A biography of the life and achievements of chemist sir humphry davy

Thus it was certain that electrical forces could act generate current only when the electrolyte was capable of oxidizing one of the metals, and that the intensity of its effect the voltage generated was directly related to the reactivity of the electrolyte with the metal.

In his experiments, Davy ran a great risk; the respiration of nitric oxide may have caused severe damage of the mucous membrane.

He concluded that, contrary to the scientific opinion of the time, the divisions between the various "kinds" of electricity were illusory. Klug's most important work is concerned with the structure of spherical viruses.

It had been established to investigate the medical powers of factitious airs and gases gases produced experimentally or artificiallyand Davy was to superintend the various experiments.

Humphry Davy

After the death of his father, he met Gregory Watt, the son of a famous inventor. Berzelius was an early Swedish supporter of the new chemistry proposed a generation earlier by the renowned French chemist Antoine Lavoisierand he remained a forceful exponent of enlightenment science and progressive politics even as romanticism pervaded Sweden and Europe.

He went on to electrolyse molten salts and discovered several new metals, including sodium and potassiumhighly reactive elements known as the alkali metals.

Sir Humphry Davy (1778 - 1829)

His generalization elevated bases from their formerly passive role as mere substrates upon which acids reacted to form salts to substances having characteristic properties opposite those of acids.

Shortly after his return, he studied, for the Society for Preventing Accidents in Coal Mines, the conditions under which mixtures of firedamp and air explode.

He also coined the term protein while attempting to apply a dualistic organic chemistry to the constituents of living things. Berzelius originally devoted his career to physiological chemistrya field based upon the application of chemistry and physiology to substances derived from animals and plants.

His carefully prepared and rehearsed lectures rapidly became important social functions and added greatly to the prestige of science and the institution. He did not intend to abandon the medical profession and was determined to study and graduate at Edinburgh, but he soon began to fill parts of the institution with voltaic batteries.

Humphry Davy was also a great painter and three of his paintings dated about circa have been donated to Penlee House museum at Penzance. In recognition of his growing international reputation, Berzelius was elevated to a position of nobility in on the coronation of King Charles XIV John.

The horseshoe-shaped magnet A created a magnetic field through the disk D. He then tried passing current through molten compounds, and his persistence was rewarded when he was able to separate globules of pure metal by this means. His work led him to propose that the elements of a chemical compound are held together by electrical forces: Garnett quietly resigned, citing health reasons.

In both his paper [55] and his Nobel acceptance speech, [56] Zeeman made reference to Faraday's work. A specimen of one of these heavy glasses subsequently became historically important; when the glass was placed in a magnetic field Faraday determined the rotation of the plane of polarisation of light.

Faraday subsequently sent Davy a page book based on notes that he had taken during these lectures. Humphry Davy was born on 17 December in Penzance in Cornwall.

Faraday instead proposed that only a single "electricity" exists, and the changing values of quantity and intensity current and voltage would produce different groups of phenomena.Sir Aaron Klug OM HonFRMS PRS (born 11 August ) is a Lithuanian-born, South African-educated, British chemist and biophysicist, and winner of the Nobel Prize in Chemistry for his development of crystallographic electron microscopy and his structural elucidation of biologically important nucleic acid-protein complexes.

Jöns Jacob Berzelius: Jöns Jacob Berzelius, one of the founders of modern chemistry. He is especially noted for his determination of atomic weights, the development of modern chemical symbols, his electrochemical theory, the discovery and isolation of several elements, the development of classical analytical techniques.

As a chemist, Faraday discovered benzene, John Payne, was sacked and Sir Humphry Davy had been asked to find a replacement; thus he appointed Faraday as Chemical Assistant at the Royal Institution on 1 March The Electric Life of Michael Faraday.

Humphry Davy was born on 17 December in Penzance in Cornwall. He was apprenticed to a surgeon and aged 19 went to Bristol to study science.

Louis Pasteur

There he investigated gases. He prepared and. Sir Humphry Davy, 1st Baronet PRS MRIA FGS FRS (17 December – 29 May ) was a Cornish chemist and inventor, who is best remembered today for isolating, using electricity, a series of elements for the first time: potassium and sodium in and calcium, strontium, barium, magnesium and boron the following year, as well as discovering the elemental nature of chlorine and iodine.

Heroes and Villains - A little light reading. Here you will find a brief history of technology. Initially inspired by the development of batteries, it covers technology in general and includes some interesting little known, or long forgotten, facts as well as a few myths about the development of technology, the science behind it, the context in which it occurred and the deeds of the many.
