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. ... >>

Advanced EV batteries from QuantumScape 12.12.2020

QuantumScape's solid-state lithium metal batteries promise to be second-generation electric vehicle batteries with range comparable to ICE vehicles.

Previously, solid state lithium metal batteries were considered promising, but suffering from a lot of negative side effects. In particular, they were safer and more capacious than lithium-ion, but had a narrow operating temperature range. QuantumScape batteries are said to be free from the childhood ailments of solid-state lithium metal batteries and could be commercially viable in as little as four years.

New batteries do not have an anode. More precisely, in the production of QuantumScape batteries, the anode is not manufactured. This electrode is formed in an already assembled battery cell by deposition of lithium metal during the cell charging process. The claimed lithium deposition rate during anode formation surpasses all previous figures and reaches one micron per minute, which promises high charging current density and fast charging: up to 80% capacity in 15 minutes.

The battery anode is designed with "zero excess lithium". In other words, even a minimal amount of lithium in the form of foil or deposition at the site of anode formation is not necessary during the production of the cell. This significantly reduces the cost and simplifies the production of cells.

Another important invention of QuantumScape was the creation of a ceramic separator that separates the electrodes. The QuantumScape separator is thinner than a human hair and non-flammable. In a conventional lithium ion cell, the separator is made from organic materials and is one of the reasons for the fire hazard of the cells. It should be noted that the QuantumScape battery cells will be made in the form of "bags", and not in a cylindrical form factor. Perhaps this is one of the features of the use of ceramic separators.

QuantumScape batteries also boast thick cathodes capable of handling high density currents in excess of 3 mAh/cm2 for an hour of charging and discharging at 1C currents. After going through 800 charge and discharge cycles, the QuantumScape cells retained over 80% capacity, potentially promising hundreds of thousands of miles on a single battery. More importantly, the batteries maintain their performance down to -30°C, which was not possible with alternative designs. Also, due to the fact that graphite or graphite-silicon is removed from the anode, the electrolyte substance does not degrade during side reactions in the processes of charging and discharging the cell. This keeps the operating parameters of the cell as long as possible.

QuantumScape promises to bring the capacity of commercial solid-state lithium metal batteries to the lab-tested maximum of 1000 Wh/L. Thus, battery capacity can increase by 80% compared to the best modern lithium-ion cells and bring the range of electric vehicles to values comparable to the capabilities of cars with internal combustion engines.
