Cement's Basic Molecular Structure Decoded Sep 12, 2009
Scientists have long believed that at the atomic level, cement hydrate (or calcium-silica-hydrate) closely resembles the rare mineral tobermorite, which has an ordered geometry consisting of layers of infinitely long chains of three-armed silica molecules (called silica tetrahedra) interspersed with neat layers of calcium oxide. But the MIT team found that the calcium-silica-hydrate in cement isn't really a crystal ... But a two-dimensional look at a unit of cement hydrate would show layers of... (Science Daily)
Breakdown In Planck's Law Of Heat Transfer Jul 31, 2009
By using the glass (silica) beads, they were able to get separations as small as 10 nanometers (10 billionths of a meter, or one-hundredth the distance achieved before), and are now working on getting even closer spacings. Professor Sir John Pendry of Imperial College London, who has done extensive work in this field, calls the results "very exciting," noting that theorists have long predicted such a breakdown in the formula and the activation of a more powerful mechanism.

Concrete Creep Slowed: Work Paves Way For Lightweight, Vastly More Durable Infrastructure Jun 26, 2009
This led to his publication of a paper in 2007 that said the basic building block of cement paste at the nano-scale calcium-silicate-hydrates, or C-S-H is granular in nature ... They also explain that a third, more dense phase of C-S-H can be induced by carefully manipulating the cement mix with other minerals such as silica fumes, a waste material of the aluminum industry ... "The addition of silica fumes is one known method in use for changing the density of concrete; we now know from the... (Science Daily)
East Asia Minerals Closes Private Placement of $4.641 Million Jun 20, 2009
This initial drill program will comprise 10 holes for a total of 2,000 metres to provide a 3D validation along the full 1,200 metre strike of the Miwah gold-bearing silica zone, exposed along the Miwah ridge. Based on the Company's work Miwah is resolving into two components; a large 1200 metre long, 300 to 400 metre wide, approximately 200 metre thick tabular zone, and vertical feeder zones that are beneath and cut through this.

Origin Of Volcano's Carbon-based Lavas May 7, 2009
The lava expelled from the volcano is highly unusual in that it contains almost no silica and greater than 50 percent carbonate minerals. Typically lavas contain high levels of silica, which increases their melting point to above 900 ... This low silica content gives rise to the extremely fluid lavas, which resembles motor oil when they flow. (Science Daily)
