Nemst, Walther Hermann

Walther Hermann Nemst, a German (1864-1941), applied the principles of thermodynamics to the chemical reactions proceeding in a battery. In 1889, he showed how the characteristics of the current produced could be used to calculate the free energy change in the chemical reaction producing the current.

Dividing both sides by —nE, we obtain the equation developed by the great German chemist Walther Hermann Nemst in 1889, when he was only 25 years old. (In his career, which culminated in the 1920 Nobel Prize, he also formulated the third law... 

In parallel, in 1900, Walther Hermann Nemst (1864-1941), a German physicist and chemist, developed the high-temperature electrolyte YSZ , based on zirconium dioxide (Zr02) stabilized by yttrium oxide (Y2O3) at a 15% mass ratio. The foundations were lain for high-temperature electrolyzers and batteries. 

Walther Hermann Nemst, the great German scientist, Nobel laureate in Chemistry, and father of the Third Law of Thermodynamics, had two Florentine disciples Luigi Rolla and Giorgio Piccardi. The latter became professor of physical chemistiy at the University of Florence. Piccardi had studied fluctuating phenomena well before Ilya Prigogine (1917-2003). His best disciple, later successor, was Enzo Ferroni who, upon Piccardi s retirement, was promoted to the Chair of Physical Chemistry at the Universily of Florence. Ferroni had also served as director of the Department of Chemistiy and Professor of Physical Chemistry at the Universily of Cagliari, Sardinia. 

It was Carnot who proposed the correlation between heat and work. Josiah Willard Gibbs discovered the phase rule and provided the theoretical basis of physical chemistry. And, it was Walther Hermann Nemst who proposed the third law of thermodynamics and contributed to the study of physical properties, molecular stmctures, and reaction rates. Jacobus Hendricus van t Hoff related thermodynamics to chemical reactions and developed a method for establishing the order of reactions. Nearing the... 

Walther Hermann Nemst (1864-1941) was a German physical chemist who is known for his theories behind the calculation of chemical affinity as embodied in the third law of thermodynamics, for which he won the 1920 Nobel Prize in Chemistry. Nemst also made fundamental contributions to the theory of electrolyte solutions. He is most known for developing the Nernst equation, one of the most fundamental equations of equilibrium electrochemistry. 

Nernst, Hermann Walther (1864-1941) German physical chemist. Nemst is best remembered for his contributions to electrochemistry and for discovering the third law of thermodynamics. His work on electrochemistry included the concept of the solubility product and the use of buffer solutions. In 1906 he stated a theorem concerning the entropy of crystals at absolute zero which, in slightly different form, became known as the third law of thermodynamics. He also studied photochemistry and wrote an influential book entitled Theoretical Chemistry (1893). He was awarded the 1920 Nobel Prize for chemistry. 

In 1889 Hermann Walther Nemst (1864-1941) gave a theoretical treatment of the electrode potential set up between a metal and a solution of its own ions. He regarded a metal electrode as exerting a solution pressure which is a measure of the tendency of the metal atoms to leave the electrode and enter the solution as ions. At equilibrium, this is balanced by the osmotic pressure of the ions in solution. Nemst derived an equation linking the magnitude of the electrode potential with the ionic concentration and the absolute temperature. 

Hermann Walther Nemst a German physicochemist (1864-1941) received Nobel Prize in chemistry (1920). Nernst s equation was published in 1889 in terms of concentrations. Some authors consider Nernst as the father of modern electrochemistry. 

The excellence of German chemistry in general, not just of its organic branch, is objectively attested by its share of Nobel Prizes during the first two decades of the award s existence. Of the seventeen prizes awarded between 1901 and 1921 nine were to German chemists Hermann Emil Fischer (1902), Johann Friedrich Wilhelm von Baeyer (1905), Edward Buchner (1907), Wilhelm Ostwald (1909), Otto Wallach (1910), Alfred Werner (1913), Richard Will-statter (1915), Fritz Haber (1918), and Walther Nemst (1920).
