Internet Scout Project
The "Earth Observing System (EOS) Aura is a NASA mission to study the Earth's ozone, air quality, and climate" by researching the composition, chemistry, and dynamics of the Earth's atmosphere. Visitors can learn how Aura is investigating three questions: Is the Earth's ozone layer recovering? Is air quality getting worse? How is Earth's climate changing? Researchers can find extensive details about the flight, spacecraft devices and specifications, and the data processing and validation. Visito
Lecture 18 - 11/30/2010
This introductory course in "Modern Biology" covers topics found in the fields of cellular biology, molecular biology, biochemistry, and genetics. It does not cover organismal biology or taxonomy. This course is a requirement for biology majors at Carnegie Mellon University. The course is carefully planned to provide the background biology students will need for advanced biology classes. Non-biology majors will also find this course useful as it explains many of the concepts and techniques curre
Molecular Stepping Stones
A molecular approach to biology must develop in students an understanding of molecules, their interactions and the consequences of these interactions. Biological phenomenon now more than ever rely on chemical and physical principles for molecular explanations of the phenomenon. We have selected 10 physical-chemical principles that underlie many biological processes: we call them "Molecular Stepping Stones." Below are links to entry level model-based activities for the Stepping Stones.
Amplification of Biochemical Signals: the ELISA Test
Students are introduced to the role of molecular shape, weak attractions and charge in biology and biochemistry, and then undertake a simulated Direct ELISA test.
6.701 Introduction to Nanoelectronics (MIT)
Traditionally, progress in electronics has been driven by miniaturization. But as electronic devices approach the molecular scale, classical models for device behavior must be abandoned. To prepare for the next generation of electronic devices, this class teaches the theory of current, voltage and resistance from atoms up. To describe electrons at the nanoscale, we will begin with an introduction to the principles of quantum mechanics, including quantization, the wave-particle duality, wavefunct
Fast Scan Voltammetry
A short presentation of theory and practice of electrochemistry focused on use of microelectrodes and micro-bands in flow cells. Problems encountered are addressed and response characteristics discussed.
Chemical Equilibria: The Law of Mass Action
Fundamental ideas and terminology of equilibria from a general chemistry perspective. A focus on closed systems, reversible chemical reactions, the law of mass action, Q and K. Also included are several multiple-choice questions that test the theories discussed. This site provides supplementary material that could be useful to beginning students in general and analytical chemistry.
Finance For New Ventures
The objectives of this course are to help students:Comprehend the process in which new business ventures are created; understand the financial aspects of the dynamics of the decision making process and day-to-day operations of a venture; become familiar with the various debt and equity sources of financing available to new and growing businesses; understand cash flow and pro forma logic and be able to apply the mechanics to income statement and balance sheet analysis and construction; apply econ
This site provides an excellent experiment involving cyclic voltammetry at a gold electrode. The experiment includes a detailed introduction to the topics of electrode capacitance, electrode reactions, and flux of the electroactive species to electrode surface. Lab report guidelines and post-lab questions are included.
GEM: Greener Education Materials for Chemists
This site is a resource for green chemistry principles and literature. It provides links for making green organic experiments and teaching the principles of green synthesis. Although it does not have many links specifically to chemical analysis, it provides an extensive overview and source of information regarding the important area of green chemistry.

Hardware demonstration and explanation of an inverted pendulum, stabilized by two independently controlled reaction wheels connected to DC motors. Made as part of a master's thesis at the System and Identification and Control Laboratory at the University of California, San Diego.
Virtual Textbook of Organic Chemistry
This virtual textbook allows for visualization of 3D-molecular models while teaching principles of Organic Chemistry.
Poverty and Elimination of Urban Health Disparities Challenge and Opportunity
The aim of this article is to examine the intersection of race and poverty, two critical factors fueling persistent racial and ethnic health disparities among urban populations. From the morass of social determinants that shape the health of racial and ethnic communities in our urban centers, we will offer promising practices and potential solutions to eliminating racial and ethnic health disparities.

Soil community analysis along a salt gradient using denaturing gradient gel electrophoresis of PCR-a
Many studies of hyper saline environments have been performed, mainly on aquatic systems. However, the microbial community in terrestrial thallasohaline environments has not been studied extensively. To our knowledge, this is the first study of a natural terrestrial thallasohaline environment using polymerase chain reaction (PCR) and denaturing gradient gel electrophoresis (DGGE). We studied the great salt plains (GSP) for this purpose. The GSP is a perfect example of an extreme environment. The
Reassessment of intra- and extra-ovarian expression of growth differentiation factor-9
Mammalian ovarian organogenesis is characterized temporally by oogonial mitosis, oogonial apoptosis, rescue of germ cells via interaction with somatic cells to form primordial follicles, and entrance into meiosis. Recent studies suggest that germ cell’s activity participate in this process via the production of local regulatory factors. Growth differentiation factor-9 (GDF-9), a novel transforming growth factor-family member, is expressed in ovaries of various species as a crucial factor in ov

Finite element modeling of energy absorption characteristic of hybrid structure - composite wrapped
The study of axial crush behavior of metal and composite tube has become a basis for the design of crashworthy structure in automotive and aircraft applications. Unlike metals, polymer composite material displays little or no plastic deformation characteristics. Research has showed that the hybrid tube usually made of inner aluminum tube over-wrapped with Eglass fiber reinforced epoxy have significantly higher energy absorption than either aluminum tube or composite tube. It is therefore importa
