“…As is well known, the construction of coordination compounds is mainly dependent on the combination of several factors, such as the organic ligands, solvents, metal atoms and counter-ions [1][2][3]5,17,18,27]. Polycarboxylate ligands, as good candidates for the construction of coordination compounds, have aroused a good deal of interest from chemists.…”

“…Coordination compounds which exhibit a high surface area and large pore volume are of great current interest for their specific structural features [1][2][3][4][5][6][7] and potential applications, such as gas storage [8][9][10], separation [11,12], carbon dioxide capture [13] and catalysis [14]. Just recently, an increasing number of reports on coordination compounds as photocatalysts have appeared to indicate that they provide a unique opportunity for integrating different molecular functional blocks to obtain good performance of organic pollutant degradation [15][16][17][18][19][20][21], CO 2 reduction [22][23][24] and Cr(VI) reduction [25,26].…”

Theoretical predictions for the α-decay chain of the nucleus 296 118 are performed. The synthesis of this nucleus is being attempted in experiments running in Dubna. The α-decay energies Q α , and the α-decay and spontaneous-fission half-lives, T α and T sf , are studied. The analysis of the α decay is based on a phenomenological model using only three parameters. The calculations are performed in nine variants using masses obtained within nine nuclear-mass models describing masses of the heaviest nuclei. The experimental Q α energies, known from earlier experiments for the potential daughter, 292 Lv, and grand-daughter, 288 Fl, nuclei are reproduced with an average of the absolute values of the discrepancies: from 0.13 to 1.52 MeV within the considered variants. Measured half-lives T α are reconstructed within average ratios: from 1.7 to 1054. Within all variants considered, the half-life T α of the nucleus 296 118 is obtained larger than needed (around 1 μs) for its observation.

“…They have been produced in cold fusion or hot fusion ( 48 Ca projectile) reactions [39][40][41][42]. In a systematic study of α-decay energies and half-lives of superheavy nuclei it was shown [44] that our semFIS (semiempirical formula based on fission theory) and UNIV (universal curve) are the best among 18 calculations methods of α decay half-lives. For some isotopes of even heavier SHs, with Z > 121, there is a good chance for cluster decay modes to compete [29,43].…”

A new semi-empirical formula for calculations of α decay halflives is presented. It was derived from Royer relationship by introducing new parameters which are fixed by fit to a set of experimental data. We are using three sets: set A with 130 e-e (even-even), 119 e-o (even-odd), 109o-e, and 96 o-o, set B with 188 e-e, 147 e-o, 131 o-e, and 114 o-o, and set C with 136 e-e, 84 e-o, 76 o-e, and 48 o-o alpha emitters. A comparison of results obtained with the new formula and the following well known relationships: semFIS (semiempirical based on fission theory); ASAF (analytical superAsymmetric fission) model, and UNIV (universal formula) is made in terms of rms standard deviation. We also introduced a weighted mean value of this quantity, allowing to compare the global properties of a given model. For the set B the order of the four models is the following: semFIS; UNIV; newF, and ASAF. Nevertheless for even-even alpha emitters UNIV gives the 2nd best result after semFIS, and for odd-even parents the 2nd is newF. Despite its simplicity in comparison with semFIS the new formula, presented in this article, behaves quite well, competing with the others well known relationships
