Most major automakers are pledging to build millions of electric vehicles as the world’s governments crack down on climate-damaging emissions from traditional-fuel engines. As a result, demand is surging for lithium-ion batteries and the materials needed to make them — including cobalt, a relatively rare substance found mostly in the Democratic Republic of Congo. Sixty per cent of the world’s cobalt comes from the Congo. Congo’s market share may jump to 73 per cent by as producers like Glencore expand mines, according to Wood Mackenzie. By , global demand could be 47 times more than it was last year, Bloomberg New Energy Finance estimates. Few commodity markets are so dominated by one supplier, and that presents a problem for the world’s automakers. Advertisement Cobalt is a byproduct of copper and nickel mining. Until recently, there were often surplus supplies as it was used mostly to harden steel. But the bluish-gray metal’s ability to efficiently conduct electricity has made it essential for high-end rechargeable batteries.

Background color shows metal—metalloid—nonmetal trend in the periodic table Structure and bonding hcp and fcc close-packing of spheres The atoms of metallic substances are typically arranged in one of three common crystal structures , namely body-centered cubic bcc , face-centered cubic fcc , and hexagonal close-packed hcp. In bcc, each atom is positioned at the center of a cube of eight others. In fcc and hcp, each atom is surrounded by twelve others, but the stacking of the layers differs.
Some metals adopt different structures depending on the temperature. This provides the ability of metallic substances to easily transmit heat and electricity. While this flow of electrons occurs, the solid characteristic of the metal is produced by electrostatic interactions between each atom and the electron cloud.

Clock-watch[ edit ] The earliest dated watch known once belonged to Philip Melanchthon and is now in the Walters Art Museum , Baltimore The first timepieces to be worn, made in the 16th century beginning in the German cities of Nuremberg and Augsburg , were transitional in size between clocks and watches. Nuremberg clockmaker Peter Henlein or Henle or Hele is often credited as the inventor of the watch.
He shapes many-wheeled clocks out of small bits of iron, which run and chime the hours without weights for forty hours, whether carried at the breast or in a handbag However, other German clockmakers were creating miniature timepieces during this period, and there is no evidence Henlein was the first. They were heavy drum-shaped cylindrical brass boxes several inches in diameter, engraved and ornamented.
They had only an hour hand. The face was not covered with glass, but usually had a hinged brass cover, often decoratively pierced with grillwork so the time could be read without opening. The movement was made of iron or steel and held together with tapered pins and wedges, until screws began to be used after Many of the movements included striking or alarm mechanisms.
They usually had to be wound twice a day. The shape later evolved into a rounded form; these were later called Nuremberg eggs. Still later in the century there was a trend for unusually-shaped watches, and clock-watches shaped like books, animals, fruit, stars, flowers, insects, crosses, and even skulls Death’s head watches were made. These early clock-watches were not worn to tell the time. The accuracy of their verge and foliot movements was so poor, with errors of perhaps several hours per day, that they were practically useless.
They were made as jewelry and novelties for the nobility , valued for their fine ornamentation, unusual shape, or intriguing mechanism, and accurate timekeeping was of very minor importance.

Anachronisms – A Sure Proof of Fraud Probably ever since mankind began to write, there have been those who have tried to take advantage of the power of the written word by passing off their own writings, which would not have much credence if their true authorship were known, as the writings of someone with more authority, especially some long-dead authority.
January 16, at 3: Long polar winters mean no daylight at all, just one day changes another without any sign of the Sun rising above the horizon. There is only polar night for day a year. But across this Northern coast there was always a short way for the cargo boats to travel from Eastern part of Russia to the Western. Now this trip can be made fairly easy with the appearance of all the satellite navigation equipment like GPS and others, but during the Soviet Era they had none of this.
So, the Communist Party of the Soviet Union decided to build a chain of lighthouses to guide ships finding their way in the dark polar night across uninhabited shores of the Soviet Russian Empire. So it has been done and a series of such lighthouses has been erected. They had to be fully autonomous, because they were situated hundreds and hundreds miles aways from any populated areas. After reviewing different ideas on how to make them work for a years without service and any external power supply, Soviet engineers decided to implement atomic energy to power up those structures.
So, special lightweight small atomic reactors were produced in limited series to be delivered to the Polar Circle lands and to be installed on the lighthouses. It was a kind of robot-lighthouse which counted itself the time of the year and the length of the daylight, turned on its lights when it was needed and sent radio signals to near by ships to warn them on their journey.
My cat used to drink from the garden pond and never seemed to suffer any ill effects, and you often see dogs drinking from muddy puddles. So why do humans have to be so careful and only drink clean water? Will it form sediment that gets buried beneath the seabed and eventually turns into plastic “oil” or “coal”?

