What is tin-lead alloy?

First, an alloy is a metal that results from mixing several metals during smelting. The basis of the tin-lead alloy is tin. It is usually mixed with lead in the following proportions: 6 or 4 parts of tin to 1 part of lead. Such an alloy has been produced for thousands of years, although it is difficult to give a more precise date. It is said to have been known to the ancient Chinese, Egyptians and Greeks. The ancient Romans also made it.

Usually the mention of the tin-lead alloy is associated with England, and there is a reason for this. In Cornwall there were mines with deposits of high quality tin. England has been smelting it since ancient times, and tin from Cornwall has been used to make such alloys in other parts of Europe. Tin-lead alloy was used for three main purposes: for the manufacture of church utensils, for domestic use and for public use. Communion bowls made from a pewter-lead alloy have been used in church services in England since the Middle Ages. In England, this alloy began to be widely used for the manufacture of plates and cups.

But over time, the rich began to prefer silverware, and the middle classes used a tin-lead alloy instead of silver.

In France, this alloy has been used to make glasses and goblets, plates, salt shakers and pots since the XNUMXth century.

In Germany, the industrial production of tin-lead alloy arose in the XIV century, and almost at the same time it began to be smelted in Belgium, Holland, Switzerland, Russia and the Scandinavian countries.

In the United States during the early colonial period, it was used more for household purposes. Some items date back to the 1750th century, but the largest amount of alloy was produced between 1850 and 1000, when it was used to make any household utensils. Tin-lead alloy was smelted in China, Korea and Japan more than XNUMX years ago.

Who do the Americans call the Yankees?

Although Americans are called "Yankees" around the world, within the US the term has a more specific meaning. In the 18th century, the nickname Yankee was given to residents of the northeastern states known as New England. And during the Civil War, the southerners began to contemptuously call the Yankees already all the northern soldiers.

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. ... >>

Photonic chips Infinera ePIC-500 and oPIC-100 29.03.2015

Infinera, which recently completed 7400 km PM-8QAM next-generation fiber testing with BICS, this week unveiled two photonic integrated circuits for fiber optic networks based on a new model. This model reflects the changes associated with the growth and virtualization of networks. It includes Layer C and Layer T.

In a world where the number of cloud services and the role of high-speed connections is growing rapidly, service providers need to scale, simplify and make their networks more flexible. A means of solving these problems at the upper levels is Network Function Virtualization (NFV), which allows you to transfer the execution of network functions from specialized hardware to software services running on universal processors in cloud processing centers. Support for NFV and other cloud services is highlighted with Layer C (Cloud). Layer C support requires cloud data centers and consumers to be connected by a highly scalable and flexible Layer T (Transport) transport network.

The ePIC-500 and oPIC-100 chips introduced by Infinera make it possible to "cut" the throughput into portions, dividing it among consumers. The ePIC-500 chip installed in the node has a throughput of 500 Gbps, while the throughput of the oPIC-100 is 100 Gbps. By installing ePIC-500 and oPIC-100 in different parts of a district or city scale network, you can form Layer T.

Infinera has modeled a wide range of applications ranging from city-scale aggregation to regional coverage areas with different topologies including stars, cells and rings. According to them, the use of new photonic integrated circuits allows, on average, to reduce the number of modules by 28%, reduce power consumption by 31% and reduce bandwidth losses by 45% compared to existing serial solutions based on solutions operating at a single wavelength, and WDM solutions at 100, 200 and 400 Gbps.
