Thermodynamic Properties of Adsorption-Complexes in Heterogeneous Catalysis
The surfaces of adsorbents are highly non-uniform, yet small portions thereof are fairly uniform and in the case of dehydrogenation-catalysts and dehydration-catalysts these constitute active centers of catalysis.

Hyperfragments produced by K^o mesons from K^+ charge exchange
"Stacks of C-2 emulsion were exposed to neutral k mesons. These were produced by the charge exchange, in dense material, of K^+ mesons from the Berkeley Bovatron. Hyperfragments were found in these stacks. It is concluded that the hyperfragments were produced by K^o2 mesons in the K^o mode. These were generated by the decay of the K^o1 component of the K^o beam as would be expected from the Gell-Man Pais scheme. Other possible mechanisms of production of the hyperfragments have been considered and shown to be unimportant."

Neutron Economy of Various Converter Reactor Designs
The following report determines how many neutrons are being absorbed in various converter reactor designs, how many neutrons leak from the reactor and the breakdown between fast and thermal leakage. Another interest this paper examines is to determine how many neutrons are absorbed in thorium in the resonance region, at thermal energy, and in the blanket.

Local Fields With Terminating Expansions (x)
"The quantum theory problem of constructing explicitly a local Lorentz invariant model field theory which has an asymptotic particle interpretation and gives rise to an S matrix different from unity is discussed. It is proved that if a local covariant field H(x) has a complete current, the S matrix associated with this field is identically equal to unity. Results show that in order to get an interaction, the current is not allowed to have a terminating expansion in terms of a free field. The absence of a finite connection between a free field and an interacting field tended to confirm the belief that in local quantum field theories with particle interpretation the requirement of the existence of scattering forces in the physical states are such that it is not pos sible to identify them with a linear space spanned by ""free'' particle states."

Separations Chemistry, Quarterly Progress Report, April-June 1954
"Scale-up experiments on high temperature fuel recovery processes have included the dummy run phase on the handling of 1-kologram samples of molten, non-irradiated uranium in the hot cell. The next step involves the use of spent X-10 fuel slugs. Small scale experiments with X-10 uranium on the extaction of Pu with Mg show that as much as 80 per cent of the Pu can be removed in pone pass. Treatment of uranium with fused fluorides can remove at least 90 per cent of the Pu in one pass. Oxide scavenging with ZrO2 is very effective in removing rare earths.:

A Possible Method for Investigating the Selective Absorptions of X-Rays by Atomic Nuclei
This article aims at showing the possibility of observing the selective absorption of x-radiation by the so-called method of "autoindication" whose analogue is widely used in the physics of neutrons.

Economic Factors of MFP Thermoelectric Generators
"Mixed Fission Products (MFP) for use as a heat source for thermoelectric generators will become increasingly available in the coming years. The Atomic Energy Commission sponsored program on solidification of nuclear wastes is now entering the hot-bench scale test phase. During this phase approximately 5000 thermal watts of two year old MFP could be produced monthly. Two different types of hot calcination pilot plants are planned for installation at the Hanford National Laboratories in the 1964 to 1966 time period. Each of these plants should be able to produce 160,000 thermal watts of two year MFP and 16,000 thermal watts of ten year MFP on a monthly basis. A full scale plant for a 15,000 Mw(e) nuclear economy is estimated to produce four to five times as much MFP as either of the pilot plants. Costs will be dependent upon AEC policy in effect at the time the plant is operating."

Direct Current Electromagnetic Pumps
Abstract: "A number of direct current conduction type electromagnetic pumps for liquid metals were constructed. Pumping capacities of over 400 gpm and efficiencies of over 50 percent were obtained. NaK alloy at temperatures up to 400 C was used in the test. The large currents required were obtained from rectifiers or from a homopolar generator constructed for the purpose."

Present Status of Semiconductor Particle Counters
This review lists some of the salient features of semiconductor particle counters and cannot claim to contain an exhaustive listing of all the work in the field. Performance results on the surface-barrier counters as developed at California Institute of Technology are included as typical for this type of counter, though comparable results have been obtained elsewhere.

Progress letter No. 11 for January 1, 1960 through January 31, 1960
A stainless steel autoclave for superheated water corrosion test was installed and "conditioned". Tests were begun to investigate the feasibility of densifying slip cast stainless steel by means of liquid phase sintering. Attempts to prepare tubular fuel elements by vacuum forming were resumed. Although thick-walled vacuum formed casting have been sintered on the aluminum mandrels without cracking, this has not yet been accomplished with the think sections of interest.

An Investigation of Scaling of Zirconium at Elevated Temperatures : Quarterly Status Report No. 10; Sept. 2, 1955 to Dec. 2, 1955
As previously reported, zirconium undergoes large dimensional increases after scaling in air in a critical temperature range, 700 degree-1050 degree C. This finding was observed with specimens of a constant thickness (0;062 in.) To study the thickness effect, a number of specimens ranging in thickness from 0.020 to 0.200 in. were scaled in air at a temperature (900 degree C) where the growth is a maximum for a given time. Both cold rolled iodine sheet and forged iodide bar stock were used. to determine the effect of orientation, specimens from the forged bar were obtained such that the scaling surface was either parallel to or perpendicular to the long axis of the bar.
