The use of Chrome-Manganese austenitic stainless steel (Cr–Mn ASS) has tremendously increased in past few years in applications like home accessories, office appliances, light poles, etc and it is serving as an alternative to 300 series. But, the study related to sensitization behavior of these steels is scanty. There…
The inhibition of iron (Fe, 99.98%) corrosion after its immersion for 60 minutes in freely aerated 3.5% sodium chloride (NaCl) solutions by low concentrations of 3-amino-1,2,4-triazole-5-thiol (ATAT) and 1,1'-thiocarbonyldiimidazole (TCDI) was reported. The experimental tests in this work were open circuit potential (…
Chemical constituents of purified sample of Ficus platyphylla gum was investigated using GCMS technique. The results obtained indicated the presence of methoxy-phenyl-oxime (0.79 %), 1-methoxyethyl benzoate (4 %), palmitic acid (7.58 %), oleic acid (10.15 %), octadecanoic acid (6.2 %), 1-phenanthrenecarboxylic acid (p…
Abstract. This is a chapter surveying the current state of our understanding of tilings with infinite local complexity. It is intended to appear in the volume Directions in Aperiodic Order, D. Lenz, J. Kellendonk, and J. Savienen, eds, Birkhauser. 1.

A comprehensive study of structural modifications of gamma irradiated polymers in the dose range of 101 Gy to 106 Gy, was conducted using FT-IR technique. The results were varied in nature, proving that all polymers do not undergo similar type of destruction under similar irradiation conditions. The IR spectrum of pol…
Biosensor technology has recently been witnessing momentous progress, thanks to the advent of nanoscience and especially with the realization of the great role that noble metal nanostructures can play as basic platforms. Nanosilver exhibits superior optical properties as compared to other noble metals and thus has att…
Ubiquitin and ubiquitin chains are recognized by a large and growing family of receptor proteins. NMR spectroscopy provides a powerful means to evaluate whether and how a protein binds to ubiquitin. It can be used to measure binding affinities, to map interaction surfaces, and to solve the three-dimensional structure…
High dielectric constant, low porosity and nano-dimension particle of single layer magnesium oxide, MgO and multilayer ZnO/MgO were synthesized at different MgO solution molar concentration by the simple chemical solution technique. The MgO molar concentration was found to alter the properties of both single and multi…
The application of anionic stabilizers is of great importance in the synthesis of supported metal nanoparticles with small and uniform size and high dispersion. Herein, we extensively studied the influence of four congeneric anionic stabilizers on the morphology of carbon-supported Pd nanoparticles, and evaluated the…
Polytetrafluoroethylene (PTFE) fiber was grafted with acrylic acid to impart the carboxyl groups onto the fiber surface, which were used to coordinate with both transition metal ions Fe(III) and Cu(II) and a rare metal ion Ce(III) to prepare the metal grafted PTFE fiber complexes as the novel heterogeneous Fenton cata…
We provide the scientific basis for the use of Calotropis procera for treating skin and wound infections in traditional medicine. The aqueous extract of stem-bark of C. procera exhibited more pronounced potent antimicrobial activity. Calo-protein was purified and identified from the most-active aqueous extracts of C.…
We report a facile hydrothermal route for the synthesis of PbS–PbTe core–shell heterostructured nanorods. The phase ratio of PbS to PbTe can be tuned by introducing different molar ratios of PbS to the Te precursor (molar ratio of PbS to Te precursor, R). The as-prepared samples were characterized by the X-ray diffrac…
The influence of phosphor particle size on phosphor concentration in white LEDs and on the optical performance of the resulting device was investigated. Phosphor photoluminescent properties show that increasing particle sizes result in higher emission intensities. White LEDs were fabricated based on YAG phosphor of na…
Carbon nanotubes have attracted significant attentions as novel one-dimensional nanomaterials due to their unique structures and properties. Aggregate properties of Carbon Nanotubes (CNTs) such as high surface area, length or surface chemistry are further tailored to enhance their potential application in nanomedicine…
We report the use of hydrodynamic cavitation as a novel, bottom-up method for continuous creation of foams comprising of air micro-bubbles in aqueous systems containing surface active ingredients, like proteins or particles. The hydrodynamic cavitation was created using a converging–diverging nozzle. The air bubble si…
A gram-positive bacterium that accumulated poly(3-hydroxybutyric) acid (PHB) was isolated from petrol bunk soil. From its morphological and physiological properties and the nucleotide sequence (about 1.5 kb) of its 16S rDNA, it was identified as Microbacterium barkeri DSM 20145. Based on the available literature, this…
The effect of gamma radiation on corrosion of copper under anoxic conditions in pure water has been studied experimentally. Copper samples submerged in water were exposed to dose rates of 0.37 or 0.77 kGy/h. Reference samples were used throughout. The copper surfaces have been examined using the techniques of SEM-EDS,…
Role of surface grain refinement in AZ31 Mg alloy by shot peening on surface energy, biomineralization and degradation behavior
Multiferroic (MF) materials with simultaneous magnetic and electric long range order and occasionally, mutual magnetoelectric (ME) coupling, have recently attracted considerable interest. The small linear ME effect has been shown to control spintronic devices very efficiently, e.g. via the classic ME antiferromagnet C…
