| Power at sea: Towards high-performance seawater batteries Posted: 31 Jan 2022 12:33 PM PST Despite the many potential applications of seawater batteries (SWBs), the limited performance of available materials has hindered their commercialization. To tackle this issue, scientists have developed a novel co-doped carbon material for the anode of SWBs. Their straightforward synthesis route and the high performance of the developed anode material will pave the way for the widespread adoption of SWBs, which are safer and less expensive than lithium-ion batteries. |
| Scientists use 'sticky' DNA to build organized structures of gel blocks Posted: 31 Jan 2022 10:28 AM PST Researchers have used microscopic strands of DNA to guide the assembly of gel blocks that are visible to the naked eye. |
| A new method for quantum computing Posted: 31 Jan 2022 08:04 AM PST Physicists have proposed a new architecture for a scalable quantum computer. Making use of the collective motion of the constituent particles, they were able to construct new building blocks for quantum computing that pose fewer technical difficulties than current state-of-the art methods. |
| 2D material in three dimensions Posted: 31 Jan 2022 08:04 AM PST For years, scientists have tried to develop 2D-materials such as graphene, which consists of only one layer of carbon atoms. But what if you need to fit as much graphene as possible into a limited space? Then the graphene layer has to be turned into a complex 3d shape. |
| Alternative technique for determining the true activity of catalysts Posted: 31 Jan 2022 05:38 AM PST Electrolysis of water into hydrogen and oxygen is a potential source of clean hydrogen fuel. However, the process requires efficient electrocatalysts. Unfortunately, conventional techniques often overestimate their efficiency. Now, researchers demonstrate an alternative technique for gauging the electrocatalytic performance accurately, opening doors to a smooth transition from lab-scale studies to large-scale hydrogen fuel generation and commercialization of new catalysts with no activity loss issues from overestimation of activity with transient voltammetry techniques. |
| Topology at the corner of the dining table Posted: 28 Jan 2022 11:13 AM PST A research team has discovered an unusual topological aspect of sodium chloride, commonly known as table salt, which will not only facilitate the understanding of the mechanism behind salt's dissolution and formation, but may also pave the way for the future design of nanoscale conducting quantum wires. |
