Currently the field of nanocatalysis is undergoing many exciting developments and the design of silica-based organic-inorganic hybrid nanocatalysts is a key focus of the researchers working in this field.This book aims to present a succinct overview of the recent research progress directed towards the fabrication of silica-based organic-inorganic hybrid catalytic systems encompassing the key advantages of silica nanoparticles and silica-coated magnetic nanoparticles in an integrated manner. Featuring comprehensive descriptions of almost all approaches utilized for the synthesis of nanomaterials including some latest techniques such as flow and microwave-assisted synthesis that enable large-scale synthesis, it proves useful not only to academics but also industrialists. It also includes a systematic discussion on the vital characterization techniques employed for authenticating the structure of these.The title also offers an enormous amount of knowledge about the fusion of nanotechnology with green chemistry that strives to meet the scientific challenges of protecting human health and the environment.

How do borderland dwellers living along militarised frontiers negotiate regimes of state security and their geopolitical location in everyday life? What might 'freedom' mean to those who do not resist captivity engendered by borders? Focusing on the predicaments of a double-minority, Freedom in Captivity examines the affective attachments, political imaginaries, and ethical claims-making among the Shia Muslims of Kargil. In contrast to calls for freedom in the Kashmir Valley, Shias on the frontiers of Kashmir have sought belonging to India. Yet they do not entirely succumb to its hegemonic ideological boundaries. Departing from the dominant focus on physical cross-border mobility, this book is an invitation to reimagine borderlands as cartographies of ideas, cutting across spatial scales. Based on original ethnographic research conducted between 2008 and 2021, this monograph offers a unique long durée insight into the lives of people residing at the intersections of the biggest states in Asia.
