Factors Affecting Particle Retention in Thermal Field-Flow Fractionation
(2002)
In this paper, we report a range of factors which affect the retention of colloidal
particles in thermal field-flow fractionation (ThFFF). These results are observed among different
sizes of polystyrene (PS) latex particles ...
Synthesis of D -erythro-Dihydrosphingosine and D-xylo-phytosphingosine from a Serine-Derived 1,5-Dioxaspiro[3.2]hexane Template
(2002)
[reaction: see text] A serine-derived 1,5-dioxaspiro[3.2]hexane template is shown to be a useful precursor for both aminodiol and aminotriol sphingoid bases by its conversion to D-erythro-dihydrosphingosine and ...
