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.”

State of our campuses: UFS closes campuses until Friday 28 October 2016 to readjust academic programme

2016-10-15

UFS announces strategy for completion of the 2016 academic year

Agreement between UFS management and student leadership in relation to residences

After almost four weeks of student protests about fees at the University of the Free State (UFS) and the subsequent suspension of the academic programme and closing of campuses, the senior leadership announced on 14 October 2016 a strategy to ensure that students will be able to complete the 2016 academic year.

The university on 13 October 2016 announced that it will shut down its Bloemfontein and South Campuses until 28 October 2016 for crucial and complex arrangements to be put in place to readjust the academic calendar and ensure that all students can complete their studies. The senior leadership did, however, make it clear that the university will not be shutting down for the remainder of 2016.

No teaching and learning activities at undergraduate and honours level will be offered between 17 October and 28 October 2016. The university will re-start teaching and learning at undergraduate and honours level in the first week of November 2016.

However, teaching and learning will not take place in the classrooms during November 2016, but through a different mode of delivery that consists of a combination of printed and recorded lectures, study materials and learning aids that will be provided by the university and delivered through Blackboard. In this manner no attempts at disrupting the rest of the academic year will affect our students’ academic programme. Students, however, will sit for the exam on campus.

Students in residence accommodation can return to campus as from 29 October 2016 and it is recommended that students who do not have off-campus internet access return to campus in order to access study material to complete the academic year.A new timetable for exams is still being developed and will be communicated as soon as the arrangements have been finalised.

Faculties have been differently affected by the loss of teaching time. Some faculties like the Faculty of Law have completed their curriculum, while other faculties like the Faculty of Natural and Agricultural Sciences require more teaching time. Some faculties, like the Faculty of Health Sciences, cannot do teaching through alternative modes of delivery.

The needs of the different faculties have been taken into account for developing a rescue plan to complete the 2016 academic year.

The Faculty of Health Sciences will continue its classes and clinical rotations as normal for all three schools on the Bloemfontein Campus and in the relevant hospitals. All students registered in programmes in the Faculty of Health Sciences will stay in residences for the full period of their studies and exams. Final-year medical students will graduate in December 2016 as expected.
In the Faculty of Economic and Management Sciences, final-year students for the Certificate in the Theory of Accounting (CTA) will stay on campus during October through to December 2016 and their classes and tests will not change.
Arrangements for all other faculties and programmes are being prepared and within the next week, students and parents/guardians will receive communication about how curriculum content will be completed and when the final exams will take place.
The university is extending the academic year so that we can recuperate all the lost teaching and learning time. The qualifications conferred on the 2016 class will be of the same quality and standards as all UFS qualifications.

The UFS is and will remain a fundamentally contact teaching and learning education university. However, under the current circumstances faced not only by the UFS, but higher-education institutions across the country, the best way of ensuring the integrity of the academic programmes in most faculties is by using an alternative way of teaching and learning. Other South African universities have chosen the same approach to be able to complete the academic year.

Instead of students going to class, they will have content delivered to them where they are (library, computer labs, their own computers, etc.) through Blackboard and printed and electronic material. This is a different way of learning but students will be carefully guided and supported.

Faculties are currently preparing all the necessary materials and instructions to support student learning.Standards and quality will be the same as if students were attending classes. Some faculties require practical laboratory work as part of their curriculum. The exam timetable will be adapted for these students to be able to complete their practical work when the academic activities commences in November 2016. The relevant faculties will communicate the schedule of practical work directly to the students.

Students in their final year will complete their studies during 2016. It is possible that in some cases the graduation ceremony for these students will be in June 2017 instead of April 2017. This will not prejudice students with bursaries, or committed employment in law firms or other businesses. The university will provide the necessary academic transcripts as proof of the completion of the relevant qualifications. None of these changes will affect postgraduate students.

The university will maintain regular communication with students and parents/guardians to update them on the new exams timetable.Faculties will communicate directly with students about issues related to their programmes.

“One of the areas in which significant progress was made, is that we were able to agree on a basis for stability with student leaders. The student protests occurred during an important time in the university’s academic calendar and the readjustment of our academic programme has put tremendous pressure on academic and support services staff, and created anxieties for parents,” said Prof Nicky Morgan, Acting Rector of the UFS.

“The senior leadership restates its commitment to free education as well as its willingness to stand together with students and other public universities to impress on government the urgency to decide on a time frame for the roll-out of free higher education for the poor and missing middle. We will use the next two weeks to meet with the leadership of Universities South Africa to coordinate collective action in this regard. We will furthermore also roll out a series of activities to inform and educate students and the general public on different models and experiences of providing free higher education,” he said.

The strategy to readjust the 2016 academic year is applicable to students on the Bloemfontein and South Campuses.
