Nanocomposite layers based on multiwalled carbon nanotubes (MWCNTs) and non-stoichiometric tin oxide (SnO x ) have been grown by magnetron deposition and CVD methods. In the case of the CVD method, the study of the structure and phase composition of obtained nanocomposite layers has shown that a tin oxide “superlattic…
A series of phosphors Li6Gd1-x(BO3)3:xTb3+ (0:x:1) was prepared by a conventional solid-state reaction method and their photoluminescence properties under VUV/UV excitation were demonstrated. For the excitation spectrum, the host-related absorption band, f-f and f-d transitions of Gd3+ and Tb3+, charge transfer of O2-…
For the first time, a phenomenological classification of the nucleation mechanisms of bands of macrolocalized deformation is formulated that is based on data from the high speed optical monitoring of a surface of aluminum-magnezium alloy deformed with a uniformly growing rate of applied stress, $$\dot \sigma _0 = cons…
CdSe(ZnS) core(shell) aerogels were prepared from the assembly of quantum dots into mesoporous colloidal networks. The sol-gel method produces inorganic particle interfaces with low resistance to electrical transport while maintaining quantum-confinement. The photoelectrochemical properties of aerogels and their compo…
The Hencky strain is a logarithmic strain extended to a three-dimensional analysis. Although Onaka has shown that the Hencky equivalent strain is an appropriate measure of large simple-shear deformation (2010), Jonas et al. (2011) have recently presented a paper claiming that the application of the Hencky strain to la…
Nanoparticles of a novel boron-based carbazole derivative have been reported. They exhibit efficient green fluorescence, aggregation induced ratiometric fluorescence change and green/blue fluorescent switching to sense VOCs.
A review of the history of the evolution of material science and material technology shows us that one tendency for the future could be the use of agriculture resources. In this work, we review the performances of one of these resources, that is, wheat flour. We show that it is possible to get thermoplastic films with…
Wire array templates have been utilized for fabricating various three-dimensional tubular structure devices, such as solar cells, batteries and supercapacitors, as well as electronic and photonic devices. It is necessary to remove the templates by using post-treatments such as wet chemical etching, decomposition, or K…
A series of triangular, shape-persistent arylene–ethynylene macrocycles (AEMs) of related structures were synthesized and studied, with a focus on their mesomorphic behavior in correlation with their chemical structure. Generally, these discotic molecules decorated with flexible side chains demonstrated a propensity t…
The work hardening mechanism and deformation behaviour of Hadfield steel crossing during explosion deformation were investigated by means of its ability to memorize the history of deformation and stress. The results show that the explosive stress causes little macroscopic distortion of the surface of the Hadfield stee…
In this study, we demonstrate a new strategy to image biomolecular events through interactions between liquid crystals (LCs) and oil-in-water emulsions. The optical response had a dark appearance when a nematic LC, 4-cyano-4'-pentylbiphenyl (5CB), is in contact with emulsion droplets of glyceryl trioleate (GT). In con…
Well-dispersed hierarchical straw–sheaf-like architectures of [Gd(1,4-BDC)1.5(H2O)2] (BDC2− = benzene-1,4-dicarboxylate) have been successfully synthesized via an ultrasonic-assisted solution-phase method in the presence of polyvinylpyrrolidone (PVP, 30 K). The as-obtained products were characterized by X-ray powder d…
A straightforward procedure based on the formation of intramolecular hydrogen bonds to impart selectivity in the preparation of multi-functionalized porphyrins has been developed. To illustrate the concept, the synthesis of a biomimetic artificial photosynthetic model able to undergo electron and proton transfer react…
Transparent conducting oxide (TCO) based on indium doped zinc oxide films in the nano scale were successfully prepared using combination between dip coating and thermal decomposition process. Structural investigations confirm the polycrystalline ZnO hexagonal wurtzite phase grown along the c-axis with nano crystallite…
Though the all-semiconducting nature of ultrathin graphene nanoribbons (GNRs) has been demonstrated in field-effect transistors operated at room temperature with ∼10(5) on-off current ratios, the borderline for the potential of GNRs is still untouched. There remains a great challenge in fabricating even thinner GNRs w…
Surface functionalized poly(ethylene-co-methacrylic acid) (PE-co-MAA) nanofibrous membranes were successfully prepared and applied as solid supports to immobilize photosensitizers. Several activation agents were used to facilitate the surface functionalization of PE-co-MAA nanofibrous membranes, and PCl5 was found to…
Periodic one (1D) and two dimensional (2D) arrays of copper(II) oxide (CuO) islands were successfully created by simple heat treatment of spin-coated copper acetate–polyvinyl alcohol (PVA) composites on 1D and 2D surface relief grating (SRG) templates using photodynamic polymers. Formation of CuO islands can be explai…
Cu-/Ag-modified polyoxometalates with 5/10/12 connections were obtained via a sulphur-assisted hydrothermal synthetic strategy.
Novel thin film optoelectronic devices containing both inorganic colloidal semiconductor quantum dots (QDs) and organic semiconductor thin films have been widely investigated in recent years for a variety of applications. Here, we review one of the most versatile and successful methods developed to integrate these two…
There is little in vivo data concerning the fate of ingested TiO 2 nanoparticles (nano‐TiO 2 ). We report here experiments aimed at assessing if ingested nano‐TiO 2 accumulates in the digestive gland epithelium or are internalized elsewhere in the body of the terrestrial isopod crustaceans. The animals (Porcellio scab…
