ABSTRACT

In it for the long haul: Clusters of Pt nanowires (3D Pt nanoassemblies, Pt NA) serve as an electrocatalyst for low-temperature fuel cells. These Pt nanoassemblies exhibit remarkably high stability following thousands of voltage cycles and good catalytic activity, when compared with a commercial Pt catalyst and 20 % wt Pt catalyst supported on carbon black (20 % Pt/CB).

    • "Silver nanoparticles were found to be best biocide, for example in wound dressings and as an antimicrobial coating on consumer products but the major problems such as aggregation, agglomeration, oxidation and inactivation of silver nanoparticles , numerous preventive measures have been employed. To overcome these issues fabrication and application of porous silver monoliths as biomaterials are currently in great interest because of their good stability, three-dimensional porosity, high aspect ratio, good surface to volume ration, high number of active sites, highly active surface silver atoms, efficient bactericidal activity, good materials for bio-separations, drug delivery and importance in biomedical devices12345678910. In this study, macroporous silver monoliths were tested against two strains of Gram negative pathogens (E. "

    ABSTRACT: Herein we report the facile synthesis of three dimensional macroporous (MP) silver monoliths serving as intelligent biomaterials against Gram negative (Escherichia coli, Salmonella typhimurium) and Gram positive (Bacillus subtilis) bacteria with more efficacy against Gram negative bacteria. The macroporous silver monoliths were examined by Fourier transform infra red (FTIR) spectroscopy, thermogravimetric analysis (TGA), X-ray diffraction (XRD) study, field emission scanning electron microscopy (FESEM), energy dispersion X-ray spectroscopy analysis (EDX) and Brunauer–Emmet–Teller (BET) adsorption technique. From the antibacterial activity results, it was concluded that macroporous silver monoliths can serve as efficient disinfection agents. The enhanced antibacterial properties of macroporous silver monoliths was possibly due to high surface free energy of the surface Ag+ atoms leading to cell membrane damage followed by cell death.

    • "Meantime, all the patterns clearly showed other three main characteristic peaks of face-centered cubic crystalline within 30–80°. For Pd/CNTs and Pt/CNTs, three peaks were observed, which matched well with those of Pd (01-1201) [37] and Pt (04-0802) [38] respectively in the Joint Committee Powder Diffraction Standard. It was noteworthy that the 2h values of the (1 1 1) lattice plane [39] for the Pd 3 Pt/CNTs, PdPt/CNTs and Fig. 1. "

    ABSTRACT: Herein, a facile ultrasonic-assisted strategy was proposed to fabricate the Pd-Pt alloy/multi-walled carbon nanotubes (Pd-Pt/CNTs) nanocomposites. A good number of Pd-Pt alloy nanoparticles with an average of 3.4 ± 0.5 nm were supported on sidewalls of CNTs with uniform distribution. The composition of the Pd-Pt/CNTs nanocomposites could also be easily controlled, which provided a possible approach for the preparation of other architectures with anticipated properties. The Pd-Pt/CNTs nanocomposites were extensively studied by electron microscopy, induced coupled plasma atomic emission spectroscopy, X-ray diffraction, and X-ray photoelectron spectroscopy, and applied for the ethanol and methanol electro-oxidation reaction in alkaline medium. The electrochemical results indicated that the nanocomposites had better electrocatalytic activities and stabilities, showing promising applications for fuel cells.

    ABSTRACT: Well-defined noble metal nanocrystals (NMNCs) of a unique morphology yet a uniform facet have attracted broad interests. In this regard, those with a highly branched architecture have gained particular attention. Most of the currently existing branched NMNCs, however, are enclosed by mixed facets. We now report that branched Au nanoarchitectures could be facilely fabricated by mixing an aqueous solution of KAuCl4, an aqueous dispersion of graphene oxide, and ethanol under ambient conditions. Interestingly, unilike the conventional branched NMNCs, our unique Au nanostructures are predominately enriched with a uniform facet of {111}. Compared to the spherical Au nanostructures exposed with mixed facets, our branched nanospecies of a uniform facet display superior catalytic performances both for the catalytic reduction of 4-nitrophenol and the electrocatalytic oxidation of methanol. Our investigation represents the first example that Au nanostructures simultaneously featured with a highly branched architecture and a uniform crystal facet could be formulated. Our unique Au nanostructures provide a fundamental yet new scientific forum to disclose the correlation between the surface atomic arrangement and the catalytic performances of branched NMNCs.
