An annotated bibliography of the Library of Congress' Chinese-English holdings on all subjects, as well as certain polyglot and multilingual dictionaries with English and Chinese entries. Included are general, encyclopaedic and comprehensive dictionaries; vocabularies; word lists; syllabaries; lists of place names, personal names, nomenclature,…

Complex behaviour associated with metamaterials can arise even in commonplace isotropic dielectric materials. We demonstrate how silver, for example, can support negative phase velocity and counterposition, but not negative refraction, at optical frequencies. The transition from positive to negative phase velocity is not accompanied by remarkable…

Evidence suggests that student engagement in the material they are studying correlates well with better learning outcomes, and instrumental analysis modules structured to reflect student interests are of wide significance. The analysis of levels of dietary (Cu, Fe, Mn, Zn) and undesirable (Cd and Pb) metals in commercially available and wild…

Electrocatalytic hydrogenation of acetol (IUPAC: 1-hydroxy-2-propanone), a species formed upon thermal liquefaction of biomass, can be achieved using inexpensive objects: filter paper, coins, batteries, salts, and water. This simple example demonstrates that "green" chemical transformations can be achieved with familiar items and helps…

Presented is a report of a program of the American Society for Metals, designed to introduce materials science principles via solid state chemistry into high school chemistry courses. At the time of the inception of this program in the mid-sixties, it was felt that high school students were not being adequately exposed to career opportunities in…

The present study focused on investigating the effectiveness of instruction via newly developed teaching materials based on cooperative learning when compared to a traditional approach, on ninth grade students' understanding of metallic bonding. Fifty-seven ninth grade science students from two science classes in the same high school participated…

This lesson explores the group of buildings in West Orange, New Jersey, built in 1887, that formed the core of Thomas Edison's research and development complex. They consisted of chemistry, physics, and metallurgy laboratories; machine shop; pattern shop; research library; and rooms for experiments. The lesson explains that the prototypes (ideas…

We describe a paper-based microfluidic device for iron(III) assay in an applied instrumental analysis laboratory. Simple and convenient devices were fabricated by the students using patterning of filter paper to investigate three different procedures: drawing a boundary with eyeliner or wax pen; drawing a boundary with waterproof permanent marker…

This document consists of materials for an 11-unit course on the following topics: (1) hacksawing; (2) filing and deburring; (3) locating centers for drilling; (4) cutting threads with tap and die; (5) using a hand reamer; (6) pedestal/bench grinder operation; (7) whetting, polishing, and lapping; (8) screw, drill, and tap extraction; (9) arbor…

The curriculum materials contained in this document were developed through a cooperative effort by educators in the state of Maryland. It was a curriculum project aimed at the meaningful integration of mathematics and science. It is suggested that these materials be used in two significant ways. First, this document can serve as an instructional…

A hands-on experiment to obtain atomic and ionic radii with lumps of metal and ionic compounds is reported here. The experiment is performed with industrial-grade typical metals (iron, copper, aluminum, and lead) and single-crystal lumps of ionic compounds (sodium chloride, potassium chloride, and potassium bromide). Students measure the dimension…

A unique, interdisciplinary collaboration between chemistry and classics has led to the development of an experiment for nonscience majors. This instrumental analysis experiment was designed for use in an archaeology course to quantify the amount of lead in ancient bronze coins. The coins were corroded beyond visual identification, so provenance…

This paper describes a method for determination of trihalomethanes (THMs) in drinking water via solid-phase microextraction (SPME) GC/MS as a means to develop and improve student understanding of the use of GC/MS for qualitative and quantitative analysis. In the classroom, students are introduced to SPME, GC/MS instrumentation, and the use of MS…

The focus of this article is the development of future science teachers. A research project, involving Cornell University, the Cornell Center for Materials Research, and NASCAR Champion Jeff Gordon is described. All research was conducted in association with faculty and staff at Cornell University and resulted in the development of a science…
