Stanford engineers find that cancer cells exhibit a unique mode of migration on squishy materials, which are similar to biological tissues. In contrast, cell movement - a process central to cancer metastasis and other biological processes - is typically studied on very rigid materials.
A team at HZB, together with partners from Ben Gurion University and the Technion, Israel, has now analysed the optoelectronic properties of rust (haematite) and other metal oxides in unprecedented detail. Their results show that the maximum achievable efficiency of haematite electrodes is significantly lower than previously assumed. The study demonstrates ways to assess new photoelectrode materials more realistically.
A new paper in the journal Science co-authored by Princeton University engineering professor Nathalie de Leon, IBM Quantum scientist Hanhee Paik and researchers from around the world argues that the ability to move forward on developing useful quantum computers requires new major advances in materials science, engineering and fabrication. The authors call for new approaches from broad areas of science and engineering.
Scientists have identified the primary cause of failure in a state-of-the-art lithium-metal battery, of interest for long-range electric vehicles: electrolyte depletion.
Using machine learning methods, researchers at TU Graz can predict the structure formation of functionalized molecules at the interfaces of hybrid materials. Now they have also succeeded in looking behind the driving forces of this structure formation.
The study reveals that distinct types of active LC systems all exhibit striking similarities with one another but they also exhibit a high sensitivity to the environment, making them potentially programmable and autonomous for a wide range of applications.
Someday, scientists believe, tiny DNA-based robots and other nanodevices will deliver medicine inside our bodies, detect the presence of deadly pathogens, and help manufacture increasingly smaller electronics. Researchers took a big step toward that future by developing a new tool that can design much more complex DNA robots and nanodevices than were ever possible before in a fraction of the time.
Scientists have for the first time captured the complex dynamics of particle movement in granular materials, helping to explain why mixed nuts often see the larger Brazil nuts gather at the top. The findings could have vital impact on industries struggling with the phenomenon, such as pharmaceuticals and mining.
The project was kickstarted in 2017 when a delegation of YTC America (subsidiary of Yazaki Corporation) visited Kazan Federal University. During the talks, YTC suggested that KFU participate in developing effective methods of separating single-wall carbon nanotubes (SWCNTs) into metallic and semiconducting specimens. This was to be done on Tuball tubes produced by OCSiAl, since they are the only ones currently available in industrial quantities.
Researchers discovered, while exploring the photomechanical properties of diarylethene, that under irradiation with UV light the crystal of the compound peels off into micrometer-sized crystals at a world's fastest speed of 260 microseconds. As the material returns to its former molecular structure when exposed to visible light, the exfoliation method positions itself as a candidate for photoactuator manufacturing.
