The best way to achieve a virgin state of a magnetized sample is to heat it up to a temperature high enough to destroy every magnetic order and thereafter cooling it down in a zero magnetic field. This procedure is often not possible because high tem

We report on the synthesis of the amphiphilic molecules 1,1,1-tris(mercaptomethyl)undecane and 1,1,1-tris(mercaptomethyl)dec-9-ene starting from the corresponding tris(hydroxymethyl) compounds. In addition we describe the synthesis of an amphiphilic
