The immobilization of thiol-terminated poly[(methacrylic acid)-ran-(2-methacryloyloxyethyl phosphorylcholine)] (PMAMPC-SH) brushes on gold-coated surface plasmon resonance (SPR) chips was performed using the "grafting to" approach via self-assembly formation. The copolymer brushes provide both functionalizability and…
We demonstrate control and tunability of the exciton fine-structure splitting by properly engineering a nanojunction consisting of a CdSe nanocrystal core and an asymmetric rod-like CdS shell. Samples with small core and/or thick rod diameters exhibit a strongly reduced fine-structure splitting resulting from a reduce…
For exploration of the effects of polyoxometalate on the photoelectrochemical properties of cadmium sulfide (CdS), a composite film of poly(allylamine hydrochloride)-modified CdS (CdS-PAH) and polyoxometalate (K 6 P 2 W 18 O 62 ) has been prepared by the layer-by-layer self-assembly method. The thin film was character…
Porous cubic Cu microparticles were synthesized by a facile solvothermal method using Cu(CH(3)COO)(2)·H(2)O as the Cu precursor and NaOH in a solution containing ethanol, ethylene glycol, and water. The synthesis conditions were investigated and a growth process of porous cubic Cu microparticles was proposed. The cata…
The frequency-dependent dielectric constant, shear and adiabatic bulk moduli, longitudinal thermal expansion coefficient, and longitudinal specific heat have been measured for two van der Waals glass-forming liquids, tetramethyl-tetraphenyl-trisiloxane (DC704) and 5-polyphenyl-4-ether. Within the experimental uncertai…
In this report, the cisplatin (CDDP)-loaded gelatin/poly(acrylic acid) (GEL-PAA) nanoparticles with a spherical shape and drug loading content of 24.6% were prepared. In vivo near-infrared fluorescence (NIRF) imaging and ex vivo gamma scintillation counting analyses reveal that CDDP-loaded GEL-PAA nanoparticles have p…
Abstract Part 1 (see companion paper) of the present study discussed the application of a multimethod approach in characterizing the size of cerium oxide nanoparticles (NPs). However, other properties less routinely investigated, such as shape and morphology, structure, chemical composition, and surface properties, ar…
In this work, we demonstrate that there is a continuum of different formulations for the decomposition of ⟨Ŝ(2)⟩ that fulfills all physical requirements imposed to date. We introduce a new criterion based upon the behavior of single-electron systems to fix the value of the parameter defining that continuum, and thus w…
Optical measurements have been carried out on high-quality BiFeO 3 single crystals in order to show the presence of electronic defect states and calculate the band gap. The photoluminescence spectra show an intense electronic transition peak at a wavelength of 410 nm. This peak is large and asymmetric, indicating the…
A bilayer fish-scale metamaterial is experimentally demonstrated to function as a broad bandpass filter in the terahertz regime. The measured 3 dB-bandwidth for normal incidence is 1.13 THz with a high transmittance. The measured transmission spectrum is described well by a model based on an RLC circuit and multiple r…
Non-doped as well as titanium and lutetium doped zirconia (ZrO2) materials were synthesized via the sol-gel method and structurally characterized with X-ray powder diffraction. The addition of Ti in the zirconia lattice does not change the crystalline structure whilst the Lu doping introduces a small fraction of the t…
In addition to enhancement of the results near the point of application of a concentrated load in the vicinity of nano-size defects, capturing surface effects in small structures, in the framework of second strain gradient elasticity is of particular interest. In this framework, sixteen additional material constants a…
In this paper, we study the kinetics and energetics involved in the nucleation and propagation of and twinning dislocations (TDs) in Mg using atomistic simulations. We demonstrate that for both twins, a 2-layer TD of mixed character nucleates as a result of the interaction of a basal dislocation with a twin boundary.…
Unlike Mn doped quantum dots (d-dots), the emission color of Cu dopant in Cu d-dots is dependent on the nature, size, and composition of host nanocrystals (NCs). The tunable Cu dopant emission has been achieved via tuning the particle size of host NCs in previous reports. In this paper, for the first time we doped Cu…
Plastic deformation in polycrystalline materials involves a complex interaction of dislocations with defects in the lattice. The geometrically necessary component of the dislocation density can be quantified to some extent using data obtained from automated electron backscatter diffraction scans over planar regions or…
In this work, we examine the high-pressure behavior of superhard material candidate WB${}_{4}$ using high-pressure synchrotron x-ray diffraction in a diamond anvil cell up to 58.4 GPa. The zero-pressure bulk modulus, ${K}_{0}$, obtained from fitting the pressure-volume data using the second-order Birch-Murnaghan equat…
Luminescent cyclometalated iridium complexes based on pyridyl appended dipyrrin ligands were prepared and characterized both in the solid state and in solution. The functionalization of the peripheral pyridyl moiety causes dramatic changes on the emission properties of both mono- and hetero- binuclear complexes. A det…
Abstract Boehmite nanoparticles (γ‐AlOOH) have been successfully synthesized by the hydrothermal method at 180 °C using aluminum nitrate, Al(NO 3 ) 3 ·9H 2 O, as the aluminum source and sodium metaborate, NaBO 2 ·4H 2 O, as controlling agent. The size and morphology of boehmite nanoparticles could be controlled by adj…
The mechanism of core/shell formation during sintering in B a T i O 3 ‐based systems was studied in ( M g, Y )‐doped B a T i O 3 . The effect of ball milling time on core size and shell thickness was first observed. The core size was similar irrespective of ball milling time whereas the shell thickness increased with…
A series of new functionalized mono- and dibenzo-appended BODIPY dyes were synthesized from a common tetrahydroisoindole precursor following two different synthetic routes. Route A involved the assembly of the BODIPY core prior to aromatization, while in Route B the aromatization step was performed first. In general,…
