Scientists Are Developing Wafer-thin And Ferroelectric Nylon, Transparent Electronic Devices

Researchers at the Max Planck Institute in Mainz have developed and tested wafer-thin, ferroelectric nylon that is ideal for use with portable electronics. This could replace metal as the most used material for the production of portable electronics.

Nylon Instead Of Metal In The Production Of Portable Electronics

Portable and flexible electrical appliances are increasingly on the rise. Precisely because the portable electronics are still very error-prone and can be improved, new solutions are continually being researched. Currently, mostly metal is used for the production of the electrodes. However, other materials would be suitable, such as nylon. Nylon is particularly ideal because it is very flexible and stretchable, unlike the ceramic-based materials. Certain nylons have ferroelectric properties which are suitable for the production of sensors, storage, etc. are necessary. Another benefit of the nylon is that it can be processed more cost-effectively than most other materials.

Nylon-11 100 Times Thinner Than Human Hair

The large, more than the existing 40 years problem was that it failed to researchers, the so-called Nylon-11 light enough to manufacture. The layers were far too thick and were therefore unusable for the current technology. Now the researchers succeeded thin nylon films establish that nearly 100 times lighter areas the hair of a man. Another advantage in addition to the Flexibility and the thinness is the smoothness of the nylon layer. Which also this transparent makes and thus open electrical devices makes than wearables possible.

Researchers Find Nylon Capacitors as stable

The researchers at the Max Planck Institute for Polymer Research in Mainz who are working on the project have tested the ultra-thin nylon capacitors millions of times. The results show that the nylon is stable and will likely find application in flexible devices, robots, smart textiles, and biomedical devices in the future.

Researchers Create Microchip With Supercomputer Capability

MIT researchers has developed a “brain on-chip” which is smaller than a piece of confetti and that has tens of thousands of artificial brain synapses, known as memristors.

Not only the MIT develop a neuromorphic chip: Google, Microsoft, Intel, Apple, and Nvidia also these companies have their own machine learning hardware versions.

However, AI brain memristors use Silver. MIT researchers realized they could make each AI synapses either with silver and copper, along with silicon.

The United Arab Emirates Preparing Its First Mission To Mars

The United Arab Emirates Preparing Its First Mission To Mars

Mars is in the sights of Earth. In addition to the USA (with Mars 2020 ) and China (with Tianwen 1 ), another country this year will launch a mission towards the red planet: the United Arab Emirates (UAE).

If all goes well, in February next year the United Arab Emirates will be the fifth nation to successfully orbit Mars, in time for the celebration of the country’s 50th anniversary in December 2021.

According to Omran Sharaf, leader of the Hope mission, the goal is not simply to reach Mars. “It is part of something bigger: accelerating the development of our educational and academic sector” and generating knowledge that can be useful for the country in a future “post-oil” economy, from which most of its revenue currently comes from.

The mission aims to study the atmosphere of Mars, generating a map of its climate system over a Martian year, equivalent to 1.8 terrestrial years. Like Earth, Mars has seasons that influence winds, temperature, condensation and evaporation of ice, etc.

Most of the data we have comes from “one-off” observations, obtained from the equipment on the planet’s surface, which makes it difficult to construct a global climate panorama. To carry out its mission, Hope has three instruments mounted on an “arm”, capable of carrying out multiple measurements simultaneously: a camera sensitive to visible and ultraviolet light and spectrometers sensitive to infrared and ultraviolet light.

Its orbit around Mars lasts 55 hours and was calculated to offer two “points of view”: one where the planet rotates under the spacecraft, and the other where it tracks its speed of rotation, which allows it to observe a point static on the surface.

“This science was the sweet spot for us. We are complementary to other contemporary missions, so we maximize the global benefit that scientists will derive from our mission, which fuels other current areas of research and expands human knowledge as a whole, ”said the officials.

Hope’s launch is scheduled for July 14 this year. The mission will take off from the Tanegashima Space Center in Japan on an H-2A rocket built by Mitsubishi Heavy Industries.

Eye Has Self-cleaning System Similar To Brain, Says Research

Researchers have found that the eyes, as well as the brains of mice, have a self-cleaning system – and they believe this could also be applied to humans.

This type of maintenance is necessary to wash the cells and the residual fluids, and we know that the nervous tissue makes use of a small network of tubes known as the lymph system, similar to the lymphatic system that cleans the waste from the rest of the body.

New tests in mice and rats show that the structures at the back of the eyes – such as the optic nerve and the retina – channel the waste through a network much like the one the brain uses.

“Similar to the brain inside the cranial vault, the internal structures of the eye are contained in a confined space, requiring strict control of fluid homeostasis,” write the researchers in the article published in Science.

One of the main jobs of the system is to eliminate toxic beta-amyloid proteins that have been associated with the development of diseases such as Alzheimer’s, glaucoma, and age-related macular degeneration.

Although the research is based on mice and rats, and not on humans, these animals have similar eye configurations to ours – albeit on a more simplified level.

In addition, the discovery of the glymphatic system in the human brain was also inspired by experiments on mice – increasing the chances that, again, this is not just a rodent thing.

“It is the first time that someone has really shown the ocular glymphatic system as an additional pathway for the release of metabolites in the eye and relevant to beta-amyloid,” says neuroscientist Maya Koronyo-Hamaoui, the first researcher to associate protein deposits with Alzheimer’s.
