Specific heat spectroscopy was used to study the dynamic glass transition of ultrathin poly(2-vinyl pyridine) films (thicknesses: 405-10 nm). The amplitude and the phase angle of the differential voltage were obtained as a measure of the complex heat capacity. In a traditional data analysis, the dynamic glass transiti…
Original and/or functionalized nanosilica particles with a quoted specific surface area of 100, 300, and 600 m2/g, respectively, were used to investigate the influence of specific surface areas of nanosilica particles on ultradrawing and ultimate tensile properties of ultrahigh molecular weight polyethylene (UHMWPE),…
A 0.7MgH 2 + 0.3TiH 2 mixture was prepared by reactive grinding of Mg and Ti powders under hydrogen and tested as a conversion electrode for lithium-ion batteries.
A record-high efficiency (>10%) was achieved for an n-graphene/p-Si Schottky junction solar cell by using the “sunlight-activated” graphene/TiO x transparent cathode.
Unique aramid fibers with hyperbranched polysiloxane–Ce 0.8 Ca 0.2 O 1.8 hybridized coating were prepared, which have outstanding flame retardancy, tensile properties, surface activity and UV-resistance owing to the nature and synergistic effect of hybrids.
The first example of seedless synthesis of gold nanorods using dopamine as a reducing agent is described in this work.
This paper reports a simple route for the generation of fibrous polyvinyl chloride (PVC) and graphene (GN) fibers (PVC@GN).
Only 2.5 wt% DPPA makes the epoxy resin achieve a V-0 rating in the UL-94 test due to the combination of intumescent charring and the blowing-out effect.
Red-to-blue triplet-triplet annihilation upconversion was obtained in giant unilamellar vesicles. The upconverted light was homogeneously distributed across the membrane and could be utilized for the imaging of individual giant vesicles in three dimensions. These results show the great potential of TTA-UC for imaging…
New NIR emitting materials were found among the lanthanide complexes with 2-(tosylamino)benzylidene-N-benzoylhydrazone. Complexes of Nd(3+), Er(3+) and Yb(3+), as well as Eu(3+), Gd(3+) and Lu(3+), were synthesized for the first time. Owing to the absence of vibration quenching the ytterbium complex was found to exhib…
Ce1-xEuxO2 (0 ≤x≤ 0.3) nanoparticles (NPs) were synthesized by the chemical precipitation method. The microstructures and morphology were characterized by synchrotron X-ray diffraction and high resolution transmission electron microscopy. X-ray absorption near edge structure (XANES) spectra at the Eu M5,4-edge and ato…
The present work demonstrates a facile, one-step electrodeposition approach for the preparation of ultrathin Ni–Co double hydroxide (DH) nanosheets on Ni foam as supercapacitor electrodes.
We report on heterogeneous core/shell CaF2:Yb(3+)/Ho(3+)@NaGdF4 nanocrystals of 17 nm with efficient upconversion (UC) photoluminescence (PL) for in vivo bioimaging. Monodisperse core/shell nanostructures were synthesized using a seed-mediated growth process involving two quite different approaches of liquid-solid-sol…
enhancement cannot only be achieved by an increase of particle/cluster size, but also through the precise control of the surface magnetic properties while constraining the nanomaterial dimensions. These achievements open up new perspectives on the mastered design of magnetic nanoprobes, overcoming the limitations rela…
Herein we present the synthesis and the photophysical evaluation of water-soluble chiral ligands (2·(R,R) and 2·(S,S)) and their application in the formation of lanthanide directed self-assembled structures. These pyridine-2,6-dicarboxylic amide based ligands, possessing two naphthalene moieties as sensitising antenna…
Relying on the role of folate and folate receptors, NPFD nanoparticles tend to selectively discriminate tumor cells from normal cells and enter the cells by clathrin-dependent and receptor-mediated endocytosis.
Esterified cellulose nanocrystals were manufactured via one-pot tandem reactions with DMAP as a catalyst. During the process cellulose nanocrystallization and acetylation occurred simultaneously.
Flame retardancy of flexible polyurethane foams has become an issue due to very severe regulations.
Ru nanoparticles deposited onto cellulose nanocrystals are highly active arene hydrogenation catalysts under mild conditions.
A green fabrication approach has been developed to produce biocompatible and non-cytotoxic cationically modified gelatin nanofibers with enhanced biological performance.
