Why do scientists sometimes call microalgae "the green gold"? Well, in addition to biofuels and astronaut food, you could use them to make sunscreen. These tiny algae contain substances that protect them from sunlight, which can also come in handy for humans. Unfortunately, they don't naturally produce enough of those substances. Elke Vereecke researches how to grow microalgae packed with those sunlight-protecting components.

Have you ever seen a timber-frame building? 🏠 You might be wondering how safe such a structure actually is. Well, the truth is that we don't quite know yet. Structural engineer Dries Byloos 👷 tells you why and how he is pushing for safer and taller timber-frame buildings.

Sujith Reddy is working on perovskites, a promising new solar cell technology that captures more sunlight and costs less than conventional solar cells. Sounds great, right! But there's a catch: these perovskite solar cells ironically tend to break down when exposed to ... light. Sujith wants to uncover the mechanisms behind this degradation in order to improve perovskites and to use them on a larger scale.

Imagine that, instead of emitting harmful CO2 into the atmosphere, we could recycle it and use it to power your future laptop or smartphone. That's what Kevin Van Daele is researching. He is developing new catalysts to efficiently convert CO2 into formic acid, a valuable chemical that could one day power your future electronic devices. 

Did you know that the average lifespan of a wind turbine is 20 years? After that, unfortunately, wind turbines end up in landfills as they are built from thermosets, materials that can't be recycled (yet). "It's time to change that", says Marlies Thys. She is looking into making recyclable thermosets by using ... wood waste. 

Do you drink juice in the morning or enjoy a glass of wine to relax after a busy day? Did you know that in order to preserve its flavor and prevent bacterial growth, your favorite beverage has to go through several stages of processing? One is the filtration process, a very expensive production stage. To ensure you can enjoy your favorite drink at a low(er) price, Rishav Phukan is developing next-generation membranes, which will help the industry cut costs and produce in a more eco-friendly way.

Do you think we will be able to stop CO2 emissions by 2050? Because that's what we need to do to fight climate change. Worldwide, an estimated one million researchers are currently working on solutions for climate change. At Hasselt University, Talieh Rajabloo is mapping state-of-the-art climate research & technologies that can help energy-intensive industries such as the petrochemical and metal sectors reduce their CO2 emissions.

Plants capture CO2 and, through photosynthesis, convert it into green leaves. Over the past 30 years, the increase in CO2 in the atmosphere has thus led to a widespread increase in the number of green leaves around the world. But recently, there has been a shift: the increase in the number of green leaves is slowing down even though CO2 levels are still rising. Vaidehi Narsingh (Imec - UAntwerp) explains why she is determined to find out what is happening.

Did you ever enjoy a nicely packed fruit salad with an easy-peel lid? It's a beautiful display of packaging technology: the packaging is strong enough to protect your food, yet at the same time very easy for you to open once you want to dive in. Bram Bamps (UHasselt) explains how he optimizes heat-sealing packaging to keep our food safe and to ensure long shelf life.

What does a nutcracker have to do with tackling climate change? Well, Kristof Bal explains it to you in 150 seconds.

To make the production of plastics and other chemical processes less energy-intensive and waste-producing, Max Bols turns to nature. Enzymes, the catalysts of living cells, hold the key to improve chemical processes, as he explains in this video. 

Products with an eco-label are often more expensive than regular products. Bio-engineer Sven Dierickx is determined to change this: he uses yeast from bumblebee honey to make environmentally friendly ánd low-cost detergent 🐝🍽🧽
