Aiming at investigating the effect of structure on electrocatalytic properties, Pd(50)Ru(50) nanoparticles (NPs) with three different structures were carefully designed in a one-pot polyol process for application in formic acid electrooxidation. The three structures are: (1) single-phase PdRu nanodendrites (denoted as…
A magnetic visible-light response core-shell Fe3O4@SiO2@AgCl : Ag nanocomposites with enhanced photocatalytic performance has been prepared by combining polyol, sol–gel and photo-reduction methods. Room temperature magnetic hysteresis curves show that the as-synthesized Fe3O4@SiO2@AgCl : Ag nanoparticles display ferro…
Two new zinc(II) microporous metal–organic frameworks (MOFs), [Zn(dcpy)(bpe)0.5]·3H2O (1) and [Zn(dcpy)(bpe)0.5]·(CH3OH)0.5·(H2O)0.5 (2) constructed from the same initial materials 3-(2',5'-dicarboxylphenyl)pyridine (H2dcpy), 1,2-di(4-pyridyl)ethylene (bpe) and Zn(NO3)2·6H2O, exhibiting varying architectures from a 2-…
Novel organic sensitizers containing a thieno[3,4-c]pyrrole-4,6-dione (TPD) moiety with triphenylamine or julolidine as the electron donor have been designed and synthesized for quasi-solid-state dye-sensitized solar cells (DSSCs). For comparison, two organic dyes based on a terthiophene spacer have also been synthesi…
Pentavalent uranium complexes of the formula U(V)X(2)[N(SiMe(3))(2)](3) (X = F(-), Cl(-), Br(-), N(3)(-), NCS(-)) are accessible from the oxidation of U(III)[N(SiMe(3))(2)](3) through two sequential, one-electron oxidation reactions (halides) and substitution through salt metathesis (pseudohalides). Uranium(v) mixed-h…
Single perovskite slab alkylammonium lead iodides bromides (C9H19NH3)2PbI2Br2 is a new member of the family of hybrid organic-inorganic perovskite compounds. It exhibits a single structural phase transition with changes in the conformation of alkylammonium chains below room temperature. Differential scanning calorimet…
Hierarchically structured beta zeolite has been prepared under hydrothermal synthesis conditions by employing only one dual-porogenic hexaquaternary ammonium type surfactant. The resulting mesoporous molecular sieve was characterized by a complementary combination of X-ray powder diffraction, N2 adsorption–desorption…
A series of novel 1[5"-(2"'-substituted phenyl)-4",5"'-dihydro isoxazole-3"-yl]-3-[(4 substituted phenyl)imino]1-3-dihydro-2H-indole-2-one were synthesized from different substituted chalconised indole-2,3-dione was prepared from the different chalconised Isatin. The structures of the compounds were elucidated by elem…
Ten new chiral coordination polymers, namely, [Ni(L)(H(2)O)(2)] (1), [Co(L)(H(2)O)(2)] (2), [Cd(L)(H(2)O)] (3), [Cd(L)(phen)] (4), [Mn(2)(L)(2) (phen)(2)]·H(2)O (5), [Cd(2)(L)(2)(biim-4)(2)] (6), [Zn(2)(L)(2)(biim-4)(2)] (7), [Cd(L)(pbib)] (8), [Cd(L)(bbtz)] (9) and [Cd(L)(biim-6)] (10), where phen = 1,10-phenathrolin…
To satisfy the demand for high-strength steel sheets with excellent strength–ductility–hole expansion ratio balance, high-strength steels consisting of a ferrite or bainitic ferrite matrix strengthened by a large amount of finely dispersed precipitates have been developed.In this study, the influence of the precipitat…
Here we demonstrate the reversible CO2 capture capacity of polyaniline/multiwalled carbon nanotubes nanocomposite at high pressures for the first time to the best of our knowledge. High CO2 capture capacity was achieved for nanocomposite, which can be associated to the possible chemical interaction of CO2 molecules wi…
The temperature of rubber or rubber-metal springs increases under cyclic loading, due to hysteresis losses and low rubber thermal conductivity. Hysteresis losses correspond to energy dissipation from the rubber, which is primarily converted into heat. This well-known phenomenon, called heat build-up, is the primary re…
Organic/group IV nanomaterial-based solar cells attract wide research interest in the photovoltaic community because it can benefit from the advantages of both organic and group IV materials. Especially, hybrid composites of conjugated organic materials and nanostructured inorganic materials are potential candidates f…
One of the major by–products of the steel production industry is Electric Arc Furnace (EAF) slag. In the field of research and development and in cooperation with the laboratory of EGNATIA ODOS SA, the current study focuses on the mechanical properties of electric arc furnace slag, as used in the thin, porous surfacin…
We demonstrate that by using a syringe needle, plastic tubing, two glass capillaries and epoxy glue a microfluidic device can be fabricated straightforwardly that allows for the production of double emulsions, or in other words the generation of droplets-in-droplets. The device in essence is a serial combination of dr…
The use of a desymmetrized tritopic ligand with both carboxyl and pyridyl functionalities leads to the first occurrence of the [Mg(3)(μ(3)-OH)(CO(2))(6)] trimer as the 3-D framework building block in a porous crystal that shows relatively high H(2) uptake (1.37% at 77 K and 1 atm).
Five new nickel(II) complexes of 6-methoxy-2-oxo-1,2-dihydroquinoline-3-carbaldehyde 4N-substituted thiosemicarbazones with the general formula {[Ni(HL)2](NO3)2·4H2O} have been synthesised in order to ascertain the biological properties due to the change in substitution at terminal nitrogen of the thiosemicarbazones.…
Monolayers of mercaptoundecanol and mercaptoundecanoic acid were prepared on Au(111) films, immersed in aqueous solutions, and probed by frequency-modulation atomic force microscopy.
