标题:脂肪酸酰胺的电喷雾电离和碰撞诱导解离质谱
摘要:伯脂肪酸酰胺是一组生物活性脂质,已与多种生物过程(如睡眠调节和单胺能系统调节)联系在一起.随着这些分子的新颖形式的不断发现,将更加侧重于选择性的痕量检测.目前,尚无公开的实验确定pfam的碰撞诱导解离.将选定的一组pfam标准(碳链长度为12至22)直接注入电喷雾电离源四极杆飞行时间质谱仪中.使用[m + H] +峰以阳性模式监测所有标准物.使用mass Hunter定性分析软件来计算产物离子的经验公式.所有pfam的损耗均为14 M /z表示酰基链,而单不饱和基团显示对应于h 2 O和nh 3的中性损失.所得光谱用于提出碎裂机理.同位素标记的pfam用于验证所提出的机制.饱和和不饱和标准液的模式非常不同,可以轻松区分.该确定将允许快速,定性地识别pfam.此外,它将提供一种方法开发工具,用于在多反应监测模式下进行分析时选择独特的产物离子.

摘要:The invention relates to a method for obtaining polyamide or copolyamide particles which are spheroidal and whose average diameter is between 40 and 150 μm, preferably between 60 and 100 μm. Said method consists of introducing a mineral charge, preferably silica, having an average diameter of 1-30 μm into the reaction mixture. The invention also relates to a polyamide or copolyester amide powder and to the use thereof in order to manufacture coatings, ink compositions, paint compositions, cosmetic compositions, pharmaceutical compositions, alloys with metal powders or metal oxide powders and parts by agglomerating said powder by laser sintering, IR radiation or UV radiation.

标题 :Higher fullerenes useful as radical scavengers
发明人：KRONHOLM DAVID F; HUMMELEN JAN C; SIEVAL ALEXANDER B
权利人:NANO C INC
摘要:Chemically functionalized fullerenes are useful in various applications as radical scavengers. These chemically functionalized fullerenes offer the advantages of preservation of the high innate radical scavenging efficiency of the fullerene cage and ease of synthesis of fullerene derivatives of desirably altered chemical and physical properties and single isomers. Further, they are based on a common intermediate chemistry and intermediates can be easily functionalized and tailored to various requirements.

权利人:LEE CHOON WOO; ELEVANCE RENEWABLE SCIENCES
摘要:This invention relates generally to olefin metathesis, and more particularly relates to the ring-opening, ring insertion cross-metathesis of cyclic olefins with internal olefins such as seed oils and the like. In one embodiment, a method is provided for carrying out a catalytic ring-opening cross-metathesis reaction, comprising contacting at least one olefinic substrate with at least one cyclic olefin as a cross metathesis partner, in the presence of a ruthenium alkylidene olefin metathesis catalyst under conditions effective to allow ring insertion cross metathesis whereby the cyclic olefin is simultaneously opened and inserted into the olefinic substrate. The invention has utility in the fields of catalysis, organic synthesis, and industrial chemistry.
