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. ... >>

Production of hydrogen fuel from air 12.09.2022

Hydrogen has huge potential as a clean fuel: it is plentiful (mainly in compounds like water), produces no harmful emissions, and can be used to store energy from solar, wind and tidal sources.

However, there are problems with producing enough material in a practical and affordable way. Separating hydrogen from water can require complex technology, as well as clean fresh water, which is not available everywhere in abundance.

An international team of scientists has developed a new prototype device that can harvest water from moist air before splitting it into hydrogen and oxygen. What's more, it can work in places where humidity - the concentration of water vapor in the air - is as low as 4%.

The device assembled by the researchers is a prototype electrolyser powered by electricity from renewable energy sources to decompose water into its elements, hydrogen and oxygen. In one test, five electrolyzers were run in parallel with a solar power source. The electrodes sit on either side of a water collection device, a sponge-like material that absorbs water from the air but also serves as a reservoir for the electrolyte. Both electrodes are insulated from air, which means that hydrogen and oxygen can be collected as pure gases after separation has taken place.

A number of different materials and settings were tested to get the prototype device to perform at a satisfactory level, and one of the configurations the researchers tried was able to work successfully for 12 consecutive days.

"This so-called direct air electrolysis (DAE) module can operate in a completely dry environment with a relative humidity of 4%, overcoming water supply problems and producing green hydrogen sustainably with minimal environmental impact," they said.

The technology is still in its early stages, scientists say, because different DAE setups and materials have led to different results in terms of efficiency and power generation. However, the team is confident that their device can be improved and scaled.
