Sentence examples for changes of silica from inspiring English sources

It was known based on experimental results that the changes of silica aerogel during 950 1200 °C can be divided into three steps: expansion of primary particles at sample surface (step I), atrophy and pore collapse of primary particles at the surface (step II), and atrophy and pore collapse of primary particles inside the sample (step III).

The differences in transcript levels are expressed as fold change of silica-treated mice compared to saline exposed mice and significant differences were determined by One-way Analysis of Variance with Holm-Sidak all pairwise multiple comparison procedure.

We showed that smaller particles have a greater potential to inhibit CYP3A4 activity than larger particles and that surface modification of silica particles could change their effects on CYP3A4 activity.

Metamorphic processes capable of altering oxygen and hydrogen values result in notable and visible changes to silica, including: (a) recrystallization of silica and the formation of mega quartz (> 35 μm); and, (b) thermal annealing of macro- and micro-morphological silica fabrics.

The low-frequency measurements are resolved in two distinct dielectric Maxwell Wagner Sillars (MWS) processes of different behavior with respect to changes of large-scale silica structures induced by variations of filler fraction and grafting.

Obtained results indicate that the conformational changes of adsorbed polymer chains are responsible for changes in electrokinetic properties of silica particles.

Dissolution of silica changes the ionic strength of interfacial water since some of its dissolution products are known to be charged.

Changes in phase transitions of silica and carbon were studied by using X-ray diffractometry (XRD).

Without invoking any model, this directly indicates that dissolution of silica changes the z-dependent electrostatic potential of the bare silica/water interface to a very similar degree as the addition of approximately 10 mM of NaCl, implying an interfacial concentration of dissolution-released ions of that same order.

At this point, the condensation mechanism of silica changes from electrophilic to electrophobic, so the reduction in transmission here may be attributed to the same reasons as those for pH = 7 but to a lesser extent.

The results obtained show that when the aging temperature changes, the dispersion states and sizes of silica nanoparticles also change and the best results of silica nanoparticles are achieved in the survey area at 60°C (Figure 5c).
