TECHNOLOGY TRENDS

Scientists develop pneumatic propellers that could replace diesel engines in ferry boats

The study in the journal Energy Conversion and Management was "conducted to evaluate the technical and economic feasibility of replacing the conventional diesel engine with a pneumatically propelled one on an existing ferry boat within the context of Finland's maritime transport needs," the scientists write.

The study showed that the pneumatic propulsion, while unconventional, holds promise as a sustainable and energy-efficient alternative to conventional marine engines, particularly for short-distance ferry operations.

Diesel engines are currently the most reliable internal combustion engines in terms of power density control and robustness. However, they require large amounts of diesel fuel to power them. Moreover, they can be fairly noisy, and worse, they are a major source of pollution.

Replacing these engines with pneumatic ones is a cleaner and more effective option as these engines can also be incorporated into the ferry body to store air either within the structure of the boat or on auxiliary tanks, which will enhance buoyancy, said Abdul Hai Alami, the lead author.


Transforming plastic waste into high-quality 3D-printed products

Every year, some 5.6 million metric tons of plastic packaging winds up in household waste in Germany after being used just once. So far, less than a third of it can be recycled. Working in partnership with Hochschule Bremen�City University of Applied Sciences, the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM aims to transform this waste into high-quality 3D-printed products.

Volumes of plastic waste are rising, having approximately tripled across Germany over the past 30 years. Packaging waste in particular is a major contributor to this. Where German households produced 2.1 million metric tons of plastic waste in 1994, the figure had risen to 5.6 million by 2023. That makes it even more important to find ways to recycle these single-use products, most of which are based on crude oil.

"But it is much harder to recycle post-consumer waste than plastic residue left over from industrial production," explains Dr. Silke Eckardt, a professor focusing on sustainable energy systems and resource efficiency at Hochschule Bremen�City University of Applied Sciences (HSB). After all, these materials are not only highly heterogeneous but generally also dirty.

To close the production cycle nevertheless, HSB has teamed up with researchers at Fraunhofer IFAM to recycle even these tough-to-handle plastics from private households and then put them to use in additive manufacturing.


Flying robots unlock new horizons in construction

An international team has explored how in future aerial robots could process construction materials precisely in the air -- an approach with great potential for difficult-to-access locations or work at great heights. The flying robots are not intended to replace existing systems on the ground, but rather to complement them in a targeted manner for repairs or in disaster areas, for instance

Robotic arms and 3D printing gantries can already be found on construction sites -- albeit mostly as heavy, permanently installed systems on the ground. They quickly reach their limits on rough terrain or at great heights. A team led by researchers from the Laboratory of Sustainability Robotics at Empa and EPFL has therefore investigated how aerial robots could be used as autonomous construction platforms in the future. In the cover story of the current issue of Science Robotics, the researchers show the state of the art and the potential of this upcoming technology. The advantage is obvious: Construction drones can reach places that are inaccessible to conventional machines, be it in the mountains, on rooftops, in disaster areas or even on distant planets. They also do not require a fixed construction site, can be deployed in swarms, and therefore offer a high degree of flexibility and ease of scalability. At the same time, they could shorten transportation routes, reduce material consumption and make construction sites safer.

Aerial robots are particularly suitable for disaster relief operations -- for example, in flooded or destroyed regions where conventional vehicles can no longer get through. Aerial robots could transport building materials and autonomously erect emergency shelters. Their use is also promising for repairs in places that are difficult to access. They could autonomously detect and repair cracks on high-rise facades or bridges without scaffolding. "Existing robotic systems on the ground often weigh several tons, take a long time to set up and have a limited working radius," explains Yusuf Furkan Kaya, the lead author of the study, from the Sustainability Robotics Laboratory at Empa and EPFL. "Construction drones, on the other hand, are light, mobile and flexible -- but so far they only exist at low technology readiness levels. They have yet to be used for industrial purposes."


MIT engineers develop a way to mass manufacture nanoparticles that deliver cancer drugs directly to tumors

Researchers developed a manufacturing technique that rapidly generates large quantities of nanoparticles coated with drug-delivering polymers, which hold great potential for treating cancer. The particles can be targeted directly to tumors, where they release their payload while avoiding many of the side effects of traditional chemotherapy.

Over the past decade, MIT Institute Professor Paula Hammond and her students have created a variety of these particles using a technique known as layer-by-layer assembly. They've shown that the particles can effectively combat cancer in mouse studies.
