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. ... >>
| Random news from the Archive A new way to chemically convert plastic into fuel
22.07.2019
One of the most acute and serious problems in the context of modern ecology on Earth is the problem of excessive amounts of plastic accumulating as waste and poisoning rivers, lakes, seas and large areas of land. According to modern data, already now the volume of this waste plastic reaches 5 billion tons, which is quite a critical indicator. And despite the fact that most experts suggest recycling this plastic, thus saving the earth's ecology from direct danger, there is still a more interesting way of recycling - it was proposed by a team of specialists from Purdue University, and it consists in transformation.
Namely, in the transformation of most types of plastic into the most useful fuel that can be used in a variety of spectrums and tasks. At the same time, it is worth noting that specialists invented and tested a new technological process for such a conversion of plastic into fuel, reminiscent of gasoline and diesel in its characteristics and properties. This technological process concerns the use of polypropylene as the final conversion product.
Polypropylene is a fairly common material, often found in children's toys, medical equipment and environmentally friendly devices, and as such is cheap and easy to change. As a transformational agent, scientists have proposed using so-called supercritical water - which has both the properties of a liquid and the properties of gases - by heating it between 716 and 932 degrees Fahrenheit at an average pressure 2,300 times that of deep sea pressure.
With such a chemical transformation of polypropylene, it becomes possible to convert plastic into fuel - especially since, according to experts, almost any plastic widely used in various fields is suitable for such a procedure. It remains to wait for news regarding the completion of the project.
