Pt particles sintering on Pt/SiO2 during water denitrification

Catalysis Communications, 2021
Platinum particle growth in aqueous phase has been investigated at 20 °C in the course of nitrite (NO2−) reduction by H2 reaction. A shift from a monomodal to a bimodal particle size distribution on used catalysts is accompanied with the disappearance of

Unraveling the Non‐Homogeneous Dispersion Processes in Ocean and Coastal Circulations Using a Clustering Approach

Geophysical Research Letters
Dispersion processes in environmental flows have been traditionally studied under the strong assumption of homogeneous, isotropic and stationary turbulence.

Analysis of Dispersion with Incomplete Observations on One of the Characters

Journal of the Royal Statistical Society Series B: Statistical Methodology, 1956
Summary In analysis of dispersion (multivariate generalization of the analysis of variance) Wilks' A criterion for testing hypotheses on all the multiple characters simultaneously cannot be applied if some observations on one or more of the characters are missing.

An Electronic Structural Analysis of O₂-Binding Dicopper Complex: Insights from Spin Magnetism and Molecular Orbitals

Chemistry
We investigated the geometry and electronic structure of the oxygen-bridged dicopper complex [CuII2(NH3)4O2]2+ and discussed how different DFT methods and basis sets, including dispersion corrections and dielectric media, affect the predicted structure ...

Where do cultural workers live and act? The spreading and dispersal of cultural spaces in Slovenia [PDF]

Družboslovne Razprave, 2018
The article aims to examine the dynamics of the spatial distribution of cultural workers at various spatial scales in Slovenia. The dispersion of cultural workers is studied using a quantitative analysis of their place of residence and work.

The role of losses in determining hyperbolic material figures of merit

Scientific Reports
Uniaxial materials have achieved new prominence in photonics because they can have hyperbolic spectral regions with metallic (ε0) permittivities along different crystal axes.

Engineering method to build the composite structure ply database

Results in Physics, 2016
In this paper, a new method to build a composite ply database with engineering design constraints is proposed. This method has two levels: the core stacking sequence design and the whole stacking sequence design.

Investigation of spectroscopic and thermo-mechanical behaviors of different phenanthroimidazole-azo dyes in solvent and polymer medium

Materials Research Express, 2020
The aim of this study is the investigation of the interaction between dyes and polymers which have different polarities. Dye doped polymer films have larger application areas because of the fact that dye is more stable when doped in polymer compared to ...
