Results of a study are presented which is concerned with the chemical properties of groups formed on carbon black surfaces by reactions with environmental substances. Carbon black appears to be covered with such functional groups as might be expected to result from the reaction of free radicals or highly strained unsaturated structures with gases ...

The potential to distinguish juvenile wild from cultured fishes and to discriminate among juvenile fishes by species based on fatty acid composition was demonstrated. Statistical approaches to data evaluation included analysis of variance, correlation analysis, principal component analysis (PCA), and quadratic discriminant analysis (QDA). Differences were ...

This presentation is a summary of results acquired over the last five years using the heats of interaction of a series of bases with various solid acids as a means for classifying them. A sulfonic acid resin provides a solid model for Broensted acidity. Silica is a model solid for hydrogen bonding interactions and ...

A hitherto undescribed black yeast was isolated from an extract of brown coal containing humic and fulvic acids at pH 0.6. The fungus showed morphological similarity to some members of the genus Exophiala (Chaetothyriales) and of Hortaea (Dothideales). Based on SSU rDNA sequence similarity to meristematic members of the Dothideales, ...

usefulness. Virus assembly Nodaviruses are simple nonenveloped RNA viruses with capsids formed from a single of the black beetle virus. (a) A schematic representation of the nodavirus capsid as a rhombic triacontahedron units. In the nodaviruses, the switch is a 10 base pair RNA duplex and a 12 amino acid polypeptide

Eumelanin was isolated from a sample of black, Indonesian human hair using three different published procedures: two different acid/base extractions and an enzymatic extraction. The morphology and spectroscopic properties of the isolated pigments differ significantly. The acid/base procedures both yield an amorphous material, while ...
