An Overview of ChemSpider, A Structure Based Community for Chemists, and Chemmantis, a Markup System for Chemistry Documents

submitted by: AntonyWilliams

This is a presentation I gave at Drexel University regarding our development of the ChemSpider and ChemMantis platforms. ChemSpider is built with the intention of providing a structure centric community for chemists and ChemMantis is to mark up and integrate chemistry based documents to online resources.

iSchool Open Notebook Science Talk

submitted by: jcbradley

This talk covers Open Notebook Science from an information technology perspective. It was presented by Jean-Claude Bradley at the Drexel iSchool on November 11, 2008. Although solubility measurements and chemical reactions are mentioned the focus is more on how information is stored, retrieved and used using free and hosted services such as Blogger, GoogleDocs, Wikispaces, ChemSpider, CDD and others. The UsefulChem project and the Open Notebook Science Challenge are highlighted.

Magnetic Warp (Singularity)

submitted by: SirZerp
This investigation describes and demonstrates a novel technique for the visualization of magnetic fields. Two ferrofluid Hele-Shaw cells have been constructed to facilitate the imaging of magnetic field lines. We deduce that magnetically induced photonic band gap arrays similar to electrostatic liquid crystal operation are responsible for the photographed images and seek to mathematically prove the images are of exact dipole nature. This is the ring magnet singularity version. All Rights...

Sources of Fecal Indicator Bacteria in Urban Streams and Ocean Beaches, Santa Barbara, California; Fecal indicator bacteria (FIB) concentrations in urban streams and ocean beaches in Santa Barbara, Calif. can exceed water-quality standards for recreational water. During low flow, high FIB concentrations in urban streams were associated with point discharges from storm drains, and concentrations in urban streamflow varied three-fold over the course of a day as a result of small variations in...
