Mixed ligand com plexes of bis(phenyldithiocarbazato)nickel(II) with triphenylphosphane and a number of ditertiary phosphanes have been synthesised. The com plexes were characterised on the basis of molar conductance, magnetic moment values, electronic and IR spectra. Out of the five prepared com plexes the mixed ligand com plexes with triphenylphosphane and bis(diphenylphosphino)m ethane are p...

The retrieval of data from the Cassini-Huygens mission has revealed much about Titan's atmospheric-surface system and has precipitated more questions. One of these questions involves the lack of large reservoirs of ethane that were predicted by a variety of studies prior to the arrival of the Cassini-Huygens spacecraft. Using an updated and comprehensive photochemical model, we examine the natu...

Light dependent ethane formation and chlorophyll bleaching in isolated chloroplast lamellae are enhanced by either methylviologen or a-linolenic acid. Both ethane formation and chloro­ phyll bleaching are also enhanced in chloroplast particles deficient in photosynthetic electron transport, e. g. after aging, heat treatm ent or digitonin fragmentation. Ethane formation by sub­ chloroplast parti...

Three new types of Gemini amphiphiles (N ,N ?-bis-(4-decyloxybenzylidene)-ethane-1,2-diamine, N ,N ?-bis-(4decyloxy-2-hydroxybenzylidene)-ethane-1,2-diamine, and (N ,N ?-bis-(4-decyloxy-2-hydroxybenzylidene)-ethane-1,2diamine)copper(II) were synthesized. Their aggregation behaviors were studied by TEM observation and monolayer experiments. It was found that the vesicle formation and transformat...

The hydrogenolysis of ethane has been investigated on clean and Ni-covered Pt( 1 1 1) at reactant partial pressures between 0.5 and 4 Torr of ethane and between 80 and 270 Torr of hydrogen and for surface temperatures from 550 to 640 K. On clean Pt( 1 1 1) the hydrogenolysis reaction proceeds with an activation energy of 36.6 kcal/mol and reaction orders in C2H6 and H2 pressures of 1 and -1.8, ...

the srk two-parameter cubic equation of state has been used for the calculation of the equilibrium constant using the liquid and vapor fugacity coefficients for three binary mixtures. dew and bubble points have been determined using the equilibrium constants and the phase envelope has been plotted showing dearly that retrograde condenstaion occurs. the following percent deviations have been obt...

After alfalfa (Medicago sativa) seedlings were exposed to approximately 0.7 microliter per liter SO(2) for 8 hours, elevated ethylene and ethane production was observed. Ethylene production peaked about 6 hours and returned to control levels by about 24 hours following the fumigation, while ethane production peaked about 36 hours and was still above control levels 48 hours after the fumigation....

Using orthogonally polarized 800 nm and 400 nm laser pulses, we have generated high harmonics in ethane (C(2)H(6)). We observe that the intensity of each harmonic order modulates with the attosecond delay between the two laser fields. The modulation period of the low even harmonics is twice that of the period of modulation of the other harmonics. By comparing with theoretical calculation, we sh...
