We present a study of Y 2– x Zn x Ru 2 O 7 pyrochlores as a function of the Zn doping level x . X-ray diffraction measurements show that single-phase samples could be obtained for x < 0.2. Within the allowed range for x, dc conductivity measurements revealed a sizable decrease in resistivity at all the investigated te…
In this paper, normal and tangential coefficients of restitution for gaseous molecules colliding with layerwise (single and few layers) graphene nanosheets were calculated using non-equilibrium molecular dynamics method. The normal and tangential coefficients of restitution depend on impact angle, velocity and landing…
Molecular dynamic simulations of systems of single-walled carbon nanotubes (CNTs) in liquid crystalline solvents were performed, in order to investigate the effect of the molecular structure and phase of the liquid crystal (LC) on the interactions between the CNTs. Three different LC molecules (5CB, 8CB and 5CF) were…
In the present study, it is demonstrated that the stereoregularity of the copolymer fraction of bimodal high-density polyethylenes (HDPEs) influences the environmental stress crack resistance. Polymer samples were characterized in terms of their semicrystalline microstructure. A certain stereoregularity was identified…
The low surface free energy makes wood plastic composites difficult to bond with traditional adhesives, such as urea formaldehyde resin (UF). This study investigates the decoration of wood flour/high‐density‐polyethylene composite (WF/HDPE) board with poplar wood veneers. High‐density polyethylene (HDPE) or maleic anh…
Spectroscopic techniques exist that may discern between enantiomers and assess chiral purity. A nonspectroscopic approach that may be directly observed could provide numerous benefits. Using chiral alanine-appended benzene-tricarboxamide gelators, we reveal a methanol gel system that is capable of providing visual dis…
Abstract Nanoribbon‐shaped nanocomposites composed of conjugated polymer poly(3‐hexylthiophene) (P3HT) nanoribbons and plasmonic gold nanorods (AuNRs) were crafted by a co‐assembly of thiol‐terminated P3HT (P3HT‐SH) nanofibers with dodecanethiol‐coated AuNRs (AuNRs‐DDT). First, P3HT‐SH nanofibers were formed due to in…
The symmetry around a Dy ion is recognized to be a crucial parameter dictating magnetization relaxation dynamics. We prepared two similar square-antiprismatic complexes, [Dy(LOMe)2(H2O)2](PF6) (1) and Dy(LOMe)2(NO3) (2), where LOMe = [CpCo{P(O)(O(CH3))2}3], including either two neutral water molecules (1) or an anioni…
BaLiF3 is an important optical crystal for use as a window material in the ultraviolet region. In this work, we studied the electronic and elastic properties of BaLiF3 with pressure effects by the generalized gradient approximation within the density-functional method. Studies indicate that BaLiF3 is mechanically stab…
Evolution of crystalline morphology/structure of PLA was investigated by combination of homemade fiber-pulling device and polarized optical microscopy, where the intense shear field within the range of the actual processing conditions was modulated by the pulling speed of glass fiber (GF). Sporadic dispersion of PLA s…
Preparation of conjugated aromatic polyimines, containing phenols in the backbone and side group substitutions, has been successfully achieved by a chemical oxidative polycondensation of a series of Schiff bases using NaOCl as the oxidant at optimum reaction temperature of 90°C. The molecular structures of synthesized…
The powders of Ce29.82Fe69.18B1.0(CeFeB) and Ce29.82Fe68.65Ga0.53B1.0(CeFeGaB) (wt%) were prepared by melt spinning. Microstructure and phase composition of the prepared powders were characterized by X-ray diffraction (XRD) and Mössbauer spectrometry. The results indicated that the as-spun ribbons comprised multi-phas…
Acrylonitrile butadiene rubber (NBR)/carbon black (CB)/nanoclay (NC) nanocomposites containing 5 phr NC and 12, 24, and 48 phr CB with resorcinol/hexamethylenetetramine as compatibilizer were prepared in an internal mixer. The possible interacting behavior between NC and CB was studied by transmission electron microsc…
Amorphous chalcogenide thin films of Ge25S75 composition have been deposited by spin-coating technique. Optical properties of thin films were investigated by spectroscopic ellipsometry in UV-MIR spectral range. Obtained results prove an increase of the thin films refractive index in the transparent region and a decrea…
The objective of the study is to present the modeling and multi-objective optimization of NOx conversion efficiency and NH3 slip in the Selective Catalytic Reduction (SCR) catalytic converter for a diesel engine. A novel ensemble method based on a support vector machine (SVM) and genetic algorithm (GA) is proposed to…
It is well-known that rotating nanobeams can have different dynamic and stability responses to various types of loadings. In this research, attention is focused on studying the effects of magnetic field, surface energy and compressive axial load on the dynamic and the stability behavior of the nanobeam. For this purpo…
Abstract A micelle‐like hybrid natural–artificial light‐harvesting nanosystem was prepared through protein‐framed electrostatic self‐assembly of phycocyanin and a four‐armed porphyrin star polymer. The nanosystem has a special structure of pomegranate‐like unimolecular micelle aggregate with one phycocyanin acceptor i…
A new method has been developed to prepare hydroxyl‐functionalized multiwall carbon nanotubes (MWCNTs‐OH) and (3‐aminopropyl)triethoxysilane‐functionalized MWCNTs (MWCNTs‐APTES), which can be uniformly dispersed in solvent‐borne polyurethane (PU) to obtain the nanocomposites with enhanced mechanical, thermal, and elec…
Thin and flexible supercapacitors with low cost and individual variation are fabricated by a new and efficient slicing method. Tunable output voltage and energy can be realized with a high specific capacitance of 248.8 F g(-1) or 150.8 F cm(-3) , which is well maintained before and after bending.
A metasurface composed of regularly arranged silicon (Si) nanospheres (NSs) with coupling was investigated both theoretically and numerically based on the Mie theory, the simple Lorentz line shape model and the finite-difference time-domain technique. By deliberately controlling the coupling strength between Si NSs th…
