کوئی بھی درمیاں حائل نہیں ہے
بظاہر اب کوئی مشکل نہیں ہے
مجھے لگتا ہے یاں پہ ایک پتھر
ترے سینے میں جیسے دل نہیں ہے
محبت کیا ہے بس نقصان دل کا
سوائے غم کے کچھ حاصل نہیں ہے
طبیعت کو نہ جانے کیا ہوا ہے
کہ بھاتی اب کوئی محفل نہیں ہے
مرے قاتل ہیں میرے یار تائبؔ
زمانہ تو مرا قاتل نہیں ہے
Before Islam, women were victims of slavery, humiliation, oppression, and exploitation. Islam came and liberated women from slavery, humiliation, oppression, and exploitation. Islam abolished all the evil customs which were against the human dignity of women and gave them the rights which they deserved. The Prophet (peace and blessings of Allah be upon him) endowed women with their rightful status and human dignity on both social and domestic levels. In the light of Islamic teachings, men and women have equal status as human beings. In that sense, no one is superior to another. Just as Islam calls men honorable and respectable, so too in the eyes of Islam women are honorable and have an important role to play in society. The biography of the Holy Prophet is a beacon for us. He proved by his practical life that a woman is pitiable and respectable in respect of mother, daughter, sister, wife, and other relationships. In Arab society, he proved by raising her four daughters that a woman is also a human being, therefore, she should also be given rights. The Prophet (peace and blessings of Allah be upon him) has left out such enlightening teachings on women's social rights that by following them, women can be granted their social rights. But even today, women are being deprived of many of their social rights. There is a need to bring the social issues of women before the society in the light of Sīrat-un-Nabī. Also mention the restrictions facing women in the present. The question arises, what is the social status of women in the light of Sīrat-un-Nabī? And what are the challenges facing women today? This article is written to answer these questions. In pre-Islamic society, women were not given any importance or status in any relationship. Socially, women's rights were completely taken away and some Arab families did not even have the right to live.
The development of new functionalized materials with increased performance is growing to meet the regulatory standards in response to public concerns for environment. This dissertation is an effort in this direction and describes the synthesis, characterization, and application of various functionalized silica hybrids keeping the perspective of recent technological advancements. The objective of present research is mostly driven by inadequate control of increasing concentration of toxic pollutants in environmental compartments. The synthesized functionalized hybrids are expected to find progressively their place as economical adsorbents. The direct method adopted for the synthesis of Mesoporous Silica and its functionalized hybrids offers advantage of providing uniform surface coverage and better control of the amount of incorporated organic moiety. The synthesized products are grouped as Mesoporous Silica (SBA- 15, MSU-H), Monodispersed ORMOSILS (VO, PO, MO), Functionalized Silica Hybrids (AS, GS, MS, VS, PS, AM, GM, MM, VM, PM), and Polysulfone Mixed Matrix Membranes (PM-15, PM-H, PM-VO, PM-PO, PM-MO). The resulting hybrid materials are thoroughly characterized to determine the surface and bulk properties and to develop understanding of intricate relationship of structural artifacts with its functionalities as adsorbents. The characteristics Si–O–Si stretching vibration bands at 1047cm-1 for Mesoporous Silica is identified on ATR-FTIR. The peculiar hexagons image is scanned under SEM. Further, the distribution of Si, O, and C element to locate the binding sites on fabricated membranes is clearly demonstrated through Mapping. The surface area of 521-580 m2/g is calculated by BET for Mesoporous Silica. The thermal stability is assessed by TG/DTA analysis. The synthesized Mesoporous Silica based hybrids were subjected to 13 C and 1H NMR studies and possible structure is deduced. The selection of novel adsorbents with multiple and diverse application range is a challenge. In the same spirit, the functionalized silica based hybrids are applied in batch mode for the removal of toxic species prevalent in air (N2, Polycyclic Aromatic Hydrocarbons-PAHs), soil and water (metal cations of Hg, As, Cr, Pb, and nitro-, amino-phenols). Each adsorbent demonstrates the removal efficiency for these pollutants. The qualitative performance scale of each adsorbent is characterized as Excellent for Chromium, Very good for Lead, Good for Arsenic and fairly good for Mercury. A general comparison of silica based hybrids as adsorbents for the removal of PAHs and Phenols highlight the different efficacy extent. Phenols are observed to take the lead by showing more adsorption than PAHs. Larger molecular weight and fused aromaticity likely appear as hindrances to better retention of selected PAHs. It is concluded that Mesoporous silica better retains the liquid pollutants (metals, phenols) attributed to its larger surface area. Desorption for SBA-15 and MSU-H follows Type IV and Type I hysteresis, respectively. It is reported here that –phenyl and –methacrylate substituted ORMOSILS (PO and MO) did not construct the breakthrough curve and deformed because of non-sustainability under the applied temperature-pressure conditions. It is generally concluded from the results that basic silica framework offers good adsorptive properties. Further, adsorption in functionalized hybrids is facilitated through binding sites provided by organic moiety. The present study, thus, proposes a decontamination model for pollutants ranging from metal cations to gases. The efficient removal with regeneration capacity offer direct compliance to 3R principles. That is to Reduce (pollutants), Reuse and Recycle (functionalized hybrids/membranes). It is expected that these materials will help to reduce the pollution load on the environment. The possibility for commercialization of mixed matrix membrane is also important output of this research. The application of these materials in existing industrial processes is another avenue to find niches for applications in advanced waste water treatment technologies with no comprise on improved industrial production and sustainable environment.
