For mitigating global warming, methanation of atmospheric CO2 has been suggested, thereby the CO2 can be stored as methane as a fuel. Conventionally, this reaction needs high temperature and high pressure conditions with using catalyst. Thus, alternative low temperature processes are desired. Our recent research revealed that the CO2 methanation can be performed without external heating just by ball-milling the hydrogen storage alloy in a CO2 + H2 mixed gas atmosphere. Currently, we are conducting research in search of ne alloy structure which can be eective for the above-mentioned reaction with a help of atom probe tomography analysis.ResearchAreasChemistryKeywords■Hydrogen Energy■Hydrogen storage■CO2 methanation■Atom Probe TomographyRelatedresearchSDGTowards hydrogen society, through CO2 utilizationJunior Associate ProfessorRyota GemmaUndergraduate School of EngineeringDepartment of Materials ScienceIn recent years, research and development of the ductile-ber-reinforced cementitious composites (DFRCC) superior to the existing ber reinforced concretes have been actively conducted. DFRCC is a cementitious composite material reinforced with fibers, and it represents crack dispersing properties under tensile, exural or compressive stress. Using DFRCC instead of concrete will also enhance the durability of RC structures.On the other hand, scrap concrete lump processing is a serious problem in construction industry. In order to improve the above problem, it is necessary to show the new possibility of recycled aggregate which was made from concrete lump. Mainly, Watanabe laboratory conducts the fundamental study on DFRCC which used recycled aggregate (, i.e. Environment-Friendly DFRCC).ResearchAreasEngineeringKeywords■Concrete□Reinforced Concrete■Ductile-Fiber-Reinforced Cementitious Composites□Recycled AggregateRelatedresearchSDGEnvironment-Friendly DFRCCProfessorKen WatanabeUndergraduate School of EngineeringDepartment of Architecture and Building EngineeringThe study seeks to infuse architectural design with the way in which public spaces bring cities and their architecture together, and with how the people active in those public spaces use them. Once it has rendered visible those activities, by way of specic surveys and analysis, it can then turn such data into spatial design. Taking the relationship between architecture, such as of university campuses, and urban spaces, and taking space formation that transcends the architectural building types current to date, the study aims for theoretical constructs that can then be linked in to design.ResearchAreasEngineeringKeywords■Urban public space■Campus planning studiesRelatedresearchSDGStudy on the Translation of People's Activities into SpacesProfessorKatsuya IwasakiUndergraduate School of EngineeringDepartment of Architecture and Building Engineering79
