Take three dry glass cups, warm them by the stove, put them on the table and cover them with a metal tea tray, also slightly heated by the stove (not in a microwave oven!). Electrify a sheet of newspaper, fold it in half, rub it again and place it on a tray. Now bring some metal object to it - a key or a teaspoon. A long spark will fly between the tray and the key and a crack will be heard.

After removing the newspaper, you will again get the same effect when the key approaches the tray. If a newspaper is placed on the tray several times, the spark will be drawn again, each time decreasing in length and brightness.

Hold an electrified newspaper near the base of a light bulb. You will see an electrical glow inside the cone. A particularly bright glow will be if you put an electric lamp on a tray that was electrified earlier.

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 ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

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. ... >>

Embroidery of electrons by ion 26.03.2010

The process of autoionization became known not yesterday. Its essence is that if an electron is knocked out of a molecule using X-rays, then after a few femtoseconds another electron will be released.

Clarity in the details of this process was made by German physicists from the Max Planck Institute for Plasma Physics and the Fritz Haber Institute. They irradiated small pieces of ice with soft x-rays from a synchrotron source and received electron pairs.

It turned out that the second electron does not fly out from the same water molecule that was excited by the absorption of an X-ray photon. Having emitted the first electron, it removes the remaining excitation in a very specific way - passing it on to another molecule, and that one loses its electron. The transfer of excitation occurs in a non-contact way. This phenomenon is called "intermolecular Coulomb decay".

“The appearance of a cascade of slow electrons during irradiation makes it possible to better understand why high-energy rays are detrimental to living beings. After all, as it was established several years ago, once in an organic molecule, such an electron is able to cut it like scissors,” says Uwe Hergenhan, a participant in the work.
