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 Immortal quantum particles
21.06.2019
Theoretical physicists from the Technical University of Munich and the Institute for Physics of Complex Systems. Max Planck discovered that things that seem unthinkable in the everyday world are possible on a microscopic level.
“Until now it was assumed that quasiparticles in interacting quantum systems decay after a certain time. Now we know that the opposite is true: strong interactions can even completely stop the decay,” explains Frank Pollmann, professor of theoretical solid state physics at the Technical University of Munich. One example of such quasiparticles is a phonon - a quantum of vibrational motion of crystal atoms.
The concept of quasiparticles was invented by the physicist and Nobel Prize winner Lev Davydovich Landau. He used it to describe the collective states of many particles or, more precisely, their interactions under the influence of electric or magnetic forces. Due to this interaction, several particles act as one.
From a physical point of view, this oscillation is a wave that is transformed into matter, which, according to quantum mechanical wave-particle duality, is possible. Therefore, immortal quasiparticles do not violate the second law of thermodynamics. Their entropy remains constant, and decay is stopped.
This discovery also explains phenomena that have baffled scientists so far. Experimental physicists have measured that the Ba3CoSB2O9 magnetic compound is surprisingly stable. Magnetic quasiparticles - magnons - are responsible for this. Other quasi-particles - rotons - ensure that helium, which is a gas on the surface of the Earth, at absolute zero becomes a liquid that can flow indefinitely.
