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. ... >>

Silicon nanotube anodes triple the capacity of lithium-ion batteries 07.06.2014

Scientists at the University of California have developed an improved technology for manufacturing lithium-ion batteries. It allows you to triple the battery capacity.

By creating anodes for lithium-ion batteries from silicon dioxide, the developers found a three-fold increase in capacity compared to existing analogues that use carbon.

Silicon dioxide has been used previously as an anode material in lithium-ion batteries. However, the possibilities of obtaining specific unified nanostructures from this material with the required high energy density and long life cycle were limited. Developers were originally focused on using SiO2 as it is an extremely common and environmentally friendly compound.

According to Zachary Favors, part of the research team, they have taken a material used in medical devices, children's toys and even fast food, and modified it for use in next-generation batteries.

Significant stability of silicon nanotubes in the battery makes it possible to increase the service life. During the experiments, 100 full charge/discharge cycles of batteries with SiO2 nanotube anodes were carried out without any loss of energy capacity. Scientists are confident that new batteries will be able to be recharged hundreds of times without losing capacity.

The research of scientists is important for industry, incl. for various electronics and electric vehicles.
