متن کاملQuantitative TEM analysis of a hexagonal mesoporous silicate structure.
TEM analysis of mesoporous materials is generally undertaken to give qualitative results. Accurate quantitative analysis is demonstrated in this study. A systematic image analysis of a powder form of a hexagonal mesoporous material known as KIT-6 is conducted using a transmission electron microscope (TEM). Three types of image contrast typically appear in this material (a hexagonal honeycomb st...
متن کاملSilicate emission in Orion ?
We present mid-infrared spectro-imagery and high-resolution spectroscopy of the Orion bar and of a region in the Orion nebula. These observations have been obtained in the Guaranteed Time with the Circular Variable Filters of the ISO camera (CAM-CVF) and with the Short Wavelength Spectrometer (SWS), on board the European Infrared Space Observatory (ISO). Our data shows emission from amorphous s...
متن کاملComputational Aspects of Silicate Networks
In this paper we consider a new interconnection network motivated by molecular structure of a chemical compound SiO4. The different forms of silicates available in nature lead to the introduction of the silicate networks. We investigate various parameters related to this network. We provide an addressing scheme for the nodes of the network and also an algorithm that enables us to draw the silic...
متن کاملViscosity models for silicate melts
Rheology of silicates (melts or super cooled as glasses) is one of the most important fields to mankind, as geological activity largely influences life. In this paper, unifying empirical models for the Non-Newtonian shear viscosity and the extensional viscosity are proposed. The models have only one parameter, the zero shear viscosity (the Newtonian plateau), and are valid for a vide range of c...
