The quartz dissolution in HF under rather mild conditions (at room temperature on a shaker-table) has the advantage to leave difficult-to-dissolve minerals (e.g., tourmaline, zircon, rutile, sillimanite, kyanite, chromite, corundum), not separated by other physical methods before, as residue.

The discovery of x-rays by Roentgen in 1895 is often taken as the starting point of modern physics, as x-rays, besides causing a revolution in medicine, allowed the first experimental determination of the atomic structure of matter, i.e. of the spatial arrangement of atoms in molecules and solids.
Introduction. Vararia is separated from Corticium by the presence of dichophyses which form the bulk of the context and hymenial tissues. Dichophyses of most species are small dendriform structures arising from a simple stem. Each is composed of a cluster of branches, in turn once or several times branched, often dichotomously, branchlets terminating in acuminate, long or short straight or ...
The lowermost sand layer shows no evidence for deposition by turbulent flow, being devoid of erosional or tractional structures with the exception of rare grooves or tool marks, and has a high matrix content (see 4.2 section). Instead, the sandier part of the bed is interpreted to represent the deposit of a high‐concentration flow where yield ...

However, most Antarctic research would probably not be adversely impacted by resource activities. Un-derstanding of oceanography, marine ecology, meteorology, and cold-region engineering could
The local molecular structure of Co(II) surface complexes sorbed to two pure mineral substrates, quartz (α-SiO 2) and rutile (TiO 2), was examined with X-ray absorption spectroscopy (XAS) and extended X-ray absorption fine structure (EXAFS) analysis.Absorption spectra were collected for samples equilibrated with Co solutions under- and over-saturated with respect to solid Co-hydroxide phases ...
Rutile also lends its name to the rutile mineral group. The only other gem-quality member of this group that gets faceted (rarely) is cassiterite. As needle inclusions, rutile crystals occur in a wide variety of gem materials, such as quartz and agate (sagenite). Rutilated quartz pieces can make stunning jewelry stones as well as display specimens.
lattice becomes a metal with a rutile struc-ture when heated above the transition tem-perature T c = 340 K. The controversial nature of the low-temperature insulating phase, as well as substantial uncertainty over the roles of structural motion and electronic correlations in driving the phase transition, have fueled an enduring debate over the

Rutile is a common accessory mineral in high-temperature and high-pressure metamorphic rocks and in igneous rocks.. Thermodynamically, rutile is the most stable polymorph of TiO 2 at all temperatures, exhibiting lower total free energy than metastable phases of anatase or brookite. Consequently, the transformation of the metastable TiO 2 polymorphs to rutile is irreversible.
