May 25, 2022 (Nanowerk News) Cilia are the body’s diligent ushers. These microscopic hairs, which move fluid by rhythmic beating, are responsible for pushing cerebrospinal fluid in your brain, clearing the phlegm and dirt from your lungs, and keeping other organs and tissues clean. A technical marvel, cilia have proved...
How concrete 3D printing saves material and CO2
May 25, 2022 (Nanowerk News) Concrete is the most widely used building material in the world. It can be used in many ways, can be produced locally and is very durable. Its environmental performance, on the other hand, is the subject of critical debate. In particular, the production of the...
Crystallization of nickel out of liquid observed in real-time at the atomic level
May 25, 2022 (Nanowerk News) The potential use of nickel in new nanomaterials and as a low-cost catalyst in chemical reactions serving a range of industrial processes has been held back by a limited understanding of fundamental aspects of how the metal crystallizes into a solid. Researchers however have now...
Researchers develop new biobattery for hydrogen storage
May 25, 2022 (Nanowerk News) A team of microbiologists from Goethe University Frankfurt has succeeded in using bacteria for the controlled storage and release of hydrogen. This is an important step in the search for carbon-neutral energy sources in the interest of climate protection. The corresponding paper has now been...
Full-body synchrotron imaging of roundworms reveals nanoparticle accumulation
May 25, 2022 (Nanowerk News) Scientists working at DESY’s PETRA III light source have been able to generate the first synchrotron-based X-ray map of the whole body of an organism at such a high resolution that contaminants could be detected at the individual cell level. The research team was able...
Scientists build subcellular map of entire brain networks
May 25, 2022 (Nanowerk News) Researchers at the Francis Crick Institute have developed an imaging technique to capture information about the structure and function of brain tissue at subcellular level – a few billionth of a metre, while also capturing information about the surrounding environment. The unique approach detailed in...
Custom ‘headphones’ boost atomic radio reception 100-fold
May 25, 2022 (Nanowerk News) Researchers at the National Institute of Standards and Technology (NIST) have boosted the sensitivity of their atomic radio receiver a hundredfold by enclosing the small glass cylinder of cesium atoms inside what looks like custom copper “headphones.” The structure — a square overhead loop connecting...
Low-cost gel film can pluck drinking water from desert air
May 24, 2022 (Nanowerk News) More than a third of the world’s population lives in drylands, areas that experience significant water shortages. Scientists and engineers at The University of Texas at Austin have developed a solution that could help people in these areas access clean drinking water. The team developed...
Tech firms are making computer chips with human cells
May 24, 2022 (Nanowerk Spotlight) The year is 2030 and we are at the world’s largest tech conference, CES in Las Vegas. A crowd is gathered to watch a big tech company unveil its new smartphone. The CEO comes to the stage and announces the Nyooro, containing the most powerful...
Secret to treating ‘Achilles heel’ of perovskites in solar cells
May 24, 2022 (Nanowerk News) A team of researchers from the UK and Japan has found that the tiny defects which limit the efficiency of perovskites – cheaper alternative materials for solar cells – are also responsible for structural changes in the material that lead to degradation. The researchers used...
