Next generation optoelectronic devices for energy applications utilising metal oxides, bismuth oxyhalides and lead halide perovskites
… part of the thesis examines bismuth oxyiodide (BiOI) as an alternative to LHP. LHP are limited by the presence of lead, which is toxic and bio-accumulative. By contrast, bismuth-based compounds have little evidence of toxicity and the related BiOCl compound is used in medicines. BiOI was chosen …

Developing next generation, non-toxic, inorganic materials for photovoltaics and thin-film transistors
… of low-power, efficient electronic devices. BiOI, a non-toxic, perovskite-inspired material is investigated for photovoltaics (PVs) whilst Cu<sub>2</sub>O, with a reasonably high predicted hole mobility is developed for *p*-type thin-film transistors (TFTs). These novel materials are …

Vapour-based growth of inorganic compounds for next-generation, stable photovoltaics
… recombination across the bandgap. BiOI is identified as a promising photovoltaic material amongst compounds such as methylammonium bismuth iodide and bismuth-based double perovskite structured compounds due to its relatively favourable bandgap (1.9 eV), small predicted electron and …

Bismuth Oxyhalide Nanosheets with Adjustable Band Edge Potentials for Photocatalytic Ammonia Generation
… the studied photocatalysts, bismuth iodide (BiOI) showed promising properties such as visible light absorption capability, adjustable band edge potentials, and abundant surface oxygen vacancies to activate nitrogen molecules. In the third chapter, we fabricated ultrathin BiOI nanosheets by a …

Biotin synthesis in Bacillus subtilis
… and biochemical studies identified bioW and bioI as two genes required for pimeloyl-CoA and pimeloyl-ACP synthesis, respectively. The question of the significance of each gene is striking due to the redundancy of pimelate thioester generation. BioW, a structurally unique enzyme, remained to …

Transient Photophysics of Bismuth Halide Semiconductors for Optoelectronic Applications
… of thin films of layered bismuth oxyiodide, BiOI, have a great degree of energetic disorder, most likely due to the presence of self-trapped excitons and defect states. Transient absorption measurements give an excited state lifetime of 47 ps, which would make efficient photovoltaic …

Static and Dynamic Disorder in Emerging Optoelectronic Materials
… bismuth triiodide (BiI3) and bismuth oxyiodide (BiOI), that exhibit promising optoelectronic properties for PV applications. Here we use a combination of DFT and many-body theory together with finite differences as well as transient spectroscopy to show, that BiI3 is an intrinsically poor …

Water stress protein is secreted, is subject to rapid proteolysis upon rehydration of desiccated cells, and may be glycosylated
… commune</i> (Scherer, S. and Potts, M. 1989. J. BioI. Chem. 264:12546-12553). In the original study, several inconsistencies were noted and are addressed in this body of work. Firstly, the microheterogeneity noted on two dimensional electrophoresis gels indicated the possibility of modifications …

Ultrastructural studies of cornea and sclera
The work of Goodfellow et al., (J. Mol. BioI. 119: 231. 1918) and Sayers et al., (J. Mol. BioI. 160: 593. 1982), was repeated using fresh, equilibrated cornea, confirming their finding that the plot of interfibrillar spacing against liydration is a linear relationship. Intermolecular spacing in …

BISMUTH-FUNCTIONALIZED SORBENTS FOR RADIOIODINE CAPTURE
… with only a small amount of iodine captured as BiOI (18 mass%). After aging TEO-5 for 3 h, iodine was captured as both BiI3 (26%) and BiOI (74%) and no Bi2O3 was detected. The iodine captured sorbents were leached with water to simulate a flooded situation. A steady increase in iodine …

Polyaseeker: a computational framework for identifying polyadenylation cleavage site from RNA-seq
… polyadenylated RNAs. However, no comprehensive bioi nformatic pipelines have fulfilled this goal. The PolyASeeker, a computational framework for identifying polyadenylation cleavage sites from RNA-Seq data is proposed in this thesis. By using the simulated RNA-seq dataset, a novel method is …

Anodic films on Bismuth
… contained iodide at low pH, when the oxo-iodide, BiOI, was probably formed. Room lighting had no effect on the cyclic voltammetric or galvanostatic measurements. The transient response of anodic films on bismuth to an intense flash of white light was studied. In the case of a thick anodic oxide …
