Animation of GC solvent focusing
This site has very good animations related to separations. It deals specifically with solvent focusing in gas chromatography. The animations are short (one to two minutes) and can easily be shown in class as part of a lecture. They are extremely helpful in illustrating key components and concepts of chromatographic systems. Users are encouraged to explore the site and the other brief animations as well. Separate links to other simulations by the same company (TRSL) are also listed on ASDL.
GC coating animation
This site is one in a series of sites with very good animations related to separations. This animation deals specifically with solute retention in GC. The animations are short (one to two minutes) and can easily be shown in class as part of a lecture. They are extremely helpful in illustrating key components and concepts of chromatographic systems. Users are encouraged to explore the site and the other brief animations as well. Separate links to other simulations by the same company (TRSL) are a
Photodetectors and Fiber Optics
Power point slides to support a lecture on the principles and usage of photodiodes and optical fibers for sensors and instrumentation. There is no supporting text for the slides.
Introduction to Dynodes
This site is presented as a guided exploration into the operation of a photomultiplier from the first light incidence to the output signal. Questions guide the exploration and allow (sometimes require)the student to speculate on the result before going forward. A careful, patient student will get a thorough introduction to the operation of a dynode and how to bias it.
RSC.org: Proton NMR
This video, distributed on YouTube by the Royal Society of Chemistry is on the basic principles of NMR. This video is a good primer and would be very useful to supplement introductory lectures on NMR. The video covers the basic theory behind a 1H spectrum and goes through actually acquiring a spectrum. The top-off look of the instrument is useful and how the superconducting magnet is mounted. Good for a basic introduction.
Experiments in Electroanalytical Chemistry
This website offers educators a set of eight classical electroanalytical experiments suitable for use in a quantitative analysis, instrumental analysis, or electrochemistry course. The materials should be useful for advanced undergraduates and beginning graduate students. Experiments include coulometric, conductometric, and potentiometric titrations, stripping analysis, flow injection analysis, and polarography. It is important to note that several of the experiments use mercury or mercury co
Introduction to Lasers
Lasers are preferred light sources for high resolution or time-resolved optical spectroscopy. This module introduces the workings of lasers and gives examples of common designs.
A learning module focused on principles and practice of NMR for quantitative analysis, an application less commonly associated with the technique than is structure determination. Links to simulation packages are included.
Gas Chromatography Video
This is a high quality video module demonstrating the basics of gas chromatography. Highlights include different GC instruments, detectors etc., as well as unique topics such as trouble shooting and interfacing the column that are not addressed in standard texts. This resource can be run (Shockwave Flash) from the home server or downloaded to your computer.
Accelerator Mass Spectrometry in Biology and Health Care
This video, developed at Lawrence Livermore National Laboratory, describes the instrumentation for accelerator mass spectrometry and its applications. The video describes the instrumentation and its application for carbon dating and measurements of drug distribution.
Green Chemistry (2nd edition)
Measurement science used to characterize environmentally important species is a central aspect of this textbook and accompanying lecture support/PowerPoint presentations. In addition to discussing the hows and whys of measurement, the discussion of measurements up to 2007 as related to the future of the environment provides a context for learning the material.
primer on microscopes
This website is sponsored by Olympus company. It is similar to two other sites (one by Florida State University, the other by Nikon) already in asdlib whereby a common group of authors contributed to the development of all three sites. Thus, these sites are similar in content although differences exist. This Olympus site has a \"virtual microscopy\" that contains links to interacdtive tutorials that demonstrate the operation of different types of microscopes. Thus, one can compare how various
NIST Engineering Statistics Handbook
This site provides a comprehensive electronic handbook on statistics for scientists and engineers. Topics include graphical approaches for exploratory data analysis, the characterization of measurement processes, the construction of statistical models for predicting and/or optimizing process, experimental design, process control monitoring, significance testing and the evaluation of product reliability. Although the site may be too detailed and complex for an undergraduate student to navigate wi
Cooperative Learning, Values, and Culturally Plural Classrooms
This webpage provides an introduction to cooperative learning by David and Roger Johnson who developed the technique. The article provides an overview of the cooperative learning method, discusses its educational benefits, and provides assessment data for its efficacy. The article also provides archival references to their work and others. As such the article is an invaluable resource for faculty interested in developing and implementing cooperative learning activities in their own classrooms
RCSB Protein Data Base
This website is an "Information Portal To Biological Macromolecular Structure". It is a protein data bank that contains a very large structural database in addition to providing a variety of tools and resources for studying the structure of biological macromolecules and their relationships to sequence, function and disease. A good starting point is to take the tutorial which explains how to use the site and its contents. This site contains meritorious information on biological macromolecules an
Bragg's Law and Diffraction
This site presents an introduction to Bragg\'s Law of Diffraction, along with how diffraction of x-rays provides information on atoms in crystalline material. An Applet allows the user to vary the wavelength and angle of incidence of radiation to a surface, along with the distance between layers of the material to demonstrate the conditions necessary for constructive interference, or a Bragg\'s condition. The derivation of Braggs law is also explained.
Asking the right question
This RLO outlines why asking the right question can help in the search for evidence, and explains how to construct good questions using the PICO technique.

Episode 14, Part 2 "First Person Victim: Using Interactive Drama and Tragedy to Create Awareness about The Consequences of War". This video of our March 31st, 20101 research meeting will feature our friend Henrik Schønau Fog, PhD Fellow in Mediology who will present his game First Person Victim, a project that he developed with a team of other researchers from Aalborg University, which situates the player in the middle of a war scenario as a civilian. It's a fascinating project, so don't mis
4 How Darwin has influenced others The link below will take you to a timeline of psychologists. If you scroll down the list of people in the left-hand column and click on Darwin's name you will see from the link how influential Darwin’s work was on others that followed, for example Freud, Pavlov, Dawkins. Read some background on Darwin from this page and then you may wish to click on the other people highlighted on this page to see the relevance and impact on their work, theories and ideas from Darwin’s original theory.
