Metal Matrix Composites by Friction Stir Processing

By: Ranjit Bauri,Devinder Yadav

Metal Matrix Composites by Friction Stir Processing discusses the capabilities of utilizing friction stir processing (FSP) as a tool to manufacture new materials, such as composites. FSP is considered a tool for grain refinement. However, this work illustrates how FSP has a wider capability due to the material flow and mixing the process offers. This book highlights such aspects by demonstrating the ability of the process to incorporate a second phase and make metal matrix composites (MMCs). The book covers the current research on processing MMCs by FSP, and presents a novel approach of making ductile MMCs by FSP using metal particle reinforcements. - Demonstrates how friction stir processing can be used to make metal matrix composites - Includes a review of different approaches of making metal matrix composites by friction stir processing - Demonstrates the utility of friction stir processing in making new types of non-equilibrium ductile composites - Provides a comparison of properties of friction stir processed composites to those of conventional metal matrix composites

Bioactivity of Green Synthesised Silver Nanoparticles

Phytochemicals as Synthesis Agents

By: Amandeep Kaur,Devinder Singh

Bachelor Thesis from the year 2013 in the subject Biology - Miscellaneous, grade: M.Sc., , course: Biotechnology, language: English, abstract: Research and analysis of nanoparticles (NPs) synthesis and their biological activities has been expanded significantly in the recent years. The agents used for nanoparticles (NPs) synthesis are of organic (mainly carbon) and inorganic (metal ions like silver and gold) origin (Singh et al., 2010). Among these, silver (Ag) is the most preferred NPs synthesis agent due to its reported use in medical field as best topical bactericides from ancient times (Lavanya et al., 2013). The stable silver nanoparticles had been synthesized by using soluble starch as both the reducing and stabilizing agents (Shrivastava et al., 2012). So the concern of scientific community shifted towards ecofriendly, natural and cheaper method of NPs synthesis by using microorganisms and plant extracts (Mohanpuria et al., 2008). The use of plant materials for silver nanoparticles (AgNPs) is most popular due to its potential biological activities, easy availability and faster rate of synthesis there by cutting the cost of NP's synthesis (Huang et al., 2007 and Salam et al., 2012). The nanoparticles had been clinically used for infection, vaccines and renal diseases (Malhotra et al., 2010). The plant extract of petals of herbal species like Punica granatum, Datura metel (Chandran et al., 2011) and stem extracts of Svensonia hyderobadensis (Linga et al., 2011) had been effectively used for AgNPs synthesis and investigated for their antimicrobial activities. Nanoparticles could be synthesized by various approaches like photochemical reactions in reverse micelles (Taleb et al., 1997), thermal decomposition (Esumi et al., 1990), sonochemical (Zhu et al., 2000) and microwave assisted process (Santosh et al., 2002 and Prasher et al., 2009). Nanocrystalline silver particles have found tremendous applications in the field of high sensitivity biomolecular detection and diagnostics (Schultz et al., 2000), antimicrobials and therapeutics (Rai and Yadav., 2009 and Elechiguerra et al., 2005) and micro-electronics (Gittins et al., 2000). Acacia auriculiformis A. Cunn. is an exotic species that can survive in degraded lands in Thai savanna (Badejo et al., 1998). Besides its high adaptability in degraded savanna areas, A. auriculiformis is known for its nitrogen fixation property (Sprent and Parsons, 2000) enriching macrofaunal composition (Mboukou-Kimbatsa et al., 1998), low allelopathic effects (Bernhard-Reversat et al., 1999) and ability to pump nutrients from the subsoil (Kang et al., 1993).

In Pursuit of Probity

The holy grail of governance

By: Devinder Singh Bagga

“Honesty is your biggest strength and Dignity your strongest defence.” Those are the simple yet profound words of an IAS officer who, from a humble background, rose to the highest echelons of the Government of India with a relentless focus on establishing the highest standards of ethical governance and moral rectitude. Devinder Singh Bagga was a man who believed that the administrative service is a tapasya—a self-effacing occupation to serve the masses. In his memoirs spanning thirty-seven years, he endeavours to narrate an administrator’s struggle to exercise administrative rectitude and probity while he navigated choppy waters with no patronage or protection. He held coveted positions in the Indian bureaucracy, including that of the Deputy Election Commissioner of India under the iconic T. N. Seshan, an era that transformed the Election Commission of India into a no-nonsense autonomous constitutional body. He eventually retired after becoming the Chief Secretary of India’s most challenging state—Uttar Pradesh. The author brings to life his experience of the “steel frame of India” and helps us get a deeper understanding of the various subjects that may yet be shrouded in conjecture and not fully understood by the layperson. Through this light-hearted, yet thoroughly insightful, account of his remarkable journey, the author conveys his views on what it takes to deliver exceptional administrative governance with objectivity and integrity while refusing to be drawn into contentious distractions “A very informative and interesting read from a man who fondly imagined in his ambitious moments that probity and determination are measuring instruments whose Zero Error is Zero.” – Kavita Bagga (a daughter’s fond remembrance)
