Policy Exchange, a centre-right think-tank, looked at the A-levels offered by successful applicants to a group of 27 very selective universities—some ancient, some modern—and concluded that, despite the fact that all subjects are notionally equal, in reality admissions tutors think more of some than of others.

Some morphological and anatomical observations on both male and bisexual flowers were made in different developmental stages. The right stage when the selective abortion happened in male flower was ascertained preliminarily. The result was that the ovule in ovary of male flower abored when the megasporocyte was not formed in nucellar tissue.

Due to the increasingly deep concerns about the cytotoxicity of stannous octoate, which is the most widely used catalyst for synthesizing polyesters derived from lactides (L-LA, D, L-LA, GA) via ring opening polymerization, a lot of new metal complexes of relatively low toxicity including Schiff base–Al complexes, Red-Al were developed and used to initiate the living, stereo-specific, and/or stereo-selective ROP of lactides.

由于合成聚乳酸类生物医用降解材料的最常用的催化剂辛酸亚锡 Sn2的细胞毒性问题已在世界范围内引起日益深切的关注，近年来国内外学者已研究开发出许多性能优异的低毒、非锡金属络合物催化剂（如：位阻西佛碱-Al 络合物， Red-Al 等）用于催化交酯类单体的活性、立构专一性及立构选择性聚合反应。
