| Shape-memory alloys might help airplanes land without a peep Posted: 12 Jul 2021 03:33 PM PDT Having a home near a busy airport certainly has its perks. It is close to many establishments and alleviates the problem of wading through endless traffic to catch flights. But it does come at a cost -- tolerating the jarring sounds of commercial airplanes during landing and takeoff. Researchers have now conducted a computational study that validates using a shape-memory alloy to reduce the unpleasant plane noise produced during landing. |
| Posted: 12 Jul 2021 03:33 PM PDT Researchers have developed a new way to control and shape optical singularities. The technique can be used to engineer singularities of many shapes, far beyond simple curved or straight lines. It could be used for a wide range of applications from super resolution imaging to optical trapping. |
| Neutron-clustering effect in nuclear reactors demonstrated Posted: 12 Jul 2021 03:33 PM PDT The long-theorized neutron-clustering effect in nuclear reactors has been demonstrated, which could improve reactor safety and create more accurate simulations, according to a new study. |
| Discovery of 10 faces of plasma leads to new insights in fusion and plasma science Posted: 12 Jul 2021 03:33 PM PDT Scientists uncover new properties of plasma that have wide potential applications for astrophysical and fusion plasmas. |
| Magnetic field from MRI affects focused-ultrasound-mediated blood-brain barrier Posted: 12 Jul 2021 12:03 PM PDT Researchers have found that the magnetic field of the MRI scanner decreased the BBB opening volume by 3.3-fold to 11.7-fold, depending on the strength of the magnetic field, in a mouse model. |
| Posted: 12 Jul 2021 09:22 AM PDT The transportation sector is the largest contributor to greenhouse gas emissions in the United States, and a lot of attention has been devoted to electric passenger vehicles and their potential to help reduce those emissions. |
| Technology that restores the sense of touch in nerves damaged as a result of injury Posted: 12 Jul 2021 09:21 AM PDT Researchers have developed a sensor that can be implanted anywhere in the body -- for example, under the tip of a severed finger. The sensor connects to another nerve that functions properly and restores tactile sensation to the injured nerve. The development is biocompatible and does not require electricity, wires, or batteries. |
| Reviewing pressure effects on iron-based high-temperature superconductors Posted: 12 Jul 2021 07:22 AM PDT A new study reviews progress on high-pressure studies on properties of iron-based superconductor (ISBC) families, and examines the use of pressure as a versatile method for exploring new materials. |
| Giving a 'tandem' boost to solar-powered water splitting Posted: 12 Jul 2021 07:22 AM PDT Scientists combine two promising photocatalysts to obtain higher solar-to-hydrogen conversion efficiency and durability in a water splitting cell. |
| New electronic paper displays brilliant colors Posted: 12 Jul 2021 06:22 AM PDT Imagine sitting out in the sun, reading a digital screen as thin as paper, but seeing the same image quality as if you were indoors. It could soon be a reality. A new type of reflective screen - sometimes described as 'electronic paper' - offers optimal color display, while using ambient light to keep energy consumption to a minimum. |
