A novel strategy for surface modification of multi-walled carbon nanotubes (MWCNTs) using reversible addition fragmentation transfer (RAFT) derived pH- and thermo-responsive polymers was developed via a combination of mussel inspired chemistry and a Michael addition reaction. In this procedure, pristine MWCNTs were fi…
Highly dispersed polypyrrole (PPy) is firstly designed for decorating onto the surface of pristine multiwalled carbon nanotubes (CNTs), then used in the facile synthesis of a CNT/PPy core/shell composite, which provides a potential application for further modification as a base-material due to its high dispersibility.…
A series of flame retarding biodegradable polylactic acid composites (FR-PLA) based on aluminum hypophosphite (AHP) and expanded graphite (EG) were prepared by the melt-compounding method. The effect of AHP and EG on the flame retardancy and thermal stability of PLA were investigated by thermogravimetric analysis (TGA…
A high-yielding dispersion of graphene at high concentration in solvent is critical for practical applications. Herein, we demonstrate the formation of a stable dispersion of pristine graphene in ethanol by exfoliating graphite flakes into individual graphene layers using a non-ionic polymer surfactant under bath-type…
Elsewhere, laboratory-scale solar cells have been demonstrated which show clear evidence of the successful exploitation of semiconducting single walled carbon nanotubes (SWNTs) as primary absorbers of sunlight energy. The unique properties of SWNTs may allow for high efficiency solar cell devices however little progre…
We use a newly-developed method to identify local structural motifs in a popular model glassformer, the Kob-Andersen binary Lennard-Jones mixture. By measuring the lifetimes of a zoo of clusters, we find that 11-membered bicapped square antiprisms, denoted as 11A, have longer lifetimes on average than other structures…
According to classic single-chain theories of rubber elasticity such as the affine or phantom models, the length N and the state of stretching R/R0 of network chains are directly reflected in the magnitude of segmental orientation correlations, as quantified by a dynamic order parameter S ∝ R2/N (this relation holds f…
Numerous microorganisms accumulate polyesters classified as polyhydroxyalkanoates (PHAs) as carbon and energy storage material when the growth condition is unfavorable in the presence of excess carbon source. Natural PHAs typically consist of various (R)-hydroxycarboxylic acids, and exhibit different material properti…
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…
