Method and device for analyzing chemical substances

A method for analyzing a sample on a mass spectrometer, wherein the sample is electrochemically treated before being assigned to a mass spectrometer, whereby molecular structure-related information (structural information) can be constantly obtained from fragment ions measured by a mass spectrometer to thereby provide a high-accuracy analyzing method in terms of specificity and sensitivity.

Methods and structure for automated active pharmaceuticals development

Methods and associated structures for integrating molecule database information and chemical synthesis database information to generate a project synthesis plan shared by multiple entities within a chemical development service provider enterprise. The shared information is used by various management, R&D and financial entities within such an enterprise. Shared use of common data improves accuracy of the data used by each such entity and reduces need for error-prone human intervention in generating and manipulating relevant data.

Intermediate precursor compositions used to make supported catalysts having a controlled coordination structure and methods for preparing such compositions

Intermediate precursor compositions for use in manufacturing supported reactive catalysts having a controlled coordination structure, and methods for manufacturing such precursor compositions are disclosed. The precursor compositions include a catalyst complex formed from catalyst atoms and a control agent that is applied to a substrate. Reduction of the catalyst complex yields supported reactive catalyst in which a preponderance of the top or outer layer of atoms of the catalyst particles exhibit a controlled coordination number of 2. The supported catalysts are useful for a variety of chemical reactions, including the preparation of hydrogen peroxide with high selectivity.

System and method for identifying similar molecules

A vectorization process is employed in which chemical identifier strings are converted into respective vectors. These vectors may then be searched to identify molecules that are identical or similar to each other. The dimensions of the vector space can be defined by sequences of symbols that make up the chemical identifier strings. The International Chemical Identifier (InChI) string defined by the International Union of Pure and Applied Chemistry (IUPAC) is particularly well suited for these methods.

Generating intra-particle crystallographic parameter maps and histograms of a chemically pure crystalline particulate substance

Generating intra-particle crystallographic parameter maps and histograms of a chemically pure crystalline particulate substance. Spectral imaging, in general, and focus-fusion multi-layer spectral imaging, in particular, combined with pattern recognition and classification analysis are performed on individual particles for forming sets of single-particle spectral fingerprint data, characterized by single-particle spectral fingerprint spectra (FIG. 1). Spectral shifts are identified in the single-particle spectral fingerprint data, for forming intra-particle crystallographic region groups each featuring sub-sets of intra-particle spectral fingerprint pattern data, where selected data elements in each sub-set are shifted relative to corresponding data elements in remaining sub-sets in the same intra-particle crystallographic region group (FIG. 2). Each intra-particle crystallographic region group is associated with crystallographic parameters of crystal type and crystal class, for forming intra-particle crystallographic parameter data, used for generating intra-particle crystallographic parameter maps (FIG. 3) and histograms (FIG. 4) of the chemically pure crystalline particulate substance throughout a multi-particle sample.

Additive for activating iron electrodes in alkaline batteries

An additive for the iron electrodes of alkaline batteries which prevents and counteracts the tendency of iron electrodes to become passive and ineffective. The additive consists of sulfide, selenide or telluride which is sparingly soluble in the electrolyte and has a decomposition potential more electronegative than the final charging potential of the iron electrode. The additive may be placed in the active electrode material during manufacture but may also be placed in the battery during or after manufacture, for example in tablet form. The additive may also be introduced in a manner permitting subsequent activation by electrochemical methods. A number of examples is presented.
