Made to Measure : New Materials for the 21st Century
Made to Measure introduces a general audience to one of today's most exciting areas of scientific research: materials science.Philip Ball describes how scientists are currently inventing thousands of new materials, ranging from synthetic skin, blood, and bone to substances that repair themselves and adapt to their environment, that swell and flex like muscles, that repel any ink or paint, and that capture and store the energy of the Sun.He shows how all this is being accomplished precisely because, for the first time in history, materials are being "made to measure": designed for particular applications, rather than discovered in nature or by haphazard experimentation.Now scientists literally put new materials together on the drawing board in the same way that a blueprint is specified for a house or an electronic circuit.But the designers are working not with skylights and alcoves, not with transistors and capacitors, but with molecules and atoms. This book is written in the same engaging manner as Ball's popular book on chemistry, Designing the Molecular World, and it links insights from chemistry, biology, and physics with those from engineering as it outlines the various areas in which new materials will transform our lives in the twenty-first century.The chapters provide vignettes from a broad range of selected areas of materials science and can be read as separate essays.The subjects include photonic materials, materials for information storage, smart materials, biomaterials, biomedical materials, materials for clean energy, porous materials, diamond and hard materials, new polymers, and surfaces and interfaces.

Rethinking Coal : Chemicals and Carbon-Based Materials in the 21st Century
Rethinking Coal: Chemicals and Carbon-Based Materials in the 21st Century is a timely presentation of the current uses and future impacts of coal and coal technologies. Three decades ago, coal was the dominant source of electricity generation in the U.S. and the recipient of moderate research efforts in the synthetic fuels arena.In recent years, though coal is still heavily discussed in the media, the focus has shifted towards the ill effects that coal mining and combustion have on the environment.As it is likely that we will have to rely on coal for a major share of electricity generation for decades to come, it is increasingly important to understand the current issues that surround coal, as well as future prospects for developing or applying coal technologies that have lesser impacts on the environment.In this book, author Harold Schobert discusses the current uses and future impacts of coal and coal technologies.Rethinking Coal: Chemicals and Carbon-Based Materials in the 21st Century provides an overview of how coal formed eons ago; the basic properties of coal and differences among the many kinds of coals; the ways coal is currently used in the world; new and emerging technologies for using coal, including prospects for using coal as a source of valuable chemicals and carbon materials rather than burning it; and the impacts of coal use on the environment including CO2 emissions and global climate change, as well as the various practices of coal mining.Rethinking Coal presents the environmental, technical, and economic advantages and disadvantages of various applications of coal, without disparaging or supporting its use.

When is the 21st week?
The 21st week of the year typically falls in May or June, depending on when the year starts. In a standard calendar year starting in January, the 21st week would be around the end of May. This is a little over halfway through the year, making it a good time to reflect on the progress of the year so far and plan for the remaining months.

How do you find the 21st?
To find the 21st of something, you simply count to 21. For example, if you are looking for the 21st day of the month, you would count each day until you reach the 21st. Similarly, if you are looking for the 21st item in a list, you would count each item until you reach the 21st. It's a straightforward process of counting and identifying the 21st in a sequence.
