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 landfil...

[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 co...

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...
