A detonation transfer assembly is disclosed. A detonation transfer assembly may comprise an external casing comprising an input end and an output end axially opposite the input end, an explosive column spanning axially inside the external casing, a primary explosive disposed within the explosive column, and a secondary explosive disposed within the explosive column axially between the primary explosive and the output end. The primary explosive and/or the secondary explosive may comprise a thermally insensitive initiation material that resists at least one of detonation or thermal degradation in response to temperature increase rate of 3.3° C. per hour over at least twenty hours.

A method and system for downhole operations that includes an energetic material with a reduced sensitivity to temperature, and a temperature rating that is higher than other energetic materials. Downhole tools that use energetic material thus can have a higher temperature rating with the reduced sensitivity energetic material. One embodiment of the energetic material includes an energetic heterocycle compound, such as 2,6-diamino-3,5-dinitropyrazine-1-oxide.

The present invention relates to the field of manufacturing nanoparticles, and specifically to a method for manufacturing diamond nanoparticles, or nanodiamonds, by detonation at least one explosive charge, wherein said at least one explosive charge is nanostructured.

The present disclosure relates to a trunkline delay detonator and a blast-triggering device using the same. In the blast-triggering device, a trunkline delay detonator is inserted into a connector in such a manner that a plurality of shock tubes connected to a detonator for initiating an explosive are interposed between the connector and the trunkline delay detonator, so that an explosion signal is applied to the shock tubes by detonation of the trunkline delay detonator. In the blasting detonator, close contact between the outer surface of the trunkline delay detonator and the shock tubes is improved, whereby energy lost in an explosion is reduced and an explosion signal is stably and uniformly applied to the shock tubes by using powder which has a weak explosive power and is relatively insensitive compared to conventional powders.
