Kelvin Probe Force Microscopy in Bionanotechnology: Current Advances and Future Perspectives

Advanced Materials, EarlyView.
Kelvin probe force microscopy (KPFM) enables the nanoscale mapping of electrostatic surface potentials. While widely applied in materials science, its use in biological systems remains emerging. This review presents recent advances in KPFM applied to biological samples and provides a critical perspective on current limitations and future directions for

Cyclic Conjugation Energy Effects in Polycyclic π-Electron Systems

Monatshefte für Chemie - Chemical Monthly, 2005
The fact that cyclic arrangements of double bonds have a dramatic effect on the behavior of conjugated organic molecules is known since the 19th century. The fact that in monocyclic conjugated systems the size of the cycle and the number of π-electrons involved is decisive for their stability (“aromaticity”) or lack of stability (“antiaromaticity”) is ...

CYCLIC CONJUGATION IN PYRACYLENE [PDF]

Polycyclic Aromatic Compounds, 2008
Cyclic conjugation of the π-electrons in pyracylene is studied by means of the energyeffects (ef) of its various cycles. The calculated ef-values imply that cyclic conjugation significantly destabilizes the pyracylene molecule.

Energy Component Analysis of the Pseudo-Jahn−Teller Effect in the Ground and Electronically Excited States of the Cyclic Conjugated Hydrocarbons:  Cyclobutadiene, Benzene, and Cyclooctatetraene

The Journal of Physical Chemistry A, 1997
To elucidate the nature of the pseudo-Jahn−Teller (JT) effect, an energy component analysis has been carried out for the ground and electronically excited states of the titled cyclic polyenes by using the MCSCF method with 6-31G(d) basis set. Examination of the energy components comprised in the total energy reveals that in the ground state of planar ...
