The microwave-assisted reaction of Fe(ClO(4))(2) with NaN(3), NaO(2)CPh, and 1,3-di(2-pyridyl)-1,3-propanedione gave a ferrimagnetic dodecanuclear iron(III) complex that shows magnetization relaxation behavior.
How do liquid mixtures cooled to temperatures below their freezing point behave? We address this question using nanoscale films of methanol and ethanol supercooled liquid solutions of varying composition (0−100% methanol) at temperatures near their glass transition, T g . The permeation of Kr through these films is us…
Abstract The characteristic properties of carbon nanotubes (CNTs), particularly their heat conduction, electrical conductivity, high modulus of elasticity, high strength, and resistance to chemicals, have resulted in widespread application of CNTs in nanotechnologies. In this study, CNTs were used to impart specific f…
Polymer nanocomposites (PNCs) have been synthesized using Rogers polymer and CoFe₂O₄ nanoparticles (CFO NPs). X-ray diffraction (XRD) confirms the inverse spinel crystal structure of CFO NPs and transmission electron microscopy (TEM) images show the uniform dispersion of nanoparticles (10 nm ± 1) into the polymer matr…
In this paper, the feasibility to make molded glass–ceramics transparent in the second and third atmospheric window has been investigated. The thermodynamical and viscosity properties of the base glass have been measured confirming the possibility of generating crystals during molding at different temperatures. 71 Ga…
Abstract Polypropylene/maleated (styrene‐ethylene‐butadiene‐styrene) (PP/SEBS‐ g ‐MA) blends reinforced with 0.2–2.5 wt% carbon nanofibers (CNFs) were prepared by injection molding. The structure, thermal, mechanical, and fracture behaviors of PP/SEBS‐ g ‐MA blends and their nanocomposites were studied. Wide‐angle X‐r…
A highly sensitive light-driven switch assembled by Al-doped zinc oxide (AZO) nanofibers was prepared by electrospinning. Uniform electrospun porous AZO nanofibers with an average diameter of 170 nm were observed by scanning electron microscopy and transmission electron microscopy. The small radii of Al 3+ and Zn vaca…

Anatase nanoparticles, Co x Ti 1− x O 2−δ ( x = dopant density in at % and δ = concentration of oxygen vacancy in the lattice) were synthesized using UV (λ = 254 nm)-induced photoreduction of surface preadsorbed cis -[Co III (en) 2 (MeNH 2 )Cl] 2+ complex ion on nanoscale TiO 2 particle surfaces in an aqueous solution…
Wetting on a cylindrical pillar defect is discussed in terms of the free-energy difference ΔG. Wetting is divided into wetting on a flat surface, a pinning effect at the apex of the defect, and wetting on a pillar wall. First, we confirmed that ΔG between before and after ideal wetting on a flat surface can be derived…
Inorganic nanotubes (INT) were used for the first time to prepare advanced polymer nanocomposites by means of the most simple, cost-effective and ecologically friendly way (i.e., melt-processing route). The polymer matrix was isotactic polypropylene (iPP) and the inorganic fillers were molybdenum disulfide nanotubes (…
A kind of nanoporous carbon has been successfully prepared from sugarcane bagasse through a facile microwave-induced ZnCl2 activation and tested as electrode material in ionic liquid supercapacitor. The as-prepared nanoporous carbons are systematically characterized by a variety of means such as N2 adsorption, SEM (sc…
This study investigates the thermal stability of an aerospace grade epoxy resin containing a silicate-based nanoclay modified by an organophosphorus moiety (vinyl triphenyl phosphonium bromide; VTP), double-walled carbon nanotubes (DWCNTs) and/or conventional phosphorus containing flame retardants (FRs) at weight frac…
Surface-enhanced Raman scattering (SERS) with enormous enhancements has been applied for ultra-sensitive detection in various fields, but the fabrication of large-scale, controllable and cost-effective substrates is a major challenge. We propose a novel fabrication process with a gas-assisted hot embossing process and…
Abstract To improve the crystallization and mechanical properties of poly(ethylene terephthalate) (PET), in this work, PET/SiO 2 ‐MgO‐CaO whiskers composites were prepared via in situ polymerization. The morphology, crystallization, and mechanical properties of the prepared composites were investigated. It was found t…
The C-terminal Src kinase (Csk) and Csk-homologous kinase (CHK) are endogenous inhibitors of the proto-oncogenic Src family of protein tyrosine kinases (SFKs). Phosphotyrosyl peptide binding to their Src-homology 2 (SH2) domains activates Csk and CHK, enhancing their ability to suppress SFK signalling; however, the de…
We have investigated the structural, elastic, electronic, optical and thermal properties of an insulator perovskite CsCdF3 using the pseudo-potential plane wave (PP-PW) scheme in the frame of generalized gradient approximation (GGA) and local density approximation (LDA). The computed lattice parameter and bulk modulus…
The production of inexpensive, large-scale, uniform substrates for surface-enhanced Raman scattering (SERS) is a key to popularize its usage in chemical and biological detection. We demonstrate a flexible nano-imprinted hexagonally patterned SERS-active substrate. Its electromagnetic enhancement factor was optimized b…
Single-wall carbon nanotube (SWCNT) films show significant promise for transparent electronics applications that demand mechanical flexibility, but durability remains an outstanding issue. In this work, thin membranes of length purified single-wall carbon nanotubes (SWCNTs) are uniaxially and isotropically compressed…
Orthodontic treatment is strongly dependent on the loads developed by metal wires, and the choice of an orthodontic archwire should be based on its mechanical performance. The desire of both orthodontists and engineers would be to predict the mechanical behavior of archwires. To this aim, Gum Metal (Toyota Central R&L…
