We provide a study of ligand place-exchange reaction on Au nanoparticles. Nanoparticles of the dimensions of 7–9 nm were fabricated by high-temperature anhydrous route in the presence of primary aliphatic amine. The advantage of weak coordination to gold, through the nonbonding electrons of the amino group, was to use in an exchange of an initial protective ligand. Therefore, among other stabil...

Abstract Various systematic modifications of vectorial Boolean functions have been used for finding new previously unknown classes S-boxes with good or even optimal differential uniformity and nonlinearity. In this paper, a general modification method is given that preserves the bijectivity property function in case inverse admits linear structure. A known construction such based on bijective G...

We present the results of the interferometric observations of the circumstellar disk surrounding MWC 297 in the continuum at 230 GHz (1.3 mm) and in the (J=2-1) rotational transitions of 12CO,13CO and C18O using the Submillimeter Array. At a distance of 250 pc, MWC 297 is one of the closest, young massive stars (M⋆ ∼10 M⊙) to us. Compact continuum emission is detected towards MWC 297 from which...

Flavour changing neutral decays of the top quark are know to be extremely suppressed in the SM. This is especially so for the top quark decay into the SM Higgs boson, whose rate is less than 10. However, it turns out that the decay modes t → c h, with h ≡ h, H, A any of the MSSM neutral Higgs bosons, can be much more gifted. In particular, the rate into the lightest CP-even Higgs boson h – whic...

We have obtained, for the first time, a high resolution near-infrared spectrum in the region of Paβ of a chromospheri-cally active M dwarf (AU Mic). We demonstrate that both Paβ and Hα can be fit with a model of large chromospheric pressure , but that the two lines indicate clearly different values of the exact pressure. There are several important types of missing physics that need to be inclu...
