Analytical Chemistry Techniques Manual
A set of four separate guides which provide introductions to the principles and practical application of different analytical chemistry techniques, illustrated with simple diagrams and photographs of equipment: (1) introduction to analytical chemistry, focusing on the analytical process, quality assurance and general laboratory techniques e.g. solution preparation; (2) introduction to molecular spectroscopy, including UV-Vis, fluorescence, IR, MS and NMR spectroscopy; (3) introduction to chroma
Fe, C 0.5 (wt%) steel, near a decarburised surface
This is a hypoeutectoid steel (one that has a carbon composition below that of the eutectoid). During original cooling from high temperature, some ferrite was formed first on the prior austenite grain boundaries and the remaining carbon-enriched austenite then transformed to pearlite in a eutectoid reaction. The specimen was then exposed to a decarburising atmosphere (just air in this case). This might happen inadvertently, or it could be done deliberately if a softer surface is required for som
Spherulite in poly-3-hydroxy butyrate (PHB)
Polymer melts often crystallise from heterogeneous nuclei to form ribbon-like lamellae, which have a folded chain molecular structure. They commonly radiate outwards from the nucleation point, to form spherical features called spherulites - which are often quite large. The characteristic Maltese cross pattern, seen when viewed between crossed polars, results from isoclinic fringes formed when one of the principal vibration directions is approximately parallel to the polariser. In some cases (inc
22.00J Introduction to Modeling and Simulation (MIT)
Basic concepts of computer modeling in science and engineering using discrete particle systems and continuum fields. Techniques and software for statistical sampling, simulation, data analysis and visualization. Use of statistical, quantum chemical, molecular dynamics, Monte Carlo, mesoscale and continuum methods to study fundamental physical phenomena encountered in the fields of computational physics, chemistry, mechanics, materials science, biology, and applied mathematics. Applications drawn

Ten Simple Rules for Getting Published
The student council (http://www.iscbsc.org/) of the International Society for Computational Biology asked me to present my thoughts on getting published in the field of computational biology at the Intelligent Systems in Molecular Biology conference held in Detroit in late June of 2005. Close to 200 bright young souls (and a few not so young) crammed into a small room for what proved to be a wonderful interchange among a group of whom approximately one-half had yet to publish their first paper.
Virtual Textbook of Organic Chemistry
This virtual textbook allows for visualization of 3D-molecular models while teaching principles of Organic Chemistry.
"The Workers, Once Again, Seem to Have Fallen by the Wayside:" The Impact of September 11th on Airli
The economic impact of the September 11, 2001 terrorist attacks on the World Trade Center most immediately affected workers in the airline and tourist industries. The airlines, like much of the U.S. economy, were already experiencing an economic slowdown after the boom years of the late 1990s. Within weeks of the attack, airlines laid off tens of thousands of workers and threatened to lay off more. President George W. Bush and the U.S. Congress quickly responded, offering $5 billion in cash gran
The simulation program is based on the Nobel Prize winning Hodgkin-Huxley model for excitation of the squid axon. The program simulates an excised squid axon by applying stimuli or clamps after setting the environment of the axon, changing its properties, and/or adding drugs or toxins. By using the program tools, experiments can be developed that explore a variety of nerve properties, ranging from classical phenomena such as threshold, summation, refractory period, and impulse propagation to mo
This item addresses concepts such as: entropy, free energy, first law of thermodynamics, basic reaction kinetics.
General Biology Fall 2008
This course is a general introduction to cell structure and function, molecular and organism genetics, animal development, form and function.
Vinegar and baking soda
Vinegar is an acid. An acid has a pH less than 7. When baking soda is added to vinegar, bubbles are produced and gas is released. Fizzing, bubbling, and change in smell are all evidence of a chemical reaction. The amount of gas produced using baking soda as an indicator tells you the relative concentration ...
General Biology I
An integrated course stressing the principles of biology. Life processes are examined primarily at the molecular and cellular levels. Intended for students majoring in biology or for non-majors who wish to take advanced biology courses.
You can access the problems below via the Load Homework dialogue in the File menu of the Virtual Lab. They have been organized by concept and ranked by difficulty (A ranking of 1 denotes an easier problem; 5 is more challenging). Word files for these problems are provided so that you may edit and distribute the assignments in your classroom. The following types of problems can be found: Determining the Heat of Reactions in Aqueous Solution, Coffee, Coolant, Camping, ATP Reaction (Thermochemistry
Using Molecular Weight
A previous tutorial shows how to calculate the molecular weight of a substance from the atomic weights given. On this page, we use the molecular weight to convert between the macroscopic scale (grams of a substance) and the microscopic scale (number of molecules of that substance).
In this interactive activity from The University of Utah, examine the molecular mechanisms that affect the brains of mice on drugs. Learn how different drugs create different responses in the brain and alter the natural state of a mouse.
