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 ... >>

Electricity from mushrooms and wooden floor 01.04.2021

Wood consists of fibers of cellulose and hemicellulose polymers in a lignin matrix. Cellulose in the composition of wood can be amorphous and crystalline. The presence of the latter makes wood a piezoelectric material - a material in which electric charges arise under the action of deformation. When cellulose crystallites are compressed, the centers of gravity of positive and negative charges diverge in space, and charges arise on the surface of the crystallite to maintain electrostatic equilibrium. The piezoelectric properties of wood have been known since the fifties, but no one has made commercial materials and devices for generating electricity from it - due to the low piezoelectric modulus and the deformability of wood, this was considered unprofitable.

Swiss scientists led by Ingo Burgert from ETH Zurich managed to enhance the piezoelectric properties of wood. Burgert and his colleagues have long been able to change the properties of wood and obtain various functional materials on its basis. For example, last year they turned balsa wood into a luminous material by dissolving lignin and replacing it with a solution of luminescent quantum dots. To make wood a good piezoelectric, you also need to dissolve the lignin, then the wood will become looser, and it will be easier to deform it. In order to carry out the dissolution gently, without damaging the cellulose framework, Burgert and his colleagues proposed an unexpected solution - they treated the wood with mushrooms from the basidiomycete department.

The scientists again took the light wood of the balsa tree (Ochroma pyramidale) with a density of 94,8 kilograms per cubic meter as the basis for the material. Three types of fungi were used to dissolve lignin: Phanerochaete chrysosporium, Ganoderma adspersum, and Ganoderma applanatum. The wood was cut into thin plates, dried at a temperature of 100 degrees during the day, a freshly prepared mushroom culture was applied to the surface and left in a humid atmosphere for a period of 4 to 12 weeks.

To control how much lignin the fungi had time to absorb, wood samples were thoroughly cleaned and dried again for a day, and then weighed. The fastest loss of lignin was provided by the fungi Ganoderma applanatum. The optimal processing time Burgert and his colleagues considered eight weeks (corresponding to a weight loss of 45 percent mainly due to lignin) - with longer processing, the wood became too loose and significantly lost strength. Fourier IR spectroscopy confirmed that the fungi preferentially absorbed lignin, and a slight loss of hemicellulose was also observed. But the cellulose frame of wood remained practically unchanged after treatment - this was clearly visible not only in the IR spectra, but also in the images of scanning electron microscopy.

Lignin-free wood had better compressibility. As a result, the displacement of the centers of gravity of the charge in cellulose crystallites occurred with a greater amplitude, and the piezoelectric effect also increased. A cube of treated wood measuring 15 x 15 x 13,2 millimeters generated a voltage of 0,87 volts and a current of 13,3 nanoamps. This is fifty-five times more than unmodified wood under the same conditions. By connecting nine such cubes in series, the authors obtained electricity sufficient to power a light emitting diode.

From the new material, the authors propose to make a floor covering that will produce electricity under the weight of human steps. Such a coating could be placed in the homes of the elderly and powered by sensors that are activated if a person falls. There are more exotic ideas for using piezoelectric wood floors in dance and aerobics rooms. Note that so far Burgert and his colleagues have obtained a piezoelectric material only from balsa wood - light and with a large number of pores. In the future, they are going to adapt the method for denser and heavier types of wood.
