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. ... >>

Structural paint 05.01.2015

Many beetles and butterflies are colored without the use of dyes - due to the fact that nanostructures are located on the surface of the elytra of the first and the wings of the second, which convert white light into colored light. If a person could learn how to apply a similar method on an industrial scale, he would get rid of the need to deal with a huge variety of substances. In addition to saving on production, the task of subsequent processing is also simplified.

A step in this direction was taken by researchers from the Technological University of Denmark, led by Asger Mortensen. With the help of structural coloring, they depicted the emblem of their institute on the polymer.

First, they made a silicon stamp from periodically spaced cylindrical pits a few tens of nanometers in diameter. Then this stamp was printed on the surface of the polymer. A layer of aluminum 20 nm thick was applied to the resulting relief, and aluminum disks 50 nm high were obtained. The image has appeared! Depending on the diameter of the disks and the distance between them, some areas turned out to be yellow, others - blue.

The protective clear coat shifted the colors to the red side, but the effect did not disappear. The main cost, of course, is the production of the die, and the rest of the processes are cheap enough to allow mass production of multi-colored polymers without ink.
