We report on the size dependence of the melting temperature of silica-encapsulated gold nanoparticles. The melting point was determined using differential thermal analysis (DTA) coupled to thermal gravimetric analysis (TGA) techniques. The small gold particles, with sizes ranging from 1.5 to 20 nm, were synthesized using radiolytic and chemical reduction(More)
We study in a quantitative way CP-violating effects in neutrino oscillation experiments in the light of current and future data. Different scenarios with three and four neutrinos are worked out in detail including matter effects in long baseline experiments and it is shown that in some cases CP-violating effects could affect the analysis of a possible(More)
As spherical hosts for neutral arenes, the macrobicyclic compounds 2 and 3 were synthesized. 1 -Acetyl-4,4-bis[4-succinimidyloxycarbonylmethoxy-3,5-dimethylphenyl]piperidine (8) and l-ethyl-4,4-bis[4-(2-aminoethoxy)-3,5-dimethylphenyllpiperidine (10) were cyclized to the tetraoxadiaza[ Iparacyclophane 4. Cyclization component 8 was obtained by(More)
