The arc-plasma vitrification of a hospital wastes containing metals and inorganic oxides yields to a leachresistant glassy or vitreous slag, which can be environmentally safe for landfill disposal or could be transformed in glass-ceramic tiles with physical and mechanical properties similar to those showed by marketable products for building applications. Standard methods have been used for tes...

In the glass industry, nucleation agents are broadly used to obtain homogeneously dispersed and nanograined crystals during heat treatment leading to glass ceramics. In this paper, the role of zirconia and titania used as nucleation agents in a lithium alumosilicate glass is studied on the nanoscale using cutting edge analytical and imaging techniques performed in the transmission electronmicro...

Abstract Different types of glass-ceramic composites are being researched around the world as potential matrices for nuclear waste conditioning. To demonstrate their long-term durability and build a safety case geological disposal, accelerated irradiation tests simulating He accumulation effects recoil nucleus damage needed. study behaviour in these materials, particularly, zirconolite-based gl...

BACKGROUND The dietary intake of harmful elements, particularly lead and cadmium constitutes a health threat and essential measures should be undertaken to reduce consumer exposure. The latest risk assessments by the European Food Safety Authority (EFSA) and Joint FAO/WHO Expert Committee on Food Additives (JECFA) have indicated that the Provisional Tolerable Weekly Intake (PTWI) for lead and c...

Bi2O3-based glasses are very attractive from the viewpoints of low-melting, high refractive index, and crystallization, and the research on their glasses and glass-ceramics is at the frontiers of glass science and technology. Non-linear optical Bi2ZnB2O7 crystal lines with a high orientation were patterned in 3Sm2O3-30.3Bi2O3-33.3ZnO-33.3B2O3 glass by using a laser-induced crystallization techn...
