1. Reaching Circular Economy through Circular Chemistry: The Basis for Sustainable Development
Circular chemistry (CC) is an approach for establishing chemical processes to become truly circular and sustainable. It adopts the principles of circular economy (CE), employing life cycle approaches and systems thinking, which help to understand and address the sustainability issues of chemical processes and products. Within this whole context, it is possib

2. Perfil cientométrico da Quimiometria no Brasil
The interest of researchers in understanding the stage of development of specific areas of knowledge is a way to understand their scientific maturity and their capacity for consolidation. This “popularization” of the knowledge of researchers working in a specific area of knowledge also allows a greater ability to recognize where science is produced and w

3. WILHELM OSTWALD PARA ALÉM DO ANTIATOMISMO
The Baltic German chemist Wilhelm Ostwald (1853-1932) had his scientific prestige eclipsed in the history of chemistry due to his rejection to atomic theory, which suggests the permanence of the whig interpretation on history of chemistry in the narratives about him. In this paper, we intend to present elements on Ostwald’s biography far from his role in t

4. AUTENTICAÇÃO DE ORÉGANO (Origanum vulgare L.) ORGÂNICO UTILIZANDO ESPECTROSCOPIA NIR E QUIMIOMETRIA
In recent years, the consumption of organic foods has considerably increased. The basic difference between organic and non-organic food products is the way in which they are produced and processed, and the authenticity of these products is a current trend in food science and analytical chemistry. In this sense, the objective of this work was to propose an an

5. A HISTÓRIA DA CIÊNCIA COMO “REMÉDIO” NO ENSINO DE QUÍMICA: EPISÓDIO - ESTUDO SOBRE A INVENÇÃO DA TEORIA ATÔMICO-MOLECULAR MODERNA
In recent years, much has been said about the approach of the history of science and science teaching. We know that this approach can be made using historical episodes in science classes. In this sense, this work aims to bring a historical episode to be worked on in general chemistry classes in high school, as well as in general chemistry classes 1 of univer

6. THE FUNDAMENTAL IMPORTANCE OF BASIC SCIENCE: EXAMPLES OF HIGH-IMPACT DISCOVERIES FROM AN INTERNATIONAL CHEMISTRY NETWORK
During the last 150 years or more, society has witnessed many key scientific discoveries and inventions, which have dramatically improved not only our quality of life, but our lifespan. However, the motivation of scientists to provide scientific advances has generally not been the achievement of these goals, but mainly driven by research curiosity. Fundament

7. ESTRATÉGIAS DE ESCRITA PARA ABORDAGEM DA COMUNICAÇÃO PÚBLICA DA CIÊNCIA NA EDUCAÇÃO EM QUÍMICA
Although the impacts of science discoveries are relevant to society, awareness of this intellectual output is still minimal. Much of this communicative failure between researchers and the general public lies in the disclosure, which contributes to the superficiality and misinterpretations of the content served. Strategies need to be found to improve science

8. ARGUMENTAÇÃO EM AULAS DE QUÍMICA: ESTRATÉGIAS DE ENSINO EM DESTAQUE
Research in the area of science teaching has highlighted the importance of using argumentation in the classroom, as well as preparing teachers to undertake and conduct activities of this nature. In order to bring elements that contribute to the progress of discussions about the subject, we investigated implementing and developing two teaching strategies (lud

9. MULHERES CIENTISTAS NA QUÍMICA BRASILEIRA
Brazil’s gender gaps numbers are scarce in the field of chemistry. Thus, the motivation of this work is to perform a data survey considering all levels of the academic career and per Brazilian region. The data collected shows a general trend observed in all scenarios, whereas the higher the career level the lower the number of women inserted. Women dominat

11. METABOLÔMICA DE PLANTAS: MÉTODOS E DESAFIOS
Metabolomics has played a central role in various areas of plant sciences, offering new perspectives for the advancement of agriculture, drug discovery, chemical ecology and taxonomy. Plant metabolomics (identification and quantification) aims to understand the relationship between biological systems and genetic, pathological and or environmental stimuli in
