| Rusting iron can be its own worst enemy Posted: 21 Jan 2022 11:54 AM PST Atom-level simulations reveal the reason iron rusts in supposedly 'inert' supercritical carbon dioxide fluid. Trace amounts of water can cause a reaction at the interface between iron and the fluid, prompting the formation of corrosive chemicals. |
| New neutron-based method helps keep underwater pipelines open Posted: 21 Jan 2022 09:48 AM PST Industry and private consumers alike depend on oil and gas pipelines that stretch thousands of kilometers underwater. It is not uncommon for these pipelines to become clogged with deposits. Until now, there have been few means of identifying the formation of plugs in-situ and non-destructively. Measurements now show that neutrons may provide the solution of choice. |
| Posted: 21 Jan 2022 09:48 AM PST Scientists have made a discovery about the properties of water that could provide an exciting addendum to a phenomenon established over two centuries ago. The discovery also holds interesting possibilities for cooling devices and processes in industrial applications using only the basic properties of water. |
| Novel microscopic picoshell particles developed Posted: 20 Jan 2022 01:51 PM PST Bioengineers have created a new type of petri dish in the form of microscopic, permeable particles that can dramatically speed up research and development (R&D) timelines of biological products, such as fatty acids for biofuels. Dubbed PicoShells, the picoliter (trillionth of a liter), porous, hydrogel particles can enable more than one million individual cells to be compartmentalized, cultured in production-relevant environments, and selected based on growth and biomass accumulation traits using standard cell-processing equipment. |
| Smarter catalysts through 'induced activation' Posted: 20 Jan 2022 01:51 PM PST Researchers propose a novel method of significantly enhancing the catalytic efficiency of materials already in broad commercial usage, a process they have termed 'induced activation.' |
| Development of a lithium-air battery with an energy density over 500 wh/kg Posted: 20 Jan 2022 11:07 AM PST Researchers have developed a lithium-air battery with an energy density over 500Wh/kg -- significantly higher than currently lithium ion batteries. The research team then confirmed that this battery can be charged and discharged at room temperature. In addition, the team found that the battery developed by the team shows the highest energy densities and best cycle life performances ever achieved. These results signify a major step toward the practical use of lithium-air batteries. |
| Posted: 20 Jan 2022 11:07 AM PST An artificial pancreas is helping protect very young children with type 1 diabetes at a particularly vulnerable time of their lives. A study published today found that it is both safe to use and more effective at managing their blood sugar levels than current technology. |
| Advancing materials science with the help of biology and a dash of dish soap Posted: 20 Jan 2022 11:07 AM PST Scientists have finally found a way to probe delicate microcrystals with powerful X-ray laser beams. They say their method could help advance semiconductor and solar cell development. |
| Posted: 20 Jan 2022 11:07 AM PST Researchers discover crystalline zeolites in a nanotubular (1D) shape. |
| Creating sustainable material from waste Posted: 20 Jan 2022 10:51 AM PST A team of researchers looking for ways to upcycle biomass into new products has demonstrated that it is possible to efficiently turn industrially processed lignin into high-performance plastics, such as bio-based 3D-printing resins, and valuable chemicals. An economic and life-cycle analysis reveals the approach can be competitive with similar petroleum-based products, too. |
| Impossible material made possible inside a graphene sandwich Posted: 20 Jan 2022 07:34 AM PST Atoms bind together by sharing electrons. The way this happens depends on the atom types but also on conditions such as temperature and pressure. In two-dimensional (2D) materials, such as graphene, atoms join along a plane to form structures just one atom thick, which leads to fascinating properties determined by quantum mechanics. |
| Towards compact quantum computers thanks to topology Posted: 20 Jan 2022 07:34 AM PST Researchers at PSI have compared the electron distribution below the oxide layer of two semiconductors. The investigation is part of an effort to develop particularly stable quantum bits -- and thus, in turn, particularly efficient quantum computers. |
