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 Sweets from the Christmas tree
01.01.2019
The needles of Christmas trees, and indeed any other, trees consist of hundreds of thousands of needles, which decompose in much the same way as other tree leaves. When they rot, they release huge amounts of greenhouse gases. Scientists from the University of Sheffield have discovered that more useful substances can be obtained from decomposition products.
The main component (up to 85 percent) resulting from the decomposition of needles is a complex polymer known as lignocellulose. Its complexity makes the use of needles as a raw material unattractive for modern industry.
The research that has been done has revealed an industrially viable way to break down this complex structure into simpler substances such as sugars and phenols. With the help of heat and solvents such as glycerin, which is cheap and environmentally friendly, spruce needles are decomposed into a liquid product (bio oil) and a solid by-product (biochar).
Bio oil usually contains glucose, acetic acid and phenol. These chemicals are used in many industries - glucose in food sweeteners, acetic acid in paint, glue, and even vinegar.
The process is waste-free as the solid by-product can also be useful in other industrial chemical processes. You can use both fresh and old, abandoned Christmas trees.
