Non-equilibrium gas-phase nitrogenation
(IEEE, 1994)
Non-equilibrium nitrogenation of
transition-metal rich rare-earth intermetallics can
be used to increase the nitrogen content beyond its
equilibrium concentration. For example, nitrogenation
of Sm2Fel7 using ammonia ...
Polarization resolved four-wave-mixing-based measurement in bulk material semiconductor optical amplifier
(2006)
The anticipated growth in demand for bandwidth leads to the development of all-optical signal processing techniques at ever increasing data rates. One possible candidate to achieve the required performance is the semiconductor ...
Tuneable Piezoresistance of Graphene-Based 2d:2d Nanocomposite Networks
(2023)
Piezoresistive nanocomposites are an important class of materials that allow the production of very sensitive strain sensors. Herein, a new class of piezoresistive nanocomposites prepared by mixing different types of 2D ...
Studies of gain and lasing in thulium doped fibres
(Trinity College (Dublin, Ireland). School of Physics, 2006)
Rare earth ions have absorption and emission lines in almost the entire transparent
region of silica optical fibres, and they can be used as dopants inside the fibre core of
single mode optical fibres employed for ...
Non-linear optical properties of Group 10 metal alkynyls and their polymers
(1991)
Conjugated diacetylene and phenylacetylene systems incorporating Group 10 transition-metal complexes have been obtained via lithium acetylide intermediates. In the UV?VIS spectra, the positioning of the longest-wavelength ...
1.3 μm wavelength tunable single-mode laser arrays based on slots
(2021)
Two twelve-channel arrays based on surface-etched slot gratings, one with non-uniformly spaced slots and another with uniformly spaced slots are presented for laser operation in the O-band. A wavelength tuning range greater ...
Effect of molecular conformations on the electronic transport in oxygen-substituted alkanethiol molecular junctions
(2018)
The relationship between the molecular structure and the electronic transport properties of molecular junctions based on thiol-terminated oligoethers, which are obtained by replacing every third methylene unit in the ...
Current-induced phonon renormalization in molecular junctions
(2016)
We explain how the electrical current flow in a molecular junction can modify the vibrational spectrum
of the molecule by renormalizing its normal modes of oscillations. This is demonstrated with first-principles
self-consistent ...
Reinforcement of metal with liquid-exfoliated inorganic nano-platelets
(2013)
We have prepared metal matrix composites (MMCs) of a pewter alloy filled with liquid-exfoliated Molybdenum Telluride (MoTe2) nano-platelets. The combination of MoTe2 and pewter was chosen due to their near-identical ...
