Manganese doped ferrite (MnxFe3-xO4) nanoparticles with x = 0.29-0.77 were prepared under solvothermal conditions in the presence solely of a polyol using the trivalent manganese and iron acetylacetonates as precursors. In this facile approach, a variety of polyols such as polyethylene glycol (PEG 8000), tetraethylene…
Emitting nanofibers based on tricarbazole derivatives have been fabricated <italic>via</italic> organogelation and used as fluorescence sensors to detect nitroaromatics.
Highly efficient NIR to NIR upconversion in CaMoO <sub>4</sub> :Tm <sup>3+</sup> , Yb <sup>3+</sup> nanocrystals pumped by less than 1 mW laser was achieved for biomedical applications.
The synthesized three-phase heterostructure composite CF/Co <sub>0.2</sub> Fe <sub>2.8</sub> O <sub>4</sub> /PANI shows an excellent EM wave attenuation performance in the K <sub>u</sub> band and the minimum RL values are all lower than −20 dB with an absorber thickness of 3.1–4.1 mm.
Mesoporous carbon nanoparticles (MCNs) with large and adjustable pores have been synthesized by using poly(ethylene oxide)-b-polystyrene (PEO-b-PS) as a template and resorcinol-formaldehyde (RF) as a carbon precursor. The resulting MCNs possess small diameters (100-126 nm) and high BET surface areas (up to 646 m(2) g(…
Site occupancy of Eu <sup>2+</sup> , Eu <sup>3+</sup> , Sm <sup>3+</sup> and Dy <sup>3+</sup> is investigated in Sr <sub>2</sub> SiO <sub>4</sub> using TRFS and EXAFS and complemented by DFT calculations.
Philippe Marcus opened a general discussion of the paper by Roger Newman: Should the passive film not be significantly involved in pit initiation (as you suggest), how would you explain that the time to initiation is very much dependent on the nature of the passive film? Roger Ne
Currently, copper sulfide (CuS) is the most commonly used counter electrode (CE) in high-efficiency quantum dot-sensitized solar cells (QDSSCs) because of its superior electrocatalytic activity in the presence of polysulfide electrolyte. For the first time, CuS thin films were prepared by a facile chemical bath deposi…
delineation of disease through macrophage imaging.
We report on transiently responsive protein-polymer conjugates that temporarily change their protein conformation from the soluble to the particle-like state. 'Grafting-from' RAFT polymerization of a dioxolane-containing acrylamide with a protein macroCTA is used to design polymer-protein conjugates that self-assemble…
Two new iron(II) 1D coordination polymers with spin crossover behaviour were synthesised using 3,3′-azopyridine as bridging axial ligand and N2O2 coordinating Schiff base-like equatorial ligands. The X-ray structures of both complexes were solved revealing very different packing patterns for the two complexes. Magneti…
The controlled release of an anticancer agent from drug nanoparticles could be achieved by varying the linker length of dimeric compounds as prodrug. Notably, the cytotoxicity of the cancer cells was closely related to the release rate of drug compounds. This strategy will lead to the establishment of the novel delive…
Graphite oxide might be a promising adsorbent for adsorption denitrogenation due to its significant amount of oxygen functional groups.
Optically stimulated persistent luminescence was investigated for europium-doped LaAlO3 nanocrystals. This system shows conventional luminescence of both the Eu(3+) line emission and the weak broad-band emission of Eu(2+) upon UV excitation. The persistent luminescence is predominantly associated with the Eu(3+) emiss…
The effect of cobalt doping on the structural, magnetic and magnetocaloric properties of electron-doped manganite La <sub>0.7</sub> Te <sub>0.3</sub> Mn <sub>1−x</sub> Co <sub>x</sub> O <sub>3</sub> ( <italic>x</italic> = 0, 0.1, 0.2, 0.25, 0.3 and 0.5) has been investigated.
This paper reviews a wide set of theranostic applications based on the special properties associated with composite nanogels. The nanogels presented here are mostly hybridized with quantum dots, magnetic nanoparticles, and plasmonic metal noble nanoparticles. These inorganic components confer nanogels multifunctional…
Structurally well-defined hetero-pentanuclear manganese-oxide clusters {MMn4} were successfully synthesized in TBA7Hn[MMn4(OH)2(A-α-SiW9O34)2]·2H2O·C2H4Cl2 (, M = Fe(iii), Co(ii), Ni(ii), Cu(ii), Ga(iii)) by sequential introduction of metal cations into the trivacant lacunary polyoxometalates (POMs). The pentanuclear…
The theoretical extinction coefficients of gold nanoparticles (AuNPs) have been mainly verified by the analytical solving of the Maxwell equation for an ideal sphere, which was firstly founded by Mie (generally referred to as Mie theory). However, in principle, it has not been directly feasible with experimental verif…
A general procedure for the preconcentration/recovery of lead and cadmium ions using a diethylenetriamine-functionalized magnetic graphene oxide nanocomposite.
The synthesis and characterization of the ring-unsubstituted zirconium phthalocyanine PcZrCl2 (; Pc(x-) = phthalocyaninato(x-)) and its reduction products are described. X-ray analysis of (crystallized from hot 1-chloronaphthalene) reveals that is a chloride-bridged dimer [PcZrCl]2(μ-Cl)2 in the solid-state; was also…
