The experiments on the fabrication of materials based on the Ti–3Al–0.5Ta and 3Ti–2Al–Ta systems by self-propagating high-temperature synthesis (SHS) are performed. The influence of the composition of the initial mixture, dispersity of powders, and preliminary mechanical activation on the phase composition and structu…
In this work we used an atmospheric pressure dielectric barrier discharge plasma to perform treatments of poly(dimethylsiloxane) (PDMS) surfaces in order to improve the adhesion between the samples. The results show that different conditions of plasma treatment can lead to a better adhesion between the PDMS surfaces.…
Applying appropriate electric pulses to a nematic liquid crystal confined between plates, the bulk order reconstruction can occur, a mechanism allowing the switching between topologically different nematic textures without any director rotation. Using a moving mesh finite element method we describe the order tensor dy…
We have developed a 3D coaxial flow-focusing nozzle device for the mass production of monodispersed collagen microspheres and chemically crosslinked them using EDC (1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide) and N-hydroxysuccinimide (NHS). The size of the microspheres was varied between 200 μm and 600 μm by adjus…
Microelectrode arrays have extensive applications in the biomedical field. These applications range from the study of the influence of drugs in cell cultures to neuro-implants for attenuation of diseases, such as Parkinson's disease and epilepsy. The main block of the analog front-end attached to the MEA is the bioamp…
Multielectrode arrays (MEAs) are widely used for recording biopotentials, with an ongoing research effort to improve their characteristics and performance. In this spirit, we are currently investigating a novel concept for a liquid crystal-based optical electrode (optrode) that has the potential to overcome some of th…
Biobotics is an emerging and useful advent in the field of robotics which harnesses the mechanical power of live invertebrates and benefits from them as "working" animals. Most biobotic applications rely on neural or muscular stimulation through implanted electrodes for achieving direct control of their locomotory beh…
A new copper phthalocyanine, namely 9(10),16(17),23(24)-tri-tert-butyl-2-[acetynyl-(4-carboxy)phenyl]phthalocyaninatocopper and its related free base have been synthesized as potential stable blue dyes for dye sensitized solar cells. The molecule structure consists on an unsymmetrically-substituted macrocycle bearing…
The synthesis of new metalated diporphyrinylamines is described. The electronic ≪communication≫ through the amino function linking the two porphyrins was clearly demonstrated by electronic spectroscopy. In addition, intramolecular magnetic interactions were measured between two copper(II) ions located in the two linke…
Metamaterial have been emerged as one of the potential candidates for enhancing the performance of wireless power transfer (WPT) applications. Later, the high-Q value presented by cavity mode resonance of passive metamaterials has been proposed for sub-wave length field localization. In contrast to using passive metam…
This paper proposes the spatial filter with FSS(Frequency Selective Surface) for orthogonal polarization conversion such as converting the vertical polarization to horizontal polarization. It is found that multilayered loop-slot type FSS having band-pass filter characteristics realize orthogonal polarization conversio…
Since the emergence of microfluidic platforms sensors integration has been a major challenge. With the advances in miniaturization of these platforms, there is a need for solutions to integrate various optical components in order to build sensors, which will offer different detection characteristics such as several em…
Electron micrography (EM) is an important method for determining the three-dimensional (3D) structure of macromolecular complexes and biological specimens. But there are several limitations such as poor signal-to-noise, limitation on range of tilt angles and sub-region subject to electron exposure, unintentional movem…
Tissue engineering is the field of functional restoration of tissue structure and physiology for impaired or damaged tissues because of cancer, disease, and trauma. The field has gained importance due to the inadequate supply of organs and tissues for patients requiring organ and tissue replacement. Research in this f…
Recently, biocompatible and amphiphilic poly(organophosphazene) (PPZ) has been suggested as a drug delivery carrier since it can be easily modified to achieve desired chemical properties. In this work, we newly designed a PPZ with balanced hydrophilicity and hydrophobicity by modulating the mole ratio of hydrophilic t…
Active matrix organic light emitting diode (AMOLED) displays based on amorphous indium-gallium-zinc oxide thin-film transistor (a-IGZO TFT) pixel circuit encounter problems as instability of threshold voltage (VT) under gate voltage bias-stress, the non-uniformity of mobility (μ) resulting from the large area TFT scal…
As the weakest parts in through silicon via (TSV) structures, solder bump joints bear cyclic thermal stresses under power cycling in service, which contribute to the fatigue of them. Meanwhile, the dimensions of solder bump joints keep shrinking due to the miniaturization of electronic systems and products. The size e…
While the size of electronic devices continues to decrease and the I/O number per chip keeps increasing, the size and pitch of solder bumps are required to be as small as possible. This case gives rise to great concerns on their quality and reliability. As a 3D integration alternative to solder bumps, Cu-pillars have…
The structural and electronic properties of bilayer boron-phosphide (BP) and the effects of different stacking orders on the electronic structure of bilayer BP are investigated employing first-principles methods. The computed results show that the band structure of bilayer BP included band gap depends on the stacking…
The elastocaloric effect in the Bi4Ti3O12(BIT) ferroelectric nanoparticle with vortex domain structure was studied using a phase field simulation in this work. A transformation from the negative elastocaloric effect to positive elastocaloric effect which is associated with vortex domain structure is found under the un…
