Superparamagnetic iron oxide has been applied in different fields for various reasons. Its abundant availability, non-toxic properties, environmentally friendly and good chemical stability in aqueous medium are beneficial for water treatment applications. In addition, its low bad gap (2.3 ~ 2.4 eV) has contributed to highly possible electrons-holes activation under the visible light spectrum. On the realization of iron oxi Read More

Background: Spherical contacting surfaces are often designed to increase the contact surface area and bearing ability, and frequently suffer fluctuating loading, which will play an important role in tribological properties. Objective: Effects of high-frequency fluctuating loading on friction and wear performance of spherical- surface contact sliding pairs should be experimentally investigated. Methods: Bench tests with the d Read More

Background: Over the last few decades, reversible logic system/circuits have received considerable attention in the diversified fields such as nanotechnology, quantum computing, cryptography, optical computing and low power design of VLSI circuits due to their low power dissipation characteristics. Methods: In this paper, we proposed the design of reversible shift register (SR) i.e. serial-in-serial out (SISO), serial-in-par Read More

Objective: The objective of the present work was to develop transethosomes loaded with propranolol hydrochloride using Lipoid S100 as phospholipid, and oleic acid as permeation enhancer and evaluate them for prolonged release effect, in-vitro skin permeation, and in-vivo plasma concentration. Methods: Transethosomes loaded with propranolol hydrochloride were prepared by homogenization method. Furthermor Read More

Background: Measuring tartaric acid in liquid food, such as fruits or fruit products is of great importance for assessing the quality of the food. Objective: The aim of the research is to obtain polyaniline/Cu bismuthate nanoflake composites by an in-situ polymerization route for the electrochemical detection of tartaric acid. Methods: Polyaniline/Cu bismuthate nanoflake composites were prepared by in-situ aniline pol Read More

Background: Main concern in efficient VLSI circuit designing is low-power consumption, high-speed and noise tolerance capability. Objective: In this paper, two efficient and high-performance topologies are proposed for cascaded domino logic using carbon nanotube MOSFETs (CN-MOSFETs). The first topology is designed to remove the intermediate charge sharing problem without any keeper circuit, whereas the second one holds Read More

Aim: Vanadium oxide nanofibers have been manufactured by the sol–gel electrospinning method followed by the thermal treatment in air and argon. Materials and Methods: The samples are characterized by optical, laser confocal and scanning electron microscopy, energy-dispersive X-ray elemental analysis, X-ray diffraction, cyclic voltammetry, and electrical conductivity measurements. Results: The obtained VO2 nanofibe Read More

Background: Fractional order Butterworth and Chebyshev (low-pass filter circuits, highpass filter circuits and band-pass filters circuits) types of first and second order filter circuits have been simulated and their transfer function are derived. The effect of change of the fractional order α on the behavior of the circuits is investigated. Objective: This paper presents the use of fractional order capacitor in active filters.
