Research competitionClear the way for 'Jugend forscht 2020'!
Under the motto "You can do it!", the 'Jugend forscht' competition is entering a new round: for the 55th time, young people are invited to present their innovative research projects - in the fields of mathematics, computer science, natural sciences and technology.
'Prize of the Federal President for exceptional work' for Jakob Rehberger (17) and Jonas Münz (16):
Titanium bone implants have tiny holes and pores, the sharp edges of which must be removed cleanly before surgical insertion. Many of the deburring processes commonly used in the industry leave behind tiny particles or impurities that can enter the patient's body. Jakob Rehberger and Jonas Münz found a solution to this problem. They developed a machine that removes the sharp edges of bone screws using ultrasound waves. The young researchers tested various solvents, temperatures, irradiation angles and irradiation times and analyzed the deburred screws for residues and germs. The result of their research work is a fully automated, ready-to-use ultrasound machine that delivers cleanly deburred and germ-free implants.
