Density functional theory-based electronic structure calculations are carried out to obtain the geometries corresponding to the lowest three energy values for Tey (y = 2 − 20) clusters. A comparison of the stability from binding energy curve of these clusters with exchange-correlation energy functional approximated within the local density approxim...

Present study reports synthesis of Cd-free core-only and core-shell quantum dots (ZnSe of size 3.60 ± 0.12 nm and [email protected] of size 4.80 ± 0.20 nm) having excellent fluorescent properties, stability, and aqueous solubility. The fluorescence behavior of these quantum dots (QDs) was utilized for cancer cell imaging and their comparative toxicity in ca...

In this paper, a series of BiOCl0.5I0.5/TiO2 photocatalysts were in situ synthesized by a simple mixed solvothermal method with the aid of lactic acid. The structures and morphologies of as-prepared samples were characterized by XRD, SEM, BET, and DRS. The results of visible light degradation for methyl orange (MO) demonstrated that the BiOCl0.5I0....

Nanocomposites of confeito-like Au nanoparticles (CAuNPs) and TiO2 were synthesized under different irradiation conditions (darkness, UV light, and visible light) and time spans by the reaction of a Ti-citrate-peroxo complex with CAuNPs. The TiO2 synthesized under irradiation formed mesoporous films with embedded CAuNPs. The photocatalytic activity...

In this paper, the W18O49 nanospheres (W18O49 NSs) with diameter about 100 nm have been found to exhibit intrinsic peroxidase-like activity, which can catalytically oxidize 3,3′,5,5′-tetramethylbenzidine (TMB) by H2O2 to produce a color reaction. Different from the catalytic behavior of the Fe3O4 particles, the possible catalysis mechanism was nota...

In this paper, single-crystalline hexahedron hematite is successfully obtained by a simple hydrothermal approach with assistance of PVP as surfactant. SEM and XRD results show that the as-obtained α-Fe2O3 has a nanohexahedron shape with high uniformity and high crystallinity. The effects of a few factors influencing the morphology of α-Fe2O3, such ...

In order to have an insight into the internal electric field (IEF) of BiOCl(001), we design a novel wide-spectrum responsive BiOI(010)/BiOCl(001) heterojunction composite by a facile method. The system could shield the photocatalysis of BiOCl(001) under visible light due to its large Eg (3.41 eV), thus specifying role of the BiOCl(001) in BiOI(010)...

Two transport pathways (interendothelial and transendothelial routes) have long been proposed for entry of nanoparticles from the blood circulation into solid tumors. We examine and discuss available evidence supporting interendothelial and transendothelial transport processes and suggest new avenues for re-evaluating these pathways. Understanding ...

YVO4:Yb3+,Er3+; YVO4:Yb3+,Tm3+; and YVO4:Yb3+,Er3+,Tm3+ were all synthesized via sol-gel method with a subsequent thermal treatment. Specifically, YVO4:Yb3+,Er3+,Tm3+ phosphors were prepared with different annealing temperatures to study the influence of temperature. The transmission electron microscope (TEM), scanning electron microscope (SEM), X-...

Mesoporous ordered materials, whose porosity is within the 2–50-nm range, are an ideal host for functional nanoparticles. Mesoporous thin films, in particular, offer a large variety of options for the fabrication of advanced materials and devices based on the host-guest combination of matrix nanoparticles. Nanocomposite mesoporous films embedding m...
