Leading Chapter

Most lead used by industry comes from mined ores ("primary") or from recycled scrap metal or batteries ("secondary"). Human activities (such as the former use of "leaded" gasoline) have spread lead and substances that contain lead to all parts of the environment. For example, lead is in air, drinking water, rivers, lakes, oceans, dust, and soil. Lead is also in plants and animals that people may eat. See Chapter 3 for more information on the physical and chemical properties of lead. Chapter 4 contains more information on the production and use of lead.

The lead chapter reviews the remarkable physical behaviors of a distinctive family of inter-metallic compounds - the filled lanthanide skutterudites. These unique compounds, which have the RM4X12 stoichiometry (where R = lanthanides, M = Fe, Ru, and Os, and X = I1, As and Sb), are best known for their excellent high temperature (> 700 K) thermoelectric properties. But as Brian Sales points out, they also exhibit a rich variety of electronic and...

Heating and melting metal was one of the first industrial uses of OEC and continues to be an important application today. OEC has been widely used in both large integrated steel mills as well as in smaller minimills. It has also been used in the production of nonferrous metals such as aluminum, brass, copper, and lead. Chapter 5 specifically concerns ferrous metals, while Chapter 6 discusses applications in nonferrous metals. 

Cadmium (Chapter 8) is one of the all-star pollutants, along with a few other elements such as mercury (Chapter 9), lead (Chapter 10), and arsenic (see Volume 44, below), and is of great toxicity to most living systems, including man. However, recently it has become apparent that cadmium is also a nutrient... 

Student Leadership Award This award is granted to someone with demonstrated leadership in terms of serving as chapter officers, leading chapter activities, interacting with university administration, and interacting with ASCE branches/sections. Candidates for this award must be nominated by the faculty or practitioner advisor, department head, or branch/section officers. 

Only a few compounds with Pb-P linkages are at present known. There appear to be no binary lead phosphides although Hittorfs phosphorus can be crystallised from molten lead (Chapter 4.1), and the phosphide HgPbPi4 is known (Figure 8.16). 

Each chapter in the volume authoritatively speaks for itself on an important topic. However, the reader is invited to enjoy the lead chapter by Ulrich Weiss who describes his role in the research on the shikimate pathway during 1952/53. We are grateful to Dr. Weiss for this charming account of his work carried out in the laboratory of Dr. B.D. Davis during that period. 

With respect to the order of chapters, it was suggested by professors who use the book that the chapters representing basics about the practice of safety be the leading chapters. So, the first four chapters are now On Becoming a Profession, Defining the Practice of Safety, Principles for the Practice of Safety A Basis for Discussion, and Academic and Skill Requirements for the Practice of Safety. ...

This volume contains 16 chapters by leading boron chemists worldwide. The book is organized into three sections based on the symposium. The lead chapter reviews the current status of organoborane chemistry, which is followed by chapters discussing stoichiometric and catalytic methods, as well as asymmetric methods and synthesis.
