sulfite > barium sulfite. The ratio of (mean diameter)2/time was dependent upon the concentration of the agar–agar gel (0.5%–2.0%) and the reaction temperature (0–40°C); the ratios decreased linearly with an increase of the gel concentration and increased with an increase of temperature...
These observations suggest that thermodynamic favorability for nucleation is governed by substrate–water interfacial energy, while given favorable thermodynamics, the rate is governed by ion attachment to substrates and incipient nuclei. 展开 DOI: 10.1021/acs.langmuir.6b01036 ...
XPS observations of the behaviour of these surface complexes show similarities with reaction steps in the mechanisms proposed for the hydrogenation of CO in the Fischer-Tropsch synthesis of hydrocarbons. Low-pressure hydrogenation of these adsorbates containing hydrocarbons and oxygen can led to the ...
(Supplementary Fig. 22;Supplementary Discussion), consistent with prior observations for other SWNT-based systems38,39. Importantly, no correlation could be made between cell viability and SWCNT filling material, indicating that the XRF contrast component was isolated from cellular processes by the ...
While this temperature dependence may be a result of reduced mobility in the GB core, two experimental observations point in the direction that space charge contribution, i.e., an effect of concentration rather than mobility, indeed is dominant. First, there is an inverse correlation between ...
which could be attributed to the surface charges produced on the BaTiO3nanoparticle due to its reaction with ethanol. This electrostatic charge keeps the BaTiO3nanoparticles from agglomerating as can be seen by the reduction in mean particle size compared with the untreated nanoparticles (from ~60...
which take on a morphology and crystalline structure depending on the chemical molecules that make up the reaction mixture. To evaluate the interaction of kaolinite with DNA, the objective of this work is to synthesize biomorphs in the presence of kaolinite and genomic DNA that comes from a prok...
This causes BaTiO3 to rid itself of the hydroxyl group on its surface with a coupling agent that can bond easily with epoxy as can be seen in Figure 27. The condensation reaction leads to the formation of water and BaTiO3 particles with a modified surface chemistry. This reaction makes the...
