Mesophase Pitch-based Carbon Fiber and Its Composites: Preparation and Characterization

exploring motivation and english test preparation strategies of iranian pre-university candidates during and at the end of test preparation period for konkur examination

the current study aimed at investigating the relationship between motivation and test preparation strategies (tpss) used by iranian pre-university students in their preparation period for the university entrance exam (uee). due to the importance of uee in iran, this study also attempted to show its impact on these two important variables. to this end, 100 pre-university students in an iranian p...

simulation and design of electronic processing circuit for restaurants e-procurement system

the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...

Preparation of mesophase pitch by aromatics-rich distillate of naphthenic vacuum gas oil

Two aromatics-rich distillates R1 and R2 with different properties from naphthenic base vacuum gas oil were used for preparing mesophase pitch through high-pressure thermal treatment. 1H-NMR, FT-IR and VPO were employed to characterize the structural parameters of the raw materials. The products' optical texture and molecular structure were analyzed by polarized light optical microscopy, 1H-NMR...

Preparation Of Mesophase From Anthracene Oil

The transformation of anthracene oil into pitch is a feasible procedure for obtaining pitches with binder and impregnating characteristics. Moreover, their high aromaticity, total absence of solid particles and good fluidity make anthracene oil-based pitches interesting precursors for graphitizable carbon materials (e.g., carbon fibres, synthetic graphites). To prepare this kind of material the...
