Nanoparticles are generally dispersed in electrolyte solutions for cell research. They may be aggregated and thus strongly influence the subsequent bio-effects. However, this has been often neglected in nanotoxicity research. In this paper, we selected gold nanoparticles as an example and investigated the role of disp…
A terbium rich orthoborate, LiSrTb <sub>2</sub> (BO <sub>3</sub> ) <sub>3</sub> , shows paramagnetic behavior, and up to 21 isomorphic analogues have been prepared.
Fe–Cu bimetal nanoparticles were prepared by the dual-mode arc-plasma process. The CO oxidation activity of Fe–Cu/CeO <sub>2</sub> was enhanced by thermal aging at 900 °C. CO oxidation over aged Fe–Cu/CeO <sub>2</sub> proceeded <italic>via</italic> the Mars–van Krevelen mechanism.
The Rh shell of the Au/Pt/Rh trimetallic nanoparticles induces a wide variety of interesting surface reactions by allowing the adsorption of amino acids like L-cysteine (L-Cys). We present a snapshot of theoretical and experimental investigation of L-Cys adsorption on the surface of noble trimetallic Au/Pt@Rh colloida…
A new nanoporous porphyrin-based benzimidazole linked polymer, PBILP, was synthesized.
Dye-nanoparticle mixtures hold great promise in biological as well as photonics applications due to their capability to tailor the emission behavior of dye by tuning the nanoparticles parameters. However, as compared to the well-defined dye-nanoparticle distance, studies lack the understanding of homogenous mixtures o…
Synthesis and structural details of enantiomerically pure alkaline earth metal complexes (Mg, Ca, Sr, Ba) supported by chiral phosphinoselenoic amides are reported.
We report the synthesis and applications of a novel poly(dimethylsiloxane- <italic>block</italic> -poly[3-(triisopropyloxysilyl)propyl methacrylate]) (PDMS- <italic>b</italic> -PIPSMA) diblock copolymer.
For carbon nanotubes of sufficiently large diameter at sufficiently low temperature, due to the action of the van der Waals forces, the ground state is a bilayer graphene with closed edges, the so‐called collapsed configuration. Molecular dynamics simulation of collapsed carbon nanotubes is performed. The effect of le…
Supercharged ceria nanoparticles with excellent oxygen storage capacity.
A series of novel organic-inorganic nanoscale layered materials were synthesized by intercalating the Ti-containing Schiff base complex into the interlayer of the ZnM layered double hydroxides (LDHs, M = Al, Cr, Fe, Ce). The hybrid material was further calcined to make metal oxide composites with highly dispersed Ti e…
The different Mg/Zn ratios of (Mg <sub>1−x</sub> Zn <sub>x</sub> ) <sub>2.97</sub> (PO <sub>4</sub> ) <sub>2</sub> :0.03Mn <sup>2+</sup> result in various PL intensities and spectra profiles, which are related to the crystal field strength and local environment of the Mn <sup>2+</sup> ions.
Block-copolymer orientation in thin films is controlled by the complex balance between interfacial free energies, including the inter-block segregation strength, the surface tensions of the blocks, and the relative substrate interactions. While block-copolymer lamellae orient horizontally when there is any preferentia…
We report on a facile mechanochemical preparation route to directly synthesise a highly efficient nanocrystalline BaFBr:Eu <sup>2+</sup> X-ray storage phosphor and its photostimulable luminescence efficiency.
PMMA-transferred graphene provides much larger GERS signal enhancement than TRT-transferred graphene.
Thermal treatment of graphitic carbon nitride (g-CN) in aqueous solutions of tetraethyl ammonium hydroxide at ∼100 °C yields colloidal solutions retaining stability at a CN concentration of up to 50 g L <sup>−1</sup> and upon dilution by a factor of 10 <sup>3</sup> .
ions, can explain the powerful bactericidal activity of Ag-AQCs, extending the knowledge of silver bactericidal properties. Lastly, we highlight the interest of the interaction of Ag clusters with living organisms, an area that should be further explored due to the potential consequences that it might have, both benef…
High-throughput, roll-to-roll growth and transferring of high-quality, large-area chemical vapor deposited (CVD) graphene directly onto a target substrate with a reusable metal catalyst is an enabling technology for flexible optoelectronics. We explore the direct transfer via hot lamination of CVD graphene onto a flex…
The ability to control the local surface plasmonic resonance (LSPR) absorption peaks of silver nanoparticles will greatly broaden the scope of their practical application. Conventional methods tune the LSPR peaks by modifying the shape or size of the silver nanoparticles. Here, we present a novel method to tune the LS…
A new kind of terpyridine-based Ca(2+) sensor TS was designed and studied based on the internal charge transfer (ICT). In the diluted solution state, TS sensed Ca(2+) and Mg(2+) ions among test ions via an "off-on" approach as seen from fluorescence spectra of test ions. Moreover, TS was able to form stable fluorescen…
