The photoemission spectra of four different metal quinoline molecules, namely, the prototypical tris(8hydroxyquinolinato)-aluminum(III) (Alq3) complex and the related compounds Gaq3, Inq3, and tris-(9hydroxyphenalen-1oate)-aluminum(III) [Al(OP)3] are compared to the electronic structure computed with different first-principles methods. In general, we found that, for Alq3, Gaq3, and Inq3, the mo...

Approximately 100 billion aluminum cans are produced annually, mainly for the beverage industry. Early technologies for decorating the cans often used solvent-based coatings containing solvents at concentrations of -70% to 75% by volume (Randall 1992). The solvent composition was typically a mixture of aliphatic hydrocarbons, aromatics, ethers, cellosolves, and acetates. Unfortunately, this met...

Corrosion is the degradation or deterioration of metal components due to a reaction with the environment. Chromate conversion coating is applied to passivate metallic surface to slow down (and prevent to some extent) corrosion process. Chromate conversion process uses chromium compounds including hexavalent chromium, which is toxic, carcinogenic and hazardous to human health and environment. He...

To study the micromorphology and dynamic evolution law of copper aluminum composite interface evolution, ultra-high temperature laser Confocal microscopy (CLSM) was used to observe analyze in situ, then SEM, EDS other advanced material analysis methods were layer, composition layer formation process interface. The results indicate that is mainly related mutual diffusion atoms reaction between a...

In an article entitled, “A Study of the Possible Role of Aluminum Compounds in Animal and Plant Physiology,” by McCollum, Rask, and Becker,’ these authors arrived at the conclusion that, “Aluminum is not a constituent of either plant or animal matter.” Since this conclusion is so contrary to what has been found by all previous investigators, we have performed the following experiments in order ...

Astringency of aqueous solutions of phenolic compounds (grape seed tannins, tannic acid, catechin and gallic acid) increased upon addition of citric acid, whereas the astringency of alum was reduced. Astringency of alum was decreased equivalently by addition of equi-sour levels of lactic acid, citric acid or hydrochloric acid. The difference between alum and the phenolic compounds is speculated...
