آوارگی

آوارگی
تمہیں فرصت ہو تو۔۔۔ذرا دیکھو۔۔۔!
لہریں تڑپتی رہتی ہیں
بادبانوں سے گلے ملتے ہوئے، ہوائیں چلتی رہتی ہیں
جواز صلیب کی ارغوانی خانقاہوں کا۔۔۔!
میں کیسے گمشدہ لفظوں کی امید بن کر طواف کرتا ہوں
کہیں تاثیر قیس بن کر۔۔۔!
کہیں عزیز حسن بن کر۔۔۔!
رات کے پچھلے پہر آہوانِ راز کی طرح
دلفریب خوشبو میں قلندرانہ رقص کرتا رہتا ہوں۔۔۔!
سعد ستاروں کی وصل زاد آواز کی طرح!
دشت و بیابان میں۔۔۔فرشتوں کی حویلی میں!
منتظر سبز بانہوں میں!
سرخ نصاب کا یقیں بن کر رہتا ہوں
پورب کی لالی سے۔۔۔پچھم کی لالی تک۔۔۔!
فقیروں میں اپنی جاگیر تقسیم کرتے ہوئے!

بھید کے ہراساں نقشے میں!
میں اپنے لہو سے رنگ بھرتے ہوئے!
زخمی ناقہ ٔلذت کا پھٹا محمل رفو کرتا ہوں
گلابوں میں سوسن و نسترن سجاتے ہوئے!
زعفرانی کھیتوں میں!
گمنام جزیروں سے چمپا اور چنبیلی بلاتے ہوئے!
پھول چنتی دھڑکنوں میں چراغ بن کے جلتا رہتا ہوں
نرم استعاروں میں آوارگی کی تشریح کرتا رہتا ہوں

حضرت مولانا عبد الغنی ’’حاجی صاحب‘‘ کا تعارف و خدمات

Allah has created this universe and for guidance of people he has sent his different holy books and with those books he has sent different holy messengers. The messengers of Allah came to this world and preached the message was written in his books. When his messengers completed their job then their duty was given to the scholars of Islam. They also preached Islam from place to place and they face many difficulties and hardships but they continue their message. Among all these scholars some of them worked hard for writing and teaching the holy Quran to other people. Molana Abdul Ghani is one of these scholars who spent all of his time to serve Islam and preaching of Islamic thoughts. In this paper will present the Services and Introduction of Molana Haji Abdul Ghani.

Synthesis and Characterization of Homo and Amphiphilic Block Copolymers of Poly 2-Vinylpyridine Stabilized Metallic Nonoparticles

This Ph. D. dissertation deals with the synthesis of metallic nanoparticles with P2VP homo- and block copolymers (BCP) as stabilizing agent, their characterization, and applications. As a summary of the research conducted during the course of Ph. D., a series of homopolymers of poly(2-vinylpyridine) and amphiphilic block copolymers of poly(2-vinylpyridine), includingpoly(2-vinylpyridine)-block-poly(methyl methacrylate) andpolystyrene-blockpoly(2-vinylpyridine) were used to stabilize metallic nanoparticles (gold and silver). Polymers containing pyridine moiety have been utilized as a stabilizing agent for the metallic nanoparticles. Among them poly(2-vinylpyridine) (P2VP) is the excellent candidates because nitrogen atoms of the pyridine moiety have a strong affinity for the metal ions and metallic nanoparticles that restrains the aggregation of the metal nanoparticles through steric stabilization. Furthermore, P2VP prompts the reaction at ambient temperature and reduction of the particle size with the increase in its molar mass. AuNPs stabilized by P2VP ligands were designed to offer atomic level control and an efficient scale-up production through control of the molar mass of P2VP. Molar mass of the P2VP has enormous effect on the stabilization, size and size distribution of AuNPs. The reducing activity of P2VP increased with the increase in its molar mass. The P2VP stabilized AuNPs are evaluated for their stability and applications using UV-visible spectrophotometry, FTIR, DLS and AFM. Moreover, the drug encapsulation efficiency of P2VP-stablized AuNPs increased with the molar mass of P2VP. P(S-VP)-AgNPs were used as nanosensor for the rapid quantitative assay of pesticide, cartap. P(S-VP)-AgNPs and its interaction with cartap was studied using UV-visible spectroscopy, FTIR, zetasizer and AFM. The synthesized nanosensor is selective towards cartap in the presence of other interfering pesticides in real samples. The LoD of the nanosensor for cartap is far below already reported sensors for cartap. Furthermore, P(2VP-MMA)-AuNPs modified GCE electrode was used as a novel electrochemical sensor for nicotine. It was found that sensitivity of bare GCE is significantly enhanced by coating with P(2VP-MMA)-AuNPs. The P(2VP-MMA)AuNPs modified GCE is more sensitive towards nicotine and gave more intense electrochemical response with reference to bare GCE. In addition, the morphology of P(2VP-MMA) copolymer thin films was studied using AFM. It was observed that both P2VP and PMMA block lengths, total molar mass of block copolymer, solvent used for casting, and substrate play an important role in the morphology of block copolymer thin film. Gold nanoparticles incorporated with the polymer are completely shielded by P2VP chains and influenced the morphology of block copolymer organization by enlarging the polymer domain. Furthermore, surface roughness and thickness increased with the increase in molar mass of the block copolymers.
