Exceptionally strong polyolefin nanocomposites are synthesized by in-situ polymerization using soluble metallocene/methylaluminoxane (MAO) as catalysts in a two-step process. First, the soluble metallocene/MAO or other single site catalysts are absorbed on the surface of the nanofillers. Then by addition of ethene or propene, a polyolefin film is formed, covering the nanoparticles, layered silicates, or fibers. The resulting polyethylene and polypropylene nanocomposites are characterized by better physical and chemical properties such as stiffness, gas barrier properties, degradation temperatures, and crystallization rates. They show better mechanical properties than materials produced by mechanical blending. The thickness of the polyolefin can be controlled by the pressure of ethene or propene and by the polymerization time. Carbon fibers and carbon nanotubes are covered with isotactic or syndiotactic polypropylene. Because of the hydrophobic character of the carbon surface, the polymer is drawn on the fiber. This leads to a reinforced combined polymer with special properties. The crystallization temperature is 10 °C higher and therefore the crystallization rate up to 20 times faster than that of pure syndiotactic polypropylene. The form stability increases by 100% if 3 wt-% of carbon nanotubes are incorporated.

利用荧光原位杂交(FISH)和克隆文库构建技术,研究了厌氧污泥床反应器处理含酚废水时所收获的颗粒的微生物群落结构。研究发现,互营杆菌(Syntrophorhabdaceae)和隐杆厌氧菌(Cryptanaerobacter)的克隆是苯酚降解的主要原因。为了准确地对隐杆厌氧菌的克隆进行分类归属,需要利用近全长的16S核糖体RNA(rRNA)基因序列进行进化分析。设计了三种寡核苷酸探针用于检测以下三个分类群:互营杆菌、隐杆厌氧菌和互养菌。对厌氧颗粒薄片的FISH 分析显示细菌和古菌呈随机分布。然而,互营杆菌、隐杆厌氧菌和互养菌分布明确。在颗粒细胞的外层发现了隐杆厌氧菌和互养菌,两者关系密切,而互营杆菌则位于颗粒细胞的深层。细菌之间的代谢联系和对底物的亲和力很可能是造成这种特殊分布的原因。研究人员观察到颗粒污泥中苯酚的降解主要通过以下方式进行:首先,隐杆厌氧菌将苯酚转化为苯甲酸盐,然后被互养菌降解为乙酸盐。苯酚的这种互饲降解发生在颗粒表面附近,此处苯酚浓度较高。在苯酚浓度较低的颗粒深部,互营杆菌将苯酚降解为乙酸盐。结果表明,互营杆菌不太可能产生苯甲酸盐,并将其作为中间产物来喂养邻近的生物,这一点与以往研究所提出的理论相矛盾。
