Three-dimensional enriched finite elements are used to compute mixed-mode stress intensity factors (SIFs) for three-dimensional cracks in elastic functionally graded materials (FGMs) that are subject to general mixed-mode loading. The method, which advantageously does not require special mesh configuration/modifications and post-processing of finite element results, is an enhancement of previou...

Mesoporous transition metal nitrides are interesting materials for energy conversion and storage applications due to their conductivity and durability. We present ordered mixed titanium-niobium (8:2, 1:1) nitrides with gyroidal network structures synthesized from triblock terpolymer structure-directed mixed oxides. The materials retain both macroscopic integrity and mesoscale ordering despite h...

The primary tooth pulpectomy is a common clinical procedure. The choice of filling material is important to the success rate, but antibacterial properties of such materials against organisms known to inhabit infected primary root canals have not been well documented. This study compared the antibacterial effectiveness of 10 materials: 1. Calcium hydroxide mixed with camphorated parachlorophenol...

This paper shows that for 24 out of 25 solid waste materials, recycling saves more energy than is generated by incinerating mixed solid waste in an energy-from-waste facility. Recycling conserves energy that would otherwise be expended extracting virgin raw materials from the natural environment and transforming them to produce goods that can also be manufactured from recycled waste materials. ...

In order to solve the problem of performance mixed alkane phase change energy storage materials, this paper proposes modelling research thermodynamic model based on new materials. paper, binary system is studied, influence transition temperature, enthalpy and its composition explored, solid-liquid diagram drawn. We used different models predict temperature in melting process alkanes, which were...

backgrounds the degree of microleakage is one of the main criteria in evaluating the restorative materials such as glass ionomer (gi) restoratives, which are available in two forms: loose powder and liquid form to be hand-mixed or pre-proportioned in a capsule to be mixed mechanically. objectives this study was conducted to compare the microleakage of encapsulated gi restoratives with their han...

Mixed-anion compounds, in which multiple anions such as O2?, N3?, and H? are contained the same compound, have recently attracted attention. Because mixed-anion compounds a unique crystal structure with coordinated to cations, materials fundamentally new innovative functions expected be developed for various chemistry physics applications, including catalysts, batteries, superconductors. In thi...

Using density-functional theory calculations, we study the stability and electronic properties of single layers of mixed transition metal dichalcogenides (TMDs), such as MoS2xSe2(1-x), which can be referred to as two-dimensional (2D) random alloys. We demonstrate that mixed MoS2/MoSe2/MoTe2 compounds are thermodynamically stable at room temperature, so that such materials can be manufactured us...
