Effects of positive flame stretch on laminar burning velocities, and conditions for transition to unstable flames, were studied experimentally for freely propagating spherical flames at both stable and unstable preferential-diffusion conditions. The data base involved new measurements for H2/O2/N2 mixtures...
60–62]. In this case, the luminescent moiety [a Ru(II) dye or Pt-coproporphyrin (PtCP)] is linked to a targeted delivery vector, such as polyarginine or proline-rich peptides which escort the whole structure into the cell
In the case of Li0.55(Ni1/3Co1/3Mn1/3)O2, the thermal treatment causes less structural disorder, and therefore the general tendency to release O2 is slowed down because of the formation of a stable spinel phase during the thermal processes. However, the spinel phase observed in the case ...
4. The data are compatible with a linear four step mechanism in which a trapping center, or an associated catalyst, (S) successively accumulates four + charges. The S4+ state produces O2 and returns to the ground state S0. 5. Besides S0 also the first oxidized state S+ is stable in ...
Throughout the bubbling process, the pH of the a stable value of around 9 (pH of the unsaturated solution = 13 for KOH and LiOH). Then the gas is purged over the solution. The pure nitrogen gas is bubbled and purged in the solution to remove the dissolved oxygen gas and any ...
Germany) set to 37 °C. The O2concentration was increased stepwise from zero to 21% O2(corresponding to 0–210 µM dissolved O2). After ~ 20 min equilibration of the O2concentration and temperature in the sample, lifetime readings were taken at least 5 times to ensure stable and ac...
Cornell team offers prospect for more stable Li-air battery with ionomer SEIs 01 May 2017 Lithium-air (Li-O2) batteries are among the nost energy-dense electrochemical platforms for mobile energy storage, and are thus considered promising for electrified transportation. A number of severe challenges...
Monoolein-water-drug systems prepared using drugs with either a high solubility (propranolol) or a low solubility (pyrimethamine) were stable when stored in the dark at 4°C for up to 6 months with no significant change in release characteristics. Systems incorporating propranolol were unstable ...
They also showed that the compound was unstable and decomposed to a mixture of metallic copper and cuprite (Cu2O) when heated. Cuprous hydroxide may persist as a metastable (kinetically stable) compound, but due to its thermodynamic instability with respect to copper and water it cannot be the ...
This suggests the formation of a stable protein(s) complex with the 50% methylated DNA and the presence of a single F-300 recognition sequence on the P188 promoter sequence. Binding specificity of the protein(s) producing the retarded complex was confirmed by competition experiments; 100-fold ...
