Direct observation of damage clustering in irradiated DNA with atomic force microscopy
DNA carries the genetic information inside the cells and represents a sensitive target of ionizing radiation. Ionizing radiations induce free radicals in DNA constituents and thereby produce various types of DNA lesions such as base damage, DNA single-strand breaks (SSBs), DNA doublestrand breaks (DSBs), and DNA-protein crosslinks Ionizing radiation produces clustered DNA damage that contains two or more lesions in 10–20 bp.

How water wets and self-hydrophilizes nanopatterns of physisorbed hydrocarbons
Weakly bound, physisorbed hydrocarbons could in principle provide a similar waterrepellency as obtained by chemisorption of strongly bound hydrophobic molecules at surfaces.

Emerging illuminated and operando techniques for solar fuel research
Integrated photoelectrochemical devices rely on the synergy between components to efficiently generate sustainable fuels from sunlight. The micro- and/or nanoscale characteristics of the components and their interfaces often control critical processes of the device, such as charge-carrier generation, electron and ion transport, surface potentials, and electrocatalysis.

Reorganization energy upon charging a single molecule on an insulator measured by atomic force microscopy
Intermolecular single-electron transfer on electrically insulating films is a key process in molecular electronics and an important example of a redox reaction. Electron-transfer rates in molecular systems depend on a few fundamental parameters, such as interadsorbate distance, temperature, and, in particular, the Marcus reorganization energy.
