مولانا عبدالباری ندوی
افسوس ہے مولانا عبدالباری ندوی کاگزشتہ مہینہ ایک طویل علالت کے بعد ۸۲برس کی عمر میں ان کے وطن لکھنؤ میں انتقال ہوگیا۔ مولانا کے نہایت ذہین اور طباع ہونے کی دلیل اس سے زیادہ اورکیاہوسکتی ہے کہ ان کی اصل تعلیم قدیم طریقہ کے مطابق عربی اورفارسی کی تھی اور انگریزی غالباً ہائی اسکول تک پڑھی تھی لیکن اپنے ذاتی مطالعہ اورشوق سے انھوں نے انگریزی میں اتنی استعداد بہم پہنچائی کہ اولاً فلسفۂ یورپ اورثانیاًسائنس کا مطالعہ کرسکیں۔فلسفہ سے انھیں خاص مناسبت تھی، چنانچہ اس میں ایساکمال حاصل کیا کہ برکلےؔ،برگسانؔ اورڈیوڈ ہیوم پر انھوں نے کتابیں لکھیں اور ان کی بعض کتابوں کا اردو میں ترجمہ کیا اورنہ صرف یہ بلکہ عثمانیہ یونیورسٹی میں پہلے فلسفہ کے لیکچرر اورپھراس کے ریڈر مقرر ہوئے۔ اسی زمانہ میں سیرت النبیؐ مصنفہ مولانا سید سلیمان ندوی کی جلدسوئم کے قدیم ایڈیشن میں مرحوم نے معجزات پرجو ایک باب لکھا تھا وہ زبان وبیان اوراستدلال و استنتاج کے اعتبار سے ایک نہایت اہم مقالہ کی حیثیت رکھتاتھا۔
طبع سلیم اگر رہنما نہ توفرط ذہانت اورفلسفہ کے ساتھ انہماک وتوغل بسا اوقات گمراہی کا سبب ہوجاتے ہیں، چنانچہ مرحوم کے ساتھ یہی ہوا، زندقہ والحاد کا شکار ہوگئے۔ ایک مدت کے بعد جب مولانا تھانوی سے بیعت ہوئے تو فلسفہ کا ردعمل اس شکل میں ہوا کہ مذہب کارہبانی تصور غالب آگیا، غرض کہ وہ زمانہ میں ع

Peace is the key source of all virtues. Unfortunately, since long all the world especially Muslim ummah is facing extremism and terrorism. It is very tragic are mostly those who are having the labels of Islam. One of the many reasons for this is the weakness of beliefs. Today many people have misconceptions about basic beliefs of Islam. Such people are responsible for destroying the peace of society. The best and easy solution to avoid all these riots and setting up peace is to focus on improving their beliefs. Without this the desire to establish peace is nothing more than a dream. In spite of the intention of eliminating the riots with the latest cameras, sensors, radar and all the richest resources available in the world's developed countries. There is not a single woman who travels far away from the remote and is not afraid of anyone except Allah. But the Islam, fourteen centuries ago, showed that a woman travelled alone from?ir? To Makkah and would not have been afraid of anyone except Allah. It was possible only when the prophet (pbuh) spent his life preaching in Makkah about the purification of beliefs. In history, it is always a tradition that whenever corruption is increased on earth, Allah altered this corruption by the prophets and all the prophets started their mission with correction of beliefs.
Wide band gap semiconductors are the key components to make laser diodes and blue and green LEDS. They are being used in power switching and high temperature applications. The bandgap of ZnS is tuned by adding an impurity such as Mg that is useful for optoelectronic devices. Earlier reports indicate that there is slight blue shift in the band gap energy of Mg-doped ZnS but we have observed a reasonable red shift (3.48 eV to 2.58 eV) in ZnS band gap energy in Mg-doped ZnS structures. Theoretical model, based on first principle theory using local density approximation, has shown consistent results on Mg-doped ZnS structure. The present research work deals with as-grown and Mg-doped ZnS structures. A series of samples of ZnS with varying x content of Mg have been prepared with x= 0.0, 0.1, 0.2 and 0.3M by Sol-gel method using magnesium nitrate (Mg(NO3)2.6H2O), thiourea (SCN2H4) and zinc sulfate (ZnSO4.7H2O) for thesources of Mg2+, S2- and Zn2+ ions respectively. Ammonium hydroxide (NH3H2O) was used as a stabilizing agent and hydrazine hydrate (N2H4.H2O) was used as a complexing agent. The optical and structural properties were inspected as a function of Mg-concentration. The electrical, optical, morphological and structural properties were studied by different characterization techniques like XRD, SEM, FTIR, Hall measurements, EDX and UV-Vis Spectrometer. The cubic zinc blende crystal structure of ZnS:Mg was observed by the XRD. By SEM the crystallite size was found in micrometer (35nm for Mg=0.3). It has been concluded that with an increase of Mg-concentration in ZnS the crystallite size augments. The results of EDS show that the zinc and sulphur are major components in the composition of ZnS which confirms the purity of ZnS powder. In FTIR spectrum with range 500-4000cm-1, absorption peak was observed at 674cm-1 which confirms the ZnS synthesis. UV-Visible spectrophotometry results confirm the red shift in the bandgap energy of ZnS with Mg. The computational results performed by Quantum-ESPRESSO confirm the red shift band gap trend so as to support the experimentally determined results, only subject to the condition that Mg atoms substitute into ZnS structure. The additional related work deals with the sol-gel synthesis of BaTiO3 and Sr- doped BaTiO3 thin films having the composition BaTiO3+xSr (0 ≤ x ≤ 0.4) on Ti-substrate by spin coating. The barium acetate (Ba (C2H3O2)2), titanium (iv) n-butoxide (C16H36O4Ti), and strontium acetate (Sr (C2H3O2)2·2 H2O) were taken as preliminary materials. The starting materials were taken according to the stoichiometric proportions and mixed carefully in aqueous phases for uniform compositions. First of all barium acetate was dissolved in heated glacial acetic acid and then strontium acetate was added to this solution while stirring it so that all the particles were dissolved. After that a stoichiometric amount of titanium (iv) n-butoxide was dissolved in 2-methoxy-ethanol and added to the solution still under stirring. To stabilize the solution, ethylene glycol was added in proportion of 1:3 to acetic acid. The final solutions that were used for spin coating on titanium substrates have a concentration of 0.4 M. The structural, morphological and electrical characteristics of the Sr-doped BaTiO3 were studied. The X-ray diffraction results of BaTiO3 and Sr-doped BaTiO3 show the enhancement in the crystallinity of the films by increasing Sr-content. SEM measurements of doped and undoped BaTiO3 films reveal their uniform and cracks free nature. The P-E measurements of these thin films show the reduction in the ferroelectric properties with increasing the Sr content.
