We interviewed Vanessa to find out more about her area of research and her contribution to the series.

1. Could you briefly explain the focus of your article to the non-specialist (in one or two sentences only) and why it is of current interest?

In this study, we employed chemical techniques to combine three distinct vital groups into a single structure. These cores include naftoquinones, natural products such as Vitamin K; selenium, an essential micronutrient for life; and triazoles, structures present in several drugs.

The aim was to investigate the electrochemical properties of this new and innovative combination. Why? Because delving into the study of such a structure holds the potential to yield sophisticated materials like optical sensors or even more potent medications.

2. How big an impact could your results potentially have? In your opinion, what are the key design considerations for your study?

The initial impact was the development of an efficient synthesis strategy, using a cycloaddition reaction that enabled the obtention of a series of 10 molecules with diverse substituents and high yields. The second noteworthy impact was the investigation of photophysical, electrochemical, and potential generation of reactive oxygen species. Our studies have demonstrated the promise of these structures and highlighted the differences between the chalcogens S, Se, and Te, motivating us to further explore the developed molecules. The insights obtained are crucial for future applications of these derivatives in various biological assays.

3. Could you explain the motivation behind this study?

The driving force behind the research conducted by our group is to promote well-being and enhance life for society, particularly for those facing socio-economic challenges. Leveraging our expertise in synthesis and diverse applications, we aim to develop technologies that will reach the market and benefit these individuals. For instance, this includes the creation of new, more efficient and affordable pharmaceutical options, as well as innovative materials that are cost-effective and adhere to the principles of sustainability. And this study was no exception…

4. Which part of the work towards this paper proved to be most challenging?

The most challenging aspect of any research endeavor, especially for young and woman researchers in Brazil, is conducting high-quality science with limited resources. From a chemical standpoint, the biggest challenge was obtaining the molecules. In other words, we knew that combining these cores held immense potential across various fields, but we needed to develop an efficient strategy to merge them and obtain them in pure form. Thus, making this strategy work was the greatest hurdle we faced.

5. What aspect of your work are you most excited about at the moment?

My work fascinates me on two fronts: firstly, the opportunity to generate knowledge that will add value to society, new medicines, new materials…and secondly, the formation of high-quality human resources every day. Inspiring future generations to seek, through science, ways to aid humanity is fantastic, highlighting the motivation to woman to be scientist. I would like to be an example for them and this motivates me every single day.

6. How has your research evolved from your first article to this particular article?

My first article, as an undergraduate student, delved into the synthesis of organochalcogen-amino acid derivatives for application in asymmetric catalysis. As it is evident, my career trajectory has been dedicated to exploring the potential of organochalcogen compounds combined with other biologically compatible molecules. After completing my PhD studies in this area and falling in love with everything that involves research, I decided that this was the career I wanted to pursue. I was approved in my first competition and since then, I have been developing research in the area of chalcogens. I have already received some awards with recognition from peers and the media. I also emphasize the research lines developed by our group, involving various Nobel Prize-winning discoveries, both in the past and in contemporary times.

7. What is the next step? What work is planned?

The next step for our work, which we are already being done, is the application of these structures in biological assays, both in vitro and in vivo, particularly those involving reactive oxygen species. Additionally, we are optimizing the structure to enhance photophysical and electrochemical properties. All these works have one goal in the end of the day: to save lives and help make people’s lives better.

8. Why did you want to publish in RSC Advances?

I aimed to publish in RSC Advances because it holds a prestigious position within the academic community. The journal features articles of exceptionally high quality that garner significant citations. Moreover, the editorial support, decision-making process time, and bureaucratic procedures are all easily manageable. I would also like to highlight the support provided to us young Brazilian chemists by the Royal Society of Chemistry, which yields incredibly positive outcomes.

9. What are your thoughts on open access publishing?

I believe that open access publishing is the very near future for academic article publications worldwide. I am in favor of it because knowledge should be shared without costs for society, ultimately benefiting all of us. However, as a scientist in a developing country with limited funding, I am deeply concerned about open access because we may not have the means to publish due to the fees charged by journals. Therefore, there needs political actions in place to address this issue as well.

1. Could you briefly explain the focus of your article to the non-specialist (in one or two sentences only) and why it is of current interest?

The focus of our article is to simulate and understand the enhancement in the thickness of the colloidal film produced by unidirectional drying an electrolyte-colloid suspension, under normal and microgravity. This is of current interest in manufacturing microstructured materials for ground-based and in-space applications, such as thermal coatings, electrodes, and photonic crystals.

2. How big an impact could your results potentially have?

Our work demonstrates an order-of magnitude enhancement in the thickness of the colloidal film due to the enhanced colloidal transport by the solute concentration gradient generated during unidirectional drying.

3. Could you explain the motivation behind this study?

The enhanced colloidal transport by a solute concentration gradient, known as diffusiophoresis, has been ignored in prior modeling. Prior to our simulations, we envisioned that diffusiophoresis will be pivotal in the drying process, since the typical velocity of colloidal transport by diffusiophoresis is significantly larger than that by solvent evaporation in a drying cell.

4. In your opinion, what are the key design considerations for your study?

The key design consideration for our study is to employ direct numerical simulations and develop a macrotransport theory to analyze the advective-diffusive transport of an electrolyte-colloid suspension in a unidirectional drying cell under the influence of gravity and diffusiophoresis.

5. Which part of the work towards this paper proved to be most challenging?

The most challenging but enjoyable part of this work is to educate and guide my students to complete this first project of them. We are glad that we made it!

6. What aspect of your work are you most excited about at the moment?

The theme of our research is heterogeneous soft matter transport and design. We are excited about developing predictive multi-scale computational tools and fundamental theory to address emerging National Academy of Engineering Grand Challenges, emphasizing on close collaboration with experimental groups to translate knowledge into applications.

7. How has your research evolved from your first article to this particular article?

I am grateful to my undergraduate, master’s, doctoral, and postdoctoral research mentors, who guided me from my first article in hydrophobic microchannel flows to other published work in complex fluid dynamics, colloid and interface science, electrokinetics, and rheology. This article pertains to electrokinetic flows and is a tribute to my mentors 🙂

8. What is the next step? What work is planned?

Diffusiophoresis, the novel component of our article, is one of the specializations of our research group. We are excited about disseminating more of our discoveries of the fundamentals and applications of diffusiophoresis in the future!

9. Why did you want to publish in RSC Advances?

We published our article in RSC Advances, since our work was partly inspired by a high-quality article published in the same journal.

10. What are your thoughts on open access publishing?

Open access publishing is beneficial to disseminate knowledge, especially to institutes or individuals which cannot afford the traditional subscription model.
