Ultrafast excitation relaxation dynamics of lutein in solution and in the light-harvesting complexes II isolated from Arabidopsis thaliana

Article Abstract:

Ultrafast excitation relaxation dynamics and energy-transfer processes in the light-harvesting complex II(LHC II) of Arabidopsis thaliana are examined at physiological temperature using fentosecond time-resolved fluorescence spectroscopy. On the basis of the results, relaxation processes and energy-transfer kinetics in LHC II of Arabidopsis thaliana are discussed.

Electron transfer through organic monolayers directly bonded to silicon probed by current sensing atomic force microscopy: effect of chain length and applied force

Article Abstract:

Electron transfer through organic monolayers directly bonded to a silicon surface has been investigated by using a current sensing atomic force microscope (CSAFM). The research system employed a platinum-coated CSAFM tip in point contact at a confined nanometer size with a set of alkyl monolayers of various chain lengths.

Investigation of the self-organization of lutein and lutein diacetate by electronic absorption, circular dichroism spectroscopy, and atomic force microscopy

Article Abstract:

Spontaneously forming H- and J-type chiral self-assemblies of lutein and lutein diacetate were studied by means of ultraviolet-visible and circular dichroism spectroscopy (CD). Existence of chiral superstructures in both solution and solid phases with opposite and handedness was demonstrated.
