Opis:: Two different procedures for the study of the quenching of excited states by lanthanide complex ions on the surface of micelles are considered. In the first, excited Tb(pdc)$\text{}_{3}^{3-}$ (pdc = pyridine 2,6-dicarboxylate) complex ions are held in close proximity to other Ln(pdc)$\text{}_{3}^{3-}$ ions on the surface of cetyl trimethyl ammonium micelles. Efficient energy transfer is observed by the electric dipole-electric dipole mechanism with a mean interaction distance only slightly greater than that which exists in the crystalline complexes. In the second, the excited state of Tb(pdc)$\text{}_{3}^{3-}$ is depopulated by energy transfer to the coexcited lowest excited triplet state of phenanthrene which is thereby excited to the second triplet state.

Opis:: Thermal behavior and microstructure of $Fe_{81 - x}Co_{x}Zr_7Nb_2B_{10}$ (x = 2, 4, 6) alloys were investigated by differential thermal analysis and X-ray diffraction. Both the supercooled liguid region Δ $T_{x}$ and the first crystallization peak temperature $T_{p1}$ are the lowest and the span Δ $T_{p}$ between $T_{p1}$ and $T_{p2}$ is the highest when 4 at.% Fe is substituted by Co. The crystallization activation energy $E_{p1}$ for $Fe_{75}Co_6Zr_7Nb_2B_{10}$ alloy is the minimum for the heating rates ν = 5-20 K/min. $E_{p1}$ for $Fe_{77}Co_4Zr_7Nb_2B_{10}$ alloy is the minimum for the heating rates ν = 20 - 50 K/min. The crystallization processes of $Fe_{81 - x}Co_{x}Zr_7Nb_2B_{10}$ (x = 2, 4, 6) amorphous alloys are similar on the whole, which is as follows: amorphous → amorphous + α-Fe(Co) → α-Fe(Co) + $Fe_3Zr$ + $Fe_2Nb_{0.4}Zr_{0.6}$.

Opis:: A surface-breakdown triggered vacuum switch with parallel disk electrodes and semiconductor surface flashover trigger electrode has many advantages, it is easy to be triggered and machined. The resistance of the trigger gap has been increased in terms of modifying the thickness of the semiconductor layer and improving coating process technology. The trigger gap resistance, trigger voltage and trigger waveforms were experimentally tested. The results show that the triggering characteristics can be improved by increasing the trigger resistance.
