We present an experimental and theoretical study of the structure of small, neutral gold clusters—Au _3 , Au _4 and Au _7 —‘tagged’ by krypton atoms. Infrared (IR) spectra of Au _N ·Kr _M complexes formed at 100 K are obtained via far-IR mul

We predict the structures of neutral gas-phase gold clusters ($Au_n$, $n$ = 5$-$13) at finite temperatures based on free-energy calculations obtained by replica-exchange ab initio molecular dynamics. The structures of neutral $Au_5$$-$$Au_{13}$ clust

Far- and mid-infrared multiple photon dissociation spectroscopy has been employed to study both the structure and surface reactivity of isolated cationic rhodium clusters with surface-adsorbed nitrous oxide, Rh(n)N(2)O(+) (n = 4-8). Comparison of exp

Dispersion of calcium oxide on high surface area γ-Al2O3 creates a stable and reversible CO2−sorbent that overcomes the problems associated with bulk CaO, such as limited long-term stability, slow uptake kinetics, and energy-intensive regeneration

In the presence of secondary alcohols, electrospray ionization of dilute methanolic solutions of nickel(II) salts and 1,1'-bis-2-naphthol (BINOL) leads to complexes of the formal composition [(BINOLato)Ni-(CH 3 CH(OH)R)] + (BINOLato refers to a singl

The effects of the oxidation state, the ligand, and the solvent on structures and energetics of cationic iron complexes are investigated by means of electrospray-ionization mass spectrometry. Insights into the potential-energy surfaces of FeX+, FeX2+

Vibrational spectra of small neutral gold clusters containing up to 8 Au atoms are measured in the far-infrared (46–222 cm –1) via photodissociation of their complexes with krypton atoms. Comparisons with calculated IR spectra for bare Au n clust

The geometry of cationic silicon clusters doped with vanadium, SinV⁺ (n=12–16), is investigated by using infrared multiple photon dissociation of the corresponding rare gas complexes in combination with ab initio calculations. It is shown that th

A series of vanadia catalysts supported on the mesoporous silica SBA-15 are synthesized using an automated laboratory reactor. The catalysts contain from 0.6 up to 13.6V atoms/nm2 and are structurally characterized by various techniques (BET, XRD, SE

The growth mechanisms of small cationic silicon clusters containing up to 11 Si atoms, exohedrally doped by V and Cu atoms, are described. We find that as dopants, V and Cu follow two different paths: while V prefers substitution of a silicon atom in
