Summary
Dr. Sudhagar is a researcher working for the Department of Materials Engineering at Swansea University in the United Kingdom, whose work is currently focused on the application of quantum dots in the energy, environmental and healthcare sectors.
So, what exactly is a quantum dot? Dr. Sudhagar explains that a quantum dot is an inorganic semiconductor material that ranges from one to 10 nanometers in diameter--which is 14,000 times smaller than the diameter of a human hair. Following quantum mechanical behavior, the quantum dot has many applications, including land harvesting, cancer nanomedicine, and solar energy. For example, placing a quantum dot in water and under sunlight causes the water to split into its component parts of hydrogen and oxygen atoms. In addition, it is significantly cheaper than similar, organic materials, such as organic light-emitting diodes (OLEDs).
Also discussed is one of the challenges presented by the existence of toxic cadmium sulfide in quantum dots. How do we go about garnering the uses of quantum dots while preventing the toxicity of cadmium sulfide? Dr. Sudhagar provides two solutions. Tune in to hear his answers to this question and many more.

| 0:07.0 | Future Technologies is to transform our lives for better or worse or the focus of this podcast. |
| 0:13.0 | Almost here means these technologies are now here and starting to be used. |
| 0:17.0 | Or just around the corner, for Bitcoin to artificial intelligence, |
| 0:21.0 | 3D printing, blockchain, virtual reality, and more. |
| 0:25.0 | Hello, this is Richard Jacobs with the Future Check Podcast. My guest today is Dr. Sudager. We're going to be talking about quantum |
| 0:34.8 | dots and nanomedicine. Dr. Sudager, how you doing? |
| 0:38.0 | Yeah, fantastic, Jacob. Thank you very much for inviting me to share my experience on my discovery to your podcast. |
| 0:45.0 | Thank you very much. |
| 0:47.0 | Well tell me what what are you working on? Let's start with that. |
| 0:50.0 | Oh yeah, actually I'm a sub-chemimruh to Rice Six-Tong fellow and group leader in Swansea University |
| 0:56.2 | the United Kingdom. |
| 0:58.1 | And mainly I'm working on the materials science engineering area. |
| 1:01.7 | So today I'm going to sharing about my recent discovery and my future |
| 1:07.0 | futuristic idea or my plan to you. |
| 1:12.0 | Okay, so material science, so what is your research about? |
| 1:15.0 | Yeah, mainly my research is focus on developing the low-cost |
| 1:20.0 | semiconductor nanopole optical and quantum dots for a multi-functional |
