KEMS448 Physical Chemistry Advanced Laboratory Work
... In this laboratory work, the surface tension of an anionic tenside molecule, sodium dodecyl sulphate (NDS), is measured as a function of concentration. From the results, the critical micelle concentration is determined and the behaviour of surface excess as a function of the concentration is examine ...

Nitric Oxide Production from Synthesized Ruthenium (III) Porphyrins
... Triphenylphosphine oxide (OPPh3) was qualitatively observed by gas chromatographic methods. The mechanism of nitrite coordination and oxidation of the PPh3 to OPPh3 was shown to be redox dependant. The activated complex undergoes reduction from RuIII to RuII corellating with the rate of nitrosyl for ...

... act as discrete magnetic domains. SMMs have attracted attention recently because, after being magnetized at low temperatures (< 5 K), the magnetization can be retained as the strength of the external magnetic field is lowered. This property may permit SMMs to be utilized as components for nano-scale ...

Chirality in amino acid over layers at metal crystal surfaces
... The building blocks of living organisms - amino acids and sugars - exhibit chirality. Moreover, naturally occurring amino acids all occur in just one of the two enantiomeric forms: amino acids occur in the L form (except glycine, which is achiral), sugars in the D form. Getting the chirality right c ...
