Opis:
Electrochemical properties of a zinc/polyvinyl alcohol-potassium hydroxide/carbon cell have been investigated. In this cell, PVA-KOH gel has been used as an electrolyte with PVA/KOH wt.% ratio of 60:40, while zinc and carbon rods served as electrodes. The cylindrical glass vessel of length 3.0 cm and of diameter 2.0 cm has been used as a cell compartment. The current-voltage characteristics and open circuit voltage-time, charge voltage/current-time and discharge voltage/current-time studies have been done. The open circuit voltage has been observed for 160 h. It has been found that the cell shows stability and is rechargeable, too.

Opis:
The aim of this study was to investigate the effects of two different treatments, as-cast setup and solution heat treatment, on the general electrochemical corrosion resistance of Ti-7Cu alloy samples immersed in a 0.9 wt% NaCl solution at 25°C. The microstructure was examined by scanning electron microscopy and X-ray diffractometry. Corrosion behavior was tested by potentiodynamic polarization curves. Finer α' martensite and $Ti_2Cu$ intermetallic particles were provided by casting and heat treated processes, respectively. The results indicated that only corrosion potential is significantly more noble in the heat treated sample, but other characteristics are only slightly different.

Opis:
In this study, we report on the optimization and characterization of chloroform soluble calix[4]arene derivative as a humidity sensor based on electrical properties. Due to the fact that calix[4]arene molecules are nonconductive, we modified the calix[4]arene molecules with carbon nanotubes with electrostatic bond in order to increase the conductance of calix[4]arene molecule (5,11,17,23-tetra-ter-butyl-25,27-dehydrazinamidcarbonilmetoxy-26,28-dehydroxy-kalix[4]aren). Using photolithography technique, we fabricated interdigitated gold electrodes with 3 micrometers separation to investigate the electrical properties of carbon nanotubes modified calix[4]arene molecule where we used dropcast method to form a thin film of carbon nanotubes modified calix[4]arene molecule on the gold electrodes. Our reproducible experimental results indicated that the chloroform soluble carbon nanotubes modified calix[4]arene films have great potential for humidity sensing applications at room temperature operations.

Opis:
This study focuses on the characterization and optimization of calixarene modified carbon nanotube thin films for gas detection. Calixarene molecules were synthesized individually by considering their functional groups to attract the gas. Calixarene modified carbon nanotube based sensors were fabricated using drop-casting method on a quartz crystal microbalance gold electrode. Carbon monoxide, carbondioxide, oxygen and dry air were used as active gases for adsorption process, while high-purity nitrogen gas was used for desorption process. The selectivity and sensitivity of calixarene modified carbon nanotube are investigated in detail. Our experimental results show that functional calixarene modified carbon nanotube coated quartz crystal microbalance sensors are very sensitive and selective to gas of $CO_2$ at room temperature operation.

Opis:
In this study, a functional product with aromatic oil and vitamins for use at aromatherapy and spa centers or personal care has been designed to improve life quality of users by using multifunctional products with good odor, moisturizing, relaxation, anti-aging effects. For this purpose, commercial berry berry oil was capsulated in β-cyclodextrin, and then applied to 100% cotton towel fabric. Quartz crystal microbalance sensors were used to investigate odor adsorption kinetics on modified textile materials for the first time. The frequency responses vs. time plot shows clear linear step responses to the change in the concentration of odor molecules coming from the container filled with berry berry applied textile. The results also reveal that $TiO_2$ coated quartz crystal microbalance sensors can be used as e-nose to sense odor from textile coated with berry berry oil containing β-cyclodextrin capsules.

We synthesized both the $V_{2}O_{5}$ xerogel and the composite $V_{2}O_{5}$ xerogel/C starting from the solution of $V_{2}O_{5}$ in hydrogen peroxide. After the characterization by XRD, thermal (TGA-DTA), SEM methods and by particle size analysis, the investigation of $Li^{+}$ and $Mg^{2+}$ intercalation/deintercalation reactions in an aqueous solutions of $LiNO_{3}$ and $Mg(NO_{3})_{2}$ were performed by cyclic voltammetry. The composite material $V_{2}O_{5}$ xerogel/C displayed relatively high intercalation capacity, amounting to 123 mA h $g^{-1}$ and 107 mA h $g^{-1}$, in lithium and magnesium salt solutions, respectively.

The tunneling probability through a double-barrier ZnSe/ZnTe structure is calculated using both wave-packet time dependent quantum mechanics and stationary planar-wave approximation. The obtained I-V characteristics are compared and very good consistence in resonant peaks width and position is observed. The absolute value of tunneling probability obtained in time-dependent and stationary approach is also similar.

Opis:
The solution of the one-dimensional Schrödinger wave equation is presented for the potential-energy function that describes a double delta-barrier under the application of a constant electrical field perpendicular to it. The transfer matrix technique is employed to determine the transmission coefficient in an analytical form. Some attributes of the transmission coefficient are established. The transmission coefficient is shown to exhibit maxima and minima, the conditions for maxima and minima in the transmission coefficient are discussed. The current-voltage characteristic of the biased double delta-barrier is calculated numerically. It is found to exhibit the same oscillatory behaviour as the transmission coefficient when the voltage applied to the double delta-barrier is increased. The width of the double delta-barrier is shown to modulate the peak-to-valley ratio in the current-voltage characteristic.

Opis:
The tunneling probability in double barrier heterostructures can be affected by various effects. One of the most significant is presence of the accumulation layer placed before the structure. The presented time-dependent results show that charge trapped in the accumulation region oscillates in the triangular quantum well and tunnels sequentially through the double barrier structure resulting in periodical changes of the charge density right to the heterostructure.

Opis:
The tunneling phenomena in double barrier heterostructures can be affected by various effects. In this paper the effect of the intense THz radiation on the electron dynamics in the double barrier heterostructure is investigated. For the low frequency radiation the shift in the energy scale of the resonant tunneling peak together with its broadening is observed. For the high radiation frequency the multipeak structure is obtained. The interaction with radiation quanta leads to sequential tunneling and the transmitted wave function consists of single separated wave packets.

In this paper we perform a detailed study of the transport of hot electrons in the double barrier heterostructures with the presence of a collector barrier. This system is considered as a double barrier resonant tunneling device. The electron is described by time-dependent Schrodinger equation, which allows us to study detailed dynamics of the carriers. The influence of an energy step in the collector area of the device on the tunneling probability is investigated. The significant role of dissipation due to electron-phonon interactions is presented.
