摘要:A method of monitoring the synthesis of a PGO spin-coating precursor solution includes monitoring heating of the solution with a UV spectrometer and terminating the heating step when a solution property reaches a predetermined value. The method utilizes the starting materials of lead acetate trihydrate (Pb(OAc) 2 .3H 2 O) and germanium alkoxide (Ge(OR) 4 (R=C 2 H 5 and CH(CH 3 ) 2 )). The organic solvent is di(ethylene glycol)ethyl ether. The mixed solution of lead and di(ethylene glycol)ethyl ether is heated in an atmosphere of air at a temperature no greater than 190° C., and preferably no greater than 185° C. for a time period in a range of approximately eighty-five minutes. During the heating step the solution properties are monitored to determine when the reaction is complete and when decomposition of the desired product begins to take place. The solution is then added to germanium di(ethylene glycol)ethyl ether to make the PGO spin-coating solution. This second step also entails heating the solution to a temperature no greater than 190° C. for a time period in a range of 0.5 to 2.0 hours. This heating step is also monitored with a UV spectrometer to determine when the heating step should be terminated. The process results in a PGO precursor solution suitable for use in spin-coating.

摘要:The present disclosure is directed to a process and intermediates for the synthesis of Vitamin D 3 metabolites such as 1,25-dihydroxycholecalciferol, 25-hydroxycholecalciferol and 24R,25-dihydroxycholecalciferol from 17-keto steroids via intermediates having the natural steroid configuration at the 20-position. These novel intermediates are prepared from 17-keto steroids by reaction with ethyltriphenylphosphonium halides followed by reaction with formaldehyde to form comounds having the natural steroid configuration at the 20-position and which are suitable substrates for the preparation of the aforementioned Vitamin D 3 metabolites.

摘要:The present invention provides methods for synthesis of IV–VI nanostructures, and thermoelectric compositions formed of such structures. In one aspect, the method includes forming a solution of a Group IV reagent, a Group VI reagent and a surfactant. A reducing agent can be added to the solution, and the resultant solution can be maintained at an elevated temperature, e.g., in a range of about 20° C. to about 360° C., for a duration sufficient for generating nanoparticles as binary alloys of the IV–VI elements.

摘要:A method of forming monodisperse metal chalcogenide nanocrystals without precursor injection, comprising the steps of: combining a metal source, a chalcogen oxide or a chalcogen oxide equivalent, and a fluid comprising a reducing agent in a reaction pot at a first temperature to form a liquid comprising assembly; increasing the temperature of the assembly to a sufficient-temperature to initiate nucleation to form a plurality of metal chalcogenide nanocrystals; and growing the plurality of metal chalcogenide nanocrystals without injection of either the metal source or the chalcogen oxide at a temperature equal to or greater than the sufficient-temperature, wherein crystal growth proceeds substantially without nucleation to form a plurality of monodisperse metal chalcogenide nanocrystals. Well controlled monodispersed CdSe nanocrystals of various sizes can be prepared by choice of the metal source and solvent system.
