The influence of building material structure on radon
Radon (222 Rn) is the most familiar radioactive gas, produced in 226 Ra alpha decay, and has been recognized as the leading cause of lung cancer in the world after smoking (WHO 2009).The main source of radon in closed areas is the soil under the building, while the contribution of used building materials is usually very low.Crystals 2020, 10, 160 2 of 16 1. Introduction The long-term clinical success of dental ceramics is influenced directly by several factors. Some of these factors include the crystal-based microstructure of the ceramic material, the fabrication processThe E on the Surface Roughness and Microhardness of

Ultra-high heating rate effects on the sintering of ceramic
Abstract. Heating rate plays a major role in the ceramic sintering process, especially in many new advanced sintering techniques. In this study, the effects of ultra-high heating rate up to 1200°C/s have been investigated on various ceramic nanoparticles by in situ transmission electron microscopy (TEM) heating experiments to monitor the Background Incompatible coefficient of thermal expansion (CTE) is supposed to be a reason for chipping of ceramic veneered zirconia. This study evaluates the effect of veneering ceramic at varied(PDF) Role of coefficient of thermal expansion on bond

Cemented versus screw‐retained zirconia‐based
1. INTRODUCTION. Dental implants for the rehabilitation of single‐tooth gaps are a valuable therapeutic option resulting in high long‐term survival and success rates (Donati et al., 2016; Jemt, 2016; Jung et al., 2012; Zembic et al., 2015).Titanium abutments restored with porcelain fused to metal crowns are considered to be the gold standard Crystals 2020, 10, 160 3 of 17 2.

Effect of different endodontic access preparations on
Results. The lithium disilicate glass-ceramic onlays had lower fracture resistance values than the resin nanoceramic onlays in both the traditional and conservative endodontic access cavity groups (P<.05).The fracture resistance of the 2 materials for onlays with endodontic access was significantly lower than that for the intact restorations Advanced structural ceramics are playing a key role in addressing these challenges in vehicle propulsion systems and will be a major source of inspiration for the next generation of autonomous vehicles. Humankind's aerospace aspirations are placing unprecedented demands on vehicle propulsion systems. Advanced structural ceramics Advanced structural ceramics in aerospace propulsion.

Corrosion Resistance of Ceramics Based on SiC under
Metrics. We study the possibility of improvement of the corrosion resistance of ceramics based on silicon carbide (SiC) under the conditions of high-temperature steam corresponding to the standard operating conditions of fuel shells in WWER-1000 (water-moderated water-cooled) power reactors. We formed and sintered The influence of the local matrix environment on Er 3+ luminescence properties is a key factor in the development of optical temperature sensors. The high sensitivity of Er 3+ luminescence to the local structure, where the optically active ions reside, was analyzed along with the ligands type and bond character within the framework of the Role of the host matrix on the thermal sensitivity of Er

A systematic review of the survival and complication rates of
2.2 Focused question. The focused question of the present review was: “In partially edentulous patients with implant-supported single crowns (SCs) do veneered zirconia and/or monolithic zirconia SCs exhibit differences in prosthetic outcomes compared with metal-ceramic implant-supported SCs?”Results. Within the lithium disilicate CAD groups, intervention did not result in any significant differences in color change (P>.05).Within the zirconia groups, a 15-year clinical simulation revealed significantly higher ΔE values than a simulated 5-year exposure (P=.017).Increased simulated cycles showed significantly higher R a values for all groups.Effect of brushing and thermocycling on the shade and
