Ex-ante viability of wonder nanomaterials from waste CO2: An ex-ante techno-economic and environmental assessment of CO2 based carbon nanomaterial production and comparison with status quo

The primary objective of this study was to address the lack of understanding of the commercial- scale implementation of novel CO2 based carbon nanomaterial (CNM) production and its comparison with status quo CNM production processes using unsustainable fossil resources. To accomplish this objective, first, a literature review was performed on...

Manufacturing and Mechanical Testing of Composite T-Joints with Carbon Nanotube Interleaves

In recent decades, fibre-reinforced polymer composite structures have seen increased aerospace applications. A typical composite structural element widely used in primary load-bearing aircraft components is the T-joint, which is formed when two orthogonal laminates are joined in a T-shaped arrangement to enable out-of-plane load transfer. Under...

High aspect ratio surface micro-machining using carbon nanotubes

Silicon-based MEMS technology has been the standard for developing 2D and 3D<br/>micro-structures for many years. There are 2 main classifications of MEMS manufacturing technologies, viz. bulk micro-machining, and surface micro-machining.<br/>These techniques have its own set of drawbacks. Bulk micro-machining affects the structural integrity of...

Flexible Interposer Based on Carbon Nanotubes and PDMS Composite

A new method of flexible interposer with vertically aligned carbon nanotube (CNT) embedded in polymer is proposed in this thesis. Interposer, working as electrical routing between different sockets or connections, is being used for spreading connections and rerouting in packaging technology nowadays. With the rapid growing application of...

Fabrication and characterization of an Upside-down CNT MEA

Over the last few years the need of new alternatives to traditional disease modelling, drug screening and toxicity tests has boosted the development of a new class of devices called Organ on Chip. These usually consist in a substrate or a well in which cells are cultured with the aim of differentiating them in a particular tissue lineage. With...

Super-growth of CNTs based on ZrN for TSV application

This thesis has explored the possibility of using carbon nanotubes (CNT) as a novel material for through-silicon vias (TSV) in 3D-integrated circuits. With the steady downscaling trend of the semiconductor industry, a major limiting factor to the overall performance of the device is the delay from interconnects; a trend that is worsening over...

Carbon nanotubes as vertical interconnects in 3D integrated circuits

In integrated circuits the delay caused by interconnects, their power consumption, production and reliability are challenges to be solved. Using the third dimension for additional layers of transistor has been proposed as a solution to this problem by reducing the length of the interconnects. A problem in 3D integration is the creation of...
