to act as spin filtering barriers
in magnetic tunnel junctions. Our study is based on the electronic structure calculated by ...
Imaging and identification of point defects in PtTe2
(2021)
The properties and performance of two-dimensional (2D) materials can be greatly affected by point defects. PtTe2, a 2D material
that belongs to the group 10 transition metal dichalcogenides, is a type-II Dirac semimetal, ...
Influence of magnetic field on hydrogen reduction and co-reduction in the Cu/CuSO4 system
(2010)
The effects of an applied magnetic field of up to 5 T on hydrogen evolution and cathodic overpotential were studied for H2SO4 and an acidic Cu/CuSO4 system. Cyclic voltammetry, potentiostatic and galvanostatic deposition ...
Three-dimensional models of astrophysical magnetohydrodynamical jets
(Trinity College (Dublin, Ireland). School of Physics, 2007)
In the previous fifty years it has become clear that jets and outflows play a vital role in the formation of stars and com pact objects. Jets from young stellar objects typically show Herbig-Haro
knots and bow shocks. ...
Mechanically alloyed Sm-Co hard magnetic materials
(Trinity College (Dublin, Ireland). School of Physics, 2002)
In the recent search for new high-temperature permanent magnet materials, research has concentrated on bulk Sm2Co17-type magnets. The usual approach to development of coercivity in bulk Sm-Co based materials is to prepare ...
A solar-like magnetic cycle on the mature K-dwarf 61 Cygni A (HD 201091)
(2016)
Context. The long-term monitoring of magnetic cycles in cool stars is a key diagnostic in understanding how dynamo generation and amplification of magnetic fields occur in stars similar in structure to the Sun.
Aims. ...
CdTe Quantum Dot/Dye Hybrid System as Photosensitizer for Photodynamic Therapy
(2010)
We have studied the photodynamic properties
of novel CdTe quantum dots?methylene blue hybrid
photosensitizer. Absorption spectroscopy, photolumines-
cence spectroscopy, and fluorescence lifetime imaging of
this system ...
Effects of M dwarf magnetic fields on potentially habitable planets
(2013)
We investigate the effect of the magnetic fields of M dwarf (dM) stars on potentially habitable Earth-like planets. These fields can reduce the size of planetary magnetospheres to such an extent that a significant fraction ...
Growth Laws for the Phase-ordering Dynamics of the B1 Phase of a Bent-core Liquid Crystal
(2004)
We have experimentally investigated the dynamics of the phase ordering process of bent-core molecules at isothermal conditions, forming the liquid crystalline ?banana? B1 phase from the isotropic melt. In contrast to the ...
