Thermite compositions from low temperature impact milling

A thermite composition includes at least one composite particle having a convoluted lamellar structure having alternating metal oxide layers including a metal oxide and metal layers including a metal capable of reducing the metal oxide. The metal oxide layers and metal layers both have an average thickness of between 10 nm and 1 ?m. Molar proportions of the metal oxide and metal is within 30% of being stoichiometric for a thermite reaction

Thermite Compositions, Articles and Low Temperature Impact Milling Processes for Forming the Same

A process for the preparation of composite thermite particles, and thermite particles and consolidated objects formed from a plurality of pressed composite particles. The process includes providing one or more metal oxides and one or more complementary metals capable of reducing the metal oxide, and milling the metal oxide and the metal at a temperature below -50 °C, such as cryomilling, to form a convoluted lamellar structure. The average layer thickness is generally between 10 nm and 1 µm. The molar proportions of the metal oxide and metal are generally within 30% of being stoichiometric for a thermite reaction

Studies on the anti-asthmatic and antitussive properties of aqueous leaf extract of Bryophyllum pinnatum in rodent species

AbstractObjectiveTo evaluate the antiasthmatic and antitussive properties of the aqueous leaf extract of Bryophyllum pinnatum (B. pinnatum) (BP) Lam.MethodsOvalbumin-sensitized guinea pigs which were treated with BP for 21 consecutive days were exposed to 0.2% histamine aerosol in a glass chamber. Mucus viscosity, white blood cell and lymphocyte counts and tracheal wall morphometry were measured. Bouts of cough were counted pre and post acute exposure of extract-treated (× 7 d) guinea pigs to 7.5% citric acid aerosol in a chamber. Phenol red expectoration was estimated in mice after 7 d of daily administration of BP.ResultsDoses of 200 and 400 mg/kg/day (×21 d) BP significantly increased the time for guinea pigs to experience preconvulsive dyspnoea. BP and salbutamol (0.5 mg/kg/day ×21 d) reduced mucus viscosity in the sensitized group to values comparable with controls. White blood cell, lymphocyte counts and tracheal morphometry were not significantly altered. Both doses of BP also significantly reduced the bouts of cough but only 400 mg/kg/day significantly inhibited the amount of phenol red secreted.ConclusionsBP has demonstrated antiasthmatic and antitussive properties in these rodent models. These properties may underscore its use in Nigerian ethnomedicine

Quantitative transcription factor binding kinetics at the single-molecule level

We have investigated the binding interaction between the bacteriophage lambda repressor CI and its target DNA using total internal reflection fluorescence microscopy. Large, step-wise changes in the intensity of the red fluorescent protein fused to CI were observed as it associated and dissociated from individually labeled single molecule DNA targets. The stochastic association and dissociation were characterized by Poisson statistics. Dark and bright intervals were measured for thousands of individual events. The exponential distribution of the intervals allowed direct determination of the association and dissociation rate constants, ka and kd respectively. We resolved in detail how ka and kd varied as a function of 3 control parameters, the DNA length L, the CI dimer concentration, and the binding affinity. Our results show that although interaction with non-operator DNA sequences are observable, CI binding to the operator site is not dependent on the length of flanking non-operator DNA.Comment: 34 pages, 10 figures, accepted by Biophysical Journa
