BACKGROUND Genetic alterations in cellular signaling networks are a hallmark of cancer, however, effective methods to discover them are lacking. A novel form of abnormality called acquired uniparental disomy (aUPD) was recently found to pinpoint the region of mutated genes in various cancers, thereby identifying the region for next-generation sequencing. METHODS/PRINCIPAL FINDINGS We retrieve...
Waterand alcohol-soluble AuPd nanoparticles have been investigated to determine the effect of the organic stabilizing group on the thermal conductance G of the particle/fluid interface. The thermal decays of tioproninstabilized 3-5-nm diameter AuPd alloy nanoparticles, thioalkylated ethylene glycol-stabilized 3-5-nm diameter AuPd nanoparticles, and cetyltrimethylammonium bromide-stabilized 22-n...
Acquired homozygosity in the form of segmental acquired uniparental disomy (aUPD) has been described in follicular lymphoma (FL) and is usually due to mitotic recombination. SNP array analysis was performed with the use of the Affymetrix 10K 2.0 Gene-chip array on DNA from 185 diagnostic FL patients to assess the prognostic relevance of aUPD. Genetic abnormalities were detected in 118 (65%) of ...
In this research, a facile and effective approach was developed for the preparation of well-designed AuPd alloyed catalysts supported on magnetic halloysite nanotubes (HNTs@Fe₃O₄@AuPd). The microstructure and the magnetic properties of HNTs@Fe₃O₄@AuPd were confirmed by transmission electron microscopy (TEM), high resolution TEM (HRTEM), energy-dispersive X-ray spectroscopy (EDS), and vibrating ...
AuPd nanoparticles are formed on fluorine-doped tin oxide (FTO) by a nanosecond laser irradiation-induced dewetting process of deposited AuPd films. In particular, we analyze the effect of the surface topography of the substrate on the dewetting process and, so, on the final mean size of the formed nanoparticles. In fact, we used two supporting FTO substrates differing in the surface topography...
Homogeneously alloyed bimetallic particles of AuPd with an average size of ca. 2 nm were successfully prepared by simultaneous sputter deposition of Au and Pd in an ionic liquid in the absence of any additional stabilizing agents. The chemical composition of the AuPd alloy was tunable depending on the area fraction of Au plates in the Au-Pd binary targets for sputtering. The particles were immo...
The nanoporous AuPd (AuPdNPore) alloy catalyst showed superior chemoselectivity and high catalytic activity for the direct 1,4-hydrosilylation of the conjugated cyclic enones with hydrosilane in comparison with the monometallic nanoporous Au and Pd catalysts. The enhanced catalytic properties of AuPdNPore arise mainly from the nanoporous structure and the synergistic effect of the AuPd alloy.
Bimetallic AuPd nanoparticles supported on TiO2 are known to catalyze the reduction of NO with CO. Here, we investigated effects addition lanthanum oxide a AuPd/TiO2 catalyst particle size 2.1–2.2 nm. The La2O3 enhanced catalytic activity; for example, at 250 °C, there was 40.9% conversion and 49.3% N2-selectivity AuPd/TiO2, 100% AuPd-La (1:1)/TiO2. temperature requiring dropped from 400 °C 200...
In this study, irregularly shaped, concave cuboidal Au@AuPd nanoparticles (ISCC-Au@AuPd NPs) with high-index facets were synthesized via Pd overgrowth on pre-formed ISCC-Au NPs with a concentration of Pd precursors as low as 2%. The AuPd alloy nature of the resulting shells was confirmed by X-ray photoelectron spectroscopy, cyclic voltammogram analysis, and energy dispersive X-ray spectroscopy....
In this study, functionalized bimetallic Au-Pd on multi-walled carbon nanotubes (AuPd/MWCNT) are prepared and their application as electrochemical sensor materials for dopamine detection is explored. Furthermore, the as-prepared composite identified using X-ray diffraction (XRD), scanning electron microscope (SEM), transmission (TEM), photoelectron spectrometer (XPS). addition, experimental res...