Share this article Share When police searched their homes in towns near the historic site, they were able to match the tools they recovered to plaster casts of marks left in the soil. Experts from the British Museum helped to analyse and date the recovered items, which have not been officially valued, and link them to the site. Police took casts of the marks made by Cox and West’s tools at the historic site Cox and West pleaded guilty to two counts of theft from a scheduled monument on December The thieves were also issued with ASBOs preventing them from using metal detecting equipment.
The coins they discovered at the site are similar to the massive haul of 50, Iron Age items found in Jersey last year, the largest hoard of Celtic coins ever unearthed. An inquest is then held to determine if the items should be declared treasure, in which case they must be offered for sale to a museum so they can be preserved for the nation. The proceeds from the sale are then shared between the person who discovered the items and the owner of the land where they were found.
Among the best-known items to have been declared treasure is the Staffordshire Hoard, a collection of 1, Anglo-Saxon items made from gold and other precious metals which was found in Chester Farm is best known as a Roman town, showing evidence of houses, a cemetery and even a temple to the local Romano-Celtic gods. It also contains remains of an earlier Iron Age settlement, and was later the site of a mediaeval village.

It is a completely enclosed suit of combat armour composed of shaped Adamantium and Plasteel plates, encased in a Ceramite ablative layer. Each suit possesses a full suite of life-support functions for operation in hostile environments, an automated medicae system to provide some level of first aid to a wounded wearer and a highly advanced and fully integrated tactical targeting and threat analysis system known as Auto-senses.
The suit would be heavy and cumbersome to wear but for the electrically-motivated fibre bundles within the armour that replicates the wearer’s movement and enhances his strength beyond its already considerable superhuman baseline for Space Marines. Whilst Power Armour is most commonly associated with the Space Marines of the Adeptus Astartes , the Sisters of Battle and many Inquisitors also use powered armour of one sort or another.
Typically, however, these armours may not contain the same strength-enhancing properties or life-support functions of Space Marine Power Armour, nor do they always provide the same level of protection. Contents Design Schematics of Mark VI Corvus Pattern Power Armour The enclosing suits of armour worn by Space Marines are made from thick ceramite plates and would be cumbersome but for electrically motivated fibre bundles that replicate the movements of the wearer and supplement his strength.
The last gene-seed organ to be implanted in a Space Marine — the Black Carapace — rests beneath the skin, itself fitted with neural sensors and transfusion ports. These plug-in points mesh with Space Marine Power Armour, linking the wearer’s nervous system to his suit’s mind impulse controls, turning the suit into a second skin that moves with all the speed and precision of the Battle-Brother’s own body.
There are several patterns or “marks” of Power Armour, whose appearances differ significantly.

Gallium crystals Metals are shiny and lustrous , at least when freshly prepared, polished, or fractured. Sheets of metal thicker than a few micrometres appear opaque, but gold leaf transmits green light. The solid or liquid state of metals largely originates in the capacity of the metal atoms involved to readily lose their outer shell electrons. The electrons involved become delocalised and the atomic structure of a metal can effectively be visualised as a collection of atoms embedded in a cloud of relatively mobile electrons.
This type of interaction is called a metallic bond. Magnesium, aluminium and titanium are light metals of significant commercial importance. Their respective densities of 1.

The history of watches began in 16th century Europe, where watches evolved from portable spring-driven clocks, which first appeared in the 15th century. The watch which developed from the 16th century to the mid 20th century was a mechanical device, powered by winding a mainspring which turned gears and then moved the hands, and kept time with a rotating balance wheel.
