The at least one constituent can be cyclopropane or cyclobutane.

The application discloses a preparation method of a pyrite particle electrode based on a mechanochemical method, and adopts a normal-temperature wet-type ball milling process to simultaneously perform particle size refining, surface defect construction and nitrogen-doped carbon coating on natural pyrite and defatted soybean powder in an organic solvent, so that the destruction of a crystal form caused by high-temperature treatment is avoided. Then, the obtained composite powder is mixed with acetylene black, and ion cross-linking forming is performed on sodium alginate and calcium chloride in a low-temperature environment, so that a particle electrode with a three-dimensional porous structure is prepared. The method solves the problems of easy agglomeration and loss of the powder and poor conductivity, and the prepared electrode exhibits excellent charge transfer performance and catalytic activity in a 3DERs-PS system, has high degradation efficiency on rhodamine B and good cycle stability, and realizes efficient treatment of organic wastewater.

A method of densifying a plasma-resistant coating layer includes applying a fluorocarbon material including CxHyFz (where x and z are each independently a real number greater than 0, and y is an integer greater than or equal to 0) to a surface of a base material having a surface including YaOb (where a and b are each independently a real number greater than 0) to form a fluorocarbon coated base material, and projecting a pulsed laser beam onto a region of the fluorocarbon coated base material to form a coating layer over the base material, in which coating layer yttrium (Y) and fluorine (F) are bonded together, wherein the coating layer is formed by a laser sintering process occurring by projecting the pulsed laser beam.
