- Nanomateriais
- Nanofabricação
P: Quando você descobriu que sua carreira se concentrava em nanotecnologia?
Akinwande: When I started graduate school, I realized the field was very young and started exploring carbon nanotube materials. I was particularly looking for a nascent topic and after 1year of reading about different emerging frontiers, I decided to focus on CNTs especially for radio-frequency applications because it was an area I had some prior experience.
P: Em quais aplicações atuais de nanotecnologia você está trabalhando?
Akinwande: I am working on several applications including wearable tattoo sensors, flexible electronics, and memory devices for information storage and computing. Our main driver is to explore near-term important applications of nanomaterials such as graphene and related atomic sheets. These aforementioned applications are both very important from a technology point of view and might also be commercializable in a reasonable timeframe compared to some more fundamental applications that might need decades to develop.
P: Qual é a coisa mais gratificante em trabalhar com nanotecnologia?
Akinwande: The field is very vast with ample room for innovation and creativity to bring an idea from concept towards practical applications.
P: Há algum exemplo que você possa fornecer que mostre como algo em que você trabalhou impactou positivamente o mundo?
Akinwande: We wrote the first textbook on carbon nanotubes in 2011 and this book has been translated to other languages and is used in many institutions across the World to teach aspects of nanomaterials and nanotechnology.
P: Em quais áreas você prevê que a futura comercialização da nanotecnologia terá o maior impacto positivo no mundo?
Akinwande: The future is hard to predict. I expect nanotechnology will increasingly impact many aspects of society in due time. We already see commercial examples in energy devices such as batteries, thermal management packages in smart phones, and a variety of sensors including diagnostic testing for health.
P: Qual você acha que foi o maior impacto que a nanotecnologia teve no mundo até agora?
Akinwande: Nanotechnology has given us modern semiconductor technology which has benefited virtually all industries and society across the World. From electronic gadgets to mobile health. This was enabled by developing a variety of techniques to make smaller features and components and integrate them on a semiconductor wafer. A lot of technical breakthroughs and invention went into the science and engineering of making things very small (i.e. nano-size), much smaller than a hair strand. This is an example of how nanotechnology has advanced the predominant semiconductor electronics industry.
P: Na última década, a nanotecnologia saiu do laboratório e está causando um impacto real na sociedade. Você trabalhou em algum esforço que ajudou a comercializar a nanotecnologia e resultou em novos produtos ou processos?
Akinwande: Our earlier research on graphene growth and transfer has become commercial process technology. This research involved growing graphene, which is a single sheet of carbon atoms on a substrate of silicon that is suitable for semiconductor technology. With graphene on silicon, advanced electronics can be made that combines the outstanding properties of both materials to realize electronic gadgets superior to what can be achieved with just one of the materials.
P: Sua formação universitária o ajudou em seu trabalho em nanotecnologia?
Akinwande: Yes, it provided foundational understanding in the physical sciences and engineering. Math classes gave me strong quantitative skills in modeling and analysis that requires skills in calculus and statistics. Physics is good for the necessary understanding of thermodynamics, solid-state materials, and quantum mechanics. And electrical engineering classes are crucial for developing applications based on the unique characteristics of nanomaterials. These applications are what we broadly call nanotechnology.
P: Se você tivesse que fazer tudo de novo, ainda se concentraria em aplicações de nanotecnologia?
Akinwande: Yes. Nanotechnology is a frontier field with a lot of room for innovation and as such, it is a very enjoyable field for discovery research.
P: Se um estudante do ensino médio ou universitário estivesse interessado em nanotecnologia, que conselho você daria a ele para ajudá-lo a se preparar para assumir essas funções?
Akinwande: Pursue innovation and critical thinking. There are many challenges in the world from a technology point including the exponential power consumption of data centers, the need for mobile personalized healthcare, portable filtration for clean water, etc. All these global challenges require innovative ideas and new ways of looking at problems.
