Elastic pentacopper molecular chains, [Cu5(panapy)4X2] (X=Cl (), Br ()) and [Cu5(panapy)4]X'2 (X'=BF4 (), PF6 ()), were prepared using a naphthyridine-modulated N6-donor ligand, panapy2-, and showed magnetically coupled, dynamic rearrangement of five Cu(II) ions switched by the presence/absence of halide termination.
Novel sesquiterpene, named crossostephin (1), and coumarin, named biscopoletin (2), together with four known compounds, artesin, tanacetin, scopoletin, and scopolin, were isolated from the 70% ethanolic extract of the whole herbs of Crossostephium chinense (L.) Makino. Their structures were determined by spectroscopic…
In order to improve the adhesion strength of the DLC coating, Fine Particle Peening (FPP) treatment was employed as pretreatment for DLC coatings. FPP treatment was performed using SiC shot particles, and then the AISI316L steel was DLC-coated. The FPP treatment increased the surface roughness of the specimen, and a S…
The synthesis and characterization of superparamagnetic iron(iii) oxide nanowires confined within double-walled carbon nanotubes by capillary filling with a melted precursor (iron iodide) followed by thermal treatment is reported for the first time.
Abstract The main objective of the proposed work is to investigate the formation of nanoquasicrystalline and related nanocrystalline phases in Al—Cu—Fe system during mechanical milling at the initial stage of milling. The mechanical milling of a quasicrystalline Al 65 Cu 20 Fe 15 alloy was performed in a high-energy b…
Crystalline nanosheets were successfully formed on magnesium alloy AZ31 by a facile surfactant-free hydrothermal treatment using aqueous solution. The crystal structures and shapes of the nanosheets changed with the treatment temperature. On treatment at 120 °C, rosette-like structures made from curved nanosheets of c…
MnO 2 samples are synthesized by an electrodeposition technique at a fixed pH and are tested as active electrode material for an electrochemical supercapacitor. The physicochemical properties of electrolytic manganese dioxide, including average Mn oxidation state, amount of incorporated water, porosity, crystal struct…
Defect energetics in Σ13 pyramidal twin grain boundary (GB) of Al2O3 was investigated by a first principles projector-augmented wave method. It was found that the vacancy formation energy depends on the atomic site and the defect energetics at the GB is similar to that in the bulk Al2O3, namely the oxygen vacancy show…
This paper investigates the feasibility of injection-molded wood–fiber/high-density polyethylene (HDPE) composite foams that can replace injection-molded HDPE solids in industrial applications. The study applies injection foam molding technology using a physical blowing agent to a wood–fiber/HDPE composite, and examin…
The dicyano-substituted vinyl dipyrromethene and compound are near-planar and were prepared from a simple meso-aryl dipyrromethane via the DDQ adduct ; the unique structures of , and were confirmed by X-ray diffraction analysis.

The packing of elastic sheets is investigated in a quasi two-dimensional experimental setup: a sheet is pulled through a rigid hole acting as a container, so that its configuration is mostly prescribed by the cross-section of the sheet in the plane of the hole. The characterisation of the packed configuration is made…
The emission properties of TSPP [tetrakis(4-sulfonatophenyl) porphyrin] and TMPyP [tetrakis(4-methylpyridyl) porphyrin] in thin films, prepared both by the Langmuir–Blodgett technique and the spin-coating method, have been investigated. Surprisingly, in most of the samples analyzed, the emission spectra do not show th…
This paper investigates the sequence of morphological transitions in a nearly hard particle arrangement of colloidal crystals confined in a wedge cell. Earlier studies have shown intermediate particle arrangements (such as the buckling, rhombic, prismatic, and hcp like phases) to account for the drastic changes in the…
Mesh band-pass filters for 300-, 450-, 600-, and 750-GHz central frequencies are designed and manufactured. Copper and aluminum foil and foil-clad Teflon filters were made by chemical and ionic etching methods, and an aluminum film evaporated on a kapton film was formed by the lift-off lithography method. A gold layer…
We report the cathodic electrodeposition of cerium oxide thin films from cerium-chloride aqueous solutions on p-type Si(001) substrates under illumination. Transmission electron microscopy coupled with electron diffraction analyses show that the deposits exhibited a nanocrystalline structure with a significant amorpho…
This paper presents electrochromic properties of manganese oxide-based multilayered nanocomposite that was grown electrochemically on a transparent indium-tin oxide (ITO)-coated glass slide in a thin-film form. The composite film consists of negatively charged manganese oxide nanolayers and the intercalated cationic p…
A potential organic nonlinear optical (NLO) single crystal based on amino acid, L alaninium oxalate (LAO) is grown using the simple chiral amino acid L alanine and oxalic acid by slow evaporation method. Grown crystals have an optimum dimension of 40 x15 x 8 mm 3 with good optical quality and are characterized by powd…
In current cancer research, the application of cytotoxic T lymphocytes with specificity to tumor antigens is regarded as a real therapeutic hope. The objective of imaging is to provide a follow-up of these killer cells in real time, in order to gain a better understanding of the mechanisms and action modes of lymphocy…
A natural pollution was tested to study the pollution and self cleaning characteristics of composite insulators and porcelain insulators (type: XP-70,XWP-70) energized with AC and DC voltage. Under the station’s condition,pollution differences between different insulators and different stresses mainly appeared on the…
