The faradaic admittance of electrochemical processes : III. The frequency dependence
(Elsevier, 1961)
Recent experimental studies have demonstrated the inadequacy of proposed equations for the faradaic admittance, particularly in respect to the frequency dependence. Existing treatments of the faradaic admittance can give ...
An alkaline phosphomonoesterase from Neurospora crassa
(Elsevier, 1961-11-25)
An alkaline phosphomonoesterase was purified 40-fold from mycelium of Neurospora crassa. The enzyme had a pH maximum of 8.9-9.0 with [beta]-glucerol phosphate as substrate and exhibited maximal activity in the presnece of ...
High temperature pile irradiation of the n -heptane-hydrogen system
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1961-12)
A pilot unit for the high-temperature irradiation of flowing reactants was designed for the beam port of a nuclear reactor. Radiation-thermal cracking of the n -heptane-hydrogen system was studied with molal H 2 /C 7 ...
Kinetic data from nonisothermal experiments: Thermal decomposition of ethane, ethylene, and acetylene
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1961-12)
A rigorous method was developed to account for nonuniform temperature distributions in the analysis of kinetic data. The rate constants cannot be determined directly since they are functions of temperature, so equations ...
A comparison of the properties of two forms of tyrosinase from Neurospora crassa
(Elsevier, 1961-12)
The differences between a thermostable (T) and thermolabile (T) form of tyrosmase from Neurospora crassa have been studied by means of a spectrophotometric technique using ascorbate or ferrocyanide. No significant differences ...
Purification and properties of an acid phosphomonoesterase from Neurospora crassa
(Elsevier, 1961-09-02)
An acid phosphomonoesterase was purified 1400-fold from mycelium of Neurospora crassa with a 40% recovery. The enzyme had a pH maximum of 5.6 with [beta]-glycerol phosphate or glucosamine 6-phosphate as substrates, and ...
Studies on the biosynthesis of cordycepin
(Elsevier, 1961-03-04)
The carboxyl carbons of acetate and isovalerate do not serve to any appreciable extent as precursors of cordycepin, thus arguing against the origin of cordycepose from pathways of isoprenoid biosynthesis. Exogenously added ...
Addition compounds of n-methyl cyclic imines with trimethylboron,
(Elsevier, 1961-03)
A manometric investigation was made of the addition compounds of trimethylboron with the N-methyl derivatives of ethylenimine (aziridine), trimethylenimine (azetidine), pyrrolidine and piperidine. The stability order ...
Some observations on the mechanics of drops in liquid-liquid systems
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1961-09)
Data on the rate of rise and distortion of drops in several liquid-liquid systems have been collected. These are compared with correlations developed by other investigators, and in some cases discrepancies between observed ...
