Derek Bryce-Smith
Derek Bryce-Smith (1926–2011) was a chemist and professor of Organic Chemistry at the University of Reading from 1956 until his retirement in 1991. His work included organometallic chemistry, radical chemistry, photochemistry, environmental science, nutritional science and behavioural science. He was among the first to describe the dangers of tetraethyl lead, which was used for several decades as an anti-knock additive in petrol. Initially, his concerns were dismissed both by his fellow academics and by industrial interests. However, by the time of his death, only six countries had not outlawed leaded petrol, and the Royal Society of Chemistry gave him a silver medal in 1984 for his work in this area. He subsequently became convinced that the use of NPK fertilisers in agriculture resulted in a lack of the essential trace element, zinc Zinc is a chemical element with the symbol Zn and atomic number 30.

University Of Reading
The University of Reading is a public university in Reading, Berkshire, England. It was founded in 1892 as University College, Reading, a University of Oxford extension college. The institution received the power to grant its own degrees in 1926 by royal charter from King George V and was the only university to receive such a charter between the two world wars. The university is usually categorised as a red brick university, reflecting its original foundation in the 19th century. Reading has four major campuses. In the United Kingdom, the campuses on London Road and Whiteknights are based in the town of Reading itself, and Greenlands is based on the banks of the River Thames in Buckinghamshire. It also has a campus in Iskandar Puteri, Malaysia. The university has been arranged into 16 academic schools since 2016. The annual income of the institution for 2016–17 was £275.3 million of which £35.4 million was from research grants and contracts, with an expenditur ...

Liz Hodgkinson
Liz Hodgkinson (born 1945) is an author and journalist who has written more than 50 books. Her books have been translated into over 20 languages. She has also written articles for most of the major British national newspapers in London, and for magazines for women. She has taught journalism for a decade. Early life Hodgkinson was born Elizabeth Garrett, and grew up, in the small Cambridgeshire town of St Neots. She attended Huntingdon Grammar School, which was co-educational and which is now named Hinchingbrooke School. At the school, she became a close friend of Amaryllis Garnett and was influenced by the bohemian household of David and Angelica Garnett. She has written that her parents would have been happy enough for her to leave school at 16 and train as a secretary. "They had no idea of higher education or careers." However, she wanted more from a career, so she attended Durham University where she studied English. Hodgkinson has written that her period at university w ...

Zinc
Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size.The elements are from different metal groups. See periodic table. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ( electrowinning). Zinc is an essential trace element for humans, animals, plants and for microorganisms and is necessary for prenatal and postnatal development. It ...

Trace Element
__NOTOC__ A trace element, also called minor element, is a chemical element whose concentration (or other measure of amount) is very low (a "trace amount"). They are classified into two groups: essential and non-essential. Essential trace elements are needed for many physiological and biochemical processes in both plants and animals. Not only do trace elements play a role in biological processes but they also serve as catalysts to engage in oxidation and reduction mechanisms. The exact definition depends on the field of science: * In analytical chemistry, a trace element is one whose average concentration is less than 100 parts per million (ppm) measured in the atomic count or less than 100 micrograms per gram. * In biochemistry, an essential trace element is a dietary element that is needed in very minute quantities for the proper growth, development, and physiology of the organism. The dietary elements or essential trace elements are those that are required to perform vit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fertilizer
A fertilizer (American English) or fertiliser (British English; see spelling differences) is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply plant nutrients. Fertilizers may be distinct from liming materials or other non-nutrient soil amendments. Many sources of fertilizer exist, both natural and industrially produced. For most modern agricultural practices, fertilization focuses on three main macro nutrients: nitrogen (N), phosphorus (P), and potassium (K) with occasional addition of supplements like rock flour for micronutrients. Farmers apply these fertilizers in a variety of ways: through dry or pelletized or liquid application processes, using large agricultural equipment or hand-tool methods. Historically fertilization came from natural or organic sources: compost, animal manure, human manure, harvested minerals, crop rotations and byproducts of human-nature industries (i.e. fish processing waste, or bloodmeal from ...

Organometallic Chemistry
Organometallic chemistry is the study of organometallic compounds, chemical compounds containing at least one chemical bond between a carbon atom of an organic molecule and a metal, including alkali, alkaline earth, and transition metals, and sometimes broadened to include metalloids like boron, silicon, and selenium, as well. Aside from bonds to organyl fragments or molecules, bonds to 'inorganic' carbon, like carbon monoxide (metal carbonyls), cyanide, or carbide, are generally considered to be organometallic as well. Some related compounds such as transition metal hydrides and metal phosphine complexes are often included in discussions of organometallic compounds, though strictly speaking, they are not necessarily organometallic. The related but distinct term " metalorganic compound" refers to metal-containing compounds lacking direct metal-carbon bonds but which contain organic ligands. Metal β-diketonates, alkoxides, dialkylamides, and metal phosphine complexes are repres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Guardian
''The Guardian'' is a British daily newspaper. It was founded in 1821 as ''The Manchester Guardian'', and changed its name in 1959. Along with its sister papers ''The Observer'' and ''The Guardian Weekly'', ''The Guardian'' is part of the Guardian Media Group, owned by the Scott Trust. The trust was created in 1936 to "secure the financial and editorial independence of ''The Guardian'' in perpetuity and to safeguard the journalistic freedom and liberal values of ''The Guardian'' free from commercial or political interference". The trust was converted into a limited company in 2008, with a constitution written so as to maintain for ''The Guardian'' the same protections as were built into the structure of the Scott Trust by its creators. Profits are reinvested in journalism rather than distributed to owners or shareholders. It is considered a newspaper of record in the UK. The editor-in-chief Katharine Viner succeeded Alan Rusbridger in 2015. Since 2018, the paper's main news ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
