The damage and residual strength of 7075-T6 aluminum panels exposed to caliber 0.50 AP M2 gunfire was found to vary with projectile velocity, impact angle, and target thickness. Maximum damage occurred at low velocities and high impact angles. The strength of thin panels agreed closely with fracture theory because of…

Aqueous solutions of LiNO2, NaNO2, KNO2 and CsNO2 generate only three Raman lines even though extremely high concentrations are attainable. The relative integrated intensities are proportional to concentration and show no specific cation dependence. The frequencies approach those of the corresponding solid. The halfwi…

The naphthoquinone acceptors form stable charge-transfer complexes in solutions of aprotic solvents with aromatic hydrocarbons as donors. From the charge-transfer transition energies of the complexes as well as from the polarographic half-wave reduction potentials of the acceptors relative electron affinities of the a…

The thermo-elastic solutions for the case of one heat source near a circular hole in an infinite elastic plate are given in the steady-state condition using the thermal expansion displacement for "zero stresses". It is assumed that the temperature along the edge of this hole is held at zero degree always. Numerical ca…

1,2,3,4-Tetrafluoronaphthalene undergoes nucleophilic and electrophilic substitutions in the fluorocarbon and in the hydrocarbon ring respectively. On treatment with sodium methoxide, hydrazine, and lithium aluminium hydride, the 2-fluorine atom is displaced predominantly. Bromination and nitration yield mixtures of c…

This paper discusses the affects of anodization parameters on the growth rate of plasma anodized . Variations in growth rate were inferred by observing the variations in the anodic current decay while anodizing at a constant bias potential. The following effects have been observed: (a) Sputtered cathode oxide was foun…

The solid-state (powder) i.r. (1000–40 cm–1) and Raman (1000–130 cm–1) spectra of sodium, potassium, and ammonium chromate(VI) and dichromate(VI) are reported and compared with the previously reported solution Raman spectra. Considerable splittings of the degenerate modes are observed and an attempt is made to account…

The reduction of Ni(II), Co(II), Cd(II), and Pb(II) was studied at glassy carbon electrodes in molten lithium chloride‐potassium chloride eutectic at 450°C using the technique of linear sweep voltammetry. Peak‐shaped voltammograms were obtained at scan rates of 10 mV to 1 V / sec . Linear dependence of peak currents o…

The i.r. and Mössbauer spetra of CdFe(CO)4 and of several complexes of the type L2MFe(CO)4(M = Zn or Cd; L = nitrogen donor ligand) have been recorded. The Mössbauer spectra indicate the presence of octahedrally co-ordinated iron atoms and, on this basis, possible structures for the complexes are discussed. The comple…

Abstract Oxidative reactions in cellulose are commonly initiated by thermal, ultraviolet, and high‐energy radiations and by chemical oxidation. Long‐lived free radicals, formed in cellulose on the localization of energy from thermal, ultraviolet, and high‐energy radiations, and short‐lived free radicals, formed in cel…

The energy levels of the I4 ground term of Er3+ in single crystals of CaWO4 were established by absorption and fluorescence spectra measurements. The measurements were made using crystals at temperatures of 2, 20, and 85°K. The energy level scheme allows an interpretation of the 1.612-μ four-level CaWO4:Er3+ laser tra…

Heats of immersion of pure and doped magnesia in cyclohexane were measured at 35°C for samples heated at different temperatures in vacuo. For the pure samples, rise in temperature of thermal treatment leads to a gradual decrease in the heats of immersion normalized per unit area (h1, ergs cm–2), till a certain limitin…
