Sentences with phrase «vaterite in»

This makes it even more remarkable that we have found vaterite in such large quantities on the surface of plant leaves.»

Not exact matches

The solubilities (Fig. 3) show a discrete differentiation of the ACC phases in between pH 9.50 and 9.75, whereas distinct amounts of vaterite are precipitated when the ion product is still dominated by ACC I (pH = 9.40)(fig.

WAXS (wide angle x-ray scattering) analysis of the crystalline particles finally formed at ambient conditions shows that pure calcite (the stable polymorph of calcium carbonate) forms at pH - values corresponding to high binding strength in clusters and that predominantly vaterite (the least stable polymorph) and traces of calcite form at pH - values corresponding to low binding strength in clusters (fig.

The laboratory's Microscopy Core Facility Manager, Dr Raymond Wightman, said vaterite was of interest to the pharmaceutical industry: «Biochemists are working to synthetically manufacture vaterite as it has potential for use in drug delivery, but it is not easy to make.

In this case, the microscope not only identified signatures corresponding to calcium carbonate as forming the crust, but was also able to differentiate between the calcite and vaterite forms when it was present as a mixture while still attached to the leaf surface.»

Other potential uses of vaterite include improving the cements used in orthopaedic surgery and as an industrial application improving the quality of papers for inkjet printing by reducing the lateral spread of ink.

But in some cases, droplet - like particles of uncrystallized material known as amorphous calcium carbonate, or ACC, formed first and then transformed into either aragonite or vaterite.

All of the common crystal forms, including calcite (found in limestone), aragonite (found in mother - of - pearl), and vaterite (found in gallstones), crystallized from solution, often at the same time.

Multiple forms often nucleated in a single experiment — at least one calcite crystal formed on top of an aragonite crystal while vaterite crystals grew nearby.

Her master's research focused on the causes and consequences of vaterite deformations in the sagittal otoliths of farmed salmonids, and was primarily conducted at the Institute of Marine Research field station in Matre, Norway.
