Patent number: 10428037Abstract: Methods of synthesizing and purifying ethers are described. The synthesis and purification are achieved using an etherification technique followed by one or two fractional distillations. The etherification utilizes an element having low work function properties. Examples of low work function elements include, but are not limited to, metals or their hydrides, such as sodium, lithium or potassium or some combination thereof. This technique yields ethers of greater than 90% purity.Type: GrantFiled: October 26, 2017Date of Patent: October 1, 2019Assignee: The United States of America as Represented by the Secretary of the NavyInventors: John D.

Patent number: 9051401Abstract: A synthesis of a new pyrazole-containing monomer by means of an easily implemented two-step process. This monomer can be electropolymerized to yield a stable n-doping polymer that may easily be electrochemically characterized. It is demonstrated that the electrochemical behavior of the polymer films produced is dependent upon the conditions applied during electrodeposition. Films deposited by cycling only at relatively positive potentials (0 to 2000 mV) show less intense n-doping responses than those films obtained by scanning the applied potential throughout a wider range (?2000 mV to 2000 mV).Type: GrantFiled: February 3, 2014Date of Patent: June 9, 2015Assignee: The United States of America as Represented by the Secretary of the NavyInventors: David J.
