Controlling the deposition of exotic metals in the seeded growth of multimetal nanostructures is challenging. This work describes a seeded growth method assisted by a mask for synthesis of segmented binary or ternary metal nanostructures. Silica is used as a mask to partially block the surface of a seed and a second m…
Co3 O4 -modified CeO2 (Co/Ce 1:4) was prepared by a combination of sol-gel processing and solvothermal treatment. The distribution of Co was controlled by means of the synthesis protocol to yield three different morphologies, namely, Co3 O4 nanoparticles located on the surface of CeO2 particles, coexistent Co3 O4 and…
C-dot sensitized strong Eu <sup>3+</sup> luminescence is observed in Eu <sup>3+</sup> -doped LaF <sub>3</sub> –C-dot nanocomposites <italic>via</italic> energy transfer.
Multiphase nano-structured permanent magnets show a high thermal stability of remanence and a high energy product while the amount of rare-earth elements is reduced. Non-zero temperature micromagnetic simulations show that a temperature coefficient of remanence of −0.073%/K and that an energy product greater than 400…
Mn(2+)-activated red phosphor α-LiZnBO3:Mn(2+) was synthesized by solid state reaction. ESR spectra prove that the doped ions are Mn(2+). The doped Mn(2+) ion is inclined to occupy Zn(2+) site, which is a tetrahedral coordination. The diffuse reflection spectra indicate that α-LiZnBO3:Mn(2+) has strong absorption in t…
In order to provide thermodynamic data for mixed dibasic acid separation technology, the solubilities of adipic acid (AA) and succinic acid (SA) in glutaric acid (GA) + acetone mixture and GA + n -butanol mixture were measured by dynamic method at atmospheric pressure. The mass fraction of GA ( w GA ) ranged from (0 t…
When vitreous silica is submitted to high pressures under a helium atmosphere, the change in volume observed is much smaller than expected from its elastic properties. It results from helium penetration into the interstitial free volume of the glass network. We present here the results of concurrent spectroscopic expe…
For the first time, a clear and unambiguous rationalization of chirality induction, inversion and subsequent amplification process has been demonstrated for the 1 : 1 sandwich and 2 : 3 host-guest supramolecular complexes consisting of Zn(II) host and chiral diamines as guests that has so far remained the most outstan…
A green and facile approach to produce graphene using an environmentally friendly reagent, namely proanthocyanidin (PC) as a reducing agent was developed. The obtained graphene (PC-rGO) was characterized using Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis and X-ray photoelectro…
Lasing in induced cholesteric liquid crystal (CLC) containing highly photosensitive azo chiral dopant (ChD) and pyrromethene laser dye was investigated. Due to the absence of excitation energy transfer from the dye molecules to the molecules of ChD in such a system, a low lasing threshold was achieved. When using viol…
Core-shell structured Zn2SnO4-carbon microspheres with different carbon contents are prepared by one-pot spray pyrolysis without any further heating process. A Zn2SnO4-carbon composite microsphere is prepared from one droplet containing Zn and Sn salts and polyvinylpyrrolidone (PVP). Melted PVP moves to the outside of…
Recently, water-gated organic field-effect transistors (WGOFET) have been intensively studied for their application in the biological field. Surprisingly, a very limited number of conjugated polymers have been reported so far. Here, we systematically explore a series of polythiophene derivatives, presenting different…
This article summarizes the recent advances of benzothiadiazole (BT)‐containing conjugated polyelectrolytes (CPEs) for biological sensing and imaging. After a brief introduction of the molecular design principles, the application of linear BT‐containing CPEs as multicolor or light‐up probes for visual sensing of biomo…
We report a comparative study of the critical current density (Jc) and vortex pinning among pure and Mn doped KxFe2−ySe2 single crystals. It is found that the Jc values can be greatly improved by Mn doping and post-quenching treatment when comparing to pristine pure sample. In contrast to pure samples, an anomalous se…
Abstract Spatial control over the self‐assembly of synthetic molecular fibers through the use of light‐switchable catalysts can lead to the controlled formation of micropatterns made up of hydrogel structures. A photochromic switch, capable of reversibly releasing a proton upon irradiation, can act as a catalyst for i…
Superhydrophobic nanocalcite crystals were prepared via an adjusted aqueous reaction of CaO, CO2 gas and sodium oleate. Box–Behnken design was used to optimize the preparation parameters such as CaO concentration, CO2 gas flow rate and surfactant concentration. The results revealed that the produced CaCO3 is indexed t…
High-dielectric constant materials are critical for numerous applications such as photovoltaics, photonics, transistors, and capacitors. There are numerous polymers used as dielectric layers in these applications but can suffer from having a low dielectric constant, small band gap, or ferroelectricity. Here, the struc…
