| Touted as clean, 'blue' hydrogen may be worse than gas, coal, researchers say Posted: 12 Aug 2021 01:19 PM PDT 'Blue' hydrogen -- an energy source that involves a process for making hydrogen by using methane in natural gas -- is being lauded as a clean, green energy to help reduce global warming. But authors of a new report believe it may harm the climate more than burning fossil fuel. |
| The Wendelstein 7-X concept proves its efficiency Posted: 12 Aug 2021 10:59 AM PDT One of the most important optimization goals underlying the Wendelstein 7-X fusion device has now been confirmed. An analysis shows: In the optimized magnetic field cage, the energy losses of the plasma are reduced in the desired way. Wendelstein 7-X is intended to prove that the disadvantages of earlier stellarators can be overcome and that stellarator-type devices are suitable for power plants. |
| Toward next-generation brain-computer interface systems Posted: 12 Aug 2021 10:59 AM PDT A new kind of neural interface system that coordinates the activity of hundreds of tiny brain sensors could one day deepen understanding of the brain and lead to new medical therapies. |
| Materials science engineers strive to reduce emissions from aircraft engines Posted: 12 Aug 2021 09:31 AM PDT Engineers found a way to greatly extend the life of materials used in jet engines. |
| New study shows the potential of DNA-based data-structures systems Posted: 12 Aug 2021 09:31 AM PDT Engineers have created new dynamic DNA data structures able to store and recall information in an ordered way from DNA molecules. They also analyzed how these structures are able to be interfaced with external nucleic acid computing circuits. |
| Over 260,000 kilometers of rivers at risk due to proposed hydro dams Posted: 12 Aug 2021 09:30 AM PDT Over 260,000 kilometers of river could potentially be severed by planned hydroelectric developments according to researchers. The Amazon, the Congo, and the Irrawaddy are just a few of the rivers at risk of losing their free-flowing status if the proposed construction of new hydro power dams takes place. The study showed that planned dams and reservoirs are leading contributors to the decline of free-flowing rivers around the world. It also provides a comprehensive list of science-based solutions to minimize the impacts of hydro power development in rivers. |
| One-dimensional red phosphorus glows in unexpected ways Posted: 12 Aug 2021 07:34 AM PDT Researchers have now found that fibrous red phosphorus, when electrons are confined in its one-dimensional sub-units, can show large optical responses -- that is, the material shows strong photoluminescence under light irradiation. The study shows that strong optical properties exist in a 1D van der Waal material. |
| Posted: 12 Aug 2021 06:27 AM PDT Scientists used a new system to zoom in on an iconic RNA catalyst and a piece of viral RNA that's a potential target for COVID-19 treatments. |
| Silica nanostructure with chemo-enzymatic compartmentalization Posted: 12 Aug 2021 06:27 AM PDT A research team has recently synthesized a chemo-enzymatic nanostructure that can selectively synthesize one enantiomer while acting like an artificial organelle in the cell. |
| Scientists develop chain mail fabric that can stiffen on demand Posted: 11 Aug 2021 10:15 AM PDT Scientists have developed a new type of 'chain mail' fabric that is flexible like cloth but can stiffen on demand. The lightweight fabric is 3D-printed from nylon plastic polymers and comprises hollow octahedrons (a shape with eight equal triangular faces) that interlock with each other. When encased in a plastic envelope and vacuum-packed, it becomes 25 times more rigid and can hold up over 50 times its own weight. |
| Gen Z willing to rent clothes to reduce waste Posted: 11 Aug 2021 10:15 AM PDT Gen Z adults are interested in using apparel rental services to reduce overconsumption, according to a new study. Apparel rental, also known as collaborative apparel consumption, extends the life of an article of clothing because people don't throw it away after wearing it a few times. |
| Enabling the next generation of organic solar cells Posted: 11 Aug 2021 10:15 AM PDT Researchers have discovered a new, faster way in which organic materials redistribute sunlight energy, which could enable the next generation of organic solar cells to convert sunlight into electrical power and help in the battle against climate change. |
| Switched on IR-active organic pigments Posted: 09 Aug 2021 07:58 AM PDT In photosynthesis and organic photovoltaics, pigment molecules convert light into electrical charge. Chemists have now produced an unusual organic pigment, which is 'switched on' by an electrical charge to become a potent dye that absorbs light in the near-infrared range. The team's study suggests electrophysical materials research, photovoltaics, and sensor technology. |
