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 ... >>

New materials will replace genuine leather 08.07.2016

Platinum Dirt from California, USA works with leather taken from car seats, old sofas and any other items. The result is leather jackets, skirts, bags, as well as various items such as leather leggings and wristlets.

The question is, how to replace the actual leather in cars, if it then has to be disposed of anyway? To the counter question, why change the skin, supporters of "leather replacement" point out that the skin is so widely used in cars that it has lost any "status", and the recently shown prototype of the Rolls-Royce of the future offers silk upholstery. In addition, there is a growing number of vegans in the world - vegans who oppose the exploitation of animals and exclude all animal products from their diet, as well as people who simply sympathize with animals. Accordingly, automotive companies are offering alternative upholstery materials.

For example, well-known artificial leather, which makes you feel cold in winter and sticks to your back in summer, at Toyota has turned into a material called SofTex, which dries faster than leather and surpasses it in terms of durability. And the Sensatec material used in BMW is even treated with a special compound that smells like leather. Sports cars like Lamborghini are experimenting with carbon-fibre fabric, like much of the bodywork. Maserati, like Rolls-Royce, prefers silk seat inserts, and not just any, but from the famous supplier of materials and fashionable clothes Ermenegildo Zegna.

However, the newest and most unexpected word in applied materials science seems to have come from an English startup called Ananas Anam. Using pineapple leaves from the Philippines, the company has learned how to produce artificial suede, not much different from the real one. In addition to fiber for the material, the process produces biomass that can be used as fertilizer.
