ObjectivesThis study aimed to evaluate the influence of different shades and brands of resin-based luting agents on the final color of a leucite-reinforced veneering ceramic.

A serial of multi-walled carbon nanotubes (MWCNTs) reinforced geopolymer composites were prepared, and then heated at elevated temperature to fabricate MWCNTs/leucite composites by in situ transformation. Effects of high-temperature treatment on the microstructure evolution and mechanical perfor...

Reduced graphene oxide/cubic-leucite (rGO/cubic-leucite) composites were prepared from reduced graphene oxide/geopolymer (rGO/CsKGP) composites by simultaneous in situ crystallization process and thermal reduction of GO. The effects of both rGO addition and treatment temperature on the microstru...

ObjectiveThis study investigated the influence of the cooling protocol on the mechanical behavior of Y-TZP veneered with porcelain with different compositions. The tested hypotheses were: (1) Y-TZP infrastructures veneered with porcelain containing leucite in its composition presents higher flex...

Ion exchange behavior of analcime-leucite mineral was discussed in this work. Leucite was firstly prepared from analcime in 3.0 mol/L K2CO3 solution, and a liner relationship was fitted between temperature and ion exchange extent. Na+ and K+ distribution in analcime-leucite mineral and Na+-K+ mi...

The Xiaobaishitou W-(Mo) deposit (Central Tianshan Massif, eastern Tianshan, northwestern China) is a skarn-type tungsten-molybdenum deposit associated with a biotite granite intruding the Mesoproterozoic Kawabulag Group. Here we present the results from zircon U-Pb geochronology, whole-rock geo...

Two methods including roasting-water leaching and direct acid leaching, were comparatively studied for the extraction of rubidium from the rubidium-bearing biotite. The leaching behaviors were investigated and optimized conditions were then obtained. For chlorination roasting-water leaching, the...

Electrospinning is the most common technique for fabricating polymer fibers as well as nanoparticles embedded polymer fibers. Silver selenide nanoparticles were synthesized using tri-n-octylphosphine (TOP) as solvent and tri-n-octylphosphine oxide (TOPO) as capping environment. Silver selenide w...

The thermal properties of silver fluoride and silver subfluoride were studied by derivative thermal analysis and by X-ray analysis. From the results, conclusions were drawn on the decomposition mechanism.The thermal behaviour of silver fluoride-alkali halide systems was studied. It was establish...

Ag2F was made by the electrolysis of aqueous silver fluoride solutions. The work function of this metallic compound was estimated from the threshold value of photoelectric emission, 5.5 4 eV, and also from the photoelectron spectroscopical method, 5.4 9 eV.

In this study, linear viscoelastic properties of a chitosan system were investigated in the sol and gel states in terms of glycerophosphate (GP) (CGP) and polymer (CC) concentrations. The chitosan solutions showed a liquid-like behaviour at low β-GP and chitosan content, but deviated from the s...

The Src-family tyrosine kinases (SFKs) are oncogenic enzymes that contribute to the initiation and progression of many types of cancer. In normal cells, SFKs are kept in an inactive state mainly by phosphorylation of a consensus regulatory tyrosine near the C-terminus (Tyr530 in the SFK c-Src). ...

As safe byproducts of drinking water treatment processes, ferric and alum water treatment residuals (FARs) have the potential to be new phosphate (P) immobilization materials. In this study, batch experiments were conducted to investigate and compare the adsorption characteristics of three P spe...

This study shows that how commercial chitosans owing three different molecular weights and high degree of acetylation can be neutralized closed to physiological pH using β-glycerophosphate to produce liquid solution at room temperature and formation of hydrogel upon subsequence heating up to th...

The development of mucoadhesive in situ gelling formulations for intravesical application may improve the therapeutic outcomes of bladder cancer patients. In this work, chitosan/β-glycerophosphate (CHIGP) thermosensitive formulations have been prepared using three different chitosan grades (62,...
