Bayode Adeyanju from Nigeria is developing innovative protective helmets at the Chair of Electronic Devices (ELD) that combine natural and artificial materials.

In February of this year, the scientist arrived at the Chair of Electronic Devices at RWTH Aachen University, having been awarded a scholarship from the German Academic Exchange Service (DAAD). Until May, he will be conducting research under Professor Max Lemme’s supervision, with the objective of developing stable helmets that optimally absorb shocks and offer particularly good protection. For the purposes of his research, Adeyanju is combining artificial Kevlar fibres with natural snail shell nanoparticles. In the context of Nigeria, where snail shells are commonly viewed as a nuisance and a potential environmental concern, their high calcium content renders them of interest for materials research. The scientist crushed both materials and ground them finely. The substance was then combined with epoxy resin, and subsequently filled into a mould, where it underwent a process of hardening. Subsequent tests were then conducted to ascertain the impact resistance, hardness and density of the helmets. The combination of the favourable properties of the two base materials forms the basis for the production of high-performance protective helmets.

In his study, Adeyanju presents the results of his research, which indicates that the combination of natural and artificial materials enables the development of innovative protective materials. At RWTH, the scholarship holder utilises state-of-the-art research facilities and equipment to characterise selected materials. Such studies would not be possible at his home university in Nigeria.

‘Knowledge is power,’ says Adeyanju, adding: ‘RWTH has everything it takes to change the world.’

The first thing he noticed in Aachen was how the streets became quieter in the early evening as people went home, says Bayode Adeyanju. This is very different from his home country of Nigeria, where he is used to having friends and family over. Even though Aachen is quieter in the evenings than Nigeria, Adeyanju felt welcome from the start of his research stay. AMO GmbH, a non-profit research organisation, is also contributing to this by supporting his four-month stay. And after one month at RWTH Aachen, Bayode Adeyanju is sure that he would like to come back and continue his cooperation with the Chair of Electronic Devices (ELD).

‘I have received a great deal of support from my colleagues at the ELD and at AMO, as well as from the students, and I feel very happy here,’ says the scientist.

Adeyanju decided to apply to the DAAD two years ago and was accepted last year. The German Academic Exchange Service is a prominent funding organisation that facilitates international student and academic exchange. Funded by German universities and student bodies, the organisation aims to prepare future specialists and managers to act responsibly and to create lasting connections worldwide. This objective is pursued by fostering professional and cultural networks among scholarship holders. Since its foundation in 1925, the DAAD has sponsored more than 2.9 million young academics in Germany and abroad. It is institutionally supported by the Federal Foreign Office.

With its motto ‘Change by Exchange’, the DAAD emphasises the importance of international understanding and cooperation. Another of the organisation’s central concerns is to support developing countries in establishing efficient universities, thus contributing to social, economic and political development.
