  • Elemental Business: Vanadium

    28/07/2014 Duración: 28min

    Vanadium, and obscure metal, provides the latest installment in our journey through the economics of the periodic table. This element has hardened steel since ancient times, and today it lies at the heart giant batteries that could be vital to the future of solar energy. Our regular chemistry maestro, professor Andrea Sella of University College London, demonstrates vanadium's surprisingly colourful properties.And, Justin Rowlatt meets Bill Radvak, chief executive of American Vanadium - the only vanadium company in the US - and asks what a 'redox flow battery' could do for the BBC's headquarters in London. We also hear from solar energy entrepreneur Alexander Voigt about the particular niche that vanadium will fill in the future ecosystem of electricity grid storage.

  • Elemental Business: Nitrogen Fertiliser

    27/07/2014 Duración: 33min

    Nitrogen-based fertilisers have banished hunger in the rich world and ushered in an era of abundance. But they are a double-edged sword - the glut of food also comes with a glut of nitrogenous pollution that threatens to destroy our rivers and oceans. In our latest programme about the elements of the periodic table, Professor Andrea Sella of University College London tells presenter Justin Rowlatt why exactly our crops - and we humans - could not survive without nitrogen.The BBC's Washington correspondent Rajini Vaidyanathan sees - and smells - first-hand the denitrification of raw sewage, and hears from water scientist Dr Beth McGee of the Chesapeake Bay Foundation about the eutrophication of America's largest river estuary.And, Justin travels to Norwich to meet Giles Oldroyd of the John Innes Centre, who is seeking to genetically engineer cereal crops that can fix nitrogen from the air. He also meets farmer David Hill, who explains the hi-tech lengths he goes to in order to squeeze the maximum yield out of

  • Elemental Business: Nitrogen Explosives

    26/07/2014 Duración: 35min

    Nitrogen - the world's most abundant gas - has brought life and death to humanity on an epic scale - and tragedy to the scientists that have harnessed its power. It is seemingly inert, yet it can also blow things up. In the first of two programmes on nitrogen, chemistry guru Andrea Sella of University College London explains to Justin Rowlatt how the forces that make this gas so stable are the same ones that make nitrogen compounds such as nitroglycerin so explosive.Jez Smith, former head of research at the world's biggest explosives firm, Orica, talks about the shocking accuracy of modern mining detonations - all of them based on nitrogen.And Justin travels to the headquarters of German chemicals giant BASF to learn about ammonia production from Dr Michael Mauss and Bernard Geis, and how the work of chemists Fritz Haber and Karl Bosch a century ago saved the planet from starvation.

  • Elemental Business: Carbon Plastic

    25/07/2014 Duración: 34min

    Plastics are one of the most useful substances known to man, strong, durable and abundant, but once in the environment, they are here to stay. Professor Andrea Sella tells us about the unique properties of carbon-based plastics - why they are so useful and why they are so hard to get rid of. And, Dr Susan Mossman, a materials science specialist at the Science Museum, gives us a plastics history lesson which has a few surprises along the way. But what happens when the high cost of hydro-carbons make plastics too expensive? Head of the National Non-Food Crops Centre in York, Dr Jeremy Tomkinson, is amongst those out there looking for alternatives. He tells us what a new generation of plastics might have to offer.

  • Elemental Business: Lithium (long version)

    22/07/2014 Duración: 32min

    Lithium is the electro-chemical element - big in batteries and bipolar disorder. Over two decades it has shot from obscurity to become almost synonymous with the way we power our gadgets. Presenter Justin Rowlatt hears from chemistry powerhouse Prof Andrea Sella of University College London about what makes lithium so light and energetic. We hear from Gideon Long in Chile, who visits the world's richest source of lithium in the Atacama Desert, and about how neighbouring Bolivia believes it will dominate supply if demand for this alkali metal continues to see double-digit growth. Justin speaks to Prof Nigel Brandon of Imperial College, an expert on cutting-edge battery research, about whether this week's element can ever realistically hope to challenge a can of petrol as the best way to power a car. And we hear from clinical psychologist Kay Redfield Jamison of Johns Hopkins University about the literally life-saving role lithium has played for sufferers of bipolar disorder - including herself.

  • Elemental Business: Rare Earths

    21/07/2014 Duración: 32min

    The rare earth elements are the focus of the latest instalment in Business Daily's exploration of the real basis of the world economy - the basic building blocks of everything in the universe, the chemical elements.And it's not a short list we cover: Lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, turbium, dysprosium, holmium, erbium, thulium, ytturbium and lutetium. You may not have heard of most of them but some have insinuated themselves deep into modern life. We'll be finding out the extraordinarily range of uses to which they've been put, as well as the big problem: The supply of these is overwhelmingly dominated by China.We'll be hearing from Professor Andrea Sella of University College London, Jack Lifton of Technology Metals Research, the journalist Cecile Bontron who provides a first-hand account of the Chinese processing plant at Baotou, as well as Henrik Stiesdahl and Rasmus Windfeld of Siemens' wind turbine division.

  • Elemental Business: Carbon Diamonds

    20/07/2014 Duración: 31min

    Synthetic or natural? Diamond ring hunters may soon be asking themselves this question, as technological advances mean the gemstone market could be poised for a flood of man-made stones. Presenter Justin Rowlatt visits the new research headquarters of Element Six, the synthetics arm of mining giant de Beers, to find out how they are made and their proliferating industrial uses. He hears from diamonds journalist Chaim Even Zohar about the factory-made diamonds fraudulently passed of as natural gems. Author Matthew Hart retells the yarn of how a lowly small-time prospector first broke the de Beers cartel. And we hear from de Beers itself - their marketing head Stephen Lussier explains why diamonds really are forever.

