Determination and assessment of a complete and self-consistent electron-neutral collision cross-section set for the C4F7N molecule

Journal of Physics D: Applied Physics, 2023
The perfluoronitrile C4F7N is considered a promising SF6-alternative in high-voltage gas-insulated apparatus, thanks to its high dielectric strength and low global warming potential.

Neutrino Cross Sections and Scattering Physics [PDF]

AIP Conference Proceedings, 2006
Large flux uncertainties and small cross sections have made neutrino scattering physics a challenge. However, a worthwhile challenge, as these tiny particle interactions can teach us a lot about neutrinos themselves, the weak interaction, and nucleon structure. As well, knowledge of these cross sections is crucial input to the growing field of neutrino

Physical activity and the menopause experience: A cross-sectional study

Maturitas, 1994
A randomly selected community cohort of 2000 Australian born women aged 45 to 55 were interviewed on the telephone and information obtained on their health and well-being. These women were divided into pre-, peri-, natural and surgical menopausal groups on their menstrual history.

Low-frequency anechoic metasurface based on coiled channel of gradient cross-section

Applied Physics Letters, 2019
This letter proposed advantageous in-uniform gradient cross-section (GCS) channels which weaken the dependence of the coiled-up anechoic metasurface on the total channel length. The privilege of GCS channels was revealed by studying Fabry-Perot absorbers

On the determination of absorption cross section of colloidal lead halide perovskite quantum dots.

Journal of Chemical Physics, 2019
The absorption cross section of lead halide perovskite nanocrystals is important for understanding their photophysical properties, especially those depending on the density of photoexcited charge carriers.
