Non-graphitizing carbon beads were heat-treated to 1300" -1900" under 5 kbar. Whereas the original beads carbonized at looo" graphitize abruptly at 1500" -16CV, the pre-heated ones demand higher temperature for their graphitization. The 1500"-pre-heated and 2100"-pre-heated graphitized above 17M1",

A review of the recent work on acceleration of graphitization under high pressure
A glass-like carbon of homogeneous structure cured up to ItXWC (GC-IO) was heat-treated under pressure of 5 kbar. The heat ~eatment was performed in two different cell a~angements; in one a~angement quasi-hydrostatic pressure was dominant and in the other there were many contact points between the c
Techniques for the immobilization of bovine carbonic anhydrase (BCA) on porous silica beads and graphite are presented. Surface coverage on porous silica beads was found to be 1.5 x 10(-5) mmol BCA/m(2), and on graphite it was 1.7 x 10(-3) mmol BCA/m(2) nominal surface area. Greater than 97% (silica
