The detection techniques for traces of energetic materials (EMs) is achieved using fact interaction between fluorescent polymers and EMs. Researchers have designed various fluorophores for explosives detection worldwide. In present study, PAni, DBSA doped PAni (D‐PAni), γ‐Fe2O3PAni composite (Fe‐PAni), were synthesized and collectively used terminology as modified PAnis. This were employed for trace detection of EMs like TNT, RDX, PETN, and HNIW/CL‐20 and compared outcome with our earlier results of doped PAnis. All the synthesized PAnis were characterized by FT‐IR, X‐ray diffraction (XRD) and resonance Raman studies, UV–Visible, and photoluminescence (PL). The PL studies showed that quenching is selective and sensitive at ppm level (LOD about 0.04–1.50 μ mL−1) and Fe‐PAni emerged as a potential sensor (LOD; 0.092 ± 0.07 μ mL−1). The formation of polaron from bipolaron, the existence of exciton and intermolecular interactions were confirmed and evaluated from the spectrochemical studies.

“…The contactless method requires the remote probing of the sample by optical and electromagnetic field sources, which results in values of the impact velocity of the flyer and shock velocity. The arrival of the shock waves generates two electromotive forces that relate to the product of σ and thickness of sample (Gilev, 2011). The contact method requires typically four electrodes placed in contact with the sample.…”

“…Two electrodes provide the voltage measurements while the other two are used to input constant current. The interface temperatures are usually measured with an optical pyrometer (Gilev, 2011). The most fundamental shock wave characteristic of the sample is its principal Hugoniot curve, which is formed by the locus of shock states along a compression path from initial P, T, and density.…”

There is a considerable amount of literature on the electrical resistivity of iron at Earth’s core conditions, while only few studies have considered iron and iron-alloys at other planetary core conditions. Much of the total work has been carried out in the past decade and a review to collect data is timely. High pressures and temperatures can be achieved with direct measurements using a diamond-anvil cell, a multi-anvil press or shock compression methods. The results of direct measurements can be used in combination with first-principle calculations to extrapolate from laboratory temperature and pressure to the relevant planetary conditions. This review points out some discrepancies in the electrical resistivity values between theoretical and experimental studies, while highlighting the negligible differences arising from the selection of pressure and temperature values at planetary core conditions. Also, conversions of the reported electrical resistivity values to thermal conductivity via the Wiedemann-Franz law do not seem to vary significantly even when the Sommerfeld value of the Lorenz number is used in the conversion. A comparison of the rich literature of electrical resistivity values of pure Fe at Earth’s core-mantle boundary and inner-core boundary conditions with alloys of Fe and light elements (Si, S, O) does not reveal dramatic differences. The scarce literature on the electrical resistivity at the lunar core suggests the effect of P on a wt% basis is negligible when compared to that of Si and S. On the contrary, studies at Mercury’s core conditions suggest two distinct groups of electrical resistivity values but only a few studies apply to the inner-core boundary. The electrical resistivity values at the Martian core-mantle boundary conditions suggest a negligible contribution of Si, S and O. In contrast, Fe-S compositions at Ganymede’s core-mantle boundary conditions result in large deviations in electrical resistivity values compared to pure Fe. Contour maps of the reported values illustrate ρ(P, T) for pure Fe and its alloys with Ni, O and Si/S and allow for estimates of electrical resistivity at the core-mantle boundary and inner-core boundary conditions for the cores of terrestrial-like planetary bodies.

Electrical resistance measurements of aluminum foil are conducted under shock compression using the electric contact technique. Shock wave pressure p dependences of the electrical resistance R and the resistivity r are obtained for pressure range up to 22 GPa. The found dependence R(p) is a monotonically increasing smooth function of the pressure. The dependence r(p) is more complex: with increasing pressure, the electrical resistivity first decreases and then increases.
