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.”

Situation on the Bloemfontein Campus, and letter to parents
2016-02-28

Letter to parents from Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS 

 

Statement by Prof Jonathan Jansen, Vice-Chancellor and Rector of the University of the Free State (UFS) about the situation on the Bloemfontein Campus


1.    As all of you know, last night we witnessed a really tragic event at Xerox Shimla Park on the Bloemfontein Campus on the occasion of the Varsity Cup rugby match between NMMU (FNB Madibaz) and UFS (FNB Shimlas).
2.    The game started at 18:30 and about 17 minutes into the match, a group of protestors sitting on the north-eastern side of the stadium decided to invade the pitch and disrupt the game in progress.
3.    After a short while, some of the spectators also invaded the field, chasing and brutally beating those protestors whom they caught.
4.    As a university leadership we condemn in the strongest terms possible the vicious attack on the protestors. Nobody, repeat nobody, has the right to take the law into their own hands. While the protests were illegal and disruptive, it did not harm to the physical well-being of the spectators.
5.    The reaction from the group of spectators, however, not only opened old wounds, it trampled, literally and figuratively, on the dignity and humanity of other human beings. This we condemn in no uncertain terms, and no stone will be left unturned to find those who acted so violently on what should have been a beautiful occasion that also brought families and young children together to enjoy an evening of sport.
6.    I cannot over-emphasise our level of disgust and dismay at the behaviour of the spectators. It is NOT what the University of the Free State (UFS) is about and we are working around the clock to gather evidence on the basis of which we will pursue both charges and, in the case of students, also disciplinary action on campus.
7.    At the same time, the invasion of the pitch is also completely unacceptable and we will seek evidence on the basis of which we will act against those who decided to disrupt an official university event.
8.    Clashes between students occurred afterwards on campus and members of the Public Order Policing had to disperse some of them. The situation was stabilised in the early hours of the morning.
9.    Disruption continued this morning (23 February 2016) when students damaged some university buildings, a statue, and broke windows. Additional reinforcements from the South African Police Service were brought in to stabilise the campus. Additional security has also been deployed.


Broader picture
10.    We are very aware of the national crisis on university campuses and the instability currently underway. While the UFS has been largely peaceful, we have not been spared this turmoil, as last night’s events showed.
11.    We are also conscious of the fact that even as we speak, various political formations are vying for position inside the turmoil in this important election year. In fact, part of the difficulty of resolving competing demands is that they come from different political quarters, and change all the time.
12.    We are therefore learning from reliable sources that the Varsity Cup competition is, in fact, a target of national protests in front of a television audience.
13.    And we are aware of the fact that these protests are not only led by students but also by people from outside who have no association with the university. Just as the violent spectators involved on Monday night also included people from outside the university.

The demands

14.    My team has worked around the clock to try to meet the demands of contract workers demanding to be in-sourced. In fact, this weekend past, senior colleagues sat with worker leaders in the township to try to find ways of meeting their demands. We were hoping that such an agreement would be finalised by Monday afternoon (22 February 2016), but on the same Monday morning workers and students were arrested after moving onto Nelson Mandela Avenue, after which the South African Police Service (SAPS) took over as the matter became a public safety concern outside the hands of the university. Since then, it was difficult to return the workers to settle on a possible agreement.
15.    The fact is that the UFS has been in constant negotiation with contract workers to provide our colleagues with a decent wage and certain benefits. In fact, towards the end of last year we raised the minimum wage from R2 500 to R5 000. We were in fact hoping that the continued negotiations would improve that level of compensation even as we looked at a possible plan for insourcing in the future. We made it clear that if we could insource immediately, we would, but that the financial risk to the university was so great that it threatened the jobs of all our staff. Those negotiations were going well, until recently, when without notice the workers broke away and decided to protest on and around campus.
16.    While these negotiations were going on, the Student Representative Council (SRC) on Monday 22 February 2016 also decided to protest. While the vast majority of our 32 000 students were in classes and determined to get an education, a very small group led by the SRC President decided to protest; some invaded the UFS Sasol Library and the computer centre, and with the President eventually made their way to Xerox Shimla Park on which route they confronted the police, interrupted traffic and in fact injured some of our security staff as well as police officials.
17.    The university is definitely proceeding to collect evidence on these illegal and violent acts and will also act firmly against students involved in these protests.

Summary
18.    The events of Monday night represent a major setback for the transformation process at the UFS. While we have made major progress in recent years—from residence integration to a more inclusive language policy to a core curriculum to very successful ‘leadership for change’ interventions for student leaders—we still have a long way to go.
19.    One violent incident on a rugby field and we again see the long road ahead yet to be travelled. As I have often said before, you cannot deeply transform a century-old university and its community overnight. We acknowledge the progress but also the still long and difficult path ahead. We will not give up.
20.    We have 32 000 students on our campuses; the overwhelming majority of them are decent and committed to building bridges over old divides as we have seen over and over again. So many of our students, black and white, have become close and even intimate friends working hard to make this a better campus and ours a better community and country. Like all of us, they are gutted by what they saw on Monday, but the hundreds of messages I received from parents, students, and alumni this past 20 hours or so said one thing—keep on keeping on. And we will.
