Effect of 250 MeV107Ag ion irradiation induced columnar defects on the noise properties of the YBCO superconductor in the normal and superconducting state have been investigated. Magnitude of the spectral density of the noise is found to scale inversely with the frequency and exhibit a quadratic dependence on the bias current confirming that the noise arises due to the resistance fluctuations. The magnitude of

The geometries of several Mn clusters in the size range Mn13–Mn23 are studied via the generalized gradient approximation to density functional theory. For the 13- and 19-atom clusters, the icosahedral structures are found to be most stable, while for the 15-atom cluster, the bcc structure is more favoured. The clusters show ferrimagnetic spin configurations.

Lack of resources and increasing environmental pollution has evoked great interest in the research of materials that are friendly to our health and environment. Polymer composites fabricated from natural fibres is currently the most promising area in polymer science. Keeping in view the various advantages of natural fibres, in current series of green composites a study on natural fibre reinforced polymer composites has been made. This paper presents the results of an experimental series designed to assess the possibility of

Biodegradable materials for orthopaedic implants have gained much attention due to their similar properties to natural bone. Magnesium-based alloys are considered the best biodegradable material for bone substitute materials.However, magnesium alloys have very high corrosion rate. Research has been focused to fabricate and to make their composites to control their corrosion rates in human physiological environment and to develop the ability of formingbone-like apatite layer on their surface. In the present study, Mg–Zn–Mn metal alloys were selected for making their composites with hydroxyapatite (HAp) and bio-glasses. HAp was prepared by the co-precipitation method and bio-glasses(45S5P7) were prepared by the melting and quenching method. Samples from metal–ceramic composites were prepared by the powder metallurgy route in various compositions. Furthermore, samples were characterized for their phases,microstructure, corrosion behaviour, mechanical properties and bioactivity. The composites showed bioactivity in simulated body fluid (SBF) solution and their young’s modulus values were obtained near to the human bone. The degradation properties, as studied in SBF solution, revealed Mg-based alloy composites having approximately 10% bio-active glasses and 10% b-tri-calcium phosphate resulted in the reduction of the corrosion rate.
