Description: This presentation discusses research on the possible existence of molecules BrKrCCKrBr and FKrCCKrCCKrF. Computational chemistry combines math, chemistry, and computer science to solve chemical problems. Most computer software packages use the Schrödinger equation to approximate various molecular properties (e.g. optimal geometries, vibrational frequencies, charge distributions, dissociation energies, etc.). Before the 1960's, noble gases were considered inert. XePtF6 was synthesized by Neil Bartlett in 1962, opening a new area of exploration. More recently, organic noble gas compounds have been prepared (HXeCCH, HXeCC, HKrCCH, etc.). The author's research question is are there noble gas compounds with multiple carbon chains? This presentation describes the methods for the research, the results, and the conclusions.

Description: This presentation discusses the synthesis and characterization of nickel and nickel hydroxide nanopowders. Nickel, Ni, and nickel hydroxide, Ni(OH)₂, powders with nanosized particles were synthesized using a chemical method. The polymer Poly(vinyl pyrrolidone) or PVP was added to solutions of Ni for purposes of particle protection. X-Ray analysis revealed the size of Ni(OH)₂ particles to be approximately 19 nanometers in diameter and the sizes of Ni particles to be between 7 and 12 nm.

Description: This presentation discusses research on the quantum mechanical prediction of the existence of rare gas-bound species. Rare gases were considered inert until the first synthesis of a rare-gas compound in 1962. Since then, a number of new rare-gas compounds with important uses in industry and medicine have been theoretically predicted and/or experimentally prepared. With recent renewed interest in the discovery of new rare-gas species, the purpose of this research is to predict the existence of new rare-gas compounds. To accomplish this goal, over 80 hypothetical molecules were analyzed using several quantum mechanical methods: density functional theory (B3LYP) and ab initio theory [MP2 and CCSD(T)]. These quantum mechanical methods were used in combination with necessary molecular orbital descriptors, the augmented correlation consistent basis set [aug-cc-pVnZ, where n=D, T, and Q] to assess the structure and potential stability of the hypothetical molecules. The existence of HArN and HKrN and the non-existence of many other rare-gas compounds are predicted by three computational methods [B3LYP, MP2, and CCSD(T)].
