3D-Printed Sculptural Artefact
The 3D-printed sculptural artefact entered by a group of third-years from the UFS.

A group of third-year students from the UFS Department of Architecture exhibited their work at the 2023 Venice Biennale, an international architecture exhibition showcasing ground-breaking architectural work from various countries around the world.

The contributions of world-class architects, researchers, and institutions in architecture are exhibited at this exhibition. “To be featured in this exhibition means that we are recognised by the international community as one of the leading architectural learning sites in South Africa and the work being produced at the institution deserves international acclaim,” says Phadi Mabe, Lecturer in the department.

The students representing the university with Mabe and participating in this event are Anya Strydom, Yamkelwa Simelane, Jan Truter, and Khalipha Radebe.

Mabe says the artefact produced from this project is a 3D-printed sculptural device that shows the translation between sound and object and illustrates the sound data through 3D-printed forms. “The sound structures of South Africa’s languages are mapped three-dimensionally to create a visual and spatial record of language. This unique artefact demonstrates that there are uncharted terrains in architecture, suggesting alternative dimensions that can be extrapolated to show that architecture can represent the intangible” he explains.

The UFS artefact was one of six design artefacts selected for the 18th International Architecture Exhibition – La Biennale di Venezia, which opened to the public in May and closes on 26 November 2023.

Hosted by the Department of Sport, Arts and Culture, the competition involved an emphasis on students incorporating African traditional architecture into their design models.

In future, stargazers and astronomers will look at the Scorpius constellation near the Milky Way with new eyes. Earlier this year, a group of international astronomers announced the discovery of an exotic binary star system, AR Scorpii. The system is in the Scorpius constellation.

Prof Pieter Meintjes, researcher in the Department of Physics at the University of the Free State (UFS), worked with four colleagues on what he describes as a “wonderful discovery”. This sensational discovery, which could lead to the production of cleaner energy on Earth, will be published in the research journal, Nature, early in 2017.

Model developed to interpret new set of measurements
The exotic binary star which was discovered consists of a red dwarf and a white dwarf revolving around each other every 3,5 hours. The binary system showed very prominent pulsations of 117 and 118 seconds respectively. The pulsations can be explained by a bundle radiation produced by the white dwarf star.

“These new observations have shown that the radiation is strongly polarised, a sign that we are dealing with synchrotron radiation here. Synchrotron radiation is produced by electrons accelerated to extremely high energy levels in the magnetic field of the white dwarf star,” says Prof Meintjes.

He developed a theoretical model to interpret a new set of measurements that was taken by the 1,9 m telescope and the 10 m SALT telescope at the South African Astronomical Observatory (SAA0).

Totally unique phenomenon could contribute to energy production on Earth
“I further indicated that the interaction between the magnetic fields of the white dwarf star and the red dwarf star induces secondary processes that specifically describe the behaviour of the radiation in the radio band and infrared band accurately. AR Sco is the first white-red dwarf binary system of which all the pulsated radiation could be explained by the synchrotron process, which is totally unique,” says Prof Meintjes.

According to Prof Meintjes, the value of the model lies in the fact that the processes which produce the radiation in AR Sco, can also be applied to produce energy on Earth.

 

Plasma reactors are based on roughly the same processes which apply in AR Sco, and with refining, it could be utilised to generate electricity in future. This will be much cleaner than nuclear energy.

 

The model developed by Prof Meintjes explains all the radiation in the system – from radio waves to X-rays – in terms of electrons accelerated to extremely high energy levels by electric fields in the system, which then produce synchrotron radiation over a very wide band of the electromagnetic spectrum.

Prof Meintjes is currently working on a follow-up article examining the evolution of the AR Sco, in other words, the origin of such a unique system and the final state towards which it is evolving. “My vision for the immediate future is therefore to develop a model for the evolution of the source concerned,” he says.
