Entertaining experiences at home / Chemistry experiments for children

In your free time, you decided to lie down on the grass. In this case, stains may appear on the clothes. It is unpleasant, ugly to walk in such clothes. It would be better if you, without delay, remove the stains yourself, especially since it will not take you much time. So, start removing grass stains from your clothes.

First, wipe the stain with a salt solution. To do this, first prepare it: take 2 parts by weight of table salt and 10 parts by weight of pure water. Remember that fresh grass stains on clothes also disappear after washing with hot water. If they do not disappear, use a solution of table salt, followed by washing with warm water.

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. ... >>

Flexible writable memory 31.01.2015

At one time, Thinfilm (Thin Film Electronics ASA) and Xerox's PARC research division developed a technology for continuous production by printing memory arrays on transistors from organic materials.

It was assumed that such a memory and the technology for its production would be suitable for creating things with an Internet connection for the production of extremely inexpensive electronics. In the meantime, as the official Thinfilm website informs us, mass stamped memory will be produced for rewritable stickers.

Under the agreement, Xerox will be responsible for rewritable memory labels. Lines at one of the company's factories in the state of New York will be adapted for this. Stickers will be issued in rolls.

This type of production promises a very low cost of each individual sticker. In addition, memory stickers by themselves will not work. Each of them only serves as a container for modules with RFID or NFC support.
