As a new mom, Jessica Alba wanted to create the safest, healthiest environment for her family. But she was frustrated by the lack of trustworthy information on how to live healthier and cleaner--delivered in a way that a busy mom could act on without going to extremes. In 2012, with serial entrepreneur Brian Lee and environmental advocate Christopher Gavigan, she launched The Honest Company, a brand where parents can find reliable information and products that are safe, stylish, and affordable. The Honest Life shares the insights and strategies she gathered along the way.
The Honest Life recounts Alba's personal journey of discovery and reveals her tips for making healthy living fun, real, and stylish, while offering a candid look inside her home and daily life. She shares strategies for maintaining a clean diet (with favorite family-friendly recipes) and embraces nontoxic choices at home and provides eco-friendly decor tips to fit any budget. Alba also discusses cultivating a daily eco beauty routine, finding one's personal style without resorting to yoga pants, and engaging in fun, hands-on activities with kids. Her solutions are easy, chic, and down-to-earth: they're honest. And discovering everyday ways to live naturally and authentically--true to you--could be honestly life-changing.
Nickel, cobalt and platinum group metals are key elements for materials processing. They occur together in one book because they (i) map together on the periodic table (ii) occur together in many ores and (iii) are natural partners for further materials processing and materials manufacturing. They all are, for example, important catalysts – with platinum group metals being especially important for reducing car and truck emissions. Stainless steels and CoNiFe airplane engine super alloys are examples of practical usage.
The product emphasises a sequential, building-block approach to the subject gained through the author’s previous writings (particularly Extractive Metallurgy of Copper in four editions) and extensive experience. Due to the multiple metals involved and because each metal originates in several types of ore – e.g. tropical ores and arctic ores this necessitates a multi-contributor work drawing from multiple networks and both engineering and science.Synthesizes detailed review of the fundamental chemistry and physics of extractive metallurgy with practical lessons from industrial consultancies at the leading international plantsDiscusses Nickel, Cobalt and Platinum Group Metals for the first time in one bookReviews extraction of multiple metals from the same tropical or arctic oreIndustrial, international and multidisciplinary focus on current standards of production supports best practice use of industrial resources
Organic Synthesis: The Disconnection Approach, 2nd Edition introduces this important technique, to help students to design their own organic syntheses. There are forty chapters: those on the synthesis of given types of molecules alternate with strategy chapters in which the methods just learnt are placed in a wider context. The synthesis chapters cover many ways of making each type of molecule starting with simple aromatic and aliphatic compounds with one functional group and progressing to molecules with many functional groups. The strategy chapters cover questions of selectivity, protection, stereochemistry, and develop more advanced thinking via reagents specifically designed for difficult problems.
Examples are drawn from pharmaceuticals, agrochemicals, natural products, pheromones, perfumery and flavouring compounds, dyestuffs, monomers, and intermediates used in more advanced synthetic work. Reasons for wishing to synthesise each compound are given.
This second edition has been fully revised and updated with a modern look. Recent examples and techniques are included and illustrated additional material has been added to take the student to the level required by the sequel, “Organic Synthesis: Strategy and Control”.
Several chapters contain extensive new material based on courses that the authors give to chemists in the pharmaceutical industry.
Organic Synthesis: The Disconnection Approach, 2nd edition provides a full course in retrosynthetic analysis for chemistry and biochemistry students and a refresher for organic chemists working in industry and academia.
