Interconversion between different stoichiometric forms of a three-component crystal via liquid-assisted grinding.
A second polymorphic form of a 1 : 2 : 3 pamoate : DABCO : water salt has been obtained by liquid-assisted grinding, and it is shown that interconversion between this salt and a salt with 1 : 1 : 2 stoichiometry is facile via liquid-assisted grinding with additional amounts of pamoic acid (to generate the 1 : 1 : 2 salt) or DABCO (to generate the 1 : 2 : 3 salt).
متن کاملControllable selective exfoliation of high-quality graphene nanosheets and nanodots by ionic liquid assisted grinding.
Bulk quantities of graphene nanosheets and nanodots have been selectively fabricated by mechanical grinding exfoliation of natural graphite in a small quantity of ionic liquids. The resulting graphene sheets and dots are solvent free with low levels of naturally absorbed oxygen, inherited from the starting graphite. The sheets are only two to five layers thick. The graphene nanodots have diamet...
متن کاملChiral Crystal Growth under Grinding
To study the establishment of homochirality observed in the crystal growth experiment of chiral molecules from a solution under grinding, we extend the lattice gas model of crystal growth as follows. A lattice site can be occupied by a chiral molecule in R or S form, or can be empty. Molecules form homoclusters by nearest neighbor bonds. They change their chirality if they are isolated monomers...
متن کاملTemperature Tunability of Dielectric/ Liquid Crystal / Dielectric Photonic Crystal Structures
Recently, photonic crystals doped with liquid crystal (LC) material havegained much research interest. In this article new ternary one-dimensional photoniccrystal introduced and studied. The liquid crystal layer of 5CB and 5PCH is sandwichedby two dielectric layers. For the first time, we use four structures SiO2/UCF35/CaF2,SiO2/5CB/CaF2, NFK51/UCF35/NPSK53 and NFK51/5CB/NPSK53. The effect ofte...
متن کاملchemical recycling of polycarbonate waste using conventional heating and microwave assisted method
پلی کربنات یکی از پلاستیکهای مهمی است که به صورت گسترده در تولید لوحهای فشرده، قطعات رایانه، مواد ساختمانی و غیره مورد استفاده قرار می گیرد. این پلیمر بصورت عمده از تراکم مونومر بیس فنولa (bpa) و کربنیل کلرید یا دی متیل کربنات ها بدست می آید. در سالهای اخیر بازیافت شیمیایی پلی کربنات بیشتر مورد توجه بوده است. بازیافت شیمیایی پلی کربنات برای بدست آوردن مواد اولیه آن با روشهای متفاوتی مانند تجزی...
