Abstract Barium titanium borate glasses doped with ytterbium ions were fabricated via standard melt quenching technique. The building structure of the glass matrices ascendant ratios studied using Raman and FTIR spectroscopies. UV–Vis–NIR optical absorption spectra investigated used to calculate bandgaps, Urbach energies, refractive indices, metallization criterion, basicity, dispersion paramet...

Melt generation and migration are important processes for the evolution of the Earth’s interior and impact the global convection of the mantle. While they have been the subject of numerous investigations, the typical time and lengthscales of melt transport are vastly different from global mantle convection, which determines where melt is generated. This makes it difficult to study mantle convec...

Melt ponds, a common feature on Arctic sea ice, absorb most of the incoming solar radiation and have a large effect on the melting rate of sea ice, which significantly influences climate change. Therefore, it is very important to monitor melt ponds in order to better understand the sea ice-climate interaction. In this study, melt pond retrieval models were developed using the TerraSAR-X dual-po...

The expansion in application of the selective laser melting (SLM) process for fabrication of new alloy materials continues. However, to date, there has been no investigation of the effect of this process on the final microstructure of ‘melt sensitive’ powder alloys such as mechanically alloyed oxide dispersion strengthened (ODS) FeCrAl. In this study commercial PM2000 powder, a ferritic ODS all...

In the present study Rizatriptan benzoate, which is the bitter drug requires taste, masking. βCyclodextrin is used in taste masking, which improves the patient compliance and also increases the rate of dissolution. Solid dispersion of drug and βCyclodextrin were prepared which was optimised in 1: 8 ratios, which gave satisfactory results for taste masking. This was then characterised using Diff...

A ceramic material suitable for packaging of large scale integrated circuit is produced by the process of forming a mixture of a powdered glass ceramic material which is a glassy precursor to cordierite ceramic material, formed by the steps which are as follows: a. Mix tetragonal phase material selected from the group consisting of zirconia or hafnia powder con taining a stabilizing oxide compo...

Figure2 While there are limitless applications for these materials, we are interested in radiation shielding and radiation resistant materials for use in the space industry. Initially, we focused on optically transparent single wall nanotoube (SWNT) polymer composites (2-5). Three different in situ polymerization/sonication methods, heat, light and gamma radiation, were used to produce poly (me...

Compared with pristine polymers, bionanocomposites derived from biopolymers and inorganic nanoparticles have significantly improved electrical/magnetic properties, mechanical properties, thermal stability, gas barrier properties, and fire retardance. In this study, poly(lactic acid) (PLA) nanocomposites were prepared by in situ melt polycondensation of L-lactic acid with different loading ratio...
