The goal of this paper is to improve the performance of an electric motor by modifying the geometry of a specific part of the iron core of its rotor. To be more precise, the objective is to smooth the rotation pattern of the rotor. A shape optimization problem is formulated by introducing a tracking-type cost function…
A Gadolinium EDTA chelate displays characteristic isotropic behaviour common of Gd(III) complexes under zero applied magnetic field, and anisotropic behaviour arising from dipolar coupling and weak spin-phonon coupling under an applied magnetic field. This surprising magnetic behaviour for Gd(III) is investigated usin…
Cyclodextrin (CD) capped CdTe quantum dots (QDs) were prepared with uniform dimension (average diameter ∼5 nm) and high quantum yield (ca. 65%). By taking advantage of the inclusion complexation of CD, β-CD-CdTe QDs exhibited strong fluorescence quenching in a linear relationship with the concentration of o-, m- and p…
Combining core annulation and peripheral group modification, we have demonstrated a divergent synthesis of a family of highly functionalized coronene derivatives from a readily accessible dichlorodiazaperylene intermediate. Various reactions, such as aromatic nucleophilic substitution, Kumada coupling and Suzuki coupl…
Aggregation induced emission active tetra(phenyl)ethene units are incorporated into poly( N -isopropyl acrylamide) to be used as a probe for interpenetrating polymer networks.
Halloysite nanotubes are employed as nanocarriers of carvacrol, allowing for its high-temperature melt compounding with polyethylene, and resulting in highly potent antimicrobial films.
Biomolecule-mimicking nitrogen-doped carbon dots (N-Cdots) were synthesized from dopamine by a neutralization heat strategy. Fluorescence imaging of various cells validated their nucleus-staining efficiency. The dopamine-mimicking N-Cdots "trick" nuclear membranes to achieve nuclear localization and imaging.
A conventional melt electrospinning setup usually needs a large, heavy high-voltage power supply and cannot work without a plug (electricity supply). In this article, we report a new melt electrospinning setup based on a small hand-operated Wimshurst generator, which can avoid electrical interference between the high-…
We present here a simple method for the synthesis of core-shell SiO2@LDH (LDH: layered double hydroxide) particles using an in situ co-precipitation method without any pretreatment. The LDH composition, the overall particle size and morphology can be tuned giving new opportunities for the development of novel sorbents…
Magnetite nanoparticles are of great interest for biomedical applications such as contrast agents in MRI, drug delivery, gene therapy and tissue engineering. In this study, in order to obtain nanoparticles with narrow size distribution and united shape, reverse coprecipitation method was done under ultrasound. Structu…
Glutathione-capped Pd nanoparticles with a size of 1.4-3.5 nm are facilely synthesized for peroxidase nanomimetics. The molar ratio of [Na2PdCl4]/[GSH] greatly affects the physicochemical properties including particle sizes, surface charge states and enzymatic activities. The most efficient Pd-based nanozyme, consisti…
In recent years, considerable efforts have been devoted to the construction of efficient enzyme mimetics, which have significant advantages of simple synthesis and good stability.
Graphene, a single layer of carbon atoms arranged in an aromatic hexagonal lattice, has recently drawn attention as a potential coating material due to its impermeability, thermodynamic stability, transparency and flexibility. Here, the effectiveness of a model system, a graphene covered Pt(100) surface, for studying…
Ideal drug delivery systems should have prolonged circulation in blood, high accumulation in tumors with fast cellular uptake and burst drug release in cancer cells. Herein, a pH-sensitive small-molecule phospholipid prodrug based on phosphorylcholine (PC) was designed to overcome these challenges. The prodrug was syn…
oxidation, heating in air and grafting with a phosphorylcholine copolymer bearing active ester groups. The modified surfaces are characterized by X-ray photoelectron spectroscopy (XPS) and attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy measurements. Interestingly, all the treatments hel…
Fe 3 O 4 @PEI@Ag microspheres as active substrates for SERS-based sandwich assay.
-macromolecule complex and applied in dual emission fluorescent sensors for detection of Bacillus anthracis spores. The Eu-GQD sensors exhibited a morphology of ultrafine particles, increased surface-to-volume ratio, enhanced dispersibility, and extraordinary sensitivity. The 3 nm Eu-GQDs showed three emission bands,…
Effect of phosphonium ionic liquids on the morphologies of PBAT/PLA blends.
A novel rate-dependent and self-healing conductive composite with well defined shear stiffening (S-ST) effect was facilely fabricated by dispersing the multi-walled carbon nanotube (MWCNT) into a shear stiffening polymer matrix.
A bio-based nickel alginate film and copper alginate film were prepared via a facile ion exchange and casting approach. The addition of nickel ions obviously improved the flame retardancy of alginate.
