Ⅳ. Results

◆ Step 1

● Development of analysis and measurement method using neutron scattering measurements.
- To study nanoscale materials using neutrons, we have developed measurement and analysis method for nano scale materials: 1) development of structure analysis and measurement methods using SANS and REF 2) development of analysis and measurement methods for dynamics study of nanoscale materials using TAS and TOF. Some of the technological achievements and knowledge were transferred to HANARO facility and other neutron scattering scientists in South Korea to promote neutron scattering research in South Korea.

● Investigation of nanoparticles, bio-membranes, and magnetisms in nanoparticles
- The sub division 1 took part in investigating nanoparticles and bio membranes using SANS and REF. As a result, we have achieved mainly 1) water re-dispersible single wall carbon nanotubes (p-SWNT) 2) alignment method for the discotic liquid crystals both in bulk and on substrates 3) understanding lipid membranes of DPPC/DPPS 4) investigation of single molecule dynamics of bio-mimicking membranes. The sub division 2 used inelastic neutron scattering as a main tool to investigate dynamics of magnetic materials. At the end of the first stage of the project, we have published SCI articles more than 8 which is the number of articles we have promised in the beginning.

● Neutron scattering workshop
- Four workshops on elastic neutron scattering and two workshops on inelastic neutron scattering have been held including over 70 oral presentations.

● Lectures on SANS/REF
- We have held two lectures on SANS and REF during the project year as well as two lectures on inelastic neutron scattering.

◆ Step 2

● Development of analysis and measurement method using neutron scattering measurement
- To study nanoscale materials using neutrons, we have developed measurement and analysis method for nano scale materials: 1) development of structure analysis and measurement methods using SANS and REF 2) development of analysis and measurement methods for dynamics study of nanoscale materials using TAS and TOF. Some of the technological achievements and knowledge were transferred to HANARO facility and other neutron scattering scientists in South Korea to promote neutron scattering research in South Korea.

● Investigation of nanoparticles, bio-membranes, and magnetisms in nanoparticles
- The sub division 1 took part in investigating nanoparticles and bio membranes using SANS and REF. As a result, we have achieved mainly 1) fabrication of functional nanoparticle (re-dispersible single wall carbon nanotubes: p-SWNT) 2) alignment method for the discotic liquid crystals on substrates 3) understanding of interaction between functional nanoparticles and soft nanointerfaces 4) understanding the interaction between lipid membranes and peptides 5) investigation of cell-penetrating mechanism and drug delivery mechanism. The sub division 2 used inelastic neutron scattering as a main tool to investigate dynamics of magnetic materials. At the end of the first stage of the project, we have published SCI articles more than 12 which is the number of articles we have promised in the beginning.

● Neutron scattering workshop
- Three workshops on elastic neutron scattering and one workshops on inelastic neutron scattering have been held including over 90 oral presentations.

● Lectures on SANS/REF
- We have held one lectures on SANS and REF during the project year as well as one lectures on inelastic neutron scattering.

◆ Step 3

● Development of combined analysis methods of structure and dynamics of nano-scale materials using neutron scattering
- To study nano-scale materials using neutrons, we have developed measurement and analysis method for nano-scale materials: 1) development of combined analysis methods of SANS and neutron spin echo, 2) development of combined analysis methods of nano-structural analysis and time resolved measurement using REF. Some of the technological achievements and knowledge were transferred to HANARO facility and other neutron scattering scientists in South Korea to promote neutron scattering research in South Korea.

● Development of nano-structure manipulation technology using interactions between functional nano-particles and soft nano-interface
- The sub-division 1 took part in investigating interaction between functional nanoparticle and soft nano-interfaces using SANS, REF and neutron spin echo. As a result, we have achieved mainly 1) investigation of interaction between functional nanoparticles and soft nano-interfacial materials with various phases, 2) fabrication of superstructures including nanoparticles and soft nano-materials, 3) understanding about the self-assembly of discotic liquid crystals in thin-film and solution, 4) understanding structure and dynamics of lipid membranes and peptides. The sub division 2 used inelastic neutron scattering as a main tool to investigate 1) control of interlayer exchange coupling in GaMnAs magnetic semiconductor multilayer nanostructures, 2) relations of magnetic order/dynamics in Fe-based multiferroics, 3) air/electrolyte interface characteristics utilizing MG adhesion, 4) penetration of lipid membranes by magnetic nanoparticles, 5) fusion mechanism & structure/dynamics of MPR lipid membranes, 6) structure/dynamics of Malachite Green lipid bio interface adhesion. At the end of the first stage of the project, we have published 15 (14 published, 1 accepted) SCI articleson excellent international journals(J. Am. Chem. Soc., Phys. Rev. Lett, etc.)

● Neutron scattering workshop
- Two workshops on elastic neutron scattering and one international meeting on neutron science have been held including over 50 oral presentations.
