We report on the thermoelectric properties of (Fe2-x-yMy)V1+xAl alloys (M=Ir and Rh) with compositions x=0, 0.02 and 0.05, and y=0-0.10. While a small deviation from the stoichiometric Fe2VAl composition causes an enhancement in the Seebeck coefficient, a slight substitution of Ir or Rh for Fe leads to a further incre…
Chemical bath deposition (CBD) is a commonly used and inexpensive technique to deposit a variety of semiconductor and oxide thin films for a variety of different applications. In this work, a continuous flow microreactor was used to better control the reacting flux present during the CBD reaction by offering a better…
In this paper, the general synthesis of two-dimensional (2D) ordered porous micro/nanostructured arrays by a layer-by-layer strategy based on the 2D colloidal template transfer are systematically studied. Using such a strategy, various 2D ordered porous films including hetero-pore sized, heterostructured and ion-doped…
A pentanuclear complex, [Mo(CN)8{CuL1}2{CuL1(H2O)}2].6H2O 1, and a decanuclear one, [Mo(CN)8{CuL2}3{CuL2(H2O)}]2.10H2O 2, have been obtained following the building-block approach (HL1 and HL2 are tridentate Schiff bases obtained by reacting salicylaldehyde with 2-aminomethyl-pyridine and 2-aminoethyl-pyridine, respect…
The statistical-thermodynamics and kinetics models of atomic ordering in a metal-doped graphene (binary two-dimensional planar graphene-type crystal lattice) at 1/8, 1/4, and 1/2 stoichiometries are proposed. Impossibility of (completely) atomic-ordered distribution at 1/6 and 1/3 stoichiometries is ascertained in a g…
This study demonstrates that realizing the correlation between in situ crystallographic structure modifications of an electrochromic material and its functionality leads to improved performances, which can then contribute to a variety of energy-efficient applications.
Addition of the germene Mes2Ge=CR2 to 1,4-naphthoquinone yields a singular o-quinodimethane which gives Diels-Alder reactions at room temperature and reacts cleanly with oxygen to form an endoperoxide.
The unique possibilities of current–voltage and force-displacement curve recordings and delicate nanomanipulation of individual inorganic nanotubes under the ultimate spatial resolution typical of high-resolution transmission electron microscope are demonstrated. The examples include metal- or ceramic-filled and nitro…
The indium(III) halo-bridged octahedral dimers [InX(2)(L-L)(mu-X)(2)InX(2)(L-L)] (X = Cl: L-L = MeS(CH(2))(2)SMe, MeSe(CH(2))(2)SeMe, (n)BuSe(CH(2))(2)Se(n)Bu), the ionic trans-[InX(2)(L-L)(2)][InX(4)] (X = Cl: L-L = (i)PrS(CH(2))(2)S(i)Pr; X = Br: L-L = MeS(CH(2))(2)SMe, (i)PrS(CH(2))(2)S(i)Pr, MeSe(CH(2))(2)SeMe), c…
Chiral C(2)-symmetric electroactive bis(oxazolines) containing an EDT-TTF (ethylenedithio-tetrathiafulvalene) backbone, as promising multifunctional ligands and precursors for chiral molecular materials, were synthesized and structurally characterized, together with octahedral molybdenum and tungsten carbonyl complexe…
The quinone-methide elimination is a common, efficient methodology used in linkers designed to undergo self-fragmentation. Here, for the first time, we demonstrate this elimination in a pyridine ring system. Under physiological conditions, a compound constructed of a pyridine core, a reporter, and an enzymatic trigger…
An L-glutamide-functionalized tetraphenylporphyrin () has been newly synthesized and its self-assembling behavior in organic solvents is reported. forms nanofibrous assemblies in a dilute solution to show specific induced circular dichroism at the absorption band around the porphyrin moiety. It enables us to observe t…
The present work extends previous efforts using “micro-mixing” fuel injectors operating on hydrogen fuel to elevated pressure and temperature and includes initial evaluation of a second injector concept. A micro-mixing fuel injector consists of multiple, small and closely spaced mixing cups, within which fuel and air…
The oxidation behavior and electrical property of a Ni–Mo–Cr alloy at in a simulated solid oxide fuel cell (SOFC) anode environment (humidified and diluted ) have been studied. The thermally grown oxide scale presents a multilayered structure, which is similar to that formed in air, with densely grown in between an un…
The solidification microstructure, the thermal property, and the hardness were investigated on AZ91D magnesium alloy and on AZ91D magnesium alloy with 20 mass% gadolinium addition. AZ91D and AZ91D + 20 mass% Gd were solidified by the furnace cooling technique starting from 700°C in an Ar flow atmosphere. The microstru…
Gd 2 MoO 6 : Eu 3 + nanofibers and nanobelts have been prepared by a combination method of the sol–gel process and electrospinning.

Proteins in thermal equilibrium are associated with conformational distributions rather than single, static structures. Although there are no experimental methods to measure the full protein conformational distribution, several methods exist to probe important aspects. Diffuse X-ray scattering is one such method. We h…
A novel shortfiber composite in which the microscopic advanced fiber reinforcements are coated with radially aligned carbon nanotubes (CNTs) is analyzed in this study. A shear-lag model is developed to analyze the load transferred to such coated fibers from the aligned-CNT reinforced matrix in a hybrid composite appli…
