Oxidation of Organic Compounds in Molten Salts
… of organic compounds in molten alkali metal nitrates containing manganates. It has been shown that controlled oxidation can be readily achieved with high specificity to give products in high yield with very short reaction times. In order to monitor concurrent changes in the melt, a novel …

The Solubility Product of Ferrous Sulfide in Solutions of Varying Ionic Strength
… of ferrous sulfide in aqueous solutions of potassium nitrate up to a concentration of 1 molar. |Ferrous sulfide was precipitated by bubbling hydrogen sulfide through solutions containing known concentrations of ferric nitrate and potassium nitrate. The concentration of ferrous ion in the …

Anaerobic transformations of Kepone by denitrifying bacteria
… by denitrifying bacteria grown on benzoate-nitrate medium. In enrichment cultures, Kepone was transformed more extensively than by pure cultures isolated from the enrichments. A gram negative-faculative rod, called K bacterium, transformed 8.8% of the Kepone in a benzoate-nitrate medium in …

The development of a portable vessel for the collection, storage, and utilization of solar thermal energy for household use
… heating test. Each vessel contained 5 kg of potassium nitrate and were composed of 1.7 kg of aluminum. They were heated with low cost, commercially available and unmodified, 1.5 m^2 parabolic solar cookers. The energy storage vessels were heated in an average time of 2 hours and 21 minutes. …

Transient and steady state electrochemical studies of transport dynamics and equilibria in thin polymer films containing redox centers
… (QPVP) modified electrodes in contact with potassium nitrate (KNO$\sb3$) solution. The goal was to intercompare the electron diffusion coefficient (D$\sb{\rm E}$) of the system obtained by transient and steady state electrochemical methods and to evaluate the effect of equilibrium changes in …

The development of Galleria mellonella as a model to test the toxicity of food additives
… from larvae administered sodium benzoate, sodium nitrate, potassium nitrate, however there was no significant changes seen in the fungicidal killing ability of haemocytes from larvae treated with potassium sorbate, potassium nitrite, caffeine, monosodium glutamate and creatine. Significant …

Structural supramolecular constructs of spheres and tubes
… hydantoins and a new crystal motif involving potassium nitrate and cucurbit[6]uril. The second project examined the solid state structure of C60 and C70 fullerene and how they interact with the cup shaped calixarenes. With the small addition of C70 that is comparable to that found in the …

Analysis of Strength Variation in Glass Due to Ion Exchange
… treated at various temperatures in air and in a potassium nitrate salt bath to induce an ion exchange process. All samples were then tested to failure in 4-point bending to assess the resulting Modulus of Rupture (MOR). Statistical analysis techniques and Weibull analysis were used to study the …

Effects of nickel toxicity on expression of genes associated with nickel resistance in white spruce (Picea glauca): Nickel translocation in plant tissues.
… results of the present study also show that that potassium nitrate (a common plant fertilizer) does have an effect on gene expression and can lead to toxicity in P. glauca plants at high concentrations. Overall, the findings of this research suggest that the low level of bioavailable nickel in …

Thermoplastic-based pyrotechnic compositions
… polymer matrices with oxidants such as potassium nitrate. More interesting are fluoropolymer matrices as these strong oxidants enable the design of non-gassing systems with suitable fuels. The presence of fillers dramatically increases the melt viscosity. The random packed limit for …

Electrochemical Oxidation of Individual Silver Nanoparticles: Exploring the Effect of Particle Shape, Capping Ligand, Electrolyte, and Potential on the Signal
… potential are appropriate. The presence of potassium chloride encourages the oxidation of polyethylene glycol capped particles at an increasing rate over time, but rarely allows oxidation poly-vinylpyrrolidone capped particles. Instead, these particles are better oxidized to silver oxide …
