مو لانا عبدالصمد رحمانی

مولانا عبدالصمد صاحب رحمانی
دوسرا حادثہ مولانا عبدالصمد صاحب رحمانی نائب امیر شریعت صوبہ بہار و اڑیسہ کا ہے وہ بھی پرانی یادگار، اس دور کے نامور عالم اور ملک و ملت کے پرانے خدمت گزار تھے، ملکی و ملی تحریکات میں ان کا نمایاں حصہ رہا، خلافت اور ترک موالات کی تحریک اور ہندوستان کی آزادی کی جدوجہد میں مولانا سجاد بہاری مرحوم کے رفیق کار تھے، ان کی وفات سے ایک قدیم یادگار اٹھ گئی، اﷲ تعالیٰ ان کے مدارج بلند فرمائے۔
(شاہ معین الدین ندوی،جون ۱۹۷۳ء)

مکالمہ بین المذاہب شرائط، مقاصد جديد

Now the whole world is the global village. The science has brought revolution in every field of life. Man has made a lot of things for his comforts, discomforts, reliefs and destruction. Now the time has come for us to take evolutionary steps to save us from giant’s destruction, terrorism, extremism, intolerance and unrest which are the machinations of complete annihilation over the earth, which needs cosmopolitanism on our part For this purpose, dialogue can play a vital role. People belongs to different civilizations, cultures, societies, nations and religions can sit around the table beings humans and can solve religious, political, geo political and economical problems by enhancing mutuality and common understanding. Dialogical aim should be to avoid clash of civilizations and peace for everyone. Terrorism and extremism should be stopped and we should promulgate coexistence and peace for whole human community. Purpose should be to serve the humanity. We should promote love, peace, respect for the other religions; serve humanity create equality and equity among human beings. This should be safety of present and coming generation. We should pay our role as super creature and thinking creature; super. The barriers which come across while promulgating cosmopolitanism and expatriation is seemed to be is the double standard of the west, that promotes colonialism, terrorism, extremism and economical support of missionaries and these things are the real problems for those human beings who take serious trenchant and serious efforts to achieve dialogical goals cannot achieve it. The role western media plays; is not supportive to this nation. Western world especially American should use her hegemony to make world worth living and worth seeing to the coming generation.

Natural Colorants As Photosensitizers for Dye-Sensitized Solar Cells Dsscs for Green Enconomy

Twenty five natural dyes (D1-D25) were extracted through maceration from local plants species categorized as A= D1-D6, B= D7-D17, C= D18-D20, D= D21-D22, E= D23 and F= D24-D25 on the basis of their parts used for the application in dye sensitized solar cells (DSSCs). The photo-physical and electro-chemical behaviors of natural dye were evaluated through UV-visible spectrophotometry and cyclic voltammetry respectively. The UV-Visible absorption spectrum of the individual dye extracts D1-D25 revealed two distinct bands i.e. First band corresponds to π-π* transition while the second band corresponds to intermolecular charge transfer (ICT) band. Out of all the extracted natural dyes, S. oleracea (D23-E) dye resulted in best absorption at ICT band with λmax = 662 nm having absorbance A= 0.33. Cyclic voltammetry of the dyes D1-D25 was carried out which revealed the distinct oxidation and reduction peaks. The peaks can be seen more prominently among S. oleracea (D23-E), R. tinctorum (D21-D) and H. rosa-sinensis (D1-A) dyes while rest of the dyes exhibited less prominent peaks. The photovoltaic performances of the individual dyes D1-D25 (A-F) were evaluated by fabricating the sandwich-type DSSCs with the extracted natural dyes. TiO2 coated FTO glass slides were prepared for dye adsorption. The J-V profiles showed open circuit voltage values and short circuit current density. The most promising results of photovoltaic parameters were found for solar cell fabricated with D23-E dye with Jsc= 5.38 mA/cm2 and Voc= 0.47 V followed by D21-D (Jsc=4.14; Voc= 0.36 V) and D1-A (Jsc= 5.48; Voc= 0.36 V) respectively The best sunlight to energy conversion efficiency was obtained from D23-E (η= 1.4%) dye which has better UV absorption and oxidation properties. The respective dye gave high short circuit current density and hence high photon to current efficiency was achieved. Other dyes gave the efficiency in the following order D21-D (R. tinctorum) = 1.1% > D22-D (A. tinctoria)= 1.05% > D1-A (H. rosa sinensis)= 1.02% > D17-B (S. anacardium)= 0.92 > D2-A (B. oleracea var. capitata) & D11-B (P. granatum) = 0.9% > D6-A (R. macdub)= 0.8% > D19-C (B. vulgaris) = 0.7%. Other natural dyes also showed satisfactory results. These natural dyes can easily replace conventional harmful, persistent and expensive metallic and synthetic dyes. Natural dye can be regarded as a promising candidate for low cost DSSCs fabrication with no environmental damage.
