An innovative material inspired by spider webs to solve the problem of plastic pollution

  • 3 תגובות
Researchers from the University of Cambridge have found a method for making biodegradable plastic from plant proteins common in nature that are a renewable material. Inspired by spider webs, the innovative plastic material behaves similarly to other types of plastic, and can even be broken down at home

Engineers have developed an innovative water treatment method that could help Mars explorers

  • No comments
A catalyst that breaks down a chlorine compound (perchlorate) in water could help clean the soil on the planet Mars during manned habitation on Mars. It is a substance that accumulates in plants and makes them toxic if it is not removed from the water with which they will water the plants that will be served by humans who will fly there

Molecular templates that will help identify extraterrestrial life forms will be used in the next spacecraft in the solar system

  • No comments
Future space exploration missions in the solar system will focus on the search for extraterrestrial life, led by Clipper Europa, which will fly to the large fair moon in 2024, but this life may not resemble life on Earth. A new analysis method of the mass spectroscopy type may allow the discovery of extraterrestrial life of the alien type

A new study conducted by a Belgian research team found that the metals iron and nickel are found in the atmospheres of comets traveling in our solar system, even those far from the sun. The findings were obtained with the help of data collected from the very large telescope which is located on the Cerro Paranal mountain, at an altitude of 2,635 meters in the Atacama Desert in northern Chile

The atomic structure of a single hole in a metal-organic framework shows how carbon dioxide molecules (gray and red spheres) bind to tetraamines (blue and white spheres), forming a polymer of carbon dioxide molecules that bind to the inner framework. Low-temperature steam can push the molecules of the gas apart, allowing the material to be used over and over to capture more and more carbon from power plant emissions [Courtesy: Eugene Kim]
