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. ... >>

Eternal atomic battery 25.08.2020

The American startup NDB (Nano Diamond Battery) announced the successful laboratory testing of two prototypes of the so-called beta galvanic batteries (betavoltaic). Such batteries work on the principle of converting radioactive beta radiation into electrical current. It is argued that the development of NDB is unparalleled and will allow "forever" to supply energy to absolutely any device: from wearable sensors and smartphones to aircraft and even rockets.

Prototypes of the NDB battery have been tested at the Livermore National Laboratory and the Cavendish Laboratory at the University of Cambridge. Both labs confirmed that the charge collection efficiency of the Nano Diamond Battery reached record levels for so-called "diamond batteries" based on synthetic diamonds. So, if third-party developments show no more than 15% efficiency in energy production, then NDB prototypes demonstrated efficiency at the level of 40%.

An "atomic" battery is a radioactive core - a source of isotopes - coated with synthetic diamond. Isotopes interact with diamond in the process of inelastic scattering. This converts the radiation energy (beta radiation) into electrical current. Since the radioactive substance is capable of "radiating" for thousands of years, the life of such a battery will exceed all possible periods of operation of the equipment that they will feed.

For humans and the environment, such power sources are not dangerous. Radiation does not go outside, and the diamond shell of the rod serves as a guarantee against damage. The excess energy generated by the battery will accumulate in the buffer tank. The developers offer a supercapacitor for this, but the same lithium-ion battery can be used as a storage device. Imagine a smartphone no longer needs to be charged. It will become self-loading!

An agreement has been reached with two major manufacturers on joint "field" tests of the Nano Diamond Battery. The names of the companies are not disclosed. One of them is engaged in the production, maintenance and disposal of nuclear fuel products, and the second relates to the US military-industrial complex (defense and military production).
