BSA-IrO2 : Catalase-like Nanoparticles with High Photothermal Conversion Efficiency and a High X-ray Absorption Coefficient for Anti-inflammation and Antitumor Theranostics.

Angewandte Chemie, 2018
Intrinsically integrating precise diagnosis, effective therapy, and self-anti-inflammatory action into a single nanoparticle is attractive for tumor treatment and future clinical application, but still remains a great challenge.

Considerations on sound absorption coefficient of sustainable concrete with different waste replacements

Journal of Cleaner Production, 2018
In the context of an urban environment assaulted by noise from different sources, the possibility of using composite materials made of concrete and various materials considered as waste was investigated, for the purpose of using them in acoustic barriers.

Optimization of the spectral absorption coefficient of a plasmonic nanofluid for a direct absorption solar collector

Solar Energy, 2018
Direct absorption solar collector (DASC) has been a prevalent research topic in utilizing the solar energy. Usually, a nanofluid is employed in a DASC so that the solar radiation can be absorbed directly and the heat loss is reduced substantially ...

On the Kubelka–Munk absorption coefficient

Dyes and pigments, 2016
The Kubelka–Munk equation is solved approximately for paint films with finite thickness, an inequality is induced in the solution process, and a minimal Kubelka–Munk absorption coefficient is obtained.

Absorption Coefficients for Exciton Absorption Lines

Physical Review, 1957
The absorption coefficient for excitons is calculated in the effective-mass approximation. The coefficient is shown to be decreased over what one would expect for a collection of free atoms by the factor ${\ensuremath{\epsilon}}^{\ensuremath{-}1}{(\frac{{a}_{0}}{{a}_{B}})}^{3}$, where $\ensuremath{\epsilon}$ is the dielectric constant and $\frac{{a}_{0}

Gamma ray absorption coefficients

Proceedings of the Physical Society, 1964
The experimental and theoretical values of scattering cross sections of gamma radiation, reported by Lakshminarayana and Jnanananda in 1961, have been extended to cover a wider range of atomic numbers and photon energies.
