Stainless steel’s strength, resistance to corrosion and low maintenance make it the ideal material for a wide range of applications. There are over grades of stainless steel, of which 15 are commonly used in everyday applications. Due to its strength, flexibility and. There is no other metal that can compare to Aluminum when it comes to its variety of uses. Here are the most common uses of Aluminum. Common Uses. Antibiotics Most sore throats are caused by viruses. If your sore throat is caused by a bacterial infection, the most common cause is Group A .
Uses Most Common
Most is used to manufacture steel, used in civil engineering reinforced concrete, girders etc and in manufacturing. There are many different types of steel with different properties and uses. Ordinary carbon steel is an alloy of iron with carbon from 0. Alloy steels are carbon steels with other additives such as nickel, chromium, vanadium, tungsten and manganese. These are stronger and tougher than carbon steels and have a huge variety of applications including bridges, electricity pylons, bicycle chains, cutting tools and rifle barrels.
Stainless steel is very resistant to corrosion. It contains at least Other metals such as nickel, molybdenum, titanium and copper are added to enhance its strength and workability. It is used in architecture, bearings, cutlery, surgical instruments and jewellery. It is used for pipes, valves and pumps. It is not as tough as steel but it is cheaper.
Magnets can be made of iron and its alloys and compounds. Iron catalysts are used in the Haber process for producing ammonia, and in the Fischer—Tropsch process for converting syngas hydrogen and carbon monoxide into liquid fuels. Iron is an essential element for all forms of life and is non-toxic. The average human contains about 4 grams of iron. A lot of this is in haemoglobin, in the blood. Haemoglobin carries oxygen from our lungs to the cells, where it is needed for tissue respiration.
Humans need 10—18 milligrams of iron each day. A lack of iron will cause anaemia to develop. The core of the Earth is thought to be largely composed of iron with nickel and sulfur. The most common iron-containing ore is haematite, but iron is found widely distributed in other minerals such as magnetite and taconite.
Commercially, iron is produced in a blast furnace by heating haematite or magnetite with coke carbon and limestone calcium carbonate. Help text not available for this section currently. Elements and Periodic Table History. Iron objects have been found in Egypt dating from around BC.
They contain about 7. The Iron Age had begun. Some kinds of iron were clearly superior to others depending on its carbon content, although this was not appreciated. Some iron ore contained vanadium producing so-called Damascene steel, ideal for swords. This explained how steel, wrought iron, and cast iron, were to be distinguished by the amount of charcoal carbon they contained.
The Industrial Revolution which began that same century relied extensively on this metal.

Hello, this week we turn to one of the most important elements in the human body. It's the one that makes metabolism possible and don't we just know it. There are iron man challenges, iron fisted leaders and those said to have iron in the soul. But there's a dark side to element number 26 too because its powerful chemistry means that it's also bad news for brain cells as Nobel Laureate Kary Mullis explains. For the human brain, iron is essential yet deadly.
This change from the relatively plentiful and soluble FeII, took a heavy toil on almost everything alive at the time. Surviving terrestrial and ocean-dwelling microbes developed soluble siderophore molecules to regain access to this plentiful, but otherwise inaccessible essential resource, which used hydroxamate or catechol chelating groups to bring the FeIII back into solution.
Eventually higher organisms including animals, evolved. And animals used the energy of oxygen recombining with the hydrocarbons and carbohydrates in plant life to enable motion. Iron was essential to this process.
But no animal, however, has been able to adequately deal, in the long run - meaning eighty year life spans - with the fact that iron is essential for the conversion of solar energy to movement, but is virtually insoluble in water at neutral pH, and, even worse, is toxic. Systems have evolved to maintain iron in specific useful and safe configurations - enzymes which utilize its catalytic powers, or transferrins and haemosiderins, which move it around and store it.
But these are not perfect. Sometimes iron atoms are misplaced, and there are no known systems to recapture iron that has precipitated inside of a cell.
In some tissues, cells overloaded with iron can be recycled or destroyed - but this doesn't work for neurons. Neurons sprout thousands of processes during their existence - reaching out to form networks of connections to other neurons. During development of the adult human brain a large percentage of cells are completely eliminated, and some new ones are added.
It is a learning process. But once an area of the brain is up and running, there is nothing that can be done biologically, if a large number of its cells stop working for any reason.
And the slow creep of precipitating iron over many decades is perhaps most often that reason. In less sophisticated tissues, like the liver, new stem cells can be activated, but in the brain, trained, structurally complex, interconnected neurons are needed, with thousands of projections that are accumulated over a lifetime of learning.
So the result is slowly progressive neurodegenerative disease, like Parkinson's and Alzheimer's. This same basic mechanism can result in a variety of diseases. There are twenty or thirty proteins that that deal with iron in the brain - holding iron and passing it from place to place. Every new individual endowed with a new set of chromosomes is endowed with a new set of these proteins.
Some combinations will be better than others and some will be dangerous individually and collectively. A mutation in a gene that codes for one of these proteins could disrupt its function - allowing iron atoms to become lost. These atoms that have been lost from the chemical groups that hold them will not always be safely returned to some structure like transferrin or haemoferritin. Some of them will react with water and be lost forever.
Only they aren't really lost. They are piling up in the unlucky cell types that were the designated locations for expression of the most iron-leaky proteins. And oxides of iron are not just taking up critical space. Iron is very reactive. The infamous "Reactive Oxygen Species" which have been suspected of causing so many age related illnesses may just derive from various forms of iron. It is time for specialists trained in chemistry, and with an eye to the chemistry of iron, to pay some attention to neurodegenerative disease.
Kary Mullis telling the story of iron, the element that we can't do without, but which at the same time could hold the key to our neurological downfall. Next time on Chemistry in its Element Johnny Ball will tell the story of Marie Curie and the element that she discovered and then named after her homeland. Pitchblende, a uranium bearing ore, seemed to be far too radio active than could be accounted for by the uranium. They sieved and sorted by hand ounce by ounce through tons of pitchblende in a drafty, freezing shed, before eventually tiny amounts of polonium were discovered.
So be radioactive or at least podcast proactive and join us for the mysterious story of Polonium on next week's Chemistry in its Element. I'm Chris Smith, thank you for listening, see you next time. Properties and changes of materials: Reaction between aluminium and iodine.

Though some tests can help you learn more about your heritage and your relatives, other tests let you know more about your general health and your outlook for the future.
Also called presymptomatic genetic testing, this type of test can let you know if you have any of the genes associated with a specific medical condition. A genetic test can reveal whether you have the gene for this disease and whether you have a risk of suffering from the condition later in life.
Genetic testing can also identify genes associated with other diseases. If you are a carrier for a specific disease, you have a chance of passing that gene on to your future children.
The chance of passing on those genes or a child suffering from that condition will increase if both parents are carriers. Your results may determine whether you have biological children or whether you adopt. One of the uses for genetic testing among law enforcement is forensic testing.
Forensic testing allows police officers to identify criminals who committed crimes. When a woman files a police report and claims a man raped her, she will have a rape test done in the hospital. That test will take samples of any sperm, hair or other genetic materials found on her body. Laboratory workers can then compare those samples to suspected criminals to identify the person responsible for the crime.
Law enforcement can also use forensic genetic testing in assault and murder cases. Several companies now offer genealogy testing.
