| 1 | Effect of neat and reinforced polyacrylonitrile nanofibers incorporation on interlaminar fracture toughness of carbon/epoxy composite显示文摘This paper presents an experimental investigation on fracture behavior of epoxy resin-carbon fibers composites interleaved with both neat polyacrylonitrile(PAN)nanofibers and Al_2O_3-PAN nanofibers.In particular,the paper focuses on the effect of adding Al_2O_3 nanopartiles in PAN nanofibers,which were incorporated in unidirectional(UD)laminates.The effectiveness of adding a thin film made of Al_2O_3-PAN on the fracture behavior of the carbon fiber reinforced polymer(CFRP)has been addressed by comparing the energy release rates,obtained by testing double cantilever beam(DCB)samples under mode I loading condition.A general improvement in interlaminar fracture energy of the CFRP is observed when the both neat PAN nanofibers and Al_2O_3-PAN nanofibers are interleaved.However,higher interlaminar strength has been observed for the samples with a thin film of Al_2O_3-PAN nanofibers,suggesting a better stress distribution and stress transformation from resin-rich area to reinforcement phase of hybrid composites. | S.M.J.Razavi R.Esmaeely Neisiany S.Nouri Khorasani S.Ramakrishna F.Berto | 2018 | Theoretical & Applied Mechanics Letters2018，8，2： | 3 |
| 2 | Synthesis of novel isoxazolyl bis-thiazolo[3,2-a]pyrimidines显示文摘A new synthetic strategy for the synthesis of novel 3-(3-(3-methyl-4-nitroisoxazol-5-yl)-2-phenyl-1-(5,7-diaryl-7H-thiazolo[3,2-a]pyrimidin-3-yl)propyl)-5,7-diaryl-7H-thiazolo[3,2-a] pyrimidines(7a-i) analogues is described.Reaction of 3-(2(3-methyl-4-nitroisoxazole-5-yl)-1-phenylethyl)pentane-2,4-dione(3) with two moles of thiourea in presence of iodine and CuO afforded 4-(1-(2-aminothiazol-4-yl)-3-(3-methyl-4-nitroisoxazol-5-yl)-2-aryl propyl-thiazol-2-amine(5).Compound 5 on reaction with two moles of chalcone(6) furnished novel 3-(3-(3-methyl-4-nitroisoxazol-5-yl)-2-phenyl-1-(5,7-diaryl-7H-thiazolo[3,2a]pyrimidin-3-yl)propyl)-5,7-diaryl-7H-thiazolo[3,2-a] pyrimidines(7a-i). | E.Rajanarendar S.Ramakrishna K.Rama Murthy | 2012 | Chinese Chemical Letters2012，23，8： | 3 |
| 3 | A facile and convenient synthesis of novel imidazo[1,2-b] isoxazoles and their Mannich bases as potential biodynamic agents显示文摘A series of novel imidazo[1,2-b]isoxazoles 3 and their Mannich bases 4–6 were synthesized via convenient reactions. The reaction of 3-aminoisoxazole 1 with substituted phenacyl bromides 2 in dry ethanol afforded the corresponding 6-methyl-3-aryl imidazo[1,2-b]isoxazoles 3 in good yields.Compounds 3 on treatment with 37% formaline and secondary amines furnished the corresponding novel Mannich bases viz., 6-methyl-3-aryl-2-(morpholine/pyrrolidin-1-yl/piperidin-1-yl)-methyl-imidazo[1,2-b]isoxazoles 4–6. | E.Rajanarendar K.Thirupathaiah S.Ramakrishna D.Nagaraju | 2015 | Chinese Chemical Letters2015，26，12： | 2 |
