The test chemistry is essentially based on color reactions, for example, redox reactions or complexation. Analytical effects can be detected not only visually, but also measured with portable devices. Most often the measured signal is transmission, diffuse reflectance, or luminescence. Some of the ...

2003). Much of this flow occurs at relatively low temperatures, far from volcanically activeseafloor spreadingcenters where new ocean floor is created. This “ridge-flank” circulation can be influenced by off-axis volcanic or tectonic activity, and byexothermic reactionsthat occur within the crust...
multiple chemical reactions, to all reactor configurations, and to all forms of rate expression. This text also . . . Describes reactor operations in terms of dimensionless design equations, generating dimensionless operating curves that depict the progress of individual chemical reactions, the ...
1. Apparatus for investigating fast chemical reactions by optical detection, said reactions being initiated in a chemical system by an external perturbation, said apparatus comprising means for performing said external perturbation, at least one light path, means for supporting a sample cell in said ...
Let’s start withthis classicfrom 1971 in theJournal of Organic Chemistry. A paper with the title ‘Comparative mobility of halogens in reactions of dihalobenzenes with potassium amide in ammonia’ doesn’t sound like it promises much in the way of literary sparkle, but take a look at how...
Quickly define atom-to-atom mappings for your reactions, and ChemDoodle will help check your work. Input and output of reaction atom-to-atom mapping is fully supported in ChemDoodle Documents, ChemDoodle JSON, ChemDraw CDX and CDXML, SMILES, and MDL RXN files. Balancing Complete reactions can...
Organic synthesis remains a challenge in small molecule drug design, sinking time in the design-make-test cycle and potentially limiting the complexity of chemical space being explored1,2. The challenge of synthesis planning lies in searching through myriad of possible reactions to find optimal routes...
These tungsten powders are proved to be produced by homogeneous reactions in gas phase near the substrate and adheres to the furnace inner wall as they move with the fluid. The presence of tungsten powders when depositing dense tungsten coatings indicates that the homogeneous reactions contribute ...
Fast chemical reactions in turbulent liquid flows are studied experimentally and computationally. Experiments are carried out for reactive mixing in order to obtain local mean and fluctuating concentrations. The experimental findings are used to test the performance of numerical models for turbulence, mixin...
