انصاف کی فراہمی ترقی کا زینہ

انصاف کی فراہمی ترقی کازینہ
نحمدہ ونصلی علی رسولہ الکریم امّا بعد فاعوذ بااللہ من الشیطن الرجیم
بسم اللہ الرحمن الرحیم
معزز اسا تذہ کرام اور میرے ہم مکتب شاہینو!
آج مجھے جس موضوع پر لب کشائی کرنی ہے وہ ہے:’’انصاف کی فراہمی ترقی کازینہ‘‘
صدرِذی وقار!
اس دنیاو مافیہا میں انسان جہاں کہیں بھی آباد ہے وہ اس بات کا متمنی ہے کہ اسے اعلیٰ مقام مل جائے ، اس کو مقام ارفع پرمتمکن کر دیا جائے ، اسے زندگی کی جملہ راحتیں میسر آ جائیں ، اس کی زندگی کے اندھیرے اجالے میں بدل جائیں، اس کے گلشن ہستی میں بہار آجائے ، اس کے آنگن میں عروج وترقی کے گلہائے رنگارنگ کھل اٹھیں۔
جنابِ صدر!
اگر کوئی رشوت ستانی کے ذریعے، اقربا پروری کے ذریعے، کساد بازاری کے ذریعے، انارکی کے ذریعے، دھوکہ دہی کے ذریعے ، فریب کاری کے ذریعے، ڈاکہ زنی کے ذریعے، نمودونمائش کے ذریعے ، اور چرب زبانی کے ذریعے ترقی کی منازل طے کرناچاہتا ہے تو یہ اس کی خام خیالی ہے۔
صدرِمحترم!
عروج و ترقی کی منازل اگر طے کرنی ہیں تو اقلیم عقل وخرد کی فرمانروائی کو ترک کرنا ہوگا عقل کل کے تصور کی دلدل سے نکلنا ہو گا ، تساہل وغفلت کی عبا کو تار تار کرنا ہوگا، جہد مسلسل اور پیہم کد و کاوش کی خلعتِ فاخرہ کو زیب تن کرنا ہوگا مزید برآں عدل و انصاف کے دروازے پر دستک دینا ہوگی۔
جنابِ صدر!
قرآنِ مجید میں ارشادِ باری تعالیٰ ہے کہ ’’اعدلوھو اقرب للتقوی ‘‘ انصاف کرویہ تقو ی کے زیادہ قریب ہے، اورمتقی انسان دنیامیں مقامات رفیعہ کا وارث ہوتا ہے۔ اور آخرت میں بھی حور قصور کے وعدے اس کے لیے ہوتے ہیں ،متقی انسان کی عظمت کے ڈنکے دنیا اور آخرت میں بجائے جاتے ہیں۔...

اسلامی ریاست میں قیادت کے راہنما اصول اسلامی تعلیمات کی روشنی میں

Islamic state is responsible to provide the means of protection for its inhabitants. It is the religious and spiritual duty of Islamic state to protect the Islamic culture and civilization as well so that the Muslims could perform their religious and social duties freely. Likewise, an Islamic state is supposed to ensure justice into the society. It indicates that establishing an Islamic state is core responsibility of Muslims so that they could practice their religion in free atmosphere and religious leadership. In this connection, the purpose of this research paper was to explore the principles of leadership in an Islamic state. The qualitative and descriptive research methodology was employed for the collection and analysis of data. The review of literature revealed that Muslim scholars have given particular emphasized on establishing the Islamic state. Moreover the jurists have counted the essential qualities in Islamic leadership. In this context, this article has dealt with the ideal principles which are necessary for the Islamic leadership. These principles are extracted from Qur’ān, Sunnat and. (صلى الله عليه وسلم) Prophet Holy of life

Study of Dielectric Properties of Various Graphene/Metal/Polymer Nanocomposites

The aim of the present research work is to synthesize flexible polymer based nanocomposites with excellent dielectric properties. Compounds and composites with high dielectric constant are in demand in electronic industry due to their ability to store more charge, while energy dissipation is low there. So it is needed to synthesize materials with ability to store more and more charge. In presented research work, flexible three phase nanocomposite films of graphene/metal/polymer were synthesized with reasonably high dielectric constant or real part of permittivity and very low dielectric loss or imaginary part of permittivity. Ternary nanocomposite films were synthesized by using three different polymers i.e., poly(vinyl alcohol), polyvinylidene fluoride and polydimethysiloxane as matrix. Graphene and two ceramic metals oxides i.e., titania and barium titanate were reinforced in the polymers as conducting and metal additives, respectively. In this way six different types of ternary nanocomposite films with different combinations of fillers and polymers were synthesized. Each ternary nanocomposite series was synthesized by varying w/w of graphene while keeping concentrations of ceramic and polymer constant. After setting optimized conditions for concentrations of graphene, w/w of ceramic filler was varied and concentrations of ceramic and polymer were kept fixed. Each ternary graphene/metal/polymer nanocomposite film was characterized by scanning electron microscopy, X-ray diffraction analysis, raman spectroscopy, fourier transform infrared spectroscopy and thermal gravimetrical analysis to study their morphology, structures, presence of functional groups and thermal stability respectively. Dielectric characterization of each ternary graphene/metal/polymer nanocomposite film was carried out at room temperature. Ternary nanocomposite with highest dielectric constant and lowest dielectric loss were explored for each ternary nanocomposites series. Dielectric constant of poly(vinyl alcohol), Polyvinylidene fluoride and polydimethysiloxane was increased from 13.3, 20.5 and 6.5 to 330, 159.8 and 108.3, respectively, with addition of graphene and titania. While dielectric constant of poly(vinyl alcohol), Polyvinylidene fluoride and polydimethysiloxane was increased from 13.3, 20.5 and 6.5 to 66, 199.9 and 116.9, respectively, with addition of graphene and barium titanate. Even with such high dielectric constant, dielectric loss of all ternary nanocomposites was still very low i.e., less than 5 which is required for energy storage devices. AC conductivity and complex electric modulus of all neat polymers and ternary graphene/metal/polymer nanocomposite films were also calculated and compared. The superiority of this method is that synthesized three phase graphene/ceramic/polymer nanocomposite films have hybrid properties like high dielectric permittivity and low dielectric loss of fillers and flexibility and mechanical strength of polymers. All analyses of graphene/metal/polymer nanocomposite films confirm their excellent capacitive performance. On the basis of results it is concluded that synthesized ternary graphene/metal/polymer nanocomposite films are fairly good candidate to be used as dielectric medium in energy storage devices like capacitors.
