Here are some recipes dyeing sheepskins and skins with acid dyes.

Dye bath is compiled as follows:

Dye 2 wt. hours;
Sulfuric acid 1 wt. hours;
Glauber's salt 8 wt. h.

Formic acid is added to the bath in an amount of 25 to 50 g for each pair of skins, depending on the intensity of color that you want to get.

red tone

All durable paints are applicable. Good results are obtained by using 25 g of strong acid paint and 25 g of azofuxine.

3 golden brown tone

Acid brown paint 6 wt. hours;
Naphthylamine black 1 wt. h.

Electric blue tone

For each pair of skins take 25 g of alkali blue and 50 g of crystal soda; after half an hour, the skins are removed and, for the manifestation of color, they are processed with a cold solution of copper sulphate. When using a warm solution, a reddish tint is obtained.

Silver gray tone

Equal parts of silver gray paint and acetic acid.

brown tone

Brown acid paint 12 wt. hours;
Acid green 2 wt. hours;
Naphthol greens 3 wt. h.

Developed in a weak solution of copper sulphate.

Picric acid gives good tones when mixed with other appropriate acid dyes, such as light blue, brilliant green, scarlet, gold, etc.

A very common method is pre-staining with dye plant extracts. For example, for a bronze-green tone, the skins go first into a bath of turmeric extract with the addition of alum, and when a light yellow shade is obtained, methylene green and Bismarck brown are added to the bath. Dyeing is continued until the desired shade is obtained.

After dyeing, the skins are washed with warm water, refinished and dried.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Nanosilicon in the fight against infections 08.07.2012

Scientists at Brown University have found that a coating of silicon nanoparticles can effectively combat the spread of staphylococcus bacteria. This discovery will allow the creation of low-cost coatings for medical equipment, implants, hospital equipment and household appliances. This is essential to fight infections - especially antibiotic-resistant superstrains of bacteria that often even cause hospitals to be demolished.

Silicon is an inexpensive common substance that is present in our body. It has long been known that it is able to fight bacteria, but so far it has not been possible to create a silicon coating.

Scientists at Brown University have used silicon nanoparticles for the first time to coat a polycarbonate catheter and endotracheal tube. As a result, the number of staphylococcus bacteria on these medical supplies has been reduced by 90%.

The main task in creating an antibacterial coating is to prevent the formation of a biofilm that unites a colony of bacteria and makes it very resistant to environmental influences. The silicon coating prevents biofilm formation and makes it easier for the patient's immune system to clean the implant. At the same time, silicon is much cheaper than silver and does not harm human immunity.

Scientists have grown silicon nanoparticles of two different sizes and made four types of coating with different concentrations of both types of particles. All types of coatings have proven effective and reduced the number of staph in 24, 48 and 72 hours. The coating with the smallest particles had the most powerful effect: after a day, the number of bacteria was reduced by 90%. In the near future, scientists plan to start testing implants with a new coating on animals.
