Preparation and characterization of platinum-based electrocatalysts on multiwalled carbon nanotubes for proton exchange membrane fuel cells
A higher yield of functionalized carbon nanotubes (CNTs) was obtained by treatment of CNTs in HNO3 or H2SO4−K2Cr2O7. The deposition of platinum nanoparticles and nanoclusters on these functionalized… Expand
Synthesis and characterization of PtRu/C catalysts from microemulsions and emulsions
Nanosized PtRu catalysts supported on carbon have been synthesized from inverse microemulsions and emulsions using H2PtCl6 (0.025 M)/RuCl3 (0.025 M)/NaOH (0.025 M) as the aqueous phase, cyclohexane… Expand
Performances of proton exchange membrane fuel cells with alternate membranes
Hydrogen/oxygen proton exchange membrane fuel cells with Nafion, Aciplex, Flemion and Shanghai membranes have been investigated. The membrane performance is closely related to the chemical… Expand
Replica exchange molecular dynamics of the thermodynamics of fibril growth of Alzheimer's Aβ42 peptide.
The growth of amyloid fibrils is studied by replica exchange molecular dynamics in an implicit solvent. Our data indicate that extremely long simulation times (at least a few hundred ns) are… Expand
Temporal Patterns of Shrub Vegetation and Variation with Precipitation in Gurbantunggut Desert, Central Asia
The relationship between shrub vegetation and precipitation is one important component of desert vegetation responses to climate change, but it has not been understood completely because of its… Expand
Reversible self-assembly of superstructured networks
Chemically reversible hydrogels The dynamic reorganization of some cellular biopolymers in response to signals has inspired efforts to create artificial materials with similar properties. Freeman et… Expand
Interactions between Membranes and "Metaphilic" Polypeptide Architectures with Diverse Side-Chain Populations.
At physiological conditions, most proteins or peptides can fold into relatively stable structures that present on their molecular surfaces specific chemical patterns partially smeared out by thermal… Expand
Self-assembled gold nanoclusters for fluorescence turn-on and colorimetric dual-readout detection of alkaline phosphatase activity via DCIP-mediated fluorescence resonance energy transfer.
We present a fluorescence turn-on and colorimetric dual-readout sensing system for the sensitive detection of alkaline phosphatase (ALP) activity via self-assembled gold nanoclusters (AuNCs) based on… Expand
Surfactant Adsorption in Surfactant-Polymer Flooding for Carbonate Reservoirs
Catalytic hydrogenation of benzaldehydes over platinum nanoparticles immobilized on magnesium aluminate spinel under mild conditions
Platinum nanoparticles, synthesized via ethanol reduction of hexachloroplatinic acid in the presence of poly-(N-vinyl-2-pyrrolidone), were anchored on magnesium aluminate spinel using a colloidal… Expand
