Summary
A novel graphene actuator triggers energetic materials for physical self-destruction (PSD) of information storage chips (ISCs). This system offers rapid, low-energy protection for sensitive data.
Area of Science:
- Materials Science
- Electrical Engineering
- Information Security
Background:
- Energetic materials offer rapid physical self-destruction (PSD) for information storage chips (ISCs).
- High electrical sensitivity of energetic materials necessitates controlled triggering mechanisms to prevent accidental activation by leakage currents or electrostatic forces.
- Existing methods lack efficient integration and reliable triggering for secure data destruction.
Purpose of the Study:
- To propose and validate a physical self-destruction (PSD) module for information storage chips (ISCs) using a graphene-based insurance actuator and energetic materials.
- To establish a force-balance relation for the graphene actuator to control the electrical interconnection and physical isolation of energetic materials.
- To determine the optimal copper azide dosage and parameters for reliable ISC destruction.
Main Methods:
- Heterogeneous integration of a graphene-based insurance actuator with energetic materials.
- Establishing force-balance relation between electrostatic van der Waals force and elastic recovery force for the graphene electrode.
- Numerical analysis of detonation wave stress and experimental preparation of graphene thin films and in situ copper azide.
- Testing the PSD module's response time, voltage requirements, and physical damage efficacy.
Main Results:
- The graphene actuator achieved physical isolation within 14 μs upon application of a 4.4-4.65 V signal.
- Optimized copper azide dosage (0.45-0.52 mg) reliably damaged ISCs (23.37-35.84 mm²) within a 0.05-0.25 mm gap.
- The system demonstrated effective and controlled physical self-destruction of information storage chips.
Conclusions:
- The proposed graphene-actuated energetic material system provides a viable solution for secure information storage chip physical self-destruction (PSD).
- The method ensures rapid response, low driving energy, and high applicability for information insurance.
- This technology enhances data security by enabling controlled and reliable destruction of sensitive information storage devices.

01:25Deleterious Substances in Aggregate
244
Deleterious substances in aggregates can be detrimental to the quality and durability of concrete. These substances include organic impurities like loam, which interfere with cement hydration and are usually present in the sand. These prevent a good bond between aggregate and cement paste. Organic impurities can be detected using the colorimetric test, where the darkness of a solution after agitation indicates the level of organic content.

01:14Diamagnetic Shielding of Nuclei: Local Diamagnetic Current
956
An applied magnetic field causes the electrons present in the molecule to circulate, setting up a local diamagnetic current within the molecule. The local diamagnetic current arising from circulating sigma-bonding electrons induces a magnetic field, Blocal that opposes the applied magnetic field, B0. The effective magnetic field experienced by these nuclei is given by the difference between the applied and local magnetic fields in a phenomenon called local diamagnetic shielding. Essentially,...

01:17Electron Paramagnetic Resonance (EPR) Spectroscopy: Organic Radicals
2.7K
Ideally, an unpaired electron shows a single peak in the EPR spectrum due to the transition between the two spin energy states. However, coupling interactions can occur between the spins of the unpaired electron and any neighboring spin-active nuclei. This hyperfine coupling results in hyperfine splitting, where the EPR signal is split into multiplets. The signals split into 2nI + 1 peaks, where n is the number of equivalent nuclei and I is the nuclear spin. These splitting patterns provide...

15.9K
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...

01:19Types of Collisions - II
8.0K
When two or more objects collide with each other, they can stick together to form one single composite object (after collision). The total mass of the object after the collision is the sum of the masses of the original objects, and it moves with a velocity dictated by the conservation of momentum. Although the system's total momentum remains constant, the kinetic energy decreases, and thus such a collision is an inelastic collision. Most of the collisions between objects in daily life are...

Schottky barrier diodes are specialized semiconductor devices characterized by their unique construction. This construction involves combining a metal layer with a moderately doped n-type semiconductor material. This combination leads to the formation of a Schottky barrier, a pivotal element that defines the diode's operational characteristics. The core functionality of Schottky barrier diodes is their capacity to allow current to flow in only one direction due to their distinctive...
