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 Carbon nanotubes against water pollution by microplastics
07.08.2019
A new way to decompose microplastics could help clear waterways of these tiny bits of debris that could pose a health hazard to humans and other living beings.
Wastewater treatment plants are generally not equipped to filter microplastics. These harmful particles can break down naturally over decades, but new nanomaterials that produce plastic-degrading chemicals can break them down much faster. In preliminary tests, the nanomaterials cleared some water samples of about half their microplastic content in a matter of hours, the researchers report.
In the future, water treatment plants that use these nanomaterials could not only help prevent new microplastic pollutants from entering the environment, but also potentially remove particles from polluted waterways.
This water treatment method uses nitrogen-coated carbon nanotubes. When mixed with a compound called peroxymonosulfate, the nanotubes generate chemicals known as reactive oxygen species, which break down microplastics into smaller chemical components. Heating the water speeds up this process. The manganese embedded in each nanotube made the tubes magnetic, allowing them to be fished out of the water with magnets for reuse.
Jiang Kang, a chemical engineer at Curtin University in Perth, Australia, and colleagues tested their technique on 80 milliliter water samples contaminated with microplastic particles. Treatment of carbon nanotubes in water heated to 120°C for eight hours reduced the amount of microplastics in the water by about 30-50%.
The chemical by-products of this microplastic decomposition, such as aldehydes and carboxylic acids, do not pose a serious environmental hazard, says Long Chen, an environmental engineer at Northeastern University in Boston, who is not involved in the work. For example, Kang's team found that exposing green algae to water containing microplastic by-products for two weeks did not harm algae growth.
