Construction of polyoxometalates from dynamic lacunary polyoxotungstate building blocks and lanthanide linkers
A series of polynuclear metal-oxo clusters have been constructed from the dynamic polyoxometalate (POM) building block {B-α-Sb(III)W9O33} and lanthanide (Ln) linkers via a stepwise synthetic strategy with the molecular formulas of [Ln2(H2O)4{WO2(pic)}2(SbW8O30)2](10-) (Na4Li6[La-1]·28H2O, Na3Li7[Pr-2]·30H2O) and [{Ln(…
Study of the Diffraction Grating on a Convex Surface as a Dispersive Element
A dispersive element in the form of the diffraction grating on a convex mirror surface is investigated. The groove profile of the grating is measured and the intensity distribution between the diffraction orders is calculated as a function of wavelength for the visible spectrum. Optomechanical elements for the require…
Modification of both d 33 and T C in a potassium–sodium niobate ternary system
In this work, we simultaneously achieved a giant d33 and a high TC in a lead-free piezoelectric ternary system of (1-x-y)K0.48Na0.52NbO3-xBiFeO3-yBi0.5Na0.5ZrO3 {(1-x-y)KNN-xBF-yBNZ}. Owing to the rhombohedral-orthorhombic-tetragonal (R-O-T) phase coexistence and the enhanced dielectric and ferroelectric properties, t…
Carbon cladded TiO 2 nanotubes: fabrication and use in 3D-RuO 2 based supercapacitors
In this work we introduce a facile procedure that allows a highly conformal coating of self-organized TiO2 nanotubes (NTs) with a graphite-like thin carbon layer. This provides a platform to enhance the functionality of TiO2 nanotubes for a wide range of applications. Here we show that such modified nanotubes can serv…
An efficient multiple healing conductive composite via host–guest inclusion
A self-healable conductive composite is developed by combining the small molecules and nanotubes through host-guest interactions. This material shows uniform conductivity, microwave absorption and humidity sensing properties, and can be rapidly healed to over 90% electrical and mechanical properties with the aid of wa…
Chemical sensor development based on poly(o-anisidine)silverized–MWCNT nanocomposites deposited on glassy carbon electrodes for environmental remediation
POAS–Ag/MWCNT nanocomposites were prepared by an adsorption process. A selective 3-methoxyphenolic sensor was developed by an I – V technique for the first time. It displays the highest sensitivity (∼3.829 μA cm −2 mM −1 ) ever published in the literature.
The enhanced efficiency of graphene–silicon solar cells by electric field doping
The graphene-silicon (Gr-Si) Schottky junction solar cell has been recognized as one of the most low-cost candidates in photovoltaics due to its simple fabrication process. However, the low Gr-Si Schottky barrier height largely limits the power conversion efficiency of Gr-Si solar cells. Here, we demonstrate that elec…
In vitro study of a pH-sensitive multifunctional doxorubicin–gold nanoparticle system: therapeutic effect and surface enhanced Raman scattering
A pH-sensitive multifunctional doxorubicin–gold nanoparticle drug delivery system, which has the potential to detect and treat tumors, was developed.
Silica shelled and block copolymer encapsulated red-emissive AIE nanoparticles with 50% quantum yield for two-photon excited vascular imaging
A polymer and silica co-protection strategy has been developed to encapsulate organic fluorogens with aggregation-induced emission and charge transfer characteristics into small nanoparticles (NPs). The co-pretected NPs show bright red fluorescence (50% quantum yield) with a large two-photon action cross-section (450…
A novel carbazole-based gold( i ) complex with interesting solid-state, multistimuli-responsive characteristics
A new carbazole-based mononuclear gold(i) complex was designed and synthesized. The novel luminogen shows significative solid-state reversible mechanochromism, dual-responsive thermochromism and sensitive thin-film vapochromism properties. In addition, we obtained two kinds of crystals of the luminogen that may explai…
Synthesis of polyethylene glycol-functionalized multi-walled carbon nanotubes with a microwave-assisted approach for improved heat dissipation
In order to improve the dispersibility of multi-walled carbon nanotubes (MWCNT) in aqueous media, MWCNT were functionalized with tetrahydrofurfuryl polyethylene glycol (TFPEG) in a one-pot, fast and environmentally friendly method.
The design of underwater superoleophobic Ni/NiO microstructures with tunable oil adhesion
Controlling oil adhesion in water is a fundamental issue in many practical applications for surfaces. Currently, almost all studies on underwater oil adhesion control are concentrated on regulating surface chemistry on polymer surfaces, and structure-dependent underwater oil adhesion is still rare, especially on inorg…

Strain-induced semimetal-to-semiconductor transition and indirect-to-direct band gap transition in monolayer 1T-TiS 2
We have investigated the effect of uniform plane strain on the electronic properties of monolayer 1T-TiS 2 using first-principles calculations. With the appropriate tensile strain, the material properties can be transformed from a semimetal to a direct band gap semiconductor.
Effect of CaO/SiO2 Ratio on Surface Tension of CaO–SiO2–Al2O3–MgO Melts
The effect of the CaO/SiO2 molar ratio on the surface tension of calcium aluminosilicate melts containing magnesia (CaO–SiO2–Al2O3–MgO) has been explored using a ring method at 1723–1823 K; the Al2O3 and MgO contents were approximately 12 and 8 mol%, respectively. The CaO/SiO2 molar ratio of the samples was varied in…
