Single-ion induced surface modifications on hydrogen-covered Si(001) surfaces—significant difference between slow highly charged and swift heavy ions

New Journal of Physics, 2021
Hydrogen-covered Si(001) surfaces were exposed to swift heavy ions (SHI) and slow highly charged ions (HCI). Using scanning tunneling microscopy as analysis tool, the ion-induced modifications on the surface were resolved on the atomic scale.

Excitation and Relaxation of Swift Heavy Ion Irradiated Dielectrics

e-Journal of Surface Science and Nanotechnology, 2010
The structural modifications of insulators after swift heavy ion irradiation are studied by applying a combination of the Monte-Carlo method (MC), used to describe the excitation and relaxation induced by the penetrating ion in the electronic subsystem, with the two temperature model (TTM) describing the temporal evolution of the lattice temperature ...

Synergistic Advanced Oxidation and Physicochemical Treatment Strategies for Antibiotic Removal and Resistance Mitigation in Water

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...

Fueling Tomorrow: Scenario Planning for the Future of Gas Stations

Business Strategy and the Environment, EarlyView.
ABSTRACT Transport electrification is reshaping the service infrastructures that mediate everyday mobility, yet most electrification scenario studies remain macrolevel and offer limited insight into how incumbent forecourt (gas‐station) networks can adapt under deep uncertainty.

Detector response to swift heavy ions

Radiation Effects and Defects in Solids, 1989
Track theory is a description of the structure of particle tracks which characterizes the response of many different sorts of "detectors" to energetic heavy ions. It is a parametric rather than a mechanistic description. The medium is a black box containing targets whose response to gamma rays is described by the cumulative Poisson distribution.
