, i.e. SiC (hexagonal platelet-like), TiC (truncated-octahedral) and TiN (cubic structured) were synthesized by a facial DC arc-discharge plasma process. Preparation atmospheres were chosen for the...
