In 1938, Lise Meitner, Otto Hahn, and Fritz Strassmann realized that, by bombarding heavy atoms such as uranium with neutrons, they could split the atoms into smaller fragments in fission reactions, releasing huge amounts of energy. We can estimate the energy that would be released by using Einstein s equation, as we did in Example 17.5.

The balanced equation that we will use for this stoichiometry explanation is the recipe for the manufacture of ammonia (NH3). This reaction was so important that the chemist responsible for it, Fritz Haber, was awarded the Nobel Prize. Ammonia is a gateway step in the manufacture of fertilizers, and its manufacture was a giant step in solving the problem of providing food to a world population growing at an exponential rate. The equation for the Haber process is... 

Even worse, Pauling found out in Zurich that he would not be the first to apply wave mechanics to the chemical bond. Two young German acquaintances of his, Walter Heitler and Fritz London, had beaten him to it. Working closely with Schrodinger, they had found a way to use the wave equation to create a mathematical model of a simple chemical bond. 

The earliest work on silicon-carbide-related fibers was by Verbeek and Winter (4). Using the principles developed earlier by Fritz and co-workers (5), Verbeek and Winter (4) reported that the high-temperature pyrolysis of tetramethylsilane or methylchlorosilanes gives branched polycarbosilane (PCS) polymers containing a structure with alternating silicon and carbon atoms (equation 1). 

Chu and coworkers observed that the indole ester (26) can be reduced selectively using pyridine-bo-rane/HCl (equation 81), but Fritz and coworkers found that the same conditions reduce both the indole double bond and the carbonyl group in ketone (27 equation 82) but only the indole double bond in amide (28 equation 83). ... 

The bubble formed at the wall grows by vaporization until it reaches a limiting volume when it detaches itself from the wall and rises. In slow growth this limiting volume is determined by the equilibrium of buoyancy and surface forces and the adhesion conditions at the wall. The decisive differential equation for this was first solved numerically by Bashfort and Adams [4.51]. Based on their solution, Fritz [4.52] later showed that there is a greatest volume VA for a vapour bubble, that can be represented in the form... 

It extends over a wider range of pressures than the simple equation (4.97) by Fritz and agrees well with this equation within its range of validity. 

Wilhelm Carl Werner Otto Fritz Franz Wien (1864-1928) became an assistant to Hermann v. Helmholtz at the Physikalisch-Technische Reichsanstalt in Berlin in 1890. It was there that he discovered the displacement law in 1893, and also published an equation for M s in 1896, that only slightly differed from Planck s law. Wien became Professor of Physics at the TH in Aachen in 1896, moved in 1899 to become a professor in Wurzburg, and once again changed to the University of Munich in 1920. In 1911 he was awarded the Nobel prize for Physics as an acknowledgement of his work on thermal radiation. 

A quantitative statement regarding the increase of the elution strength when switching from one eluent to another may be derived from the equation that was proposed by Fritz et al. [69] for the calculation of the background conductivity of a mobile phase with fully dissociated eluent ions ...

London, Fritz (1900-1954) was bom in Breslau, Germany (now Wroclaw, Poland). He fled Nazi Germany in 1933 and came to the United States in 1939 where he became naturalized in 1945. Together with his younger brother Heinz he formulated the London equations of superconductivity. 

In 1912 the German chemist Fritz Haber (1868-1934) developed the Haber process (Equation 15.6). The process is sometimes also called the Haber—Bosch process to honor Karl Bosch, the engineer who developed the industrial process on a large scale. The engineering needed to implement the Haber process requires the use of temperatures and pressures (approximately 500 "C and 200 to 600 atm) that were difficult to achieve at that time. 

Walter Heitler and Fritz Wolfgang London convincingly explained why two neutral atoms (like hydrogen) attract each other with a force so strong as to be comparable to the Coulomb forces between ions. Applying the Pauli exclusion principle when solving the Schrddinger equation is of key importance. Their paper was received on June 30,1927, by Zeitschrift fur Physik, and this may be eounted as the birth date of quantum chemistry. ... 

Figure 18 3. Dependence of the number-average molar mass on yield for the polymerization of anhydrous lauryl lactam with Xi= 0.01% lauric acid as initiator. Lines were calculated from Equation (18-19). For increased clarity, curves for 280, 300, and 32(fC were shifted toward increasing yield along the yield axis by 40, 80, and 120 units. (After H.-G. Elias and A. Fritz.)...
