In vitro localisation and degradation of few-layer MoS2 submicrometric plates in human macrophage-like cells: a label free Raman micro-spectroscopic study
(2020)
Monitoring the uptake, micro-environment and fate of micro or nano scaled particulate materials in cells is of paramount importance for the emerging fields of toxicology and medicine. Such particulate materials are known ...
Preparation and characterisation of carbon nanotube films and composites
(Trinity College (Dublin, Ireland). School of Physics, 2008)
A simple method of carbon nanotube (NT) composite preparation has been
demonstrated that produces wide ranging and extremely high carbon nanotube mass
fraction, mf, composites with minimal reagregation of the nanotubes (up ...
A facile "bottom-up" approach to prepare free-standing nano-films based on manganese coordination clusters
(2013)
We present herein a novel method to prepare free-standing Dried Foam Films (DFFs) whereby individual polynuclear manganese complexes cover quantitatively the holes of micro-grids; the fabricated, homogeneous films have a ...
An experimental investigation into the conversion of optical spin to orbital angular momentum using internal conical diffraction
(Trinity College (Dublin, Ireland). School of Physics, 2010)
Internal conical refraction (ICR) transforms a ray incident upon the optic axis of a biaxial crystal into a cone of light within the medium and a hollow cylinder of light upon exiting. If the incident ray is circularly ...
Propagation of coronal mass ejections in the inner heliosphere
(Trinity College (Dublin, Ireland). School of Physics, 2011)
Solar Coronal mass ejections (CMEs) are large-scale ejections of plasma and magnetic field from the corona, which propagate through interplanetary space. CMEs are the most significant drivers of adverse space weather on ...
Metal Nanoparticle Film Deposition by Femtosecond Laser Ablation at Atmospheric Pressure
(2020)
Nanoparticle gold films were deposited using femtosecond laser ablation in argon at atmospheric pressure in an arrangement where a flat Au target was irradiated through a transparent substrate in close proximity. Spatially ...
Morphological influences on the excited state dynamics of conjugated polymers
(Trinity College (Dublin, Ireland). School of Physics, 2000)
A series of soluble phenylene vinylene copolymers have been prepared by four different methods. Two of these methods use the Wittig reaction in toluene and DMF, whereas the other two were prepared by the Horner reaction ...
Solar Magnetic Feature Detection and Tracking for Space Weather Monitoring
(2011)
We present an automated system for detecting, tracking, and cataloging emerging active regions throughout their evolution and decay using SOHO Michelson Doppler Interferometer (MDI) magnetograms. The SolarMonitor Active ...
Deformation and Yield of Polymer Thin Films in Confined Geometries
(Trinity College Dublin. School of Physics. Discipline of Physics, 2019)
Polymer thin film mechanics represents a hugely promising field of research. Due to their versatility and ease of fabrication, polymer films and coatings rank among the most ubiquitous systems in all of nanotechnology. The ...
Label-free screening of biochemical changes in macrophage-like cells following MoS2 exposure using Raman micro-spectroscopy
(2021)
The emergence of large scale production techniques for 2D particulate materials has dramatically increased their applications potential. Understanding the interactions of biological cells with such particulate material is ...
