Argon production rate

A Anaerobic adaptation was obtained by flushing the cells with argon. At indicated time points, samples were taken to measure the in vitro Fk-ase activity of C. reinhardtii (box), S. obliquus (circle), C. fusca (triangle), C. moewusii (diamond). While the activities of both Scenedesmus species are comparative low, the in vitro H -production rate of anaerobically induced C. moewusii cultures is 2 times higher than the activity of induced C. reinhardtii cultures. B Northern blots with equal amounts of total RNA isolated from an anaerobically adapted culture (2 h) and an uninduced reference culture (0 h) of C. moewusii. The upper blot was incubated with a RNA sample of the 3 UTR of the hydA 1 cDNA, while the lower blot was incubated with a RNA sample generated of the cDNA from the constitutively expressed sedoheptulose 1,7-bisphosphatasegene. 

The pressure of argon gas during atomization ranges from 0.03 to 0.1 MPa. The crucible diameter is 75 mm and its rotating speed is up to 400 radians/s. This combination of conditions gives a production rate up to 1 kg/min, l89l The CSC-atomized particles are either spherical or flaky. Spherical particles usually have smooth...

The micropyrolytic gas chromatography technique was applied to the identification of siloxane polymers and as an aid to the control of the reproducibility of cross-linked siloxane resins452. In the case of linear polymers the column packing was Apiezon M and a devolatilized linear siloxane polymer (the Hungarian product Hu-Au-120, mol. wt. 59000) supported on Celite. With a detector voltage of 1000 V, column temperature of 100 °C and argon flow rate 20 ml/min, the sample was applied in a solvent-free state to the heated wire-coil. Cross-linked siloxane polymers were analysed as solutions in butyl acetate on a solid support containing 10% linear siloxane polymer as stationary phase under similar conditions. 

Hydrogen production rates were measured using a Varian Model 3700 gas chromatograph (Walnut Creek, CA) equipped with a molecular sieve 5A column and a thermal conductivity detector. Argon was used as the carrier gas. 

A ball-shaped ceramic product 2(1 ON) was obtained in —50% yield. In another typical pyrolysis experiment carried out under argon, —40mg of 1(1) was placed in a quartz tube in a Winston-Salem Thermcraft furnace, which was heated to 1200°C at a rate of 10°C/min in a stream of argon (flow rate —200 cmVmin). The sample was sintered at the highest temperature for 1 h, which gave a ceramic product 2(12A) in —50% yield. 

Operating conditions in the case in linear polymers were as follows the column packing was 10% Apiezon M and a devolatilized linear siloxane pol3nner ( the Hungarian product Hu-Au-120, mol. wt-59000) supported on celite (80-120 mesh), detector voltage 1000 V column temperature lOO C argon flow rate 20 to 30 ml/min. The wire coil was heated for varying periods with a current of 3.1A. 

Under this constraint, it is not possible to produce new superheavy nuclides at greater neutron excess by cold fusion, or by hot fusion with heavy-ion beams with lower atomic numbers than argon. This is because of the neutron richness of the overshoot isotopes, daughters of the multiple emission of relatively proton-rich a particles in the decays of the " Ca-induced evaporation residues. Nevertheless, both reaction types offer advantages in the production rates of the known isotopes of superheavy elements with Z = 106-108 that are of interest to the radiochemist. As examples Direct production of the long-lived hassium isotope Hs is possible in the cold-fusion irradiation of ° Pb with radioactive Fe. From Fig. 2, the cross... 

Process is suited to sheet thickness less than 4 mm, heavier gauges become more expensive due to argon cost and decreased production rate. Helium/argon gas is expensive but may be viable due to increased production rate.
