Photoluminescence properties of magnesium, chloroaluminum, bromoaluminum, and metal-free phthalocyanine solid films
Article Abstract:
Photoluminescence properties of vacuum-deposited thin films of magnesium, chloroaluminum, bromoaluminum and metal-free phthalocyanines in as-deposited phases and red-shifted phases, which are prepared by vapor treatment of organic solvents is measured. The fluorescence quantum yields of the films at room temperature was determined to be 10(super -5) - 10(super -4), which were much smaller than the values of the corresponding monomers, thus indicating the dominance of the nonradiative relaxation in the solid films.

Conductivity measurements of dilute aqueous LiOH, NaOH, and KOH solutions to high temperatures and pressure using a flow-through cell
Article Abstract:
The (lambda0) values presented in this study has shown that the new results are in agreement with the values measured using the static cell for LiOH, NaOH and KOH at (Rho) greater than or equal to 0.5g.cm(super -3) but are slightly higher and less scattered below 0.5 g.cm(super -3) especially in the cases of NaOH and KOH. The flow through cell is designed to measure molar conductances of dilute aqueous electrolytes with a high degree of accuracy at high temperatures and pressures.

Outer-shell and inner-shell coordination of phosphate group to hydrated metal ions (Mg(super 2+), Cu(super 2+), Zn(super 2+), Cd(super 2+)) in the presence and absence of nucleobase. The role of nonelectrostatic effects
Article Abstract:
Inner-shell binding of selected hydrated metal ions (Mg(super 2+), Cu(super 2+), Zn(super 2+), Cd(super 2+)) to the guanine N7 position accompanied with the outer-and inner-shell binding to an anionic phosphate group is investigated using quantum chemical approaches. The Zn(super 2+) and Cd(Super 2) cations show a clear preference to bind to N7 of guanine compared to Mg(super 2+) whereas Cu(super 2+) shows even stronger relative preference for N7 metal binding.
