A tetranuclear complex and a 1-D coordination polymer with a ladder-like topology have been obtained by connecting [Ni(II)Dy(III)] nodes with dicarboxylato ligands: [Ni₂(valpn)₂Dy₂(III)(pdca)₂(NO₃)(H₂O)₆](NO₃)·4H₂O 1, and (∞)¹[Ni₂(H₂O)₂(valpn)₂Dy₂(tfa)₃]·4CH₃CN 2 (valpn²⁻ = the dianion of the Schiff base resulting fro…
Sb2Te3 single-crystalline nanosheets having edge lengths of 300–500 nm and thicknesses of 50–70 nm were rapidly synthesized by a microwave-assisted method using SbCl3, Na2TeO3 and hydrazine hydrate in ethylene glycol at 200 °C for 15 min, and the reaction mechanism was proposed. The bulk sample of Sb2Te3 nanosheets wa…
Nitrogen-doped ordered mesoporous carbon was synthesized using SBA-15 as the template and polypyrrole as the nitrogen-containing carbon precursor. Transmission electron microscopy and N 2 Brunauer, Emmett, and Teller adsorption revealed a honeycomb-like ordered mesoporous structure with an average pore diameter of 3.3…
The rare earth orthochromites are extremely interesting due to the richness of their optical, dielectric, and magnetic properties as well as due to their multiferroic properties which make them suitable materials to study in the nanoregime. However, the wet-chemical synthesis of these materials in nanosize is nontrivi…
Photochromism is defined as a reversible transformation of a chemical species between two isomers upon photoirradiation. Although vast numbers of photochromic molecules have been so far reported, photochromic molecules which exhibit thermally irreversible photochromic reactivity are limited to a few examples. The ther…
The Ag(I) complex with o-bis(diphenylphosphino)benzene shows reversible interconversion between blue-emitting (1b) and green-emitting (1g) materials on grinding and heating; comparison of the structure of 1b with another green-emitting crystals (2) having the same formula suggests the chromism results from intermolecu…
A new approach to immobilizing zero-valent iron nanoparticles (ZVI NPs) into electrospun polymer nanofibers with enhanced mechanical properties for environmental applications is presented. In this approach, multiwalled carbon nanotubes (MWCNTs) are mixed with polyacrylic acid (PAA)/polyvinyl alcohol (PVA) mixture poly…
A general corrosion strategy was employed for the straightforward fabrication of a variety of metal oxide nanostructures, such as Fe3O4 octahedra, Co3O4 nanoplates, nanoporous TiO2, and Mn3O4 octahedra.
A series of propylsulfonic (MCM–SO3H) and octyl co-functionalised propylsulfonic (MCM–Oc–SO3H) catalysts have been prepared by post modification of MCM-41 with mercaptopropyltrimethoxysilane (MPTS) to achieve SO3H surface coverages spanning the range 0.12–1 monolayer. Within the MCM–Oc–SO3H series, samples with submon…
Free-standing CeO(2) nanorods with different morphology grew directly on Ti substrates via an electrochemical assembly process, and their absorption edges show a remarkable red-shift to the visible region. Moreover, photoelectrochemical cell (PEC) measurements demonstrate these CeO(2) nanorods exhibit a photovoltaic r…
Polymer electrospinning has emerged as a powerful technique for the fabrication of nanofibrous materials with high specific surface areas, controllable compositions, and high porosities for a wide range of applications. The electrospinning of biopolymers for fiber formation is of particular interest not only because t…
Biopolymer nanocomposites, which have attracted much attention due to their biodegradability and biocompatibility, have been prepared by melt blending polylactic acid (PLA)/polycaprolactone (PCL) and two types of organoclay (OMMT) include octadecylamine-montmorillonite (ODA-MMT) and fatty hydroxamic acid- montmorillon…
This critical review describes recent efforts in the field of chromophoric scaffolding. The advances in this research area, with an emphasis on rigid scaffolds, for example, synthetic polymers, carbon nanotubes (CNTs), nucleic acids, and viruses, are presented (166 references).
Mesoporous silica nanoparticles grafted with light-responsive polymer on the outer surface were developed as novel nanogated ensembles, which allow encapsulation and release of drug and biological molecules under light irradiation.
Aligned CuO nanowires (NWs) were synthesized by a simple cost-effective oxidation method. They act as cores; high density CuO/ZnO core/shell heterostructure NWs were fabricated by thermal decomposition. Using the core/shell heterostructure NWs as a photoelectrode, a 0.71% photo-to-hydrogen conversion efficiency was ob…
Starting with graphene oxide, we successfully prepared stable dispersions of reduced graphene oxide (RGO) in three hydrophilic ionic liquids (ILs) at relatively high concentration without using any surfactants/stabilizers.
We report an induction of the blue phase III (BPIII) at a relatively low and wide (over 20 °C) temperature range in nematogenic achiral bent-core liquid crystals doped with a high twisting power chiral material. The pitch decreases with increasing chiral dopant ratio, and easily reaches the ultraviolet wavelength, so…
In the work, a novel lysine-assisted hydrothermal process is first developed to produce urchin-like ordered Co(OH)2 arrays, which are assembled from mesoporous Co(OH)2 nanowires. The synergistic contributions from lysine and Cl− ions to the formation of the unique arrays was also tentatively proposed. Electrochemical…
Vapor deposited thin films (~100 nm thickness) of toluene and ethylbenzene grown by physical vapor deposition show enhanced stability with respect to samples slowly cooled from the liquid at a rate of 5 K min(-1). The heat capacity is measured in situ immediately after growth from the vapor or after re-freezing from t…
Theoretical evidence for the first neutral and anionic global-minimum structures possessing a planar pentacoordinate carbon is reported.
