مولانا عبدالکریم پاریکھ
یہ خبر بڑے رنج و افسوس کے ساتھ سنی جائے گی کہ ممتاز عالم دین اور مشہور ملی رہنما مولانا عبدالکریم پاریکھ ۱۱؍ ستمبر ۲۰۰۷ء کو ناگ پور میں وفات پاگئے، جہاں ان کا خاندان گجرات سے آکر آباد ہو گیا تھا، وہ ۱۵؍ اپریل ۱۹۲۸ء کو اکولہ (مہاراشٹر) میں پیدا ہوئے تھے، ابتدائی تعلیم حاصل کر کے یہیں کولڈ ڈرینگ ہوٹل میں ملازمت اختیار کرلی، پھر اپنا کاروبار شروع کیا جس میں اﷲ نے بڑی برکت دی اور جلد ہی وہ ناگ پور میں لکڑیوں کے بڑے تاجر شمار کیے جانے لگے۔
کاروباری مشغولیت کے ساتھ علم و مطالعہ اور دین سے بھی ان کو شغف رہا، اسی اثنا میں ان کا تعلق مولانا سید ابوالحسن علی ندویؒ سے ہوا جو روز بہ روز بڑھتا گیا یہاں تک کہ ان کے خلیفہ مجاز ہونے کا فخر حاصل ہوا، مولانا علی میاں ان کی بڑی قدر کرتے اور انہیں اپنے ساتھ جلسوں میں لے جاتے اور ان سے اصلاحی و دعوتی تقریریں کراتے۔
مولانا علی میاں نے پیام انسانیت کی تحریک شروع کی، جس کا مقصد اسلام کے بارے میں غیر مسلموں میں پھیلی ہوئی غلط فہمیوں کا ازالہ اور یہ بتانا تھا کہ اسلام ساری انسانیت کے لیے دین رحمت ہے، اس کی تعلیم امن و آشتی، انسان دوستی، اخوت، بھائی چارگی اور اتفاق و اتحاد کی ہے، فتنہ و فساد اور ظلم و جارحیت سے اس کا کوئی تعلق نہیں، اس تحریک میں مولانا عبدالکریم پاریکھ حضرت مولانا کے دست راست ہوگئے تھے اور ان کی تقریروں سے غیر مسلموں کو بڑا فائدہ پہنچتا تھا۔
مولانا عبدالکریم پاریکھ کی جانب مولانا علی میاں کا اعتنا دیکھ کر ندوے کا ہر شخص ان کا گرویدہ ہوگیا تھا اور وہ ندوہ کے مختلف معاملات میں دخیل اور اس کی کئی کمیٹیوں کے ممبر بھی...
Islam and Mysticism or tasawuf have coexisted. Sufism has flourished in all Muslim dominated regions. Sufism is a mode of spirituality within Islam. Sufi schools teach three parts: Shariah, Tariqah and Haqiqh. In this article, traditional thoughts in Sufism and its impacts on the world especially in the region of Indo-Pak have been discussed. The shrines of Pakistani Sufis are the centers of inspiration for mysticism and spirituality that influence cultures and civilizations.
Fuel cell is an emerging, cleanest, environmental friendly and pollution free technology, which converts chemical energy of fuel into electricity, heat and power without combustion. Fuel cells are categorized according to their electrolytic materials and working temperature. Solid oxide fuel cell (SOFC) is the most dominant and prominent among the fuel cell family. In other words, fuel cell is one of the most competitive candidates that could provide possibly accomplishments. Conventionally, Ni-YSZ cermet anode is used in SOFC, which works in the temperature range of 800-1000oC. Although this anode possesses a high electrochemical activity, high performance as well as electronic conductivity yet it requires a high working temperature to achieve the optimal results. Its high working temperature is the present draw back which becomes a major barrier to its commercialization. If this cell has to be commercialized then there is need to find suitable electrode materials that can operate successfully at low operating temperature. Keeping this in mind, many new electrode materials have been introduced in the present work, which have been classified into two groups; one is containing Ni partially while the other is completely Ni free. New electrode materials were prepared by introducing nano technique using either dry or wet chemical method with an added advantage of low manufacturing temperature. In order to fabricate a complete fuel cell, the compatible electrolyte materials were also prepared by co-precipitation method. These materials exhibited an excellent performance at comparatively low temperature (400-600 oC). For SOFC electrode and electrolyte purpose, CuNiZnGdCe (CNZGC), Al0.1NixZn0.9-x (ANZ), Cu0.2Mn0.2Zn0.6 (CMZ), Ba0.05Cu0.25FexZn0.7-x (BCFZ) Ba0.15Fe0.10Ti0.15Zn0.60 (BFTZ), Ba0.4Sr0.6Co 0.3Mn0.7 (BSCM), La0.1Sr0.9Co0.2Zn0.8 (LSCZ), Na2CO3-K2CO3- Ca0.2Ce0.8 (NK-CDC) and Gd0.1Ce0.9-Y2O3 (Y-GDC) materials were successfully synthesized by solid state reaction method or wet chemical and co-precipitation method. These electrodes and electrolyte materials were characterized by XRD, SEM, TEM, electrochemical and electrical techniques. It has been found that the BCFZ-5 having a composition of Ba0.05Cu0.25Fe0.10Zn0.60 shows an electrical conductivity equal to 25.84 at hydrogen atmosphere. It also exhibited the maximum power density of 741.87mW/cm2 and 933.41mW/cm2 for symmetrical and asymmetrical fuel cell testing schemes. On the basis of these results, BCFZ-5 material is considered a promising electrode/anode candidate for low temperature solid oxide fuel cell. Different approaches have been implemented to reduce the present cost of electrode and electrolyte materials for solid oxide fuel cell. For example; I. II. Use of cheap raw material Lowering of sintering temperature III. Reduction of sintering time IV. Lowering of operating/working temperature It has been noted that the substitution of zinc compound Zn(NO3)2.6H2O in place of nickel oxide (NiO) has reduced the cost by a factor of ≈25 in addition to the lowering of manufacturing and operating temperature, which also reduces the cost indirectly by saving energy and time. Moreover, the cost has been further reduced by a factor of 35 and 18 when samarium nitrate Sm(NO3)3.6H2O and gadolinium nitrate Gd(NO3)3.6H2O are respectively replaced by calcium nitrate Ca(NO3)2.4H2O. The lowering of working temperature from 1000 to 550oC is a major achievement that would not only reduce the running cost yet it may help in commercialization of solid oxide fuel cell. In a nut shell the electrodes and electrolytes proposed in the present work have successfully lowered the manufacturing as well as working temperature and hence the operational cost along with a significant reduction in the manufacturing cost of solid oxide fuel cell (SOFC).
