In this minireview, we survey recent advances in the synthesis, characterization, and modeling of new oligothiophene-oligopeptide hybrids capable of forming nanostructured fibrillar aggregates in solution and on solid substrates. Compounds of this class are promising for applications because their self-assembly and st…
This study investigated the effect of Co substitution for Ni in Mn 50 Ni 42 Sn 8 alloy with the aim of increasing the magnetic driving force for inducing its martensitic transformation. The martensitic transformation temperatures, enthalpy and entropy changes were found to decrease progressively with increasing Co con…
Abstract A unique heterotrimetallic supramolecular assembly has been obtained by following a modular synthetic strategy based on the use of octacyanomolybdate(IV), manganese(III), and copper(II) complexes as building blocks. From a structural standpoint, single‐crystal X‐ray diffraction reveals the presence of the thr…
By using the spectrometer 4SEASONS installed at the pulse neutron facility of J-PARC, magnetic excitation spectra have been measured for a large single crystal of the Ca–Fe–Pt–As system, which belongs to one of the series of superconducting systems with FeAs planes. The superconducting transition temperature T c was f…
The lower part of polymeric nanopillars is made mechanically stiff by surrounding it with metal, while the top part of the pillars is soft. The metal-shell-free tops of the pillars could be used for fabricating hollow structures or decorated with functional materials. This mechanical reinforcement shows stability agai…
Abstract Unter Verwendung der zwanzig natürlichen Aminosäuren als Grundbausteine haben biologische Systeme während der Jahrmillionen unter evolutionärem und umweltbedingtem Druck stabile und leichte Peptid‐basierte Materialien entwickelt. Diese Materialien übertreffen ihre synthetischen Gegenstücke in mehrfacher Hinsi…
A detailed investigation of the dependence of the efficiency of plasmon-enhanced enzymatic reactions on the distance between silver island films (SIFs) and horse radish peroxidase (HRP) enzyme and on the loading of SIFs on glass surfaces is presented. Three different extent of loading of SIFs on glass slides were used…
Onconase(®) (ONC) is an amphibian member of the pancreatic ribonuclease superfamily that is selectively toxic to tumor cells. It is a much less efficient enzyme than the archetypal ribonuclease A and, in an attempt to gain further insight, we report the first atomic resolution crystal structure of ONC, determined in c…
An organic-inorganic hybridization strategy has been proposed to synthesize polymerizable lipid-based materials for the creation of highly stable lipid-mimetic nanostructures. We employ atomic force microscopy (AFM) to analyze the surface morphology and mechanical property of electrospun cholesteryl-succinyl silane (C…
We fabricate and investigate field-effect transistors in which a light-absorbing photogate modulates the flow of current along the channel. The photogate consists of colloidal quantum dots that efficiently transfer photoelectrons to the channel across a charge-separating (type-II) heterointerface, producing a primary…

A PbS-sensitized photovoltaic photodetector responsive to near-infrared (NIR) light was fabricated by depositing monolayered PbS nanoparticles on a mesoporous TiO(2) (mp-TiO(2)) film via the spin-assisted successive ionic layer adsorption and reaction (SILAR) method. By adjusting the size and morphology of the PbS nan…
Nanostructures are linked to many areas of science and technology. A cornerstone of our current research is the practical development of boron cluster-based, nanostructured Materials-by-Design. It is now possible to imagine and predictably model properties, synthesis procedures, manufacturing processes, and to functio…
Photoluminescence (PL) properties of individual CdSe nanowires with diameters beyond the quantum confinement regime have been studied. A blue-shift in the PL spectra was observed with decreasing nanowire diameter. We attribute the blue-shift to band-filling effect. Carrier density induced by surface vacancy doping and…
We investigate valley-dependent transport through a graphene sheet modulated by both the substrate strain and the fringe field of two parallel ferromagnetic metal (FM) stripes. When the magnetizations of the two FM stripes are switched from the parallel to the antiparallel alignment, the total conductance, valley pola…
Incorporation of nanoparticles during the hierarchical self-assembly of protein-based materials can impart function to the resulting composite materials. Herein we demonstrate that the structure and nanoparticle distribution of composite fibers are sensitive to the method of nanoparticle addition and the physicochemic…
Abstract In this paper we describe the preparation and characterisation, by single‐crystal X‐ray diffraction, of twelve Zr IV /Hf IV complexes based on piperazine or homopiperazine salan ligands. With the piperazine ligands, a mixture of species was observed and various solid‐state structures were isolated. However, w…
Ungewöhnliches Kristallwachstum: Durch Bildung einer einkristallinen Perylen-Phase an polykristallinen Au-Nanopartikelkeimen wurden Kern/Schale-Nanokristalle erzeugt, die wiederum mit Polyanilin(PANI)-Schalen beschichtet wurden. Perylen wird in Gegenwart von Natriumdodecylsulfat(SDS)-Micellen freigesetzt (siehe Schema…
Abstract Soluble N ‐functionalized basic and cationic polysaccharides have been synthesized using polysaccharide phenyl carbonate as a precursor. The products and intermediates were thoroughly characterized by conventional methods. The quaternization of amino intermediates in various conditions was studied. Moreover,…
Single-phase PbPd0.81Co0.19O2 film with a body-centered orthorhombic structure was prepared using the sol-gel spin-coating technique and an oxidation treatment. Film resistivity has a power dependence on temperature. The insulator-metal transition temperature was 358 K, markedly higher than the reported values of simi…
