PowerMV Molecular Viewer PowerMV: A software environment for statistical analysis, molecular viewing, descriptor generation, and similarity search. Jack Liu, Jun Feng, Atina Brooks and Stan Young National Institute of Statistical Sciences Basic Functions: • Supports MDL SDF format • Displays molecules in multiple columns. • Displays properties contained in SD file in a table. • Anti-alias technology for best picture quality. • Table of molecule pictures and properties can be exported to Excel (Office XP and above) to generate personalized reports. • Calculates three types of binary atom pair descriptors and continuous weighed burden numbers. Calvin & Hobbes Search Engine - by Bing I have always been a big fan of Calvin & Hobbes comics, and their author, Bill Watterson. Since discovering the complete script online, as well as a collection of every daily strip on another website, I knew I could make the two reference each other and therefore create a "Calvin & Hobbes Search Engine" for lack of a better name. So I set out to do it. Currently the search only looks for EXACT phrases (not case sensitive), so if you're looking for a comic with the words "balloon" and "airplane" you cannot enter them both, or it will search for "balloon airplane" together. Perhaps in the future I will fix this, but it's actually a lot more difficult than leaving it as-is. There is one exception though!

HTML5 Chemistry Simulations With Java applets on the decline for many years. JavaScript, HTML5, and other scripting languages have managed to take over applets both in terms of browser support and extra functionality. At EDinformatics we are transitioning from Java, Shockwave and Flash to HTML5 Simulations which can easily be used on all platforms. Acid - Base Solutions How do strong and weak acids differ?

Chemistry Demonstrations, Experiments, Labs & Projects These are tutorials for performing your own chemistry demonstrations, laboratory exercises, projects, and chemistry experiments. Photos and movies are available for some chemistry demos. Chemistry Laboratory Safety RulesMake your chemistry laboratory experience safe by following these simple rules. How to Write a Lab ReportLab reports are an essential part of all laboratory courses and usually a significant part of your grade. If your instructor gives you an outline for how to write a lab report, use that. Here's a format for a lab report you can use if you aren't sure what to write or need an explanation of what to include in the different parts of the report.

PubChem Download Page This file contains the structures downloaded from the PubChem FTP site that have at least one assay result associated with them that was obtained in the context of the NIH Common Fund (previously: NIH Roadmap) Molecular Libraries Probe Production Centers Network (previously: Molecular Libraries Screening Center Network), part of the Common Fund’s Molecular Libraries and Imaging program . It is organized by unique chemical structures (“Compounds” in PubChem parlance), i.e. assay results for possibly multiple different samples (“Substances” in PubChem parlance) have been combined into the one record representing the unique chemical structure. Placeholder assays (assays containing a single record only) have been filtered out. Explanation of the property data fields in the SD file (note - properties present in the original PubChem files have been copied unchanged, for the explanation of those properties we point directly to the appropriate PubChem document ):

What chemical elements would look like if they were people We at Bright Side are certain that any subject, no matter how complicated, can be made interesting for children provided it’s explained in an accessible way. Take chemistry for example, which is often considered one of the toughest subjects for a child to learn at school. We suggest beginning with the most famous chemical elements and their characteristics. Illustrated by Lenya Brick for

Types of leaves To know more about "The leaves" According to the petiole: Petiolated leaves are those that have a petiole. This can be different in length from one plant to another. Sessile leaves do not possess a petiole. The blade expands itself directly from the stem. Chemical Reactions Chemical reactions are the processes by which chemicals interact to form new chemicals with different compositions. Simply stated, a chemical reaction is the process where reactants are transformed into products. How chemicals react is dictated by the chemical properties of the element or compound- the ways in which a compound or element undergoes changes in composition. Describing Reactions Quantitatively Chemical reactions are constantly occurring in the world around us; everything from the rusting of an iron fence to the metabolic pathways of a human cell are all examples of chemical reactions. Chemistry is an attempt to classify and better understand these reactions.

Une gigantesque base de données gratuite fournie par la société royale de chimie. On peut y retrouver toutes les caractéristiques et publications pour des millions de molécules. Ce serait un outil très utile pour les étudiants au les étudiants au cégep ou à l'université pour la préparation des laboratoires ou pour mener des projets (comme dans le cours d'intégration), notamment en chimie organique. by romainmartiny Feb 26
