To investigate the interaction and adsorption of drug and carbon nanotube on human serum albumin, three anti-cancer drugs ([Pd(phen)(R-gly)]NO3, R = methyl, propyl and amyl) with different hydrophobic tails and anticancer activities were selected. These drugs have better anti-tumor activity and less side effects than that known cis-platinum drug. Human serum albumin is also ...

The purpose of this work is to present elements of a design tool for field emission displays using carbon nanotubes as emitters. We use a continuum model to describe the carbon nanotubes and we use a locally one-dimensional approximation to calculate the emission current. We investigate the emission current to voltage characteristic, screening effects and the lateral spread of the emission curr...

The effects of processing conditions and apparent nanotube length on properties are investigated for carbon nanotube yarns obtained by solid-state drawing of an aerogel from a forest of multi-walled carbon nanotubes. Investigation of twist, false twist, liquid densification and combination methods for converting the drawn aerogel into dense yarn show that permanent twist is not needed for obtai...

there is no single standard technique or methodology to characterize the size, structure, number, and chemical composition of airborne carbon nanotubes.  existing analytical instruments and analytical techniques for evaluating nanoparticle concentrations cannot simultaneously provide morphology, state of agglomeration, surface area, mass, size distribution and chemical composition data critical...

The discovery of carbon nanostructures, such as nanotubes and C60 fullerenes, has given rise to a number of potential nanoscale devices. One such device is the gigahertz oscillator, comprising an inner shell sliding inside an outer shell of a multiwalled carbon nanotube, and which, at least theoretically, generates oscillatory frequencies in the gigahertz range. Following the concept of these g...

Carbon nanotube paper, sometimes referred to as bucky paper, is a random arrangement of carbon nanotubes meshed into a single robust structure, which can be manipulated with relative ease. Multi-walled carbon nanotubes were used to make the nanotube paper, and were subsequently modified with platinum using an electroless deposition method based on substrate enhanced electroless deposition. This...

in this paper, a new method is proposed for the production of mwcnts/pvc (multi-walled carbon nanotubes/ polyvinyl chloride) nanocomposites. in this method, a spray is used to produce layers of carbon nanotubes within a pvc matrix. various parameters influence the production of the nanocomposite and its mechanical properties. these parameters are studied separately and the effect of each of par...

Towards the goal of providing a continuous process for the solid-state fabrication of carbon nanotube sheets and yarns from carbon nanotube forests, we report the growth of yarnspinnable and sheet-drawable carbon nanotube forests on highly flexible stainless steel sheets, instead of the conventionally used silicon wafers. Sheets and yarns were fabricated from the 16 cm maximum demonstrated fore...

The physicochemical and droplet impact dynamics of superhydrophobic carbon nanotube arrays are investigated. These superhydrophobic arrays are fabricated simply by exposing the as-grown carbon nanotube arrays to a vacuum annealing treatment at a moderate temperature. This treatment, which allows a significant removal of oxygen adsorbates, leads to a dramatic change in wettability of the arrays,...

chemical vapor deposition (cvd) is one of the most popular methods for producing carbon nanotubes (cnts). the growth rate of cnts based on cvd technique is investigated by using a numerical model based on finite volume method. inlet gas mixture, including xylene as carbon source and mixture of argon and hydrogen as carrier gas enters into a horizontal cvd reactor at atmospheric pressure. in thi...
