The present invention relates to a nano-energetic material (nEM) composite having ignition and explosion characteristics by a low-power laser pointer beam and capable of being remotely and optically ignited by adding black powder to nEM composite powder, and a method of preparing the same. The nEM composite includes: nEM composite powder; and black powder used as a mediator for initial ignition to initiate ignition in response to a laser pointer beam and cause a nEM to be continuously ignited and consecutively explode by ignition heat.

An accelerator module is connected to an initiator module and generates supersonic waves from subsonic waves generated by the initiator module. The supersonic waves deliver particles to cells in tissues. The accelerator module may include a knocking-detonation transition metal and a detonation material. An example of the knocking-detonation transition metal is copper (I) 5-nitrotetrazolate. Another example of the knocking-detonation transition metal is lead azide. An example of the detonation material is pentaerythritol tetranitrate (PETN).

Embodiments include a method of forming an initiator. The method includes placing an energetic powder in a container. A solvent is added to the container and the solvent and energetic powder are mixed to form a slurry mixture. The slurry mixture is filtered. The filtered slurry mixture is placed in a transfer tube. The slurry mixture is applied to a bridge wire. The slurry mixture applied to the bridge wire is then dried.

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 device for the controlled initiation of a subdetonative reaction of an explosive charge arranged in a shell includes at least one explosive charge core extending in a region of a longitudinal axis of the explosive charge. A transverse dimension of the explosive charge core is adaptable to a radial extent of the shell in a longitudinal direction of the explosive charge, while a charging of the explosive charge core is set homogeneously or locally variably over a length of the explosive charge core with respect to a type of explosive material.
