Comments on the article

Inkjet cartridges have an unpleasant "feature" of suddenly refusing to work. Making them work again will help soften the hands, which is freely sold in pharmacies.

In the absence of such a liquid in city pharmacies, you can prepare it yourself, observing the following proportions:

glycerin ........................25 g;
ammonia solution 10% ... 25 ml;
ethyl alcohol 95% ..... 25 ml;
purified water............up to 100 ml.

Cartridge cleaning is carried out as follows.

If the cartridge has not worked for a long time, then it is necessary to pump out the existing paint from its cavity with a syringe, but not completely, but leaving it a little. Pour 1-2 ml of the above liquid into the vacant cavity. If you are cleaning a color cartridge, then the cavity where the ink works should not be interfered with. Now wipe the nozzles of the cartridge with a cloth soaked in cleaning fluid. If it has become slightly stained, then the cartridge should be placed with the nozzle down on this cloth and wait 30 - 60 minutes. If the rag began to stain intensively, then consider that the job is done. It remains to pump out the cleaning fluid, pour fresh paint into the cavity and let it stand for one to three hours.

In the case when the cloth does not stain (or stains weakly), you should place the cartridge in an appropriate jar in an upright position, pour cleaning liquid into it to a level above the nozzle by 0,5 cm. Leave the jar for one to three days. After this time, the liquid should begin to color. Then remove the cartridge from the jar and pump out the liquid from it. Pour 1 ml of fresh paint and wipe the nozzles with a damp cloth. The cartridge should work.

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. ... >>

Cold for fast heating 19.02.2020

The fastest way to heat some materials is to cool them first. This idea parallels the Mpemba effect, where hot water sometimes freezes faster than cold water.

To reheat a slice of pizza, you're unlikely to want to chill it first, but a theoretical study suggests that cooling as a first step before heating may be the fastest way to reheat some materials.

The concept is similar to the Mpemba effect, which remains incomprehensible to scientists until now, as it is very difficult to reproduce the effect consistently. The new study is "a way to look at effects like the Mpemba effect from a different perspective," says physicist Andrés Santos of the University of Extremadura in Badajoz, Spain, who was not involved in the study.

Physicists Amit Gal and Oren Raz from the Weizmann Institute of Science in Rehovot, Israel, studied a theoretical system called the Ising model, a two-dimensional grid of atoms whose magnetic poles point up or down. In particular, they considered a variant of the Ising model, in which neighboring atoms point their poles in opposite directions. This behavior is called antiferromagnetic. And this system can heat up faster after the pre-cooling phase.

In order for the new effect to manifest itself, the system must have a corresponding property, other than uniform temperature, which is affected by pre-cooling. Otherwise, there would be no difference between a system that was pre-cooled and warmed up and a system that was just warming up.

In the case of the antiferromagnetic Ising model, the researchers considered the property of the overall magnetization created by all the atoms, as well as how many magnets point in opposite directions. Cooling the material can change the relationship between these two properties so that heating will subsequently occur much faster.
