A broadband direct warm-white-emitting phosphor Sr3Sc(PO4)3:Eu(2+), Mn(2+) (SSP:Eu(2+), Mn(2+)) was prepared by a solid-state reaction. The powder X-ray diffraction data, photoluminescence spectra, fluorescence decay curves, quantum efficiency, and chromaticity coordinates of the obtained phosphors were measured and d…
Carboxylatopillar[5]arene (CP[5]A) functionalized CdTe quantum dots (CP[5]A@QDs) were synthesized via a ligand-exchange method and shown to be very stable in basic aqueous solutions. Significantly, CP[5]As can be modified on the surfaces of QDs to stabilize the photochemical properties of CdTe nanocrystals and serve a…
From our series of studies on the syntheses of polyhedral gold, Cu2O, Ag2O, PbS, Au–Cu2O, and Au–Pd nanocrystals with systematic shape evolution, we have gained important insights into the growth mechanism and factors controlling the particle morphologies. In the formation of metal nanocrystals, dendritic or branched…
A new structure of hierarchically porous graphene–nickel hydroxide (Ni(OH)2) hybrid, which contains both in-plane mesopores and out-of-plane meso/macropores, has been fabricated by a facile one-step method using holey graphene as a framework structure and Ni(OH)2 as a “spacer”. The aforementioned two kinds of pores fa…
Multidrug resistance (MDR) is one of the critical reasons for the failure of cancer chemotherapy. To overcome MDR, we have developed redox-responsive doxorubicin prodrug (DEX-PEI(-SS-DOX)) micelles based on dextran-poly(ethylene imine) copolymers (DEX-PEI). The DEX-PEI(-SS-DOX) conjugates were conveniently prepared by…
A multi-stimuli sensitive shape memory poly(vinyl alcohol)-graft-polyurethane was synthesized. Fourier transform infrared spectroscopy (FT-IR) and proton nuclear magnetic resonance (1H-NMR) confirmed the chemical structure of the material. The material exhibits good water-induced shape memory behavior and a thermally…
Enhanced selectivity and efficacy is important for advanced drug delivery. Herein, a novel type of folic acid conjugated self-assembled layered double hydroxide nanoparticles is reported. These nanoparticles have a drug loading capacity of 27 wt% and are able to enter cell nuclei and dramatically improve the efficacy…
Materials informatics: a 'hot topic' area in materials science, aims to combine traditionally bio-led informatics with computational methodologies, supporting more efficient research by identifying strategies for time- and cost-effective analysis. The discovery and maturation of new materials has been outpaced by the…
The sodium–metal halide (ZEBRA) batteries have been considered as one of the most attractive energy storage systems for stationary and transportation applications. Even though the battery technologies have been widely investigated for a few decades, there is still a need to further improve the battery performance, cos…
Reversibly fluorescent switchable materials have important applications in the fields of ultrahigh-density optical data storage, molecular switches, logic gates, molecular wires, optical/electronic devices, sensors, bioimaging and so on. Some systems have been developed based on smart luminescent polymers and organic…
Over the past years, polymer-based materials have attracted research interest in the field of tissue repair and regeneration. As reported in literature, different injectable systems have been proposed, trying to reduce surgical invasiveness. In a first step of the current research, the rheological and functional featu…
A ternary nanocomposite of graphene/polyaniline (PANI)/porous silica MCM-41 (MCM-41) was prepared by a hydrothermal method. The amount of graphene oxide (GO) in the graphene/PANI/MCM-41 nanocomposite had a strong effect on the supercapacitor performance. The experimental results showed that the specific capacitance of…
Two 3d-4f nanomagnets, [Dy(III)2Cu(II)7] (1) and [Gd(III)6Cu(II)12] (2), are synthesized under a two-step in situ reaction of picolinaldehyde. Not only the final adduct (hemiacetal), but also the intermediate (gem-diol) are "visualized" by X-ray single crystal diffraction. The Dy complex behaves as a single-molecule m…
In this work, we developed an efficient and facile method to fabricate branched polyaniline (PANI)/α-MoO3 organic/inorganic heteronanostructures. Scanning electron and transmission electron microscope measurements showed that PANI nanorods with an average diameter and length of about 55 and 110 nm respectively were gr…
In this work, large-scale three-dimensional dendritic α-Fe which possesses two different faces with uniform width of about 3.0 μm and length of about 9.0 μm was directly synthesized using an electric field-induced and electrochemical reduction method in FeSO4 aqueous solution for the first time. This synthesis method…
The properties of drastically change when matter makes transition from 1D, 2D, 3D, to 0D. The quantum dots (QDs) of strontium oxide (SrO) were synthesized by one pot chemical precipitation method using hexamethylenetetramine (HMT). The radius of SrO QDs was calculated from hyperbolic band model (HBM). The direct and i…
Novel hierarchical wool-ball-like copper sulfide (CuS) microflowers with a three-dimensional (3D) porous framework were successfully synthesized by the direct reaction of copper with sulfur powder using a one-pot in situ growth method at low temperature (60 °C). The CuS microflowers covered firmly the surface of the 3…
A novel quantification approach for tissue imaging using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) based on tissue embedding in cold-curing resins (Technovit 7100) is presented.
