CLIMATE ACTION

Although increasing atmospheric CO2 levels will cause climate changes that pose serious risks to humanity, fossil fuels will evidently continue to be used for decades [1]. Large-scale carbon capture [...]

The detailed mechanisms that lowered the atmospheric CO2 concentrations by approximately 100 ppm during glacial periods remain a crucial open question. It is hypothesized that increased ocean alkalini [...]

コンクリートの劣化の一つであるアルカリシリカ反応（ASR）は，コンクリートの材料間の反応に由来し，致命的な膨張ひび割れを引き起こす。コンクリートごとに使用されるセメント・石・砂やその配調合が異なるため，ASRには画一的な対策が通用しない。そこで，各要因の影響度を把握するための膨張実験と，劣化メカニズム解明に向けた微視的観察を行い，数値的な予測モデルを提案することで，新たなインフラ設計・維持管理手法 [...]

In recent years, the loss of understory vegetation such as dwarf bamboo (Sasa spp.) has become more serious due to overgrazing by Sika deer, which is rapidly increasing in population. Degradation of [...]

The apple fruit borer Spilonota samseong (Tortricidae), a pest of apples, has two closely related species (S. albicana and S. prognathana) that do not feed on apples. They closely resemble each other [...]

Proposal for Water Storage Management to Maximize the Flood Control, Water Utilization, and Power Generation Benefits of Pumped Storage Hydropower in Irrigation Pond

Department of Agro-environmental Sciences, Graduate School of Bioresource and Bioenvironmental Sciences

Irrigation ponds, which number approximately 150,000 nationwide, are facing maintenance challenges due to the aging of farmers who manage them, as well as the need for flood control measures due to th [...]

Improving the chemo-mechanical properties of all-solid-state lithium ion batteries by changing the structure of Li-Si alloy anode

Department of Automotive Science, Graduate School of Integrated Frontier Sciences

To advance the commercialization of all-solid-state lithium-sulfur batteries (ASSLSBs), an important key to achieving carbon neutrality, the improvement of energy density and suppression of degradatio [...]

　 I have been conducting research in the field of architecture on deployable structures. Deployable structure has the advantage that they can keep itself flat and be pre-assembled, therefore they impr [...]
