The concept of the fuel cell, that is, a cell in which inert electrodes immersed in an electrolyte could he intimately contacted with a reacting fuel (e.g., hydrogen) and oxidant (e.g., air) and so generate an electric current, was demonstrated in 1839 by Grove and intensively studied by him during the next decade. 

Oppenheimer. Like the Chicago-based scientists before him, Oppenheimer and his researchers often clashed with Groves and the project engineers, who preferred to compartmentalize and control information about the project rather than exchange it freely among the scientists. At Los Alamos, Oppenheimer s approach prevailed. 

In anesthetized rats, amphetamine causes dose-dependent changes in neostriatal unit activity. Spontaneously aetive neostriatal cells are uniformly inhibited at low (<2.0 mg/kg, IP) doses. At intermediate doses, an initial exeitation precedes the inhibition, and, at high doses (>5.0 mg/kg, IP), the predominant effect is excitation (Groves and Rebec 1976). Regional differences in the direction, magnitude, and duration of the response of neurons in the neostriatum exist (Rebee and Curtis 1983).

Oxidizing enzymes use molecular oxygen as the oxidant, but epoxidation with synthetic metalloporphyrins needs a chemical oxidant, except for one example Groves and Quinn have reported that dioxo-ruthenium porphyrin (19) catalyzes epoxidation using molecular oxygen.69 An asymmetric version of this aerobic epoxidation has been achieved by using complex (7) as the catalyst, albeit with moderate enantioselectivity (Scheme 9).53... 

In 1983, Groves and Takahashi demonstrated that a nitrido-Mnvporphyrin underwent a nitrogen-transfer reaction via a tV-trifluoroacetylnitrenoid species to give an aziridine, when it was treated with trifluoroacetic anhydride (TFAA) in the presence of olefins (Scheme 31).141... 

What can all these studies suggest to the inorganic chemist interested in the controlled and fAcile catalytic oxidation of hydrocarbons Groves and coworkers have already shown that iron porphyrins in the presence of iodosylbenzene and peracids can be used for such catalytic reactions (37, 38). However, the cost of the oxidants makes such reaction uneconomical at this time. 

D. Dolphin Groves and his co-workers 9 have shown that ferrous perchlorate and hydrogen peroxide can carry out hydroxy-lations which bear close parallels to the P-450 mediated systems.
