As dentistry continues to evolve, new technologies and materials are continually being offered to the dental profession. Throughout the years restorative trends and techniques have come and gone. Some material developments have transformed the face of esthetic dentistry, while other initial concepts have already phased out and disappeared. Today, all-ceramic restorations continue to grow in the...

Pulp and paper waste water is one of the major sources of industrial water pollution. This study tested the suitability of ceramic tubular membrane technology as an alternative to conventional waste water treatment in the pulp and paper industry. In this context, in series batch and semi-batch membrane processes comprising microfiltration, ultrafiltration and nanofiltration, ceramic membranes w...

A complete package [ensemble, complex] of physical and chemical investigations was conducted: x-ray phase analysis, differential thermal analysis waste generated in the production vanadium. It established that these wastes, which contain 17.39% Mn2O3 their composition, are a promising raw material for wall ceramics with volumetric-staiing. The effect heat treatment at 200, 500, 600, 700°C on co...

Two vessels from different sites of the Iranian Plateau, dating to the late 4th or early 3rd millennium BCE are presented aspalaeotechnological case studies. In the fractures of the vessels’ walls, interfaces left by added clay parts (enhanced inthe two illustrations) are quite recognizable. It is proposed that in both cases potters, in order to construct the bases, usedto make bowls comparable...

J. Zych, J. Kolczyk, Ł. Jamrozowicz, AGH University of Science and Technology, Faculty of Foundry Engineering, Kraków, Poland Multi-layer ceramic moulds are built of slurry and a refractory material forming their matrices. From the moment when the European Union introduced regulations concerning the environment protection requiring substitution of alcoholic binders by aqueous binders, several d...

Low Temperature Co-fired Ceramic (LTCC) technology is a multi-layer ceramic process that can be used to fabricate low cost, high performance RF and microwave components. It is an extremely versatile technology that can be used to realise a wide range of components from simple passive filter structures and packages to complex sub-system assemblies containing discrete SMT (Surface Mount Technolog...

Diarrheal disease and environmental enteropathy are serious public health concerns in low-income countries. In an effort to reduce enteric infection, researchers at the University of Virginia developed a new point-of-use (POU) water treatment technology composed of silver-impregnated porous ceramic media. The ceramic is placed in a 15 L plastic container of water in the evening and the water is...
