Comments on the article

In order for products from paper and papier-mâché impart mother-of-pearl look, they are covered with a mixture of 100 wt. hours of barium sulphate salt, 2000 wt. hours of water 15 wt. including gelatin. It is recommended to add some fish scale pearl essence to this mixture.

Papier-mache products can be given a mother-of-pearl look if mica flour is added to the paper pulp. Mica flour can be prepared as follows.

Mica is burned in a muffle furnace and crushed in a mortar and paint grinder into a fine, well-ground powder. Then it is treated with tin salt vapors. Finished products are coated with lacquer.

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. ... >>

Transistors that work 10 times faster than brain synapses 03.08.2022

Researchers at the Massachusetts Institute of Technology have developed programmable transistors that operate 10 times faster than brain synapses. The technology used for analog machine learning provides not only high data processing speed, but also good energy efficiency.

The working mechanism of the device is to electrochemically insert a tiny ion, a proton, into an insulating oxide to modulate its electronic conductivity. Scientists used a powerful electric field to accelerate protons and put ion transistors into nanosecond mode of operation.

The researchers note that the secret of new devices in the use of inorganic phosphorus silicate glass. It provides ultra-fast movement of protons, since it contains many nanometer-sized pores, the surfaces of which provide diffusion paths for elementary particles. It can withstand very strong pulsed electric fields.

The action potential in biological cells rises and falls on a time scale of milliseconds as a potential difference of approximately 0,1 volts is limited by the stability of water. In our work, we apply up to 10 volts through a special, nano-thick, hard glass film that produces protons without damaging it. And the stronger the field, the faster the ion devices work.

In the human brain, learning occurs by strengthening and weakening connections between synapses. Deep neural networks use a similar strategy when the weights of the nodes (neurons) are programmed with learning algorithms. When using processors, increasing and decreasing the electrical conductivity of proton resistors provides analog machine learning.

Conductivity is controlled by the movement of protons. To increase conductivity, more protons are pushed into the channel in the resistor, and to decrease conductivity, protons are expelled. This is achieved by using an electrolyte (similar to a battery) that produces protons but blocks electrons. Increasing the speed of protons significantly speeds up the process of machine learning.
