Multifunctional metal composite yarns made of crisscross-section polyester (CSP), antibacterial nylon (AN), and stainless steel wires (SSW) were manufactured using a hollow spindle spinning machine. The core yarn, the inner wrapped yarn, and the outer wrapped yarns were SSW, AN, and CSP, respectively. Process paramete…
Novel, polypropylene mesh (PPmesh) – gelatin scaffold (GELscaffold) composites are prepared from O2-plasma activated PPmesh, coated with GEL solution being in-situ structured in a 3D scaffold with by-preparation tuned, gradual porosity. The fabricated biomimetic-like composites demonstrate frequency-dependent rheologi…
Aquatic devices that can work on both water and oils have great scientific and practical significance, but the challenge remains in developing novel materials with excellent repellence to both water and oils. Here, we report that an artificial "strider" can float on both water and oils by using supporting legs with ul…
implanted Si. Local symmetry was determined by fitting crystal field parameters (CFPs), corresponding to various common symmetries, to the ground state splitting determined by photoluminescence measurements. These CFP values were then used to calculate the splitting of every J manifold. We find that both Dy and Tm ion…
The present study addresses the development of new biomass-based furan resin/glass fibre composites manufactured by the double-vacuum-bag technique using a two-stage cure cycle to allow removal of water from the resin. The volumetric composition and mechanical properties of the composites are measured and analysed wit…
Theoretical investigation of protein corona is challenging because of the size of the protein-dot complex. In this work, we have addressed this computational bottleneck by combining pseudopotential + explicitly correlated Hartree-Fock QM calculations with molecular mechanics, molecular dynamics, and Monte Carlo techni…
Electrochemically formed colored passive layers on titanium and their optical, surface morphology, and corrosion properties are presented and discussed. With the application of progressively higher AC voltages (VAC) during preparation of these passive layers, they are found to become more protective of the underlying…
We report total-energy electronic structure calculations that provide energetics of the encapsulation of polycyclic aromatic hydrocarbon (PAH) molecules coronene, sumanene, and corannulene into carbon nanotubes (CNTs) and electronic structures of the resulting carbon hybrid structures. Our calculations elucidate that…
In this letter, we report a full-metallic broadband wave plate assembled by standing metallic L-shaped stereostructures (LSSs). We show that with an array of LSSs, high polarization conversion ratio is achieved within a broad frequency band. Moreover, by rotating the orientation of the array of LSSs, the electric comp…
In this paper, a new application of equal channel angular pressing (ECAP) for fabrication of Cu–Al bimetallic tubes is presented. For the evaluation of ECAP effects, the microstructure and micro-hardness of samples are considered. To investigate of bonding properties of Cu–Al tubes, optical microscopy and shear streng…
In this work the effect of a partial replacement of CaH 2 with CaF 2 on the sorption properties of the system CaH 2 + MgB 2 has been studied. The first five hydrogen absorption and four desorption reactions of the CaH 2 + MgB 2 and 3CaH 2 + CaF 2 + 4MgB 2 systems were investigated by means of volumetric measurements,…
Competition between plastic deformation and fracture processes in metal–graphene layered composites is theoretically described. In the framework of the suggested approach, plastic deformation and fracture processes controlling the flow stress/strength of a metal–graphene layered composite are the transfer of plastic d…
Reported here are the syntheses, structures, and characterizations of four novel In–Sb–S compounds containing organic amines, namely, [PAH] 3 [In 3 Sb 2 S 9 ] (PA = n -propylamine) ( 1 ), [Fe(en) 3 ][In 2 Sb 2 S 7 ] (en = ethylenediamine) ( 2 ), [Mg(dien) 2 ][In 2 Sb 2 S 7 ]·0.5H 2 O (dien = diethylenetriamine) ( 3 ),…
A novel macromolecular intumescent flame retardant (MIFR) was synthesized. Unsaturated polyester (UP) filled with MIFR as flame‐retardant additive was prepared. The effects of MIFR on properties such as tensile strength, impact strength, flame‐retardant behavior, thermal stability, and morphology of char were studied.…
The synthesis and characterisation of a family of block codendrimers consisting of highly versatile mesogenic and carbazole-containing 2,2-bis(hydroxymethyl)propionic acid (bis-MPA) dendrons are reported. The liquid-crystal behaviour was investigated by means of differential scanning calorimetry, polarised-light optic…
The structure and various thermodynamic properties of free-standing silicene have been studied by computer simulation. Models are obtained by cooling from buckling two-dimensional (2D) liquid Si via molecular dynamics (MD) simulation with Stillinger–Weber interatomic potential. The temperature dependence of total ener…
In this work we produced tungsten (W) and W oxide (WO x ) films by pulsed laser deposition (PLD) with the aim of the addressing modifications of structure and morphology that occur after annealing treatments and high-flux deuterium plasma. Thanks to the high flexibility of PLD we produced nanostructured W containing n…
ATR-FTIR spectroscopy was used in situ to study nine unsaturated polyketones derived from cis -1,4-polybutadiene rubber, each containing a different concentration of carbonyl groups, under high-pressure CO 2 conditions (up to 100 bar). The study was aimed to systematically determine the relationship between the concen…
A trifunctional initiator with one alkyne, one hydroxyl, and one bromine group was used to construct Br-polystyrene-alkyne-poly(ε-caprolactone)-OH (Br–PS–≡–PCL–OH) diblock copolymer precursor with one terminal alkyne group located at the junction between the two blocks. Further bromination and azidation substitution o…
The adducts formed between the 4,7-Me 2 -, 3,4,7,8-Me 4 -, and 3,4,5,6,7,8-Me 6 -phenanthroline ligands and Cp* 2 Yb are shown to have open-shell singlet ground states by magnetic susceptibility and L III -edge XANES spectroscopy. Variable-temperature XANES data show that two singlet states are occupied in each adduct…
