Acetic acid production from marine algae. Progress report No. 2, September 30--December 31, 1977

Description: Preliminary results on the production of acetic acid from marine algae by anaerobic fermentation indicate that the rate is quite fast. First order rate constants of 0.77 day/sup -1/ were observed. This rate constant gives a half-life of less than one day. In other words, with a properly designed product removal system a five day retention time would yield 98% of theoretical conversion. Determination of the theoretical conversion of marine algae to acetic acid is the subject of much experimentation. The production of one acetic acid molecule (or equivalent in higher organic acids) for each three carbon atoms in the substrate has been achieved; but it is possible that with a mixed culture more than one acetic acid molecule may be produced for each three carbons in the substrate. Work is continuing to improve the yield of acetic acid from marine algae. Marine algae have been found to be rather low in carbon, but the carbon appears to be readily available for fermentation. It, therefore, lends itself to the production of higher value chemicals in relatively expensive equipment, where the rapid conversion rate is particularly cost effective. Fixed packed bed fermenters appear to be desirable for the production of liquid products which are inhibitory to the fermentation from coarse substrates. The inhibitory products may be removed from the fermentation by extraction during recirculation. This technique lends itself to either conventional processing or low capital processing of substrates which require long retention times.

Adenosine triphosphate concentration in relation to microbial biomass in aquatic systems

Description: Analyses of adenosine triphosphate (ATP) extracted from a sediment community by the sulfuric acid method are complicated by inhibitions from inorganic and organic compounds. Inhibitions by inorganic compounds are reversible while those by organic compounds are irreversible. The primary inhibition by organic compounds results by complexing with acid-soluble fulvic acids which will prevent the detection of as much as 80% of the ATP present in a sample by the luciferin-luciferase reaction. Analytical techniques were developed to parially circumvent such interferences. Biomass interpretations from ATP concentrations in aquatic systems are complicated by the diversity of the microbiota and by the variability in the carbon to ATP ratio caused by environmental conditions. However, when levels of ATP are considered as a physiological condition of a sedimentary community, this data provide a means to interpret community metabolism not available hitherto.

Alternate HNS synthesis routes. Period covered: January--March 1977

Description: Process variations in the Hungarian patent procedure for production of hexanitrostilbene (HNS) through the air oxidation of TNT, with the primary objective the improvement of product yield, were not met with any degree of success. Investigation of the copper pyridinate/DMF route resulted in somewhat inconsistent and only approximate reproduction of the Hungarian results. Elimination of the 55 C process heating step results in curtailment of the production of HNS, and tends to favor the production of dipicrylethane (DPE). Variations thus far employed in the patent process in this study have produced no consistent yield improvement over the original procedure.

Ambipolar electric fields and turbulence studies in the Wisconsin levitated toroidal octupole

Description: Detailed studies of hot ion plasmas (T/sub i/ > T/sub e/) in the poloidal field octupole show that the ambipolar electric field which is perpendicular to the flux surfaces is well explained by the observed properties of the microturbulence structures in the plasma. The turbulence structure has been measured by correlation techniques which are carefully described. In these experiments, signals were studied which are aperiodic in time and space, short lived compared to the decay times of the bulk plasma parameters, short ranged compared to the machine size, and are therefore classified as microturbulence structures. The resulting spatial and temporal correlation functions (CFs) are well fitted to a Gaussian function and the associated correlation lengths or times are the half width at half maximum of the CFs. The correlation length is measured to be the ion gyro radius for the hot hydrogen plasma and somewhat less for the helium plasma.

Amorphous silicon solar cells. Quarterly report No. 2, 1 October 1976 to 31 December 1976

Description: Infrared absorption measurements have shown that discharge-produced a-Si contains approx. 16 at. % of bonded hydrogen when deposited near room temperature and that the hydrogen content decreases to approx. 2 at. % for a substrate temperature of approx. 500/sup 0/C. This variation in the concentration of bonded hydrogen appears to be responsible for a reduction in the optical gap as the substrate temperature increases. Improvements in the photoluminescence, the photoconductivity, and the collection efficiency of films after annealing at approx. 200 to 300/sup 0/C indicate that many defects within the gap are being annealed out of the films at these temperatures. The conduction behavior in the field regime of approx. 10/sup 4/ to 10/sup 5/ V/cm appears to be due to the Poole-Frenkel effect. At lower fields the conduction is ohmic and thermally activated, but the pre-exponential term sigma/sub o/ obeys the Meyer-Neldel rule (sigma/sub o/ = sigma/sub oo/exp(E/sub a//kT/sub o/)). Recent experiments with lightly doped, p-type a-Si indicate that this amorphous silicon is a good-quality solar cell material. Pd Schottky-barrier cells without antireflection coatings have shown no degradation after 4400 hours of continuous illumination (approx. 50 to 75 MW/cm/sup 2/).
