In this paper, the chemical functionalization of carboxylated multi-walled carbon nanotubes (MWNT-COOH) by 1,2-phenylenediamine, have been investigated. MWNT-benzimidazole is obtained through MWNT-Amide reaction with POCl3 after 72h, which is confirmed by FT-IR, SEM, TGA, and elemental analysis. These functionalizations have been chosen due to NH2 and NHCO active sites in MWNT-Amide for future...
فرآیند ماشینکاری به روش تخلیه الکتریکی( edm)، یکی از فرآیندهای نوین ماشینکاری است که کاربردهای متنوعی در ساخت و تولید محصولات میکرومتری دارد. رشد و توسعه نانوتکنولوژی و نیاز به بهره گیری از روشهای جدید موجب شده است که جذبه زیادی برای استفاده از فرآیند edm در ساخت و تولید محصولات نانومتری ایجاد شود. فرآیند nano-edm یک فرآیند ماشینکاری حرارتی است که در آن از انرژی حرارتی حاصل از جرقه الکتریکی برا...

two new samples of poly(amide-imide)/nanocomposites containing bicyclo segment and dibenzalaceton moiety in the main chain were synthesized by a solution intercalation technique. poly(amide-imide) (pai) 8 as a source of polymer matrix was synthesized by the direct polycondensation reaction of n,n´-bis(4-carboxyphenyl)bicyclo[2,2,2]oct-7-ene-2,3,5,6-tetracarboxylic diimide 3 with 2,6-bis(4-amino...
some amide derivatives have been synthesized by the reaction of corresponding nitriles with potassium tert-butoxide as a nucleophilic oxygen source under ultrasonic irradiation. this new methodology provides good to excellent yields in short reaction times (15-90 min) at room temperature.
Previous studies have revealed that the glucoincretin hormone glucagon-like peptide-1 (GLP-1)(7-36)amide is metabolized by dipeptidyl peptidase-IV (DPP-IV) and neutral endopeptidase 24.11 (NEP) to yield GLP-1(9-36)amide and GLP-1(28-36)amide, respectively, as the principal metabolites. Contrary to the previous notion that GLP-1(7-36)amide metabolites are pharmacologically inactive, recent studi...
