Scission yields are determined by stress relaxation measurements during irradiation of specimens. Permanent and temporary chain scissions are measured by this technique in contrast to gel measurements, which provide data only on permanent scissions. 

Sol-Gel Measurements. The relative rates of crosslinking and scission may be estimated from soluble-fraction measurements. For an initial random molecular weight distribution and random chain scission, extrapolating a curve of S + S vs. 1/D, where S = sol fraction and D —...

It was shown that liposomes, due to their structure, have a retarding effect on the incorporated drug release. In early studies, Knepp et al. reported that progesterone release from agarose gel was faster than from liposomes embedded in the gel [29]. This retarding release behavior from liposomes was further confirmed by a lower drug transport rate as compared to the gel measured across hairless mouse skin [30], Another study by Foldvari et al. [8] examined the... 

Fig 9.29 illustrates Zn determination in a Zn binding protein in a selected protein spot after separation of the proteins of an S layer used as biomolecular template, as described above, by 2D gel measured by LA-ICP-SFMS at medium mass resolution (m/Am = 4000). ° The Zn ion intensity in the protein spot (compared with the background signal in the gel blank) was measured at three different positions in the selected spot. Using LA-ICP-SFMS, the highest Zn intensity was found in the middle of the protein spot investigated. Additional measurements by MALDI-MS on Zn containing protein spot in 2D gel can be useful to identify the structure of the protein. ...

Analytical isoelectric focusing was carried out using a Pharmacia-LKB Multiphor II unit with a 4.0-6.5 PAG plate. After running the gel, it was sliced in 1 cm pieces and the slices were incubated overnight at 30°C with 25.0 mM DKP in 25.0 mM potassium phosphate, pH 8.0, containing 1.25 mM EGTA. Samples were analyzed by TLC for the production of a-AP which was then correlated with the pH in the gel, measured by a flat electrode.

The birefringence of the LC gel observed above the clearing temperature of the non-reactive LC is attributed to the thermally stable network that remains oriented at elevated temperatures. However, this birefringence of the gels measured above the clearing temperature is higher than what is expected from the network alone, indicating that part of the non-reactive LC molecules... 

The CIE Lab color scale was used to measure Hunter L (Lightness), Hunter +a (redness), Hunter -a (greenness). Hunter +b (yellowness), and Hunter -b" " (blueness) values. Color values of gels were measured using a Chroma Meter (Model CR-310, Minolta Corporation, Ramsey, NJ). The instrument was standardized for surimi gel measurement by using a Minolta calibration plate (No. 18133009 = 94.5, 0.3160, 0.3330) and a... 

In 1935 Brunauer and Emmett [121] carried out the first successful attempt to determine - by means of isotherm adsorption of six different gases - the surface area of an iron synthetic ammonia catalyst. Later [122], in 1937, these authors determined the surface area of two different silica gels measuring adsorption isotherms of seven different gases.. In the above mentioned works the surface area was determined by extrapolating the middle linear sections of experimental isotherms to zero pressure in order to obtain the amount of gas required to cover the adsorbent surface with a monomolecular layer. On condition that the monomolecular layer was in a close-packed stage, the surface area was then evaluated from the monolayer adsorbed amount. Brunauer and Emmett [121,122] also proposed to determine the monolayer adsorption amount from the so-called point B of the experimental isotherm. It was assumed that this point corresponds to the inflection point and can be obtained from the beginning of the linear section of adsorption isotherms.
