The density (), refractive index (nD), dielectric constant (s) and relaxation time () of binary mixture of allyl bromide (AB) with n-butanol including those of the pure liquids, were measured over the complete composition range at 283.15 K. The experimental data is used to calculate excess density () E , excess molar…
To improve the oxidation resistance of carbon/carbon (C/C) composites, mullite coating was prepared on the surface of SiC-coated C/C composites by supersonic plasma spraying. Phases and microstructures of mullite coating were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The coating…
Mn-doped GaAs nanowires were grown in the self-catalytic growth mode on the oxidized Si(100) surface by molecular beam epitaxy and characterized by scanning and transmission electron microscopy, Raman scattering, photoluminescence, cathodoluminescence, and electron transport measurements. The transmission electron mic…
The concepts, parameters of assessing the structure, appearance and quality of several types of fancy yarn were presented in in Part I of this paper. Further, the methods, procedures and apparati needed to apply such concepts and parameters were also detailed in Part I. In Part II of this paper, however, those methods…
The biosynthesis of nanoparticles has found increasing attention due to environmentally friendly andcost-effective. In this report, silver nanoparticles (AgNPs) were synthesized using a reduction of aqueous Ag+ ion with the culture supernatants of Aspergillusterreusstrain KC462061 were isolated from the roots of date…
PACS 61.66.Fn The mechanism of BiFeO3 nanoparticle formation from initial compositions obtained by bismuth and iron hydroxides co-precipitation has been studied. The activation temperature of the BiFeO3 nucleation and nanocrystal growth is shown to correlate with that of the nonautonomous phase’s melting. The optimal…
The sand covered area has a more negative potential so it acts as the anode, while adjacent areas have more positive potential acting as the cathode.This is the mechanism that initiates localized corrosion in the sand covered area.Furthermore, when the sand covered area is small as compared to the adjacent exposed are…
The catalytic combustion of carbon black at 350–420°C in the presence of CuMoO 4 has been investigated. The separate catalyst reduction and reoxidation stages make nonadditive contributions to the overall heat of the process. This indicates the formation of catalytically intermediate compounds during the redox reactio…
Nanotechnology involves the creation and manipulation of materials at nanoscale levels to create products that exhibit novel properties. Engineered nanomaterials either metals (like carbon and silver) or metal oxides (like zinc oxide, magnesium oxide, and titanium oxide) induce toxicity and oxidative stress by generat…
Unfilled vulcanized natural rubber exhibits high tensile strength due to its ability to crystallize on straining. The strain-crystallization is a form of reinforcement inherits in natural rubber. This form of reinforcement is attainable when the rubber is strained to high extension. It is not permanent; once the strai…
Developing highly selective probes for subcellular regions such as nucleus and cytoplamic organelles is of great interest for cellular imaging and high content screening analysis for biology and medicine. Cytoplasmic delivery of QDs has been well-understood, while nuclear delivery of QDs has been a challenge due to th…
Abstract Single crystals of novel metastable borate Ba
This paper presents a low-proflle (single layer) circular metamaterial (MTM) mi- crowave absorber structure based on electric fleld driven LC (ELC) resonator. The structure is simulated in HFSS solver giving rise to almost unity absorption (99.92%) at 11.22GHz (X-band). Further a 2£2 array using two difierent variants…
The aim of this paper is to present research work about the mode in which the water sorption-desorption process is influenced by the type of spinning yarns (dry or wet) and by the type of roving treatment (boiling or bleaching) in the case of flax and hemp yarns. The hygroscopic properties of fibres, yarns and woven f…
This paper presents a study on the determination of thermal stability of highly thermally stable polyaniline-dodecylbenzenesulfonic acid (PANI-DBSA) salts using thermogravimetric analysis. This technique was also used to calculate energy of activation (Ea) for the degradation of polymer using Horwitz & Metzger, Coats…
This paper comparatively evaluated the effect of wet processes and heat setting on the shearing properties of treated and untreated griege Indeo™ Poly Lactic Acid (PLA) and Polyethylene Terepthalate (PET) knitted fabrics. The treated samples were subjected to wet processes including scouring, dyeing, alkaline reductio…
Modified chemical bath deposition technique has been implemented for the deposition of silver sulphide thin (CBD) method onto the glass and fluorine doped tin oxide (FTO) coated glass substrate from an aqueous alkaline bath at room temperature (300K). The deposition bath consists of silver nitrate, thiourea and ammoni…
Huge amounts of commercial pharmaceuticals are used worldwide for medical purposes. Paracetamol (PARA) is a medication widely used to reduce fever and pain. It is also combined with other drugs in some prescription pain medications. A current environmental issue is the effects of pharmaceuticals and personal care prod…
Antimicrobial properties of socks containing silver nanoparticles were investigated. Two types of socks were used for testing. The first were linen (100%) socks impregnated with a specimen containing silver nanoparticles. The second type were commercially available cotton (55%) socks containing nanosilver. An antimicr…
Polymerizable ZnS nanoparticles (NPs) were fabricated in N,N′-dimethylacrylamide via a novel facile and effective strategy, and a series of transparent bulk nanocomposites were also prepared based on such polymerizable ZnS NPs. The structure, surface chemistry and distribution of the polymerizable ZnS NPs were studied…
