In order to fully utilize an enhanced electro-magnetic field generated by LSPR, the spatial arrangement of dye molecules near noble metal nanoparticle plays an important role. In this study, donor and acceptor molecules are sequentially introduced on the plasmonic nanoparticles and investigated the correlation between the spatial arrangement of dye molecules and the UC enhancement behavior in solid-state TTA-UC.. |

This enhanced electromagnetic field, so-called a hot spot, amplifies the optical absorption and emission of dye molecules in nanogaps. In this study, we fabricated large-area plasmonic Au nanogap arrays with highly integrated hotspots by utilizing the spontaneous nanophase separation of block copolymers. These arrays showed the amplification of upconversion emission based on solid-state triplet-triplet annihilation (TTA-UC).. |

| 6. | Shigenori FUJIKAWA, Development of Global CO2 Recycling Technology towards “Beyond-Zero” Emission, Innovation for Cool Earth Forum, 2022.10, Direct CO2 capture from the air (direct air capture, DAC) is one of negative emission technologies that are expected to keep global warming below 1.5 °C. CO2 capture by permselective membranes is advantageous because of its smaller and simpler set-up. We have developed highly CO2 permeable nanomembrane which could separate diluted CO2 from N2 stream at the ambient condition. CO2 capture by membrane separation has no restrictions on the point of installation when implemented in society. This ubiquity of CO2 capture is an advantage of membrane separation, given that air can be found anywhere on the earth.. |
| 7. | Shigenori FUJIKAWA, Research and developments of carbon management technologies toward “Beyond-Zero” society., Seul National University- Kyushu University Joint symposium, 2022.09, Climate change caused by emissions of greenhouse gases into the atmosphere is a most important issue for our society. The anthropogenic nature of climate change necessitates development of novel technological solutions in order to reverse the current carbon dioxide (CO2) trajectory. Direct CO2 capture from the air (direct air capture, DAC) is one among a variety of negative emission technologies that are expected to keep global warming below 1.5 °C, as recommended by the Intergovernmental Panel for Climate Change (IPCC). CO2 capture by permselective membranes is advantageous because of its smaller and simpler set-up. We have developed highly CO2 permeable nanomembrane which could separate CO2 from N2 stream with 1000 ppm of CO2 at the ambient condition. In addition, CO2 capture by membrane separation has no restrictions on the point of installation when implemented in society, so CO2 can be captured anywhere by membrane technology. This ubiquity of CO2 capture is an advantage of membrane separation, given that air can be found anywhere on the earth. Here, the potential of membrane separation for DAC is discussed and the perspective of membrane-based DAC and subsequent CO2 conversion technologies being developed in Kyushu University will be described.. |

| 15. | Shigenori FUJIKAWA, Ubiquitous CO2 capture directly from air by nanometer-thick membranes, KTH Climate Action Center Guest lecture, 2021.10, [URL], In order to solve the problem of climate change caused by anthropogenic global warming, carbon dioxide (CO2) that has been emitted into the atmosphere must be captured directly from the atmosphere. This Direct Air Capture (DAC), which directly captures CO 2 from the atmosphere, is one of the negative emission technologies that are expected to keep global warming below 1.5 degrees Celsius. Since the atmosphere exists everywhere on the planet, CO 2 capture from the atmosphere must be achieved anywhere, independent of location. Membrane separation processes have the advantage over chemical solutions in that they are small, simple, and can be installed anywhere. For this purpose, we are developing thinner separation membranes made of highly CO2-permeable polymeric materials and attempting to realize CO 2 capture from the atmosphere by separation membranes. Recently, we have succeeded in developing a defect-free, free-standing CO2 separation nanomembrane that has the highest CO 2 permeability reported so far, with no gas leakage through pinholes, even though it is only about 30 nm thick (about 1/1500 of a hair). The nanomembrane has succeeded in selectively recovering CO 2 from a gas mixture of only 1,000 ppm, which is comparable to the concentration of CO 2 in the atmosphere. The advantage of the extremely efficient separation of CO 2 demonstrated in this study shows the feasibility of direct air capture by membranes, which had not been considered before.. |
| 16. | Shigenori FUJIKAWA, A New Strategy of Negative Carbon Emissions by membranes for Ubiquitous CO2 capture, MIRAI 2.0, 2021.06, Climate change caused by emissions of greenhouse gases into the atmosphere is a most important issue for our society. The anthropogenic nature of climate change necessitates development of novel technological solutions in order to reverse the current CO2 trajectory. Direct capture of the carbon dioxide (CO2) from the air (direct air capture, DAC) is one among a variety of negative emission technologies that are expected to keep global warming below 1.5 °C, as recommended by the Intergovernmental Panel for Climate Change (IPCC). Current DAC technologies are mainly based on sorbent-based systems where CO2 is trapped in the solution or on the surface of the porous solids covered with the compounds with high CO2 affinity. These processes are currently rather expensive, although the cost is expected to go down as the technologies developed and deployed at scale. CO2 capture by permselective membranes is advantageous because of its smaller and simpler set-up. Unfortunately, its efficiency is less than satisfactory for the practical operation of the DAC. Among polymeric membrane materials, rubbery poly(dimethylsiloxane) (PDMS) is known to display high CO2 permeance and ultimate thinning of PDMS membranes is a promising and straight forward way to prepare high CO2 flux membranes. We developed defect-free, free-standing nanomembranes of PDMS, and discuss the effect of the membrane thickness on the gas permeance by using precisely defined nanometer-thick PDMS membranes systematically. Throughout the efforts on ultimate thinning of PDMS membranes, our achieved CO2 permeance reaches almost 40,000 GPU (the highest one ever reported) and reasonable CO2/N2 selectivity at the thickness of 34 nm without a gas leak from pinholes. This value is much higher than those reported by other groups in the past (less than several thousand). Furthermore, the separation is achieved even at a CO2 concentration of 1,000 ppm in N2, which has never been investigated under such ultra-diluted concentration conditions in past reports. The advantages of extremely efficient separation of CO2 found in our result demonstrates the feasibility of direct air capture by a membrane, which has never been considered before.. |
