Sometimes it serves as a solvent for resins gasoline or benzene. Asphalt, dammar, mastic and copal are highly soluble in benzene. A solution of asphalt in benzene is often used to make metal varnishes.

Cheap leather varnishes are made by dissolving black resin in benzene. Sometimes turpentine or alcohol is added to such varnishes.

Durable fast drying benzene varnish

Benzene 10 kg;
Rosin 4 kg;
Coal tar pitch 9 kg.

Coarsely ground rosin is dissolved in benzene in a water bath with low heat (benzene is highly flammable - handle it carefully!). Crushed coal tar pitch is added to the resulting solution with slow heating. After an hour of stirring, the solution is cooled by lowering the boiler into cold water. The finished varnish is allowed to settle, after which the clear solution is drained from the settled sediment and poured into jars.

Asphalt varnish for metal coating

Asphalt 25 kg;
Gasoline 50 kg.

Dissolve the asphalt in gasoline in a water bath with low heating, mix well and allow to settle. When the finished varnish is well settled, it is poured into jars. The varnish is applied in a thin layer, which, when rubbed, gives a brilliant cover.

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 ... >>

Print meat in space 26.08.2019

3D Bioprinting Solutions will send rabbit and cow meat cells into space in September and try to print a steak out of them. This technology is needed to feed astronauts in orbit during very long flights.

The launch of an experiment in space to print meat is scheduled for the ISS on September 25. In September, cells obtained from the gums of a rabbit will be delivered to orbit, as well as cow cells, from which they will try to print meat. Now these cells are undergoing pre-flight tests.

Space-printed meat is much more expensive than regular meat. A kilogram of specially grown cells, from which a conditional steak is printed on a bioprinter, cost more than 2011 million pounds back in 1, excluding the cost of printing. Now the price of a printed kilogram of meat is about $10.

If on Earth no one needs a kilogram of meat for that kind of money, then for space it is cheap. Delivering food to astronauts into orbit is very expensive. Most of the cargo of spacecraft is food, and lifting one kilogram of cargo into orbit costs an average of $40-50 thousand.
