شہادتوں کے علم
شہادتوں کے علم جب بلند ہو جائیں
تو پھر جہان میں رسوا یزید ہوتے ہیں
عظیم باپ کی بیٹی بتا گئی شوکت
حسینؑ والے ہمیشہ شہید ہوتے ہیں
وطن کے ہر غریب کو جگا کے آپ سو گئی
شعور جب طلوع ہوا تو خود غروب ہو گئی
غریب قوم کے لیے وہ باپ کی سفیر تھی
نظیر جس کی نہ ملے وہ اتنی بے نظیر تھی
وفاق کی امنگ تھی عوام ہی کے سنگ تھی
کنیز کربلا کی بس یزیدیت سے جنگ تھی
بہا کے لے گئی ہر ستم کو اپنی موج سے
وہ کربلائے وقت میں ڈری نہیں ہے فوج سے
وہ آمروںکی گردنوں پہ نقش پا جما گئی
وہ بھٹو بھٹو کر کے سب کو بھٹو ہی بنا گئی
سنو لحد کی گود میں وہ صاحب مراد ہے
وہ کل بھی زندہ باد تھی وہ اب بھی زندہ باد ہے
سلام شہید رانی
Abdul Haq, India’s most popular researcher and literary figure, got retirement from the University of Delhi as dean of the Department of Urdu. For the very first time in India, he selected Iqbaliat as his doctorate topic. His books on Iqbaliat highlighted various unexplored topics and personalities. He presented and preached Iqbal’s thoughts and quotations exactly the way Iqbal wanted them to be presented. His articles on Iqbal always received great appreciation from all the literary circles and conferences in which he presented them. As a profound lover and having an understanding of Iqbal’s poetry, he gave new dimensions to his poetry, previously unknown to the world. Furthermore, as a researcher, he discussed numerous scholars who claimed to have an understanding of Iqbal’s poetry and analyzed their work critically. The current study is an acknowledgement of Professor Abdul Haq’s endeavors in the field of education, literature and his services for Iqbaliat. Moreover, the present study encompasses his written publications on the topic of Iqbaliat.
Phthalonitrile resins are high temperature thermosetting polymers, which are considered ideals materials for marine, aerospace, and electronic applications. The synthesis of phthalonitrile monomers with self-catalyzing nature and with large processing window – defined as the temperature between the melting temperature of the monomer and the gelation temperature of the polymer network–, are gaining much more importance because of ease in processability and high thermal stability. In the present study, some novel phthalonitrile resins were synthesized using ortho- linked phthalonitrile monomers and self-catalyzing phthalonitrile monomers with different linkages such as: ether, imide-ether, and amide-ether between the reactive ends. All the synthesized monomers were characterized by spectroscopic techniques such as FT-IR, 1 H-NMR and 13 C-NMR. FT-IR indicated absorption peaks around 1522 and 1355 cm -1 and around 1010 cm -1 indicated the formation of triazine and phthalocynine rings (heterocyclic rings formed as a result polymerization) respectively after post curing. The thermal analyses were carried using DSC, TGA, DMA, and Rheometery. DSC and rheometric studies showed that the monomers with ortho linkages have low melting point and high crosslinking temperature. In self-catalyzed monomers, the monomers having amino group at ortho position or 1,2-linked (ortho) monomers have broad processing window. The complex viscosity (η*) was very low (<1 Pa.s) in between melting and the crosslinking temperature, which is highly suitable for resin transfer molding, resin infusion molding, and filament winding. TGA studies revealed that the resin synthesized from the monomer with heterocyclic ring shows high thermal stability and residual mass (char yield). The thermal stability of the polymer having ether or imide-ether linkages are nearly the same but more than the polymer having amide-ether linkage, indicating the effect of crosslinking density and structural changes. DMA measurements showed that storage muduli (E'') and glass transition temperature (Tg) enhance with the increase of curing temperature. These meaurements also indicated that the polymers having imide-ether and amide-ether linkages have higher storage moduli than the polymers have only ether linkages.
