We synthesized Bi/Bi2O3 heterojunction nanoparticles at various substrate temperatures using the pulsed laser deposition (PLD) technique with a pulsed Nd:YAG laser. The Bi/Bi2O3 heterojunction nanoparticles consisted of Bi nanoparticles and Bi2O3 surface layers. The average diameter of the Bi nanoparticles and the thickness of the Bi2O3 surface layer are linearly proportional to the substrate t...

In this research, the influence of Bi nanoparticles addition on the high temperature superconductor BSCCO-2223 was studied. For this purpose, the samples were synthesized by the conventional sol-gel method. Then, the Bi nanoparticles with x= 0.00, 0.03, 0.06, 0.12wt% was added to BSCCO-2223. The structural characterization of all the samples was done by X-ray diffraction pattern (XRD). Also, th...

Three-dimensional Bi(2)WO(6)/TiO(2) hierarchical heterostructures with secondary anatase TiO(2) nanoparticles grown on primary Bi(2)WO(6) microspheres have been successfully obtained by a low temperature hydrothermal method. The hierarchical Bi(2)WO(6)/TiO(2) structures displayed significantly enhanced visible-light-driven photocatalytic activity in comparison to isolated Bi(2)WO(6) microsphere...

a r t i c l e i n f o Keywords: Bi2Te3 Nanorod Nanoparticle Nanoplate Raman TEM High-crystalline 0D, 1D and 2D ultra-small Bi 2 Te 3 nanocrystals were synthesized using the pyrolysis of organ-ometallic compound method. The Bi 2 Te 3 nanocrystals was studied with transmission electron microscopy (TEM). Samples synthesized at 35 °C possessed a dominant morphology of 0D nanoparticles or 1D nanorod...

A partial cation exchange reaction between CdTe nanoparticles and Bi(3+) ions gives rise to spontaneous formation of two-dimensional Bi(2)Te(3)/CdTe nanosheets. The average size and thickness of the nanosheets are around 200 and 6.9 nm, respectively. Both CdTe and Bi(2)Te(3), which are there as the form of nanoparticles with average sizes of 3.4 nm, are found to be homogenously distributed in t...

In situ growth of bismuth (Bi) nanoparticles on bulk SrBi2Ta2O9 (SBT) platelet is achieved by UV light illumination of SBT in aqueous glucose solutions. Interestingly, the as-produced Bi nanoparticles (NPs) are uniformly oriented with the epitaxial relationship of [001]Bi//[110]SBT, appearing as meso-single-crystal phase despite spatial separation between the NPs. Systematic investigations indi...

Semimetal bismuth (Bi), as an emerging non-noble metal-based cocatalyst and plasmonic photocatalyst, has attracted significant attention. In this work, a one-pot solvent-controlled synthesis strategy was utilized for the in situ-deposition of plasmonic Bi nanoparticles onto the surfaces of (BiO)2CO3 microspheres (BOC-WE) using bismuth citrate, sodium carbonate, and ethylene glycol as precursors...

The synthesis of nanoscaled β-Bi(2)O(3) starting from the bismuth oxido clusters [Bi(6)O(4)(OH)(4)](NO(3))(6)·H(2)O, [Bi(22)O(26)(OSiMe(2)(t)Bu)(14)], [Bi(38)O(45)(NO(3))(20)(DMSO)(28)](NO(3))(4)·4DMSO and [Bi(38)O(45)(OMc)(24)(DMSO)(9)]·2DMSO·7H(2)O (OMc = O(2)CC(3)H(5)) under ambient conditions is reported. The metal oxido clusters are regarded as ideal precursors for β-Bi(2)O(3) due to their...

In this review we discuss the development of paramagnetic liposomes incorporating MRI contrast agents and show how these are utilized in cellular imaging in vitro. Bi-functional, bi-modal imaging paramagnetic liposome systems are also described. Next we discuss the upgrading of paramagnetic liposomes into bi-modal imaging neutral nanoparticles for in vivo imaging applications. We discuss the de...
