We prepared numbers of GeAsSe glasses and investigated their thermal stability and optical properties in order to search the best glasses with relatively high glass transition temperature Tg, strong structural stability, low optical loss and high optical nonlinearity. Through our systematical measurements, we concluded that the glasses with a mean coordination number around 2.45-2.5 are the bes...

An anaglyph image allows the perception of depth when observed through colored glasses such as the familiar red/blue glasses. Although the method is very old, the techniques used to generate anaglyph images are very empirical. This paper describes a projection method to generate anaglyph stereoscopic images using the spectral absorption curves of the glasses, the spectral density functions of t...

Metallic glasses remain an elusive material type, due to the lack of analytical formulae or empirical models for their prediction. However, recent improvements in experimental methods have provided high-density alloy data, making it possible to apply machine learning techniques for prediction of metallic glasses. In this paper, we consider a variety of machine learning algorithms for predicting...

Submit Manuscript | http://medcraveonline.com only osteoconductivity but also osteoinductivity, has attracted much interests in the field of bone tissue engineering but not only. Indeed, the typical silicate bioactive glasses demonstrated to bond to bone more efficiently than any other synthetic materials [1]. However, it was rapidly found that the highly disrupted silica network of bioactive g...

We review recent numerical progress in the study of finite dimensional strongly disordered magnetic systems like spin glasses and random field systems. In particular we report in some details results for the critical properties and the non-equilibrium dynamics of Ising spin glasses. Furthermore we present an overview over recent investigations on the random field Ising model and finally of quan...

Glasses of the system x (SnO) (50-x)PbO : 50V2O5 were prepared by melt quenching in the range x = 0 mole% to 15 mole%. Measurements are reported for dc electrical conductivity for the above compositions in the temperature range 300K-500K. The experimental results are analyzed with reference to various theoretical models proposed for dc electrical conduction in amorphous semiconductors. The anal...

Introduction: Glasses on Mars, formed by impact melting and volcanism, likely make up a significant fraction of the regolith because they accumulate over time and there have been few processes operating in the last ~3.5 Ga to destroy them [1]. These glasses have exciting astrobiological implications because they can host microbial colonies and preserve biosignatures [2-5]; they may have also se...

A nonlinear and nonadditive composition-dependent change of the ionic conductivity in mixed glass-former (MGF) glasses when one glass former, such as PS(5/2), is replaced by a second glass former, such as GeS2, at constant alkali modifier concentrations, such as Na2S, is known as the mixed glass-former effect (MGFE). Alkali ion conducting glasses are of particular interest for use as solid elec...

Driven by the increasing economic burden associated with bone injury and disease, biomaterial development for bone repair represents the most active research area in the field of tissue engineering. This article provides an update on recent advances in the development of bioactive biomaterials for bone regeneration. Special attention is paid to the recent developments of sintered Na-containing ...

The effect of chemical composition on the Raman spectra of a series of natural calcalkaline silicate glasses has been quantified by performing electron microprobe analyses and obtaining Raman spectra on glassy filaments (~450 µm) derived from a magma mingling experiment. The results provide a robust compositionally-dependent database for the Raman spectra of natural silicate glasses along the c...
