An organic iodine remover is a remover for removing organic iodine and is a substance composed of a cation and an anion, and the cation (for example, a phosphonium cation, an ammonium cation, or a sulfonium cation) has a molecular structure in which an electron donating group (for example, a phosphino group, an amino group, a sulfanyl group, a hydroxy group, or an alkoxy group) is bonded to a phosphorus atom, a nitrogen atom or a sulfur atom. An organic iodine removing apparatus includes: a vessel into which the organic iodine remover for removing the organic iodine is charged; and introduction pipes through which a fluid containing organic iodine is introduced into the organic iodine remover.

Methods of scintillation, scintillation devices, and metal halide hybrids that may be used as X-ray scintillators. The metal halide hybrids may include organic metal halide hybrids, inorganic metal halide hybrids, or organic-inorganic metal halide hybrids. The metal halide hybrids may have a 0D structure. The metal halide hybrids may be in the form of one or more discrete crystals.

##STR00001##

wherein Z is N or P, and R.sup.1, R.sup.2, R.sup.3, and R.sup.4 are independently selected from hydrogen atom and hydrocarbon groups having one to four carbon atoms with optional interconnection to form a cyclic group that includes Z, and wherein R.sup.1, R.sup.2, R.sup.3, and R.sup.4 are all hydrocarbon groups when Z is P, and X.sup.− is a phosphorus-containing or carboxylate anion, particularly an organophosphate, organophosphonate, or organophosphinate anion, or a thio-substituted analog thereof containing hydrocarbon groups with at least three carbon atoms. Also described are lubricant compositions comprising the above ionic liquid and a base lubricant, wherein the ionic liquid is dissolved in the base lubricant. Further described are methods for applying the ionic liquid or lubricant composition onto a mechanical device for which lubrication is beneficial, with resulting improvement in friction reduction, wear rate, and/or corrosion inhibition.
