Vycor is the brand name of Corning's high-silica, high-temperature glass. It provides very high thermal shock resistance. Vycor is approximately 96% silica and 4% boron trioxide , but unlike pure fused silica , it can be readily manufactured in a variety of shapes.
For commercially available porous glasses, the terms porous VYCOR-Glass (PVG) and Controlled Pore Glass (CPG) are used. The pore structure is formed by a syndetic channel system and has a specific surface from 10 to 300 m 2 /g. Porous glasses can be generated by an acidic extraction of phase separated alkaliborosilica glasses, or by a sol-gel ...
For most of its history, Grace's main business was cargo shipping, operating the Grace Line. To move cargo from Peru to North America and Europe, including guano and sugar, and noticing the need for other goods to be traded, William Grace founded a shipping division.

Nafion membranes are commonly categorized in terms of their EW and thickness. [ 2 ] [ 5 ] For example, Nafion 117 indicates an extrusion-cast membrane with 1100 g/mol EW and 0.007 inches (7 thou) in thickness. [ 5 ]
Vycor is also the name of a company that sold (or still does - I'm not sure) the DP Umbrella software package. DP Umbrella was (or still is) a mainstream help desk and asset management application used by companies such as toy-giant Mattel, inc. Perhaps a disambiguation page is in order.

Ion channels are also classified according to their subcellular localization. The plasma membrane accounts for around 2% of the total membrane in the cell, whereas intracellular organelles contain 98% of the cell's membrane. The major intracellular compartments are endoplasmic reticulum, Golgi apparatus, and mitochondria. On the basis of ...
The cytosol is the site of multiple cell processes. Examples of these processes include signal transduction from the cell membrane to sites within the cell, such as the cell nucleus, [57] or organelles. [58] This compartment is also the site of many of the processes of cytokinesis, after the breakdown of the nuclear membrane in mitosis. [59]
