To prepare lead resinate, 1,5 kg of rosin is melted to a liquid state; then add, depending on the intended action, from 60 to 180 g of finely ground lead litharge in small portions with continuous stirring. Stirring is continued until lead oxide is completely combined with rosin. Allow to cool and then pour the mass into molds.

To prepare a desiccant, the required amount of a tar-metal compound is heated with a small amount of turpentine and diluted with turpentine after dissolution to the desired consistency.

According to another recipe, 1,5 kg of rosin, 60 g of ground lead litharge and 20 g of manganese peroxide are taken. Preparation is carried out as described above.

To prepare precipitated lead resinate, take 200 wt. hours of harpius. 30 wt. hours of caustic soda (77%), 320 wt. hours of water and boil until all the resin is washed. Prepare in parallel a solution of 200 wt. hours of acetic lead salt (lead sugar) in 840 wt. hours of water. A soapy solution of harpius is slowly poured into a boiling solution of acetic lead salt. Lead resinate precipitates out, which is ground to a powder upon cooling. The desiccant, obtained by melting, has the appearance of dark pieces, very fragile; the precipitated desiccant occurs as a fine white powder. Manganese driers are more likely to dry out oils than lead driers. Interestingly, a mixture of lead and manganese driers has a much stronger effect on drying oils than either of them separately.

There is a product on sale that is a mixture of manganese and lead resinates. This desiccant is very suitable for drying oils from sunflower oil. Drying oil cooked on lead driers darkens in air (due to the action of hydrogen sulfide).

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 ... >>

Origami helps generate electricity 28.04.2017

Zhong Lin Wang, Chenguo Hu of the Beijing Institute of Nanoenergy and Nanosystems, Chinese Academy of Sciences, as part of a US-China team of scientists, have developed a lightweight paper device inspired by the Chinese and Japanese art of paper cutting, which can collect and store energy from body movements. Scientists described their invention in an article published in the journal ACS Nano.

Despite many advances in the field of portable electronic devices, one thing remains the same: sooner or later you need to plug them into an outlet to charge. meanwhile, devices like watches, heart monitors, and hearing aids often require only a small amount of power. Typically, they get this energy from conventional rechargeable batteries.

But scientists decided to see if they could separate our small energy needs from the outlet and get energy from the movements of the user's body. Wang and others have been working on this approach in recent years, building triboelectric nanogenerators (TENGs) that can harness the mechanical energy around us - like our walking - and then use it to power portable electronics. The problem is that most TENG devices take several hours to charge a small device, like a sensor, and are made of acrylic, which is quite heavy.

So the researchers turned to an ultra-light rhombic paper cut a few inches long and coated it with various materials to turn it into a powertrain. The four outer sides, made of gold- and graphite-coated sandpaper, contained a supercapacitor element for energy storage. The inner surfaces, made of paper and covered with gold and fluorinated ethylene-propylene film, contained the TENG harvester. It is enough to press it for just a few minutes that the device is charged up to 1 volt, which is enough to power the remote control, temperature sensor or clock.
