OBJECTIVE The aims of this study were to compare the shear bond strength between orthodontic metal brackets and glazed zirconia using different types of primer before applying resin cement and to determine which primer was more effective. METHODS Zirconia blocks were milled and embedded in acrylic resin and randomly assigned to one of four groups: nonglazed zirconia with sandblasting and zirc...

The development of innovative ceramic tiles looks for materials with improved mechanical and tribological properties as well a higher corrosion resistance (high relative humidity, daily watering, household chemical cleaners). In addition, greater durability leads to lower environmental impact. Along their functionality recyclability, should also provide aesthetic properties. Ceramic can be trea...

  Objective: Adhesion of Lactobacillus acidophilus (L. acidophilus) to dental porcelain surface may lead to gingival inflammation and secondary caries. Surface roughness is among the factors affecting this adhesion. The purpose of this study was to evaluate the effects of four different surface treatment methods on adhesion of L. acidophilus to dental porcelain.   Methods: Sixty specimens (3x10...

Recently, in the Southern necropolis of Apulum, an inkwell with lead-glaze was discovered, which had been deposited as funerary inventory a cremation tomb. Only one other ceramic from pottery centre Micăsasa known Dacia. The shape piece is unique and represents transposition metal-made inkwells. Various technological aspects suggest local production area ancient cities where two workshops glaze...

Abstract Significant self-glazed glass-ceramic was obtained from a natural pozzolan and external glass cullet. Natural with/without cullet fused to melt that quenched in water frits. The dried frits were pulverized (<0.083 mm) then shaped stainless mold. thermal behavior of the glasses shows widening crystallization temperature with incorporation between ∼800 950°C. Sintering powder at 1,050...

This paper presents the design and performance of UAH-78AM, a low-power small Hall effect thruster. The goal this work is to assess feasibility using low-cost 3D printing create functioning thrusters, study how can expand space. thruster features printed discharge channel with embedded propellant distributor. Multiple materials were tested including ABS, ULTEM, glazed ceramic. Thrust measuremen...
