We monitor the process of dedoping in a planar junction between an electrolyte and a conducting polymer using electrochemical impedance spectroscopy performed during moving front measurements. The impedance spectra are consistent with an equivalent circuit of a time varying resistor in parallel with a capacitor. We sh…
The present study reports a new approach for synthesizing (111)In-radiolabeled biocompatible Fe3O4 nanoparticles. Radioactive (111)In is doped in situ into the lattice of Fe3O4 nanoparticles to achieve robust radiolabeling for accurately tracing PEGylated Fe3O4 particles in vivo.
Synthesis and characterization of novel dinuclear magnesium, zinc and aluminum complexes supported by bis(iminopyrrolide) ligands and their catalysis toward the ring-opening polymerization (ROP) of ε-caprolactone (ε-CL) and rac-lactide (rac-LA) were carried out. The ligand precursors [(5-Bu(t)-2-C4H2NH)CH=N(CH2)2]2NH…
Article Nanocellulose/polymer multilayered thin films: tunable architectures towards tailored physical properties was published on January 1, 2014 in the journal Nordic Pulp & Paper Research Journal (volume 29, issue 1).
A review on chemical and physical preparation of platinum nanoparticles and some applications with these nanoparticles is presented. Application perspectives such fields as nano- catalysts, electrical conductivity, optics and nonlinear optics are demonstrated. Different param- eters and condition of various fabricatio…
This manuscript describes the deposition of carbon on the surface of ZnO nanoparticles <italic>via</italic> a simple adsorption and calcination process.
Monodispersed Fe3O4 nanoparticles have been synthesized by a thermal decomposition method based on the seeded-growth technique, achieving size tunable nanoparticles with high crystallinity and high saturation magnetization. EMR spectroscopy becomes a very efficient complementary tool to determine the fine details of s…
Two different zinc oxide nanoparticles, as well as zinc ions, are used to study the cellular responses of the RAW 264 macrophage cell line. A proteomic screen is used to provide a wide view of the molecular effects of zinc, and the most prominent results are cross-validated by targeted studies. Furthermore, the altera…
Production of one dimensional nanomaterials with secondary morphology exhibiting unique functions is challenging. Here we report for the first time that a nanoscale immiscible polymer blend solution electrojet can assemble into ultraporous interweaving microfibers. This intriguingly novel morphology originated from a…
Homotropic/heterotropic allosteric control over the handedness of dipicolylethylenediamine-functionalized perylene bisimide assemblies was obtained with chiral ATP and achiral PPi guests binding.
In previous studies, the effect of the addition of 1 wt% hydrophilic nanoclay on polylactic acid (PLA)/polycaprolactone (PCL)/oil palm mesocarp fiber (OPMF) biocomposites was investigated by tensile properties, thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). The current studies focus on the e…
Hollow nickel-coated microspheres containing Rh nanoparticles (Rh/Ni@SiO <sub>2</sub> ) generate hydrogen (H <sub>2</sub> ) from hydrazine (H <sub>2</sub> NNH <sub>2</sub> ) with over 99% selectivity within 1.5 h at 25 °C.
Controlled synthesis of hollow polymeric nanocapsules has attracted significant attention in a wide range of applications. This paper reports a facile method for the synthesis of hybrid starch nanocapsules decorated with silver nanoparticles using the inverse miniemulsion polyaddition technique. Silver nanoparticles a…
By virtue of its amorphous structure with a short-range order feature, the inorganic nanoporous nickel oxyhydroxide (NiOOH) can reversibly and rapidly switch wettability by alternate treatments of environmental chamber (superhydrophobic) and UV/ozone (superhydrophilic). The switchable mechanism of the NiOOH/Ni(OH)2 pa…
Germanane, a direct band gap, high electron mobility germanium graphane analogue, has attracted considerable interest for optoelectronics. Here, temperature dependent pair distribution function analysis shows, upon annealing, the two-dimensional germanane framework begins to amorphize. The amorphization onset is indep…
We examine the effect of external electric fields on the behavior of colloidal silica rods. We find that the electric fields can be used to induce para-nematic and para-smectic phases, and to reduce the number of defects in smectic phases. At high field strengths, a new crystal structure was observed that consisted of…
Experiment and computer simulations were conducted in order to study the adsorption of the phthalocyanine molecules H2Pc and CuPc on the h-BN/Rh(111) nanomesh. We combine STM investigations with the exploration of the potential energy surface as resulting from density functional theory calculations. Both approaches in…
AgGaS2 (AGS) nanocrystals that exist in the orthorhombic phase were successfully prepared for the first time through a one-pot colloidal synthetic strategy using suitable coordinating solvents. These orthorhombic AGS nanocrystals were found to display great potential in visible-light-driven photocatalysis.
Localized surface plasmon resonance in V <sub>1−x</sub> W <sub>x</sub> O <sub>2</sub> nanoparticles can induce excellent solar regulation efficiency of thermochromic smart windows.
Accumulation of recalcitrant plastics in the environment has become a world-wide problem in today’s societies. Rapid depletion of natural resources for synthetic plastics along with environmental concerns has directed research towards finding alternatives to petroleum-based polymers. Poly(3-hydroxybutyric acid) P(3HB)…
