Reference excerpt

Maria Quintana (Lima,1967) was born in Peru. She studied Chemical Engineering at the National University of Engineering. She obtained a master's degree in Chemistry and Chemical Engineering, followed by a PhD in Chemistry with a specialisation in nanomaterials for photovoltaic applications, and conducted postdoctoral research at the Royal Institute of Technology, focusing on solid-state solar cells. At present, Maria is actively involved in projects related to the fabrication of nanoparticles, employing different techniques for their application in various types of devices. In 2019, she received an award for her efforts towards the Organisation for Economic Co-operation and Development (OECD), and was invited to share her story as a woman in engineering in the book called Matilda, a new chapter of women in Engineering in Latin America.

Scientific contributions

Enhancing biogas production using iron nanocomposites The proposal to improve biogas in Peru emerged because the lack of proper treatment of organic waste. It is a renewable gas produced from the decomposition of organic waste generated by industries such as food industry, agriculture and livestock. A team of researchers, Dr Maria Esther Quintana Cáceda, Karenina Macazana, Rosa Flores, and William Gómez, has successfully enhanced biogas production through the addition of iron oxide nanoparticles. This innovation promotes a circular economy by ensuring the efficient reuse of organic waste.

Chemical synthesis of graphene Maria Quintana and Ana Champi aimed to synthesise graphene through chemical methods for its application in dye-sensitised solar cells. Graphene functions as an efficient electrical and thermal conductor, possesses superior strength compared to steel.

Ayrampo: Natural dyes for solar cells

In the search for an effective dye to enhance the light and heat sensitivity of solar cells, researchers discovered that airampo (a cactus used in textil and food) could be used to produce a natural dye. Although they had previously tested chicha morada (a traditional Peruvian drink made from purple corn) and sangre de grado (also known as dragon's blood), but ayrampo exhibited the highest electrical performance.

Treatment of wastewater contaminated with dyes from the textile industry Students from Cayetano Heredia University, together with Dr. Maria Quintana and Dr. Pierre Ramos, proposed the use of the Photo-Fenton process in their Environmental Chemistry and Physics course for the treatment of wastewater contaminated with azo dyes. The proposal arose by the recognition that, according to the United Nations, the textile industry is the second most polluting sector and it is responsible for 20% of freshwater contamination in the country. This dye is the most toxic among synthetic dyes, and by applying the Photo-Fenton process, the dye was effectively degraded it. Furthermore, the study confirmed that this process is a viable option due to its low cost in Peru.

Awards and recognitions

Reintegration Scholarship In 2011, Peruvian National Council for Science, Technology and Technological Innovation (CONCYTEC), National Fund for Scientific, Technological and Technological Innovation Development (FONDECYT) and National System of Science, Technology and Technological Innovation (SINACYT) awarded Dr Maria Quintana in recognition for her research titled "Production of Silver Nanoparticles, Zinc Oxide, and Iron Oxide for Water Purification".

2019 Award Gala – Special Distinction In 2019, María Quintana received recognition for her environmental initiative titled "No More Lead: Decontaminating Buoys for Agricultural-Influenced Lakes to Remove Lead Contamination". The project aimed to address the issue of lead pollution in freshwater ecosystems impacted by agricultural runoff. Quintana's work led to the development of a prototype system consisting of interconnected decontaminating buoys designed to extract heavy metals from contaminated lakes. Following successful results during the initial study phase, her contribution was acknowledged for its potential impact on sustainable water resource management and environmental remediation.

Collaboration in the book: Matilda, a new chapter of women in Engineering in Latin America In 2019, The Federal Council of Deans of Engineering of the Argentine Republic (CONFEDI) and Latin American and Caribbean Consortium of Engineering Institutions (LACCEI) had their first project, resulting in the publication of a book designed to show the role of women in engineering and inspiring young Latin Americans to pursue a career in science. As part of this initiative, Maria Quintana was selected to share her life in the book.

Worked examples

Example 1 — a first encounter with María Quintana (scientist)

Start with the simplest possible case. Write down what María Quintana (scientist) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to María Quintana (scientist) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about María Quintana (scientist) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of María Quintana (scientist)

In research: María Quintana (scientist) appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses María Quintana (scientist) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: María Quintana (scientist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1967 births, Living people, Peruvian academics, so understanding it makes those chapters shorter.
In everyday life: Look for María Quintana (scientist) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
