Dielectric anomalies in the incommensurate phase of urea-doped thiourea
2014 Complex dielectric constant has been measured in the modulated phase of a OC(ND2)2-doped SC(ND2)2 single crystal. One can expect that the introduction of doping molecules strongly disturb the chains of hydrogen bonds in such a way that the modulated wave should be affected. In the incommensurate phase a new kind of memory effect is observed and when the variation of temperature is very slo...
متن کاملRigid urea and self-healing thiourea ethanolamine monolayers.
A series of long-tail alkyl ethanolamine analogs containing amide-, urea-, and thiourea moieties was synthesized and the behavior of the corresponding monolayers was assessed on the Langmuir-Pockels trough combined with grazing incidence X-ray diffraction experiments and complemented by computer simulations. All compounds form stable monolayers at the soft air/water interface. The phase behavio...
متن کامل[Purpura after application of a eutectic mixture of local anesthetic].
Actas Dermosifiliogr. 2008;99:493-501 499 Given that most women with chronic discoid lupus are of childbearing age, it is encouraging to encounter a treatment that allows for patients to plan pregnancies more easily. Similarly, we stress that maintenance treatment with lower doses of isotretinoin (20 mg/d) can be useful, allowing lesions to be controlled with reduced systemic side effects. Refe...
متن کاملPurification of naphthalene from eutectic mixture by continuous column crystallization
−To obtain highly purified naphthalene, a column crystallizer was employed and operated in the continuous multistage countercurrent fractional mode. The principles and characteristics of the process are introduced. A large amount of experimental work has been done on the crystallization process in a D=50 mm×1,350 mm column. The effects of operation conditions including the composition of feed, ...
متن کاملPyrolysis of a Binary Mixture of Complex Hydrocarbons: Reaction Modeling
A reaction model was developed for the pyrolysis of binary mixtures of compounds whose reactions can be apportioned into three or fewer parallel chains coupled by chain transfer. A representative application of this model to the pyrolysis of mixtures of the asphaltene model compounds n-pentadecylbenzene (PDB) and n-tridecylcyclohexane (TDC) illustrates its utility. The model, along with its ass...
