▶Interview
In the dynamic field of nanoscience, Young-jin Yoon's research revolves around X-ray and neutron scattering, directed molecular self-assembly, nanoparticles synthesis, and their applications in nanodevices. Let us take you through the core aspects of his works.
He focuses on understanding the structures of nanoparticles and amphiphilic molecules and their superlattices in X-ray and neutron scattering. Using small-angle neutron/X-ray scattering techniques, he has explored the complexity of these small entities. Additionally, he has applied the contrast variation method to enhance the accuracy of small-angle neutron scattering measurements.
Directed Molecular Self-Assembly forms one of the significant parts of his research, involving the assembly of liquid crystals, block copolymers, and nanoparticles. He has successfully pioneered the creation of binary nanoparticles superlattices through a self-assembly method, showing the potential for unique structures and functionalities.
Nanoparticles Synthesis is a key area of his contribution, spanning from the burst nucleation process for gold nanoparticles to the hot injection method for CdSe quantum dots and the slow growth method for CdSe/CdS core/shell quantum dots. The successful synthesis of iron, nickel, and cobalt nanoparticles further highlights the diversity of his contributions.
He informed the practical application of these nanomaterials finds its place in Nanodevice Applications, specifically in Plasmonics, Metamaterials, and Sensors. This practical aspect underscores the real-world implications of nanoscience, linking theoretical exploration to tangible technological solutions.
He said his research journey was fueled by a commitment to advancing our understanding of nanoscience. He is exploring the vast landscape of materials science and nanotechnology, with these discoveries shaping both his academic landscape and transformative technologies in our daily lives. He looks forward to sharing more insights in our school newsletter.
