ions, the visible up-conversion emissions first increase and then decrease, but NIR down-conversion emissions display a distinct trend, in which one peak at 1010 nm is highly suppressed and another at 1530 nm is increased quickly. Furthermore, the 980 nm excited optical temperature sensing property of the synthesized…
Hollow nanomaterials present an important family of nanostructures with low mass density, high porosity, large reaction surface area and good strain accommodation and have great application potentials in many fields. In this article, we reviewed our recent studies on the synthesis and property studies of hollow nanost…
Electrically conductive flexible carbon papers were prepared, based on hydroxyl functionalized few layer graphene (G-OH).
The development of synthetic chemical probes for the detection of enzymes is extremely important for biological, medicinal, and industrial applications. Here we report the synthesis of an array of novel glycosylated Tb(iii) complexes, their photophysical properties in solution, and their ability to function as lumines…
In this work, the adsorption of Rhodamine 6G molecules on some graphene substrates is investigated using density functional theory. Some simple models, such as those of perfect graphene, defective graphene, *O/*OH modified graphene and B/N doping graphene, are constructed as substrates to simulate graphene oxide and B…
Cell signaling molecules function in ZnO NPs alter cell signaling in a plant-beneficial pseudomonad to impair phenazine production between cells.
Using theoretical modeling, we demonstrate the self-assembly of functional organic molecules into 2D fractal aggregates resembling the Sierpiński triangle (ST). It is shown for the first time that the fractal self-assembly can be realized in one-component systems comprising K- and A-shaped tectons whose arms meet to f…
A novel complementary approach of environmental TEM and <italic>in situ</italic> hard X-ray ptychography was used to study the thermally induced coarsening of nanoporous gold under different atmospheres, pressures and after ceria deposition.
We report the first comprehensive study of the reactivity in organic media of (3-glycidyloxypropyl)trialkoxysilanes towards common nucleophiles. Their reactivity have to be emphasized in order to design and to improve new sol–gel hybrid synthesis.
A homoleptic, all-alkynyl-stabilized [Au8Ag8(ArC[triple bond, length as m-dash]C)16] (1, Ar = 3,5-di-tert-butylphenyl) cluster was synthesized and characterized with a single crystal X-ray structure. Reactions of 3,5-di-tert-butyl-phenylacetylene with Ag(i) and Au(i) gave [Ag(ArC[triple bond, length as m-dash]C)]n and…
Plasmon enhanced performance of bulk heterojunction solar cells involving Au nanostars, PbS/CdS core–shell QDs and TiO <sub>2</sub> nanorod arrays is demonstrated.
The dilatational properties of insoluble monolayers are important for understanding the mechanics of biological systems and consumer products, but isolating the dilatational response of an interface is challenging due to the difficulties in separating dilatation from shear and other deformation modes. Oscillations of…
The thermoelectric properties of polycrystalline materials on the basis of the solid solution Pb <sub>1−x</sub> Eu <sub>x</sub> Te prepared by spark-plasma-sintering are characterized. The solid solution undergoes a metal–semiconductor transition in parallel to the p–n transition around 500 K.
Zinc(ii)phthalocyanines (Zn(ii)Pc) have shown promising applications in photodynamic therapy due to their high quantum yield of singlet oxygen generation; however, optimization of their overall properties are required before their clinical application as photosensitizers (PSs). The photosensitization efficiency of pho…
NiO promoted dispersion of CuO in the CuO–NiO/SBA-15 composites, which showed high activity for olefin epoxidation.
Electro-thermal poling of alkali-containing glasses has been known to enhance various physical and chemical properties due to the formation of an alkali ion depletion layer. We have investigated the role of alkali ion migration in depletion layer formation by in situ impedance spectroscopy, poling current measurements…
Germanium monochalcogenides, i.e. GeS and GeSe sheets, are isoelectronic analogues of phosphorene, which have been synthesized in recent experiments (P. Ramasamy et al., J. Mater. Chem. C, 2016, 4, 479). Utilizing first-principles calculations, we have investigated their tunable electronic and magnetic properties via…
We study the optical properties of ZnO nanorods (NRs) fabricated by chemical bath deposition, hydrothermal, and the vapour–liquid–solid method (VLS). Scanning electron microscopy demonstrates differences in the structural properties for the various samples. The optical emission properties are studied by photoluminesce…
Density of nanoparticle (NP) arrays affects the hot spots distribution and strength in NP-metal film (NP-MF) geometry. In-depth understanding of the variation of electromagnetic (EM) field enhancement with NPs density is essential for wide applications of the NP-MF geometry such as surface-enhanced spectroscopies and…
