The book explores the innovative field of green nanotechnology, focusing on the synthesis of nanoparticles using environmentally friendly biological methods. It highlights the use of medicinal plant extracts, specifically from Adiantum, combined with silver nitrate, to produce silver nanoparticles. Key indicators of nanoparticle formation, such as color change and UV-Vis spectrometry, are discussed, along with X-ray diffraction analysis revealing grain size and structure. Additionally, FTIR spectra confirm the functional groups present in the synthesized nanoparticles, showcasing their unique properties.

Focusing on the evolution of Muslim reformist political thought in Bukhara, this book offers a comprehensive analysis of key trends in the region. It stands out for its use of original sources from Soviet archives, providing insights that were previously unavailable to Western scholars, thus enriching the understanding of the historical and political context of the area.

This book is based on the ethnographic study conducted in Imambargah Hussainyia in Rural Jhang, Pakistan. The main aim of this research was to investigate the ways of Muharram rituals performance among the Shi a devotees in the locale. Researchers have used mix methods to investigate the intensity and magnitude of the rituals performance. The inhabitants perform following rituals during the month of Muharram; matam, majales, taziya, processions, alam, zuljinah, langar, and visitation of the holy shrines. According to Shi a Muslims, these rituals were started soon after the incident of the Karbala in 61 year of Islamic Calendar. With the passage of time, these rituals matured and altered by the devotees of differences races and regions. In the present study area, people practice these rituals as a part of their daily activities and they love to practice the teachings of their Imams. For the community members, Muharram is a month of symbolic association of the Shi as towards their Imams. Practices they perform are venerating them to the cohesion and letting them to develop a strong association at communal level.

Die grüne Nanotechnologie nutzt umweltfreundliche Methoden zur Herstellung von Nanopartikeln, insbesondere durch biologische Verfahren. Dabei kommen Extrakte von Heilpflanzen wie Adiantum und Silbernitrat zum Einsatz. Eine Farbänderung von farblos zu rotbraun signalisiert die Bildung von Nanopartikeln, die durch UV-Vis-Spektroskopie und Röntgenbeugungsspektroskopie (XRD) weiter untersucht werden. Die Analyse zeigt, dass die Silbernanopartikel eine durchschnittliche Größe von 14 bis 17 Nanometern besitzen und die FTIR-Spektren bestätigen die vorhandenen funktionellen Gruppen.

A nanotecnologia verde é um campo emergente que utiliza nanopartículas de 1 a 100 nanômetros. O método biológico, que utiliza extratos de plantas medicinais e nitrato de prata, é eficiente e ambientalmente amigável. A formação de nanopartículas é indicada pela mudança de cor e confirmada por técnicas como UV-Vis e difração de raios X.
