To date, considerable effort has been devoted to determine the potential toxicity of nanoparticles to cells and organisms. However, determining the mechanism of cytotoxicity induced by different types of nanoparticles remains challenging. Herein, typically low toxicity nanomaterials were used as a model to investigate…
We report organic–inorganic hybrid gels composed of polyhedral oligomeric silsesquioxane (POSS)-based network polymers and their variable emission properties depending on the size of coexisting silica particles (SPs).
Convenient and mild syntheses of two europium( <sc>iii</sc> ) complexes, Na[Eu(dipic) <sub>2</sub> ·3H <sub>2</sub> O]·4H <sub>2</sub> O (dipic = dipicolinate anions) and Na[Eu(dipic) <sub>2</sub> ·phen]·H <sub>2</sub> O (phen = 1,10-phenanthroline), were reported.
We present a new family of highly emissive white phosphors.
Response of a 100 mg mL <sup>−1</sup> α-CD/15 mg mL <sup>−1</sup> Tyloxapol hydrogel towards additives, pH, temperature and solvent.
Hybrid inorganic/organic dual columnar materials display aggregation-induced enhanced phosphorescence based on inter-disk Pt–Pt interactions in a fluid state.
We present extensive experimental and theoretical investigations on the structure, phase behavior, dynamics and rheology of model soft-hard colloidal mixtures realized with large, multiarm star polymers as the soft component and smaller, compact stars as the hard one. The number and length of the arms in star polymers…
Developing facile superhydrophobic metal surfaces with good mechanical durability.
Nano-structured spherical micro-granules of core–shell morphology have been realized by utilizing the contrasting interfacial interaction of two different types of nano-particles with liquid solvent.
Here, we report a phosphor ceramic plate (PCP) constructed using Y <sub>3</sub> Al <sub>5</sub> O <sub>12</sub> :Ce <sup>3+</sup> (YAG:Ce) nanoparticles (NPs) with a uniform spherical size distribution for high-power light emitting diode (LED) applications.
Ga-doped ZnO based ultraviolet photodetectors (PDs) were fabricated with a metal–semiconductor–metal structure. The room-temperature operable PDs had 58 mA W <sup>−1</sup> responsivity at zero bias with internal and external quantum efficiency values of ∼22.5 and 37.4%.
Three fluorescent polyimides (PIs) were readily synthesized from the polycondensation of triarylamine-based tetracarboxylic dianhydride monomers with aliphatic diamine. The PL intensity of solid films and nanofibers revealed high PL quantum yields of up to 32% and 35%, respectively.
In this work, a facile one-step solvothermal method with the assistance of hydrochloric acid has been developed to prepare well-dispersed CeO2 hollow nanospheres with high surface areas. The effects of hydrochloric acid on the growth mechanism and the size distribution are investigated in detail. It is found that the…
<italic>In situ</italic> , development of mesocarbon microsphere (MCMS) composites with magnetic Fe <sub>3</sub> O <sub>4</sub> nanoparticles for outstanding electromagnetic (EMI) shielding effectiveness.
Electroactive polymer-peptide conjugates have been synthesized by combining poly(3,4-ethylenedioxythiophene), a polythiophene derivative with outstanding properties, and an Arg-Gly-Asp (RGD)-based peptide in which Gly has been replaced by an exotic amino acid bearing a 3,4-ethylenedioxythiophene ring in the side chain…
We report our extensive attempts and, ultimately, success to produce crack-free, chiral nematic GeO2/cellulose nanocrystal (CNC) composite films with tunable photonic properties from the controlled assembly of germanium(iv) alkoxides with the lyotropic liquid-crystalline CNCs in a mixed solvent of water/DMF. With diff…
Guanidinium octahydrotriborate, with a melting point of <−10 °C, releases >10 wt% high purity hydrogen below 100 °C.
AIE active 9,10-bis( <italic>N</italic> -alkylindole-3-yl-vinyl-2)anthracene homologues ( <bold>IACn</bold> ) could be facilely prepared and exhibit alkyl length-dependent piezofluorochromic properties whose spectral shifts increase with the decrease of <italic>N</italic> -alkyl chain lengths.
Recently, intensive efforts have been focused on the search of novel two-dimensional (2D) materials for memory and spintronic applications.
This work shows that the porosity of conjugated microporous polymers (CMPs) can be controlled by screening the phosphine ligands of palladium catalysts in the Sonogashira coupling of alkyne and halide building blocks.
