Halogen ions (I(-), Br(-), Cl(-)) were added into a colloidal solution of CdSe and PbS quantum dots (QDs) to form QDs capped with these inorganic ligands. Halogen ions attached to QDs through electrostatic interactions and the varying coordination strength between the inorganic ligands and QDs led to different degrees…
A hierarchically ordered 4,4′-biphenylene-bridged mesoporous organosilica framework (Bp-PMO) has been synthesized with the aim of using it as a new hybrid host for LnIII ions. A series of novel organic–inorganic luminescent hybrid materials have been obtained by covalently linking LnIII complexes (Ln = Eu, Gd, Tb, Er,…
A cold water soluble, biobased polymer derived from autoxidized soya oil has been described. Oxidized soya oil polymer was obtained by exposure to air under daylight at room temperature. The thickness of the soya oil at the beginning of the reaction and the oxidation time adversely influenced the molecular weight of t…
Solvent recovery is a big challenge for industrial-level production of ultrathin fibers by solution electrospinning because more than 70 wt% of the precursor solution is volatilizable organic solvent. In this paper, we report an interesting solventless electrospinning technique for the fabrication of poly(ethyl-2-cyan…
The healing efficacy of solution-based healing agents for a furan-functionalized epoxy–amine thermoset was investigated. In particular the effects of multimaleimide (MMI) structure and solvent type on healing behaviour were explored. Two major modes of healing are observed: Diels–Alder bonding across the crack surface…
In this work we reported an enzyme-assisted nanoparticle crosslinking (EANC) strategy to enhance the mechanical stability of peptide-based supramolecular hydrogels by more than 3000 times.
Triptycene-derived macrotricyclic polyether was proved to be an efficient “molecular glue” for cross-linking the copolymer containing dibenzylammonium salts to form supramolecular polymer networks via host–guest complexation, which was evidenced by 1H NMR spectroscopy, solution viscometry, and formation of transparent…
Single-crystal strontium titanate (SrTiO3) nanosheets have been synthesized via a solvothermal reaction route with ethylene glycol (EG) as reaction medium solvent. The as-synthesized SrTiO3 products were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and high resolu…
This work deals with the vibrational spectroscopy of O-Anisic acid (OAA) and Anisic acid (AA). The fundamental vibrational frequencies and intensity of vibrational bands were evaluated using density functional theory (DFT) with standard B3LYP/6-31G** method and basis set combinations. The vibrational spectra were inte…
Periodic density functional theory (DFT) calculations have been performed to systematically investigate the effect of reaction intermediate on catalytic activity for hydrazine (N2H4) decomposition on Rh(111). Reaction mechanisms via intramolecular and NH2-assisted N2H4 decompositions are comparatively analyzed, includ…
Magnesium alloys containing long-period-stacking ordered (LPSO) phases have attracted considerable attention because they have been reported to exhibit excellent mechanical properties, including high strength and reasonable ductility. It is thought that the LPSO phase plays a critical role in producing these favorable…
A novel polyelectrolyte nanocapsule system composed of biopolymers, chitosan and heparin has been fabricated by the layer-by-layer technique on silica nanoparticles followed by dissolution of the silica core. The nanocapsules were of the size range 200 ± 20 nm and loaded with the positively charged anticancer drug dox…
Water disinfection has attracted the attention of scientists worldwide due to water scarcity. The most significant challenges are determining how to achieve proper disinfection without producing harmful byproducts obtained usually using conventional chemical disinfectants and developing new point-of-use methods for th…
Nano-gold (sub-5 nm)@mesoporous-silica (m-SiO2) core-shell nanospheres with controlled size and core number were prepared via a soft-templated method. The single-core Au@m-SiO2 particles showed great sintering-resistance at 750 °C and kept high catalytic activity for CO oxidation after the treatment.
A new noncentrosymmetric alkaline earth metal halide borate, BaClBF4, has been synthesized with crystal size up to 6 mm × 6 mm × 3 mm via the hydrothermal method at 200 °C. The crystal structure can be described as an alternate stacking of cationic [Ba2Cl2]2+ layers with anionic [BF4]− layers along the b direction, an…
A facile and robust strategy for creating micropatterned polymer brushes via the combination of a micro-contact printing (μCP) induced supramolecular self-assembled photoactive surface with subsequent self-initiated photografting and photopolymerization (SIPGP) is reported. The results contribute to polymeric function…
We report an inverted structure of quantum-dot light emitting diodes (QLEDs) with cesium carbonate (Cs2CO3) doped aluminum-zinc-oxide (AZO) as the cathode buffer. The Cs2CO3 doped AZO with Cs2CO3 blending ratios (AZO : Cs2CO3) from 4 : 1 to 2 : 1 was used as an electron transport layer in QLEDs. It is found that the c…
Size-tunable crystalline core-crystalline shell Zn2GeO4 nanorods were synthesized via a facile hydrothermal reaction. High purity Zn2GeO4 nanorods were obtained at pH = 7. The length of Zn2GeO4 nanorods (L = 50-100 nm) can be controlled through a one-step process, while micro-sized nanorods with an aspect ratio of the…
The control of the branching in polyglycidols as semibranched alternatives to traditional polyglycidols is presented. The relative abundance of dendritic carbons is lowered by five-fold compared to hyperbranched polyglycidols. It is the first example of tailoring the branching in polyglycidol and creating protein-glyc…
Graphene oxide (GO) potentially has applications in vacuum microelectronic devices for realization of field emission displays. Graphene and its derivatives are expected to be efficient field emitters due to their unique electrical properties. However, the flat sheet structure of graphene or GO allows electron field em…
