Including graphene in electronic devices can modify their electrical properties particularly those associated with conductivity and band properties. Since graphene has a unique atomic structure that generates a delocalized electron cloud, it shows high mobility and an extraordinary band structure. Thus, many types of…
Graphene, the one-atom-thick sheet of sp2-hybridized carbon atoms, ever since its advent in the scientific world, has enjoyed a star status. Owing to its unique structure, graphene is known to have extraordinary physical and chemical properties, such as very high electrical conductivity, exceptionally high surface are…
Platinum group metals (PGMs) are used extensively as catalysts, employed in several sectors of the world energy economy. Fuel cells employing PGM catalysts show promise as power sources in the proposed hydrogen economy, using alcohols as hydrogen storage media. Currently, the most economically important application fo…

Abstract The main objective of this study is to obtain and validate a mathematical model to describe a complex homogeneous Sono-Fenton (HSF) process used for the removal of 4-chlorophenol model pollutant from aqueous effluents. The investigated process parameters (acoustic amplitude, power density depending on the sur…
Samples of Bi2V0.9Co0.1-xZnxO5.35, 0.02 ≤ x ≤ 0.08 with layered Aurivillius structure were synthesized successfully by sol-gel citrate method. Structural and electrical characterization of compositions has been investigated by X-ray diffraction, thermogravimetric analysis–differential scanning calorimetric (TGA–DSC) a…
In the present work, we report the effect of size and dimension on catalytic activation energy (EC) of some dioxide nano structured materials using a simple analytical model. We report the variation of catalytic activation energy with the size from 1 nm to 30 nm and 0-,1-,2-dimensions of TiO2, CeO2 and SnO2 nanopartic…
This paper investigates Nb-Si metal composite films with various proportions of niobium in comparison to pure Nb films. Films were prepared by two-target RF-DC magnetron cosputtering deposition. The optical properties and residual stress were analyzed. A composition of Nb(0.74)Si(0.26) was chosen toward the design and…
Spin and pseudospin properties of monolayer graphene, when both the exchange and extrinsic spin–orbit (SO) interactions are taken into account, are analyzed within a framework of geometric algebra. The rotor equations for even and odd parts of electron bispinor are constructed in three-dimensional (3D) Euclidean space…
A chiral silver(I) complex was synthesized from the reaction of a chiral amino alcohol derived from (+)-camphor and silver nitrate, with the structure unambiguously disclosed by X-ray analysis and 2-D-NMR experiments. In this complex, the amino alcohol molecule is a monodentate ligand through the amino nitrogen, requi…
ABSTRACT Self‐assembled films of brush‐like amphiphilic copolymers with varying hydrophobic contents (fc12, 10–90 mol %) were prepared on glass slides. In addition, the surface tension and contact angles of solutions of these copolymers were also investigated. By combining the data obtained investigating the morpholog…
The acoustic cavitation phenomenon is a source of energy for a wide range of applications such as sonoluminescence and sonochemistry. The behavior of a single bubble in liquids is an essential study for acoustic cavitation. The bubbles react with the pressure forces in liquids and reveal their full potential when peri…
Liposome plays an important role in medical and pharmaceutical science as e.g. nano scale drug carriers. Liposomes are vesicles of varying size consisting of a spherical lipid bilayer and an aqueous inner compartment. Magnet-driven liposome used for the targeted delivery of drugs to organs and tissues. These liposome…

This study reports the synthesis of size-controlled Fe-MFI (Fe-substituted zeolites with the MFI topology) and their catalytic performances for DTO (dimethyl ether-to-olefins) reaction. The amount of HCl and aging temperature were decisive factors to control the particle size of Fe-MFI in the range of 50 nm to 600 nm.…
Polycrystalline films ZnO has been grown onto glass substrates by chemical spray pyrolysis (CSP) method. They were given heat treatment at different temperatures and constant time and for different times with constant temperature in air. The change in structural and optical properties was studied by means of X-ray dif…
In this paper preparation of good quality transparent conductive ZnO thin films by post-oxidation of vacuum evaporated Zn, on glass and silicon (p-type) as substrates, the oxidation was achieved in a short time (90 sec) which is known as rapid thermal oxidation. One growth parameter has been considered to specify the…
