    Analysis of serpentine polymorphs in investigations of natural occurrences of asbestos.[Pubmed: 25942071]
    This work investigates potential analytical variability in environmental investigations of natural occurrences of asbestos (NOA) due to intergrown Serpentine minerals.
    Franciscan complex and serpentinite rock samples were obtained from likely NOA sites in coastal Northern California with geographic information system (GIS) maps, then analyzed using polarized light microscopy (PLM), transmission electron microscopy with energy-dispersive X-ray analysis and selected area electron diffraction (TEM/SAED/EDS), and environmental scanning electron microscopy with EDS (ESEM/EDS). Non-asbestos Serpentine fibers were superficially similar to chrysotile but were differentiated quickly using TEM morphology criteria and reference SAED overlays. 94 NOA fibers were classified as asbestiform chrysotile (62%), polygonal Serpentine (34%), lizardite scrolls (2%), and lizardite laths (2%). Chrysotile fibril widths (mean = 42 nm) were significantly different from those of polygonal Serpentine and lizardite laths (167 and 505 nm, respectively), but not lizardite scrolls (37 nm).

    A facile route to preparation of high purity nanoporous silica from acid-leached residue of serpentine.[Pubmed: 25924349]
    As the current cost of mineral carbonation is too high for an economically viable industrial process, it is desirable to produce value-added products from CO2 mineralization process.
    In this work, a facile and cost-effective process was developed for the production of high purity SiO2 from acid-leached Serpentine residue.

    Methodologies for determining the sources, characteristics, distribution, and abundance of asbestiform and nonasbestiform amphibole and serpentine in ambient air and water.[Pubmed: 25825806]

    Anthropogenic and nonanthropogenic (erosion) processes contribute to the continuing presence of asbestos and nonasbestos elongated mineral particles (EMP) of amphibole and Serpentine in air and water of urban, rural, and remote environments. The anthropogenic processes include disturbance and deterioration of asbestos-containing materials, mining of amphibole- and Serpentine-bearing rock, and disturbance of soils containing amphibole and Serpentine.
    Atmospheric dispersal processes can transport EMP on a global scale.
    Serpentine Description
    Source: The herbs of Rauvolfia yunnanensis
    Solvent: Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
    Storage: Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).

    Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

    Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

    After receiving: The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.
