Soluble cytochrome b5 from human erythrocytes
(Elsevier, 1972-07-12)
1. A hemeprotein with properties similar to microsomal cytochrome b5 has been detected in the supernatant fraction of hemolysates of human, beef, and rabbit erythrocytes. A method has been developed for determining the ...
A direct-elution technique for the recovery of thin-layer samples
(Elsevier, 1978-01)
An elution technique is described which permits the recovery of samples from flexible thin-layer chromatograms without removal of the layer from the plate. This simple method avoids many of the problems associated with ...
An investigation of the maximum experimental safe gap anomaly
(Elsevier, 1979)
The "safe gap" is defined as the maximum gap between two close-fitting, flat, machined metal surfaces that will just prevent an explosion within a vessel from producing a propagating combustion wave in the gases that ...
Assignments of the n[pi]* singlet states of p-benzoquinone
(Elsevier, 1974-03-30)
The vapor phase fluorescence spectra of p-benzoquinone-h4 and d4 are reported and discussed in relation to the assignment of the low lying singlet states. The low temperature, polarized single crystal electronic absorption ...
A new two-site model for hydroxyapatite dissolution in acidic media
(Elsevier, 1978-11)
A physical model featuring two distinct types of dissolution sites for hydroxyapatite (HAP) crystals is presented. One of these sites (site No. 1) is associated with dissolution along c axis dislocations of HAP crystals ...
Determination of adrenaline and noradrenaline by resonance Raman spectrometry
(Elsevier, 1976-01)
Aminochromes of adrenaline and noradrenaline show resonance Raman scattering at 1480 and 1430 cm-1 respectively, with Ar+ excitation. Scattering intensity is a linear function of concentration. Detection limits are 1 x ...
Separation of bile acids from neutral lipids on thin-layer chromatograms
(Elsevier, 1974-11-13)
