Today we have another interview! 

Luenne Coelho, from Reefaire will tell us all about her journey from architect student to business owner, and how her new plastic waste becomes home furniture. Together we talk about the importance of loving a problem, the need to do the work if we want to see change and why selling an imperfect product is actually better.

Join us to hear about:

• One smart idea to help with the plastic waste problem
• Going from frustration to innovation
• Falling in love with a problem in order to solve it
• The waste in civil construction
• How Reefaire turns plastic cups into amazing decoration
• and Portuguese speakers forgetting words in English (it’s a bottle cap btw)

Check out the books we mentioned:

The Lean Startup by Eric Ries

⁠Escape from Nexus Labs⁠ by Carolina Sofia Carreira

Luenne Coelho is a Brazilian architect and urban planner from the Federal University of Rio de Janeiro (UFRJ), currently pursuing a postgraduate degree in Finance and Controllership at the University of São Paulo (USP). She is the founder of Reefaire, a deeptech startup focused on developing high-performance sheets and composites from plastic waste, with applications in architecture, design, and civil construction. She works at the intersection of materials science, circular design, industrial innovation, and business strategy, focusing on scalable solutions to climate change.

If you want to know more about Reefaire follow their work through their ⁠website⁠ and ⁠LinkedIn page⁠. You can send a message to Luenne through her LinkedIn.

Today we’ll deep dive into properties of electromagnetic waves, focusing on their behavior in different media. We will cover concepts such as refractive index, critical angle and Brewster angle, presenting the Fresnel equations and the Poynting vector to describe wave energy. We will also study wave attenuation in conductive materials, introducing penetration depth and the relationship between wave frequency and material properties.

Don’t forget to follow and share the podcast with anyone that you think might profit from it, so more people can deep dive into materials engineering.

Today we’ll take a deep dive into capacitors and dielectrics. What do you know about Ohm’s law?

All of the materials we’ve been talking about in these last episodes are amazing, but after we’re done with them, what do we do? Let’s explore the different ways we can recycle composites.

This last type of composite is the black sheep of the family. Laminar composites are much different from the ones we’ve been talking about. Have you ever seen a composites without matrix? Let’s deep dive to know more about laminated materials and how to produce them.

Listen to this episode to learn more about the production and applications of polymer composites reinforced with particles. Can you identify some in your house?

Today we’ll move on to Polymeric Fibre Composites (PFC), focusing on their production methods (open mould and closed mould), properties, and applications.

After ceramic composites we’re moving on to metals. Today, we’ll cover composites of metallic matrix and particles as reinforcements. The powder technologies are already familiar if you’ve been listening to the last few episodes, but we bet squeeze casting infiltration and spray co-deposition are new concepts.

Last episode we talked about particle reinforced ceramic composites, but what about if we want create metallic composites?

What can we do with powder technologies? Composits of ceramic matrix and particle reinforcement for example. But powder technology isn’t the only way. Join us to see all the advantages and disadvantages of processes like chemical vapour infiltration and liquid phase infiltration.
