Studies have been made on the corrosion inhibition of aluminium alloy in 2M HCl and HNO3IArachis hypogeae natural oil using gravimetric and potentiodynamic polarization techniques at 25oC. The results revealed that Arachis hypogeae oil in 2M HCl and HNO3-aluminium environment decreased the corrosion rate at various co…
The effects of defatted rice bran (DRB) as a filler for natural rubbervulcanisate on its cure characteristics, mechanical properties and morphology wereinvestigated. The properties of the DRB-filled vulcanisate were also compared with clayfilledand CaCO3-filled vulcanisates. At similar loading level (50 parts per hund…
Cadmium oxide CdO thin films were deposited by thermal evaporation technique at different substrate temperatures on glass substrates. The XRD analysis shows that CdO films are amorphous and transform to polycrystalline with cubic structure when deposited at 448K and annealed at 573K. The direct energy band gap of CdO…
Nowadays natural fibers such as sisal, flax, hemp, jute, bamboo, banana, etc. are widely used for environmental concern on synthetic fibers (such as glass, carbon, ceramic fibers, etc.). In this research work, Sisal Fiber (SF), Banana Empty Fruit Bunch Fiber (BEFBF) and Bamboo Fibers (BF) reinforced with Epoxy matrix…
This paper presents the physical, mechanical and thermal properties of unidirectional jute fiber reinforced polyvinyl chloride (PVC) film composites. Composites (wt % of fiber) of jute fiber reinforced PVC matrix were prepared by compression molding at 160⁰ C. Variable weight ratios of these composites namely 100:0, 9…
The discovery of carbon nanotubes (CNTs) has stimulated intensive research to characterize their structure and to determine their properties. The unique physical, chemical, mechanical, electrical and electronic properties of CNTs make them candidate material for service in electronic devices, energy storage systems an…
We examined supramolecular gelation of propylene carbonate enantiomers with novel chiral aspartame lipids. Different gelation ability and stability were observed based on the combination of gelator and the solvent enantiomers. This work demonstrates that gelator–solvent chirality matching can determine self-assembled…
This paper presents a comparison among classical elasticity, nonlocal elasticity, and modified couple stress theories for free vibration analysis of Timoshenko beams. A study of the influence of rotary inertia and nonlocal parameters on fundamental and higher natural frequencies is carried out. The nonlocal natural fr…
A series of new monocationic iridium(III) complexes [Ir(C^N)(2)(N^N)]PF(6) with "large-surface"α,α'-diimin ligands N^N (dap = 1,12-diazaperylene, dmedap = 2,11-dimethyl-1,12-diazaperylene, dipdap = 2,11-diisopropyl-1,12-diazaperylene) and different cyclometalating ligands C^N (piq = 1-phenylisoquinoline, bzq = benzo[h…
A unique 3D Cu(II) complex based on a molybdate oxide cluster and 5-triazole isophthalic acid was synthesized under hydrothermal condition: {Cu(2)(HL)(2)[Mo(4)O(13)]}·2H(2)O (H(2)L = 5-triazole isophthalic acid) (1). Compound 1 shows a spin canting magnetization behavior, and a definite hysteresis loop with a large co…
Organic isocyanide adsorbed on a noble metal nanostructure can be used as a platform for a volatile organic compound (VOC) sensor operating via surface-enhanced Raman scattering (SERS). This is possible since the NC stretching band of organic isocyanides such as 2,6-dimethylphenylisocyanide (2,6-DMPI) is very suscepti…
In this paper, we have developed a “green” method for the synthesis of metal telluride nanocrystals. In this method, di-n-octylphosphine oxide (DOPO) has been used to disperse Te and form Te–DOPO precursor. This new Te precursor was found to be highly reactive and suitable for the synthesis of metal telluride nanocrys…
A series of heteroaromatic bridging ligands are employed in the synthesis of a family of paramagnetic, heterometallic ring dimers. The extent of spin propagation between the rings via the organic conduit is investigated through micro-SQUID magnetometry and EPR spectroscopy from which conclusions over the mechanism of…
We have investigated correlation of photoluminescence lifetime between zinc oxide (ZnO) nanorods and thiourea‐doped ZnO nanorods (tu: CH 4 N 2 S). Aqueous solutions of ZnO nanorods were deposited on glass substrate by using pneumatic spray pyrolysis technique. The as‐prepared specimens were characterized by X‐ray diff…
As the first example of hydrogelator derived from aminoglycoside antibiotics, the hydrogel of kanamycin indicates that the hydrogel of aminoglycosides preserve the specific interaction with their macromolecular targets (e.g., 16S rRNA), thus illustrating a simple approach to explore and identify possible biological ta…
The corrosion behavior of three commercially available high chromium ferritic steels and one austenitic steel was tested in CO-containing simulated anode gas of a Solid Oxide Fuel Cell. Aim of the study was to evaluate the suitability of selected steels for interconnects in SOFC's with an operating temperature around…
This paper describes a novel approach to templated silicification that could directly generate a tubular structure with a polymer@silica hybrid wall. We developed a new process for the crystallization-driven self-assembled formation of a linear polyethyleneimine (LPEI) template on a substrate surface, which involves t…
We demonstrated an efficient approach for in situ encapsulation of metal nanoparticles (NPs) into nanocages of mesoporous silicas using a co-surfactant as the transportation medium. By using this approach, colloidal Pt and Au NPs were successfully encapsulated into the nanocages of cagelike mesoporous silicas (CMS) an…
The common aggregation of single-wall carbon nanotube (SWCNT) in solution is the critical obstacle to elucidate their unique physico-chemical characteristics and biological properties. Therefore, it is very important to overcome this barrier through manipulation of the weak interaction of small molecules with nanotube…
Sulfato groups capping one or two pairs of adjacent glucose units in methylated cyclodextrin (CD) derivatives have been found to undergo regioselective opening with various nucleophiles; the reported methodology opens the way to the efficient synthesis of tridifferentiated α- and β-cyclodextrins that constitute key st…
