Here, we report a simple and ultrasensitive upconversion fluorescent strip sensor based on NaYF4:Yb,Er nanoparticles (NPs) and the lateral flow immunochromatographic assay (LFIA). Carboxyl-modified β-NaYF4:Yb,Er NPs were successfully synthesized by a facile one-pot solvothermal approach, upon further coupling with mon…
Novel nanofibers from blends of polylactic-co-glycolic acid (PLGA) and chitosan have been produced through an emulsion electrospinning process. The spinning solution employed polyvinyl alcohol (PVA) as the emulsifier. PVA was extracted from the electrospun nanofibers, resulting in a final scaffold consisting of a blen…
This paper reports on the effect of the fabrication process on the conductivity of BZY10 (BaZr0.9Y0.1O3−δ). The dense specimens were prepared by four methods: (1) solid-state reactive sintering (SSRS), (2) conventional sintering using powder prepared by solid-state reaction and NiO as sintering aid, (3) conventional s…
Water-soluble fluorescent carbon nanodots (CNDs) were fabricated directly from polyethylene glycol (PEG) by a simple one-pot thermal treatment. In the formation of such CNDs, PEG played two essential roles: the carbon source and surface passivating agent. CNDs were used directly without any additional separation or pu…
The first immobilization of the trivacant Keggin-type polyoxometalate ([A-PW9O34]9−, PW9) to prepare a novel heterogeneous oxidative catalyst is here reported. PW9 was incorporated into the cavities of the chromium terephthalate metal–organic framework MIL-101(Cr). Characterization of the composite PW9@MIL-101 by powd…
A facile, inexpensive and potentially scalable technique has been developed to fabricate well designed CuO NRs on tentacle-like nanoporous Ni/Ni foam for high-performance supercapacitors.
ZnO nanocrystals of different shapes and sizes have been synthesized using an innovative methodology and various polysaccharides as sacrificial templates.
A layered erbium(III) phosphonate compound, [Er(notpH4)(H2O)]ClO4·3H2O (1), in which the Er(III) ion has a pseudo-D5h symmetry exhibits field tunable multiple magnetic relaxation. The near-IR emission spectrum of 1, excited at 1064 nm (Nd:YAG laser), provides a direct probe of the crystal field splitting correlated to…
Herein, we demonstrate that ZnO nanowire arrays could be rationally connected with each other by thin Au nanowires to construct a novel cross-linked hetero-structure by a simple photo-directed growth strategy, which exhibit much higher visible light photocurrent density than traditional Au nanoparticle/ZnO nanowire he…
The thermoelectric properties of Mg–Sb single crystals, which are compared with their polycrystalline counterparts, are enhanced by introducing Mn.
Ordered transparent thin films based on alternate layer-by-layer assembly of lanthanide complexes and layered double hydroxide nanosheets have been fabricated, which exhibit up-conversion emission and tunable two-color luminescence.
A series of porphyrin-based porous aromatic frameworks are synthesized through a facile approach, and they possess high adsorption capacity and high adsorption selectivity values of small hydrocarbons.
A highly sensitive, tunable, flexible and microfluidic compatible gas sensor was developed based on a photochromic spiropyran-embedded PDMS composite.
In this work, three polyimides (PIs) are successfully synthesized by the condensation reaction of an aromatic triamine with three difunctional aromatic dianhydrides. These materials show electrochemical lithium ion storage properties as cathodes for lithium-ion batteries. The aromatic dianhydride monomers are found to…
We report on the synthesis of ZnO nanoplates and ZnO nanoplate/Ag nanoparticle heterostructures <italic>via</italic> a simple and cost effective wet chemical precipitation method.
Density functional studies have been performed on ten different {Gd(III)-radical} complexes exhibiting both ferro and antiferromagnetic exchange interaction with an aim to assess a suitable exchange-correlation functional within DFT formalism. This study has also been extended to probe the mechanism of magnetic coupli…
Three phthalocyanines (Pcs) conjugated with α-, β- and γ-cyclodextrins (CDs) were prepared and their application as photosensitizer (PS) agents was assessed by photophysical, photochemical and in vitro photobiological studies. The photoactivity of Pc-α-CD and Pc-γ-CD ensures their potential as PDT drugs against UM-UC-…
In this paper, the anisotropic thermal conductivity characteristics of graphene wrinkles are observed for the first time using a non-equilibrium molecular dynamics method. Our results reveal that the wrinkling level has little effect on the thermal conductivity along the wrinkling direction. However, the wrinkling lev…
Freestanding Ta2O5 nanotubes were prepared by an anodizing method. As-anodized amorphous nanotubes were calcined at high temperature to obtain a crystalline phase. All materials were studied by means of BET analysis, XRD, TEM, SEM, XPS, and FTIR and were evaluated in the catalytic oxidation of CO. An XPS study confirm…
Supramolecular polymer networks with different strengths of transient connectivity can be formed with nanometer-scale topologies close to those of regular model networks by transition-metal complexation of monodisperse star-shaped building blocks with terpyridine endgroups.
