MC/ilM Analvsi s of air for the n resenee of TNT is conducted by drawing the air from one point in the room through two sintered glass bubbling tubes setup in series and contg ca 150 ml acetone, at a rate of 0.5 1/sec, for a period about 1 hr. After a partial concn of acetonlc soln by evapn at temp below 82°, the voi of concentrate is measured and 1 ml is withdrawn for test. 

Ethylbenzene (RH) oxidation was studied at 120°C in glass bubbling-type reactor in the presence of Ni(II)(acac)2 and additives of (L = N-methylpyrrolidone-2 (MP), HMPA MSt (M=Na, Li)) and PhOH. The selectivity Speh and RH conversion degree C of ethylbenzene into PEH oxidation were determined using the formulas Speh = [PEH] / A[RH]-100% and... 

Table 41 shows comparison of matrixes between epoxy resin and wax as matrix. The glass bubbles apparently improved the strength of the wax matrix while lowering its density, whereas the highest-strength epoxy suffered the greatest strength loss. 

Dicaperl HP-110, HP-210, HP-510, HP-710, HP-910 two series of these hollow glass bubbles are produced standard -10 series and high performance - 20 series which has one of the two proprietary coatings used to increase adhesion (the density is in the range of 0.18-0.25 g/cm which indicates that these are light weight bubbles)...

The terms fining and refining refer to the removal of gaseous inclusions, or bubbles, from the melt. Although the presence of bubbles in a glass sample is not necessarily detrimental for many scientific studies, bubbles are definitely undesirable in most commercial glasses. Bubbles in commercial products are almost always considered flaws and result in rejection of the product. These gas-filled inclusions may occur as very small spheres (< 0.4 mm diameter), which are frequently called seed...
