Knitted fabrics with different quantity of elastane, conspicuous by high viscosity and elasticity, having one of the most important performance properties - resistance to pilling are often used in the production of high quality sportswear. During technological process imitating operating conditions, the behaviour of k…
We study the field effect on the strain-induced Mott-insulating state of an organic superconductor $\ensuremath{\kappa}$-(BEDT-TTF)${}_{2}$Cu[N(CN)${}_{2}$]Br. The gate voltage dependences of the conductivity, Hall coefficient, and thermopower were investigated. While the conductivity obeyed an activation-type insulat…
We report a molecular modelling study to validate the forcefields [condensed-phase optimised molecular potentials for atomistic simulation studies (COMPASS) and polymer-consistent forcefield (PCFF)] in predicting the physical and thermophysical properties of polymers. This work comprises of two key steps: (1) generati…
We report the synthesis of Y1 − x Cd x FeO3 − δ nanocrystals in the range x = 0–0.2. The Y1 − x Cd x FeO3 − δ materials were shown to be single-phase by X-ray diffraction, with an average crystallite size from 23 to 34 nm, depending on composition. With increasing cadmium oxide content, the size of the Y1 − x Cd x FeO…
Bisarylamines with o-alkoxy substituents [o-NH2-C6H4-O(CH2)1/2/3]2 react with [nBu4N]4[α-Mo8O26] in anhydrous acetonitrile in the presence of N,N′-dicyclohexylcarbodiimide (DCC) to form a series of nanoscale molecular bola, bisorganoimido-bridged hexamolybdates with flexible alterable lengths, in which two hexamolybda…

This work is devoted to the study of thermomechanical properties of several industrial and model refractory materials in relation with the evolution of their microstructure during thermal treatments. The aim is, in particular, to highlight the role of thermal expansion mismatches existing between phases which can indu…
A family of Mn(III)/Ni(II) heterometallic clusters, [Mn(III)(4)Ni(II)(5)(OH)(4)(hmcH)(4)(pao)(8)Cl(2)]·5DMF (1·5DMF), [Mn(III)(3)Ni(II)(6)(N(3))(2)(pao)(10)(hmcH)(2)(OH)(4)]Br·2MeOH·9H(2)O (2·2MeOH·9H(2)O), [Mn(III)Ni(II)(5)(N(3))(4)(pao)(6)(paoH)(2)(OH)(2)](ClO(4))·MeOH·3H(2)O (3·MeOH·3H(2)O), and [Mn(III)(2)Ni(II)(2…
We study the optical properties of gapped graphene in the presence of a magnetic field. We consider a model based on the Dirac equation, with a gap introduced via a mass term, for which analytical expressions for the diagonal and Hall optical conductivities can be derived. We discuss the effect of the mass term on ele…
A series of polyurethane-polyisocyanurate (PU-PIR) foams synthesized from PET-waste-derived aromatic polyester polyols (APP) was studied using thermogravimetric analysis, Cone calorimeter and burning tests. The effect of chemical structure of the APP containing fragments of glycerol, adipic acid, poly(propylene glycol…
Screen saver: A simple and convenient route has been developed that allows peptides that catalyze the growth of the target material to be screened directly. This approach has been used to identify a peptide that induces the catalytic growth of single-crystalline ZnO nanocrystals through a nonclassical crystallization…
PURPOSE: To investigate both T1 and T2 MR relaxation enhancement of Gd substituted Zn-Mn ferrite magnetic nanoparticles. Both uncoated and polyethylene glycol (PEG) coated particles were used. MATERIALS AND METHODS: Chemical co-precipitation was used to synthesize particles in the form Mn(0.5)Zn(0.5)Gd(0.2)Fe(1.98)O(4…
In Form gebracht: Kupfer-Nanokristalle unterschiedlicher Form mit hauptsächlich {100}-Oberflächen wurde durch Reduktion von CuCl2 mit Glucose hergestellt. Die Synthesen wurden in wässriger Lösung bei 100 °C mit Hexadecylamin als stabilisierendem Reagens durchgeführt.
By combining rigid 120° dicarboxylate donors substituted with [G-0]–[G-3] Fréchet-type dendrons and complementary 120° ferrocenyl di-Pt(II) acceptors, a new family of neutral dendritic multiferrocenyl hexagons have been successfully prepared under mild conditions in high yields.
The equiatomic intermetallic compound TiFe has been prepared by elemental mechanochemical synthesis in a planetary ball mill from Fe and Ti powders. The structural and phase transformations during synthesis were followed using X-ray diffraction. The reaction of the synthesized compound with hydrogen was studied volume…
We have prepared the three novel Pd(II)-containing tungstophosphates [Pd(2)(α-PW(11)O(39)H(0.5))(2)](9-) and two structural isomers of [Pd(2)(α(2)-P(2)W(17)O(61)H(n))(2)]((16-2n)-) via simple synthetic procedures and characterized their potassium salts by single-crystal X-ray diffraction, elemental analysis, and IR an…
One-dimensional charge-transfer nanostructures were constructed by the supramolecular coassembly of amphiphilic (Amph-TTF) and hydrophobic (TDD-TTF) tetrathiafulvalene (TTF) donor derivatives with the acceptor 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F(4)TCNQ), in appropriate solvent composition mixtures.…
New schemes that exploit the unique properties of nitrogen-vacancy (NV) centers in diamond are presently being explored as a platform for high-resolution magnetic sensing. Here we focus on the ability of a NV center to monitor an adjacent mesoscopic nuclear spin bath. For this purpose, we conduct comparative experimen…
We combine the nonequilibrium Green's function method with the elastic theory to investigate the ballistic thermal transport in graphene nanoribbons under homogeneous uniaxial stretching applied in the longitudinal direction. Remarkable enhanced thermal conductance is found for the samples with width in the appropriat…
Single-walled carbon nanotube thin-film transistors (SWCNT-TFTs) with various tube diameters and constant tube length are investigated. Similar variations of on-currents, independent of the diameter, are demonstrated according to percolation theory, but off-currents significantly depend on the diameter. The temperatur…
