Some numerical analyses on the solubility of vanillin in Carbitol® + water solvent mixtures

Description: This article reports solubility values of vanillin (component 3) in 2-(2-ethoxyethoxy)ethanol (Carbitol®, component 1) + water (component 2) mixtures at five temperatures from 298.15 to 318.15 K correlated with the Jouyban-Acree model combined with van't Hoff or Apelblat equations, and obtains models in second degree regarding the mixtures compositions.

From neural and social cooperation to the global emergence of cognition

Description: This article elaborates on a discussion of the emergence of intelligence via criticality as a consequence of locality breakdown, by using criticality for the foundation of a novel generation of game theory making the local interaction between players yield long-range effects.

Ion Beam Analysis of Microcrystalline Quartz Artifacts from the Reed Mound Site, Delaware County, Oklahoma

Description: This paper from the 23rd Conference on Application of Accelerators in Research and Industry conference proceedings evaluates the potential of particle induced X-ray emission spectrometry as a tool for future Ozarks chert provenance studies based on its ability to facilitate discrimination of Ozarks chert materials from different geological formations and identification of discrete groups of artifacts from the same geological formation.

20 Mule Team

Description: This photograph from the front cover of an issue of the Hexagon Journal displays the mock 20 mule team that stands outside of the Rio Tinto Borax Museum in Boron, California. The mule team depicts the original mode used to transport the chemical compound, borax, out of Death Valley between 1883 and 1888. A description of the photograph is shown on page 23 of the journal.

The Reaction Kinetics of Amino Radicals with Sulfur Dioxide

Description: Abstract: Application of the laser photolysis–laser-induced fluorescence method to the reaction NH2 + SO2 in argon bath gas yields pressure-dependent, third-order kinetics which may be summarized as 𝑘 = (1.49 ± 0.15) × 10^−31 (𝑇/298 K) − 0.83 cm^6 molecule^−2 s^−1 over 292 – 555 K, where the uncertainty is the 95% confidence interval and includes possible systematic errors.The quenching of vibrationally excited NH2 is consistent with a high-pressure limit for NH2 + SO2 of (1.62 ± 0.25) × 10^−11… more
