Patent number: 9758737Abstract: A method to generate dense, multi-cyclic diamondoid fuels from bio-derived sesquiterpenes. This process can be conducted with both heterogeneous and homogenous catalysts and produces the targeted isomers in high yield. The resulting multi-cyclic structures impart significantly higher densities and volumetric net heats of combustion while maintaining low viscosities which allow for use at low temperature/high altitude. Moreover, bio-derived sesquiterpenes can be produced from renewable biomass sources. Use of these fuels will decrease Navy dependence on fossil fuels and will also reduce net carbon emissions.Type: GrantFiled: October 19, 2016Date of Patent: September 12, 2017Assignee: The United States of America as Represented by the Secretary of the NavyInventor: Benjamin G.

Patent number: 9746300Abstract: A method of selectively increasing the sensitivity of an insensitive munition by inducing porosity or Joule heating in munitions assembly comprising a power source, an explosive apparatus and a fuze apparatus wherein the explosive apparatus contains a sensitized main explosive composition comprising a secondary explosive and a sensitizing agent. As a result, the otherwise insensitive munition is rendered sensitive to a propagating wave shock by approximately 10 to 25%. To this end, a voltage is applied across the main conductive explosive composition within the insensitive munition. Voltages above certain thresholds cause the decomposition of the explosive material or conductive binder, which leads to an increase in porosity, and therefore the shock sensitivity.Type: GrantFiled: February 9, 2016Date of Patent: August 29, 2017Assignee: The United States of America as Represented by the Secretary of the ArmyInventors: Paul Anderson, Alex Paraskos
