Jan 14, 2022 (Nanowerk News) A world-first study has revealed how space travel can cause lower red blood cell counts, known as space anemia. Analysis of 14 astronauts showed their bodies destroyed 54 percent more red blood cells in space than they normally would on Earth, according to a study...
Photon recycling – the key to high-efficiency perovskite solar cells
Jan 13, 2022 (Nanowerk News) Scientists from TU Dresden, in cooperation with researchers at Seoul National University (SNU) and Korea University (KU), demonstrated the role of the re-use of photons (known as ‘photon recycling’) and light scattering effects in perovskite solar cells, providing a pathway towards high-efficiency solar energy conversion....
New insights into seasons on a planet outside our solar system
Jan 14, 2022 (Nanowerk News) Imagine being in a place where the winds are so strong that they move at the speed of sound. That’s just one aspect of the atmosphere on XO-3b, one of a class of exoplanets (planets outside our solar system), known as hot Jupiters. The eccentric...
New fluorescent nanovesicles for intracellular biomarker detection
Jan 14, 2022 (Nanowerk News) A new work by the Nanomol Group, belonging to the CIBER-BBN network, at the Institute of Materials Science of Barcelona (ICMAB-CSIC), together with a team from the University of Rome Tor Vergata, presents new nanovesicles capable of crossing biological barriers such as cell membranes, while...
Creating a reference map to explore the electronic device mimicking brain activity
Jan 14, 2022 (Nanowerk News) Just like explorers need maps, scientists require guides to better understand and advance new technology. A neuromorphic device, which can mimic the neural cells in our brain, has lacked such a guideline and created headaches for scientists trying to understand their operational mechanisms. That is...
Researchers use ghost imaging to speed up x-ray fluorescence chemical mapping
Jan 13, 2022 (Nanowerk News) Researchers have developed a new, focus-free technique for creating chemical maps using x-ray fluorescence. The approach offers fast, high-resolution measurements, which could be useful for analyzing chemical composition for a range of applications in biomedicine, materials science, archeology, art and industry. “Our new method combines...
Bioengineered nanoparticles show promise for fibrinogen manufacture
Jan 13, 2022 (Nanowerk News) A couple of essential biomolecules play a key role in the process of blood clotting. One of these is a protein called fibrinogen. It is often given to those who have experienced heavy bleeding, like trauma patients. But the fibrinogen concentrate that can be given...
Have astronomers finally found an exomoon? (w/video)
Jan 13, 2022 (Nanowerk News) Astronomers have reported a second, super-sized moon orbiting a Jupiter-sized planet beyond our solar system. If confirmed, the sighting could mean that exomoons are as common in the universe as exoplanets, and that big or small, such moons are a feature of planetary systems. But...
Tuning the bonds of paired quantum particles to create dissipationless flow
Jan 13, 2022 (Nanowerk News) Electrons flowing through power lines and computers inevitably encounter resistance; when they do, they lose some of their energy, which dissipates as heat. That’s why laptops get hot after being used for too long and why the server farms that power the cloud require so...
Study reveals how to break symmetry in colloidal crystals
Jan 13, 2022 (Nanowerk News) Nature keeps a few secrets. While plenty of structures with low symmetry are found in nature, scientists have been confined to high-symmetry designs when synthesizing colloidal crystals, a valuable type of nanomaterial used for chemical and biological sensing and optoelectronic devices. Now, research from Northwestern...
