To prepare gold lacquer for tinplate, grind 40 g of crystalline copper acetate in a porcelain mortar into a fine powder and, pouring a thin layer on a shallow plate, place it in a warm place for a while. When the powder acquires a light brown color, it is ground in a mortar with turpentine and 120 g of fatty copal varnish heated to 70 ° C is added, with constant stirring. During this operation, a significant part of the acetic acid salt is dissolved within 15 minutes, after which the varnish is poured into a bottle and stored for several days in a warm place, shaking from time to time.

The varnish prepared in this way is evenly applied to the sheet, which is then dried in an oven.

According to the degree of heating, this or that color is obtained on the tin - first greenish, which, with more significant heating, turns into dark yellow gold, then into orange and, finally, into a reddish-brown color.

Coloring with said lacquer has significant advantages over the commonly used English gold lacquer. Firstly, it surpasses it in brilliance, and secondly, in contrast to English varnish, it does not change at all from the action of daylight. In addition, if the copal lacquer was of good quality, the varnishing of the tin with the new lacquer is so strong that the tin can be bent into any shape without fear of damaging the coating.

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 ... >>

Increasing the rate of photosynthesis 07.09.2018

The ability to recreate the process of photosynthesis in the laboratory is a very tasty morsel for scientists and researchers in the context of modern biological science - if only because it could solve a number of problems associated with the ability to grow something outside of our planet. So researchers from the University of Cambridge have been working on such a project for a long time - and today they presented its first results, which are very promising. And the thing is that they managed to significantly increase the efficiency of natural photosynthesis using a mechanism that had been dormant in plants for a long time.

We are talking about increasing the efficiency of natural photosynthesis of plants through the use of a special photoelectrochemical cell of artificial origin, which is attached to the plant photosystem, which consumes the red and blue spectrum of light. Moreover, this attachment is carried out with the help of a special enzyme called hydrogenase, first found in algae, which have the ability to photosynthesis.

This combination makes it possible to significantly increase the efficiency of the latent evolutionary mechanism of natural photosynthesis in plants, while avoiding the use of any kind of catalyst of electrical origin. For example, early work in one way or another concerned the possibility and necessity of using electricity to enhance photosynthetic properties - however, this approach has a number of very noticeable limitations and does not solve the problem of growing plants outside their natural habitat - that is, outside our home planet.

The results of specialists are very promising in view of the fact that in this way a significant loss of time and the need to use third-party catalysts can be avoided. Many are sure that the technology and method presented by these specialists will become a part of practice in a certain future and may become one of the conditions for the possibility of flying to other planets and colonizing them. After all, the ability to seamlessly grow plants is worth a lot!
