If you are trying to make a wound dressing that is best suited for the human body, it would be most logical to use materials of human origin. This is the approach that German researchers used to create a bandage based on tropoelastin.
Krasnoyarsk scientists have obtained new promising thin films made of oxygen, copper and titanium nitride. Their electrical resistance is a thousand times less than that of ordinary titanium nitride. Based on the obtained material, physicists have discovered new properties of copper that allow it to accumulate on the surface of films and make phase transitions. The results obtained can become a technological breakthrough in the development of resistors and transistors of a new generation.
For the second summer in a row, the planet is enveloped in clouds of smoke caused by forest fires. The clouds are so big that they can even affect the weather, create lightning and paint the skies in different colors. Smoke contains dangerous particles that threaten our health. Unfortunately, they cannot be contained.
As a widely used material worldwide, cement has a huge impact on the environment and accounts for about eight percent of our CO2 emissions, but scientists hope to solve this problem by making changes to the composition of the material.
Materials that change their properties in response to certain stimuli can occupy a valuable niche in many fields, from robotics to medicine and modern aircraft. A new example of such a shape-shifting technology was presented in the form of an imitation of ancient chain mail armor, which allows you to quickly switch from a flexible version to a rigid one due to the features of the material.
Stopping bleeding due to injury can save lives, but due to the abundance of blood, many patches and bandages simply refuse to stick to the skin. Researchers at the Massachusetts Institute of Technology have developed a new surgical adhesive that can stop bleeding within 30 seconds.
ETH Zurich engineers have developed a new, surprisingly simple method of combining two metals into one nanocrystalline structure.
Researchers from the Massachusetts Institute of Technology have found another use for graphene by making a reusable filter from its oxide foam, which acts as a magnet for uranium, effectively pulling the radioactive element out of drinking water.
New research has refuted the presence of liquid water under the surface of Mars. Water vapor circulates in the moon's atmosphere. In one day, the Greenland ice sheet lost 22 gigatons of ice. The lower the level of the world ocean, the higher the activity of volcanoes.
Although optical fibers are very efficient at transmitting data, they are also very fragile, and therefore can be unreliable. A new experimental type of optical fiber eliminates this limitation by using a core of liquid glycerin.
