Co- and Al-modified zeolites (Al-Co-ZSM-5) were prepared by solid-state ion exchange with cobalt acetate or chloride, followed by AlCl3 immobilization from anhydrous toluene solution. Based on data from XRD, X-ray absorption (XANES/EXAFS), X-ray photoelectron spectroscopy and DRIFT spectral studies of adsorbed probe m…
Photoluminescent carbon dots (CDs) derived from chondroitin sulfate (CS) showing multifunctional behavior: cell imaging and cell proliferative responses.
PdCu alloy nanaoparticles (with sizes of <italic>ca.</italic> 4.5 nm) have been synthesized by a one-step electrochemical process on composite films constructed from functionalized graphene (GN) and H <sub>3</sub> PMo <sub>12</sub> O <sub>40</sub> (PMo <sub>12</sub> ) by LBL assembly.
The concomitant substitution of Sr by La and O by N in Sr <sub>2</sub> SiO <sub>4</sub> :Eu <sup>2+</sup> or Ce <sup>3+</sup> produces new luminescent materials with a wide range of emission colours tuned by La/N content.
The γirradiation increases the modulus and strength, decreases the melting point of poly( <sc>l</sc> -lactide) during sterilization. The functionalized carbon nanotubes accelerate the irradiation effect on mechanical and thermal properties of poly( <sc>l</sc> -lactide).
Novel 0.38BMT–0.62PbT single crystals with high <italic>T</italic> <sub>c</sub> , as well as good and temperature-stable piezoelectric properties have been grown by a flux method.
Highly permeable alumina membrane has been prepared <italic>via</italic> wet film phase inversion. Orientated microtubular pores formed due to phase inversion of cellulose acetate.
Water-dispersible dual-mode luminescent probes are fabricated by co-assembling down-conversion CdTe and up-conversion NaYF <sub>4</sub> :Yb,Tm(Er) nanoparticles <italic>via</italic> a ligand-exchange strategy.
Self-assembled functional peptide biomaterials are emerging with a wide range of envisioned applications in the field of nanotechnology. Currently, methods and tools have been developed to control and manipulate as well as to explore new properties of self-assembled structures. However, considerably fewer studies are…
The structural chemistry of Group 13 polyoxometalates lags far behind related negatively charged transition metal species and limits the development of advanced materials. A novel heterometallic cluster [Ga2Al18O8(OH)36(H2O)12](8+) (Ga2Al18) has been isolated using a supramolecular approach and structurally characteri…
A difference in 2D-DBAR-ratio curves reveals different vacancy-like defects observed by positron measurements in unexfoliated graphite oxide and exfoliated graphene oxide samples.
A high carrier concentration may be realized by Na or Mn doping. The thermoelectric properties may be improved by tuning the carrier concentration.
Carbon nanomaterials rescued zebrafish embryos from phenanthrene toxicity.
A small diatom with a peculiar shape is often identified as Navicula schmassmannii in samples collected from alpine lakes and the Arctic region. Due to its characteristic outline, it is relatively well-identifiable, but scanning electron microscope (SEM) confirmation is essential for proving species identity. This spe…
A pH-responsive cocktail paclitaxel/doxorubicin nanocapsule with suitable size (around 100 nm), good biocompatibility and good cell targeting is developed <italic>via</italic> the assembly of poly(amino acid) for synergetic chemotherapy of cancers.
The changeable matrix under different calcination temperatures leads to tunable luminescence properties.
(Sn, Sb)/Ni-based catalytic functional layers situated at the anode surface facilitate long-term operation of hydrocarbon-fueled solid oxide fuel cells by inhibiting the carbon from accumulating onto the Ni surface.
Complexes of gadolinium(III) with N-octanoyl-N-methylglucamine (L8) and N-decanoyl-N-methylglucamine (L10) with 1 : 2 stoichiometry were synthesized and characterized by elemental analysis, electrospray ionization-tandem mass spectrometry (ESI-MS), infrared (IR) spectroscopy, and molar conductivity measurements. The t…
Multinozzle electrospinning systems are designed to increase productivity, while near‐field electrospinning (NFES) systems are designed to deposit solid nanofibers in a direct, continuous, and controllable manner. In this paper, several multinozzle NFES setups are tested. The experiment reveals that the deposition dis…
Heat resistant enameled wire that possessed a polyimide-silica hybrid insulation layer prepared using the sol-gel process was prepared. Tetraethoxysilane (TEOS) was hydrolyzed, followed by polycondensation in polyamic acid varnish, and the varnish was then used as an enamel. Conductor wire was coated with the enamel t…
