Abstract:

A number of pathological conditions are associated with the build up of toxic substances within the systemic circulation. For example, renal and hepatic failure can lead to the accumulation of metabolites which are usually processed by these organs. There has been much interest over a number of years in techniques such as haemoperfusion that could help clear these toxins from the body and improve patient outcome. Haemoperfusion is an extracorporeal blood purification technique in which a patient’s blood is passed over a column containing a material designed to adsorb a board spectrum of biolog

Abstract:

This project was basically exploratory in the electrical properties of carbon nanotube (CNT) based materials. The direct current (DC) conductivity of CNT/polymer composites was computed by using equivalent circuit method and a three dimensional (3-D) numerical continuum model with the consideration of tunneling conduction. The effects of the potential barrier of polymer and the tortousity of CNTs on the conductivity were analyzed. It was found that both of percolation threshold and DC conductivity can be strongly affected by the potential barrier and the tortousity. The influence of contact re

Abstract:

Carbon nanofillers such as graphite nanoplatelets (GNPs) and vapour grown carbon nanofibres (VGCNFs) have enormous potential for developing thermal interface materials (TIMs), mainly due to their high thermal conductivity. In this project GNPs, VGCNFs and carbon black (CB) fillers were dispersed in the compliant polymer matrices, rubbery epoxy and silicone, to form composites. Mechanical mixing, dual asymmetric centrifuge speed mixing, three-roll milling or combined sonication and solvent mixing were used to produce composites.

Graphene is a monolayer of carbon atoms with remarkable electronic and mechanical properties. The attractive electronic properties of thin and thick films made of carbon nanotubes (CNTs) and graphene are increasingly being exploited for environmental and biological sensors. In particular, their sensitivity, selectivity, fast response time, ability to operate at room temperature, and their passive nature (no power consumption) provide competitive advantages of CNTs in sensor applications. However, their design as RF wireless sensors requires the integration of an antenna with the sensor elemen

Carbon concrete polyacrylonitrile (PAN)/lignin-based carbon fiber (CF) composites are a new promising material class for the building industry. The replacement of the traditional heavy and corroding steel reinforcement by carbon fiber (CF)-based reinforcements offers many significant advantages: a higher protection of environmental resources because of lower CO2 consumption during cement production, a longer lifecycle and thus, much less damage to structural components and a higher degree of design freedom because lightweight solutions can be realized.

Abstract:

Optimal conditions were found for the formation of carbon-oxide composites by the treatment of mixtures of oxides of aluminum or titanium with carbon nanotubes and nanofibers in a planetary ball mill. The dependences of the electrical conductivity of composites on the content of carbon nanomaterials (1-5% by mass) were determined. It is shown that the addition of 3%(wt) of CNT to the oxides leads to a sharp increase in the electrical conductivity: from 5.0×10-8 to 2.8×10-4 S/cm for Al2O3 and from 5.0×10-6 to 2.2×10-2 S/cm for TiO2.

The areas where C/C composites are being used extensively are aerospace, military, etc. These C/C composites have better physical, mechanical, thermal properties when compared to steel.

Abstract:

The overall research theme of this dissertation was the study of nanoparticle/polymer composites. Two types of nanoparticles were utilized: Single-Walled Carbon Nanotubes and quantum dots. Chapter 1 of this thesis comprises an extensive literature review on Carbon Nanotubes, which presents theoretical aspects relevant to the structure and properties of CNTs, methods of purifying and solubilizing CNTs in aqueous and organic solvents and selected applications. This literature review is followed by the study and comparison of the optical limiting performances of different Single-Walled Carbon

Abstract:

The present thesis is to be brought into line with the current need for alternative and sustainable approaches toward energy management and materials design. In this context, carbon in particular has become the material of choice in many fields such as energy conversion and storage. Herein, three main topics are covered: 1)An alternative synthesis strategy toward highly porous functional carbons with tunable porosity using ordinary salts as porogen (denoted as “salt templating”) 2)The one-pot synthesis of porous metal nitride containing functional carbon composites 3)The combination of both ap

Abstract:

A study was carried out on formulations of organic-inorganic hybrids and their subsequent use as matrices for unidirectional carbon fibre-reinforced composites. The hybrids consist of low molecular weight polyimide precursors and silica which is generated in-situ via the sol-gel route. A special feature of these systems is the use of organofunctional trialkoxysilanes as coupling agents for the two phases and for controlling the resultant morphology. Enhancements are obtained in physicochemical, thermal and mechanical properties of hybrids through morphological modifications achieved in the par
