Depending on the iron(ii) concentration, the mixed crystals of {[Zn1-xFex(bbtr)3](BF4)2}∞, bbtr = 1,4-di(1,2,3-triazol-1-yl)butane, 0.01 ≤ x ≤ 1, show macroscopic light-induced bistability between the high-spin and the low-spin state. In the highly diluted system with x = 0.01 and up to x = 0.31, the photoinduced low-…
A new pyridine-terminated fluorophore of ( E )-4-(2-(anthracen-9-yl)vinyl)pyridine (AnPy) with intramolecular charge transfer and aggregation-induced emission properties was synthesized and was blended with polytyrosine (PTyr) through hydrogen-bond interactions.
In order to obtain nonperipherally tetra terminal alkynyl substituted phthalocyanines (Pcs), new 3-pent-4-ynyloxy phthalonitrile (3) was prepared by the nucleophilic displacement reaction of 3-nitrophthalonitrile (1) and 4-pentyn-1-ol (2) and then cyclotetramerization was attained in the presence of zinc acetate, coba…
Pd–Pt alloy nanohypercubes were fabricated by reducing Pd and Pt precursors simultaneously with tetraethylene glycol in a one step process under microwave irradiation for only 100 s. Iodide ions were critical to their syntheses.
Abstract Herein, we have compared the behavior of ZnO and TiO2 in the photocatalytic oxidation of glycerol through detection of the main products. ZnO showed higher selectivity for the products where the carbon chain was preserved, such as glyceraldehyde (GAD) and dihydroxyacetone (DHA). TiO2 generated more products f…
Six new poly(trifluoromethyl)azulenes prepared in a single high-temperature reaction exhibit strong electron accepting properties in the gas phase and in solution and demonstrate the propensity to form regular π-stacked columns in donor-acceptor crystals when mixed with pyrene as a donor.
A simple solid-phase extraction system based on nano-structured Ni–Al layered double hydroxide was developed for the separation of thiocyanate from human saliva and serum samples before determination by gas chromatography with flame ionization detection.
Among the large number of matrixes explored as hosts for high-level nuclear wastes, conditioning of fission products and minor actinides into a homogeneous borosilicate glass is the most promising technique already implemented at the industrial scale. The advantage of this vitrification process is the volume reduction…
Nanocomposites of gold nanoparticles and semiconductor ZnO with wurtzite structure, made by solution combustion synthesis (SCS), as a function of the Zn/fuel ratio with polyethylene glycol (PEG) as fuel exhibit the presence of both nanoparticles and clusters. Atomic gold clusters present on the surface of ZnO nanorods…
A vibrating version of patchy particles in two dimensions is introduced to study self-assembly of kagome lattices, disordered networks of looping structures, and linear arrays. Discontinuous molecular dynamics simulations in the canonical ensemble are used to characterize the molecular architectures and thermodynamic…
2-phenylbenzimidazole-5-sulfonate (PBS) was immobilized into the interlayers of Zn <sub>2</sub> Al layered double hydroxides (LDHs), which exhibited remarkable violet-to-UV luminescence transformation responsing to nucleotide triphosphates compared with their diphosphate and monophosphate counterparts.
The study evaluated the performance characteristic of pulverised Palm Kernel Shell (PKS)-based particleboard. The pulverised palm kernel shell was compounded with other ingredients (such as adhesive, saw dust) in the composite development phase. Standard wood-based particleboard and pulverized PKS-wood based particleb…
Self-assembly of molecular units at an interface has been an active area of research over the past few decades because of its advantages to prepare highly ordered materials. Here we demonstrated jet flow directed supramolecular self-assembly at the interface between two aqueous solutions, one containing a cationic pol…
This study examines the impact of doping on the resistivity of sputtered cupric oxide (CuO), and investigates the effects of co-sputtering CuO with tin dioxide (SnO2). It was found that films sputtered from a 2 at. % sodium-doped target have resistivities of four orders of magnitude lower than equivalent undoped films…
A polycrystalline layer of (BEDT-TTF) <sub>2</sub> I <sub>3</sub> -based molecular conductor is transferred from a polycarbonate template to silk and other substrates for sensing and actuation applications.
Kaolinite (K), a polar and layered aluminosilicate mineral, was used as the host; ethanolamine (EOA) and ethylene glycol (EG) were inserted into the kaolinite interlayer to give the intercalated supramolecular compounds kaolinite-ethanolamine (K-EOA) and kaolinite-ethylene glycol (K-EG), respectively. The intercalatio…
A general approach towards efficient emulsion catalysis has been achieved using amphiphilic RGO–silica hybrid materials with suitable surface wettability and mesoporous structures.
Ultrathin metal films supported on transition-metal surfaces have been considered as promising catalysts as their chemical activity can be controlled by substrate strain, composition, and ligand effects, however, our atomistic understanding of the atomic structure of those systems is far from satisfactory.
The sensitivity of magnetic Barkhausen noise (MBN) profile to changes in the excitation field strength and the number of turns of the detection coil was investigated in inhomogeneous material. Generally, the 0.5 mm case depth EN 36 steel specimen shows a double peak profile indicative of inhomogeneity through the dete…
Spontaneous capillary flow (SCF) in microchannels occurs for specific geometrical and wetting conditions. When the channel walls form corner angles with the channel bottom, liquid filaments may form in the corners. These capillary filaments are often called Concus-Finn (CF) filaments, and they can theoretically spread…
