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 Shrimp will help in the extraction of uranium 06.09.2012 In an attempt to make it easier for the shrimp and crab industry to dispose of the shells, scientists unexpectedly discovered a cheap way to extract uranium from seawater. As you know, the reserves of uranium ore on Earth may soon run out, which will put an end to obtaining energy using nuclear power plants. However, there is another, practically inexhaustible, billions of tons, source of uranium - ocean water. But since the content of uranium in it does not exceed 3,3 milligrams per ton, its extraction remains unprofitable today. Chemists have been struggling with this problem for a long time and have made some progress in recent years. The best results were obtained by Japanese researchers at the beginning of the 2003st century. They created a mat of plastic fibers impregnated with molecules that both bound the fibers and absorbed the uranium. In 100, with the help of such a mat, the Japanese "got" a kilogram of uranium out of the water. Such carpets up to 200 meters long can be lowered to a depth of XNUMX meters. They are taken out of the water, washed with an acid solution to release the uranium, and put back into the water. Various laboratories tried to improve the performance of the "uranium" mat by adding porous "nanoparticles" of silicon oxide or carbon to its composition, but the first serious result was achieved by a team of chemists from the University of Alabama using polymers obtained from shellfish shells. This group worked under contract with a company that manufactures products from crab and shrimp. The organization was so interested in resolving the issue of shell disposal as soon as possible that it was ready to pay hundreds of thousands of dollars for it. Scientists have developed an appropriate method, having found that the "ionic liquid" - molten salt - is able to extract chitin from the shells. It was also found that chitin is not only the basis of the shells, but is also an ideal means for accumulating uranium, and is very easily and firmly "embedded" in the composition of the fibers of the "uranium" mat. According to Dr. Robin Rogers, who leads the research team, their mat is capable of collecting twice as much uranium as a Japanese one. This brings it closer to the standards of industrial use, although, says Rogers, their results "are not yet very good for the modern economy." He, nevertheless, is sure that by modernizing the received methodology, his group will be able to find a way out.
