Abstract Pressure-induced crystallization from amorphous calcium carbonate (ACC) was observed with X-ray diffraction at room temperature. Time-resolved diffraction patterns revealed that calcite and vaterite simultaneously crystallized from ACC, without transformation from vaterite to calcite against Ostwald’s step ru…
-terminated mesogenic group 4-(6-amine-hexyloxy)-4*-cyan-biphenyl is chemically grafted onto the carboxylic groups of graphene oxide (GO) through an amidation reaction. The resultant mesogenic-group-modified GO sheets (GO-LC) are redispersed easily in common organic solvents, facilitating the structure characterizatio…
A regression model constructed by response surface methodology was employed to optimize the relationships between the cell density of microcellular polymethyl methacrylate foam and three independent variables: foaming pressure, temperature, and time. A Box–Behnken Design statistical approach was employed to fit the av…
Twin boundary spacing (TBS) plays a significant role in the yield behaviour of twinned nanowires (NWs). However, few studies have shown an overall view of the effects on the mechanical response of twinned silver NWs under tensile loading. In this article, the mechanical properties of 〈111〉-oriented NWs with different…
Titanium (Ti) and its alloys are widely used in dental applications due to the excellent corrosion resistance and mechanical properties. However, it has been reported that Ti is sensitive to fluor ions (F-) and lactic acid. Corrosion behaviour of the TiMo alloys, together with the currently used metallic biomaterial c…
Dense pellets of > 99% purity trirutile Cr2WO6 were prepared in one step from starting oxides using spark plasma sintering, leading to simultaneous reaction and consolidation in 3 min at 1473 K. The reducing environment during processing may be partly responsible for the rapid reaction time in these oxides, wit…
ABSTRACT Nanocomposite fibers consisting of isotactic polypropylene (iPP) as a matrix filled with vapor grown carbon nanofibers (VGCF) have been prepared and their fine crystalline structure and mechanical properties characterized. The obtained results point out that the VGCF oriented along the fiber extrusion directi…
Several approaches have been implemented to enhance the impact performance of natural fibre-reinforced composite structures. The control of reinforcement structure and fibre modification through treatment are among the approaches. The objective of this study was to evaluate the impact behaviour of woven coir-epoxy com…
In this work, the application of hyperbranched polyglycerol as a performance additive for water-based printing inks is demonstrated. The hyperbranched polyglycerol, (BPG), was synthesized through anionic ring-opening polymerization from glycidol using 1-butanol as the starting material. The branched structure of BPG i…
The interface between a ferroelectric Fe3O4 thin film and a semiconducting 0.05 wt. % Nb:SrTiO3 substrate was investigated by ferroelectric, pyroelectric, capacitance, transport, and nonlinear dielectric microscopy measurements. Ferroelectric polarization measurements showed that the magnetite films are ferroelectric…
A poly(ethylene terephthalate) (PET)/allylisobutyl polyhedral oligomeric silsesquioxanes (a‐POSS) nanocomposite is prepared by a solvent‐casting method and as‐received PET (asr‐PET) is modified by a precipitation method to yield precipitated PET (p‐PET). Their crystallization behaviors have been studied, and both modi…
Accurate quantum chemical calculations on real-world magnetic systems are challenging, the inclusion of electron correlation being the bottleneck of such task. One method proposed to overcome this difficulty is the embedded fragment approach. It tackles a chemical problem by dividing it into small fragments, which are…
Novel nanocomposites based on gelatin polymer networks containing poly(lactic-co-glycolide) (PLGA) nanoparticles (PLGA-NPs) were prepared and morphological, chemical and rheological properties were investigated. The successful incorporation of PLGA nanoparticles into the gelatin gels was confirmed by field emission sc…
Thermoplastic vulcanizates (TPVs) based on poly (vinylidene fluoride) (PVDF), silicone rubber (SR) and fluororubber (FKM) were prepared via dynamic vulcanization. Morphology characterization showed that spherical rubber particles were dispersed separately and “connected” by “bridge” in the TPV with 10 wt.% FKM, but aggl…
In this paper, transfer function of a colloidal quantum dot infrared photodetector (CQDIP) is derived considering the system rate equations, to study the modulation response of a CQDIP. The presented transfer function models the system reaction to different modulation frequencies of input optical signals. Theoretical…
The crystallization, including both the phase diagram and the phase transition of hen egg white lysozyme (HEWL) was investigated. A tetragonal modification and a needle modification were obtained during crystallization. The phase diagram and stability of two modifications in both acid and basic pH solutions (pH 4.5, 8…
Using molecular dynamics, we have studied the behaviour of cylindrical [001]-oriented Fe and FeCr nanowires under uniaxial tensile strain with both an embedded atom method (EAM) and a Tersoff-like bond order potential. The mechanical properties were analysed and the deformation mechanism was studied and compared betwe…
Assemblies of plasmonic nanoparticles possess exotic properties that are used in numerous applications. Their efficiency for specific applications strongly depends on the modes supported by the structure. In this paper, we extend the Green’s tensor formalism to compute the eigenmodes of an assembly of plasmonic…
We quantified interfacial adhesion in ternary blends with matrix/shell/core microstructure based on mechanical properties assessments. Various HDPE-based ternary blends containing PA-6/EVOH core/shell droplets were prepared by changing composition and processing temperature. The theoretical predictions of tensile prop…
ABSTRACT Macroscopic thermal and mechanical properties of complex aliphatic polycarbonate‐based polyurethane (PU) films containing degradable ester units in PU backbone were studied by a combination of several experimental techniques. Differential scanning calorimetry (DSC) revealed that the synthesized oligomeric dio…
