A one-pot microwave-assisted method for synthesis of multi-walled carbon nanotubes functionalized with hexylamine as an oil based coolant for transformers.
The design and fabrication of multimodal imaging nanoparticles is of great importance in medical diagnosis. Here we report the fabrication of core-shell structured Zn2.94Ga1.96Ge2O10:Cr(3+),Pr(3+)@TaOx@SiO2 nanoparticles for persistent luminescence and X-ray computed tomography (CT) imaging. Persistent luminescent nan…
. These results highlight the ability of redox-active tetraazalene bridging ligands to enable dramatic enhancement of magnetic exchange coupling upon redox chemistry and provide a rare opportunity to examine metal-radical coupling trends across a transmetallic series of complexes.
Two-dimensional (2D) molybdenum disulfide (MoS₂) field-effect transistors (FETs) have been extensively studied, but most of the FETs with gate insulators have displayed negative threshold voltage values, which indicates the presence of interfacial traps both shallow and deep in energy level. Despite such interface tra…
A smart Pickering emulsion catalytic system is constructed, which not only exhibits fivefold reaction rate enhancement effects in comparison to the conventional biphasic system but also can be facilely demulsified by tuning pH, allowing for in situ recycling nanocatalysts.
We report a facile method to synthesize highly branched gold nanostars wrapped with nano graphene oxide (nGO) sheets with or without the addition of Raman dyes, as nanoprobes with high SERS activity. Both cysteamine and nGO are added to gold nanostars; the positively charged amino groups help self-assembly of nGO flak…
The first example of phototunable SMMs has been reported. Upon UV irradiation, variations of the coordination sphere around Dy(III) ions actually affect the magnetic behaviour of the compound via [2+2] cycloaddition reaction, leading to a magnetic transformation from the SMM behaviour to a field-induced slow relaxatio…
Vanadium pentoxide nanostructures have been obtained from an alkoxide sol–gel, prepared by a simple and inexpensive facile non-aqueous method.
Nitrogen-containing polyaniline-based carbon nanospheres (C-PANI) with diameters of about 200 nm are prepared through a direct carbonization method using polyaniline (PANI) nanospheres as carbon precursors at different temperatures.
• Exposing cells to nanosilver particles (AgNPs) immediately induces ROS. • Smaller AgNPs induce mitochondrial ROS production. • AgNP-induced mitochondrial ROS are independent of particle internalisation. Silver nanoparticles (AgNPs) induce the production of reactive oxygen species (ROS) and apoptosis. These effects a…
The mechanical strain induced fluorescence lifetime variation in hybrid bistable [Fe(H-trz) 2 (trz)]BF 4 @SiO 2 @pyrene nanoparticles.
In this study, we provide the first report on the supercapacitance behavior of titanium doped vanadium oxide films grown on vertically aligned carbon nanotubes using a chemical vapor deposition (CVD) technique.
Veratryl alcohol can be oxidized to veratryl aldehyde or veratric acid with excellent selectivity and efficient conversion under acidic and alkaline conditions using Au nanoparticles and graphene quantum dot composites (Au/GQDs) as catalysts.
The presence of water hyacinth (Eichhornia crassipes) as an aquatic plant in many lakes or other basins causes many conservation problems. Many efforts have been devoted to overcome these problems such as by utilization of water hyacinth for energy production, for water treatment, etc. In this research, cellulose was…
The inhibition effect of l -serine on the hydrogen evolution at the negative electrode of a lead–acid battery (Pb) in 5.0 M H 2 SO 4 has been studied by hydrogen evolution and electrochemical methods.
The minimum reflection loss of Fe 3 O 4 @SiO 2 @RGO nanocomposites can reach −26.6 dB at 9.7 GHz with low filler content; the mechanism was also explained.
Phosphorus doping facilitates the dispersion of copper species, enhances the interaction between metal and support, and restrains the growth of copper components during acetylene hydrochlorination.
To construct a smart drug delivery system for simultaneous cellular imaging and cancer therapy, a pH-responsive amphiphilic polymer (MPEG-hyd-TPE) with aggregation-induced emission (AIE) character was designed and successfully synthesized. Polymeric micelles self-assembled from MPEG-hyd-TPE exhibited a significant AIE…
Field-effect transistors (GFETs) were fabricated on mechanically flexible substrates using chemical vapor deposition grown graphene. High current density (nearly 200 μA μm(-1)) with saturation, almost perfect ambipolar electron-hole behavior, high transconductance (120 μS μm(-1)) and good stability over 381 days were…
A series of conjugated core–shell porous aromatic frameworks are synthesized for selective detection of nitro-explosives. The core–shell PAFs can recognize nitro aromatic explosives in the fluorescent 2D map.
