It elucidates the critical global challenges stemming from unsustainable resource extraction and the linear «take-make-dispose» approach, including climate change, resource depletion, and biodiversity loss. Circular chemistry emerges as a promising solution, guided by principles of green chemistry and circular economy. It advocates for perpetual material cycles, emphasizing sustainable end-of-life strategies and product design that prioritizes reuse and recycling. We underscore the need for chemistry to prioritize efficiency, safety, and circularity, while also addressing challenges associated with complex waste streams and the responsible mineralization of chemicals. Achieving circular chemistry necessitates cooperation among individuals, educational and scientific institutions, industries, and regulatory bodies, and as such it can significantly contribute to mitigating global environmental crises by establishing sustainable material circulation as a cornerstone principle.","PeriodicalId":375588,"journal":{"name":"Mètode\nRevista de difusió de la investigació","volume":" 66","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141680029","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}

But the sensor biofunctionalization, the way bioreceptors are immobilized on the sensor chip, is still an unresolved challenge that demands for specific research in surface chemistry strategies and the use of novel nanomaterials. We provide a brief overview of the key factors driving the improvement of medical biosensors, with a special focus on the current limitations in sensor surface modification and the direct analysis of human samples. We conclude the successful implementation of cutting-edge diagnostic biosensors will only be possible through the collaborative synergy of different sciences, including physics, biology, engineering, and certainly chemistry.","PeriodicalId":375588,"journal":{"name":"Mètode\nRevista de difusió de la investigació","volume":" 29","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141677922","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}

On the other hand, primary extraction poses increasing environmental problems due to the progressive decline in the mineral concentration of deposits (ore grade). In this context, electronic waste is becoming a very promising source of secondary copper. However, this form of copper recovery presents a number of technological and chemical challenges, including the use of renewable energy, the separation of plastics from waste and increasing process efficiency. Given the thermodynamic limitations of these processes, other non-technological aspects are very important in the transition.","PeriodicalId":375588,"journal":{"name":"Mètode\nRevista de difusió de la investigació","volume":" 36","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141679751","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}

The application of this catalytic system laid the foundations for the development of industrial agriculture and led to an unprecedented acceleration in the growth of human societies during the so-called Green Revolution. However, this production model does not appear to be able to adapt to the current challenges of energy sustainability and climate crisis response. The Haber-Bosch cycle has a major impact on energy consumption and carbon dioxide emissions. In order to rethink this agri-food model, this article examines chemical and technological development strategies to move towards an energy and environmentally sustainable model.","PeriodicalId":375588,"journal":{"name":"Mètode\nRevista de difusió de la investigació","volume":" 28","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141678757","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}

Everything we are and do is in some way chemistry. In the Age of Enlightenment, with the lucid impetus of Antoine Lavoisier and his wife Marie Anne Paulze, this ancient knowledge became a scientific discipline. Like a spark falling on a powder keg, it would ignite the great social transformations of the 20th century. New industries emerged that filled our lives with colourful materials, plastics, with almost infinite uses; developed new generations of medicines that killed off endemic diseases; and provided agricultural inputs – fertilisers and pesticides – that boosted food production on an unprecedented scale. Chemistry has undoubtedly improved our quality of life, but it has sometimes been misused, overshadowing the important role it has played and continues to play in the development of a world that must necessarily become more sustainable.","PeriodicalId":375588,"journal":{"name":"Mètode\nRevista de difusió de la investigació","volume":" 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141680214","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}

Analysing periodic variations in the brightness of certain stars (Cepheids) by using photographs, Hubble was able to show that the distance between Andromeda and the Earth was much greater than previously thought. Thus, Andromeda, previously thought to be a nebula, had to be a galaxy different from our own. Suddenly, the estimated size of the universe went from a few hundred thousand light years to a few billion light years.

Great botanists such as Pius Font i Quer greatly valued her unique way of capturing nature. As a woman and an artist who was passionate about nature and who was also scientifically very curious, her representation of plants was different from the typical work of the time. Her innovations are interpreted as an alternative artistic discourse to the dominant patriarchal dialogue and a manifestation of the female touch. Access to unpublished documents – Davit's correspondence with a friend – has made it possible to reconstruct some of the key aspects of her work, involving the crossroads between the aesthetic exaltation of flowers and a gender perspective.","PeriodicalId":375588,"journal":{"name":"Mètode\nRevista de difusió de la investigació","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129632698","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}
