Liquid Phase Exfoliation of Nonlayered Non-Van der Waals Iron Trifluoride (FeF3) into 2D-Platelets for High-Capacity Lithium Storing Cathodes
(2022)Developing high-performance cathode materials for lithium-ion batteries is necessary to maximise both energy and power density. One promising cathode material is iron trifluoride (FeF3) having a high theoretical capacity ... -
Liquid phase exfoliation of two dimensional crystals

Liquid Processing of Interfacially Grown Iron-Oxide Flowers into 2D-Platelets Yields Lithium-Ion Battery Anodes with Capacities of Twice the Theoretical Value
(2022)Iron oxide (Fe2O3) is an abundant and potentially low-cost material for fabricating lithium-ion battery anodes. Here, the growth of α-Fe2O3 nano-flowers at an electrified liquid–liquid interface is demonstrated. Sonication ... -
Liquid-Phase Exfoliation of Nanotubes and Graphene
(2009)Many applications of carbon nanotubes require the exfoliation of the nanotubes to give individual tubes in the liquid phase. This requires the dispersion, exfoliation and stabilisation of nanotubes in a variety of liquids. ... -
Liquid-Phase Exfoliation of Nonlayered Non-Van-Der-Waals Crystals into Nanoplatelets
(2023)For nearly 15 years, researchers have been using liquid-phase exfoliation (LPE) to produce 2D nanosheets from layered crystals. This has yielded multiple 2D materials in a solution-processable form whose utility has been ... -
Local Electrical Imaging of Tetragonal Domains and Field-Induced Ferroelectric Twin Walls in Conducting SrTiO3
(2016)We demonstrate electrical mapping of tetragonal domains and electric field-induced twin walls in SrTiO 3 as a function of temperature and gate bias utilizing the conducting LaAlO 3 = SrTiO 3 interface and low-temperature ... -
Local electronic properties of carbon nanotube heterojunctions
(2000)Local electronic properties of metallic-semiconducting carbon nanotube heterostructures are investigated by studying the behavior of the one-electron local density of states ~LDOS! along the tubes. We determine how these ... -
Local inversion of the chemical environment representations
(2022)Machine-learning generative methods for material design are constructed by representing a given chemical structure, either a solid or a molecule, over appropriate atomic features, generally called structural descriptors. ... -
Local investigations of switchable rotaxane molecules at interfaces using atomic force microscopy
(Trinity College (Dublin, Ireland). School of Physics, 2008)Rotaxane molecules (interlocked molecules consisting of two parts bonded mechanically) have an inherent multi-stability. The relative positions of the submolecular components can be altered through external stimuli, a ... -
Localised surface plasmon mediated energy transfer in quantum dot systems
(Trinity College (Dublin, Ireland). School of Physics, 2015)Nonradiative energy transfer to metal nanoparticles (NPs) is a technique used for optical- based distance measurements which is often implemented in sensing. Both Forster resonant energy transfer (FRET) and nanometal surface ... -
Localized basis approach to many-body effects and dielectric response
(Trinity College (Dublin, Ireland). School of Physics, 2001)This thesis is a study of the optical and dielectric properties of semiconductors and insulators, and of the way in which these properties provide insight into the microscopic response of the interacting system. The central ... -
LOFAR Observations of Shocks in the Solar Corona
(Trinity College Dublin. School of Physics. Discipline of Physics, 2022)The Sun can produce large-scale energetic events such as solar flares and coronal mass ejections, which can excite shock waves that propagate from the low solar atmosphere into interplanetary space. Such shocks can result ... -
LOFAR observations of the quiet solar corona
(2018)Context. The quiet solar corona emits meter-wave thermal bremsstrahlung. Coronal radio emission can only propagate above that radius, Rω, where the local plasma frequency equals the observing frequency. The radio interferometer ... -
LOFAR tied-array imaging and spectroscopy of solar radio bursts
(Trinity College (Dublin, Ireland). School of Physics, 2016)The Sun is the source of the most powerful explosions in the solar system such as solar ares and coronal mass ejections (CMEs). These explosions can occur up to several times per day and they release up to 1032 ergs (1025 ... -
Logarithmic growth of local entropy and total correlations in many-body localized dynamics
(2020)The characterizing feature of a many-body localized phase is the existence of an extensive set of quasi-local conserved quantities with an exponentially localized support. This structure endows the system with the signature ... -
Long-chain amine-templated synthesis of gallium sulfide and gallium selenide nanotubes
(2016)We describe the soft chemistry synthesis of amine-templated gallium chalcogenide nanotubes through the reaction of gallium(iii) acetylacetonate and the chalcogen (sulfur, selenium) using a mixture of long-chain amines ... -
Long-range charge order on the Fe3O4(001) surface
(American Physical Society, 2004)The Verwey transition in magnetite is of fundamental importance for the understanding of metal-insulator transitions but, in spite of being the subject of many studies over the last century, its nature is not fully understood. ... -
Long-range magnetic coupling across a polar insulating layer
(2016)Magnetic interactions in solids are normally mediated by short-range exchange or weak dipole fields. Here we report a magnetic interaction that can propagate over long distances (∼10 nm) across a polar insulating oxide ... -
Long-ranged dynamic magnetic interaction through low-dimensional systems
(American Physical Society, 2008)Magnetic units attached to low-dimensional metallic nanowires are known to interact via the conduction electrons of the wire leading to preferential alignment directions of the respective magnetic moments. In addition to ...
