Abstract Recently, nano-materials have received increasingly more attention for their potential applications as structural and functional materials. The unique mechanical properties of CNTs, their high strength and stiffness and the enormous aspect ratio provide potentials for the improvement of the mechanical propert…
Indium oxide nanowires encapsulated in amorphous carbon nanostructures have been synthesised on iron coated indium tin oxide substrate via the chemical vapour deposition of acetylene (C2H2). The growth of indium oxide nanowires encapsulated in amorphous carbon nanostructures via solid–liquid–solid mechanism was sugges…
A compact and broadband three-port left handed coplanar waveguide power divider is presented. The left handed power divider is designed using a simple left handed T junction. The left-handed T junction power divider/combiner has the advantages of its broadband (2.5 times wider bandwidth) and compact size (50% size red…
Abstract The complex cis‐[RuIII(dmbpy)2Cl2](PF6) (2) (dmbpy = 4, 4′‐dimethyl‐2, 2′‐bipyridine) was obtained from the reaction of cis‐[RuII(dmbpy)2Cl2] (1) with ammonium cerium(IV) nitrate followed by precipitation with saturated ammonium hexafluoridophosphate. The 1H NMR spectrum of the RuIII complex confirms the pres…
To analyze and explain the gradual reset switching property of the bipolar switching resistive random access memory (RRAM) for multilevel cell (MLC) operation, the effect of the amount of plasma oxidation on the gradual reset switching behavior of the Al/TiO2-based RRAM cell structure is investigated. The device that…
Abstract Adhesive bond strength depends on adherend, adhesive and interphase zone. Adhesive joint includes bonded areas or binding edges across bonded layer. Research of adhesive bond strength focuses on understanding the properties of bulky paper associated with formation of the interphase and adhesive joint failure…
The derivation of an equivalent 3-D Von Neumann equation and the corresponding kinetics equation in terms of geometrical characteristics of a grain is shown and the formulation is provided in the framework of the statistical theory of grain growth. The topological relationships between number of grain faces, grain siz…
New fungicidal and antimicrobial siloxane oligomers were prepared on the basis of γ-aminopropyltriethoxysilane and a series of bisphenols. Chemical immobilization of these oligomers on the surface of various fabrics was studied with the aim to develop textile materials resistant to microbiological degradation.
Abstract Two compounds, namely [Cd(HINA)2(µ2‐H2O)(H2O)2]2[SiW12O40]·6H2O (1) and [Co(HINA)3(H2O)3][Co(HINA)2(H2O)4][SiW12O40]·2H2O (2), have been synthesized from the aqueous mixture containing H4SiW12O40, isonicotinic acid (HINA), and M(CH3COO)2 (M=Cd and Co). The compounds have been characterized by elemental analys…
Here, we report the development of a simple, small, fast heating, and portable, homemade, inert gas (Ar) atmospheric annealing setup. Instead of using a conventional heating element, a commercial soldering rod having an encapsulated fast heating heater is used here. The sample holder is made of a block of stainless st…
The results of static magnetic susceptibility studies of spacer-armed dinuclear copper(II) complexes with dicarboxylic acid acylhydrazones are described. Weak exchange coupling between paramagnetic centers has been detected with an exchange parameter value of −2 J ∼ 1–7 cm −1 . Short intermolecular contacts give rise…
In this work we have investigated the photoluminescence and non-linear optical properties of aqueous synthesized thioglycolic acid (TGA) and 1-thioglycerol (TG) stabilized CdTe nanocrystals (NCs). The photoluminescence intensity of TGA capped NCs was very higher than that for TG capped NCs. XRD and TEM analysis demons…
The solidification path of Al-Cu-Si alloys in the Al-rich corner are investigated. The thermodynamic data needed in the calculation are obtained by direct coupling with the CALPHAD software Thermo-Calc. A paralell experimental investigation is conducted to validate the prediction results. The calculated results show t…
In samples taken from the AE-horizon of podzolic soil in the rhizosphere of spruce and the area external to it, the general chemical parameters and buffering to acid and base were determined by continuous potentiometric titration. It was found that the rhizosphere soil is characterized by significantly (at P = 0.9) hi…
The present paper compares the effects of AC and DC electrical stress on low-κ SiOCH and high-κ ZrO2and Ta2O5back-end dielectrics. A wide panel of stress conditions has been assessed, mixing DC, unipolar/bipolar and relaxation times. The DC-stress being the reference stress condition, no enhancement of the time-to-bre…
The effect of a magnetic field on texture and microstructure development in cold rolled (80%) commercially pure zirconium (Zr701) was investigated. X-ray diffraction and EBSD measurements were utilized for the texture and microstructure characterization. The results revealed that a magnetic field promotes grain growth…
Electrophoretically deposition of Biphasic calcium phosphate on 25 × 10 × 1.2 mm (length, width, and thickness) 316L stainless steel plates using ethanol as dispersing medium; It was achieved on the cathode with constant voltages 20, 30, 50, and 100 V during 20, 30, 60, 90 and 120 seconds, respectively. After depositi…
This research was carried out to study the acoustic properties of natural organic fibres; kenaf and coir fibres using impedance tube method. Kenaf fibre was used as noise absorber filler in an insulation panel while the coir fibre as reinforcement in the perforated composite panel. The perforated panel was made from c…
A new method of synthesizing terephthalate-intercalated layered double hydroxides (LDHs) is reported. The key feature of this method is a reaction of freshly generated hydroxides and terephthalic acid under a hydrothermal condition. Compared with other methods, the terephthalate-intercalated LDHs synthesized using thi…
