This study investigates the attachment of copper particles to self-assembled monolayers of mercaptobenzoic acids (MBA) on gold substrates. The carboxylate functional group of the MBAs coordinates with metal ions in solution and facilitates the electroless
The rate and equilibrium constants for reaction (1): NO 3 + Cl - back arrow over forward arrow} Cl + NO 3 - in aqueous solutions were studied by pulse radiolysis. The formation and decay of the nitrate radical, NO 3, and the dichloride radical, Cl 2 -, in
The acid dissociation constant of the hydroxyl radical in aqueous solution was determined by pulse radiolysis from the pH dependence of the rate constant for reaction of the OH/O - radical with benzoate ions. The rate constant and the pKa( OH) values were
Spectra of mercury, thallium, lead, and bismuth were photographed in the 70 A-250 A region on two grazing-incidence spectrographs with low-inductance vacuum sparks. About fifty-five 5p 6 5d-(5 P6 5f+5 P6 6p+5p55d 2 +5 P5 5d6s) transitions were identified

This user's guide describes the set of screens and an example analysis for CONCLIFE, user-friendly software for estimating the service life of concrete pavements and bridge decks exposed to sulfate attack and freeze-thaw deterioration. CONCLIFE uses three
Calcium hydroxide is one of the main reaction products resulting from the hydration of Portland cement with water. It is also one of the more soluble phases found in hydrated cement systems. The influence of calcium hydroxide dissolution and its effect on

We laser-cool single beryllium ions in a Paul trap to the ground (n = 0) quantum harmonic oscillator state with greater than 90% probability. From this starting point, we can put the atom into various quantum states of motion by application of optical and
