How is artificial rubber made?

Natural rubber is made from latex, the milky sap of the rubber tree. Latex is contained in a network of tiny vessels under the tree's bark. When the bark is removed, white milky juice is released. Small pieces of rubber float in this juice. Man has learned to create latex by combining chemicals. Such rubber is called synthetic.

A type of synthetic rubber produced in large quantities is called general purpose rubber. It is produced from two main constituents: butadiene and sterol. Butadiene is a gas derived from petroleum, while sterol is a liquid derived from petroleum and coal. Butadiene and sterol are pumped into large containers containing soapy water.

The soapy solution facilitates the process of forming rubber particles. Catalysts are added, chemicals that speed up a chemical reaction. As the mixture in the container is stirred, it gradually turns into a white, milky liquid. It's synthetic latex.

Synthetic latex is very similar in appearance to natural latex, obtained from the rubber tree. Once the synthetic latex is in the right condition, chemicals are added to stop the reaction. The latex is then pumped into another container with acid and saline. There he curls up. Curled pieces of synthetic rubber look like gray grains. They are washed to remove unwanted chemicals, the synthetic rubber is dried and pressed into pellets.

There are different types of synthetic rubber. They are produced by adding various additional substances or combining them in a special way.

What seafood can cause suffocation while eating them?

Sannakji is a Korean dish made from chopped live octopus seasoned with sesame oil. If served immediately, while the octopus's muscles are still contracting, the pieces on the plate will move. And when eating, you need to be especially careful, because because of this contraction, a piece of octopus can block the air from entering through the throat. Even several lethal cases from suffocation of sannakchi have been recorded.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

ROG Strix GeForce GTX 1080 Ti and Turbo GeForce GTX 1080 Ti graphics cards from Asus 22.03.2017

Asus has unveiled the new Republic of Gamers (ROG) Strix GeForce GTX 1080 Ti and Asus Turbo GeForce GTX 1080 Ti graphics cards based on the Nvidia GeForce GTX 1080 Ti GPU.

The new graphics cards provide a 35% performance increase over GeForce GTX 1080 series graphics cards and outperform Nvidia Titan X series graphics cards. An important feature of ROG Strix GeForce GTX 1080 Ti and Turbo GeForce GTX 1080 Ti is that they support the latest gaming technologies and virtual reality possibilities. The high quality of these graphics cards is guaranteed by the fully automated Auto-Extreme production process. The package of new products includes GPU Tweak II software, which is used to configure and monitor the parameters of the video card.

The ROG Strix GeForce GTX 1080 Ti is 2,5 slots wide for improved heat dissipation. The ROG Strix GeForce GTX 1080 Ti features many Asus-exclusive technologies, including the industry's first MaxContact high-performance cooling system with direct contact technology (heatpipes in direct contact with the GPU surface) and three fans with optimized impeller geometry. Thanks to them, this cooler is able to cool the video card at a low level of load in the passive mode, that is, at zero noise level. The efficiency of this cooling system has increased by 30%, and the noise level has decreased by three times compared to similar models. Partial dust protection of the fans (IP5X) extends the life of the cooling system.

Support for exclusive Asus Aura Sync LED lighting technology will help complement and diversify the look of the ROG Strix GeForce GTX 1080 Ti. The presence of two HDMI ports will allow you to conveniently connect VR kits and immerse yourself in the exciting world of virtual reality without disconnecting the main monitor from the video card.

The Asus Turbo GeForce GTX 1080 Ti is equipped with a dual ball bearing fan that lasts several times longer than traditional sleeve bearing fans. The ability to install a logo will add individuality to the system. The presence of two HDMI ports will allow you to conveniently connect VR kits.

The high quality of ASUS graphics cards is supported by the fully automated Auto-Extreme manufacturing process, which meets more stringent environmental regulations by eliminating harmful chemicals and reducing power consumption by 50%. In addition, since the launch of Auto-Extreme technology-enabled graphics cards, their reliability has increased by 30%.

Modern Asus graphics cards are compatible with the exclusive GPU Tweak II utility, which gives you full control over your computer's graphics subsystem, including advanced overclocking features for overclockers. For example, the new Gaming Booster feature allows you to instantly allocate all available computing resources to a running application to ensure maximum performance.
