A downhole assembly comprises a first article; and a second article having a surface which accommodates a surface shape of the first article, wherein the first article is configured to provide a chemical, heat, or a combination thereof to facilitate the disintegration of the second article. A method comprises disposing a second article in a downhole environment; disposing a first article on the second article; the second article having a surface which accommodates a surface shape of the first article; performing a downhole operation; and disintegrating the first article to provide a chemical, heat, or a combination thereof that facilitates the disintegration of the second article.

A system for degrading a structure includes the structure formed of a degradable-on-demand material, an ignitor arranged to transfer heat to the structure; and, a mechanical impactor movable with respect to the structure, wherein the ignitor increases in temperature upon impact of the mechanical impactor into the ignitor, and heat from the ignitor initiates degradation of the structure.

The rate of combustion of an electrically operated propellant having a self-sustaining threshold of at least 1,000 psi is controlled to produce chamber pressures that are sufficient to produce a desired pressure profile in the airbag to accommodate a range of human factors and crash conditions yet never exceeding the self-sustaining threshold. The combustion of the propellant is extinguished to control the total pressure impulse delivered to the airbag. Propellants formed with an ionic perchlorate-based oxidizer have demonstrated thresholds in excess of 1,500 psi and higher.

A product includes a three-dimensional scaffold structure having an open cell geometry with interconnected channels for allowing continuous communication throughout a volume of the scaffold structure. The scaffold structure is configured to enhance mechanical strength of an energetic material. A fuel material is present in the scaffold structure and/or a second material is coupled to the scaffold structure. The fuel material is configured to increase an output of energy release relative to an output of energy release from the scaffold structure having the fuel material not present.
