Processing and Properties of Multifunctional Polylactide/Graphene Composites
(Queen Mary University of London, 2017-11-15)This thesis aims to utilize graphene nanoplatelets (GNPs) in biobased and biodegradable thermoplastic polylactide (PLA) matrix for improved properties and multifunctionalities. A comprehensive comparative study was carried ... -
Processing and Sintering of Carbonate Hydroxyapatite
(Queen Mary University of London, 1995)Since the early 1970's there have been a number of investigations into the preparation of dense sintered hydroxyapatite for medical applications. However, there have been few studies reporting the production of ... -
Processing and switching mechanism of ferroelectric copolymer P(VDF/TrFE)
(Queen Mary University of London, 2016-02-04)The processing and properties of the ferroelectric copolymer P(VDF/TrFE) was investigated in this work, and is divided into two main parts. The first part focused on different processing routes, and the second part focused ... -
Processing of Cargo Proteins By The Type IX Secretion System.
(Queen Mary University of London., 2021-03-25)Porphyromonas gingivalis is a Gram-negative oral anaerobic pathogen and is one of the key causative agents of the periodontitis. P. gingivalis utilises a range of virulence factors to drive pathogenesis that are exported ... -
Processing of Polymer-based Systems for Improved Performance and Controlled Release
(Queen Mary University of London, 2011-10)This thesis focuses on i proved processing methods for enhanced mechanical properties in polymer nanocomposites, and controlled drug release in polymer based delivery systems. Supercritical carbon dioxide assisted mixing ... -
Processing organic semiconductors
(2010)In recent years, there has been a considerable interest in organic semiconducting materials due to their potential to enable, amongst other things, low-cost flexible opto-electronic applications, such as large-area integrated ... -
Processing, Structure and Ferroelectric Properties of PVDF-Based Ferroelectric Polymers
(Queen Mary University of London, 2017-07-04)Polyvinylidene fluoride (PVDF) and its copolymer with trifluoethylene (PVDF-TrFE) have been widely investigated. This is largely attributed to their ferroelectric properties, which are present in a limited number of polymers. ... -
Producing the Festival City: Place Myths and the Festivals of Adelaide and Edinburgh
(Queen Mary University of London, 2015-10-13)The Edinburgh International Festival (EIF) and the Adelaide Festival, and their associated Fringe Festivals, are large international multi-‐arts events that focus on artistic excellence and annually imbue their host cities ... -
PRODUCTION AND ASSESSMENT OF OVINE ANTIVENOMS FOR THE TREATMENT OF SNAKE ENVENOMING IN SAUDI ARABIA
(Queen Mary University of London, 1996)Venoms from the most poisonous snakes found in Saudi Arabia were assessed for their physical and chemical characteristics and for their enzymatic and biological activities. Venom from Atractaspis microlepidota was the most ... -
Production and characterization of reinforced hydroxyapatite for bone replacement.
(Queen Mary University of London, 2001)Hydroxyapatite(HA) is a highly biocompatible calcium phosphate material which in porous form, promotes rapid bone ingrowth and revascularisation. As such it has potential for use as a synthetic bone graft substitute. ... -
The Production and Use of Proton-Induced Ultrasoft X-rays
(Queen Mary University of London, 1988)A 700 keV Van de Graaff accelerator was used to accelerate protons onto solid targets of different light elements to produce ultrasoft, characteristic X-rays (< 5 keV). The proton energies were calibrated using the (p, ... -
Production of retinoic acid by antigen presenting cells in the healthy and inflamed human intestine.
(Queen Mary University of London, 2013-09)Murine small intestinal CD103+ dendritic cells (DCs) produce retinoic acid (RA) through retinaldehyde dehydrogenase (RALDH) activity, thereby inducing ‘gut-homing’ α4β7 and CCR9 on T cells they activate, enhancing ... -
Professionalism in dental education: Perceptions and influences on development of learners
(Queen Mary University of London, 2016-05-25)The General Dental Council in its latest educational review placed professionalism at the heart of its education agenda and developed corresponding learning outcomes (GDC, 2015). This interpretivist qualitative study aimed ... -
Professionally applied Fluoride Paint-On Solutions (PAFS): Closing the Gaps in the Evidence Base for the Appropriate Use of Topical Fluorides
(Queen Mary University of London, 2014-08-15)Aims To identify the gaps in the evidence-base for topical fluoride therapies (TFT) for caries and, to assess the effectiveness, safety and economic value of paint-on fluoride solutions (PAFS) for caries control. Methods Three ... -
Profiling circulating tumour DNA for tracking tumour dynamics in pancreatic cancer
(Queen Mary University of London, 2021)The potential of circulating tumour DNA (ctDNA) for tumour monitoring in pancreatic ductal adenocarcinoma (PDAC) has not been fully realised beyond mutation tracking of known KRAS variants. Here, we aimed to characterise ... -
