An NMR study of solvent interactions in paramagnetic system

An Nmr Study on Solvent - Polymer Interactions

Approximately 80 percent of all synthetic polymers used are cross-linked polymers, unfortunately the characterization of cross-linked polymers has not kept up with their use. This study tries to help in the characterization of cross-linked polymer systems. More specifically the interactions of cross-linked polymer systems with solvents will be probed. Nuclear Magnetic Resonance (NMR) spectromet...

بررسی دلایل عملکرد متفاوت سوالات آزمون درک مطلب به زبان خارجی تاریخچه ی تحقیق درباره ی منابع عملکرد مختلف سوالات (دیف) در آزمون درک مطلب پر است از مجموعه ای از متغیرهای فرضیه ای که چند مورد از مهمترین آنها عبارتند از: جنسیت، آشنایی با موضوع متن، علاقه به موضوع یا محتوای متن، حدس زدن، و عوامل بافت اجتماعی (پی 2004؛ زومبو و گلین 2005). مطالعه حاضر با استناد به فلسفه ی انکارپذیری پوپر عوامل ذکر...

Paramagnetic NMR Investigation of Dendrimer-Based Host-Guest Interactions

In this study, the host-guest behavior of poly(amidoamine) (PAMAM) dendrimers bearing amine, hydroxyl, or carboxylate surface functionalities were investigated by paramagnetic NMR studies. 2,2,6,6-Tetramethylpiperidinyloxy (TEMPO) derivatives were used as paramagnetic guest molecules. The results showed that TEMPO-COOH significantly broaden the ¹H NMR peaks of amine- and hydroxyl-terminated PAM...
