The Influence and Mechanism of Corrosion on AZ31B Magnesium Alloy in 1,2-propanediol Engine Coolant

open access: yesInternational Journal of Electrochemical Science, 2016
Corrosion mechanism of AZ31B magnesium alloys in 1,2-propanediol coolant has been studied using polarization curves, EIS, SEM and SEM-EDS. Magnesium alloy can be formed a stable and tight protective film in foundation liquid, which can easily be ...

Microstructural Characterization and Electrochemical Behaviour of TiC-reinforced Mo-based Composites

open access: yesInternational Journal of Electrochemical Science, 2020
This article reports on using the spark plasma sintering (SPS) process to prepare a TiC/Mo-based alloy. The engineering application performance of the alloy was evaluated using X-ray diffraction (XRD) and transmission electron microscope (TEM ...

Rotational modulation of the linear polarimetric variability of the cool dwarf TVLM 513$-$46546

open access: yes, 2015
Aims: We aimed to monitor the optical linear polarimetric signal of the magnetized, rapidly rotating M8.5 dwarf TVLM 513$-$46546. Methods: $R$- and $I$-band linear polarimetry images were collected with the ALFOSC instrument of the 2.56-m Nordic ...

Exploring the surface properties of Transneptunian Objects and Centaurs with polarimetric FORS1/VLT observations

open access: yes, 2006
Polarization is a powerful remote-sensing method to investigate solar system bodies. It is an especially sensitive diagnostic tool to reveal physical properties of the bodies whose observational characteristics are governed by small scatterers (dust ...

New symplectic V-manifolds of dimension four via the relative compactified Prymian [PDF]

open access: yes, 2007
Three new examples of 4-dimensional irreducible symplectic V-manifolds are constructed. Two of them are relative compactified Prymians of a family of genus-3 curves with involution, and the third one is obtained from a Prymian by Mukai's flop.

Electromagnetic field with constraints and Papapetrou equation

open access: yes, 2006
It is shown that geometric optical description of electromagnetic wave with account of its polarization in curved space-time can be obtained straightforwardly from the classical variational principle for electromagnetic field.

Imaging Optically-Thin Hot Spots Near the Black Hole Horizon of Sgr A* at Radio and Near-Infrared Wavelengths

open access: yes, 2005
Sub milli-arcsecond astrometry and imaging of the black hole Sgr A* at the Galactic centre may become possible in the near future at infrared and sub-millimetre wavelengths. Motivated by observations of short-term infrared and X-ray variability of Sgr A*,
