Carbon nanotubes (CNTs) have been proposed and actively explored as multipurpose innovative carriers for drug delivery and diagnostic applications. Their versatile physicochemical features enable the covalent and noncovalent introduction of several pharmaceutically relevant entities and allow for rational design of no…

Abstract A series of fluorene‐based luminophores containing methacrylic end groups have been prepared and incorporated into uniaxially oriented liquid crystalline films by in situ photopolymerization. Various structural modifications on the 2‐(4‐cyanophenyl)fluorene core, which include alkyl chains at the 9‐position a…

This paper summarizes the characteristics of chromite ore processing residue (COPR) in terms of their chemical compositions, phases, and recycling potential of iron and chromium through preliminary magnetic separation. COPR from nine hazardous waste sites in Hudson County, N.J., were analyzed using nondestructive inst…
High pressure effects on the crystal structure and magnetic state of ${\mathrm{Pr}}_{0.52}{\mathrm{Sr}}_{0.48}\mathrm{Mn}{\mathrm{O}}_{3}$ manganite up to 31 and $4\phantom{\rule{0.3em}{0ex}}\mathrm{GPa}$ have been studied by means of the x-ray and neutron powder diffraction, respectively. At ambient pressure, ${\math…
This study demonstrates the feasibility of using weak−strong polyelectrolyte (PE) blend systems for controlling the composition and thickness of core−shell particles and PE blend capsules. PE blend capsules were prepared from silica sphere templates via the stepwise adsorption of poly(allylamine hydrochloride) at pH 7…
The crystal structure of the Ag(36)Li(64) gamma-brass was determined by analyzing the powder diffraction pattern taken using a synchrotron radiation beam with wavelength 0.50226 A. It turned out that the compound contained 52 atoms in its unit cell with the space group I43m and that the Li atom enters exclusively into…
Abstract Complex metal oxides, such as e.g. perovskite‐type phases are developed as potential functional materials to improve the efficiency of thermoelectric converters. Among those, cobaltates with p‐type conductivity and n‐type manganates are considered for the realisation of a ceramic thermoelectric converter. Sin…
Highly (100)‐ and (110)‐oriented LaNiO 3 (LNO) thin films were successfully prepared on a Si (100) substrate using the chemical solution deposition method. It was somewhat surprising to find that the orientation of LNO films depended on the heating rates of the temperature range of 200°–400°C. The samples with heating…
Abstract In this study, a tribranched, phenylethynyl‐terminated aryl ether compound (Tri‐PE‐PAEK) was synthesized. This novel star‐shaped compound exhibits a good combination of properties, such as a low melting temperature (252 °C) and good solubility in aprotic solvents, as well as a low melt viscosity (0.1 P at 280…
The structure of Pb(1-x)Ba(x)Zr(0.65)Ti(0.35)O(3) (PBZT) ceramic materials with 0.00 < or = x < or = 0.40 was studied using synchrotron X-ray powder diffraction data. According to the Rietveld refinements, the structure of PBZT ceramics with x = 0.00, 0.10 and 0.20 at room temperature was rhombohedral R3c. A phase tra…
Alkynylamidinium groups have been introduced at the beta and meso positions of a nickel(II) porphyrin (PNi(II)) framework. The modification permits the distance between the amidinium-amidine acid-base group and porphyrin to be increased while effectively maintaining pi conjugation between the porphyrin macrocycle and…
A new macrocyclic ligand, L3, has been synthesised, based on the cyclen framework grafted with three phenacyl light-harvesting groups and a C5-alkyl chain bearing a carboxylic acid function as a potential linker for biological material. Acidity constants are determined by spectrophotometric titrations, as well as cond…
A solution processible poly(3-hexylthiophene) derivative containing O 4 -substituted diaminopyrimidine (ODAP) terminated side groups has been prepared by post-polymerization functionalization of the precursor copolymer, namely, regioregular poly(3-hexylthiophene- co -3-(6-bromohexyl)thiophene), with 2,4-diamino-6-hydr…
The ambient pressure fcc phase of $\mathrm{Na}\mathrm{B}{\mathrm{H}}_{4}$ transforms into a tetragonal $P\text{\ensuremath{-}}{42}_{1}c$ near $6\phantom{\rule{0.3em}{0ex}}\mathrm{GPa}$ and then into an orthorhombic $Pnma$ phase above $8\phantom{\rule{0.3em}{0ex}}\mathrm{GPa}$. While the structures of the cubic and tet…
Z‐type hexaferrite with the composition Ba 3 Co 1.4 Cu 0.6 Fe 24 O 41 was studied as a candidate material for low‐temperature cofiring technology. The samples were prepared by solid‐state reaction at 1250°C and sintered and cosintered with Ag at 900°C. Bi 2 O 3 was used as a sintering additive, which was necessary for…
A transcription error in equation (5), containing the procedure to compute the classical turning points, was detected. Please see the PDF for the corrected equation.
Abstract The crystal structures for cis‐ (Ph 2 PCH=CHPPh 2 )(AuI) 2 and trans‐ (Ph 2 PCH=CHPPh 2 )(AuI) 2 are reported. The structure of cis‐ (Ph 2 PCH=CHPPh 2 )(AuI) 2 reveals a short intramolecular Au–Au distance of 2.9526(5) Å, while the structure of trans ‐(Ph 2 PCH=CHPPh 2 )(AuI) 2 shows intermolecular Au–Au dist…
Hexagonal ferrites represent an extensive family of mixed-layer magnetic materials with periods up to 1500 A along the stacking direction, probably constituting the largest unit cells in the inorganic realm. The (TS)(n)T subfamily includes P3m1 and R3m structures that can be derived from Y ferrite Ba(2)M(2)Fe(12)O(22)…
