Where were aluminum spoons valued more than gold ones?

By order of Napoleon III, aluminum cutlery was made, which was served at gala dinners to the emperor and the most honored guests. Other guests at the same time used devices made of traditional precious metals - gold and silver.

Where did tea come from?

It seems amazing when you think that we are still drinking the drinks that man enjoyed thousands of years ago! Tea is one of those drinks.

The Chinese have been appreciating the mild stimulating effects of tea for 4000 years! And the Western world had to wait long enough for them to get to know and love this drink - this is because tea was brought to Europe about 300 years ago. At the beginning of the XNUMXth century, people in Europe and North America began to drink tea. As a result, the tea trade in China flourished. To transport the best varieties of tea to North America and Europe, there were even high-speed ships called "tea clippers".

The British discovered wild tea bushes in the Indian city of Assam. Biologists believe that the Chinese brought the seeds from India and planted them in China, as no wild tea was found there. The British discovered that Indian plants made tea as good as Chinese ones. Gradually large tea plantations were established first in India and then in Ceylon. In Ceylon, tea production became a major industry, and in 1940 Ceylon surpassed China in tea exports.

Tea has also always grown in Java, Sumatra and Formosa.

There are two types of tea trees. In China, they reach 1 meter in height. And Indian trees can reach 6 meters if they are allowed to.

Do you know that the British are among the biggest tea drinkers? The average Englishman drinks about 4 kg of tea per year, while the average American drinks only 0,5 kg of tea in the same time.

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 ... >>

Efficient artificial photosynthesis 18.11.2022

A team of chemists has developed an artificial photosynthesis system many times more efficient than any current solution. It can produce ethanol, methane or other fuel. Through this process, we may soon be fueling cars.

In nature, photosynthesis is carried out by several complex complexes and systems that are difficult to direct to perform other tasks. They take in water and carbon dioxide, break down molecules, and redistribute atoms to make carbohydrates. Over the production of methane instead of them, chemists have been fighting for decades. A group of scientists from the University of Chicago decided to add to the reaction something that is not found in natural photosynthesis - amino acids.

It is based on metal-organic framework structures (MOFs), a class of materials made of metal ions bound by organic molecules. Then a layer was created from it, which became a surface for chemical reactions, and it was immersed in a solution with cobalt. Finally, amino acids were added.

The result showed that both halves of the reaction can be improved in this way: the process of splitting water and the process of combining electrons and protons with carbon dioxide. In both cases, the amino acids increased the efficiency of the reaction by one order of magnitude compared to similar methods.

Artificial photosynthesis has a long way to go before it can produce enough fuel to be relevant for widespread use. However, this is an important step in the right direction. In addition, the discovery can be applied to other chemical reactions, such as pharmaceuticals or the production of nylon.
