Burnishing of iron and steelwhich aims, on the one hand, to give the surfaces of these metals a beautiful appearance, and on the other hand, to protect them from rust, consists, as you know, in the fact that the metal surfaces, carefully ground and cleaned of grease and dirt, are rubbed with various mixtures of appropriately selected substances and then subjected to high temperatures.

Here are some of the most practical and fast-acting bluing compounds.

1st recipe:

1 part silver nitrate (lapis);
500 parts of water.

2st recipe:

1 part antimony chloride; 1 part olive oil.

3st recipe:

54 parts of copper sulfate;
3 parts iron filings;
14 parts of nitric acid (strong vodka);
26 parts of alcohol;
200 parts of water.

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 ... >>

Nanobots to be launched into human veins 30.07.2016

Researchers at Drexel University have demonstrated how an electromagnetic field can be used to make tiny robots move faster in a liquid medium. Scientists plan to use these devices in the future to deliver drugs through blood vessels.

Nanobots are chains of tiny round particles. The magnetic field rotates the particles, like a screw, while the longer the chain, the greater the speed it can develop. The scientists tested various robots, starting with strings of three "beads". The longest device consisted of 13 particles and reached a speed of 17,85 micrometers per second.

In order for the robots to move, an external magnetic field was applied. The faster the rotation speed of the field, the faster the chains moved. At the same time, the high frequency led to the division of long devices into shorter ones. So, a robot of seven beads, upon reaching a certain speed, begins to deform and is divided into two chains of three and four particles. The direction of the magnetic forces can be changed so that the two robots move in opposite directions.

The chains can be modified to serve as a drug delivery system as well as perform various tasks during surgical procedures. For example, robots can clean veins and arteries blocked by clotted blood cells or cholesterol plaques.
