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. ... >>

New form of magnetism discovered 21.11.2023

A research team from ETH Zurich has announced the revolutionary discovery of a new type of magnetism. The experimental results indicate that an artificially created material can acquire magnetic properties through a previously unknown mechanism.

The experimental discovery of a new form of magnetism in moiré materials opens up new perspectives in understanding the magnetic properties of materials. The results obtained allow us to consider possible applications of this phenomenon in future technologies and the creation of new materials with unique magnetic properties.

A known form of magnetism, which occurs when magnets stick to refrigerators, for example, is called ferromagnetism and occurs when all the electrons in a material spin in the same direction. However, there are other forms such as paramagnetism, which is a less intense version and occurs when electrons spin in random directions.

In a new study, scientists from ETH Zurich investigated the magnetic properties of moire materials, experimental compositions created by incorporating two-dimensional sheets of molybdenum diselenide and tungsten disulfide. These materials have a lattice structure capable of containing electrons.

To determine the type of magnetism in these moire materials, the researchers introduced electrons into them using an electric current, increasing the voltage. Then, to measure magnetism, they pointed a laser at the material and measured how much light was reflected for different polarizations, which allows them to determine whether the electrons were spinning in the same direction (indicating ferromagnetism) or in random directions (indicating paramagnetism).

The material initially showed signs of paramagnetism, but as more electrons were added to the lattice, it suddenly and unexpectedly transitioned to a state of ferromagnetism. Interestingly, this shift occurred precisely when the lattice contained more than one electron per site, excluding exchange interaction, the usual mechanism responsible for ferromagnetism.

Scientists have proposed an alternative mechanism: when more than one electron hits lattice sites, they combine into particles known as "doublons" that eventually fill the entire lattice through quantum tunneling. In the process, the electrons minimize their kinetic energy, aligning their spins and thus creating ferromagnetism. Such "kinetic magnetism" has been theorized for decades, but has not previously been seen in solid materials.
