In 2007 Tbilisis Forumi became the most popular internet-forum in Georgia, having nearly thousand registered users logged in every day. [2] As of 4 May 2018, the website claims to have 158,220 users and 49,640,102 posts.
The hexagonal (d = 4.29 g/cm 3) form of germanium dioxide is more soluble than the rutile (d = 6.27 g/cm 3) form and dissolves to form germanic acid, H 4 GeO 4, or Ge(OH) 4. [6] GeO 2 is only slightly soluble in acid but dissolves more readily in alkali to give germanates . [ 6 ]
Solidified lava flow in Hawaii Sedimentary layers in Badlands National Park, South Dakota Metamorphic rock, Nunavut, Canada. Geology (from Ancient Greek γῆ (gê) ' earth ' and λoγία () ' study of, discourse ') [1] [2] is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which they are composed, and the processes by which they change over ...
Richard Chorley (1927–2002), a key contributor to the quantitative revolution and the use of systems theory in geography. Sir Nicholas Shackleton (1937–2006), who demonstrated that oscillations in climate over the past few million years could be correlated with variations in the orbital and positional relationship between the Earth and the Sun.
[1] [2] Margaret "Meg" Molleston, joined the company in 2006 and leads the management of GeoSouthern's assets.

A zeolite reported in 2005 [14] has large pores – 18.6 × 26.2 Å interconnected by channels defined by 30-membered rings (the naturally occurring zeolite faujasite with channels defined by 12-membered rings [15]). Zeolites with frameworks containing silicon and germanium (silicogermanates), aluminium and germanium (aluminogermanates) and ...
Germanium(IV) iodide reacts with tetraalkyl tin at 250 °C to form R 2 SnI 2 and R 2 GeI 2 (R= Et, Bu, Ph). [5] It reacts with germanium and sulfur at high temperatures to produce red GeSI 2 and orange Ge 2 S 3 I 2. [6] It reacts with diiron nonacarbonyl in an ionic liquid ([BMIm]Cl/AlCl 3) at 130 °C to obtain Ge 12 [Fe(CO) 3] 8 I 4. [7]
