Slow-release of methanogenic inhibitors derived from encapsulated calcium carbide using paraffin wax and/or rosin: matrix optimization and diffusion characteristics.
Waste Manag Res 29(11) , 1197-204, (2011) Acetylene has been found to significantly inhibit biological activity of methanogens and thus might be applicable for reducing the generation and emission of methane from municipal solid waste landfills. However, acetylene is gaseous and so it is considered p... |

[Severe ocular burns by calcium carbide in a speleologist: a case report].
J. Fr. Ophtalmol. 25(3) , 308-11, (2002) A case of severe ocular burns in an amateur speleologist is reported. The explosion of his acetylene lamp caused the projection of calcium carbide particles, which induced burning of the cornea and conjunctiva in both eyes. He slowly recovered in several mont... |

Pressure-induced superconductivity in CaC2.
Proc. Natl. Acad. Sci. U. S. A. 110(23) , 9289-94, (2013) Carbon can exist as isolated dumbbell, 1D chain, 2D plane, and 3D network in carbon solids or carbon-based compounds, which attributes to its rich chemical binding way, including sp-, sp(2)-, and sp(3)-hybridized bonds. sp(2)-hybridizing carbon always capture... |

Determination of total body water by a simple and rapid mass spectrometric method.
J. Mass Spectrom. 31(1) , 108-11, (1996) A rapid and inexpensive method was developed to determine deuterium enrichment in body fluids. This is achieved by converting water into acetylene. To vacutainer tubes a small amount of calcium carbide is added. The tubes are evacuated and 25 microliters of s... |

[Optimization on slow-release inhibition of biomethane and the kinetics model of diffusion].
Huan Jing Ke Xue 31(7) , 1689-94, (2010) The diffusion mechanism of acetylene,which can inhibit the activity of methanogens, was studied. Paraffin wax and rosin were used as matrix of slow-release and calcium carbide was used as inhibition material. Based on the T. Higuchi equation and the character... |

[Calcium carbide of different crystal formation synthesized by calcium carbide residue].
Huan Jing Ke Xue 27(4) , 775-8, (2006) To recycle calcium carbide residue effectively, calcium carbide of different crystal form, including global aragonite, calcite and acicular calcium carbide was synthesized. Both the influence of pretreatment in the purity of calcium carbide, and the influence... |

[Effect of substrate-dependent microbialy produced ethylene on plant growth].
Mikrobiologiia 75(2) , 277-83, (2006) Various compounds have been identified as precursors/substrates for the synthesis of ethylene (C2H4) in soil. This study was designed to compare the efficiency of four substrates, namely L-methionine (L-MET), 2-keto-4-methylthiobutyric acid (KMBA), 1-aminocyc... |
