A computational method for partitioning a charge density grid into Bader volumes is presented which efficient, robust, and scales linearly with the number of points. The algorithm follows steepest ascent paths along gradient from point to until maximum reached. In this paper, we describe how accurate off-lattice can be represented respect This improvement maintains efficient linear scaling an earlier version algorithm, eliminates tendency surfaces aligned directions. As assigns points...
The prevailing view of CO oxidation on gold-titanium oxide (Au/TiO(2)) catalysts is that the reaction occurs metal sites at Au/TiO(2) interface. We observed dual catalytic perimeter 3-nanometer Au particles supported TiO(2) during oxidation. Infrared-kinetic measurements indicate O-O bond scission activated by formation a CO-O(2) complex Ti-Au Density functional theory calculations, which provide activation barriers for and complex, confirm this model as well measured apparent energy 0.16...
We demonstrate that the reduction of p-nitrophenol to p-aminophenol by NaBH4 is catalyzed both monometallic and bimetallic nanoparticles (NPs). also a straightforward precise method for synthesis using poly(amido)amine dendrimers. The resulting dendrimer encapsulated (DENs) are monodisperse, size distribution does not vary with different elemental combinations. Random alloys Pt/Cu, Pd/Cu, Pd/Au, Pt/Au, Au/Cu DENs were synthesized evaluated as catalysts reduction. These combinations chosen in...
Gold (Au) nanoparticles supported on reducible oxides such as TiO2 demonstrate exceptional catalytic activity for a wide range of gas phase oxidation reactions CO oxidation, olefin epoxidation, and water shift catalysis. Scientists have recently shifted their hypotheses the origin reactivity these materials from unique electronic properties under-coordinated Au sites nanometer-sized particles to bifunctional at Au-support interface. In this Account, we summarize our recent experimental...
Bimetallic core-shell nanoparticles are a class of near-surface alloy catalyst for which there is high degree control over size and composition. A challenge theory to understand the relationship between their structure catalytic function provide guidelines design new catalysts that take advantage material properties arising at nanoscale. In this work, we use density functional calculate energetics oxygen dissociative adsorption on 1 nm Pd-shell with series core metals. The barrier reaction...
Trends in oxygen reduction activity of Pd/Cu bimetallic random alloy nanoparticles are determined with calculations binding for a range compositions. A the average is found as Cu added to Pd, indicating an increase catalytic up peak at 1:1 ratio. Calculations show that reduces Pd-O energy and Pd increases Cu-O energy. These changes understood terms charge transfer from Cu, lowering d-band center raising Cu. The occurs because these two effects not equivalent. greater overlap between d-states...
TiO(2)-supported gold nanoparticles exhibit surprising catalytic activity for oxidation reactions compared to noble bulk which is inactive. The localized at the perimeter of Au where atoms are atomically adjacent TiO(2) support. At these dual-catalytic sites an oxygen molecule efficiently activated through chemical bonding both and Ti(4+) sites. A significant inhibition by a factor 22 in CO reaction rate observed 120 K when preoxidized, caused oxygen-induced positive charge produced on...
Abstract: Theranostic nanoparticles with both imaging and therapeutic abilities are highly promising in successful diagnosis treatment of the most devastating cancers. In this study, dual-modal photothermal effect hyaluronan (HA)-modified superparamagnetic iron oxide (HA-SPIONs), which was developed a previous were investigated for CD44 HA receptor-overexpressing breast cancer vitro vivo experiments. Heat is found to be rapidly generated by near-infrared laser range irradiation HA-SPIONs....
The catalytic reaction of H2+O2 over a Au/TiO2 catalyst was studied by transmission IR spectroscopy and DFT calculations. A path O2-assisted H2 dissociation at the dual perimeter site found to proceed through TiOOH intermediate (see scheme). calculated barrier range (0.13–0.25 eV) for sequence low-energy steps agree with experimental Ea 0.22 eV. Detailed facts importance specialist readers are published as "Supporting Information". Such documents peer-reviewed, but not copy-edited or...
We report experimental as well theoretical evidence that suggests Au–CO complex formation upon the exposure of CO to active sites (step edges and threading dislocations) on a Au(111) surface. Room-temperature scanning tunneling microscopy (STM), X-ray photoelectron spectroscopy, transmission infrared density functional theory calculations point migration. STM surface at pressures in range from 10–8 10–4 Torr (dosage up 106 langmuir) indicates Au atom extraction dislocation herringbone...
Infrared (IR) studies of Au/TiO2 catalyst particles indicate that charge transfer from van der Waals-bound donor or acceptor molecules on TiO2 to Au occurs via transport carriers in the semiconductor support. The ΔνCO is shown be proportional polarizability support fully covered with molecules, producing a frequency shift νCO. Charge through associated population electron trap sites bandgap and can independently followed by changes photoluminescence intensity shifts broad IR absorbance...
On-skin dry electronics are critical for stably transmitting vital and various electrophysiological signals diagnostics the human/machine interface, but they limited by intrinsically poor compliance. High signal-to-noise ratio (SNR) long-term monitoring fidelity require electrode to be highly adhesive in compensation maintain conformable contact. However, enlarged force between skin will lead irritant contact with elevated risk of signal distortion contamination caused delamination. Herein,...
Radiation therapy is effective in achieving local control esophageal squamous cell carcinoma; however, changes the tumor microenvironment induced by radiation can also promote metastasis. Dying cells play vital roles promoting survival of living cells; few studies have investigated effects dying on microenvironment. Since myeloid-derived suppressor (MDSCs) and macrophages constitute pre-metastatic niche (PMN), we used a 4-nitroquinoline-1-oxide situ model to investigate irradiation MDSCs...
Expanded polystyrene (EPS) particles are commonly used for thermal insulation in lightweight building materials due to their low density, conductivity, and affordability. However, shortcomings such as hydrophobicity poor fire safety limit the application of EPS. Bio-based flame retardants have been developed use polymer composites renewable, environmentally friendly, non-toxic properties. In this study, improve hydrophilicity resistance EPS particles, phytic acid (PA)/chitosan...
Conventional wound closure methods, including sutures and tissue adhesives, present significant challenges for self-care treatment, particularly in the context of bleeding wounds. Existing stimuli-responsive contractile materials designed autonomous frequently lack sufficient output work density to generate force needed bring edges into proximity or necessitate stimuli that are not compatible with human body. Here, semi-transparent, flexible, water-responsive shrinkable films, composed...
