Experimental study on the use of granulometric speciation for the radiometric dating of recent sediments
(Elsevier, 2019)
Theoretical and experimental studies have shown that activity concentrations of fallout radionuclides (such as 137Cs and excess 210Pb) decrease with particles size in aqueous suspensions. This paper is aimed at reviewing ...

Formation of antireflection Zn/ZnO core–shell nano-pyramidal arrays by O2 + ion bombardment of Zn surfaces
(Royal Society of Chemistry, 2017-08-25)
ZnO is probably one of the most studied oxides since ZnO nanostructures are a very rich family of nanomaterials with a broad variety of technological applications. Although several chemical techniques offer the possibility ...

Factors related to 41K interference on 41Ca AMS measurements
(ScienceDirect, 2019-01)
Dealing with the 41K interference during 41Ca measurement with low energy AMS systems is challenging. The detection of 39K to correct the measured 41Ca/40Ca ratios is a powerful tool that improves precision and accuracy. ...

Conformal Growth of Organic Luminescent Planar Defects within Artificial Opals
(American Chemical Society, 2010-01)
Herein, we present the result of combining, for the first time, the techniques of colloidal self-assembly and plasma-enhanced chemical vapor deposition to create a novel, high-quality, purely organic active photonic crystal ...

Pterobreathers in a model for a layered crystal with realistic potentials: Exact moving breathers in a moving frame
(American Physical Society, 2019-08-12)
In this article we perform a thorough analysis of breathers in a one-dimensional model for a layered silicate for which there exists fossil and experimental evidence of moving excitations along the close-packed lines of ...

Could bulk density profiles provide information about recent sedimentation rates?
(Springer, 2011)
Independent validation has to be an integral part of the 210Pb-based radiometric dating of recent sediments. The combined use of artificial fallout radionuclides leads to serious problems because only the identification ...

Multicolored Emission and Lasing in DCM-Adamantane Plasma Nanocomposite Optical Films
(American Chemical Society, 2017-03)
We present a low-temperature versatile protocol for the fabrication of plasma nanocomposite thin films to act as tunable emitters and optical gain media. The films are obtained by the remote plasma-assisted deposition of ...

The marine kd and water/sediment interaction problem
(Elsevier, 2018)
The behavior of marine distribution coefficients is analyzed with the help of numerical experiments and ana-lytical solutions of equations describing kinetic models for uptake/release of radionuclides. The difficulties ...

On the effect of thin film growth mechanisms on the specular reflectance of aluminum thin films deposited via filtered cathodic vacuum arc
(MDPI, 2018)
The optimisation of the specular reflectance of solar collectors is a key parameter to increase the global yield of concentrated solar power (CSP) plants. In this work, the influence of filtered cathodic vacuum arc deposition ...

Numerical analysis for 137CS on seabed sediment including atmospheric deposition near the Fukushima coastal area
(2013)
Radionuclides were released into the atmosphere and ocean from the accident at the Fukushima Daiichi Nuclear Power Plant (NPP) in March 2011. Numerical simulations were performed to evaluate the distribution of 137Cs in ...
