What are detergents?

Detergents are substances that make things clean. Soap is one of the types of detergents. But when we say "soap", we mean a cleaning agent made from natural materials. And when we say "detergent", we mean a substance made from synthetic materials. Synthetic detergents are made by combining various chemicals in a complex manufacturing process. Petroleum products, fats, resins and other components are part of the complex composition of these substances. They are produced in chemical plants with special equipment.

Those components of detergents that have a real cleaning effect are called surfactants, abbreviated as surfactants. They can be made from a variety of raw materials, such as petroleum products, animal and vegetable fats.

The chemical processes involved in production are very complex. For example, animal fats can be processed with various chemicals: alcohol, liquid hydrogen, sulfuric acid, alkalis - to make only one type of surfactant. The surfactant should be mixed with other chemicals that help remove dirt more thoroughly and prevent it from settling back on things that are washed or laundered.

Special bleaches, dyes and foaming agents may also be added. Synthetic detergents have become so popular because they can lather in any type of water - soft or hard, cold or hot. In this case, there is no sediment that remains on the walls of the bath. Most of the products we use in dishwashing and laundry are synthetic detergents. Soap is basically a personal hygiene item.

 Random interesting fact from the Great Encyclopedia:

Which insect males steal wedding gifts from other males by mimicking a female?

One of the species of scorpion flies, Hylobittacus apicalis, has been described as entertaining mating relationship. For mating, the male must necessarily present prey to the female as a gift, and the larger the prey, the higher the likelihood of mating. The female eats prey in the process, and if there is still not very much food, mating is completed before the moment of insemination. Males sometimes do not get prey on their own, but steal it from mating pairs. Some males act even more subtly - when they see another male with prey, they fly up to him and make movements typical for a female before mating, often receiving a "wedding gift" and flying away with him to look for their female.

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 ... >>

Qualcomm Snapdragon 602A Processor for Automotive Media Centers 13.01.2014

Qualcomm introduced several new processors at CES 2014. One of them was the 4-core Snapdragon 802 chip, designed for TVs with a 4K screen resolution. Another single-chip system, which will be discussed, was designated Snapdragon 602A.

This processor is designed for use in automotive infotainment systems. The product, according to the developer, fully complies with the AEC-Q100 standard, which means stringent requirements for operating temperature, quality, reliability and durability.

The Snapdragon 602A includes four Krait processing cores (clock frequency not specified) and an Adreno 320 graphics accelerator. In addition, the chip includes a Hexagon DSP digital signal processor, a GNSS module to support satellite navigation, as well as audio and video information processing units.

The Snapdragon 602A includes an integrated Qualcomm Gobi 9x15 multi-modem for connecting to third and fourth generation (LTE) mobile networks. Plus, the platform provides support for Dual-Band Wi-Fi 802.11ac (2,4 and 5 GHz) and Bluetooth 4.0 Low Energy (LE).

Qualcomm emphasizes that the Snapdragon 602A enables next-generation in-car multimedia systems with 3D navigation, facial recognition, gestures and voice commands, support for high-quality sound and XNUMXD games for passengers in the back row of seats. Multiple high resolution displays and cameras can be connected. Various operating systems are supported.

Trial shipments of the processor will begin in the current quarter.
