Wickremarachchi, P.A.S.R.; Spells, S.J.; de Silva, D.S.M. (Journal of Physical Chemistry, 2007)

Raman spectroscopy has been used to investigate the monoclinic crystal f rotator f melt phase transitions in n-C34H70, for both real-time heating and cooling runs. Changes in band intensity and frequency in the CH2 bending, ...

Effect of pretreatments on extending the shelf life of minimally processed “Ela Batu” (Solanum surattense)

Dharmabandu, P.T.S.; de Silva, D.S.M.; Wimalasena, S.; Wijesinghe, W.A.J.P.; Sarananda, S. (Tropical Agricultural Research and Extension, 2007)

Due to the cumbersome nature of the cleaning process and high time consumption for the preparation, most Sri Lankan housewives are reluctant to prepare Solunum surattense (Sinh. Elabatu) as a vegetable for their diet. If ...

The effects of self-poisoning on crystal morphology and growth rates

Ungar, G.; Putra, E.G.R.; de Silva, D.S.M.; Shcherbina, M.A. (Advances in Polymer Science, 2005)

Recent extensive experimental work and the limited theoretical studies of the phenomenon of self-poisoning of the crystal growth face are reviewed. The effect arises from incorrect but nearly stable stem attachments which ...

Events at the growth face as revealed by concentration dependence of crystallization rate of long alkanes

Ungar, G.; Putra, E.G.R.; de Silva, D.S.M. (American Chemical Society, 2004)

It is by now well known that monodisoerse n-alkanes, long enough to exhibit chain folding, show a minimum in crystal growth rate with increasing supercooling ΔT. The minimum occurs near the transition from extended-chain ...

Perpendicular and tilted chains in lamellar crystals

de Silva, D.S.M.; Zeng, X.B.; Ungar, G.; Spells, S.J. (Journal of Macromolecular Science-Physics, 2003)

Chain tilt and surface disorder were investigated in end-deuterated long n-alkane C12D25C192H384C12HD24 crystallized from solution and in n-alkane C162H326 crystallized from melt. Small-angle X-ray scattering and infrared ...

de Silva, D.S.M.; Zeng, X.; Ungar, G.; Spells, S.J. (Macromolecules, 2002)

Small-angle X-ray scattering (SAXS) and infrared spectroscopy (IR) are employed in a study of chain tilt and disorder in solution-crystallized long alkanes C198H398 and C12D25C192H384C12HD24 in extended and once-folded ...

Dilution wave and negative-order crystallization kinetics of chain molecules

Ungar, G.; Mandal, P.K.; Higgs, P.G.; de Silva, D.S.M.; Boda, E.; Chen, C.M. (Physical Review Letters, 2000)

We show that the crystal growth rate of a very long-chain n-alkane C198H398 from solution can decrease with increasing supersaturation and follow strongly negative order kinetics. The experimental behavior can be well ...
