Magnetic and electric properties are investigated for the nanosized YMnO3 samples with different grain sizes (25 nm to 200 nm) synthesized by a modified Pechini method. It shows that magnetic and electric properties are strongly dependent on the grain size. The magnetic characterization indicates that with increasing…
Colloidal ZnO nanocrystals capped with dodecylamine and dissolved in toluene can be charged photochemically to give stable solutions in which electrons are present in the conduction bands of the nanocrystals. These conduction-band electrons are readily monitored by EPR spectroscopy, with g* values that correlate with…
Most research of responsive surfaces mainly focus on the wettability transition on different solid substrate surfaces, but the dynamic properties of the micro/nanostructure-enhanced responsive wettability on microscale pore arrays are lacking and still remain a challenge. Here we report the photocontrollable water per…
The influence of the nature of metal ion, framework type, exchange method and exchange degree, the addition of NO 2 to the gas flow and the introduction of Al, Nb, and Mn on the selective catalytic reduction (SCR) of NO x with ammonia over ZSM-5 and BEA catalysts was studied before and after hydrothermal aging. From t…
The solubilities of ( Z )-2-(2-aminothiazol-4-yl)-2-methoxyiminoacetic acid in water and alcoholic solvents (methanol, ethanol, 1-propanol, glycol) and the combination of water + alcohols (methanol, ethanol, glycol) of binary mixtures have been experimentally measured in the temperature range from (282 to 330) K using…
Nonequilibrium molecular dynamics simulations have been performed to study the anisotropic thermal transport in pentacene crystal. At 300 K, a thermal conductivity of 0.72, 1.1, and 0.61 W/mK is obtained in the direction of reciprocal lattice vectors a *, b *, and c *, respectively, in a perfect crystal with the gener…
The effect of silk protein with different fibroin/sericin compositions on body weight and lipid metabolism in high fat-fed mice was investigated. The animals were given experimental diets for 6 weeks: normal control (NC), high fat (HF) and high fat diet supplemented with F100 (pure fibroin, HF-F100), F81 (81:19 fibroi…
Transition interface path sampling combined with straightforward molecular dynamics simulation was applied to study the mechanism and kinetics of the crystallization of an undercooled 3:1 binary Lennard-Jones mixture with diameter ratio 0.85 and equal interaction strengths. We find that this mixture freezes via the fo…
Abstract We report a novel strategy to prepare supported Pd catalysts for low‐temperature methane combustion. The structure–property relationship of the catalysts was investigated by tuning the shape and crystal planes of supporting Co 3 O 4 nanocrystals. Pd/Co 3 O 4 nanosheets are more reactive than Pd/Co 3 O 4 nanob…
The self-assembly of molecules into desired architectures is currently a challenging subject for the development of supramolecular chemistry. Here we present a facile "breath figure" assembly process through the use of the self-assembled peptide building block diphenylalanine (L-Phe-L-Phe, FF). Macroporous honeycomb s…
We report the assembly of monodisperse colloidosomes containing a wide range of functional nanoparticles in the outer shell using a double emulsion templating method in a microfluidic device. By selecting nanoparticles of specific functionalities, hollow capsules with inert, magnetic, photocatalytic, and potentially b…
In this study, we investigate the growth and internal properties of polyelectrolyte multilayer films made of poly(l-lysine) and hyaluronan (PLL/HA) under pH-amplified conditions, that is, by alternate deposition of PLL at high pH and HA at low pH. We focus especially on the influence of the molecular weight of HA in t…
Au x Pd1−x (x = 0, 0.25, 0.5, 0.75, 1) nanoparticle (NP) catalysts (8–11 nm) were synthesized by a one-pot reaction strategy using colloidal chemistry. XPS depth profiles with variable X-ray energies and scanning transmission electron microscopy (STEM) analyses show that the as-synthesized Au x Pd1−x (x = 0.25 and 0.5…
Summary Effects of glucose syrup (2%, 4%, and 6%) and pectin (0.5%, 1.0%, and 1.5%) concentrations on physicochemical characteristics and sensory acceptability of machine‐formed pineapple leather snack were investigated. Changes in glucose syrup and pectin concentrations significantly affected velocity of forming and…
Here we explicitly present the diffusion coefficients ($D$) and activation energies (${E}_{a}$) of interstitial H in $\ensuremath{\alpha}$-Fe over a temperature range of 100 to 1000 K. These values were predicted by applying path-integral molecular dynamics modeling based on first principles. The obtained $D$ and ${E}…
Geladene Cluster: Ein Hybridsystem aus einwandigen Kohlenstoffnanoröhren (SWNTs) mit individuell oberflächenadsorbierten Polyoxometallat(POM)-Molekülen kann als kathodenaktives Material in wiederaufladbaren Lithiumbatterien eingesetzt werden. Eine so aufgebaute POM/SWNT-Batterie war durch eine sehr hohe Kapazität (>30…
BACKGROUND AND AIMS: Imperforate tracheary elements (ITEs) in wood of vessel-bearing angiosperms may or may not transport water. Despite the significance of hydraulic transport for defining ITE types, the combination of cell structure with water transport visualization in planta has received little attention. This stu…
The simple, template-free, low-temperature, large-scale synthesis of nanostructured CdS with the hexagonal wurtzite phase from bulk cadmium oxide under solid-phase conditions is demonstrated for the first time. The novel approach involves the homogenization of cadmium oxide (CdO) and thiourea in various stoichiometric…
We report on tuning the light absorption properties of Cu 1.97 S nanocrystals upon organization in ordered supercrystal structures. In particular, we show that the weak absorption profile of Cu 1.97 S nanocrystals can be tuned toward the red part of the visible spectrum. We demonstrate that the controlled addition of…
A graphene-based electrochemical sensing platform for sensitive determination of explosive nitroaromatic compounds (NACs) was constructed by means of electrochemical reduction of graphene oxide (GO) on a glassy carbon electrode (GCE). The electrochemically reduced graphene (ER-GO) adhered strongly onto the GCE surface…