  • Elemental Business: Carbon Materials

    17/07/2014 Duración: 27min

    We take a second look at carbon, one of the most versatile of all the elements, in the latest episode of our series looking at the economy of the elements of the periodic table. We all now know that carbon-based fossil fuels are driving global warming, threatening to disrupt all our lives, but could carbon come riding to the rescue? Our favourite chemist, Andrea Sella of University College London, takes us through the basic chemistry of carbon and we visit some of the world's leading materials scientists in two leading carbon research centres. At Manchester University we meet professor Aravind Vijayaraghavan, an expert in the revolutionary nano-material, graphene and two of his colleagues. We also get a tour of the National Composities Centre with its chief executive Peter Chivers. And, we meet Colin Sirett, head of research at the European aerospace group Airbus.

  • Elemental Business: Carbon Energy

    16/07/2014 Duración: 26min

    In our series examining the world economy from the perspective of the chemical elements, we look at how the industrial revolution was really an energy revolution driven by carbon-based fossil fuels. Chemistry professor Andrea Sella of University College London and his geology colleague professor Mark Maslin explain the chemical wizardry that makes carbon the ultimate fuel. We hear from Dr Paul Warde an industrial historian at the University of East Anglia, about how the 'C' element has powered the longest and most sustained economic boom in the history of humanity. But how long can it last? Can we expect the mother of all crashes when the carbon crunch finally comes? Two former oil men, Chris Mottershead, former head of energy security at BP and now vice principal for research at King's College in London and John Hofmeister, former president of Shell Oil, give us their perspectives on the whether the world is ready to tackle its addiction to fossil fuels, before the fuel runs out and in time to avert a loomin

  • Elemental Business: Gold

    15/07/2014 Duración: 23min

    What makes gold so valuable, why is it golden and why is it the only elelment that makes a good currency? In chemical terms it is virtually useless. Justin Rowlatt talks to one of the world's biggest manufacturers of mobile phones about how you can recover the gold in your handset and learns how little gold there actually is. Find out more in the latest in our series examining the world economy from the perspective of the building blocks of the universe - the chemical elements.

  • Elemental Business: Mercury

    14/07/2014 Duración: 23min

    Mercury is the bad-boy of the periodic table, often called 'quicksilver', it is both mesmerising and toxic as Professor Andrea Sella of University College London vividly explains. In the fourth of our series examining the global economics of chemical elements Justin Rowlatt speaks to Tim Kasten of the United Nations' Environment Programme who is one of the architects of a new international treaty that aims to ban the metal from industrial uses by 2020. As we discover, that ban will affect everything from coal-fired power stations to small-scale gold miners in developing countries, to the illumination of the lowly office. We visit a fluorescent bulb recycling plant outisde Norwich and speak to small scale gold miners in Ghana about how the ban might affect them. But it is all in a good cause, as Justin discovers when he visits one of the finest fishmongers in London.

  • Elemental Business: Aluminium

    13/07/2014 Duración: 27min

    We look at aluminium, a more dazzling metal than you may imagine. A sceptical Justin Rowlatt visits the lab of our perennial chemist, Andrea Sella, to find out why it is used in everything from drinks cans to packaging to insulation to window frames.This metal used to be incredibly rare, because it is so hard to extract from its ore, bauxite. We visit Britain's only aluminium smelter - in the Scottish Highlands - to find out why so much electricity is needed in the process.But once you have it, it can be used, recycled and re-used almost ad infinitum. As the stock of metal in circulation increases every year, we ask the world's biggest manufacturer of rolled aluminium sheets whether one day the world may not need to mine the metal at all any more. And, as if that were not enough, we dispatch Justin to tour the world's biggest aluminium car body shop to find out why vehicle manufacturers are dropping the use of steel in favour of its lighter rival.(Photo: Aluminium bodied Range Rovers in production at the Jagu

  • Elemental Business: Helium

    12/07/2014 Duración: 23min

    Helium is the second most abundant element in the universe but very rare on earth. Professor Andrea Sella of University College London, explains to Justin Rowlatt the properties that make this inert gas so useful. He explains where it comes from and where it goes to.Washington correspondent, Jonny Dymond, is out in the wilds of the Texas pan-handle to explore the US national helium reserve. And, we hear from the head of General Electric's Magnetic Resonance Imaging division - one of the world's biggest users of helium - on why the gas is so important in the fight against many diseases.

  • Elemental Business: Phosphorus

    11/07/2014 Duración: 20min

    In the first of Elementary Business - a new series of programmes about the chemical elements - Justin Rowlatt asks whether phosphorus poses the biggest looming crisis that you have never heard of. Since 1945, the world's population has tripled. Yet the fact that we've still managed to feed all those mouths is in no small part thanks to phosphates. We mine them, turn them into fertiliser, and then spread them onto our fields, whence they are ultimately washed away into the ocean. Justin speaks to chemist Andrea Sella to find out just why phosphorus is so vital to sustaining life, and modern agriculture. He also hears from Jeremy Grantham, a voice from the world of high finance, who warns that pretty soon Morocco may find itself with the dubious honour of a near-monopoly of the world's remaining phosphate supplies. And Justin travels to the lowly town of Slough, near London, to take a look at one new way of staving off the dreaded day when the world eventually runs out of the stuff.(Photo: The Thames Valley sew
