Hydroxide‐aluminum based nano‐energetic materials are new class of thermites which demonstrated high theoretical energy capacity of up to 50 kJ cm−3. Most of the hydroxide‐aluminum based systems exhibit a large gas generation (greater than two liters per gram) and high adiabatic combustion temperature (up to 3000 K), which ensures performance that attributes significantly for applications such as solid fuel propulsion, explosives, airbag deployment, etc. Thermodynamic calculations performed for a collection of 16 novel hydroxide‐based nano‐thermite systems show that most of the systems are stable. Four systems, based on bismuth, copper, nickel and cerium hydroxides, were mixed with aluminum to prepare nano‐thermites compositions. These formulations were tested to estimate the heat generation and pressure discharge values during the ignition. These systems were stable below ignition temperature, between 570–600 °C. The strongest performance was recorded for Al−Bi(OH)3 formulation with 5.6 kPa*m3 g−1 peak pressure, which is comparable to highest values reported in literature.

“…In the ascending order, these enthalpies (in kJ/mole) are: 32 (As), 68 (Sb), 227 (In), and 255 (Ga). 24 By considering the anion (As, Sb) sub-lattice, one can say that it is easier to remove the deposited As atoms from their sites than Sb atoms, which explains the observed As substitutions by Sb. In the cation sub-lattice, it is easier to remove the deposited In atoms, than Ga atoms, which makes In replacements by Ga more effective.…”

B 28, C3G13 (2010); 10.1116/1.3276429High-performance InAs/GaSb superlattice photodiodes for the very long wavelength infrared range Appl.A set of advanced characterization methods, including high-resolution X-ray diffraction (measurements and simulations), cross-sectional scanning tunneling microscopy, and high-angle annular dark-field scanning transmission electron microscopy is applied to quantify the interface roughness and atomic intermixing (in both cation and anion sub-lattices) in short period (6-7 nm) InAs/GaSb superlattices intended for mid-wavelength (M) and long-wavelength (L) infrared detectors. The undesired atomic intermixing and interface roughness in the L-samples were found to be considerably lower than in the M-samples. In all specimens, anion intermixing is much higher than that in the cation sub-lattice. Possible origins of these findings are discussed. V C 2014 AIP Publishing LLC.

Super-Earth ingestion can explain the anomalously high metal abundances of M67 Y2235

We investigate the hypothesis that ingestion of a terrestrial or super-Earth planet could cause the anomalously high metal abundances seen in a turn-off star in the open cluster M67, when compared to other turn-off stars in the same cluster. We show that the mass in convective envelope of the star is likely only 3.45 × 10 −3 M , and hence 5.2 M ⊕ of rock is required to obtain the observed 0.128 dex metal enhancement. Rocky planets dissolve entirely in the convective envelope if they enter it with sufficiently tangential orbits: we find that the critical condition for dissolution is that the planet's radial speed must be less than 40% of its total velocity at the stellar surface; or, equivalently, the impact parameter must be greater than about 0.9. We model the delivery of rocky planets to the stellar surface both by planet-planet scattering in a realistic multi-planet system, and by Lidov-Kozai cycles driven by a more massive planetary or stellar companion. In both cases almost all planets that are ingested arrive at the star on grazing orbits and hence will dissolve in the surface convection zone. We conclude that super-Earth ingestion is a good explanation for the metal enhancement in M67 Y2235, and that a high-resolution spectroscopic survey of stellar abundances around the turn-off and main sequence of M67 has the potential to constrain the frequency of late-time dynamical instability in planetary systems.
