Eye/face protection
Face shield and safety glasses Use equipment for eye protection tested and approved under
appropriate government standards such as NIOSH (US) or EN 166(EU).
Skin protection
Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique
(without touching glove's outer surface) to avoid skin contact with this product. Dispose of
contaminated gloves after use in accordance with applicable laws and good laboratory practices.
Wash and dry hands.
The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and
the standard EN 374 derived from it.
Body Protection
Complete suit protecting against chemicals, The type of protective equipment must be selected

  Liquid Crystalline Epoxy Thermosets

  摘要：

  Rigid rod epoxy compounds can be cured in liquid crystalline structure. The so obtained networks exhibit better mechanical properties with respect to the isotropic ones. The mesogenic character of the epoxy compounds appears more crucial than the molecular geometry of the curing agent in developing liquid crystallinity. The curing temperature plays an important role in affecting the state of order of the thermosets.

  摘要：

  摘要 在此，我们报告了第一个使用球磨进行镍 (0) 介导的 Yamamoto 偶联反应的固态方案。多种芳基卤化物在双(环辛二烯)镍(0)[Ni(cod)2]和4,4'-二叔丁基-2,2'-联吡啶存在下在固态机械化学条件下有效反应，以高产率提供相应的联芳基。考虑到不需要潜在有害的高沸点有机溶剂，本研究为传统的基于溶液的山本偶联提供了一种更方便、更环保、更可持续的替代方案。还描述了固态山本偶联聚合和催化变体的开发。
