Surface Micro‐Discharge Plasma for Multiple Teeth Bleaching: Efficacy, Mechanism and Safety

High Voltage, EarlyView.
ABSTRACT Hydrogen peroxide (H2O2) is the commonly‐used bleaching chemical in clinical practice, but its excessive concentrations can cause tooth damage. Atmospheric pressure cold plasma is considered a promising new technique for tooth bleaching. Surface micro‐discharge (SMD) devices can generate large‐scale plasma, which holds potential for treating ...

Measurement and simulation of indoor radon concentration distribution in students’ residential hostels around Ladoke Akintola University of Technology, Ogbomoso, Nigeria

African Scientific Reports
Radon is a harmful gas and class I carcinogen posing global challenge to human health. Being an inert gas, it is impossible to perceive its presence by any of the sense organs, thus the application of Computational Fluid Dynamics (CFD) simulation in ...

Determination of the one‐electron reduced Wigner function for a molecular crystal

Acta Crystallographica Section A, EarlyView.
The first reconstruction of an experimental one‐particle reduced Wigner function for electrons in molecular crystals is reported. It relies on an ensemble N‐representable model jointly refined from the X‐ray diffraction and Compton scattering data.The Wigner function provides a complete phase‐space representation of a quantum state.

The radon gas. An air pollutant

, 2010
In this work different aspects about the problem of the radon in dwellings are approached. This gas of natural origin is virtually present in all the soils in the earth’s crust due to the presence of uranium and radium in the composition of them. Depending on architectural factors and of occupancy habits of the house, high concentrations of this gas ...
