Multilayer graphene (MLG), obtained by mild sonication of graphite in NMP or pyridine, was fully characterized via atomic force microscopy (AFM), transmission electron microscopy (TEM), Raman spectroscopy and X-ray photoemission spectroscopy (XPS). Then, it was functionalized via 1,3-dipolar cycloaddition with azometh…
Abstract The effect of small additives of manganese, iron, cobalt, and nickel oxides on the oxidation of aluminum powder of ASD-4 grade while heating in air is studied. Composites of Al/MOx were prepared by impregnating the metal powder with saturated solutions of M(HCOO)2 ⋅ 2H2O (M = Mn, Fe, Co, and Ni) formates and…
Ag <sup>+</sup> is released due to a charge transfer process from the triplet state of adsorbed riboflavin to the silver nanoparticles.
and excellent rate capability. The excellent electrochemical performance can be attributed to the heteroatom-doping and hollow carbon nanostructure of the HHCSs electrodes. Heteroatom groups in the HHCSs not only improve the wettability of the carbon surface, but also enhance the capacitance by addition of a pseudocap…
Abstract In order to improve the corrosion resistance and biocompatibility of magnesium alloys, hydroxyapatite (HA) coating with an outer chrysanthemum-like crystals layer and an inner needle-like crystals layer was successfully prepared on fluorine-treated AZ31 magnesium alloy by hydrothermal treatment. The needle-li…
Aluminum oxide and titanium oxide are widely used as catalytic support. Due to their characteristics and properties, they have several applications such as chemical processes, photocatalysis and pollution control. In this work, the catalytic supports of Al2O3 and TiO2 were impregnated with 2% of copper oxide by the me…
exhibit large deviations above 1000 K. We elucidate the physical origins of these deviations via a phonon mode analysis.
High-valence-state Mn( <sc>v</sc> ) oxide Ba <sub>3</sub> Mn <sub>2</sub> O <sub>8</sub> exhibits good performances for the anodic OER on H <sup>+</sup> -SOEC.
Compared with natural leather, microfiber synthetic leather has many excellent properties such as chemical resistance and physical and mechanical properties. However, the preparation of high performance microfiber synthetic leather with excellent water vapor transmission rate, moisture absorption, and wearing comfort…
(100) have been studied as a function of oxygen coverage. The CO oxidation reaction barrier is rather insensitive to the oxygen coverage regardless of the support, indicating a small increase in activity with the number of surface oxygen atoms.
Liposomes are a proposed tool to use for cell and tissue specific drug targeting. Because of their phospholipid membranes and carrying capacity within their spheres, liposomes are of particular interest for clinical applications. Stealth liposomes are especially important for these clinical applications because they a…
% w/v OMt. In addition, light transmission measurements showed that the transmission of the nanoemulsions varied with temperature, and the process was reversible. The mechanisms of these phenomena were analyzed and confirmed by TEM.
) are low in comparison with those for similar systems which is most likely due to the cooperative effect involving the nature of the corresponding cations together with the features of the supramolecular structures of the complexes.
A lanthanide complex sensor <bold>HL–Eu3+</bold> based on an aromatic cyclic polyamine ligand was constructed for <bold>MP</bold> detection.
Proteins and protein complexes with high conformational flexibility participate in a wide range of biological processes. These processes include genome maintenance, gene expression, signal transduction, cell cycle regulation, and many others. Gaining a structural understanding of conformationally flexible proteins and…
Thermal conductivity of single-crystal boron-doped diamonds (BDD) with ∼2 × 10 19 cm −3 (∼120 ppm) and 5 × 10 19 cm −3 (∼300 ppm) boron content was studied by a steady-state method in a temperature range of 20–400 K. The obtained data were analyzed within Callaway model framework. The values of dislocation density obt…
could combine with the surface ligands of AuNCs, accompanied by a reduction in the luminescence intensity of the AuNCs. Therefore, the fluorescence intensity ratio of PFO dots to AuNCs would be related to the concentration of AA. The nanoprobe enabled highly sensitive analysis of AA with a detection limit of 1.9 μM an…
The ability to control the interparticle distance in self-assembled arrays of nanoparticles plays an important role in a large number of applications, which require tunable electronic and photonic properties. Importantly, practical applications in real devices rely on arrays satisfying more stringent requirements of l…
Nanoparticles (NPs) undergo a number of changes in environmental systems which are often influenced by their interaction with natural organic matter (NOM).
The exchange bias effect of LSMO:NiO composite films transforms from in-plane to out-of-plane with the control of the microstructure.
