Thermodynamics of thallium alkanoates V. Heat capacity and thermodynamic functions of thallium(I) n-decanoate from 6 to 480 K
(Elsevier, 1988-10)
The heat capacity of thallium(I) n-decanoate was measured by adiabatic calorimetry from 6 to 350 K and by d.s.c. from 200 through 480 K. Excellent overlap occurs over the common temperature range of both techniques. Four ...
Matrix elements for configuration d4s in a weak octahedral field using Racah methods
(Elsevier, 1969-07)
The general formula for matrix elements of configuration d4s in a weak crystalline field have been derived by means of Racah algebra. These have been explicitly applied to the case of d4s. The tabulated reduced matrix ...
The oxidation of ethylene-1,2-d2 over a silver catalyst studied by microwave spectroscopy
(Elsevier, 1978-03-30)
Stereospecific ethylene-1,2-d2 was oxidized to ethylene oxide-1,2-d2 over Ag catalysts in a flow reactor at 180-280 [deg]C. The epoxide products did not completely randomize for any of the reaction conditions explored. ...
Functional analogs for the reduction of certain nitrogenase substrates. Are multiple sites within the Fe/Mo/S active center involved in the 6e – reduction of N 2 ?
(Springer-Verlag; Society of Biological Inorganic Chemistry, 1996-12)
Reactivity studies of clusters that contain the MFe 3 S 4 cores (M = Mo, V) with catecholate, multicarboxylate (or DMF) ligands coordinated to the Mo (or V) atoms, and Cl ligands coordinated to the Fe atoms have been ...
Synthesis of 1-(2-aminopropyl)benzimidazoles, structurally related to the TIBO derivative R82150, with activity against human immunodeficiency virus.
(Elsevier, 1993-04)
A number of 1-(2-aminopropyl)-2-mercaptobenzimidazoles related to the TIBO derivatives R82150 have been prepared and tested for their activity against human immunodeficiency virus type 1 (HIV-1). These compounds were all ...
Structural and kinetic studies in propene oxidation over Sb oxide dispersed on TiO2
(Elsevier, 1991-02)
Antimony oxide dispersed on TiO2 was characterized using FTIR, Raman, and Auger spectroscopies as well as XRD. They indicate that the electronic environment about Sb is perturbed at low concentration suggesting that the ...
Properties of the cyanobacterial coupling factor ATPase from Spirulina platensis : II. Activity of the purified and membrane-bound enzymes
(Elsevier, 1986-02-15)
Cyanobacterial (Spirulina platensis) photosynthetic membranes and isolated F1 ATPase were characterized with respect to ATP activity. The following results indicate that the regulation of expression of ATPase activity in ...
