Effect of copper on the magnetism of half doped bilayer manganite
We have studied the effect of substituting copper at the manganese site on the structure, resistivity and magnetism of the bilayer manganite LaSr2Mn2-xCuxO7 (0
A Facile Surfactant-Assisted Reflux Method for the Synthesis of Single-Crystalline Sb2Te3 Nanostructures with Enhanced T...
Antimony telluride (Sb2Te3) and its based alloys are of importance to p-type semiconductors for thermoelectric applications near room temperature. Herein, we report a simple, low-energy intensive, and scalable surfactant-assisted reflux method for the synthesis of Sb2Te3 nanoparticles in the solvent ethylene glycol (EG) at low temperatures (120-180...
The roles of hydration and evaporation during the drying of a cement paste by localized NMR
The moisture distribution during the setting of a thin mortar layer can be particularly complex to manage under dry (20% RH) and hot weather (above 25 degrees C) conditions. To better understand the fundamental phenomena at stake, we used static gradient relaxation NMR tools such as Profile MOUSE and STRAFI. This allowed disentangling the mutual ef...
On the Influence of Molecular Structure on the Conductivity of Electrolyte Solutions – Sodium Chloride in Dioxane–Water ...
Published in Zeitschrift für Physikalische Chemie
Theoretical calculations of the conductivity of sodium chloride in water + 1,4-dioxane mixtures are presented and compared with experimental measurements. The method of direct correlation force in the framework of the interionic theory is used for the calculation of transport properties in connection with the associative mean spherical approximatio...
Strain-tunable band gap in graphene/h-BN hetero-bilayer
Using full-potential density functional calculations within local density approximation (LDA), we predict that mechanically tunable band-gap and quasi-particle-effective-mass are realizable in graphene/hexagonal-BN hetero-bilayer (C/h-BN HBL) by application of in-plane homogeneous biaxial strain. While providing one of the possible reasons for the ...
A chemo-poro-mechanical model of oilwell cement carbonation under CO2 geological storage conditions
A poromechanical model is developed to identify how chemical reactions of carbonation may impact the mechanical behaviour of wellbore cement in the context of CO2 storage. The model enables evaluating pore overpressure, porosity and solid skeleton strain evolutions during the carbonation process. The major chemical reactions occurring within cement...
Charged Dilatonic Black Holes and their Transport Properties
We briefly explain the consistency conditions imposed on the effective holographic theories, which are parameterized by two real exponents $(\gamma,\delta)$ that control the IR dynamics. The general scaling of DC resistivity with temperature at low temperature and AC conductivity at low frequency across the whole $(\gamma,\delta)$ plane are explain...

Spin-orbit interaction induced anisotropic property in interacting quantum wires
We investigate theoretically the ground state and transport property of electrons in interacting quantum wires(QWs) oriented along different crystallographic directions in(001) and(110) planes in the presence of the Rashba spin-orbit interaction(RSOI) and Dresselhaus SOI(DSOI). The electron ground state can cross over different phases, e.g., spin d...
Effect of gas pressure on the properties of silicon thin film
A series of transition films from amorphous to microcrystalline silicon was successfully prepared by very high frequency plasma enhanced chemical vapor deposition(VHF-PECVD).Effects of gas pressure on the microstructure, photoelectric and transport properties of the films were investigated.The results indicate that increase of gas pressure improve ...
