One important application is in earthquake mitigation. In a 'cloaking' process, seismic metamaterials can shield buildings from seismic waves. Professor Tungyang Chen, Department of Civil Engineering,\u0000 National Cheng Kung University, Taiwan, is working with doctoral student Jun-Hong Lin and former master's student Dian-Kai Guo on research to provide new designs of seismic metamaterials. They are utilising theoretical analyses, numerical modelling – including finite element calculations\u0000 based on the multiphysics simulation software COMSOL – laboratory-scale experiments and full-scale field tests with the goal of attenuating earthquakes and ultimately protecting buildings and saving lives. A focus for Chen and the team is on shear horizontal waves, or Love waves, and\u0000 how they can be attenuated by seismic metamaterials. The researchers developed a transversely isotropic model designed to imitate the Earth's geological conditions and were able to assess how Love waves interacted with different resonators and discovered that resonators can be engineered to\u0000 adjust their frequencies and act as a shield for seismic waves. Chen and the team will extend this line of investigation to include other types of ground motion. The researchers are also developing a tool for seismic cloaking in work that involves designing a material with proper internal\u0000 structures and material compositions.","PeriodicalId":88895,"journal":{"name":"IMPACT magazine","volume":"88 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84330856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is why it is particularly important to find ways to maintain the integrity of structures in this country. This involves advanced experiments and structural\u0000 analysis. Assistant Professor Hiroki Tamai, Structural Analysis Laboratory, Kyushu University, Japan, leads a team working to quantify the effects of salt-induced rebar corrosion and alkali-silica reaction (ASR) degradation on the residual load-bearing capacity of reinforced concrete (RC)\u0000 members and structures. The goal is to use the acquired findings in the development of a method to accurately assess the condition of damaged structures and promptly respond with appropriate actions such as repair and reinforcement. The work involves extensive analytical research, including\u0000 advanced experiment and numerical analysis, as well as quantitative evaluations and non-destructive inspection methods, some of which use Artificial Intelligence-based diagnosis systems. In their latest investigations, the researchers have been studying the quantitative understanding of the\u0000 cracking behavior of concrete deteriorated by internal expansion using X-ray CT and other techniques, and the evaluation of the static and dynamic load-bearing capacity of RC beams with deteriorated damage. This will enable them to accurately identify damage to structural members and structures\u0000 due to deterioration caused by internal expansion, to better understand their residual capacity, and to propose more appropriate repair and reinforcement methods.","PeriodicalId":88895,"journal":{"name":"IMPACT magazine","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82069743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diacylhydrazine can be incorporated into polymers to enhance thermal and chemical stability and may also make them oxidatively degradable, which means they can be easily and safely disposed\u0000 of after use, with no environmental implications. Professor Nobuhiro Kihara, Department of Chemistry, Kanagawa University, Japan, recognised the need for a polymer that has a degradation reaction initiated by artificial stimuli, which led him to study oxidatively degradable polymers. Using\u0000 diacylhydrazine, he and his team have developed a polymer that boasts attractive properties and numerous applications and benefits. The polymer maintains high strength, is weather resistant and resistant to heat, water, acid and sunlight yet is rapidly degradable when it is time to start the\u0000 degradation process. This means that it can be easily and conveniently disposed of after use. It can be used in plastic, adhesive or paint and the composite materials can be separated and recycled or reused after use. The expectation is that oxidative degradation will reduce the load for the\u0000 disposal of plastic and there are further opportunities to explore as there is potential for the use of various oxidant-induced degradation reactions in the design of degradable polymers, as well as artificial stimuli other than oxidation, for example electric current, to promote degradation.\u0000 Kihara and the team have developed an oxidatively degradable epoxy resin that can be used as an adhesive and an oxidatively degradable SAP (superabsorbent polymer).","PeriodicalId":88895,"journal":{"name":"IMPACT magazine","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89783491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
