The stability of organogels differs based on the organogelator concentration, storage temperature, and solvent type. Organogel post-crystallization annealing was monitored at 5°C, 15°C, 20°C or 30°C for up to 1 month. Gels, stored at 5°C, had highly immobilized oil, as judged from large T 2 relaxation peaks at 50–70ms determined by pulsed nuclear magnetic resonance (pNMR) and visual observations...
The measurement of urinary creatinine is important in many situations, but perhaps most importantly when measuring the urinary content of substances other than creatinine. Because urine flow changes unpredictably during the day, but total creatinine output is generally constant, many investigators normalize their results to creatinine content (i.e. mg chromium/mg creatinine). Because the widespread...
