Microtubules play an important role in intraneuronal communication. A barrier to microtubule mediated neuronal transport can initiate dementia. The nanoscale modeling of these biological events is expected to be useful for healthcare applications and auxiliary biosensor based diagnostics. Here, we report a model system by using an in vitro bio-motility assay to predict events related to dementia at...
The etching properties of C3F6, C3HF5, C3H2F4, and C3H3F3 were evaluated to investigate the effects of replacement of fluorine atoms to hydrogen atoms in the unsaturated fluorocarbon. Etching rates of SiO2 were decreased, and deposition rates of CFn films on p-Si wafer were increased with increasing the hydrogen atoms in the molecule. XPS spectra show that the contribution of strong C-C bond in the...
Alumina(Al2O3)-coated segmented polyurethane (SPU) sheet is prepared for the application to bioengineering by using both preparation methods of atomic layer deposition for Al2O3 coating and electrospinning for SPU scaffold sheet. Its fine blood compatibility was performed on in-vivo test during long term.
In the present investigation, silver nanoparticles (SNP) were synthesised using Dipteracanthus prostratus (Poir.) Nees, leaves extract and were characterised using UV-Visible spectroscopy, High resolution transmission electron microscopy (HR-TEM), and X-ray diffraction. The UV-Vis analysis of nanoparticles shows absorption peak at 412 nm. HR-TEM results showed them to be spherical - ellipsoidal in...
H+ emission from the sharpening glass fiber was successfully observed. Here, ion current density and chemical functionalization via ion irradiation are presented.
Crater formations with gas cluster ion beam (GCIB) were used for non-contact hardness measurement of thin films. The crater inner diameter formed with size-selected Ar cluster ions decreased with inverse cube root of film hardness. When the total acceleration energy was the same, cluster size did not affect the crater inner diameter. In addition, high ionization electron voltage (Ve) cause wide distribution...
The present investigation reports a facile method for the biosynthesis of gold nanoparticles from the rind extract of Garcinia mangostana, a medicinal plant which acts as a reducing agent. It was observed that the aqueous gold ions, when exposed to the rind extract of G.mangostana were reduced in the solution, thereby leading to the formation of gold nanoparticles (GMREGNP). The structural characterization...
In the liquid phase synthesis of metallic nanoparticles by electroless deposition, the morphology of product is strongly dependent on numerous synthesis conditions; for example, the type or quantity of solvent, precursor, reductant and dispersant species. In this work, the influence of the surface area of precursor on the size distribution of synthesized nanoparticles was investigated using a kinetic...
We introduce a state-of-the-art self-aligned contact (SAC) process and patterning process developed by new patterning technology using Atomic Layer Etch (ALE) and Atomic Layer Deposition towards 5/7nm generation.
In this work ion-selective arrays based on spray-coated electrolyte-gated carbon-nanotube field-effect transistors will be used in an example application for water quality assessment. Several cations like Na+, K+, Ca2+ and anions like Cl− and NO3− are detected with the ion-selective sensor arrays in different bottled mineral waters. For the ion-selective arrays the sensing results of two different...
To improve the image contrast, the so-called contrast agents (CAs) are often used in magnetic resonance image (MRI). CAs are generally paramagnetic or superparamagnetic nanoparticle suspensions. To increase the applicability of low field nuclear magnetic resonance (LFNMR) or LFMRI system, CAs also have been introduced to enhance the image contrast. In this work, we synthesized the γ-Fe2O3/Au core/shell...
Time-controlled pulse plasma CVD has been developed aiming for the mass production of narrow chirality distributed single-walled carbon nanotubes (SWNTs). Through the comparison of continuous plasma CVD and pulse plasma CVD, it is found that the amount of SWNTs can be increased in keeping with the initial narrow chirality distribution by repeating pulse plasma CVD. The effects of pulse time parameter,...
Many difficulties and limitations of surface processing by traditional ion beam techniques are associated with the electrical charges that are fundamental to ion acceleration. Flux neutralization approaches used to minimize space charge repulsion effects and neutralization methods employed to avoid surface charge accumulation and damage phenomena complicate the use of ion beams in many situations,...
In this article, we report a Field Effect Transistor (FET) with Aluminum doped graphene channel. The graphene is doped by spin coating a chemical dopant solution which tailored the electrical properties of graphene, such as transfer characteristics and output characteristics. The Doping of graphene was successfully verified by X-Ray photoelectron spectra (XPS) measurements. The testing results showed...
All-solid state Li ion batteries are expected as one of next-generation rechargeable batteries since they have the potential to achieve high energy density and are free of risk of a flammable liquid electrolyte. The Li ion batteries cathodes, such as LiCoO2, change their volume during insertion or extraction of Li ions. Therefore, mechanical stress can be induced at the electrode/electrolyte interface...
High energy density secondary batteries are key devices and becoming more important for mobile applications such as electric vehicles, drones and robots. In this paper, investigations of new materials and device concepts are reported on the all solid state lithium ion secondary batteries and their wide applications to mobile technologies are discussed.
Nanoscale electronic devices will require the placement of dopants in a predetermined location, namely, a single atom control to explore novel functions for future nanoelectronics. Deterministic doping method, i.e. single-ion implantation, realizes ordered arrays of single-atoms in silicon, diamond and other materials, which might provide opportunities to single-dopant transport or single-photon source...
We study the impact of random dopant fluctuation (RDF) on electrical characteristics of 10-nm-gate high-κ/metal gate gate-all-around silicon nanowire MOSFET devices. To provide the best accuracy of device simulation, model parameters are validated by using full quantum mechanical simulation and calibrated with experimental results. Physical mechanism of RDs inside channel and penetration from the...
