New nanocomposite hydrogels from liquid crystalline brush-like block copolymers (LCBBCs) and gold nanorods (AuNRs) were synthesized and characterized. The hydrogels protected and stabilized AuNRs, which presented peroxidase-like activity and catalysed the oxidation of a substrate in the presence of H2O2 and elicited a…
Aluminum complexes bearing unsymmetrical dinaphthalene-imine ligands were employed for lactide polymerization.
Cooling of tokamak boundary plasma owing to radiation of non-fully stripped lithium ions is considered as a promising way for protection of plasma facing elements (PFE) in tokamak. It may be effectively realized when the main part of lithium ions are involved in the closed circuit of migration between plasma and PFE s…
A straightforward preparation and detailed characterization of cobalt-based nanoparticles incorporated within a N-doped graphene-type matrix attached to ceria as support (Co 3 O 4 /NGr@CeO 2 ) is demonstrated. In general, the active catalytic material is provided by wet impregnation of ceria with a nitrogen ligated–co…
. More importantly, the low-toxic NIR-emitting HgS/ZnS NCs have proved to be an effective fluorescent label in in vitro and in vivo imaging. The penetration depth reached 2 cm in a nude mouse with distinct separation of autofluorescence and NCs' fluorescence, giving excellent contrast at all depths. The novel highly-l…
The wide application and production of nanotechnology have increased the interest in studying the toxicity of nano- and micro-sized particles escaping into air from various aspects of the production process. Metal oxides (MOs) are one particular class of particles that exist abundantly in ambient PM. Studies show an e…
Controlled morphology and energy transfer in assembled spherical YP x V 1−x O 4 :Ln 3+ (Ln = Eu, Sm, Dy or Tm) phosphors with higher luminescent quantum efficiency by the EDTA-assisted hydrothermal method.
Metal nanostructures have attracted great attention in various fields due to their tunable properties through precisely tailored sizes, compositions and structures. Using mesoporous silica (mSiO2) as the inorganic capping agent and encapsulated Pt nanoparticles as the seeds, we developed a robust seeded growth method…
A high performance supercapacitor was obtained with an electrode composed of a hybrid material of nitrogen-functionalized graphene with polyaniline.
Two novel thermo-responsive polymer brushes were prepared from L-alanine derivatives using the surface-initiated atom transfer radical polymerization (SI-ATRP) technique. The temperature-induced cell capture and release on both polymer brush modified substrates were further explored.
High dehydrogenation kinetics are shown to be the result of a low activation energy combined with an amorphous and nanocrystalline structure.
A novel and efficient nitrogen-doped carbon nanotube (A-M-CNT) catalyst has been prepared by a facile two-step method, including prior air activation and subsequent pyrolysis of the carbon nanotubes with melamine. The as-synthesized A-M-CNT affords superior catalytic activity to the nitrogen-doped CNT without air acti…
Co3O4 nanocubes were synthesized via a simple hydrothermal method. X-ray diffraction (XRD) and high-resolution transmission electron microscopy (HRTEM) analysis revealed that the product was cubic single crystal Co3O4, with the width of several ten nanometers to several hundred nanometers. The influence of reaction te…
A real-time reversible fusion pathway from vesicles to fibres, passing through several types of intermediates such as fused vesicles and short and long tubes, was monitored in a cholesterol-based assembly. The mechanism of the structural evolution via a gelation process was studied by means of electronic microscopy, s…
Systematic atomistic simulations of homo- and hetero-phase boundaries have been carried out to quantify interphase boundary energies in iron including δ-phase and γ-phase grain boundaries and δ/γ, δ/liquid and γ/liquid interfaces. Due to structural mismatch between body centered cubic (BCC) and face centered cubic (FC…
This work describes a series of side-on and end-on SCLCPs with an optically active polynorbornene main chain and achiral mesogens. The side-on SCLCPs tend to form achiral mesophases, while their comparative end-on analogues exhibit chiral mesophases.
Broadening of excitation bands and color-tunable emission of Ce 3+ , Tb 3+ co-doped Ca 5 (BO 3 ) 3 F phosphors are reported.
SEM of nanocrystals synthesized through bottom up approach.
Transparent inorganic/organic nanocomposites are fabricated, which enable tunable upconversion emission covering the entire color space.
Linking multiple paramagnetic gadolinium(III)-chelates based on the 2-[4,7,10-tris(carboxymethyl)-1,4,7,10-tetraazacyclododec-1-yl]acetate (DOTA) ligand to the surface of NaGdF4:Yb(3+),Tm(3+) upconverting nanoparticles with an average particle size of 20 nm resulted in an assembly that has favorable properties for bim…
