Alcohol Pre-treatment to Eliminate the Interference of Micro Additive Particles in the Identification of Microplastics Using Raman Spectroscopy
(2022)Raman spectroscopy is an indispensable tool in the analysis of microplastics smaller than 20 μm. However, due to its limitation, Raman spectroscopy may be incapable of effectively distinguishing microplastics from micro ... -
Crystallographic Characterisation of Ultra-Thin, or Amorphous Transparent Conducting Oxides ? The Case for Raman Spectroscopy
(2020)The electronic and optical properties of transparent conducting oxides (TCOs) are closely linked to their crystallographic structure on a macroscopic (grain sizes) and microscopic (bond structure) level. With the increasing ... -
Dataset asssociated to "Electrocatalysis of N-doped carbons in the oxygen reduction reaction as a function of pH: N-sites and scaffold effects"
(Trinity College Dublin, 2019)Dataset associated to "Electrocatalysis of N-doped carbons in the oxygen reduction reaction as a function of pH: N-sites and scaffold effects" -
Defect-moderated oxidative etching of MoS<inf>2</inf>
(2019)We report a simple technique for the selective etching of bilayer and monolayer MoS 2. In this work, chosen regions of MoS 2 were activated for oxygen adsorption and reaction by the application of low doses of He + at 30 ... -
Growth of 1T′ MoTe2 by Thermally Assisted Conversion of Electrodeposited Tellurium Films
(2019)Molybdenum ditelluride (MoTe2) is a transition metal dichalcogenide (TMD) which has two phases stable under ambient conditions, a semiconducting (2H) and semimetallic (1T′) phase. Despite a host of interesting properties ... -
Highly emissive nanowires grown from CdTe nanocrystals in a phosphate buffer solution
(2005)We present details on the CdTe nanowires formation, which were found to grow in a standard physiological phosphate-buffered solution, including in-situ observation of growth with a confocal microscope. The choice of ... -
The influence of drinking water constituents on the level of microplastic release from plastic kettles
(2022)Microplastic (MP) release from household plastic products has become a global concern due to the high recorded levels of microplastic and the direct risk of human exposure. However, the most widely used MP measurement ... -
Investigation of correlation between characteristics of Raman spectra and parameters of data-scattering obtained from phase coherence theory
(SPIE, 2005)The importance of sensitive monitoring of changes in Raman spectra in particular for microelectronic applications is discussed here. We explore the practicality of using a data-scattering method to analyse Raman spectra, ... -
Investigation of growth-induced strain in monolayer MoS2 grown by chemical vapor deposition
(2020)Two-dimensional materials such as transitional metal dichalcogenides exhibit unique optical and electrical properties. Here we report on the varying optical properties of CVD grown MoS2 monolayer flakes with different ... -
Measurement of Degree of Order in Mixed Polarised Fluorescent Polymer Liquid Crystal Films
(1998)Raman spectroscopy is used to investigate the degree of order found in in situ photopolymerised films exhibiting polarised emission. Studies indicate that the mixed system shows differing degrees of order for its two ... -
Optical properties of diamond films grown by MPCVD method with alternating nanodiamond injection
(Society of Photo-optical Instrumentation Engineers (SPIE), 2005)Transparent polycrystalline diamond films with grain size ranging from a few tens to hundreds of nanometres were prepared on fused silica substrate by Microwave Chemical Plasma Vapour Deposition method (MPCVD). The ... -

Preparation and characterisation of metallorganic precursors derived iron oxides on porous silicon layers
(Trans Tech Publications Ltd., Switzerland, 2020)Porous silicon has generated interest in scientific community after its photoluminescence discovery and thereafter, research was focused on to the chemical functionalization of silicon and subsequent anchoring of nanoparticles ... -
Raman investigation of different polytypes in SiC thin films grown by solid-gas phase epitaxy on Si (111) and 6H-SiC substrates
(2010)Raman spectroscopy was applied to investigate a series of SiC films grown on Si and 6HSiC substrates by a new method of solid gas phase epitaxy. During the growth characteristic voids are formed in Si at the SiC/Si ... -
Spectroscopical analyis of strained silicon quantum wells
(SPIE, 2005)In this study, Strained silicon Quantum Wells (QW) were characterised using a variety of micro-scopical techniques. Among the techniques used were Transmission Electron Microscopy (TEM), Elemental Electron Loss ... -
Stability and capping of magnetite ultra-thin films
(2014)Ultrathin films of Fe3O4 have been grown epitaxially on nearly lattice matched MgO(001). The stability of 4 nm thick films in ambient air and under annealing in an oxygen atmosphere at 200◦C has been studied. By magneto ... -
Synthesis and Characterisation of Transition Metal Dichalcogenides and their Heterostructures
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2021)Since the first isolation of graphene in 2004 the interest in 2D materials has exponentially grown. Two-dimensional layered materials demonstrate profoundly different properties when isolated in their mono- or few layer ...
