Micropropulsion system that provides robust, efficient option, reduces contamination risks is presented at IEEE Pulsed Power and Plasma Science Conference
Finding inexpensive solutions for propelling CubeSats is one of the most critical components of the rapidly growing industry of commercial launches of satellites the size of a loaf of bread. The small size and relatively low cost have made CubeSats popular choices for commercial launches in recent years.
The first CubeSat was launched in 1999. Since then, more than 1,000 have been launched. The rapid development and application of nanosatellite technology has vastly accelerated mission complexity - sparking interest in robust, low-power and high-specific impulse micropropulsion systems.
Purdue University researchers have created a novel micropropulsion system for nanosatellite applications using a liquid fed pulsed-plasma thruster. It uses a liquid propellant for Lorentz-force pulsed-plasma accelerator and extended lifetime ignition system driven by nanosecond long pulses.
"Our innovation helps address current challenges with CubeSat micropropulsion systems, including short operational lifetimes, contamination risks and economic challenges," said Alexey Shashurin, an assistant professor of aeronautics and astronautics in Purdue's College of Engineering. "Our system is better able to operate reliably for the entire mission and the liquid propellant we use does not create the contamination risks to the subsystems that we see with current options."
The Purdue team's work was presented in June at the 2019 IEEE Pulsed Power and Plasma Science Conference in Orlando, Florida.
Overall popularity of the CubeSats is driven heavily by the great advancement in miniaturization of electronic components and sensors that allows for new kinds of space missions and measurements using a CubeSat.
"We have taken the next step toward developing a robust propulsion system for CubeSats to provide for necessary maneuvering during missions," Shashurin said. "Developing innovative technologies like this is one of my passions."
One of the student researchers who worked on the technology, Adam Patel, was named one of "Tomorrow's Engineering Leaders" by Aviation Week Network and the American Institute of Aeronautics and Astronautics. Patel is a senior in the School of Aeronautics and Astronautics.
Shashurin and his team worked with the Purdue Research Foundation Office of Technology Commercialization to file a provisional patent on the technology. They are looking for partners to continue development.
Their work aligns with Purdue's Giant Leaps celebration of the university's global advancements in space exploration as part of Purdue's 150th anniversary. It is one of the four themes of the yearlong celebration's Ideas Festival, designed to showcase Purdue as an intellectual center solving real-world issues.

In living cells, enzymes drive biochemical metabolic processes enabling reactions to take place efficiently. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. Researchers now identified an enzyme that, when illuminated with blue light, becomes catalytically active and initiates a reaction that was previously unknown in enzymatics. The study was published in "Nature Communications".
Enzymes: they are the central drivers for biochemical metabolic processes in every living cell, enabling reactions to take place efficiently. It is this very...
Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick out even very small tumors from normal tissue. The work is published May 25 in the journal Nature Nanotechnology.

Microelectronics as a key technology enables numerous innovations in the field of intelligent medical technology. The Fraunhofer Institute for Biomedical Engineering IBMT coordinates the BMBF cooperative project "I-call" realizing the first electronic system for ultrasound-based, safe and interference-resistant data transmission between implants in the human body.
When microelectronic systems are used for medical applications, they have to meet high requirements in terms of biocompatibility, reliability, energy...
Thomas Heine, Professor of Theoretical Chemistry at TU Dresden, together with his team, first predicted a topological 2D polymer in 2019. Only one year later, an international team led by Italian researchers was able to synthesize these materials and experimentally prove their topological properties. For the renowned journal Nature Materials, this was the occasion to invite Thomas Heine to a News and Views article, which was published this week. Under the title "Making 2D Topological Polymers a reality" Prof. Heine describes how his theory became a reality.
Ultrathin materials are extremely interesting as building blocks for next generation nano electronic devices, as it is much easier to make circuits and other...
Scientists took a leukocyte as the blueprint and developed a microrobot that has the size, shape and moving capabilities of a white blood cell. Simulating a blood vessel in a laboratory setting, they succeeded in magnetically navigating the ball-shaped microroller through this dynamic and dense environment. The drug-delivery vehicle withstood the simulated blood flow, pushing the developments in targeted drug delivery a step further: inside the body, there is no better access route to all tissues and organs than the circulatory system. A robot that could actually travel through this finely woven web would revolutionize the minimally-invasive treatment of illnesses.
A team of scientists from the Max Planck Institute for Intelligent Systems (MPI-IS) in Stuttgart invented a tiny microrobot that resembles a white blood cell...
