Highly Dispersed SiO(x)/Al2O3 Catalysts Illuminate the Reactivity of Isolated Silanol Sites.

Angewandte Chemie (International ed. in English)

Mouat AR, George C, Kobayashi T, Pruski M, van Duyne RP, Marks TJ, Stair PC.
PMID: 26398359
Angew Chem Int Ed Engl. 2015 Nov 02;54(45):13346-51. doi: 10.1002/anie.201505452. Epub 2015 Sep 23.

The reaction of γ-alumina with tetraethylorthosilicate (TEOS) vapor at low temperatures selectively yields monomeric SiO(x) species on the alumina surface. These isolated (-AlO)3Si(OH) sites are characterized by PXRD, XPS, DRIFTS of adsorbed NH3, CO, and pyridine, and (29)Si and...

Phys Chem Chem Phys. 2017 Mar 15;19(11):7820-7832. doi: 10.1039/c7cp00811b.

Bastnäsite, a fluoro-carbonate mineral, is the single largest mineral source of light rare earth elements (REE), La, Ce and Nd. Enhancing the efficiency of separation of the mineral from gangue through froth flotation is the first step towards meeting...

Mutagenic and genotoxic effects of Anilofos with micronucleus, chromosome aberrations, sister chromatid exchanges and Ames test.

Cytotechnology

AIM: The aim was to report morphological and functional outcomes following modified early treatment diabetic retinopathy study (ETDRS) laser in diabetic macular edema (DME).MATERIALS AND METHODS: Structural and functional changes using spectral domain optical coherence tomography (OCT) and microperimetry...

The Temperature-Dependence of Multiphonon Relaxation of Rare-Earth Ions in Solid-State Hosts.

The journal of physical chemistry. C, Nanomaterials and interfaces

Yu D, Ballato J, Riman RE.
PMID: 28408967
J Phys Chem C Nanomater Interfaces. 2016 May 12;120(18):9958-9964. doi: 10.1021/acs.jpcc.6b01466. Epub 2016 Apr 05.

Rare-earth ions are used in a wide range of emissive devices - ranging from lasers to displays - where high optical efficiency and narrow-linewidth are important. While their radiative properties are important, nonradiative properties are also critical since they...

Estimating a graphical intra-class correlation coefficient (GICC) using multivariate probit-linear mixed models.

Computational statistics & data analysis

Yue C, Chen S, Sair HI, Airan R, Caffo BS.
PMID: 26190878
