An RTV silicone and high density polyethylene are exposed in an activated gas plasma for varying times and varying conditions. Both oxygen and argon are used. Changes in critical surface tension of wetting as determined by contact angle measurements are reported. Bondability of the treated surfaces is evaluated with b…
In modern microelectronics, complicated structures with very small dimensions must be fabricated on active-device materials. This task has been traditionally accomplished by photolithographic techniques, but electron-beam exposure of resist materials has recently been explored [1]-[3]. Submicron electron devices have…
The plastic deformation and strain hardening of NaCl crystals and f.c.c. crystals have much in common. The easy glide hardening rate for NaCl can be as low as that observed in copper. Random slip on the conjugate system can increase the hardening rate and cut short the easy glide extension. In Stage II of deformation,…

Abstract The effect of rubber particle size on the tensile properties of rolled and unrolled acrylonitrile‐butadiene‐styrene has been studied by considering model systems consisting of mixtures of a small particle (0.1 micron diam) rubber, S , and a large particle (0.56 micron diam) rubber, L , in an SAN matrix. Befor…
Weiss molecular field theory has been applied to spinels containing two types of ions carrying magnetic moment. By neglecting AA and BB interactions and considering only the four AB interactions between the two types of ion in the two types of site, it is shown that anomalous spontaneous magnetization curves can arise…
The motion of dislocations through randomly positioned localized and thermally-penetrable obstacles interacting with dislocations only at contact is in the form of local penetration and short range sideways’ unzipping ‘. Under an applied stress, the spacings of obstacles along the dislocation line obey a nearly expone…

A technique utilizing electroplating is described for the preparation of specimens for transmission electron microscopy, which show the relation between surface detail and internal structure. The cleared channels in deformed neutron irradiated copper crystals have been correlated with surface slip steps indicating tha…
X-ray photoelectron spectroscopic measurements of various valence states of Fe and Cu in several compounds using ion-sputtering reduction are presented, and the potential usefulness of this time-dependent and in situ method is discussed.

We report on the synthesis and the measurement of the properties of large single crystals of a new synthetic nonlinear optical material of the sulfosalt type, Tl(3)AsSe(3). The crystal space group is R3m; the refractive indices range from 3.14 to 3.44 with n(0) - n(e) = 0.18 (negative uniaxial), and the material is tr…
The equilibrium dielectric permittivity of pure decalin and the dielectric permittivity and loss of dilute solutions of chlorobenzene, bromobenzene, toluene, tetrahydrofuran, 1-fluoronaphthalene, 1-chloronaphthalene, 1-bromonaphthalene, and 1-methylnaphthalene in decalin have been measured from 50 Hz to 100 kHz at sev…
A study has been made of the relative thermoluminescence response to α- and β-radiation of six phosphors (two types of natural fluorite, CaF2: Mn, CaF2: Tb, CaSO4: Mn and quartz) using samples which are thin compared to the range of the α-particles. The α- and β-radiations induce the same glow peaks, but at low doses…
The lactate dehydrogenase (LDH) from Streptococcus mutans NCTC 10449 is under stringent metabolic control. The partially purified enzyme was specifically activated by high concentrations of fructose-1,6-diphosphate (FDP) and was inhibited by adenosine triphosphate. There appeared to be at least two binding sites for t…
Abstract Using methods described in a previous publication the optical activity of a number of polypeptides and proteins has been calculated. The systems included the α‐helix, the two β‐structures, polyproline I, polyproline II, collagen and collagen models, and poly‐ N ‐methylalanine. In addition to these orderded st…
In autoradiographic studies of tritium distribution in multiphase alloys, both the tritium within the metal and the emanated tritium contribute to darkening of the autoradiographic emulsion; and unless both are considered, erroneous conclusions about tritium segregation may be reached.
