Transmission electron microscopy and related analytical techniques have been widely used to study the microstructure of different materials. However, few research works have been performed in the field of glasses, possibly due to the electron-beam irradiation damage. In this paper, we have developed a method based on electron energy loss spectroscopy (EELS) data acquisition and analyses, which ...
A comprehensive study was performed of various types aluminum-containing raw materials and their effect on glass formation during smelting borosilicate glasses for type-E fiber. It is shown that use non-metallurgical alumina, as compared with metallurgical disthene-sillimanite concentrate, kaolin, a savings energy resources processes from 2.64 to 16.30% obtains.
The aim of this research is to examine the radiation shielding properties 5B2O3-40SiO2-(55-x)Al2O3-xBaO (BSABa-x) glass systems, which are containing barium and aluminum oxide added borosilicate glasses, with varying from 25 34 weight fractions. Shielding parameters, such as linear attenuation coefficients (LAC), mass (MAC), mean free path (MFP), effective atomic number (Zeff), electron density...
UNLABELLED Herein, for the first time, we combined poly-l-lactic acid (PLLA) with a strontium borosilicate bioactive glass (BBG-Sr) using electrospinning to fabricate a composite bioactive PLLA membrane loaded with 10% (w/w) of BBG-Sr glass particles (PLLA-BBG-Sr). The composites were characterised by scanning electron microscopy (SEM) and microcomputer tomography (μ-CT), and the results showed...
