A micro-tubular type solid oxide fuel cell was prepared by using a NiO-YSZ anode support tube and La 0.9 Sr 0.1 Ga 0.8 Mg 0.2 O 3−δ (LSGM) electrolyte film which was prepared by dip-coating and co-sintering process. Since a large electric resistance loss (IR loss) was observed at the cathode side, LSGM porous layer wa…
The effect of matrix crystallinity on the electrical percolation threshold of melt mixed polymer composites containing 0.5 -5.0 wt% of multiwalled carbon nanotubes (MWCNTs) was investigated on the example of polypropylene (PP). Two different polypropylenes having the same low molecular weight and melt viscosity but di…
The band structures of undoped, N <sub>s</sub> doped, N <sub>s</sub> –F <sub>s</sub> co-doped, N <sub>s</sub> –F <sub>i</sub> co-doped, N <sub>i</sub> –F <sub>s</sub> co-doped and N <sub>i</sub> –F <sub>i</sub> co-doped TiO <sub>2</sub> .
Diamond Like Carbon (DLC) films have several unique characteristics, high-hardness, wear resistances, low friction, and good chemical stability. Thus, their applications are widely spread, for example, automotive and mechanical sliding parts, cutting tools, and molding dies. In this paper, we describe their deposition…
The synthesis of a novel monomer, methacryloyl pyrazole, and its subsequent reaction with diisocyanates to produce thermoresponsive crosslinkers is reported.
Processes based on severe plastic deformation (SPD) that are capable of producing microstructures with sizes on the order of nanometres are gaining importance these days. Their typical limitation is the small volume of the material processed. One of available ways to enhancing the productivity is to combine the CONFOR…
A highly stable ratiometric fluorescence probe based on dual-emission QDs was designed for the visual detection of aspirin in human saliva.
substrate. Moreover, the graphene/BFO hybrid structure may display an outstanding photovoltaic effect due to the combination of the bulk photovoltaic effect of the BFO substrate and the optical transparency of the graphene electrode.
Red light emission from CaGd <sub>2</sub> (MoO <sub>4</sub> ) <sub>4</sub> :0.06Eu <sup>3+</sup> phosphor by EDTA assisted hydrothermal route at 200 °C for 24 h.
During recent years, MgH 2 has received significant interest as conversion-type anode for Li-ion batteries due to the high theoretical capacity of 2038 mAh/g at ∼0.5 V vs. Li + /Li. However, the practical reversible capacity and the cycle stability are generally poor and vary significantly among literature reports. Th…

As-synthetized single walled carbon nanotubes (SWCNTs) contain both metallic and semiconducting nanotubes. For the electronics, it is desirable to separate semiconducting SWCNTs (s-SWCNTs) from the metallic ones as s-SWCNTs provide desirable electronic properties. Here we test whether ultrapure semi-conducting single-…
Herein, a pH and redox dual-sensitive core-crosslinked targeting nanocarrier was prepared and used for co-delivery of doxorubicin (DOX) and tariquidar (TQR). The nanocarrier not only had excellent stability but also prevented the leakage of the drug in the normal physiological environment efficiently. Meanwhile, the t…
Nitrogen-doped microporous carbon nanofilm/MoS <sub>2</sub> composites (NMC-nanofilm@MoS <sub>2</sub> ) were synthesized by immersing MOP nanofilms in (NH <sub>4</sub> ) <sub>2</sub> MoS <sub>4</sub> methanol solution and a subsequent annealing process.
A gadolinia-doped ceria (GDC) capping layer was fabricated on a metal Pt cathode via a sputtering technique to enhance the thermal stability and oxygen-reduction reaction (ORR) kinetics. By varying the thickness of the GDC thin film on the Pt cathode, we fabricated thermally durable low-temperature solid oxide fuel ce…
Heteropolytungstostannate of [P <sub>2</sub> W <sub>18</sub> O <sub>68</sub> (HOSn <sup>IV</sup> OH) <sub>3</sub> ] <sup>12−</sup> was grafted on amine levels coated magnetic nanoparticles and used as catalysis in the selective oxidation of sulfides and oxidative amination of aldehydes in an aqueous medium.
The thermal transport properties of graphene are strongly influenced by its contact environment and the strength of such interactions can be used to tailor these properties. Here we find that annealing suppresses the basal plane thermal conductivity (κ) of graphene supported on silicon dioxide, due to the increased co…
The present study aimed to investigate the effect of particle size (100, 500 nm), surface charge (cationic, neutral and anionic) and polyethylene glycol (PEG) modification of magnetic liposomes on their interaction with the human intestinal epithelial cell line, Caco-2. The cellular associated amount of all the magnet…
