16. Al-Nahl/The Honey Bee
I/We begin by the Blessed Name of Allah
The Immensely Merciful to all, The Infinitely Compassionate to everyone.
16:01
Allah’s Judgment is coming.
So do not seek to hurry it – O the disbelievers.
All Glory be to HIM!
And HE is Exalted - far above what they ascribe to HIM in Divinity and Worship.
16:02
Tell them, O The Prophet, that everyone does not deserve to get the angels descend on to him.
HE sends down the angels with the Spirit by HIS Command upon whoever HE
Pleases of HIS servants, saying:
‘Warn people that there is no entity of worship except ME alone.
So keep away from MY disobedience’ in reverence, awe, and piety!
16:03
HE created the celestial realm and the terrestrial world in truth with a definite purpose.
HE is Exalted - far above what they ascribe to HIM.
16:04
HE created the human being from a drop of semen,
yet the same human being openly becomes a fierce adversary.
16:05
And the livestock - HE created them for you.
There is warmth in them - in clothing from their hides/wool - and other benefits,
and of them, you obtain meat to eat as well.
16:06
And there is beauty in them for you too -
when you bring them home in the evening, and
when you take them out to pastures in the morning.
16:07
And they carry your loads to distant far-off lands,
which you could not otherwise reach without hardship to yourselves.
In fact, your Rabb - The Lord is All-Gracious and All-Compassionate.
16:08
And HE...
In this article different era of ╓anaf┘ School of thought is discussed in which it is mentioned that ╓anaf┘ School got the general acceptance among people after the initial three stages of its Origination which lays the foundation of its Evolution and Promotion. First era is known as the era of “ Zahir ul Riw┐yah” renaissance starts from Hazrat Imam Ab┴ ╓an┘fa and moves on up to his disciple Hassan L┴lo’ (204 A.H.). There is no book found under the authorship of Imam Abu Han┘fa but his disciple R┐shid Al Mohammad has written various books. Some famous renowned books under the authorship of Im┐m Muhammad are Al J┐m‘ Alkab┘r (الكبري اجلامع, (Al J┐m‘ Al Sagh┘r (الصغري اجلامع, (Al Siyar Al kab┘r(الكبري السري, (Al Siyar Al Saghir(الصغري السري, (Al Mabs┴t(املبسوط (and Al Ziy┐d┐t(الزايدات.(Second era is known as Mas┐’l-e Naw┐dir. Books like Al-Kais┐niy┐t(كيسانيات َال, (AlH┐r┴niy┐t(اهلارونيات, (Al-Jurj┐niy┐t(رجانيات ُ اجل (and AlRuqiy┐t(ياتَّق َّ الر (are written under the authorship of Imam Muhammad during this era are consists of new topics that are not mentioned in the written books of earlier period.
This thesis has been divided into four chapters. The first chapter is about the introduction of polypyrrole (PPy) and other conducting polymers (CPs). The importance and drawbacks of conducting polymers have been thoroughly discussed followed by the discussion about the need of composites of these polymers. The importance of CPs-metal oxide composites over individual components has been deliberated. The relevant literature and references have also been included. The second chapter is related to the synthesis, characterization and analytical applications of PPy-vanadium penta oxide (V2O5) composites. The materials were synthesized in aqueous medium by chemical oxidation polymerization method using FeCl3.6H2O as an oxidant followed by characterization using Fourier transform infrared (FT-IR) spectroscopy, X-ray diffractometer (XRD), thermogravimetry analyzer (TGA), scanning electron microscopy (SEM), energy dispersive X-ray (EDX) technique, surface area and pore size analyzer, UV-visible spectrophotometry and LCR-meter. PPy was amorphous while the composites were crystalline in nature. The content of V2O5 improved the compactness, thermal stability, surface area and electrical conductivity of the composites. The band gap energy was found to be of the same value for all the composites. The gas sensing properties of the materials were checked for ammonia gas and some other organic liquid vapors. The composite PPy/8%V2O5 was of highest sensitivity and selectivity towards ammonia at room temperature. The limit of detection (LOD, response time and recovery time of this material was 1.4 ppm, 10.5 and 81.6 s, respectively. The performance of this composite has been compared with the reported data. In the third chapter, synthesis, characterization and analytical applications of PPy-MnO2 composites have been elaborated. The composites were synthesized and characterized by the same procedure as mentioned for Chapter-2. The content of MnO2 has almost same x effect on the properties of these composites as in case of PPy/V2O5 composites. However, the band gap energy was found to decrease continuously with increase in the percent amount of MnO2 in the composites. After studying the gas sensing characteristics, the composites PPy/10%MnO2 was found of unique properties with respect to its sensitivity, selectivity and limit of detection towards ammonia gas. The response of this material was far better than the already done work. The LOD was 0.4 ppm with response and recovery time 32.1 and 40 s, respectively. In the fourth chapter, unique PPy/V2O5-MnO2 hybrid composites has been synthesized, characterized and applied as gas sensor by the same methods as discussed for PPy/V2O5 composites. These materials were also applied as gas sensor. The composite PPy/4%V2O5-5%MnO2 (S3) was of better performance as compared to the reported hybrid composites regarding ammonia gas sensitivity. The LOD, response and recovery time of the material at room temperature was 5 ppm, 75 and 76 s, respectively.
