0:09The ACE-T1 Experiment means that advanced colloidal experiment. It means that we are performing the new science with a colloid particle. The colloid particles want to make us a new structure in a three-dimensional space. They will provide a new science because there is no information about the real interaction between the two particles. Experiment design was obtained from our previous research. The colloidal particles such as the Janus particle on Earth make us a 2D structure. However, we cannot create a three-dimensional structure because of sedimentation impact of gravity. If we perfectly remove the masking factor of gravity, If we can make some new structure such as a three-dimensional structure, if you succeed in those kinds of science, we can obtain the new principle or new science.
1:15In some cases, we are increasing the strength of hydrophobic interaction, in some cases we are increasing hydrogen bonding, in other cases we're increasing the electrostatic force. There will be some ensemble force so we can make us a new three-dimensional superstructure and then based on these kinds of principle we can direct the assembly, we can induce the directed assembly of phenomena. Those kinds of directed assembly provide a new design tool from the tiny molecule. Based on these kinds of information, we can make a new three-dimensional infrastructure to apply it to commercial sites such as a photonic crystal. They will make us some new tunnel. That tunnel will be an alternative way to communicate with something and we can replace the conventional semiconductor memory.
2:14And the other side is that we can create an intelligent delivery system. The hot issue is how can we deliver the specific drug to a specific target. They will make some three-dimensional structures, they protect some immune cell or some other enzyme attack. Those kinds of systems specifically delivered to specific tissue or specific cell after that they will reassemble it, they release the drug. If we apply this kind of treatment structure onto the skin, we can make some deep delivery of cosmetic compound into the specific cell or specific tissue. So that's some new advance in cosmetic industry. The most important thing is collaboration between two countries, USA government and Korean government.
3:17Basically, this work was supported by the U.S.A. government and especially NASA at the Grand Research Center. They will provide a great chance to perform the new science and engineering for me. The next step we want to also collaborate with the NASA Grand Research and Colloidal Engineering team. I would like to quote some Armstrong saying That will be a small step for us. However, that's going to be a big leap for Korean society. Thank you for your collaboration. I really appreciate your devotion to our group.
