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 ... >>

Food sensors based on paper and graphene 03.11.2022

Korean scientists have developed new food freshness and temperature sensors. They are based on laser-induced graphene on environmentally friendly, biodegradable paper.

According to data from last year, about 78 percent of the plastic entering the environment is food packaging. Thus, the development of biodegradable bags, boxes and glasses for our food is the primary concern of people who are not indifferent to the problem of plastic pollution of the planet.

Although several large companies have already released their lines of biodegradable packaging, including utensils and drinking straws, there is still the problem of monitoring the quality of food in such packages, that is, tracking the temperature and freshness of food. Most of today's food condition sensors are not biosoluble, so even when attached to eco-friendly packaging, they eventually become part of the plastic that pollutes the planet.

However, now specialists from Seoul National University (South Korea) have found a way to solve this problem by developing a completely biodegradable food quality control sensor based on laser-induced graphene. This sensor is able to monitor the temperature and freshness of food (it captures gases emanating from it), so that using a mobile application, anyone can assess the quality of meat products or the temperature of a cup of coffee.

To obtain sensors, the research team has developed a technology for the synthesis of graphene through a local thermal reaction by laser irradiation of an environmentally friendly carbon-based paper substrate. As a result, the sensor was fabricated directly on a food-grade cellulose substrate, without additional processing that would compromise the packaging's environmental friendliness.

The researchers hope that the sensors they have developed will further reduce the plastic pollution of the planet and make it easier for people who buy food in paper packages to control food quality. In the future, such sensors can be used not only in the food industry, but also in any other industry where environmentally friendly temperature and gas sensors are required.
