Nonlinear Studies of Coronal Heating by the Resonant Absorption of Alfven Waves
A series of animations showing various quantities from a coronal heating simulation
Quality in Environmental Analysis
Although this website by the U.S. Geological Survey (USGS) does not contain analytical data or methods per se, it is one that contains a complete compendium of links to material on environmental topics under the pervue of USGS. As such, it can serve as a resource and background material for students, faculty or practitioners interested in learning about environmental issues. For example, there is a link to Hg in the environment that discusses the sources, chemical composition and consequence o
Introduction to Capillary Chromatography
This site discusses many of the details in how ro convert a traditional HPLC system into a capillary HPLC system. Included in the discussion is how to use splitting to get to the lower flow rates required and how to pack your own capillary LC columns. There is detailed information on how to go about plumbing these sorts of systems (use of fittings, etc.), which may be valuable to someone who doesn't have that experience. The site also includes links to purchasing the components necessary for per
LC Calc (TM) Online. A handy calculator for HPLC computations.
This site contains several on-line calculators for use in liquid chromatography. These include pressure unit conversion, buffer pH, and scale-up factors. Some links may be broken.

Exploitation of Croquet CVE Platform for supporting Collaborative e-Learning Environments
This paper reviews the features of five 3 dimensional networked virtual environments which support collaborative learning applications, through the comparison of the tools and services they offer. Following that, we justify our choice of platform, which is the Croquet platform, and discuss design and implementation issues. Finally we present the results of the evaluation process of the virtual environment we developed, which consisted of the participation of twelve postgraduate students who comp

SSPD_Chapter 6_Part 7_Introduction to ATHENA 5 deals with specification of electrodes and saving the structure file.
Active Learning in Advanced Analytical Chemistry, a course for first year graduate students
The introductory lecture course for graduate-level analytical chemistry is commonly understood to require students to be broadly aware of analytical tools, current problems, and methods for linking problems and measurements. This article describes an active learning approach to this course, using review articles to focus discussion and reveal gaps in student knowledge. Students give most of the course\'s lectures, with grades based on lectures, exams, and a term paper.
Chromatography Nomenclature and Definitions
This website gives the IUPAC approved definitions in the field of chromatography. It is critical for students to appreciate the importance of using standardized nomenclature and definitions.
Tunable Monochromator Movie
This Quick Time movie illustrates and describes to operation of a Czerny-Turner monochromator. The slits, mirrors, grating and grating scan are described in the production of a specific wavelength at the outlet slit. The movie is a companion to the double beam spectrometer animation.
RSC.org: Gas Chromatography
This video, distributed on YouTube by the Royal Society of Chemistry is on the basic principles of GC. This video is a short primer (~5 min) which introduces the technique and instrumentation. There are many assumptions that are made in the presentation of this material, due to the fact the video is meant to be a basic introduction. Examples of such assumptions include the statement that volatility solely controls the elution order of volatile compounds on a GC column and that concentration
RSC.org: Mass Spectrometry
This video, distributed on YouTube by the Royal Society of Chemistry is on the basic principles of mass spectrometry, using a magnetic sector instrument to demonstrate how specific m/z ratios can be selected. The theory and operation of MS, including the chemistry of ionization and fragmentation is described at an introductory level. There\'s also an excellent example of the use of high resolution MS to differentiate between nominal mass and actual mass. The video does a very good job of explain
Principal Component Analysis
This site provides an introduction to principal component analysis, beginning with a glossary of important terms before taking the reader through the process of completing a principal component analysis. One limitation to the site is its reliance on Minitab and SPSS for calculations. Users without access to these programs can reproduce the calculations using other software packages, such as the freeware program R. Prior knowledge of basic statistics is assumed; thus, the site is most appropriate
Simplex Optimization Methods
This site, from the developers of the software program Multisimplex, provides a basic introduction to simplex optimization. Topics include the basic simplex method, the modified simplex method and evolutionary optimization. Although the mathematical details are not included, the site provides flow charts showing the logic behind the optimization. The site assumes that the user understands the need for optimization and, therefore, is less suitable for beginners.
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
Basic Microscopy Concepts
The site provides introductory information related to optical microscopy. Among the topics addressed are resolution, numerical aperture, depth of field, field of view, illumination and the useful magnification range. A section on fluorescence microscopy is also included. Interactive video is used to demonstrate concepts in some cases. Researchers and educators interested in a brief overview of optical microscope principles may find the site useful.
