Thermodynamics of copper sulfides IV. Heat capacity and thermodynamic properties of Cu1.90S from 5 K to 750 K, Cu1.95S from 5 K to 1000 K, Cu1.98S from 300 K to 1000 K, and Cu1.995S from 300 K to 750 K
(Elsevier, 1990-11)
The heat capacities of Cu1.90S, Cu1.95S, Cu1.98S, and Cu1.995S have been measured by adiabatic-shield calorimetry. All samples have been characterized by powder X-ray diffraction in the temperature interval studied. A ...
Thermodynamic properties of ammonium halogen stannates I. Heat capacity and thermodynamic functions of deuterated ammonium hexachlorostannate (ND4)2SnCl6 from 5.9 to 347 K
(Elsevier, 1990-02)
The heat capacity of deuterated ammonium hexachlorostannate (ND4)2SnCl6 was measured from 5.9 to 347 K by adiabatic calorimetry. The heat capacity is characterized by a [lambda]-shaped anomaly that reaches its maximum Cp,m ...
Analysis of bioproduct separation using gel-enclosed adsorbents
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1990-08)
The concept of “gel-enclosed” adsorbents was recently introduced for whole fermentation broth processing. The term “gel-enclosed adsorbents” in this paper refers to small adsorbent particles such as the ones used in affinity ...
Isolation and characterization of a second lectin (SNA-II) present in elderberry (Sambucus nigra L.) bark
(Elsevier, 1990-03)
A second lectin (SNA-II) has been isolated from elderberry (Sambucus nigra L.) bark by affinity chromatography on immobilized asialo-glycophorin. This lectin is a blood group nonspecific glycoprotein containing 7.8% ...
Hot-atom chemistry
(Kluwer Academic Publishers; Akadémiai Kiadó ; Springer Science+Business Media, 1990-09)
Research in the chemical effects of the nuclear transformations during the past 50 years is reviewed.
Hadamard transform photothermal deflection desitometry of electrophretically blotted proteins
(Elsevier, 1990)
Hadamard transform spatial multiplexing techniques are applied to laser densitometry in order to prevent the photo-induced degradation of sensitive materials. Photochemical and thermal degradations can often occur in point ...
Carbohydrate-binding specificity of the daffodil (Narcissus pseudonarcissus) and amaryllis (Hippeastrum hybr.) bulb lectins
(Elsevier, 1990-06)
The carbohydrate binding specificity of the daffodil (Narcissus pseudonarcissus; NPA) and amaryllis (Hippeastrum hybr.; HHA) lectins, isolated from extracts of their bulbs by affinity chromatography on immobilized mannose, ...
Characterization and regulation of phosphatidylglycerolphosphate phosphatase in Saccharomyces cerevisiae
(Elsevier, 1990-09-18)
Phosphatidylglycerophosphatase (EC 3.1.3.27) activity was characterized in mitochondrial extracts from Saccharomyces cerevisiae. The enzyme has a pH optimum of 5.5. Maximum activity occurs in the presence of Triton X-100 ...
Compound formation and melting behavior in theAB compound and rare earth oxide systems
(Elsevier, 1990-03)
Compound formation in the systems of the covalent compounds BeO, AlN, and SiC withR2O3(rare earth oxides) is described. Tentative phase diagrams of the AlNNd2O3 and AlNEu2O3 systems are presented.
