 | An experimental program was conducted to establish the sensitivity of explosives to the impact of regular steel fragments. Non-spinning rectangular fragments of 0.2 to 3.0 ounces were projected by explosive means at velocities both above and below that required for detonation. Velocities were measured by screens and by high speed photography. All data were obtained using either Pentolite or Cyclotol explosives. The results of the tests were compared with a ... |

|
| The electrical conductivities of aqueous 0.001, 0.01, 0.1, 1.0, and 3.0M LiC1 and of 0.001, 0.01, 0.1, and 1.0M CsC1 solutions have been measured at 1 atm over the temperature range -2 to +12 C. Although LiC1 is a water structure-maker and CsC1 a structure-breaker the Arrhenius activation energies of electrical conduction both show maxima near the temperature of maximum density. (Author) |

| The viscosity of 19.3% chlorinity sea water was measured with a rolling-ball type high pressure viscometer over the temperature range -2 to +12 C and at hydrostatic pressures up to 1,500 kg/sq cm. Above + 4 C the pressure-dependence of the viscosity of these solutions differs slightly from that of pure water. (Author) |

| The effect of hydrostatic pressure on the viscosity of pure water has been measured with a rolling-ball type of viscometer over the pressure and temperature ranges of 1 to 2,000 kg/sq cm and 2 to 20 C. The application of pressure tends to destroy the structured regions in liquid water. (Author) |

|
| The application of hydrostatic pressure, like the application of thermal energy, destroys the less dense, relatively ordered regions of hydrogen-bonded water in liquid water. But, in addition to being able to destroy the structured regions in bulk water, pressure, unlike temperature, also destroys the local water structure in the hydration atmospheres of ionic species in solution.

R. A. Horne; R. A. Courant; D. S. Johnson; LITTLE (ARTHUR D) INC CAMBRIDGE MA
|
| The Fe(II)-Fe(III) electron-exchange reaction and certain long-range biological redox reactions involve the transfer of electrons by a Grotthusstype mechanism over water bridges. The Grotthuss mechanism is also responsible for the anomalously great electrical conductivity acidic aqeuous solutions. At ordinary pressures the rate-determining step of the Grotthuss mechanism is the rotation of H2O, possibly H3O+, and not the actual proton flip itself. The Grotthuss mechanism is confined to the 'free', rotatable, ... |

| The activation energies, Ea, of electrical conduction for aqueous HCl solutions of various concentrations have been determined from precision cnductivity measurements over the temperature range -1 to -10 C. In contrast to normal ionic conduction in aqueous solution which exhibits a pronounced maximum in Ea near the temperature of maximum density, Ea for protonic conduction remains fairly constant. Protonic conduction is composed of two components: normal ionic conduction whose ratedetermining ... |

|
| Protonic conduction occurs by the Grotthus mechanism. Below about 0. 00am HC1, the lengths of the Grotthuss chains are determined by the temperature, but over the range 0.001m to about 0.5m, the chains are principally disrupted by other protons, thus in this range the chain length and the equivalent conductance depend on the cube root of the concentration. An Arrhenius-type equation is developed for describing the concentration dependence of the ... |

| Common Leclanche cells can deliver currents in the hundred microamp range even at very low temperature (-55 F). Measurements of the thermal masses of batteries indicate that they can be approximated by the thermal masses of their constituent cells. Inclusion of a term for the insulating effect of the air space between a battery and its insulation has improved the prediction of battery cool-down rates; however, the agreement between predicted ... |
