The structure of SnO2 nanoparticles (avg. 5 nm) with a few layers water on the surface has been elucidated by atomic pair distribution function (PDF) methods using in situ neutron total scattering data and molecular dynamics (MD) simulations. Analysis PDF, prompt gamma, thermogravimetric data, coupled MD-generated D2O/OD configurations demonstrates that minimum concentration OD groups required to prevent rapid growth during thermal dehydration corresponds ~0.7 monolayer coverage. Surface...
Abstract The nature of various electrode‐electrolyte interfaces have been investigated using vibrational Raman spectroscopy. This novel application spectroscopy has provided previously inaccessible structural evidence on the environment close to electrode surface.
Hollow cylinders: Gallium- and gallium–zinc-seamed pyrogallol[4]arene nanoassemblies were studied in the solution phase through various methods. The results reveal their rearrangement from spheres solid state to toroids (see, for example, PgC4GaZn) illustrating structural flexibility of gallium metal-seamed frameworks. Detailed facts importance specialist readers are published as ”Supporting Information”. Such documents peer-reviewed, but not copy-edited or typeset. They made available...
We report simultaneous measurements of neutron-capture prompt gamma emissions as well neutron reflectivity on a polymer film with an embedded Gd layer. Enhanced \ensuremath{\gamma}-ray signals and reduced were observed when the standing waves resonantly amplified in film. Fitting both data is significant aid uniquely characterizing depth profile locating
Metal-containing tubes: The structures of several iron-containing C-methylpyrogallol[4]arene (PgC1) nanoassemblies were studied in both the solid and solution phases. have a tubular architecture with iron as part framework (see picture; gray C, red O, turquoise/blue Fe), magnetic analysis suggests canted or spiral arrangement centers.

Abstract We report data for Ag, Au, Bi, Cd, Co, Cs, Ga, In, Rb, Sb, Se, Te, TI, U and Zn determined by radiochemical neutron activation analysis in consortium samples of Belgica (B) 7904, Yamato (Y) 82042, 82162 86720 carbonaceous chondrites. These trace elements cover a wide volatility/mobility range give unique information on thermal histories meteorites. The results indicate the nature these Y-82042 proves to have volatile element pattern C2 ( ≡CM) chondrite petrologic characteristics CI...

Instrumental neutron activation analysis with both relative and k0 standardization was used in four experienced laboratories to determine element mass fractions single-wall carbon nanotube certified reference material (CRM) SWCNT-1. Results obtained were evaluated using the National Institute of Standards Technology (NIST) "Type B On Bias" approach yielded consensus values agreement Research Council Canada (NRCC) for Fe, Co, Ni, Mo provided fraction 13 additional elements, namely, Na, Mg,...
The accuracy of low-level hydrogen measurements with prompt gamma-ray activation analysis (PGAA) depends on identifying and accounting for all background H signals, including interfering which are investigated quantified in this work.
