PhD student Emmie Chiyindiko runner-up at international science summit

With her talk on ‘Breaking the walls of darkness’, Emmie Chiyindiko came in second out of the 74 pitches presented at the recent Falling Walls Science Summit.

“I need you to take a moment and imagine trying to do everything that you do every day … without reliable energy. Or I’ll ask you this … How far would you walk to charge your phone if you didn’t have electricity? Would you walk for hours? Kilometres?”

“Well, that’s what millions of people in sub-Saharan Africa do daily to charge their phones. One billion people globally don’t have access to electricity in their homes and in sub-Saharan Africa, more than half of the population remains in the dark.”

This was the introduction to Emmie Chiyindiko’s talk at the recent Falling Walls Science Summit earlier this month. Emmie, who is a PhD student in Chemistry at the University of the Free State (UFS), came in second out of the 74 pitches presented with her talk on ‘Breaking the walls of darkness’ in the ‘Breakthrough of the year in the emerging talents category’.

Falling Walls Lab is a world-class pitching competition, networking forum, and steppingstone that brings together a diverse and interdisciplinary pool of students, researchers, and early-career professionals by providing a stage for breakthrough ideas, both globally and locally.

Emmie, who sees getting out of bed every morning as just another opportunity to “be the exceptional young black female scientist that I am”, won the local Falling Walls Lab in Cape Town in October, which resulted in her going through to the finals in Berlin. She plans to host the Falling Walls Lab in Zimbabwe, her homeland, next year.

This innovator and science communicator, whose work has been covered in Forbes Science, News24, and the Sunday Times, among others, refers to her obtaining second place on the international stage for her research as “a tremendous achievement and a new height in my science communication career. That level of recognition from the world leaders in science, technology, and science engagement cannot be overstated”.

Ending energy poverty

She believes Sustainable Development Goal 7 – leaving no one behind and eradicating global poverty – must be preceded by intentional efforts to end energy poverty. “My research on dye-sensitised solar cells (DSSC) with special metal complexes is among the most interesting alternatives to conventional solar cells.”

Emmie explains: “The design of the cells is inspired by photosynthesis – that good old process plants use to transform sunlight into energy via chlorophyll. Instead of a leaf, the cells start with a porous, transparent film of eco-friendly titanium dioxide nanoparticles. The film is also coated with a range of different dyes that absorb scattered sunlight and fluorescent light. When sunlight hits, it excites the electrons in the dye, creating an endless supply of energy.

The bright side of this research is that there are several benefits to this invention. It produces energy that is cheap, reliable, and relatively simple and inexpensive to produce. Emmie adds: “These next-generation cells also work impeccably in low-light and non-direct sunlight conditions, providing all-year-round energy with no disruptions. DSSC is also three times cheaper than conventional cells and produces 40% more energy.”

Improving livelihoods

She continues: “It does not degrade in sunlight over time as do other thin-film cells, making the cells last longer, and requiring less frequent replacement. DSSCs are also mechanically strong, because they are made of lightweight materials and do not require special protection from rain or abrasive objects.”

Emmie has proven that solutions to our current energy situation are available. “We are on the cusp of an energy revolution, and we must act now. Solutions are available, and if we do not seize them during a time of crisis, when will we?”

She believes that creating technology like this can end the energy crisis and improve livelihoods. “Billions of people simply lack enough energy to build a better life. Affordable, abundant, and reliable energy can go a long way to store food, power life-saving medical equipment, and run trains and factories. It can help communities to grow and prosper and to access opportunity and dignity. Societies where people have access to energy have lower childhood mortality, a higher life expectancy, they eat better and drink cleaner water, and have a better literacy rate.”

Kovsie artists to rock at Vryfees

2014-06-18

It is the dead of winter in the heart of the Free State. The Vryfees is laying full steam ahead.

However, the talent that makes of this annual arts festival such a phenomenal success doesn’t only come from outside of our Bloemfontein Campus. This year’s productions will abound with performances by Kovsie staff, students and alumni from our Department of Drama and Theatre Arts.

Behind the scenes, our people will also play a vital role in the achievement and progress of the festival. Prof Luwes is a member of the festival committee and together with Dr Venter and Godfrey Manenye, he also serves on the artistic selection committee for theatre.

Thys Heydenrych, lecturer in the above department, was appointed as the technical manager of this year’s Vryfees. This means that he is in charge of the placement and assigning of venues for productions on campus. All the technical aspects for these venues rest on Heydenrych’s shoulders. For this huge task, he is supported by a team of technical staff which includes mostly students.

Take a look at the list of all our Kovsie artists who are working hard to make the 2014 Vryfees better than ever:
