Insoluble organic matter (kerogen) constitutes a ma-jor portion of all organic matter in sediments. Many degradation studies, such as oxidation studies (Philp and Yang, ; Machihara and Ishiwatari, ) and pyrol-ysis studies (Philp et al., ; Sklarew, ), have shown the presence of polymethylene chains (- (CH 2) n-) in the kerogen.
Abstract. Most carbonate rocks contain insoluble residue to various extent, whereby the clay-content forms the basis for a classification of the limestones (Correns,p. ).Rocks with a clay mineral content of up to 25% are hereby designated as by: 1. The aim of this study was to prepare and characterize membranes of silk fibroin (SF) and chitosan (CHI) blends.
Moreover, a conformation transition of SF to a more stable form induced by the addition of CHI was verified. Blend membranes were prepared, after pH adjustment, in different ratios, and physical integrity, crystallinity, structural conformation and thermal stability were by: The ignited phosphate is References p.

The amount and size distribution of noncarbonate (insoluble) material in carbonate aggregates is of interest to those conducting research on the polish susceptibility of stone used in pavements or on the friction properties of pavement surfaces.
In addition, some agencies utilize the test for acceptance purposes to delineate carbonate aggregates that polish excessively and become slippery. Highlights Development, characterization and application of hybrid materials are reviewed.
Hybrid materials are composed of two or more components in one matrix. Hybrid materials pose unique properties compared to original components. The properties of hybrid materials change with the component and composition. Hybrid materials perform better compared to conventional coagulant and Cited by: ion exchange , membrane separation methods  and electro-remediation methods are used more commonly to treat industrial wastewater.
Among these methods precipitation is most economical and hence widely used, but many industries still use chemical procedures for treatment of effluents due to economic factors [11, 12].Cited by: Characterization of energetic residues at military firing ranges: Scholfield Barracks and Pohakulao Training Area, HI, Chapter 3 in Pennington, J.C.

Acid mine drainage (AMD) remediation commonly produces byproducts which must be stored or utilized to reduce the risk of further contamination. A mussel shell bioreactor has been implemented at a coal mine in New Zealand, which is an effective remediation option, although an accumulated sludge layer decreased efficiency which was then removed and requires storage.

Knowledge of the waste that enters treatment systems is a basic prerequisite for the design and development of future technology. There is information on conventional sanitary sewage (Henze et al., ; Tchobanoglous et al., ) but this material has a different composition to fresh feces and urine which has not undergone any degradation Cited by: Chitosan or modified chitin is readily soluble in dilute acidic medium below its pKa (pH = ) while chitin is insoluble in organic and regular solvents.

Understanding the solubility of polysaccharides is extremely important for their food applications as most functions of polysaccharides including stability, emulsifying property, drug delivery, membrane forming properties, etc., are all achieved in aqueous solution.

Qualitative and semiquantitative methods, also known as screening methods, are usually used to assay a large number of samples for the presence of one or more contaminants belonging to the same family (e.g., antibiotic residues; see Sect. ).These methods are fast, of low cost, simple, and robust; they are often less sensitive Cited by: 2.
Low aqueous solubility is the major problem encountered with formulation development of new chemical entities as well as for the generic development. More than 40% NCEs (new chemical entities) developed in pharmaceutical industry are practically insoluble in water.
Solubility is a major challenge for formulation by: Combining proteomic and transcriptomic methods, we identified a panel of novel cysteine-rich peptides, roseltides (rT1-rT8), which range from 27 to 39 residues with six conserved cysteine by: 6. The activation of this solid-state signaling and alterations in ECM may contribute to fibroid development (4, 35, 36).

Both the hydrochlorination residue and the solids which remain after leaching the hydrochlorination residue with nitric acid were chlorinated with similar results. By this technique, loss of 1 to 6% of the uranium to the nitric acid insoluble residue, which occurs in simple hydrochlorination and dissolution of STR fuel, is avoided.antimony concentration, the MOV was pulverized and leached in a pre-treatment step.
