Dr. Alvin Orbaek White is a Senior Lecturer and Sêr Cymru II Fellow and at the Energy Safety Research Institute (ESRI). His vision is to advance global energy sustainability by developing more efficient and equitable methods of transmitting electricity. He is building a research group that develops new methods to produce and use carbon nanomaterials. While also building a community of researchers and stakeholders to engage this issue. He aims to impact the environment both locally and globally positively. This will be done in a two-fold manner. Firstly, by taking carbon waste and turning it into carbon nanotubes (CNTs). Secondly, to use CNTs to transmit electricity because they are much lighter so they offer mass savings and specific forms (ballistic conductors) transmit electricity with near-zero loss. Alvin also has active research interests into Blockchain technologies and innovation, as well pursuing impact activities to communicate the socio-technical aspects of science and technology better.

Throughout his academic career, Dr. Orbaek White has worked to develop innovative methods to synthesise and characterise carbon nanomaterials. He completed his PhD at Rice University, USA, on the catalytic growth of single-walled carbon nanotubes. At the Massachusetts Institute of Technology (MIT), he developed a novel technique resulting in the growth of SWCNTs with centimetre length scales; called ultra-long CNTs. Alvin's research activities are now heavily focused on using circular economy philosophy to close the loop on the carbon cycle.

Alvin is an alumnus of the Welsh Crucible (2017) and the Digital Economy Crucible (2017).

Teaching

  • EG-103 Heat Transfer

    The module is designed to provide a basic understanding of heat transfer in Chemical Engineering. Subjects will include: conduction, convection (forced and natural) and radiation. Students will be given a basis for the more advanced study of the subject in other modules. Students will be introduced to process equipment used in industry that deals with heat transfer.

  • EGSM05 Engineering Technology, Innovation and Application

    This module will give students an overview of the role of engineering technology and innovation in society. By understanding the process of technological development, transfer, implementation and commercialisation for different economic and political settings, students will be able to critically evaluate and assess where and how technology could have a positive impact in the context given. Students will develop design concepts in response to a problem defined by industry, utilising appropriate engineering analysis methods and critically evaluate the success of the concept being developed. Students will also consider how technology could be effectively transferred to be managed by stakeholders and commercialisation in long-term strategic development.

  • EGSM33 Appropriate Technologies (ELM Pathway)

    This module will give students an overview of the role of technology in society. By understanding the process of technological development, transfer, implementation and commercialisation for different economic and political settings, students will be able to critically evaluate and assess where and how technology could have a positive impact in the context given. Students will also consider how technology could be effectively transferred to be managed by stakeholders and commercialisation in long-term strategic development.

Applying nanotechnology to solve environmental problems

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.
