Abstract Reactions of an LFe III unit with an M(PyA) 3 n − ion prepared in situ, where L represents 1,4,7‐trimethyl‐1,4,7‐triazacyclononane and PyA − is the monoanion of pyridin‐2‐aldoxime, yield heterodinuclear cations of the general formula [LFe III (PyA) 3 M] 2+ , where M = Zn II ( 1 ), Cu II ( 2 ), Ni II ( 3 ), lo…
The structures of self-assembled peptide amphiphiles are studied using empirical force fields and atomistic molecular dynamics calculations. The hydrophilic headgroups of these amphiphiles possess a lower, rigid part and an upper, flexible part. At an appropriate pH large dipoles are found in the flexible part of the…
We describe a new salt-assisted aero-sol-gel approach to produce spherical nanosized mesoporous silica particles. As an alternative to expensive templating mediums in prior works, salt (NaCl) was employed as a templating medium because it is thermally stable, recyclable, and easily leached. Furthermore, we demonstrate…

The oriented crystallization of poly(1,4-butylene succinate) (PBSU) in the oriented blend with poly(vinylidene fluoride) (PVDF) was investigated at various temperatures. Films of the miscible blend with a composition of PBSU/PVDF = 30/70 (wt %) were prepared by solution casting and were subsequently quenched in ice wa…
A structural study of orthorhombic molybdenum trioxide ${\mathrm{MoO}}_{3}$ with a layered structure has been performed using synchrotron-radiation powder diffraction from 110 to 1000 K. ${\mathrm{MoO}}_{3}$ exhibits an anisotropic thermal expansion. With increasing temperature, the lattice expands remarkably along th…
Abstract A novel polyoxometalate compound, [As 8 V 14 O 42 (SO 4 )][Ni(en) 2 ] 3 ·4.5H 2 O ( 1 ), has been synthesized by a hydrothermal method and characterized by X‐ray crystallography, showing that the compound 1 is the first example of a sinusoidal layer structure constructed from polyoxometalates and coordination…
New amphiphilic molecules containing a bioactive peptide or a claw moiety have been prepared in order to obtain mixed micelles as target-specific contrast agents in magnetic resonance imaging. The first molecule, C(18)H(37)CONH(AdOO)(2)-G-CCK8 (C18CCK8), contains a C18 hydrophobic moiety bound to the C-terminal cholec…
Gold-dendrimer nanocomposites were prepared in the presence of poly(amidoamine) (PAMAM) dendrimer (generation 3, 3.5, 5, and 5.5) via reduction of HAuCl4 with sodium borohydride. The average particle size of the gold nanoparticles was independent of the dendrimer concentration, ranging between 3.0 and 4.3 nm in diamet…
When heated, bis-Cu(II) octaphyrin(1.1.1.1.1.1.1.1) is quantitatively split into two Cu(II) porphyrins both in solution and film states, which is accompanied by large absorption spectral changes.

The synthesis of stable and highly luminescent pyridine-, bipyridine-, phenanthroline-, bipyrimidine-, and terpyridine-based ligands bearing one or two 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (bodipy) modules has demonstrated the advantages of three different protocols which have been adapted in light of the chemic…
Particulate composites of lead–zirconate–titanate (PZT) and NiFe 2 O 4 were prepared using conventional ceramic processing. The measured magnetoelectric (ME) response demonstrated strong dependence on the volume fraction of NiFe 2 O 4 , the magnetic field, and the angle between the magnetic field and polarization in t…

This paper offers the first series of state-of-the-art quantum chemical calculations (CASSCF, CASPT2, MS-CASPT2) and analytical models for the well-known problem of quasi-general ferromagnetic coupling in copper-gadolinium complexes. A system chosen from the chemical report of Costes et al. was taken as prototype. At…
Abstract The chemistry and physics of molecule‐based materials are exciting subjects, and due to potential applications this area is being extensively investigated. Considerable effort is currently being made to design and to investigate new materials involving interplay or synergy between multiple physical properties…
X-ray Absorption Near Edge Structure [XANES] of FePt nanoclusters has been studied using a full multiple scattering, self-consistent field [SCF], real-space Green`s function approach realized via the powerful ab initio FEFF8 code. One purpose of our study is to determine the sensitivity of Pt L3 edge with respect to t…
A susceptibility function $χ(L)$ is introduced to quantify some aspects of the intermittent stick-slip dynamics of a rough metallic cylinder of length $L$ on a rough metallic incline submitted to small controlled perturbations and maintained below the angle of repose. This problem is studied from the experimental poin…
Structural and optical properties of MBE-grown GaAs(001) surface have been studied by reflection high-energy electron diffraction and single-wavelength ellipsometry under dynamic conditions of ramp heating after desorption of passivating As-cap-layer with and without As4 beam applied to the surface. For a number metas…
