Extractions: Heyrovsky, Jaroslav Jaroslav Heyrovsky was born in Prague on 20th December, 1890, the fifth child of Leopold Heyrovsky, Professor of Roman Law at the Czech University of Prague, and his wife Clara, née Hanl. He obtained his early education at secondary school till 1909 when he began his study of chemistry, physics and mathematics at the Czech University, Prague. From 1910 to 1914 he continued his studies at University College, London, under Professors Sir William Ramsay , W. C. Mc. C. Lewis and F. G. Donnan, taking his B.Sc. degree in 1913. He was particularly interested in working with Professor Donnan, on electrochemistry. During the First World War Heyrovsky did his war service in a military hospital as dispensing chemist and radiologist, which enabled him to continue his studies and to take his Ph.D. degree in Prague in 1918 and D.Sc. in London in 1921. Heyrovsky started his university career as assistant to Professor B. Brauner in the Institute of Analytical Chemistry of the Charles University, Prague; he was promoted to Associate Professor in 1922 and in 1926 he became the first Professor of Physical Chemistry at this University. Heyrovsky's invention of the polarographic method dates from 1922 and he concentrated his whole further scientific activity on the development of this new branch of electrochemistry. He formed a school of Czech polarographers in the University, and was himself in the forefront of polarographic research. In 1950 the Professor was appointed Director of the newly established Polarographic Institute which has been incorporated into the Czechoslovak Academy of Sciences since 1952.

Extractions: This was tedious work. A voltage was applied to a DME and a reference electrode was immersed in a test solution. After 50 drops of mercury were collected, they were dried and weighed. The applied voltage was varied and the experiment repeated. Measured weight was plotted vs. applied voltage to obtain the curve. By its regular dropping from the glass capillary the dropping mercury electrode maintains its pure surface; that guarantees exact reproducibility of measurements. , Cd , Mn , and Ba . He nevertheless realized that publication in the Czech language limits the news to a relatively small circle, and so he prepared an English version dealing with electrodeposition of alkali and alkaline earth metals, which was published in Philosophical Magazine. He followed Newtons motto A man must resolve either to put out nothing new or to become a slave to defend it. On 6 th extraordinarius Masuzo Shikata polarograph and for the studies of electrolysis with the dropping mercury electrode, coined the term polarography.

Extractions: Your Majesties, Royal Highnesses, Ladies and Gentlemen. Analytical chemistry is a science, fundamental not only to the other branches of scientific chemical research, but also to applied chemistry, the chemical industry. Further it is important for the other natural sciences, both within inorganic and organic Nature, for medical research, and for many humanistic and even jurisprudential sciences. The striving of analysts is not only to develop methods yielding accurate results, but even more important for practical work is that the analysis can be carried out rapidly, that it can be done using as small samples as possible, and that very small percentages of various substances can be detected and ascertained. Polarography is one of these micro-methods which are available to the modern analyst. Professor Bohumil Kucera of Prague once suggested to the young Jaroslav Heyrovsk that he should study certain irregularities in connection with the capillarity of mercury and attempt to disclose their origin. This was one of the innumerable small problems constituting science. Heyrovsk let the mercury flow through a glass capillary and weighed the drops. It was a slow and tedious method, and he resolved instead to measure the electric current obtained when he put a tension between the mercury in the capillary and that collecting at the bottom. The glass capillary does not terminate in the air, but in a solution, through which the current now will flow.

Extractions: (January, 2005) Simple principle of polarography is the study of solutions or of electrode processes by means of electrolysis with two electrodes , one polarizable and one unpolarizable , the former formed by mercury regularly dropping from a capillary tube . An objective document of polarographic study is the polarographic curve, that is, a curve visualizing the processes occurring in the course of electrolytic polarization of the dropping mercury electrode . In the case of the common voltage -controlled (or, with three-electrode systems potential -controlled, or " potentiostatic ") electrolysis, the polarographic curve is a current -voltage (or current-potential) curve showing the dependence of the current, passing through the system, on the voltage applied to the electrodes, or on the electrochemical potential of the dropping electrode. In the case of the current-controlled (" galvanostatic ") electrolysis, it is the time-change of potential of the dropping electrode, which is displayed by the curve. The dropping mercury electrode keeps the interface always fresh between its constantly renewed surface and the solution, independent of the processes that were taking place at previous drops, and thereby the measurements taken with it are perfectly reproducible. Polarography was created in 1922 when Jaroslav Heyrovsky used dropping mercury electrode for measuring

The Czech Republic - or rather Czechoslovakia - has two Nobel Prize winners in its history. One of them was scientist Jaroslav Heyrovsky, the other was poet Jaroslav Seifert. Today I'll acquaint you with the first of the two, who received this honour for a new invention in the field of chemistry - polarography. Jaroslav Heyrovsky I had the pleasure of meeting Jaroslav Heyrovsky's children, his daughter - Dr. Jitka Cerna and his son, Dr. Michael Heyrovsky, who works at the Jaroslav Heyrovsky Institute of Physical Chemistry at the Czech Academy of Sciences in Prague. As I myself am not an expert in science, I asked him to explain what polarography - his father's invention - was?

Die diesjährige Verleihung soll Anlass für uns sein, einmal einen Blick auf tschechische Preisträger zu werfen bzw. auf Preisträger, die in den Böhmischen Ländern das Licht der Welt erblickten. Derer sind es insgesamt fünf: als erste erhielt 1905 die Pragerin Bertha von Suttner, geborene Kinsky den Friedens-Nobelpreis. Ihr folgte 42 Jahre später das Ehepaar Carl und Gerta Cori. Weitere 12 Jahre später, also 1959, erhielt der Chemiker Jaroslav Heyrovsky einen Nobelpreis. Das letzte Mal wurde 1984 ein Tscheche mit diesem Preis ausgezeichnet: der Dichter Jaroslav Seifert erhielt den Nobelpreis für Literatur. Im heutigen Kapitel aus der tschechischen Geschichte wollen wir Ihnen diese Nobelpreisträger vorstellen.
