Physics & Toxicology @ ScienceIndex.com
Mannheim, Germany (PRWEB) March 13, 2012
ScienceIndex.com is a Web 2.0 sciences social network established in 1998 to index the very latest news, headlines, references and resources from science journals, books and websites worldwide. The site covers news in all fields of biology, business, chemistry, engineering, geography, health, mathematics and society. In the field of Chemistry, the site has now included the two new categories Physics and Toxicology. While the Physics category covers properties, interactions, processes, and laws of matter and energy, the Toxicology category covers the nature, effects, and detection of poisons and the treatment of poisoning.
ScienceIndex.com's Chemistry Sciences Category covers the composition, structure, properties, and reactions of substances. Its seven subsections include Biochemistry, Food, Inorganics, Materials, Organics, Physics and Toxicology. Users can receive alerts if new content has been posted in this category by subscribing to ScienceIndex.com's Chemistry Sciences RSS feed.
ScienceIndex.com's Physics category covers properties, interactions, processes, and laws of matter and energy. It currently contains nearly 65,000 articles partly derived from nearly 200 scientific journals. The latest articles in this category are also available through a Physics RSS feed. One of the latest additions covers optofluidic surface enhanced Raman spectroscopy (SERS) for synergizing photonics and microfluidics for chemical and biological analysis. SERS leverages the specificity of Raman scattering and the sensitivity provided by localized plasmonic effects for applications in chemical and biomolecular detection while optofluidic SERS which is the synergistic use of microfluidics to improve the performance of SERS, may finally lead to practical devices for chemical and biomolecular detection. The authors describe recent advances in optofluidic SERS microsystems that have been developed to improve the performance and applicability of SERS, project future advances in optofluidic SERS, and present a vision for the disruptive technologies that will enable the translation of SERS from the research lab to practical uses. Another newly included story presents a comprehensive review of numerical methods and models for interface resolving simulations of multiphase flows in microfluidics and micro process engineering. It also reviews applications of the methods in microfluidics and micro process engineering, including flow hydrodynamics (separated and segmented flow, bubble and drop formation, breakup and coalescence), heat and mass transfer (with and without chemical reactions), mixing and dispersion, Marangoni flows and surfactants, and boiling.
ScienceIndex.com's Toxicology category covers the nature, effects, and detection of poisons and the treatment of poisoning. It currently contains nearly 6,000 articles partly derived from 20 scientific journals. The latest articles in this category are also available through a Toxicology RSS feed. One recently included article in this category assesses hair testing for cocaine and metabolites by GC/MS as criteria to quantitatively assess cocaine use. The authors developed and validated a simple, rapid and sensitive method for the determination of cocaine and its main metabolites (benzoylecgonine and cocaethylene) in human hair. The method involved solid-phase extraction with an Oasis HLB extraction cartridge and subsequent analysis by GC/MS and was applied to 40 hair samples from self-reported cocaine users arrested by the police who provided a positive urine-analysis for cocaine. The method was demonstrated to be suitable for its application in forensic toxicology.
ScienceIndex.com currently contains over 1.4 million stories distributed among 75 categories. 75,370 users monitor nearly 8,400 journals covering the broad spectrum of sciences. They share circa 2,500 new articles every day. Since new science content is discovered in real-time, the delay between original publication and appearance at ScienceIndex.com is no more than two days. ScienceIndex.com provides an advanced search feature which suggests up to ten closely related articles for a search and also for a selected story. Other features include a "Life Traffic Feed", a "Top Content" sidebar, Google Translate functionality, and RSS feeds for every category. ScienceIndex.com also maintains the new Twitter account @ScienceIndex_.
