What do you think of when you think of crystals? You might think of rich jewels or you may think of a hotel chandelier? Well you would be surprised at how many other things in the world are classed as crystals. Certain substances such as salt, sugar and snow are all classed as crystals.Crystals and Crystal Growing For Children: A guide and introduction to the science of crystallography and mineralogy for kids. This guidebook covers basic chemistry and physics that form the fundamentals behind the art and science of growing crystals.
This is the first-ever textbook on the fundamentals of nucleation, crystal growth and epitaxy. It has been written from a unified point of view and is thus a non-eclectic presentation of this interdisciplinary topic in materials science. The reader is required to possess some basic knowledge of mathematics and physics. All formulae and equations are accompanied by examples that are of technological importance. The book presents not only the fundamentals but also the state of the art in the subject. The second revised edition includes two separate chapters dealing with the effect of the Enrich-Schwoebel barrier for down-step diffusion, as well as the effect of surface active species, on the morphology of the growing surfaces. In addition, many other chapters are updated accordingly. Thus, it serves as a valuable reference book for both graduate students and researchers in materials science.
Do you worry that you're messing up your kids? Do you get stressed when you think about their futures? New York Times bestselling author Crystal Paine knows how you feel.

Crystal Children reflect the new generation that has come to the Earth plane after the Indigo Children. They are approximately ages 0 through 5, although some members of the first wave of Crystal Children are as old as 7. These children are like Indigos—highly psychic and sensitive—but without the dark edge and the anger energy. The term Crystal Children is already taking hold worldwide, and people everywhere are talking about these special kids. Since Doreen is the only researcher who is publicly giving speeches on the subject, her audiences have been asking her for a book on the topic. It’s a natural sequel to her book The Care and Feeding of Indigo Children. As babies, Crystal Children may take longer than normal to begin talking. They are highly telepathic, and their tuned-in mothers communicate with them nonverbally. Because they’re so sensitive, the Crystal Children babies may fuss and cry a lot in crowded places. They’re also very fond of nature. Doreen once watched one Crystal Child walk from tree to tree, giving each one a big hug. Crystal Children are beautiful inside and out, like magnificent little high-priests and priestesses. One look in their eyes, and you’ll recognize Divine love and wisdom. Their auras are bright, radiant, and opalescent—they seem to glow from the inside! They talk about past lives, distant galaxies, and profound insights concerning peace and love. Most Crystal Children’s parents are aware that their kids are special, and they’re thrilled to be parenting such delightful children. The book includes many interviews with Crystal Children, their parents, and teachers. It discusses parenting and teaching methods that are essential to keeping these children happy and healthy, and how to avoid pitfalls that could spoil their special gifts.
Since the first publication of this definitive work nearly 40 years ago, this fourth edition has been completely rewritten. Crystallization is used at some stage in nearly all process industries as a method of production, purification or recovery of solid materials. Incorporating all the recent developments and applications of crystallization technology, Crystallization gives clear accounts of the underlying principles, a review of the past and current research themes and guidelines for equipment and process design. This new edition introduces and enlarges upon such subjects as: Control and Separation of polymorphs and chiral crystals Micro- and macro-mixing and the use of computer fluid dynamics Seeding and secondary nucleation in batch crystallization processes Incorporation of upstream and downstream requirements into design procedures for crystallization plant Computer-aided molecular design and its use in crystal habit modifier selection Crystallization provides a comprehensive overview of the subject and will prove invaluable to all chemical engineers and industrial chemists in the process industries as well as crystallization workers and students in industry and academia. Crystallization is written with the precision and clarity of style that is John Mullin's hallmark - a special feature being the large number of appendices that provide relevant physical property data. Covers all new developments and trends in crystallization Comprehensive coverage of subject area
