Alvin (Dr.Orb), a Senior Lecturer at the Energy Safety Research Institute (ESRI) has a vision is to advance global energy sustainability by developing efficient and equitable materials and methods of transmitting electricity. He develops new ways to produce and use carbon nanomaterials, while building a community of researchers to engage the issue. He aims to impact the environment both locally and globally via a two-fold approach:

  1. Improve the energy infrastructure using carbon nanotubes to transmit electricity
  2. Turn carbon waste into higher-value products such as carbon nanotubes

He completed a PhD at Rice University, USA, on the catalytic growth of single-walled carbon nanotubes. He post-doc'd at the Massachusetts Institute of Technology (MIT).

His research uses a circular economy philosophy to close the loop on the carbon cycle, his motto is to "leave no carbon behind". He is creating technologies to use multiple plastic types, in single processes, that generate higher-value products. His work is displayed at the National Waterfront Museum (From Bin to Bulb) features a user device, and he is the founder of Trimtabs Ltd.

Alvin is an alumnus of Welsh Crucible and Digital Economy Crucible.

From Bin To Bulb:

Turning Waste Plastics Into Electricity Wires

 

Public display from October 2019 until April 15th 2020

National Waterfront Museum, Swansea

This project started at Swansea University and looks at how to turn waste plastic into other usable materials such as carbon nanotubes, graphene and carbon fibre.

We are developing more efficient ways in which to light and heat our homes. We plan to reduce the energy being lost during transmission by using special carbon nanotube wires. These nanotubes are made from things like thin plastic film, black plastic food packaging and liquid solvents. All of these cannot be recycled in our household rubbish.

To see more details about the science behind this technology watch this video tour of the Dr. Orb research group.

More details and updates can be found here: http://www.esri-swansea.org/en/from-bin-to-bulb.htm

PhD and MSc projects: Nanoengineering solutions for environmental problems (self-funded)

This is a description of self-funded PhD opportunities that are available at Swansea University’s College of Engineering which are based in the Energy Safety Research Institute (ESRI).

The aim of this project is to positively impact the environment both locally and globally. This will be done by taking carbon waste and turning it into carbon nanotubes (CNTs). CNTs can be used to transmit electricity under a wide range of temperatures, they are much lighter so they offer mass savings, and specialized forms are ballistic conductors which can transmit electricity with near zero loss.

Solid waste products such as plastics can be increasingly difficult to recycle, but they can be repurposed to form CNT electrical conductors. Other waste materials such as carbon dioxide is the most relevant greenhouse gas, and it has also been positively shown to be an effective feedstock for the synthesis of CNTs. They can be formed by either using chemical vapour deposition (CVD) or by using electrochemistry, this allows the researcher an opportunity to explore multiple pathways to success while also developing an expanded set of technical skills.

This project has three goals. Firstly, to explore the full range of materials that will have the greatest impact when used as feedstock for nanotube growth. Second, to improve the conversion rate of waste carbons into carbon nanotubes. Third, to integrate the technology into current industrial standards and practices. Industrial partners, collaborators and stakeholders will be sought in order to increase the impact of this research. The successful PhD student will be expect to present their work at relevant conferences and meetings with stakeholders, and to assist in the publication of journal articles.

There are a range of specializations that can be pursued and will be agreed according to the applicant’s abilities and interests. These specializations range from (but are not limited to):

  • chemical recycling of plastics
  • chemical recycling of rubber
  • chemical recycling of composites
  • conversion of microplastics to carbon nanomaterials
  • conversion of carbon dioxide to carbon nanomaterials
  • conversion of greenhouse gasses to carbon nanomaterials
  • electrical characterization of products
  • design and construction of ancillary devices
  • carbon nanotube amplification and cloning
  • formation of ultralong single walled carbon nanotubes
  • determining the impact of nanomaterials on the environment
  • CFD analysis of fluid behaviour in high velocity laminar flow environments

The details of each specialization can be discussed prior to starting.

Black plastic can’t be recycled – but we’ve just found a way to use the carbon in renewable energy

In this article, I describe our latest scientific work in The Conversation so that it is easily understandable by all readership levels.

Since June until November 2019, this has reached over thirteen thousand readers.

Global Media Interest

Carbon Nanotubes from Black Plasti

Since publishing our scientific article on the use of Black Plastics as a feedstock for the synthesis of Carbon Nanotubes, the following press release generated some global media interest. The article was re-written and republished in 44 other sites of both UK and international websites.
