We develop a luminescent platform based on Eu <sup>3+</sup> and Tb <sup>3+</sup> co-doped nanozeolite to realize the probing of amine solvents. Such a luminescence sensor can classify amine solvents and achieve an excellent fingerprint correlation between the amine solvents (with larger p <italic>K</italic> <sub>a</su…
S-PEG NIRQDs prepared from 5 kDa MPEG-SH at acidic pH provided a dramatic enhancement in the luminescence intensity. These NIRQDs were also designed with surface functional groups to attach folic acid and loaded with doxorubicin (DOX) which dramatically enhanced the uptake and efficacy of DOX (50% cell death with 15 n…
Continuous composite fibres composed of polypyrrole (PPy) nanoparticles and reduced graphene oxide (rGO) at different mass ratios were fabricated using a single step wet-spinning approach. The electrical conductivity of the composite fibres increased significantly with the addition of rGO. The mechanical properties of…
Polyurethane micelles with disulfide bonds positioned mainly either at the hydrophobic PCL junctions (PU-SS-C) or at the connections between the hydrophilic PEG and hydrophobic PCL blocks (PU-SS-I) were developed as a antitumor drug carriers.
The optical nonlinearity of dense Si quantum dots doped SiN <sub>x</sub> matrix enhanced by three orders of magnitude larger than that of stoichiometric Si <sub>3</sub> N <sub>4</sub> is demonstrated <italic>via</italic> detuning the excessive Si content from stoichiometric composition.
This paper reports a facile synthesis of N,S-doped carbon–silica nanospheres with smooth and rough surfaces by using an extended Stöber method.
Fully hydrogenated graphane nanostructures were prepared from graphite nanofibers by Birch reduction reaction.
Using the phonon Boltzmann transport formalism and density functional theory based calculations, we show that stanene has a low thermal conductivity. For a sample size of 1 × 1 μm(2) (L × W), the lattice thermal conductivities along the zigzag and armchair directions are 10.83 W m(-1) K(-1) and 9.2 W m(-1) K(-1) respe…
Through the imposition of various assumptions that have been validated using numerical analysis, a greatly simplified method has been developed for expressing the impedance of a passive metal upon the basis of the Point Defect Model. The approach has greatly decreased the dimensionality of the problem, by, for example…
In this paper, we have studied the effect of three different types of nanoparticles (NPs) ( <italic>e.g.</italic> SiO <sub>2</sub> , TiO <sub>2</sub> , and ZnO) on the interfacial tension (IFT) of different oil–water systems ( <italic>e.g.</italic> oil: <italic>n</italic> -hexane, <italic>n</italic> -heptane, <italic>…
N and P dual heteroatom doped ordered mesoporous carbon was synthesized and exhibited enhanced specific capacitance (220 F g <sup>−1</sup> at 1 A g <sup>−1</sup> ), good rate capability (178 F g <sup>−1</sup> at 16 A g <sup>−1</sup> with 81% capacitance retention) and excellent cycling stability (91% after 3000 cycles…
Staple motifs in the form of –RS(AuSR)x– (x = 1, 2, 3, etc.) are the most common structural feature at the interface of the thiolate-protected gold nanoclusters, Aun(SR)m. However, the recently solved structure of Au92(SR)44, in which the facets of the Au84 core are protected mainly by the bridging thiolates, challeng…
The water is discovered to control the selectivity by changing the surface composition of Au nanocluster or the valence state of Ag nanocluster.
We employed quantitative NMR spectroscopy and spectrophotometric absorbance titration to study a quantum dot X-type ligand exchange reaction.
Structural, local structural and optical properties of sol–gel derived Zn <sub>1−x</sub> Cr <sub>x</sub> O (0 ≤ <italic>x</italic> ≤ 0.06) nanoparticles have been thoroughly studied by several complementary techniques.
New Fe <sub>3</sub> O <sub>4</sub> nanostructures have been synthesized and added to a P(VDF-TrFE) matrix. The magnetostriction and the magnetoelectric response obtained for the 9 nm nanoparticle composites make these materials suitable for technological applications such as sensors and actuators.
The design of novel nanostructures with tailored opto-electronic properties is a crucial step for third-generation photovoltaics, and the development of cheap and environmentally compatible materials is still a challenge. Carbon quantum dots (CQDs) emerged as promising candidates but usually a low processability and p…
Pd-Au clusters of 1.8 nm preferentially catalyzed the hydrogenation of the C[double bond, length as m-dash]C bond in α,β-unsaturated aldehydes and ketones with a selectivity of ∼99%, primarily because of the unique electronic properties and isolated Pd ensembles on the ultra-small alloyed particles.
Cu <sub>3</sub> and Zn <sub>2</sub> clusters with aminotriethanolate and benzoate bridging are characterized as new catalysts for hydrocarboxylation of alkanes and cycloalkanes.
