Salt is one of the few useful and abundant minerals on earth and An essential element in the diet of humans.                                                      -                                           Where do Sea Salt came                          from?                                                                                                                                                                 -                                                   Salt is created in vast beds of sedimentary evaporite minerals that result from the drying up of lakes, seas…Salt is also extracted from some underground beds. The Mediterranean Sea, the Atlantic Ocean, and the North Sea are the most common hubs for the harvesting of sea salt. China is the largest salt producer in the world followed closely by the United States. Salt is generally produced one of three ways: deep-shaft mining, solution mining or solar evaporation.                 -                                                     -               History                                      -                                               Salt was of high value to the Jews, Greeks, the Chinese, Hittites[3] and other peoples of antiquity. Some cultures ascribe magical powers to salt.                                                                -            USES                                              _                                                        It used in cooking, cosmetics and industry. Only 6% of all salt manufactured goes into food. Apparently we use salt in more than 14,000 different ways from the making of products as varied as plastic, paper, glass, polyester, rubber and fertilisers to household bleach, soaps, detergents and dyes.                                                                                                                               -                                            -    BENEFITS                                                                             _                                                        The health benefits of sea salt include good skin care, improved dental health, relief from rheumatoid arthritis, muscle cramps, psoriasis, and osteoarthritis. It also helps in providing relief from acne and rhinosinusitis. Furthermore, it is beneficial for exfoliation, nasal and eye wash…The nutritional compounds of sea salt includes vital minerals like sodium, potassium, calcium, magnesium, bromide, chloride, iron, copper, and zinc among other beneficial elements.                                      -                                             Curiosities and Other facts                                                                    -                                                    Roman soldiers were sometimes paid in salt - which is where the word &#39;salary&#39; comes from.                         -                                                      Every cell in the body contains salt - an adult contains about 250 grammes, equivalent to a  box of Maldon Salt.                                          -                                                         Salt was used to preserve Egyptian mummies</title>

         <description><![CDATA[<div><strong>NATURAL SUBSTANCE</strong><br>The human insulin is a protein that is comprised of 51 amino acids. It is produced by beta cells of the pancreas and plays a key role in regulating carbohydrate and fat metabolism in the body. <br><br>Since the early 1920s, diabetic patients were treated with insulin, which was purified from bovine or porcine pancreas. The development in the field of genetic engineering allowed the production of insulin in <em>E. coli</em> and <em>Saccharomyces cerevisiae</em> (yeast), which have been approved for therapeutic applications in human by FDA.<br><br></div><div>The first licensed drug produced using recombinant DNA technology was human insulin, which was developed by Genentech and licensed as well as marketed by Eli Lilly in 1982.<br><br></div><div>The incidence of diabetes is increasing at an alarming rate and it has been speculated that the number of diabetic patients worldwide would increase to approximately 300 million by the year 2025. Consequently, the requirement for insulin will increase manifold (approximately more than 16000 kg/ year) and the productivity of current insulin expression system would not be sufficient to meet the future market demands. <br><br></div><div>There is an upmost need to increase the production by several fold of a biologically active insulin and its analogues from <em>E. coli</em> and yeast using latest novel and efficient technologies.<br><br></div><div>Another strategy, using a different expression host. Plant-based expression system hold tremendous potential for high-capacity production of insulin in very cost-effective manner. Very high level of expression of biologically active proinsulin in seeds or leaves with long-term stability, offers a low-cost technology for both injectable as well as oral delivery of proinsulin. Moreover, transgenic seeds can also act as warehouse where recombinant insulin can be stockpiled until required.<br><br></div>]]></description>

         <description><![CDATA[<div><strong>ARTIFICIAL SUBSTANCE<br>(</strong>Ángel Almagro Bastida)<br><br>It was isolated in 2004 by two researchers at The University of Manchester, Prof Andre Geim and Prof Kostya Novoselov, who won the Nobel Prize in Physics.<br><br> <strong>Graphene's properties</strong></div><ul><li>The world's first 2D material.&nbsp;</li><li>It is ultra-light yet immensely tough.</li><li>It is 200 times stronger than steel, but it is incredibly flexible.</li><li>It is the thinnest material possible as well as being transparent.</li><li>It is a superb conductor and can act as a perfect barrier - not even helium can pass through it.</li></ul><div><br><strong>Current applications<br></strong><br>Energy:<br>Graphene could dramatically increase the lifespan of a traditional lithium ion battery, meaning devices can be charged more quickly - and hold more power for longer. Batteries could be so flexible and light that they can be stitched into clothing.<br><br>Filtration Membranes:<br>Graphene oxide membranes are capable of forming a perfect barrier when dealing with liquids and gasses. They can effectively separate organic solvent from water and remove water from a gas mixture to an exceptional level. They have even been proved to stop helium, the hardest gas to block.<br><br>Biomedical:<br>Graphene based materials including pristine graphene sheets, few-layer graphene flakes, and graphene oxide offer a variety of unique, versatile and tunable properties that can be creatively utilised for biomedical applications.<br><br>The lateral dimensions of these two dimensional (2D) materials can be adjusted between nanometres and millimetres, and their thickness can be tuned from single to hundreds of monolayers and their flexural rigidity can also be modulated. The flat surface can be easily functionalized enabling modification of the surface property (from hydrophobicity to hydrophilicity) and this is unprecedented among other nanomaterials, offering enormous design capabilities as a platform for drug delivery and ultrasensitive biosensors.<br><br>&nbsp;Sensors:<br>Graphene is an ideal material for sensors. Every atom in graphene is exposed to its environment allowing it to sense changes in its surroundings. For chemical sensors the goal is to be able to detect just one molecule of a potentially dangerous substance. Graphene now allows for the creation of micrometre-size sensors capable of detecting individual events on a molecular level.<br><br>Graphene oxide can be used to create 'smart' food packaging products. This could dramatically cut down on unnecessary food wastage and simultaneously help prevent illnesses. Packaging which has been coated with graphene has the ability to detect atmospheric changes caused by decaying food.<br><br>Electronics:<br><br>Graphene can be used as a coating to improve current touch screens for phones and tablets. It can also be used to make the circuitry for our computers making them incredibly fast. These are just two examples of how graphene can enhance today's devices. Graphene can also spark the next-generation of electronics.<br><br>Graphene could see a smart phone which you could wear on your wrist or a tablet you could roll up like a newspaper. Flexible, wearable electronics take advantage of graphene's mechanical properties as well as its conductivity. Indium-tin oxide is currently used for touch screens as it conducts well but it is brittle.<br><br>Researchers at The University of Manchester have already created the world's smallest transistor using graphene. The smaller the size of the transistor, the better they perform within circuits. The fundamental challenge facing the electronics industry in the next 20 years is the further miniaturisation of technology.<br><br><figure class="attachment attachment-preview" data-trix-attachment="{&quot;contentType&quot;:&quot;image&quot;,&quot;height&quot;:375,&quot;url&quot;:&quot;http://www.graphene.manchester.ac.uk/media/eps/graphene/explore/what-graphene-can-do/chicken-wire-01_500x375.png&quot;,&quot;width&quot;:500}" data-trix-content-type="image"><img src="http://www.graphene.manchester.ac.uk/media/eps/graphene/explore/what-graphene-can-do/chicken-wire-01_500x375.png" width="500" height="375"><figcaption class="caption"></figcaption></figure>Artistic impression of a corrugated graphene sheet</div>]]></description>
