Characterization of aged elastic explosives based upon pentrite and polyurethane binder by differential scanning calorimetry and infrared spectrophotometry / Ispitivanje starenih elastičnih eksploziva na bazi pentrita i poliuretanskog veziva diferencijalnom skenirajućom kalorimetrijom i infracrvenom spektrofotometrijom
(Vojnotehnički institut, Beograd, 2001)
Elastic explosives, based upon two types of binder antioxidants, were artificially aged at 60 and 80°C, and in cycles at -30 and +60°, during four months. The aging effects on the samples of elastic explosives were examined ...
Second harmonic generation at the quantum-interference induced transparency in semiconductor quantum wells: The influence of permanent dipole moments
(IEEE-Inst Electrical Electronics Engineers Inc, Piscataway, 2001)
The influence of permanent dipole moments of quantized states on intersubband second harmonic generation based on quantum-interference induced transparency in semiconductor quantum wells is explored using the harmonic ...
Mathematical modeling of gel drying with supercritical carbon dioxide / Matematičko modelovanje sušenja gela natkritičnim ugljen dioksidom
(Association of the Chemical Engineers of Serbia, 2001)
The most complex step in the production of aerogels is the supercritical drying step, and it is therefore important to study its dynamics using mathematical models. Alumina/silica aerogel was obtained using a one step ...
