Researchers at the University of Rochester’s Institute of Optics have developed a new process that turns ordinary metal tubes unsinkable—meaning they will stay afloat no matter how long they are forced into water or how heavily they are damaged. The researchers describe their process for creating aluminum tubes with remarkable floating abilities in a study published in Advanced Functional Materials. By etching the interior of aluminum tubes, the researchers create micro- and nano-pits on the surface that turn it superhydrophobic, repelling water and staying dry.

Sunbeams contain a lot of energy. But current technology for harvesting solar power doesn’t capture as much as it could. Now, in ACS Applied Materials & Interfaces, researchers report that gold nanospheres, named supraballs, can absorb nearly all wavelengths in sunlight — including some that traditional photovoltaic materials miss. Applying a layer of supraballs onto a commercially available electricity converter demonstrated that the technology nearly doubled solar energy absorption compared to traditional materials.

Researchers at AppliedPhysics.org report early evidence that cells respond selectively to mathematically structured sound, not just acoustic power. In an exploratory Biosystems study, Fibonacci based acoustic signals triggered distinct responses across different cell types, suggesting sound can be tuned to cellular size and mechanics rather than applied as brute force.

The findings point to a potential new direction for cancer research: using low intensity, physics driven acoustic design to target physical differences between cancer and healthy cells. While preliminary and based on model organisms, the work opens the door to a future of more precise, less invasive, mechanically selective therapies.

Carbon nanohoops, or [n]cycloparaphenylenes ([n]CPPs), are ring-shaped molecules with exceptional optical properties but are difficult to synthesize and functionalize. Researchers in Japan have now used a gold-mediated synthetic strategy to construct a hexabrominated [9]CPP derivative, providing a versatile and scalable platform for post-functionalization. Using this scaffold, they created π-extended chiral nanohoops that exhibit extremely high g_lum value in their circularly polarized luminescence, opening new pathways for advanced optoelectronic materials and precisely designed nanocarbon architectures.

Junior-Professor Daqing Wang from the University of Bonn has received a Proof of Concept Grant from the European Research Council (ERC) for his “MinCryo” project. With the grant of 150,000 euros over one year, the physicist will continue to prepare his research results for practical applications in industry. The technical solution developed by him and his team facilitates a wider and more resource-efficient access to cryogenic – extremely cold - optical imaging that combines microscopes with extremely cold temperatures.

Universidad Carlos III de Madrid (UC3M) has been awarded a new Proof of Concept (PoC) grant by the European Research Council (ERC) in its latest call for the RT-FLOW project, led by Stefano Discetti from the Department of Aerospace Engineering at UC3M. The project aims to transform the way aerodynamic experiments are conducted by enabling near-instantaneous flow field measurements using compact hardware, thereby reducing both the time and cost of these tests.

Three projects by professors and researchers at the Politecnico di Milano have received funding under ERC Proof of Concept grants. PROTECT, by Alessandro Filippo Maria Pellegata (Department of Chemistry, Materials and Chemical Engineering), aims to fill a knowledge gap with respect to drug safety in pregnancy. META-SENSE, conducted by the Department of Physics and coordinated by Margherita Maiuri, aims to develop a nanosensor to detect PFAS. Finally, the goal of the LANTERN project is to develop a method for microchip nanofabrication. It is led by Edoardo Albisetti, a professor in the Department of Physics.
