Ultrafine Mg/Al hydrotalcite (MHT) nanoparticles were prepared using a new method in a rotating packed bed (RPB). The MHT nanoparticles were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), transmission electron microscopy (TEM), selected-area elect…
Two anionic complexes [Er(EDTA)(H2O)2](-) and [Er(EDTA)(H2O)3](-) were obtained in the form of the following compounds: [C(NH2)3]2[Er(EDTA)(H2O)2]ClO4·6H2O () and Na[Er(EDTA)(H2O)3]·5H2O (), respectively. The UV-vis-NIR absorption spectra of both monocrystals were measured at room temperature and at 4.2 K. The influen…
The aim of this study was to unveil the mechanism by which aligned nanofibers influence neuronal differentiation. PC12 cells were seeded on three different poly(L-lactic acid) (PLLA) substrates (PLLA films (control), electrospun PLLA random nanofibers (RF) and electrospun PLLA aligned nanofibers (AF)). Subsequently, c…
The inhibition effect of mimosa extract on the corrosion of AA6060 aluminum alloy in acid rain solution was investigated by electrochemical impedance spectroscopy and dynamic electrochemical impedance spectroscopy (DEIS). All the studied electrochemical parameters showed good corrosion inhibitive characteristics with…
Abstract To investigate magnetostructural relationships in colloidal magnetite (Fe3O4) nanoparticles (NPs) at high temperature (300–900 K), we measured the temperature dependence of magnetization (M) of oleate-capped magnetite NPs ca. 20 nm in size. Magnetometry revealed an unusual irreversible high-temperature depend…
Trivalent dysprosium-doped Lu3Ga5O12 nano-garnets have been prepared by sol-gel method and characterized by X-ray powder diffraction, high-resolution transmission electron microscopy, dynamic light scattering, and laser excited spectroscopy. Under a cw 457 nm laser excitation, the white luminescence properties of Lu3G…
Fluorine-substituted Mg(BH 4 ) 2 ·2NH 3 possesses significantly improved dehydrogenation properties.
Oxidative desulfurization and alkene epoxidation proceed in heptane–water biphasic system through facile phase transfer of POM by amine terminated oligomer.
Cavinula Mann & Stickle is small genus presently comprising 25 taxa distinguished by the linear to round-elliptical valve shape, uniseriate striae, presence of nodules and distinctive terminal pores. Most often the species from the genus have been reported from colder northern or alpine oligotrophic aquatic systems, o…
Highly selective synthesis of methyl esters can be achieved by oxidative coupling of methanol and aldehydes (acetaldehyde, butyraldehyde) under mild conditions using unsupported nanoporous gold catalysts over a wide pressure range (from 10 −9 Torr to 1 atm).
Although superparamagnetic iron oxide (SPIO) nanoparticles have been developed as a contrast agent for magnetic resonance imaging (MRI), acute iron overload due to the persistently high retention of SPIOs in the liver and spleen that are slowly converted to ferroproteins is a serious safety concern. Here, we report th…
Extensive numerical solutions of the hypernetted-chain (HNC) and Rogers-Young (RY) integral equations are presented for the pair structure of a system of two coupled replicae (1 and 2) of a "soft-sphere" fluid of atoms interacting via an inverse-12 pair potential. In the limit of vanishing inter-replica coupling ɛ12,…
The strategy of suppressing grain growth by dispersing nanoscale particles that pin the grain boundaries is demonstrated in a nanocrystalline thermoelectric compound. Yttria nanoparticles that were incorporated by mechanical alloying enabled nanocrystalline (i.e., d < 100 nm) Bi2Te3 to be retained up to a homologous t…
PbS colloidal quantum dot (CQD)‐based depleted bulk‐heterojunction solar cells were constructed, using the 1.2 μm thick nanowire array infiltrated with PbS QDs bearing Br ligands. The long‐term stability tests were performed on the solar cells without encapsulation in air under continuous light soaking using a Xe lamp…
In the present work electrically conductive, flexible, lightweight carbon sponge materials derived from open-pore structure melamine foams are studied and explored. Hydrophobic and hydrophilic surface properties - depending on the chosen treatment conditions - allow the separation and storage of liquid chemical compou…
Abstract Herein, we report a rational synthetic access to dinuclear CuII complexes with radical monocationic guanidine ligands. The starting point was the first directed synthesis of a dinuclear CuII complex of the redox‐active, neutral guanidino‐functionalized aromatic (GFA) compound 1,2,4,5‐tetrakis(tetramethylguani…
Large‐area periodic defect patterns are produced in smectic A liquid crystals confined between rigid plate electrodes that impose conflicting parallel and normal anchoring conditions, inducing the formation of topological defects. Highly oriented stripe patterns are created in samples thinner than 2 μm due to self‐ass…
Visible light activation of fluorescent Pt( iv )–azide functionalized carbon dots induces targeted cell cytotoxicity comparable with that of cisplatin.
This study is aimed at determining the interfacial adhesion strength (IAS) of kenaf fibres using different chemical treatments in hydrochloric (HCl) and sodium hydroxide (NaOH) with different concentrations. Single fibre pullout tests (SFPT) were carried out for both untreated and treated fibres partially embedded int…
:Yb,Er nanocrystals were used, either spherical particles with a diameter of 14 nm or nanorods with a length of 41 nm and a diameter of 22 nm. After watering pumpkin seedlings (Cucurbita maxima) with aqueous colloidal solutions of the particles, intact nanocrystals in the plants were detected in vivo by exciting their…
