We present an electronic structure study of the quasi-one-dimensional chalcogenide BaFe${}_{2}$Se${}_{3}$ using resonant inelastic x-ray scattering (RIXS) at the Fe ${L}_{3}$ edge. In addition to broad spectral contributions from fluorescence, sharp peaks are seen at the low-energy end of the spectra, suggesting the c…
Self-assembled particulate films with a uniform structure over a large area were prepared from La-SrTiO3 nanocubes for thermoelectric applications. UV irradiation was used to assist the formation of particulate film for decomposition of the organic phase in situ to obtain a mechanically robust structure at high temper…
We investigate orientation and lateral ordering of poly(styrene- block -methyl methacrylate) (PS- b -PMMA) diblock copolymer (diBCP) thin films placed on ordered nanoparticle (NP) monolayers. The densely packed NP monolayers were prepared on silicon substrates with the Langmuir–Blodgett (LB) deposition technique. The…
A well-defined cyclobis(paraquat-p-phenylene) (CBPQT4+) end-functionalized poly(n-butyl acrylate) 3 was prepared via RAFT polymerization using a new trithiocarbonate CBPQT4+ derivative 2 as a reversible chain transfer agent. We have shown that the electron-poor CBPQT4+ moiety at the α-chain-end could be specifically m…
The reaction of N-methydiethanolamine (mdeaH2), benzoic acid, FeCl3, and Ln(NO3)3·6H2O or LnCl3·xH2O yields a series of decanuclear coordination clusters, [Ln3Fe7(μ4-O)2(μ3-OH)2(mdea)7(μ-benzoate)4(N3)6]·4MeCN·H2O, where Ln = Gd(III) (1) or Tb(III) (2), and [Er3Fe7(μ4-O)2(μ3-OH)2(mdea)7(μ-benzoate)4(N3)5(MeOH)]Cl·7.5H…
CO adsorption on carbon-supported Pt nanoparticles under operando conditions was studied by quadrupole mass spectrometry and diffuse reflectance infrared fourier transform spectroscopy (DRIFTS). The Pt catalyst was also studied by high-resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectrosco…
The confined and fractional crystallization behavior of poly(ethylene oxide)(PEO) in miscible poly(butylene succinate)(PBS)/PEO blends has been investigated. Both nucleation and growth of PEO crystals through the two-step crystallization process were significantly influenced by the morphology of pre-existed PBS spheru…
In 2010, the Journal of Internal Medicine published a collection of review articles on the application of nanotechnologies in regenerative medicine and drug delivery (1 and references therein). The series also included reviews on nanotoxicology. Toxicology or safety assessment is certainly an integral part of any new…
The existence of a free energy barrier, which prohibits the upward motion of retracted molecules into the surface region of starlike polymer brushes, is analyzed through molecular dynamics simulations in good solvent. This barrier emerges at moderate and high grafting densities, as a result of a density-discontinuity…
This article proposes a simple and sensitive approach for the preconcentration and determination of carboxylated single-walled carbon nanotubes (c-SWNTs) in environmental samples using membranes modified with multiwalled carbon nanotubes (MWNTs). The method is based on the preconcentration of c-SWNTs and their direct…
This review summarizes the capabilities and recent developments of nanoporous polymeric template systems directly supported on different substrates for the confined growth of epitaxial ferromagnetic complex oxide 1D nanostructures. In particular, we describe the versatility and potentiality of chemical solutions combi…
The thermal transport properties of hybrid graphene/h-BN heterostructures are investigated using atomistic simulations. While the thermal conductivity is observed to be significantly limited perpendicular to the graphene/h-BN interface, it is tunable via a composition parallel to the interface. In particular we show t…
A diblock copolymer of crystalline polyethylene (PE) and amorphous poly(methyl methacrylate) (PMMA), PE 69 - b -PMMA 92, was synthesized; this polymer is thermally stable up to 270 °C. The morphological structures of thermally annealed nanoscale thin films of the copolymer were investigated in detail at various temper…
To investigate the factors influencing the luminescent properties of polymetallic cycloplatinated complexes a detailed study of the photophysical and structural properties of the heteronuclear complexes [Pt2Me2(bhq)2(μ-dppy)2Ag2(μ-acetone)](BF4)2, 2, [PtMe(bhq)(dppy)Tl]PF6, 3, and [Pt2Me2(bhq)2(dppy)2Tl]PF6, 4, [bhq =…
Dielectric susceptibility spectra of six chemically similar organic phosphate glass formers are analyzed in order to elucidate the spectral evolution of a multitude of secondary (β) relaxation processes dominating the dielectric loss below the glass transition temperature T(g). By doing the spectral analysis we forgo…
In this study, we investigate the electronic and magnetic properties of Rb${}_{0.77}$Fe${}_{1.61}$Se${}_{2}$ (${T}_{\mathrm{c}}\phantom{\rule{0.16em}{0ex}}$ $=$ 32.6 K) in normal and superconducting states by means of photoemission and $\ensuremath{\mu}$SR spectroscopies as well as band-structure calculations. We demo…
Gold nanoparticles with suitable surface functionalities have been widely used as a versatile nanobioplatform. However, functionalized gold nanoparticles using thiol-terminated ligands have a tendency to aggregate, particularly in many enzymatic reaction buffers containing biological thiols, because of ligand exchange…
The 9,10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene‐10‐oxide (DOPO) polymers, melamine polymers, and DOPO‐melamine copolymers have been successfully synthesized, and their flame retarding properties have also been investigated by blending with polypropylene (PP)/styrene‐ethylene‐butylene‐styrene (SEBS) alloys. Experimental…
The interaction between surfactant-coated graphenes plays a critical role in the performance of surfactant-stabilized graphene dispersion. Herein, we quantified the interaction by simulating the potential of mean force (PMF) between two graphenes encapsulated in sodium dodecyl sulfate (SDS) surfactant micelles. It is…
Hyperbranched azide- and alkyne-functionalized poly(isobutylene)s (PIBs, Mn = 25 200–35 400 g mol−1) suitable for crosslinking at room temperature via the copper-catalyzed alkyne–azide “click” cycloaddition reaction (CuAAC) are reported, aiming at the design of improved crosslinking reactions for novel self-healing ma…
