This Communication describes the novel isolation with metal elemental control of cobalt hexacyanoferrate/chromate metal coordination polymers, stabilized by stearylamine (Co-Fe/Cr-SA) as a protecting coordination ligand in a reverse micelle technique. Each Co-Fe/Cr-SA can be isolated with high uniformity of particle size and elemental composition, and the… (More)
PtCo alloy nanoparticles with different metal elemental ratios (Pt/Co = 0.9, 1.6, 2.9, and 3.6) were prepared by a novel synthetic approach, using the transformation reaction of platinum(IV)/cobalt tetracyanoplatinate metal coordination nano-polymers (Pt(II)-CN-Pt(IV)/Co)via a H2 gas-phase reduction.
We report a convenient method to synthesize single-crystalline platinum nanowires with high aspect ratio of ca. 2.0 nm diameter by sophisticated and precise control of Pt(0) nuclei and their growth.
Prussian blue nanoparticles (PB NPs), stabilized for the first time by the pi-conjugated polymer poly(4-(2,3-dihydrothieno[3,4-b][1,4]dioxin-2yl-methoxy-1-butanesulfonic acid, potassium salt) (PEDOT-S), demonstrated a novel multiple-color pH-sensing function with a redox reaction based on the electronic interaction between the PB nano-core and the PEDOT-S… (More)
The production of retinol binding protein 4 (RBP4) is higher in adipose tissue in type 2 diabetes. We have found that proteasome subunit beta type 1 (PSMB1) is a transcriptional activator of Rbp4. In the present study, the putative tyrosine phosphorylation site in PSMB1 was mutated to phenylalanine. The mutated form of PSMB1 displayed increased nuclear… (More)
Surface structures of shape-controlled Pt nanoparticles have been estimated using cyclic voltammetry (CV) and infrared reflection absorption spectroscopy (IRAS). Cubic and cuboctahedral Pt nanoparticles are prepared using a capping polymer. These nanoparticles give CVs similar to those of single crystal electrodes of Pt in sulfuric acid solution. The CV of… (More)
A tubular fibre structure with a ca. 9-11 microm outer diameter comprised of FeCo nanoparticle assemblies with an amorphous carbon core was fabricated via reductive thermal decomposition of a cellulose-cobalt hexacyanoferrate (Fe-CN-Co) composite material.
Gold nanoparticles fully coated with discotic liquid crystalline molecules of hexaalkoxy-substituted triphenylene (Au-TP) have been synthesised, the self-assembled structure of which could be controlled (hexagonal or 1D nanochain) just by altering the ratio of methanol to toluene in the solvent.
We describe the self-assembly of gold nanoparticles (Au NPs) protected with newly synthesized discotic liquid crystalline molecules of hexaalkoxy-substituted triphenylene (TP) in mixed toluene/methanol solvent. The stripelike (i.e., 2D consisting of linear 1D in stripe) self-assembly is realized successfully by the aid of pi-pi stacking of TP ligand on Au… (More)
