| 5. | Hexadecyl hydrogen maleate ( hhm ) is a new kind of analyzer crystal for soft x - ray spectroscopy , with a large 2d spacing of 58 . 58a . hhm is hoped to give a better growth habit than octadecyl hydrogen maleate ( ohm ) , because of its shorter chain length and narrower 2d spacing . in this paper , a large hhm single crystal of dimensions 60mm x 40mm x 3mm was obtained in the benzene solution by lowing the solution temperature 马来酸氢十六酯( hhm )是一种新型的软x ?射线分光晶体,晶面间距2d等于58 . 58a ,与ohm (马来酸氢十八酯)属同一系列分光晶体,碳链的缩短、晶面间距的减小有望给出比ohm更好的生长和结晶习性。 |
| 6. | Polybenzoxazine / vermiculite hybrid nanocomposites were prepared from two kinds of polybenzoxazine precursors and two kinds of organically modified - vermiculite minerals and expanded - vermiculite which were consisted of vermiculite , hydrobiotite and phlogopite . after treatment of vermiculite minerals by hexadecyl trimethylam monium bromide ( ctab ) , the d001 of vermiculite layers of vermiculite mineral increased from 1 . 43nm to 2 . 67nm and developed a d002 = 1 . 34nm 本文分析了蛭石精矿和膨胀蛭石的组成和结构,用十六烷基三甲基溴化铵( ctab )进行了有机化处理,再通过熔融或溶液混合插层苯并嗯嗪树脂( ben )制备了ben插层蛭石纳米复合材料,并采用蒙脱土进行了对照实验。 |
