Organic light-emitting diodes (OLEDs) are poised to realize high performance for innovative display and lighting applications in the future. However, the development of suitable blue OLEDs remains a challenge which has impeded the progress of large-scale OLED commercialization for more than a decade. Blue devices are…
The surge of interest in multifunctional materials over the past 15 years has been driven by their fascinating physical properties and huge potential for technological applications such as sensors, microwave devices, energy harvesting, photovoltaic technologies, solid-state refrigeration, and data storage recording te…
The spatio-temporal distribution of microphytobenthos (MPB) on the sediment surfaces during emersions and suspended in water column during immersions was investigated on transects across Fingringhoe Tidal Flat in Colne estuary, on three zones: the mud flat, the transition zone and the salt marsh. The results of this t…
We respond to the erroneous criticisms about our modeling of proton transport in barium stannate [G. Geneste et al., Phys. Chem. Chem. Phys., 2015, 17, 19104]. In this previous work, we described, on the basis of density-functional calculations, proton transport in the classical and semi-classical regimes, and provide…
Recently, high-pressure science and technology has flourished and rapidly advanced to impact a wide domain of materials and physical sciences. One of the most substantial technological developments is the integration of samples at ultrahigh pressure with a wide range of in-situ probing techniques. Applications of extr…
A Doctoral Thesis. Submitted in partial fulfilment of the requirements for the award of Doctor of Philosophy of Loughborough University.
This dissertation presents a new path-dependent non-proportional multi-axial fatigue model which is formulated in an incremental form of moment of load path (MLP) on σ-√β τ plane, ε-√(β^ε ) γ plane or K plane (i.e K_I-√(β^K ) K_III plane), depending upon if fatigue evaluation is performed in terms of stress-life, stra…
Any pretreatment process used to enhance the enzymatic deconstruction of lignocellulosic substrates, although opening up and enhancing access to the cellulose, will typically generate inhibitory compounds (i.e. soluble mono/oligomeric sugars, phenolics, furans, extractives, etc.) that will limit or restrict the effici…
Accurate measurement of the properties, emission rates, and environmental impacts (i.e. climate forcing) of aggregated aerosols depend on precise measurement of their morphology (i.e. primary particle diameter, dp, and its polydispersity). For decades soot has been modeled as fractal-like aggregates of nearly equiaxed…
Transformation-induced plasticity (TRIP) steels are an example of steels used in the automotive industry, where strain-induced martensitic transformations, associated plasticity and work hardening, enhance both the strength and ductility of the material. This has enhanced both the passenger safety (improved crash-perf…
Die Silika-Biomineralisation in Kieselalgen wird vermutlich durch aggregierte Biomoleküle innerhalb der Silika-Ablagerungsvesikel kontrolliert. Die Struktur der gebildeten Zellwand wird dabei durch die Morphologie der organischen Vorlage definiert. Mehrere Studien haben sich bereits mit der Selbst- und Co-Aggregation…
Magnetic materials are used in the manufacturing of transformers, electrical machines, converters and inductors. The losses of the magnetic materials affect the performance of the electromagnetic devices. The magnetic components play an important role in dissipating the core losses in power electronics devices. Measur…
Through a combination of chemical and genomic data this study has demonstrated that "brown" alpacas are predominantly pheomelanic, and are similar to bay horses in colour phenotype. RNAseq was used to analyse colour genes the alpaca skin-transcriptome, and has provided the first annotation of the alpaca (vicPac2) geno…
The effectiveness of a liming material for neutralizing soil acidity depends mainly on its calcium carbonate (CaCO3) equivalent (CCE) and its fineness. The Iowa Department of Agriculture and Land Stewardship (IDALS) rules for agricultural lime (aglime) sales requires measuring Effective CCE (ECCE), which combines CCE…
This work does not limit itself to its title and touches on a number of related topics beyond it. Starting with the title, Polarization Aberrations of Optical Coatings, the immediate question that comes to mind is: what coatings? All coatings? Not all coatings, but just enough that a third person could take this infor…
The replacement of synthetic polymers with renewable content in emulsion polymerization latexes has been a focus of research over the past several decades. Emulsion polymerization is a more sustainable way to produce polymers for films and resins. Starch is a sustainably sourced material that has proven to be extremel…
A physically-based model for discontinuous dynamic recrystallization (DDRX) in metals is developed using a mean field approach. It couples together polyphase plasticity, grain growth and nucleation models to predict the macroscopic stress and grain size evolution during thermomechanical processing. A new nucleation mo…
As regulations for nitrogen oxide (NOx) emissions continue to be tightened, the need for both alternative fuels and intensive exhaust after-treatment will increase. n-Butanol as an alternative fuel has demonstrated the potential to reduce both NOx and particulate matter (PM) emissions, simultaneously. The use of n-but…
There exist multiple driving forces in solid–state materials that can be utilized for entropy changes and hence stronger caloric response. In multiferroic materials, adiabatic temperature changes (ΔTad) can be obtained via combined application of electric, stress, and magnetic fields. These external stimuli provide ad…
Multi-junction photovoltaic devices based on III-V semiconductors have applications in space power systems and terrestrial concentrating photovoltaics, as well as in power-over-fibre and optical power conversion systems. These devices have between two and twenty junctions arranged in tandem, connected in series with o…
