The critical temperature and the critical pressure of pure hydrogen peroxide have been determined by extrapolation. The results are compared with the values predicted by various methods |

Izmodenov // Glass Physics and Chemistry. - 2008. - Vol. 34, № 2. - С. 173-181 Рубрики: ФИЗИКА Кл.слова (ненормированные): HYDROGEN Аннотация: The stabilization of the structure of Si73 clusters that are surrounded by 60 hydrogen atoms and subjected to seventeenfold stepwise heating from 35 to 1560 K (in steps of ?90 K) is investigated using the molecular dynamics method. The analysis is performed for clusters of three types, i.e., a particle assembled from an icosahedron and a fullerene, a nanocrystal, and a particle with a random atomic packing. In all cases, an increase in the temperature in the course of heating is accompanied by evaporation of a Si atom from the clusters and an increase in the size of silicon particles. The temperature of detachment of Si atoms from clusters is lowest for the cluster with a random atomic packing and highest for the nanocrystal. The nanoassembled particle has the most stable number (close to four) of Si-Si bonds per atom over the entire temperature range 35 ? T ? 1560 K. For each type of Si73 clusters, the mean length of the Si-Si bond decreases with an increase in the temperature. According to the radial distribution functions, the Si73 clusters have different structures even at the temperature T = 1560 K. The distributions of bond angles reflect the presence of fourfold symmetry elements in the nanoassembled cluster and the nanocrystal. The relative depth of “penetration” of hydrogen atoms into the cluster is largest for the nanocrystal and smallest for the nanoassembled nanoparticle. The largest number of hydrogen atoms is “adsorbed” on the particle with a random atomic packing. \\\\Expert2\\NBO\\Glass Physics and Chemistry\\2008, v. 34, N 2, p.173.pdf |

Novruzov // Colloid Journal (Translation of Kolloidnyi Zhurnal) Рубрики: ФИЗИКА Кл.слова (ненормированные): AQUEOUS SYSTEM -- DIELECTRIC PERMITTIVITIES -- FLEXIBLE MOLECULES Аннотация: Using the molecular dynamics method, the joint absorption of oxygen and nitrate ions by water clusters is studied in terms of the polarizable model of flexible molecules. Significant fluctuations are observed in the number of hydrogen bonds in the clusters during the addition of MO 3 -ions to water-oxygen aggregates. Dielectric permittivity noticeably changes upon the addition of O 2 molecules to water clusters and nitrate ions to oxygen-containing water clusters. After the absorption of oxygen molecules and nitrate ions, water clusters markedly lose the ability to IR absorption. The Raman spectrum of a medium formed from disperse aqueous system, oxygen, and nitrate ions displays a greater number of bands than the spectrum of a system of pure water clusters |
