What is a sink?

Can you imagine how many different types of coatings exist to protect living organisms? Nut shells, egg shells, tortoise and crab shells, snail shells.

A shell is a hard shell covering something living. It was made either by its owner himself or by his parents. The shell consists of a certain formation. Walnut shells are from woody matter, other shells are from calcium carbonate (lime). Still others are made of quartz, a kind of glass material.

The shell protects the life hidden in it. Nuts and eggs are not permanently coated. The inner living part - the seed or chick - must grow and crack open the shell to come out.

Crabs and crayfish are not always completely surrounded by their shell. It is made of individual plates held together by a soft substance. This allows the animal to move and bend.

Some creatures, such as beetles, grow inside their hard shells as long as they fit inside. Then it splits, and the insect crawls out. Beneath it is soft and stretchy skin. After a certain time, it hardens and turns into a new shell.

And there are creatures in which the shell is part of the body. Turtle shell is a bone covered with special plates. From above, it consists of her ribs and spine, from below, too, from bone. A turtle cannot live without a shell, just like a person without a backbone and ribs.

A large group of living creatures that have a shell are molluscs. Snails are one of the varieties of this group. Oysters, Hungarians, scallops and many others are bivalves. When threatened, they can completely slam their shells shut.

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 ... >>

CoolSiC 1200V Silicon Carbide MOSFETs in TO247-3/-4 Package 16.01.2020

Infineon's new 1200V CoolSiC MOSFETs in the TO247-3/-4 package are based on state-of-the-art semiconductor technologies and optimized for high performance and reliability.

The advantage of using SiC transistors compared to Si solutions is higher efficiency, which is especially important for power conversion systems. Compared to Si-based IGBTs and MOSFETs, SiC MOSFETs have several advantages: the lowest gate charge and capacitance levels among 1200V switches, no internal diode recovery loss, low temperature-independent switching loss, and no-threshold characteristic.

CoolSiC MOSFETs are great for hard and resonant switched topologies such as power factor correction (PFC) circuits, bi-directional topologies, DC/DC converters or DC/AC inverters.

Features:

Low switching losses;
Non-threshold characteristic;
Wide gate-source voltage range;
Gate threshold voltage VGS(th) = 4,5V;
Controlled voltage slew rate (dV/dT);
Robust current-carrying diode for hard switching;
Switching losses are independent of temperature;
Maintaining operability in the event of a short circuit for 3 μs at a gate voltage of 15 V.
Available for order in TO247-4 packages. This package has an additional source signal pin to optimize the switching process.

Application:

Solar energy conversion systems;
Electric vehicle charging systems;
Uninterruptible power supplies (UPS);
Power supplies;
Engine management.
