The analysis of solvation in ionic liquids and organic solvents using the Abraham linear free energy relationship

The contentions made in an earlier paper [J Chem Technol Biotechnol 80 : 133–137 (2005)] that the coefficients of the Abraham solvation equation do not provide meaningful information on the molecular properties of ionic liquid solvents is refuted. The objections noted in the earlier paper disappear when the solvation equation model is correctly applied to the experimental data. It is further shown that the coefficients of the Abraham solvation equations can be used to characterize ionic liquids and can be used to select solvents for the solubility of gaseous solutes.

Synthesis and polymerization of anthracene‐based itaconimides

Two new anthracene‐based itaconimides, ie N‐(1‐ and 2‐anthryl) itaconimides, were synthesized by the reaction of aromatic amines with itaconic anhydride, followed by itaconamic acid imidization. The same reaction failed in the case of anthracene‐ring substitution at the position 9′. Radical and thermal polymerization of N‐(1‐ and 2‐anthryl) itaconimides led to polymers with anthracene pendant groups. No self‐polymerization by Diels–Alder cycloaddition of the itaconic function (dienophile) and anthracene nucleus (diene) was observed, as is the case for N‐(anthryl) maleimides and citraconimides.

大面积高质量金刚石自支撑膜热导率的影响因素研究

通过Raman、XRD、SEM分析方法分别对大面积高质量金刚石自支撑膜的质量、晶体结构、晶粒尺寸进行研究,分析它们对金刚石自支撑膜热导率的影响.研究结果表明,金刚石自支撑膜的质量对热导率的影响较大,质量越好,热导率越接近于天然金刚石的热导率;并且金刚石自支撑膜中晶体[220]取向度越高,热导率越高.形核面晶粒尺寸越大,晶粒间的晶界就减少,有利于提高金刚石自支撑膜的热导率.
