Many individuals have been involved in writing and reviewing materials for this project since it began at Richland High School in 1986, including contributions from educators at Northwest Regional Educational Laboratory, Central Washington University, the University of Washington, teachers from Northwest schools, and science and education personnel at Battelle, Pacific Northwest Laboratories. Support for development was also provided by the U.S. Department of Education. This latest version was revised during l993-1994 by a group of teacher consultants that included Guy Whittaker, Coupeville, Washington; Paul Howard, Richland Washington; Noel Stubbs and Eric Pittenger, Corvallis High School, Corvallis, Oregon; Andy Nydam, River Ridge High School, Lacey Washington; and Len Booth, Lacey, Washington. The following PNL staff members reviewed the guide: Mike Schweiger, Materials and Chemical Sciences Center, Irene Hays and Karen Wieda, Science Education Center; and Jamie Gority and Georganne O’Connor, Communications Directorate. Many other organizations and individu- als providing support are noted in the Acknowledgments section. The curriculum has also been endorsed by the U.S. Materials Education Council and was featured in articles in the MRS Bulletin, the journal of the Materials Research Society in September 1992 and December 1993.

  • Materials Science
    Materials Science Materials Science is an interdisciplinary field combining physics (fundamental laws of nature), chemistry (interactions of atoms) and biology (how life interacts with materials) to elucidate the inherent properties of basic and complex systems. This includes optical (interaction with light), electrical (interaction with charge), magnetic and structural properties of everyday electronics, clothing and architecture. The Materials Science central dogma follows the sequence: Structure—Properties—Design—Performance. This involves relating the nanostructure of a material to its macroscale physical and chemical properties. By understanding and then changing the structure, material scientists can create custom materials with unique properties. The goal of the materials science minor is to create a cross-disciplinary approach to fundamental topics in basic and applied physical sciences. Students will gain experience and perspectives from the disciplines of chemistry, physics and biology. The minor places a strong emphasis on current nanoscale research methods in addition to the basics of electronic, optical and mechanical properties of materials. Any student with an interest in pursuing the cross-disciplinary minor in materials science should consult with the coordinator of the minor. Students are encouraged to declare their participation in their sophomore year but no later than the end of the junior year. Students also should seek an adviser from participating faculty.

  • TSCA Inventory Representation for Products Containing Two Or More
    mixtures.txt TOXIC SUBSTANCES CONTROL ACT INVENTORY REPRESENTATION FOR PRODUCTS CONTAINING TWO OR MORE SUBSTANCES: FORMULATED AND STATUTORY MIXTURES I. Introduction This paper explains the conventions that are applied to listings of certain mixtures for the Chemical Substance Inventory that is maintained by the U.S. Environmental Protection Agency (EPA) under the Toxic Substances Control Act (TSCA). This paper discusses the Inventory representation of mixtures of substances that do not react together (i.e., formulated mixtures) as well as those combinations that are formed during certain manufacturing activities and are designated as mixtures by the Agency (i.e., statutory mixtures). Complex reaction products are covered in a separate paper. The Agency's goal in developing this paper is to make it easier for the users of the Inventory to interpret Inventory listings and to understand how new mixtures would be identified for Inventory inclusion. Fundamental to the Inventory as a whole is the principle that entries on the Inventory are identified as precisely as possible for the commercial chemical substance, as reported by the submitter. Substances that are chemically indistinguishable, or even identical, may be listed differently on the Inventory, depending on the degree of knowledge that the submitters possess and report about such substances, as well as how submitters intend to represent the chemical identities to the Agency and to customers. Although these chemically indistinguishable substances are named differently on the Inventory, this is not a "nomenclature" issue, but an issue of substance representation. Submitters should be aware that their choice for substance representation plays an important role in the Agency's determination of how the substance will be listed on the Inventory.

  • Chapter 2 the Solid Materials of the Earth's Surface
    CHAPTER 2 THE SOLID MATERIALS OF THE EARTH’S SURFACE 1. INTRODUCTION 1.1 To a great extent in this course, we will be dealing with processes that act on the solid materials at and near the Earth’s surface. This chapter might better be called “the ground beneath your feet”. This is the place to deal with the nature of the Earth’s surface materials, which in later sections of the chapter I will be calling regolith, sediment, and soil. 1.2 I purposely did not specify any previous knowledge of geology as a prerequisite for this course, so it is important, here in the first part of this chapter, for me to provide you with some background on Earth materials. 1.3 We will be dealing almost exclusively with the Earth’s continental surfaces. There are profound geological differences between the continents and the ocean basins, in terms of origin, age, history, and composition. Here I’ll present, very briefly, some basic things about geology. (For more depth on such matters you would need to take a course like “The Earth: What It Is, How It Works”, given in the Harvard Extension program in the fall semester of 2005– 2006 and likely to be offered again in the not-too-distant future.) 1.4 In a gross sense, the Earth is a layered body (Figure 2-1). To a first approximation, it consists of concentric shells: the core, the mantle, and the crust. Figure 2-1: Schematic cross section through the Earth. 73 The core: The core consists mostly of iron, alloyed with a small percentage of certain other chemical elements.

Auble, M.A. University of Nebraska, 2011 Adviser: Carole Levin Sixteenth and seventeenth century sources reveal that precious stones served a number of important functions in Elizabethan and early Stuart society. The beauty and rarity of certain precious stones made them ideal additions to fashion and dress of the day. These stones also served political purposes when flaunted as examples of a country‘s wealth, bestowed as favors, or even worn as a show of royal support.

Pokatilov Laboratory of Physics and Engineering of Nanomaterials, Department of Physics and Engineering, Moldova State University, Chisinau, MD-2009, Republic of Moldova 3Quantum Seed LLC, 1190 Columbia Avenue, Riverside, California 92507 USA Abstract We review thermal properties of graphene and few-layer graphene, and discuss applications of these materials in thermal management of advanced electronics. The intrinsic thermal conductivity of graphene – among the highest of known materials – is dominated by phonons near the room temperature. The examples of thermal management applications include the few-layer graphene heat spreaders integrated near the heat generating areas of the high-power density transistors. It has been demonstrated that few-layer graphene heat spreaders can lower the hot-spot temperature during device operation resulting in improved performance and reliability of the devices. Keywords: graphene, thermal conductivity, heat spreaders, thermal management 1 Zhong Yan, Denis L. Nika and Alexander A. Balandin (invited review, submitted in 2014) I. Introduction Thermal management represents a major challenge in the state-of-the-art electronics due to rapid increase of power densities [1, 2]. Efficient heat removal has become a critical issue for the performance and reliability of modern electronic, optoelectronic, photonic devices and systems.
