امام شعرانیؒ اور شاہ ولی اللہؒ کے فقہی نظریات کا تقابلی مطالعہ

Allah Almighty has created such men in every age for the protection of the religion of Islam whose ijtihād and da'wah deeds have always defeated the false ideologies by proving the legitimacy of Islam on firm grounds. From those blessed ones, Imām Sha'rānī and Shāh Walīullāh are eminent, intellectual, spiritual and rejuvenating personalities of their time. The main purpose of this article is to make a comparative study in the context of the views of each of the above two personalities from different angles regarding the differences in jurisprudence. This paper also aims to highlight the rational and moderate position of these personalities while making their different opinion in comparison to other scholars, so that researchers and scholars of this age may get guidance regarding how to make different opinion. It will help the researchers to take advantage of these blessed attitudes of the ancestors and play an important role in building a peaceful society.

Synthesis and Characterization of Tungstate Based Nanomaterials for Multifarious Applications

Group-VIB particularly tungstate based nanostructured materials with novel morphologies demonstrate significant photocatalytic activity as compared to conventional photocatalyst (TiO2), however it exhibits low response in the visible region of light spectrum. In this scenario doping or coupling with other materials of lower band gap results in enhanced surface area, higher electron- hole generation rate, reduced band gap effectively increasing the catalytic and sensing response. This study is aimed to focus on tungstate based nanomaterials namely Bi2WO6, PbWO4, ZnWO4 and CdWO4. In our research, we covered following aspects of the nanomaterials; synthesis, characterization, growth mechanism and applications. The hydrothermal synthesis method was adopted for the preparation of desired nanomaterials and then their structural, morphological, compositional characterization were performed using high tech facilities like TEM, XRD, FESEM, XPS, FTIR, DLS, PL, BET and EDX. The promising reaction mechanism of theas-prepared metal tungstate nanostructures were discussed systematically. Novel morphologies (nano-flakes, nanowires, nanoflowers and nanorods, etc.) were fabricated by optimizing the reaction parameters. The photocatalytic response of the nanostructures were evaluated by degrading the model organic Coomassie brilliant blue (CBB), Congo red (CR) and Methylene Blue (MB) dyes.Electrochemical bio-sensing, the horseradish peroxidase-like (HRP) activity and hydrogen storage features were also evaluated.
