ReactionFlash vs PhotoMetrix

Want to refresh your memory on named chemical reactions before an exam or a group meeting? Get all the details with ReactionFlash(R) as a great way to learn named reactions, understand their mechanisms and view examples published in peer-reviewed literature. Designed and developed in consultation with Professor Dr. Erick M. Carreira of ETH Zürich, the app covers 1'266 named chemical reactions, by far the largest collection of Named Reactions. Professor Carreira has helped ensure that we have all the fundamental reactions that should be part of every chemist’s toolkit: from the best-known ones to the ones only Nobel Prize winners remember! The app is designed like a set of flash cards so it can be used as a learning tool as well as a reference. Each ‘card’ shows the reaction, its mechanism and examples from peer-reviewed, published literature. It also has a quiz mode that lets you test your knowledge. Linking into Reaxys enables you to find the most recent examples of each reaction, many with experimental details. Reaxys delivers experimental facts from the literature, enabling researchers to find the best synthetic routes and conditions.

Summary: - Learn named reactions - Review and understand mechanisms - Explore examples published in peer-reviewed literature - Take the ReactionFlash quiz and see how much you know If you need support, please contact us at reactionflash@elsevier.com.

This app employs Single Linear Correlation technics for univariate analysis and Principal Component Analysis (PCA) for multivariate exploratory analysis, including Partial Least Square Regression (PLS). The image data are acquired using the device main camera and photo album, both converted in RGB histograms. In addition, apart color channels of RGB, HSV, HSL and HSI systems are used during the univariate and multivariate processes. It is possible to send by e-mail the image data, analysis data and charts. In order to validate the obtained results, the same sets of data were tested using Microsoft Excel© and ChemoStat©. The results in both applications coincided in various combinations. This app calculates and plot: eigenvalues, eigenvectors, scores, loadings using Singular Value Decomposition in Multivariate Analysis. This app calculates and plot: slope (span), intercept (off-set) and regression (Pearson product-moment correlation coefficient) in Univariate Calibration Analysis. http://dx.doi.org/10.5935/0103-5053.20160182
