It is based on the inelastic scattering of light and provides a unique spectrum for the sample under study. The advances in lasers and detectors, their combination with imaging systems and the discovery of new phenomena have expanded the use of this technique in several research fields. In the particular case of biology and life sciences, it has been used to provide chemical and compositional information on plant and animal tissues, cells, biofluids, etc., with the advantage that the presence of water molecules normally does not cause interference in the measured signal.</p>","PeriodicalId":101021,"journal":{"name":"PhotonicsViews","volume":"21 5","pages":"24-27"},"PeriodicalIF":0.0,"publicationDate":"2024-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/phvs.202400039","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142573959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among other things, disruptive technologies are needed to tackle such problems. Additive manufacturing (AM) is regarded as the ‘game changer/paradigm shift’ technology for the digital, automated production of the future — as the key enabler of ‘Production 2.0’. This sustainable and resilient technology enables new paths to innovative solutions across all industries through a high degree of individualization (mass customization) and great design freedom (‘manufacture for design’ instead of ‘design for manufacture‘). For example, internally cooled turbine blades for H<sub>2</sub>-capable gas turbines, lightweight structures for more efficient aircraft or patient-specific implants are only made possible by AM. In this way, AM makes an important contribution to solving the social challenges mentioned above now it is necessary to transfer this technology to board industrial use.</p>","PeriodicalId":101021,"journal":{"name":"PhotonicsViews","volume":"21 5","pages":"39"},"PeriodicalIF":0.0,"publicationDate":"2024-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/phvs.202470517","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142574081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
