| Self-propelled, endlessly programmable artificial cilia Posted: 05 May 2022 05:59 PM PDT Researchers have developed a single-material, single-stimuli microstructure that can outmaneuver even living cilia. These programmable, micron-scale structures could be used for a range of applications, including soft robotics, biocompatible medical devices, and even dynamic information encryption. |
| Scientists observe quantum speed-up in optimization problems Posted: 05 May 2022 12:03 PM PDT Scientists have demonstrated a breakthrough application of neutral-atom quantum processors to solve problems of practical use. |
| Mechanism 'splits' electron spins in magnetic material Posted: 05 May 2022 11:38 AM PDT Holding the right material at the right angle, researchers have discovered a strategy to switch the magnetization in thin layers of a ferromagnet -- a technique that could eventually lead to the development of more energy-efficient magnetic memory devices. |
| 'Metalens' could disrupt vacuum UV market Posted: 05 May 2022 11:38 AM PDT Photonics researchers have created a potentially disruptive technology for the ultraviolet optics market. Solid-state 'metalens' transform long-wave UV into focused 'vacuum UV,' a type of light used in semiconductor manufacturing that is costly, in part because it is absorbed by almost all types of glass used to make conventional lenses. |
| New shape memory alloy discovered through artificial intelligence framework Posted: 05 May 2022 11:38 AM PDT Researchers used an Artificial Intelligence Materials Selection framework (AIMS) to discover a new shape memory alloy. The shape memory alloy showed the highest efficiency during operation achieved thus far for nickel-titanium-based materials. In addition, their data-driven framework offers proof of concept for future materials development. |
| The mystery solved about the active phase in catalytic carbon dioxide reduction to methanol Posted: 05 May 2022 11:37 AM PDT Researchers have been able to study the surface of a copper-zinc catalyst when carbon dioxide is reduced to methanol. A better knowledge of the catalytic process and the possibility of finding even more efficient materials opens the door for a green transition in the chemical industry. |
| Understanding how sunscreens damage coral Posted: 05 May 2022 11:32 AM PDT Researchers reveal a mechanism by which oxybenzone, a common sunscreen component, damages corals. The surprising findings could help guide the development and marketing of effective, coral-safe sunscreens. |
| Newly proposed search strategies improve computational cost of the bicycle-sharing problem Posted: 05 May 2022 08:47 AM PDT Bicycle sharing is an attractive zero-carbon transportation option for a world that is being increasingly disrupted by climate change. But bikes need to be restored at bike ports every now and then. Calculating the optimal way to restore bicycles is time consuming and computationally expensive. Recently, researchers have built upon their previous optimization algorithm to propose two strategies to reduce computational costs while maintaining the performance of the algorithm. |
| Researchers now able to predict battery lifetimes with machine learning Posted: 05 May 2022 08:46 AM PDT Scientists have used machine learning algorithms to predict how long a lithium-ion battery will last. |
| 'Nanomagnetic' computing can provide low-energy AI Posted: 05 May 2022 08:46 AM PDT Researchers have shown it is possible to perform artificial intelligence using tiny nanomagnets that interact like neurons in the brain. |
| 'Smart' diaper for bedside urine testing Posted: 05 May 2022 08:46 AM PDT Urine can reveal a lot about a person's health. But physicians don't currently have a convenient or fast way of tracking the concentration of important compounds in their patients' urine. Now, researchers have designed a flexible sensor that fits in a diaper, measures multiple components in urine and can share those results over Bluetooth to provide real-time bedside analyses for incontinent, elderly or infant patients. |
| Wearable, inexpensive robotic sleeve for lymphedema treatment Posted: 05 May 2022 08:46 AM PDT Researchers have developed a soft robotic sleeve controlled with a microfluidic chip that reduces cost, weight, and power consumption for treatment of lymphedema. The prototype is more portable than previous devices, and the underlying mechanisms can extend to other treatments, such as prosthetics. The microfluidic chip has 16 channels, each with a different resistance. The differing resistances create a time delay between the flow through each channel, causing balloons in the sleeve to sequentially inflate and push fluid upwards, out of the arm. |
| Researchers create flat magic window with liquid crystals Posted: 05 May 2022 07:21 AM PDT Researchers have used liquid crystals to create a flat magic window -- a transparent device that produces a hidden image when light shines on it. The process for creating transparent liquid crystal magic windows can produce any desired image. The process can also be used to create magic mirrors that reflect, rather than transmit, light to create an image. The technology represents a new twist on a very old light trick, originating thousands of years ago in China and Japan. |
