This work reports the synthesis and characterization of thermoresponsive, stretchable, biodegradable and biocompatible poly(glycerol sebacate)-based polyurethane hydrogels.
Herein, we report for the first time the use of bipyridine-based hydrogel for selective and visible detection and absorption of Cd(2+). At low concentrations, hydrogelator 1 was applied for selective detection of Cd(2+) in vitro and in living cells with high sensitivity. In the absence of metal ions, 1 is nonfluoresce…
An investigation on the synthesis, structure and luminescence characteristics of a novel red phosphor NaLa <sub>9</sub> (GeO <sub>4</sub> ) <sub>6</sub> O <sub>2</sub> :Eu <sup>3+</sup> for LEDs and FEDs.
A novel MIPs-based RTP QDs with molecular recognition ability for 2,6-dichlorophenol was successfully synthesized <italic>via</italic> precipitation polymerization.
We report an inverse relationship between the carbon nanotube (CNT) growth rate and the catalyst lifetime by investigating the dependence of growth kinetics for ∼330 CNT forests on the carbon feedstock, carbon concentration, and growth temperature. We found that the increased growth temperature led to increased CNT gr…
Three oxide dispersion strengthened (ODS) Fe–12 wt-%Cr–5 wt-%Al (12 at-%Cr–9·7 at-%Al) alloys were mechanically alloyed with different oxide additions: (1) Y2O3, (2) Y2O3+HfO2 and (3) Y2O3+ZrO2. The as extruded microstructure was characterised including the oxide particle composition and size distribution. The 700°C P…
Ceria nanoparticles with controlled size have been studied as antioxidant agents for the <italic>in vitro</italic> protection of catecholaminergic cells (PC12) exposed to manganese, which is responsible for an occupational form of Parkinson-like disease.
A zeolite membrane was synthesized on the surface of Pd membrane by seed-free hydrothermal synthesis. The zeolite membrane, which was used as an “armor”, offered good protection to the Pd membranes, significantly suppressing hydrogen permeance loss.
Single crystalline copper selenide (Cu2−xSe) nanocrystals (NCs) with well-defined octahedral morphology are successfully synthesized by a colloidal hot-solution injection method from the reaction of anhydrous CuCl with Ph2Se2 under argon flow, in which 1-octadecene (ODE) and oleylamine (OAm) are used as solvent and su…
Flow-synthesis of mesoporous silica allows deliberate and precise control over the size and shapes and enables the preparation of complex microstructures ( <italic>i.e.</italic> , hollow spheres).
Mesoporous self-assembled cobalt oxide (Co3O4) of different shapes was synthesized by a facile soft-chemical process using cobalt nitrate, oxalic acid and phosphoric acid in the presence of cationic templates, cetyltrimethylammonium bromide, 1-butyl-3-methylimidazolium bromide, and pyridinium bromide at 75 °C/2 h foll…
Hexagonal-phase NaYbF4:Er(3+) upconversion nanoparticles (UCNPs) have been synthesized via a co-precipitation method in high-boiling-point solvents, and remarkably enhanced upconversion luminescence, particularly in red emission bands (650-670 nm) in NaYbF4:Er(3+) UCNPs, has been achieved by Mn(2+) doping. The underly…
The effect of vacancies in monolayer MoS2 on the electronic properties of a Ti-MoS2 top contact has been investigated using first-principles calculations. A Mo-vacancy is easier to form than a S-vacancy in a Ti-MoS2 top contact, especially under oxidation conditions. A Mo-vacancy eliminates the Schottky barrier of the…
The orange emissive powders of a boron-containing compound generate red, green, and blue luminescence after compressing, heating, and volatile acid fuming, respectively. Thus, stimulus-induced emissions have been facilely realized based on one organic π-conjugated material for the first time, to the best of our knowle…
Cyclodextrins (CDs) represent the most extensively investigated cyclic molecules due to their wide availability, facile functionalization, unique amphiphilicity and inclusion capacity. The marriage of CD chemistry with polymer science has generated novel biomaterials by integrating supermolecular host-guest chemistry…
In this study, halloysite nanotubes (HNTs) were used to immobilize lysozyme <italic>via</italic> a covalent binding reaction.
The existence of a denser network domain formed by incorporation of filler and its vital role in determining the strain-induced crystallization behavior of nanocomposites is proved by <italic>in situ</italic> synchrotron X-ray diffraction characterization.
The hydrogen desorption properties of MgH <sub>2</sub> are thermodynamically and kinetically improved by the synergistic addition of AlH <sub>3</sub> and CeF <sub>3</sub> .
Europium decorated graphene provides photoluminescence feature changes with an enhancement of blue emission located at 458 nm after thermal reduction.
ACSECM monitored the self-healing process of scratched epoxy resin coatings with hexamethylene diisocyanate trimer microcapsules as functional additives.
