Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

carbon dioxide glass 18.01.2007

A group of chemists from the University of Florence (Italy) obtained a transparent glassy material from carbon dioxide by compressing "dry ice" between two diamond plungers under a pressure of 640 atmospheres at a temperature of 700 Kelvin.

Under such extreme conditions, CO2 molecules, which are characterized by double bonds of a carbon atom with each of the oxygen atoms, rearranged into molecules with single bonds, arranged randomly, as in ordinary glass. The resulting substance is about ten times harder than quartz, but softer than diamond. It is the hardest amorphous material known to science.

As soon as the pressure is removed, the extraordinary substance turns back into ordinary "dry ice" and then into gaseous carbon dioxide. But chemists suggest that if this "gas glass" is mixed with silicon dioxide at even higher temperatures, it will be possible to obtain an extremely hard glass-like substance that is stable under ordinary conditions. It will find application in technology, and in this form it will be convenient to store excess carbon dioxide, which is now emitted into the atmosphere and causing global warming.

Carbon and silicon are neighbors in the periodic table of the elements, but carbon dioxide under normal conditions is a gas, and silicon dioxide is either crystalline quartz or glass. It is assumed that high pressure changes the chemical properties of carbon towards silicon.
