The effect of different molar strengths of Britton Robinson buffer (pH 4.2) over the range (0.0075-0.1 M) on the separation of the formed complex was investigated.
A gradual decrease in the previously mentioned parameters was observed when the molar strength was either lower than 0.015 M or higher than 0.05 M. Furthermore, alteration of the peak symmetry of the resultant complex was remarkably observed at the higher molar strength.
The position and depth of the impacted tooth, particularly the mandibular third molar, compromises the strength of this bone predisposing it to fractures at the angle.
This work evaluates the significance of the four common mix design parameters, namely Si/Al (molar ratio), water/solids (mass ratio), Al/Na (molar ratio) and H2O/Na2O (molar ratio), in determining compressive strength of metakaolin-based geopolymers through experiments and statistical analyses.
A uniform relative dielectric of 78.4 and an ionic strength of 0.15 Molar were used in calculations of charge interactions.
The effect sintering additives comprising AlN and Re2O3 (Re = Sc, Lu, Yb, Er and Y) in a 2 3 molar ratio on the high-temperature strength of liquid phase-sintered and subsequently annealed SiC ceramics was investigated.
Aim of the present study was to evaluate fracture strength of endodontically treated molars with different preparations/restorations after thermomechanical loading in vitro.
The effect on the compressive strength of Na2O/SiO2 and SiO2/Al2O3 molar ratios and type of curing was evaluated.
However, since the addition of fluoride in solution modifies the ionic strength of the medium, the molar concentration of KNO3 was adjusted consequently when fluoride was added in order to maintain a constant ionic strength throughout our experiments.
At first, in order to evaluate the effect of NaOH solution concentration on compressive strength of stabilized sand, various molar concentrations of 2, 4, 6 and 8 M were employed.
