The modern version of the KKR (Korringa–Kohn–Rostoker) method represents the electronicstructure of a system directly and efficiently in terms of its single-particle Green's function. Direct access to the Green function results in several appealing features. In particular the description of the electronic correlations, disorder and electronic spectroscopies for the nanosystems and surfaces has been developed in the recent years. In the first part of my talk I will review basic ideas of the multiple scattering KKR formalism. Second part will be devoted to the Angle-resolved photoemission...

Carbon electrodes are routinely used in electrochemical detectors and sensors to quantify electroactive analytes in solution. By electroactive, one is referring to molecules that are easily oxidized or reduced at an electrode surface. Generally speaking, electrochemical measurements often involve application of a potential to an electrode and measuring the current that flows in response to the potential perturbation, which is reflective of the local analyte concentration. Carbon is one of the most abundant elements found on the planet and, from a materials perspective, is unique because of...

Abstrakt: Hexa-peri-hexabenzocoronene (HBC) core tethered with three diacetylene (DA)-containing side-chains was designed and their self-assembling behavior in solvent and on substrate was investigated. The polymerizable HBC derivatives are noted as HBC-1,3,5-Ph-DA-Cn, where 1,3,5 refers to the position of DA chain and n is the spacer length of alkyl chain. It is confirmed that the nanostructure of HBC-1,3,5-Ph-DA-Cn can be polymerized in (i) solution and (ii) film by UV-irradiation or thermal treatment. HBC-1,3,5-Ph-DA-C12 exhibits a stable hexagonal columnar phase at 47°C which was used to...
